Their past adaptations reveal insights for conservation today. Many people picture our earliest primate ancestors moving through dense tropical forests, yet new evidence suggests they actually endured cold environments. As an ecologist who has spent years studying chimpanzees in Uganda and lemurs in Madagascar, I am deeply interested in the habitats that influenced our evolutionary history. These discoveries challenge long-held ideas about when and where our lineage first developed. Understanding the origins of human evolution is central to understanding ourselves. The same environmental pressures that shaped our ancestors continue to shape us today and will influence our future as well. Climate as a driver of evolution Climate has always played a critical role in determining which species thrive, which adapt, and which vanish. With global temperatures rising, insights from the past are more valuable than ever. A recent study led by Jorge Avaria-Llautureo at the University of Reading, along with colleagues, examined the geographic origins of primates and the climates of those ancient regions. The findings were unexpected: instead of emerging in warm, tropical habitats as previously assumed, the earliest primates appear to have lived in cold, arid environments. Teilhardina was one of the first primates. Credit: Mark Klingler, Carnegie Museum of Natural HistoryThese environmental challenges are likely to have been crucial in pushing our ancestors to adapt, evolve and spread to other regions. It took millions of years before primates colonized the tropics, the study shows. Warmer global temperatures don’t seem to have sped up the spread or evolution of primates into new species. However, rapid changes between dry and wet climates did drive evolutionary change. Earliest primates and their traits One of the earliest known primates was Teilhardina, a tiny tree dweller weighing just 28 grams – similar to the smallest primate alive today, Madame Berthae’s mouse lemur. Being so small, Teilhardina had to have a high-calorie diet of fruit, gum and insects. Fossils suggest Teilhardina differed from other mammals of the time as it had fingernails rather than claws, which helped it grasp branches and handle food – a key characteristic of primates to this day. Teilhardina appeared around 56 million years ago (about 10 million years after the extinction of the dinosaurs) and species dispersed rapidly from their origin in North America across Europe and China. It is easy to see why scientists had assumed primates evolved in warm and wet climates. Most primates today live in the tropics, and most primate fossils have been unearthed there too. Cold origins and surprising habitats But when the scientists behind the new study used fossil spore and pollen data from early primate fossil environs to predict the climate, they discovered that the locations were not tropical at the time. Primates actually originated in North America (again, going against what scientists had once believed, partly as there are no primates in North America today). Over 56 million years, primates have evolved into all sorts of shapes and sizes. Credit: Monkeys: Our Primate Family exhibition at the National Museum of Scotland/Jason GilchristSome primates even colonized Arctic regions. These early primates may have survived seasonally cold temperatures and a consequent lack of food by living much like species of mouse lemur and dwarf lemur do today: by slowing down their metabolism and even hibernating. Challenging and changeable conditions are likely to have favored primates that moved around a lot in search of food and better habitat. The primate species that are with us today are descended from these highly mobile ancestors. Those less able to move didn’t leave any descendants alive today. Lessons for conservation today The study demonstrates the value of studying extinct animals and the environment they lived in. If we are to conserve primate species today, we need to know how they are threatened and how they will react to those threats. Understanding the evolutionary response to climate change is crucial to conserving the world’s primates, and other species beyond. When their habitats are lost, often through deforestation, primates are prevented from moving freely. With smaller populations, restricted to smaller and less diverse areas, today’s primates lack the genetic diversity to adapt to changing environments. But we need more than knowledge and understanding to save the world’s primate species, we need political action and individual behavior change, to tackle bushmeat consumption – the main reason primates are hunted by humans – and reverse habitat loss and climate change. Otherwise, all primates are at risk of extinction, ourselves included. Reference: “The radiation and geographic expansion of primates through diverse climates” by Jorge Avaria-Llautureo, Thomas A.

Ted Cruz claims without evidence that China is funding U.S. climate lawsuits

Republican Sen. Ted Cruz has said China is funding climate lawsuits against American oil and gas companies to weaken the U.S. He hasn't provided evidence to support the claim.

(Marcio Jose Sanchez | AP)States and localities have filed waves of lawsuits against the fossil fuel industry to make energy companies pay for damages that communities face from climate change. Threatened with potentially huge financial penalties, industry and its supporters recently turned to the Supreme Court for help — without success. Now, Sen. Ted Cruz, the Texas Republican, has launched a new line of attack that could help industry by focusing on the money that’s allegedly behind the climate cases. At a June hearing on Capitol Hill, Cruz accused China of funding the lawsuits in order to cripple U.S. oil and gas producers and to strengthen Beijing’s position in global energy markets. If the community court cases succeed, Cruz said U.S. energy production would fall and prices would rise. “And the biggest winner in all of this: China, who’s paying the bills,” he said. However, Cruz’s office has not offered evidence that China or a China-linked nonprofit that Cruz identified by name has funded climate lawsuits in the United States. A spokesperson for Cruz, Macarena Martinez, provided NPR with a response from ChatGPT that reads, in part: “What’s not publicly demonstrated (so far) is a direct, documented grant-to-lawsuit pipeline.” Cruz’s unsubstantiated claim is part of a yearslong effort by the fossil-fuel industry and its allies to fight lawsuits that state and local governments have filed against oil and gas companies, according to environmental advocates and Democratic lawmakers. The litigation alleges that corporations misled the public for decades about the dangers of burning fossil fuels, the primary cause of climate change. The lawsuits seek money to help communities cope with the risks and harms from global warming, including more extreme storms, floods and heat waves. For years, Republican lawmakers have probed the funding sources for America’s environmental movement. That scrutiny has focused more recently on climate litigation as cases proliferated around the country. This summer, a group of Republican state attorneys general called for a federal law to protect energy companies from “activist-funded climate lawsuits.” Ryan Meyers, general counsel for the American Petroleum Institute, a trade group for the oil and gas industry, said in a statement to NPR that the climate lawsuits are “baseless” and a “coordinated campaign” against energy companies. “Climate policy belongs in Congress,” Meyers said, “not a patchwork of courtrooms.” The American Petroleum Institute would not comment on the record about Cruz’s allegation that China is funding the lawsuits. John Chung-En Liu, an associate professor of sociology at National Taiwan University who has studied Chinese climate propaganda on social media, says framing U.S. climate litigation as a China-funded campaign is “an easy tactic” to whip up opposition. “China doesn’t have a very good name in Washington, D.C.,” Liu says, and Beijing does try to influence politics and public opinion globally on a range of issues. China’s embassy in Washington did not respond to messages seeking comment for this story. Sen. Ted Cruz departs a meeting with Senate Republicans in the U.S. Capitol in June.

(Al Drago/Getty Images | Getty Images North America)‘We should be very careful to actually know what’s real and what’s not’ The alleged funding scheme that Cruz described in June revolves around a nonprofit called Energy Foundation China. Headquartered in San Francisco with an office in Beijing, the group is led by a former official at China’s National Center for Climate Change Strategy and International Cooperation. Last year, GOP lawmakers asked Energy Foundation China for documents related to its funding of U.S. organizations. At the Senate hearing this summer, Cruz said Energy Foundation China is “one of the primary vehicles” for an international alliance between “leftist billionaires, radical environmental organizations and the Chinese Communist Party.” “And this money isn’t going to tree-planting campaigns or to science fairs,” Cruz said. “It’s flowing directly to aggressive litigation outfits, like the Natural Resources Defense Council, the Rocky Mountain Institute and the World Resources Institute.” Energy Foundation China has given money to all three of those groups, according to tax filings. But Sen. Sheldon Whitehouse, a Democrat from Rhode Island, said at the June hearing that Cruz hadn’t provided evidence that the money was used to pay for U.S. lawsuits — as opposed to trying to cut climate pollution in China. “If it turns out that China is supporting lawsuits in the United States, that would be extremely troubling. And so I think we should be very careful to actually know what’s real and what’s not,” says Ilaria Mazzocco, a senior fellow who focuses on Chinese business and economics at the Center for Strategic and International Studies. A spokesperson for the Rocky Mountain Institute, Adam Beitman, said in a statement to NPR that the nonprofit does not participate in litigation, and that all of the funding it has received from Energy Foundation China “is focused squarely on the energy transition inside of China.” A spokesperson for the World Resources Institute, Alison Cinnamond, said her organization does not participate in litigation, nor does it direct legal action by other groups. “WRI’s work in China focuses on issues like air quality, sustainable cities, energy efficiency, and resilience — areas that are essential for global well-being,” Cinnamond said in a statement. Michael Wall, the chief litigation officer for the Natural Resources Defense Council, says the nonprofit has used funding from Energy Foundation China exclusively for programs to cut climate pollution in China. In the U.S., NRDC has sued government agencies and corporations that have violated environmental laws, Wall says, and the nonprofit is defending state laws in New York and Vermont to force fossil fuel companies to help cover the costs of climate change. An executive at Energy Foundation China, Vance Wagner, said in a statement that the nonprofit is an independent organization that funds research and other initiatives to address climate change in China, which is the biggest source of heat-trapping pollution globally. Wagner said the group doesn’t fund or engage in activism, litigation or lobbying in any country. An oil pumpjack is seen near a field of wind turbines in Nolan, Texas. (Brandon Bell/Getty Images | Getty Images North America)Republican attorneys general want to shield energy companies from lawsuits Days before Cruz accused China of bankrolling the climate cases, more than a dozen Republican state attorneys general sent a letter to U.S. Attorney General Pam Bondi asking the Justice Department to recommend federal legislation to give energy companies a “liability shield” to protect them from climate litigation. The Justice Department’s Office of Policy and Legislation is charged with developing legislative proposals, among other duties. Earlier this month, for example, the department sent Congress proposed legislation that would prohibit doctors from providing gender-affirming care to children. In the letter to Bondi, the Republican attorneys general wrote that the legal protection they want to create for energy companies is similar to a 2005 law called the Protection of Lawful Commerce in Arms Act, which generally shields gun manufacturers and dealers from civil lawsuits when firearms are used in criminal activity. Kansas Attorney General Kris Kobach, a Republican who signed the letter to Bondi, then served as an expert witness at Cruz’s hearing about China. “I think that where Congress can be helpful in these [climate] cases is in getting to the bottom of where the money is coming from,” Kobach said at the hearing. Cruz’s allegation of Chinese funding was designed “to create political cover” for Congress to give fossil fuel companies legal immunity from climate litigation, says Richard Wiles, president of the Center for Climate Integrity, which supports climate lawsuits against the fossil fuel industry by filing legal briefs and providing plaintiffs with documents. The Justice Department did not respond to messages seeking comment. So far, the climate lawsuits filed by states and localities have had mixed results. Some cases have been dismissed by judges who ruled that climate pollution is an issue for the federal government to deal with. But other lawsuits are moving toward trial. In January, the Supreme Court rejected an effort by oil and gas companies to block a climate lawsuit filed by Honolulu. And in March the justices turned down a request by Republican attorneys general to stop climate lawsuits filed by states including California, Connecticut, Minnesota and Rhode Island. “All these communities are asking is that the oil industry pay their fair share of the damages that they knowingly cause,” Wiles says. “It’s completely reasonable.” In a legal brief challenging a lawsuit that Boulder, Colorado filed against oil and gas companies, the Justice Department recently told the Supreme Court that allowing climate litigation to move forward in state courts exposes energy companies to billions of dollars in damages, as well as a confusing assortment of local regulations.

In 2023, Cruz and Rep. James Comer, a Kentucky Republican, asked for financial information from Sher Edling, a law firm that’s filed many of the climate lawsuits brought by states and localities. Last year, The Free Beacon, a conservative news site, published a Congressional memo that detailed funding that several nonprofits have given to Sher Edling. Since that money came from tax-exempt organizations, taxpayers effectively have been “bearing the cost” of Sher Edling’s legal work, according to the memo, which was written by Republican staffers on the Senate Commerce, Science and Transportation Committee and the House Committee on Oversight and Accountability. The memo added: “Although not illegal, this structure allows the green mafia to achieve its political goals while lowering its tax bill.” The Congressional memo names three nonprofits that gave money to Sher Edling: New Venture Fund, the Tides Foundation and Resources Legacy Fund. Tax filings show that all three got funding from Energy Foundation China, but two of them got those grants before they started funding Sher Edling. Of the three, Resources Legacy Fund in 2017 got $185,00 from Energy Foundation China, according to an Energy Foundation China tax filing. The money was meant “to promote education and analysis to build markets for clean, affordable energy that protects public health.” That same year, Resources Legacy Fund gave Sher Edling about $432,000 for “land or marine conservation,” according to a Resources Legacy Fund tax filing. Resources Legacy Fund did not respond to messages seeking comment. Neither did the Tides Foundation. New Venture Fund declined to comment. Sher Edling declined to comment for this story. Wall of the Natural Resources Defense Council rejected the idea that philanthropic funding has unfairly disadvantaged oil and gas companies in court. “There’s simply no comparison between the resources the oil industry has and the resources that nonprofits have,” he says. “Litigation is a way for people to participate in the governmental process by working to ensure that the laws that protect them are enforced and carried out.” In a letter to Cruz and Comer last year that was obtained by NPR, a lawyer for Sher Edling wrote that fossil fuel companies that are defendants in the climate cases “fear that the communities will prevail in those lawsuits — and so they now hope that you will run interference for them. Respectfully, you should not.” When Cruz accused China of funding U.S. climate lawsuits this summer, he said Beijing’s goal is to establish “global energy dominance and control.” China is the world’s biggest producer of green technology, like solar panels and electric vehicles. And Republican lawmakers and conservative activists for years have argued that climate policies that shift the U.S. away from fossil fuels would make America dependent on Chinese supply chains. But Liu of National Taiwan University says Beijing is probably content to have the U.S. focus on oil and gas, rather than to challenge China in other parts of the energy market. “China wants to be the leader in the key technology in the future, so that they don’t have to be controlled by the West,” Liu says, adding: “If we are following this train of thought, then they will prefer [the] U.S. not taking climate very seriously, and let China take over all the EVs, take over solar and wind.”

Trump will reportedly link autism to pain reliever Tylenol - but many experts are sceptical

Some studies have suggested an association between the two, but experts say there is no causal relationship.

Trump officials are expected to link the use of pain reliever Tylenol in pregnant women to autism, according to US media reports. At an Oval Office event on Monday, the US president will reportedly advise pregnant women in the US to only take Tylenol, known as paracetamol elsewhere, to relieve high fevers.At the Charlie Kirk memorial service on Sunday, Trump said he had an "amazing" announcement coming on autism, saying it was "out of control" but they might now have a reason why.Some studies have shown a link between pregnant women taking Tylenol and autism, but these findings are inconsistent and do not prove the drug causes autism. Tylenol is a popular brand of pain relief medication sold in the United States, Canada and some other countries. Its active ingredient is acetaminophen, which is called paracetamol outside North America.Tylenol maker Kenvue has defended the use of the drug in pregnant women.In a statement to the BBC, it said: "We believe independent, sound science clearly shows that taking acetaminophen does not cause autism. We strongly disagree with any suggestion otherwise and are deeply concerned with the health risk this poses for expecting mothers."Acetaminophen is the safest pain reliever option for pregnant women, it added, and without it, women face a dangerous choice between suffering through conditions like fever or use riskier alternatives.The BBC has contacted the Department of Health and Human Services (HHS) for comment. In April, the leader of HHS, Robert F Kennedy Jr, pledged "a massive testing and research effort" to determine the cause of autism in five months.But experts have cautioned that finding the causes of autism - a complex syndrome that has been researched for decades - would not be simple. The widely held view of researchers is that there is no single cause of autism, which is thought to be the result of a complex mix of genetic and environmental factors.The American College of Obstetrics and Gynecology said doctors across the country have consistently identified Tylenol as one of the only safe pain relievers for pregnant women."[S]tudies that have been conducted in the past, show no clear evidence that proves a direct relationship between the prudent use of acetaminophen during any trimester and fetal developmental issues," the group has said. The drug is recommended by other major medical groups as well as other governments around the world. In August, a review of research led by the dean of Harvard University's Chan School of Public Health found that children may be more likely to develop autism and other neurodevelopmental disorders when exposed to Tylenol during pregnancy. The researchers argued some steps should be taken to limit use of the drug, but said the pain reliever was still important for treating maternal fever and pain, which can also have negative effects for children. But another study, published in 2024, found no relationship between exposure to Tylenol and autism. "There is no robust evidence or convincing studies to suggest there is any causal relationship," said Monique Botha, a professor in social and developmental psychology at Durham University. Dr Botha added that pain relief for pregnant women was "woefully lacking", with Tylenol being one of the only safe options for the population. Autism diagnoses have increased sharply since 2000, and by 2020 the rate among 8-year-olds reached 2.77%, according to the US Centers for Disease Control and Prevention (CDC).Scientists attribute at least part of the rise to increased awareness of autism and an expanding definition of the disorder. Researchers have also been investigating environmental factors.In the past, Kennedy has offered debunked theories about the rising rates of autism, blaming vaccines despite a lack of evidence.

Lyme Disease: What To Know About Symptoms, Treatment & Prevention

By Charlotte Mao, MD, MPH, Bay Area Lyme Foundation HealthDay ReporterMONDAY, Sept. 22, 2025 (HealthDay News) — Lyme disease is the most common...

MONDAY, Sept. 22, 2025 (HealthDay News) — Lyme disease is the most common vector-borne illness in the United States, a potentially disabling infection caused by bacteria transmitted through the bite of an infected tick to people and pets.Another possible route of transmission, which is less well known and understudied, is from an infected pregnant mother to her unborn baby.Each year, the U.S. sees about 500,000 new cases of Lyme disease, according to statistics released in 2018 by the U.S. Centers for Disease Control and Prevention (CDC).Here’s what to know about how Lyme disease spreads, symptoms to watch for, treatment options and how to live well even if symptoms persist.What Is Lyme disease?Lyme disease is an infection caused mainly by the bacterium Borrelia burgdorferi in the United States. The bacteria are transmitted to humans through the bite of infected blacklegged ticks: the Western blacklegged tick (Ixodes pacificus) and Eastern blacklegged tick (Ixodes scapularis), sometimes called a deer tick.The disease was first recognized in the 1970s after an outbreak in Lyme, Connecticut. Today, Lyme has been reported in all 50 states. However, while the geographic areas inhabited by ticks that carry Lyme-causing bacteria have expanded, ticks carrying these bacteria have not been identified in every state at this time.The highest rates are in the Northeast, Upper Midwest, and parts of Northern California and the Pacific Northwest.How Is Lyme disease transmitted?Ticks pick up the Lyme bacteria by feeding on infected animals, such as mice or birds. When an infected tick bites a person, the bacteria can be transmitted through the tick’s saliva.Ticks go through three life stages: larva, nymph and adult. Nymphs, which are roughly the size of a poppy seed, cause most human infections because they are easy to miss and active in warmer months when people are more often outdoors.How long a tick must be attached to a person’s skin before it transmits disease can vary. One European study documented six cases of confirmed Lyme disease in which tick attachment lasted less than six hours and nine more where transmission occurred in less than 24 hours.While it can take 24 to 36 hours for the bacteria to travel from the tick’s midgut to its salivary glands, transmission can start immediately in an estimated 10% of infected ticks that already carry bacteria in their saliva (due to having taken a partial blood meal before detaching and reattaching to a new host). Removing ticks promptly, ideally before they attach, is thus one of the best ways to prevent infection.What are the symptoms of Lyme disease?Symptoms can vary from mild to severe and may appear days, weeks or even months after the tick bite. Not everyone notices a tick or remembers being bitten. Symptoms vary from person to person and can be intermittent or changing and overlap across different stages, which makes diagnosis more confusing. Potential symptoms include but are not limited to:Early localized disease (days to weeks after infection):Expanding rash, sometimes with a bull’s-eye appearance (erythema migrans) — Importantly, a classic bullseye appearance with central clearing of the rash occurs in a minority of U.S. patients (about 20% reported in one study), although up to 80% of patients may have a rash of varying shapes Fatigue Fever and chills Headache Muscle and joint aches Swollen lymph nodes Early disseminated disease (weeks to months after infection):Multiple rashes on the body Facial weakness or paralysis, usually on one side but can be both (Bell’s palsy) Severe headaches and neck stiffness Pain, tingling or numbness in the arms or legs Cardiac problems, most commonly conduction disturbances (“heart block”) but also a variety of rhythm disturbances, pericarditis or myocarditis Late disease (months to years after infection):Joint swelling or pain, typically in a single or a few large joints such as the knee Neurological problems, such as numbness, tingling, vision/hearing problems or cognitive/memory issues. Reported across all stages of disease:Neuropsychiatric or behavioral manifestations (mood swings, anxiety, depression) Presumed dysautonomia symptoms, such as dizziness, lightheadedness, increased heart rate when standing, and temperature regulation issues, have also been described. Some people never develop the classic rash or other early symptoms, or these signs go unrecognized, so they first present with early disseminated or late-stage symptoms. Why is Lyme disease sometimes missed?Lyme disease is sometimes called “the great imitator” because its symptoms resemble those of other conditions such as flu, chronic fatigue syndrome or autoimmune disorders. Diagnosis is based on a combination of symptoms, possible tick exposure and lab tests.The standard blood tests detect antibodies to Lyme bacteria and not the infection itself. Therefore, these tests may not show a positive result in people with early infection, as their bodies have not yet produced enough antibodies. Importantly, it can also fail to detect later-stage disease, contributing to many missed diagnoses. For this reason, doctors rely on symptoms and exposure history in addition to lab tests when making a clinical diagnosis.How can you prevent Lyme disease?The best way to avoid Lyme disease is to prevent tick bites. Here’s how:Use U.S. Environmental Protection Agency-registered insect repellents containing DEET, picaridin or IR3535. Treat clothing and gear with permethrin. Wear long sleeves, long pants and closed shoes when in grassy or wooded areas. Tuck pants into socks to block ticks from crawling up legs. Stay in the center of trails and avoid tall grass or leaf litter. Check your body, clothing, gear and pets for ticks after outdoor activities. Shower within two hours of coming indoors to help remove ticks before they attach. If you find an attached tick, remove it promptly with fine-tipped tweezers, grasping it close to the skin and pulling straight out.Once removed, consider sending the tick for testing to determine what pathogens it may be carrying. This will give you a good gauge of what to look out for.Of note, if the tick is carrying pathogens, it does not necessarily mean they were passed to you, and if the tick is not carrying pathogens, you should still consider that it is possible you were bitten by another tick that went unnoticed.How Is Lyme disease treated?Early Lyme disease is typically treated with oral antibiotics, such as doxycycline, amoxicillin or cefuroxime. The Infectious Diseases Society of America (IDSA) and CDC recommend 10 to 14 days of antibiotics for early-stage Lyme disease with the caveat that regimens “may need to be adjusted depending on factors such as age, medical history, underlying health conditions, pregnancy status or allergies.” The International Lyme and Associated Diseases Society (ILADS), recommends four to six weeks of antibiotics, with the duration tailored to the patient’s response and clinical circumstances; ILADS guidelines also state that, when necessary, antibiotic therapy should be extended. Patients with certain neurological or cardiac forms of illness may require intravenous treatment with drugs such as ceftriaxone or penicillin.  More advanced neurological or joint disease sometimes requires treatment with longer and more complex regimens or IV antibiotics. Many people can recover fully with prompt treatment, but some continue to experience symptoms for months or years after finishing antibiotics.What about lingering symptoms?Persistent symptoms after treatment, sometimes called persistent Lyme disease (PLD) or Post Treatment Lyme Disease Syndrome (PTLDS), can include, but are not limited to, fatigue, pain and cognitive difficulties. The cause is debated. The possibility of unidentified coinfections contributing to lingering symptoms should be excluded with testing. Additional hypotheses for the cause of persistent symptoms include incompletely eradicated Lyme bacteria, lingering immune responses (autoimmunity), residual tissue damage and other complicating factors acting individually or in combination.Scientific studies funded by Bay Area Lyme Foundation have shown that Lyme infection can persist post-treatment due to Lyme bacteria that are not completely eradicated.On the horizon: Next steps in researchResearchers across the country, including teams supported by Bay Area Lyme Foundation and its affiliates, are working to close critical gaps in Lyme disease prevention, diagnosis and treatment.Current priorities include creating more sensitive and specific diagnostic tests that not only better detect infection early on but also improve recognition of past and late-stage disease, distinguish active from past infections, and confirm when treatment has been successful.Efforts are also underway to identify new therapeutic options for patients with persistent symptoms, to explore vaccines, develop novel prevention tools, and to deepen scientific understanding of Lyme bacteria and the immune system’s response to it.How Bay Area Lyme Foundation is powering progressBay Area Lyme Foundation funds innovative research and fosters collaboration among scientists, clinicians and public health experts to accelerate solutions for Lyme disease.The Foundation’s initiatives include supporting the development of next-generation diagnostics and advancing potential new treatments. It is the founding/operating Lyme Disease Biobank, a vital resource of well-characterized biological samples — including donated blood, urine and tissue  — for researchers worldwide.With its mission to make Lyme disease easy to diagnose and simple to cure, Bay Area Lyme Foundation is committed to reducing the impact of Lyme and other tick-borne diseases for patients everywhere.The bottom lineLyme disease is common, but with awareness, early diagnosis and effective treatment, most people recover fully.To reduce the burden of the disease and help those with persistent symptoms, continued research into new, more accurate diagnostics and improved treatments is essential.Prevention is key: Protect yourself against tick bites, check for ticks after being outdoors, and seek medical care promptly if you develop symptoms.Charlotte Mao, MD, MPH, Bay Area Lyme Foundation, is a pediatric infectious diseases physician whose area of clinical focus is Lyme disease and associated infections.

Climate activists gather in New York for ‘Sun Day’ solar energy and anti-billionaire rallies

Sun Day national action supported renewable energy, day after ‘Make Billionaires Pay’ march ahead of Climate WeekHundreds of environmentalists gathered in New York City’s Stuyvesant Square Park and a nearby Quaker meeting house on Sunday to rally in support of solar power and other forms of renewable energy. The event was part of a national “day of action” billed Sun Day, founded by veteran environmental activist Bill McKibben and first Earth Day coordinator Denis Hayes.“It’s so sad to watch the sun going to waste,” McKibben said at a press conference, standing beside environmentalists and their children. “Every single day, energy from heaven going to waste while we drill down to hell for another dose of the stuff that is wrecking this planet.” Continue reading...

Hundreds of environmentalists gathered in New York City’s Stuyvesant Square Park and a nearby Quaker meeting house on Sunday to rally in support of solar power and other forms of renewable energy. The event was part of a national “day of action” billed Sun Day, founded by veteran environmental activist Bill McKibben and first Earth Day coordinator Denis Hayes.“It’s so sad to watch the sun going to waste,” McKibben said at a press conference, standing beside environmentalists and their children. “Every single day, energy from heaven going to waste while we drill down to hell for another dose of the stuff that is wrecking this planet.”McKibben was joined at the press conference by other activists, as well as officials from New York and his home state of Vermont.“We have the ability here to protect our children, to protect our future,” said New York’s lieutenant governor, Antonio Delgado.The event in the park followed an all-afternoon celebration of clean power, with displays of solar panels, child-friendly lessons on renewable technology, and panel discussions. One popular panel featured McKibben and New York City’s comptroller, Brad Lander.In other parts of the country, activists held more than 500 other actions meant to highlight the creative ways Americans are ditching fossil-based energy. In Virginia, volunteers climbed rooftops to install solar panels on affordable homes built by Habitat for Humanity. In North Carolina, families gathered at a farm powered by solar panels. And in Michigan, organizers held a car show to show off electric vehicles; families also held a beach clean up nearby.Renewable energy sources have seen unprecedented growth in recent years. Last year, they accounted for over 90% of total energy expansion globally, one analysis found. And the US generated less than half of its energy from fossil fuels for the first time this past March.Yet the day of action came amid unprecedented attacks on climate protections and the renewable energy transition by the Trump administration. Since January, his administration has rolled back grants for solar, kicked off an all-of-government approach to shut down wind, halted and delayed wind projects, and launched more than 150 other anti-environmental and anti-renewable energy actions. The plans are threatening not only the climate but also Americans’ pocketbooks, said Vermont senator Peter Welch.“Clean energy is really good for affordability. It lowers the utility bills people are struggling to pay and creates really good jobs,” Welch said in an interview. “What Trump is doing is wrecking that economic potential. Customers are going to get hammered.”Despite these attacks, the event had an overall air of optimism. McKibben said though the US is backsliding on climate progress, much of the rest of the world is continuing to build out renewable power.“The pattern around the world is unmistakable,” he said in an interview. “The reason that it’s happening is partly because of the climate crisis but also largely because this is the cheapest form of energy, and it’s getting cheaper every year.”The Sun Day action came ahead of Climate Week in New York City, an annual event that convenes government officials, corporate actors and activists for a vast array of climate-focused events. It also came one day after the “Make Billionaires Pay” march, for which 25,000 people took to the streets in New York City.“Billionaires caused the climate chaos, spearheaded the rise of authoritarianism and they continue to profit from our suffering. But they forgot one thing: there are more of us than there are of them,” said Renata Pumarol, an organizer with the environmental justice non-profit Climate Defenders, in a statement about the Saturday protest.Sun Day participants did not shy away from naming the fossil fuel companies who have been the primary cause of global warming. But it focused largely on solutions aimed at taking on the climate crisis instead of the actors behind it.McKibben, for instance, praised Utah’s move three months ago to legalize the installation of solar panels on balconies – something that is illegal in all other US states. And New York assemblymember Emily Gallagher previewed a state bill she will introduce next week aimed at helping renters access solar panels.At the press conference, McKibben noted that though the forecast for Sunday showed cloudy skies, the day was bright and warm.“The collective power of all of us is enough to bring out the sun,” he said.

Gatwick second runway plan approved by transport secretary

There has been strong opposition against the airport wanting to use its northern runway.

Gatwick second runway plan approved by transport secretaryKaty Austintransport correspondent andJamie WhiteheadPA MediaTransport Secretary Heidi Alexander has approved plans for a second runway at London Gatwick Airport, as the government looks for economic growth opportunities. The £2.2bn privately-financed project involves in effect moving the current Northern Runway 12 metres to bring it into regular use, as well as other developments, including extending the size of terminals. Chancellor Rachel Reeves said the plans would create "thousands of jobs and billions in investment", but the project has long faced opposition and the Green Party described it as "disaster".Gatwick currently handles about 280,000 flights a year. It says the plan would enable that number to rise to around 389,000 by the late 2030s.Reeves said the second Gatwick runway was part of the government's plan to "get Britain building again".A government source has described the plans as a "no-brainer for growth," adding that "it is possible that planes could be taking off from a new full runway at Gatwick before the next general election."London Gatwick, in West Sussex, is currently Europe's busiest single-runway airport with more than 40 million passengers using it every year. The plans approved by Ms Alexander would include adding 40,000 more flights before the second runway opens, and 70,000 more - almost 190 a day - once it is fully up and running.The airport says that passenger numbers could rise to up to 80 million.Currently, the Northern Runway is currently only used for taxiing or as a back up. The second runway would be used for short haul flights, with capacity also freed up for more long-haul services from the main runway.The decision to approve the expansion plan had been expected in February, but at the time, the transport secretary only said she was "minded to grant consent" for the Northern Runway planning application. It emerged planning inspectors had expressed concerns over the effect the proposals would have on several aspects on the area surrounding the airport, including traffic and noise.In April, Gatwick Airport agreed to stricter noise controls, an enhanced insulation scheme for nearby residents, and having 54% of air passengers using public transport before the Northern Runway opened. To achieve this target, the airport said, third parties - including the Department for Transport - would need to "support delivery of the necessary conditions and improvements required to meet this target," giving the example of reinstating the full Gatwick Express rail service. Before the Covid-19 pandemic, the Gatwick Express ran a service of four trains per hour non-stop between the airport and London Victoria, this was reduced to two trains per hour from 2022. Gatwick Airport also proposed a cars-on-the-road limit if the 54% target could not be met before the first use of the Northern Runway to address possible road congestion concerns. It added that if neither the target nor the cars-on-the road limit could be met, the runway plans would be delayed until the required £350m of road improvements had been completed. "This would make sure any additional road traffic flows can be accommodated and any congestion avoided," the airport said. "This government has taken unprecedented steps to get this done, navigating a needlessly complex planning system, which our reforms will simplify in future," the government source said. "Any airport expansion must be delivered in line with our legally binding climate change commitments and meet strict environmental requirements."Chris Curtis, who chairs the Labour Party's growth group, welcomed the approval but said "radical planning reform" was needed to enable future projects to be completed more swiftly. Shadow transport secretary Richard Holden welcomed the decision as "a vital step towards driving economic growth". But he said approval should have been made months ago and accused Labour of creating "uncertainty for businesses and local communities". But there is strong opposition to any expansion, particularly from climate campaigners.Green Party leader Zack Polanski said approval of the expansion plan was a "disaster for the climate crisis".Hannah Lawrence, spokesperson for Stay Grounded, said "We need an immediate end to airport expansion and money put into improving sustainable transport such as trains."In February, Greenpeace UK policy director Douglas Parr said the extension would not drive economic growth. "The only thing it's set to boost is air pollution, noise, and climate emissions," he added.Alex Chapman, senior economist at left-of-centre think tank New Economics Foundation, also argued the move would not create new jobs, but would just shift them from other parts of the country."People are already perfectly able to catch cheap flights on holiday or travel for business," he added.Unite the Union general secretary Sharon Graham backed Gatwick having a second runway, but warned it would need "to come with guarantees of well paid, unionised jobs and proper facilities for workers".Sally Pavey, chair of Communities Against Gatwick Noise Emissions (CAGNE), said she was worried about "uncontrollable noise, ramifications on the roads, decline in air quality... and climate change"."We can't keep ignoring climate change and it would be wrong to allow a new 'bucket and spade' runway, as we put it, at the expense of residents and the economy," she said.The group would take legal action through a judicial review if the expansion goes ahead, she added.Gatwick's is the latest in a string of airport expansion approvals, most recently Luton's in June. The government has also expressed support for a third runway at the country's biggest airport, Heathrow, but that would be a much more complex, costly and controversial project.

Cuts to Rhode Island energy-efficiency plan bad for residents, study says

Funding for Rhode Island’s energy-efficiency programs could be cut by more than $42 million next year in an effort to rein in residents’ soaring power bills.

Funding for Rhode Island’s energy-efficiency programs could be cut by more than $42 million next year in an effort to rein in residents’ soaring power bills. That rollback would deprive the state of more than $90 million in benefits and potentially eliminate hundreds of jobs while creating only modest up-front savings, a new analysis finds. Rhode Island Energy, the utility that administers the state’s energy-efficiency offerings, has proposed to slash spending on that front by 18% compared to last year and more than 30% compared to the budget originally projected in the nonbinding three-year plan introduced in 2023. If approved, the cuts will save the average household $1.87 per month, according to Rhode Island Energy. The result of these changes, according to climate action nonprofit Acadia Center, would be more expensive electricity and more exposure to volatile natural gas prices in the long run. “Energy efficiency is a tool for suppressing supply costs, for suppressing infrastructure costs in the long-term,” said Emily Koo, Acadia Center’s program director for Rhode Island and one of the authors of the group’s analysis. ​“I am not seeing our leaders think beyond the immediate.” Rhode Island has traditionally been a leader in energy-efficiency programming. Over the past 15 years, the state has repeatedly placed among the top 10 states in the American Council for an Energy-Efficient Economy’s annual energy-efficiency scorecard. Since 2009, the state has spent more than $2 billion on efficiency incentives and services, yielding more than $6 billion in environmental and social benefits. Now, however, the dynamics of energy markets are creating new obstacles. Nationwide, electricity costs have gone up at twice the rate of inflation over the past year, and gas prices have increased by more than four times the inflation rate. Rhode Island, like other New England states, has the added difficulty of already having some of the highest electricity rates in the country. Add in cold Northeastern winters, and the state is girding for an expensive season ahead. As in neighboring states, regulators, elected officials, and utilities in Rhode Island are scrambling for ways to provide some relief for residents and businesses. These efforts have increasingly looked to the bill fees that fund renewable energy incentives and energy-efficiency programs as possible targets for quick, if small, bill reductions. In Maine, for example, leaders from both sides of the aisle have sought to lower incentives for customers and community solar developments that send power back to the grid, and in Massachusetts, utility regulators ordered energy-efficiency administrators to cut $500 million from a planned $5 billion three-year budget. Now, Rhode Island Energy is proposing rollbacks of its own, saying that its latest plan prioritizes customer affordability. The company has the support of the Rhode Island Division of Public Utilities and Carriers, which points to the growth in accounts with overdue utility bills to bolster its argument that the changes will provide needed relief to consumers. “There is simply a financial limit as to how much cost the ratepayers can bear,” the department wrote in its public comments on the proposal.

The Dark Matter of Food: Why Most of Nutrition Remains a Mystery

What we eat is packed with hidden chemistry that may hold the key to both disease and health.

Food is far more than calories and nutrients, it’s a chemical universe we’ve barely begun to map. Unlocking this “nutritional dark matter” could transform our understanding of health and disease. Credit: ShutterstockWhat we eat is packed with hidden chemistry that may hold the key to both disease and health. When the human genome was first sequenced in 2003, many believed this breakthrough would reveal the full origins of disease. Yet, genetics accounts for only about 10% of overall risk. The remaining 90% is shaped by environmental factors, with diet playing a particularly significant role. Globally, poor nutrition is estimated to contribute to roughly one in five deaths among adults over the age of 25. In Europe, dietary factors alone are responsible for nearly half of all cardiovascular fatalities. Despite decades of public health campaigns urging people to reduce fat, salt, and sugar, obesity rates and diet-related diseases have continued to climb. Clearly, something is missing from the way we think about food. Beyond calories and nutrients For much of modern history, nutrition has been described in simplified terms, viewing food primarily as fuel and nutrients as the building blocks of the body. Attention has focused on about 150 well-known chemicals such as proteins, fats, carbohydrates, and vitamins. However, researchers now believe that the human diet actually contains more than 26,000 distinct compounds, the majority of which remain largely unexplored. Here is where astronomy provides a useful comparison. Astronomers know that dark matter makes up about 27% of the universe. It doesn’t emit or reflect light, and so it cannot be seen directly but its gravitational effects reveal that it must exist. Nutrition science faces something similar. The vast majority of chemicals in food are invisible to us in terms of research. We consume them every day, but we have little idea what they do. Some experts refer to these unknown molecules as “nutritional dark matter.” It’s a reminder that just as the cosmos is filled with hidden forces, our diet is packed with hidden chemistry. When researchers analyze disease, they look at a vast array of foods, although any association often cannot be matched to known molecules. This is the dark matter of nutrition – the compounds we ingest daily but haven’t been mapped or studied. Some may encourage health, but others may increase the risk of disease. The challenge is finding out which do what. Foodomics as a new approach The field of foodomics aims to do exactly that. It brings together genomics (the role of genes), proteomics (proteins), metabolomics (cell activity) and nutrigenomics (the interaction of genes and diet). These approaches are starting to reveal how diet interacts with the body in ways far beyond calories and vitamins. Take the Mediterranean diet (filled with fruits, vegetables, whole grains, legumes, nuts, olive oil, and fish, with limited red meat and sweets), for example, which is known to reduce the risk of heart disease. But why does it work? One clue lies in a molecule called TMAO (trimethylamine N-oxide), produced when gut bacteria metabolize compounds in red meat and eggs. High levels of TMAO increase the risk of heart disease. But garlic, for example, contains substances that block its production. This is one example of how diet can tip the balance between health and harm. Gut microbes and food chemistry Gut bacteria also play a major role. When compounds reach the colon, microbes transform them into new chemicals that can affect inflammation, immunity and metabolism. For example, ellagic acid – found in various fruits and nuts – is converted by gut bacteria into urolithins. These are a group of natural compounds that help keep our mitochondria (the body’s energy factories) healthy. This shows how food is a complex web of interacting chemicals. One compound can influence many biological mechanisms, which in turn can affect many others. Diet can even switch genes on or off through epigenetics – changes in gene activity that don’t alter DNA itself. History has provided stark examples of this. For example, children born to mothers who endured famine in the Netherlands during the Second World War were more likely to develop heart disease, type 2 diabetes, and schizophrenia later in life. Decades on, scientists found their gene activity had been altered by what their mothers ate – or didn’t eat – while pregnant. Mapping the hidden food universe Projects such as the Foodome Project are now attempting to catalogue this hidden chemical universe. More than 130,000 molecules have already been listed, linking food compounds to human proteins, gut microbes and disease processes. The aim is to build an atlas of how diet interacts with the body, and to pinpoint which molecules really matter for health. The hope is that by understanding nutritional dark matter, we can answer questions that have long frustrated nutrition science. Why do certain diets work for some people but not others? Why do foods sometimes prevent, and sometimes promote, disease? Which food molecules could be harnessed to develop new drugs, or new foods? We are still at the beginning. But the message is clear – the food on our plate is not just calories and nutrients, but a vast chemical landscape we are only starting to chart. Just as mapping cosmic dark matter is transforming our view of the universe, uncovering nutritional dark matter could transform how we eat, how we treat disease and how we understand health itself.

Hundreds plunge in Chicago River for first official swim in nearly 100 years

Hundreds of people plunged into the Chicago River’s chilly waters on Sunday as part of the first organized swim in the river for nearly 100 years, a previously unthinkable act in what was once one of the most befouled waterways in the world.About 300 people, some wearing wetsuits, jumped into the Chicago River for a mile-long looping swim on an early, overcast midwest morning, a feat made possible by the often unseen but crucial progress the US has made in the past half century in cleaning its rivers of toxic pollution.“It’s overwhelming to see this happen, it’s unbelievable to see swimmers swim past us now,” said Doug McConnell, the main organizer of the event.McConnell, a Chicago area native and co-founder of A Long Swim, had been pushing the city’s leadership for more than a decade to allow a swim in the river, the first such event since 1927, having witnessed the blossoming urban river swimming movement take hold in cities such as Paris, Munich and Amsterdam.“Seeing that really planted a seed, and we are thrilled we are finally doing this and that it has got global attention – we had applications across the US and 13 countries,” said McConnell, who hopes this will become an annual event and spread to other US cities.McConnell didn’t leap into the water on Sunday but is an accomplished long-distance swimmer, having traversed the English Channel, which he recalls as “14 hours of getting slapped around”, and swam around the island of Manhattan, all in aid of amyotrophic lateral sclerosis (ALS) fundraising.“I think the water conditions will surprise people because it will be cleaner than they expect,” he said. “The psychology of so many Chicagoans was that the river is untouchable – this isn’t true and we are proving this today.“My grandfather grew up in Chicago and I think what his reaction to all of this would be because the river had an absolutely toxic reputation then. It was repulsive, absolutely untouchable.”The Chicago River has a long history of being meddled with. Each year it is dyed green for St Patrick’s Day and, infamously, in 2004 the tour bus of Dave Matthews Band released 800lbs (363kg) of human waste through a bridge grate that landed on top of a boat of mightily unfortunate sightseers traveling on the river.Indeed, Chicago initially grew by treating its slow-moving river as an unfettered dumping area. Sewage and other waste was routinely funneled into the river, including carcasses and effluent from huge slaughterhouses that clustered beside the waterway – to the extent that a section of the river is still called “bubble creek” due to the gas given off by the rotting sludge on the riverbed.The river became so foul, causing deadly outbreaks of cholera and typhoid, that the city took the extraordinary step in 1900 of reversing the river’s flow by creating a system of canals and locks, to avoid Chicago’s source of drinking water in Lake Michigan becoming poisoned. Today, the 156-mile (265km) river meanders from Lake Michigan through Chicago so its water ultimately empties into the Gulf of Mexico.“We treated the river like it was part of the sewer system, which haunted us,” said Margaret Frisbie, the executive director of Friends of the Chicago River. Riverside buildings typically didn’t even have windows overlooking what was known as “the stinking river”, with the ribbon of water shunned as part of Chicago’s civic fabric.“Until just a few years ago people would’ve thought it would be outrageous to jump into it,” Frisbie said. When Friends of the Chicago River formed in 1979 with a vision to restore the ecological function of a river that could be enjoyed by people and wildlife alike, “people thought we were crazy,” she said.Yet the 1970s was a seminal decade for environmental protection in the US, with the passage of the Clean Water Act and the creation of the Environmental Protection Agency (EPA) – bringing new restrictions on pollution dumped into rivers, streams and lakes. Where once American rivers were so toxic they could catch fire, a new era had begun that would allow US cities to think more affectionately of their foundational waterways.In Chicago, the slaughterhouses shut down, new sewage and storm water infrastructure was built and teams of volunteers, as they do to this day, toiled to clean up trash.Dozens of species of fish returned, as did beavers and snapping turtles such as Chonkosaurus, an enormous, locally famous specimen sometimes seen lounging by the river.In 2016, a riverside public pathway was completed to knit the downtown area to its adjacent water, allowing Chicagoans in new bars and restaurants to gaze upon a river that is no longer a fetid soup, a place clean enough that people can now swim in it. On 12 September, it was announced that Friends of the Chicago River won an international prize in recognition of the river’s transformation.“So many people are on rental boats on the river these days – it’s heaving with people,” Frisbie said. “People want to work near the river, live near it, be on it. It’s remarkable to see people have that connection with it again.“This swim is emblematic of all the work we’ve done over the past 50 years to improve our rivers. It shows you can change the destiny of any natural resource and do some good. It feels that’s something we need right now.”America’s rivers may now increasingly be places of scenic recreation rather than industrial sacrifice zones, but this does depend on the vicissitudes of politics. The Trump administration is narrowing the application of the Clean Water Act, which helped ensure healthier rivers, and is similarly weakening rules on what coal plants and factories can dump in waterways. The bad old days may be a thing of the past, but ongoing progress isn’t guaranteed.“If the federal government retreats from enforcement, things could slide backwards,” Frisbie said. “It’s incumbent on cities, countries and states to be vigilant. Our river is beloved now – people want to use it, wildlife needs it, we need it. We want to maintain that rather than see it roll back.”On Sunday, though, few swimmers were mulling such weighty topics as they lined up in robes, serenaded by the skirl of the Chicago police department’s bagpipes and drum, before stripping and vaulting into the river, bobbling flotation devices tethered to their waists.Organizers had zealously tested the water in the weeks before the event, finding that the river was consistently safe in terms of EPA standards on fecal coliform – essentially, poo in the water. The river was scanned, too, for any potential obstructions to the swimmers.Among the participants for the first river swim in 98 years – all strictly vetted to ensure they could complete the course – was Olivia Smoliga, who grew up in the Chicago suburbs and went on to win a gold medal in backstroke at the 2016 Olympic games.Open water swimming is a different beast to the lanes of a pool, but Smoliga’s competitive spirit compelled her to speed around the river loop, even though it was not intended to be a race.“You have people throwing elbows there – you have to watch out for fingernail length, everything,” she said. “The fact they were able to clean up the river and do such great work, to have this full on race happen, is trippy. But it’s really cool.”
