Umbilical Cord Could Contain Clues For Child's Future Health

By Dennis Thompson HealthDay ReporterFRIDAY, April 25, 2025 (HealthDay News) -- Doctors might be able to predict a newborn's long-term health outlook, by analyzing their umbilical cord blood, a new study says.Genetic clues found in cord blood can offer early insight into which infants are at higher risk for health problems like diabetes, stroke and liver disease later in life, researchers will report at the upcoming Digestive Disease Week meeting in San Diego.“We’re seeing kids develop metabolic problems earlier and earlier, which puts them at higher risk for serious complications as adults,” lead researcher Dr. Ashley Jowell, a resident physician in internal medicine at Duke University Health System in Durham, N.C., said in a news release. “If we can identify that risk at birth, we may be able to prevent it.”For the study, researchers performed genetic analysis on the umbilical cord blood of 38 children enrolled in a long-term study based in North Carolina.The analysis looked for chemical patterns in infants’ DNA that switch genes on or off. When these switches occur in critical parts of DNA, their health effects can persist through fetal development and into later life.The research team compared these DNA changes to the kids’ health at ages 7 to 12, and identified multiple areas where genes in cord blood predicted health problems in childhood.For example, changes in a gene called TNS3 were linked to fatty liver, liver inflammation or damage, and excess belly fat as measured by waist-to-hip ratio, results show.Changes in other genes were connected to blood pressure, waist-to-hip ratio, and liver inflammation or damage, researchers said.“These epigenetic signals are laid down during embryonic development, potentially influenced by environmental factors such as nutrition or maternal health during pregnancy,” co-researcher Dr. Cynthia Moylan, an associate professor in the division of gastroenterology at Duke University Health System, said in a news release.Researchers noted that the sample size was small, but the links so powerful that these findings warrant further investigation. A larger follow-up study funded by the National Institutes of Health is underway.“If validated in larger studies, this could open the door to new screening tools and early interventions for at-risk children,” Moylan added.Jowell said disease may be preventable even with these markers."Just because you're born with these markers doesn't mean disease is inevitable," she said. "But knowing your risk earlier in life could help families and clinicians take proactive steps to support a child’s long-term health."Researchers are scheduled to present their findings May 4. Findings presented at medical meetings are considered preliminary until published in a peer-reviewed journal.SOURCE: American Gastroenterological Association, news release, April 25, 2025Copyright © 2025 HealthDay.

Hundreds of life-size animal puppets have begun a 20,000km (12,400 mile) journey from central Africa to the Arctic Circle as part of an ambitious project created by the team behind Little Amal, the giant puppet of a Syrian girl that travelled across the world.The public art initiative called The Herds, which has already visited Kinshasa and Lagos, will travel to 20 cities over four months to raise awareness of the climate crisis.It is the second major project from The Walk Productions, which introduced Little Amal, a 12-foot puppet, to the world in Gaziantep, near the Turkey-Syria border, in 2021. The award-winning project, co-founded by the Palestinian playwright and director Amir Nizar Zuabi, reached 2 million people in 17 countries as she travelled from Turkey to the UK.The Herds’ journey began in Kinshasa’s Botanical Gardens on 10 April, kicking off four days of events. It moved on to Lagos, Nigeria, the following week, where up to 5,000 people attended events performed by more than 60 puppeteers.On Friday the streets of Dakar in Senegal will be filled with more than 40 puppet zebras, wildebeest, monkeys, giraffes and baboons as they run through Médina, one of the busiest neighbourhoods, where they will encounter a creation by Fabrice Monteiro, a Belgium-born artist who lives in Senegal, and is known for his large-scale sculptures. On Saturday the puppets will be part of an event in the fishing village of Ngor.The Herds’ 20,000km journey began in Kinshasa, the Democratic Republic of the Congo.

The project has already attracted huge interest from people keen to get involved. In Dakar more than 300 artists applied for 80 roles as artists and puppet guides. About 2,000 people will be trained to make the puppets over the duration of the project.“The idea is that we’re migrating with an ever-evolving, growing group of animals,” Zuabi told the Guardian last year.Zuabi has spoken of The Herds as a continuation of Little Amal’s journey, which was inspired by refugees, who often cite climate disaster as a trigger for forced migration. The Herds will put the environmental emergency centre stage, and will encourage communities to launch their own events to discuss the significance of the project and get involved in climate activism.The puppets are created with recycled materials and local volunteers are taught how to make them in each location.

As soon as the project started, when people were shown pictures of the puppets, they were going crazy.”Little Amal, the puppet of a Syrian girl that has become a symbol of human rights, in Santiago, Chile on 3 January.

UK spending watchdog censures water firms and regulators over sewage failings

NAO finds regulatory gaps have enabled overspending on infrastructure building while not improving sewage worksWater companies have been getting away with failures to improve sewage works and overspending because of regulatory problems, a damning report by the government’s spending watchdog has found.Firms have overspent on infrastructure building, the National Audit Office (NAO) found, with some of these costs being added to consumers’ bills.

Water companies have been getting away with failures to improve sewage works and overspending because of regulatory problems, a damning report by the government’s spending watchdog has found.Firms have overspent on infrastructure building, the National Audit Office (NAO) found, with some of these costs being added to consumers’ bills. The Guardian this week reported Ofwat and the independent water commission are investigating water firms for spending up to 10 times as much on their sewage works and piping as comparable countries.Bills in England and Wales are rising by £123 on average this year, and will go up further over the next five years, so that companies can fix ageing sewage infrastructure and stop spills of human waste from contaminating rivers and seas. Several water firms have complained to the Competition and Markets Authority because they want the regulator to allow them to increase bills even further.Only 1% of water companies’ actions to improve environmental performance, such as improving sewer overflows, have been inspected by the Environment Agency, the authors of the NAO report said. They also found there was no regulator responsible for proactively inspecting wastewater assets to prevent further environmental harm.The report, which audited the three water regulators, Ofwat, the Environment Agency, and the Drinking Water Inspectorate, as well as the Department for Environment Food and Rural Affairs, also found the regulators did not have a good understanding of the condition of infrastructure assets such as leaking sewers and ageing sewage treatment facilities as they do not have a set of metrics to assess their condition.Gareth Davies, the head of the NAO, said: “Given the unprecedented situation facing the sector, Defra and the regulators need to act urgently to address industry performance and resilience to ensure the sector can meet government targets and achieve value for money over the long term for bill payers.”Despite the huge costs of infrastructure, the water companies have moved slowly meaning that at the current rate, it would take 700 years to replace the entire existing water network, the report found. Regulatory gaps and a lack of urgency about replacing old and malfunctioning infrastructure has caused a “rising tide of risk” in the sector, which is contributing to increasing bills for customers, the report warned.It also criticised the lack of a national plan for water supply and recommended that Defra must understand the costs and deliverability of its plans, alongside the impact they would have on customers’ bills.Several of the issues raised by the NAO, including concerns about weak infrastructure, have come to the fore in the debate over the future of Thames Water, the country’s largest water company with 16 million customers. Thames, which is under significant financial pressure with almost £20bn in debt, needs to secure fresh investment within months. Questions over the state of Thames’s infrastructure and regulatory punishment it could face for its failures have dogged the process of winning fresh funds. Meanwhile, Ofwat has also rejected its requests to raise bills by as much as 59%, instead allowing a 35% increase over the next five years.The government set up the independent water commission (IWC) last year to investigate how the water industry operated and whether regulation was fit for purpose.Sir Geoffrey Clifton-Brown, the Tory chair of the Commons public accounts committee, said: “Today’s NAO report lays bare the scale of the challenges facing the water sector – not least the real prospect of water shortfall without urgent action.“The consequences of government’s failure to regulate this sector properly are now landing squarely on bill payers who are being left to pick up the tab. After years of under-investment, pollution incidents and water supply issues, it is no surprise that consumer trust is at an all-time low.

Defra and the regulators must focus on rebuilding public confidence and ensure the sector can attract the long-term investment it desperately needs.”An Environment Agency spokesperson said: “We recognise the significant challenges facing the water industry. That is why we will be working with Defra and other water regulators to implement the report’s recommendations and update our frameworks to reflect its findings.”An Ofwat spokesperson added: “We agree with the NAO’s recommendations for Ofwat and we continue to progress our work in these areas, and to contribute to the IWC wider review of the regulatory framework. We also look forward to the IWC’s recommendations and to working with government and other regulators to better deliver for customers and the environment.”A Defra spokesperson said: “The government has taken urgent action to fix the water industry – but change will not happen overnight. We have put water companies under tough special measures through our landmark Water Act.”Water UK, which represents the water companies, has been contacted for comment.

Only three people prosecuted for covering up illegal sewage spills

Employees of water firms who obstruct investigations into spills could face jail, as new rules come into force on FridayWater company bosses have entirely escaped punishment for covering up illegal sewage spills, government figures show, as ministers prepare to bring in a new law threatening them with up to two years in prison for doing so.Only three people have ever been prosecuted for obstructing the Environment Agency in its investigations into sewage spills, officials said, with none of them receiving even a fine.

Water company bosses have entirely escaped punishment for covering up illegal sewage spills, government figures show, as ministers prepare to bring in a new law threatening them with up to two years in prison for doing so.Only three people have ever been prosecuted for obstructing the Environment Agency in its investigations into sewage spills, officials said, with none of them receiving even a fine.Officials said the data shows why the water regulator has found it so difficult to stop illegal spills, which happen when companies dump raw sewage during dry weather. The Environment Agency has identified hundreds of such cases since 2020.Steve Reed, the environment secretary, said: “Bosses must face consequences if they commit crimes – there must be accountability. From today, there will be no more hiding places.“Water companies must now focus on cleaning up our rivers, lakes and seas for good.”Water companies dumped a record amount of sewage into rivers and coastal waters last year, mostly because wet weather threatened to wash sewage back into people’s homes.Data released last month by the Environment Agency revealed companies had discharged untreated effluent for nearly 4m hours during 2024, a slight increase on the previous year.But companies have also illegally dumped sewage during dry weather. Data released to the Telegraph last year under freedom of information rules shows regulators had identified 465 illegal sewage spills since 2020, with a further 154 under investigation as potentially illegal spills.Britain’s polluted waterways became a major issue at last year’s election, with Labour promising to end what it called the “Tory sewage scandal”.Government sources say one reason illegal spills have been allowed to continue is that regulators have faced obstruction when investigating them.In 2019, three employees at Southern Water were convicted of hampering the Environment Agency when it was trying to collect data as part of an investigation into raw sewage spilled into rivers and on beaches in south-east England.The maximum punishment available in that case was a fine, but none of the individuals were fined. Several of the employees said at the time they were told by the company solicitor not to give data to the regulator.Two years later, Southern was given a £90m fine after pleading guilty to thousands of illegal discharges of sewage over a five-year period.New rules coming into force on Friday will give legal agencies the power to bring prosecutions in the crown court against employees for obstructing regulatory investigations, with a maximum sanction of imprisonment.Directors and executives can be prosecuted if they have consented to or connived with that obstruction, or allowed it to happen through neglect.The rules were included in the Water (Special Measures) Act, which came into law in February. The act also gives the regulator new powers to ban bonuses if environmental standards are not met and requires companies to install real-time monitors at every emergency sewage outlet.Philip Duffy, the chief executive of the Environment Agency, said: “The act was a crucial step in making sure water companies take full responsibility for their impact on the environment.“The tougher powers we have gained through this legislation will allow us, as the regulator, to close the justice gap, deliver swifter enforcement action and ultimately deter illegal activity.“Alongside this, we’re modernising and expanding our approach to water company inspections – and it’s working. More people, powers, better data and inspections are yielding vital evidence so that we can reduce sewage pollution, hold water companies to account and protect the environment.”

Dead, sick pelicans turning up along Oregon coast

So far, no signs of bird flu but wildlife officials continue to test the birds.

Sick and dead pelicans are turning up on Oregon’s coast and state wildlife officials say they don’t yet know why. The Oregon Department of Fish and Wildlife says it has collected several dead brown pelican carcasses for testing. Lab results from two pelicans found in Newport have come back negative for highly pathogenic avian influenza, also known as bird flu, the agency said. Avian influenza was detected in Oregon last fall and earlier this year in both domestic animals and wildlife – but not brown pelicans. Additional test results are pending to determine if another disease or domoic acid toxicity caused by harmful algal blooms may be involved, officials said. In recent months, domoic acid toxicity has sickened or killed dozens of brown pelicans and numerous other wildlife in California. The sport harvest for razor clams is currently closed in Oregon – from Cascade Head to the California border – due to high levels of domoic acid detected last fall.Brown pelicans – easily recognized by their large size, massive bill and brownish plumage – breed in Southern California and migrate north along the Oregon coast in spring. Younger birds sometimes rest on the journey and may just be tired, not sick, officials said. If you find a sick, resting or dead pelican, leave it alone and keep dogs leashed and away from wildlife. State wildlife biologists along the coast are aware of the situation and the public doesn’t need to report sick, resting or dead pelicans. — Gosia Wozniacka covers environmental justice, climate change, the clean energy transition and other environmental issues.

Harris County commissioners approve climate justice plan

Nearly three years in the works, the Harris County Climate Justice Plan is a 59-page document that creates long-term strategies addressing natural resource conservation, infrastructure resiliency and flood control.

Sarah GrunauFlood waters fill southwest Houston streets during Hurricane Beryl on July 8, 2024.Harris County commissioners this month approved what’s considered the county’s most comprehensive climate justice plan to date. Nearly three years in the works, the Harris County Climate Justice Plan is a 59-page document that creates long-term strategies addressing natural resource conservation, infrastructure resiliency and flood control in the Houston area. The climate justice plan was created by the Office of County Administration’s Office of Sustainability and an environmental nonprofit, Coalition for Environment, Equity and Resilience. The plan sets goals in five buckets, said Stefania Tomaskovic, the coalition director for the nonprofit. Those include ecology, infrastructure, economy, community and culture. County officials got feedback from more than 340 residents and organizations to ensure the plans reflect the needs of the community. “We held a number of community meetings to really outline the vision and values for this process and then along the way we’ve integrated more and more community members into the process of helping to identify the major buckets of work,” Tomaskovic told Hello Houston. Feedback from those involved in the planning process of the climate justice plan had a simple message — people want clean air, strong infrastructure in their communities, transparency and the opportunity to live with dignity, according to the plan. It outlines plans to protect from certain risks through preventative floodplain and watershed management, land use regulations and proactive disaster preparation. Infrastructure steps in the plan include investing in generators and solar power battery backup, and expanding coordination of programs that provide rapid direct assistance after disasters. Economic steps in the plan including expanding resources with organizations to support programs that provide food, direct cash assistance and housing. Tomaskovic said the move could be cost effective because some studies show that for every dollar spent on mitigation, you’re actually saving $6. “It can be cost effective but also if you think about, like, the whole line of costs, if we are implementing programs that help keep people out of the emergency room, we could be saving in the long run, too,” she said. Funds that will go into implementing the projects have yet to be seen. The more than $700,000 climate plan was funded by nonprofit organizations, including the Jacob & Terese Hershey Foundation. “Some of them actually are just process improvements,” Lisa Lin, director of sustainability with Harris County, told Hello Houston. “Some of them are actually low-cost, no-cost actions. Some of them are kind of leaning on things that are happening in the community or happening in the county. Some of them might be new and then we’ll be looking at different funding sources.” The county will now be charged with bringing the plan into reality, which includes conducting a benefits and impacts analysis. County staffers will also develop an implementation roadmap to identify specific leaders and partners and a plan to track its success, according to the county. “This initiative is the first time a U.S. county has prepared a resiliency plan that covers its entire population, as opposed to its bureaucracy alone," Harris County Judge Lina Hidalgo said in a statement. "At the heart of this plan are realistic steps to advance issues like clean air, resilient infrastructure, and housing affordability and availability. Many portions of the plan are already in progress, and I look forward to continued advancement over the years."

50-Million-Year-Old Footprints Open a 'Rare Window' Into the Behaviors of Extinct Animals That Once Roamed in Oregon

Scientists revisited tracks made by a shorebird, a lizard, a cat-like predator and some sort of large herbivore at what is now John Day Fossil Beds National Monument

50-Million-Year-Old Footprints Open a ‘Rare Window’ Into the Behaviors of Extinct Animals That Once Roamed in Oregon Scientists revisited tracks made by a shorebird, a lizard, a cat-like predator and some sort of large herbivore at what is now John Day Fossil Beds National Monument Sarah Kuta - Daily Correspondent April 24, 2025 4:59 p.m. Researchers took a closer look at fossilized footprints—including these cat-like tracks—found at John Day Fossil Beds National Monument in Oregon. National Park Service Between 29 million and 50 million years ago, Oregon was teeming with life. Shorebirds searched for food in shallow water, lizards dashed along lake beds and saber-toothed predators prowled the landscape. Now, scientists are learning more about these prehistoric creatures by studying their fossilized footprints. They describe some of these tracks, discovered at John Day Fossil Beds National Monument, in a paper published earlier this year in the journal Palaeontologia Electronica. John Day Fossil Beds National Monument is a nearly 14,000-acre, federally protected area in central and eastern Oregon. It’s a well-known site for “body fossils,” like teeth and bones. But, more recently, paleontologists have been focusing their attention on “trace fossils”—indirect evidence of animals, like worm burrows, footprints, beak marks and impressions of claws. Both are useful for understanding the extinct creatures that once roamed the environment, though they provide different kinds of information about the past. “Body fossils tell us a lot about the structure of an organism, but a trace fossil … tells us a lot about behaviors,” says lead author Conner Bennett, an Earth and environmental scientist at Utah Tech University, to Crystal Ligori, host of Oregon Public Broadcasting’s “All Things Considered.” Oregon's prehistoric shorebirds probed for food the same way modern shorebirds do, according to the researchers. Bennett et al., Palaeontologia Electronica, 2025 For the study, scientists revisited fossilized footprints discovered at the national monument decades ago. Some specimens had sat in museum storage since the 1980s. They analyzed the tracks using a technique known as photogrammetry, which involved taking thousands of photographs to produce 3D models. These models allowed researchers to piece together some long-gone scenes. Small footprints and beak marks were discovered near invertebrate trails, suggesting that ancient shorebirds were pecking around in search of a meal between 39 million and 50 million years ago. This prehistoric behavior is “strikingly similar” to that of today’s shorebirds, according to a statement from the National Park Service. “It’s fascinating,” says Bennett in the statement. “That is an incredibly long time for a species to exhibit the same foraging patterns as its ancestors.” Photogrammetry techniques allowed the researchers to make 3D models of the tracks. Bennett et al., Palaeontologia Electronica, 2025 Researchers also analyzed a footprint with splayed toes and claws. This rare fossil was likely made by a running lizard around 50 million years ago, according to the team. It’s one of the few known reptile tracks in North America from that period. An illustration of a nimravid, an extinct, cat-like predator NPS / Mural by Roger Witter They also found evidence of a cat-like predator dating to roughly 29 million years ago. A set of paw prints, discovered in a layer of volcanic ash, likely belonged to a bobcat-sized, saber-toothed predator resembling a cat—possibly a nimravid of the genus Hoplophoneus. Since researchers didn’t find any claw marks on the paw prints, they suspect the creature had retractable claws, just like modern cats do. A set of three-toed, rounded hoofprints indicate some sort of large herbivore was roaming around 29 million years ago, probably an ancient tapir or rhinoceros ancestor. Together, the fossil tracks open “a rare window into ancient ecosystems,” says study co-author Nicholas Famoso, paleontology program manager at the national monument, in the statement. “They add behavioral context to the body fossils we’ve collected over the years and help us better understand the climate and environmental conditions of prehistoric Oregon,” he adds.

Designing a new way to optimize complex coordinated systems

Using diagrams to represent interactions in multipart systems can provide a faster way to design software improvements.

Coordinating complicated interactive systems, whether it’s the different modes of transportation in a city or the various components that must work together to make an effective and efficient robot, is an increasingly important subject for software designers to tackle. Now, researchers at MIT have developed an entirely new way of approaching these complex problems, using simple diagrams as a tool to reveal better approaches to software optimization in deep-learning models.They say the new method makes addressing these complex tasks so simple that it can be reduced to a drawing that would fit on the back of a napkin.The new approach is described in the journal Transactions of Machine Learning Research, in a paper by incoming doctoral student Vincent Abbott and Professor Gioele Zardini of MIT’s Laboratory for Information and Decision Systems (LIDS).“We designed a new language to talk about these new systems,” Zardini says. This new diagram-based “language” is heavily based on something called category theory, he explains.It all has to do with designing the underlying architecture of computer algorithms — the programs that will actually end up sensing and controlling the various different parts of the system that’s being optimized. “The components are different pieces of an algorithm, and they have to talk to each other, exchange information, but also account for energy usage, memory consumption, and so on.” Such optimizations are notoriously difficult because each change in one part of the system can in turn cause changes in other parts, which can further affect other parts, and so on.The researchers decided to focus on the particular class of deep-learning algorithms, which are currently a hot topic of research. Deep learning is the basis of the large artificial intelligence models, including large language models such as ChatGPT and image-generation models such as Midjourney. These models manipulate data by a “deep” series of matrix multiplications interspersed with other operations. The numbers within matrices are parameters, and are updated during long training runs, allowing for complex patterns to be found. Models consist of billions of parameters, making computation expensive, and hence improved resource usage and optimization invaluable.Diagrams can represent details of the parallelized operations that deep-learning models consist of, revealing the relationships between algorithms and the parallelized graphics processing unit (GPU) hardware they run on, supplied by companies such as NVIDIA. “I’m very excited about this,” says Zardini, because “we seem to have found a language that very nicely describes deep learning algorithms, explicitly representing all the important things, which is the operators you use,” for example the energy consumption, the memory allocation, and any other parameter that you’re trying to optimize for.Much of the progress within deep learning has stemmed from resource efficiency optimizations. The latest DeepSeek model showed that a small team can compete with top models from OpenAI and other major labs by focusing on resource efficiency and the relationship between software and hardware. Typically, in deriving these optimizations, he says, “people need a lot of trial and error to discover new architectures.” For example, a widely used optimization program called FlashAttention took more than four years to develop, he says. But with the new framework they developed, “we can really approach this problem in a more formal way.” And all of this is represented visually in a precisely defined graphical language.But the methods that have been used to find these improvements “are very limited,” he says. “I think this shows that there’s a major gap, in that we don’t have a formal systematic method of relating an algorithm to either its optimal execution, or even really understanding how many resources it will take to run.” But now, with the new diagram-based method they devised, such a system exists.Category theory, which underlies this approach, is a way of mathematically describing the different components of a system and how they interact in a generalized, abstract manner. Different perspectives can be related. For example, mathematical formulas can be related to algorithms that implement them and use resources, or descriptions of systems can be related to robust “monoidal string diagrams.” These visualizations allow you to directly play around and experiment with how the different parts connect and interact. What they developed, he says, amounts to “string diagrams on steroids,” which incorporates many more graphical conventions and many more properties.“Category theory can be thought of as the mathematics of abstraction and composition,” Abbott says. “Any compositional system can be described using category theory, and the relationship between compositional systems can then also be studied.” Algebraic rules that are typically associated with functions can also be represented as diagrams, he says. “Then, a lot of the visual tricks we can do with diagrams, we can relate to algebraic tricks and functions. So, it creates this correspondence between these different systems.”As a result, he says, “this solves a very important problem, which is that we have these deep-learning algorithms, but they’re not clearly understood as mathematical models.” But by representing them as diagrams, it becomes possible to approach them formally and systematically, he says.One thing this enables is a clear visual understanding of the way parallel real-world processes can be represented by parallel processing in multicore computer GPUs. “In this way,” Abbott says, “diagrams can both represent a function, and then reveal how to optimally execute it on a GPU.”The “attention” algorithm is used by deep-learning algorithms that require general, contextual information, and is a key phase of the serialized blocks that constitute large language models such as ChatGPT. FlashAttention is an optimization that took years to develop, but resulted in a sixfold improvement in the speed of attention algorithms.Applying their method to the well-established FlashAttention algorithm, Zardini says that “here we are able to derive it, literally, on a napkin.” He then adds, “OK, maybe it’s a large napkin.” But to drive home the point about how much their new approach can simplify dealing with these complex algorithms, they titled their formal research paper on the work “FlashAttention on a Napkin.”This method, Abbott says, “allows for optimization to be really quickly derived, in contrast to prevailing methods.” While they initially applied this approach to the already existing FlashAttention algorithm, thus verifying its effectiveness, “we hope to now use this language to automate the detection of improvements,” says Zardini, who in addition to being a principal investigator in LIDS, is the Rudge and Nancy Allen Assistant Professor of Civil and Environmental Engineering, and an affiliate faculty with the Institute for Data, Systems, and Society.The plan is that ultimately, he says, they will develop the software to the point that “the researcher uploads their code, and with the new algorithm you automatically detect what can be improved, what can be optimized, and you return an optimized version of the algorithm to the user.”In addition to automating algorithm optimization, Zardini notes that a robust analysis of how deep-learning algorithms relate to hardware resource usage allows for systematic co-design of hardware and software. This line of work integrates with Zardini’s focus on categorical co-design, which uses the tools of category theory to simultaneously optimize various components of engineered systems.Abbott says that “this whole field of optimized deep learning models, I believe, is quite critically unaddressed, and that’s why these diagrams are so exciting. They open the doors to a systematic approach to this problem.”“I’m very impressed by the quality of this research. ... The new approach to diagramming deep-learning algorithms used by this paper could be a very significant step,” says Jeremy Howard, founder and CEO of Answers.ai, who was not associated with this work. “This paper is the first time I’ve seen such a notation used to deeply analyze the performance of a deep-learning algorithm on real-world hardware. ... The next step will be to see whether real-world performance gains can be achieved.”“This is a beautifully executed piece of theoretical research, which also aims for high accessibility to uninitiated readers — a trait rarely seen in papers of this kind,” says Petar Velickovic, a senior research scientist at Google DeepMind and a lecturer at Cambridge University, who was not associated with this work. These researchers, he says, “are clearly excellent communicators, and I cannot wait to see what they come up with next!”The new diagram-based language, having been posted online, has already attracted great attention and interest from software developers. A reviewer from Abbott’s prior paper introducing the diagrams noted that “The proposed neural circuit diagrams look great from an artistic standpoint (as far as I am able to judge this).” “It’s technical research, but it’s also flashy!” Zardini says.

Luna: A moon on Earth

MIT students and faculty designed and fabricated a control room for the first lunar landing mission since the Apollo era — an achievement in design and engineering.

On March 6, MIT launched its first lunar landing mission since the Apollo era, sending three payloads — the AstroAnt, the RESOURCE 3D camera, and the HUMANS nanowafer — to the moon’s south polar region. The mission was based out of Luna, a mission control space designed by MIT Department of Architecture students and faculty in collaboration with the MIT Space Exploration Initiative, Inploration, and Simpson Gumpertz and Heger. It is installed in the MIT Media Lab ground-floor gallery and is open to the public as part of Artfinity, MIT’s Festival for the Arts. The installation allows visitors to observe payload operators at work and interact with the software used for the mission, thanks to virtual reality.A central hub for mission operations, the control room is a structural and conceptual achievement, balancing technical challenges with a vision for an immersive experience, and the result of a multidisciplinary approach. “This will be our moon on Earth,” says Mateo Fernandez, a third-year MArch student and 2024 MAD Design Fellow, who designed and fabricated Luna in collaboration with Nebyu Haile, a PhD student in the Building Technology program in the Department of Architecture, and Simon Lesina Debiasi, a research assistant in the SMArchS Computation program and part of the Self-Assembly Lab. “The design was meant for people — for the researchers to be able to see what’s happening at all times, and for the spectators to have a 360 panoramic view of everything that’s going on,” explains Fernandez. “A key vision of the team was to create a control room that broke away from the traditional, closed-off model — one that instead invited the public to observe, ask questions, and engage with the mission,” adds Haile.For this project, students were advised by Skylar Tibbits, founder and co-director of the Self-Assembly Lab, associate professor of design research, and the Morningside Academy for Design (MAD)’s assistant director for education; J. Roc Jih, associate professor of the practice in architectural design; John Ochsendorf, MIT Class of 1942 Professor with appointments in the departments of Architecture and Civil and Environmental Engineering, and founding director of MAD; and Brandon Clifford, associate professor of architecture. The team worked closely with Cody Paige, director of the Space Exploration Initiative at the Media Lab, and her collaborators, emphasizing that they “tried to keep things very minimal, very simple, because at the end of the day,” explains Fernandez, “we wanted to create a design that allows the researchers to shine and the mission to shine.”“This project grew out of the Space Architecture class we co-taught with Cody Paige and astronaut and MIT AeroAstro [Department of Aeronautics and Astronautics] faculty member Jeff Hoffman” in the fall semester, explains Tibbits. “Mateo was part of that studio, and from there, Cody invited us to design the mission control project. We then brought Mateo onboard, Simon, Nebyu, and the rest of the project team.” According to Tibbits, “this project represents MIT’s mind-and-hand ethos. We had designers, architects, artists, computational experts, and engineers working together, reflecting the polymath vision — left brain, right brain, the creative and the technical coming together to make this possible.”Luna was funded and informed by Tibbits and Jih’s Professor Amar G. Bose Research Grant Program. “J. Jih and I had been doing research for the Bose grant around basalt and mono-material construction,” says Tibbits, adding that they “had explored foamed glass materials similar to pumice or foamed basalt, which are also similar to lunar regolith.” “FOAMGLAS is typically used for insulation, but it has diverse applications, including direct ground contact and exterior walls, with strong acoustic and thermal properties,” says Jih. “We helped Mateo understand how the material is used in architecture today, and how it could be applied in this project, aligning with our work on new material palettes and mono-material construction techniques.”Additional funding came from Inploration, a project run by creative director, author, and curator Lawrence Azerrad, as well as expeditionary artist, curator, and analog astronaut artist Richelle Ellis, and Comcast, a Media Lab member company. It was also supported by the MIT Morningside Academy for Design through Fernandez’s Design Fellowship. Additional support came from industry members such as Owens Corning (construction materials), Bose (communications), as well as MIT Media Lab member companies Dell Technologies (operations hardware) and Steelcase (operations seating). A moon on EarthWhile the lunar mission ended prematurely, the team says it achieved success in the design and construction of a control room embodying MIT’s design approach and capacity to explore new technologies while maintaining simplicity. Luna looks like variations of the moon, offering different perspectives of the moon’s round or crescent shape, depending on the viewer’s position.“What’s remarkable is how close the final output is to Mateo’s original sketches and renderings,” Tibbits notes. “That often doesn’t happen — where the final built project aligns so precisely with the initial design intent.”Luna’s entire structure is built from FOAMGLAS, a durable material composed of glass cells usually used for insulation. “FOAMGLAS is an interesting material,” says Lesina Debiasi, who supported fabrication efforts, ensuring a fast and safe process. “It’s relatively durable and light, but can easily be crumbled with a sharp edge or blade, requiring every step of the fabrication process — cutting, texturing, sealing — to be carefully controlled.”Fernandez, whose design experience was influenced by the idea that “simple moves” are most powerful, explains: “We’re giving a second life to materials that are not thought of for building construction … and I think that’s an effective idea. Here, you don’t need wood, concrete, rebar — you can build with one material only.” While the interior of the dome-shaped construction is smooth, the exterior was hand textured to evoke the basalt-like surface of the moon.The lightweight cellular glass produced by Owens Corning, which sponsored part of the material, comes as an unexpected choice for a compression structure — a type of architectural design where stability is achieved through the natural force of compression, usually implying heavy materials. The control room doesn’t use connections or additional supports, and depends upon the precise placement, size, and weight of individual blocks to create a stable form from a succession of arches.“Traditional compression structures rely on their own weight for stability, but using a material that is more than 10 times lighter than masonry meant we had to rethink everything. It was about finding the perfect balance between design vision and structural integrity,” reflects Haile, who was responsible for the structural calculations for the dome and its support.Compression relies on gravity, and wouldn’t be a viable construction method on the moon itself. “We’re building using physics, loads, structures, and equilibrium to create this thing that looks like the moon, but depends on Earth’s forces to be built. I think people don’t see that at first, but there’s something cheeky and ironic about it,” confides Fernandez, acknowledging that the project merges historical building methods with contemporary design.The location and purpose of Luna — both a work space and an installation engaging the public — implied balancing privacy and transparency to achieve functionality. “One of the most important design elements that reflected this vision was the openness of the dome,” says Haile. “We worked closely from the start to find the right balance — adjusting the angle and size of the opening to make the space feel welcoming, while still offering some privacy to those working inside.”The power of collaborationWith the FOAMGLAS material, the team had to invent a fabrication process that would achieve the initial vision while maintaining structural integrity. Sourcing a material with radically different properties compared to conventional construction implied collaborating closely on the engineering front, the lightweight nature of the cellular glass requiring creative problem-solving: “What appears perfect in digital models doesn’t always translate seamlessly into the real world,” says Haile. “The slope, curves, and overall geometry directly determine whether the dome will stand, requiring Mateo and me to work in sync from the very beginning through the end of construction.” While the engineering was primarily led by Haile and Ochsendorf, the structural design was officially reviewed and approved by Paul Kassabian at Simpson Gumpertz and Heger (SGH), ensuring compliance with engineering standards and building codes.“None of us had worked with FOAMGLAS before, and we needed to figure out how best to cut, texture, and seal it,” says Lesina Debiasi. “Since each row consists of a distinct block shape and specific angles, ensuring accuracy and repeatability across all the blocks became a major challenge. Since we had to cut each individual block four times before we were able to groove and texture the surface, creating a safe production process and mitigating the distribution of dust was critical,” he explains. “Working inside a tent, wearing personal protective equipment like masks, visors, suits, and gloves made it possible to work for an extended period with this material.”In addition, manufacturing introduced small margins of error threatening the structural integrity of the dome, prompting hands-on experimentation. “The control room is built from 12 arches,” explains Fernandez. “When one of the arches closes, it becomes stable, and you can move on to the next one … Going from side to side, you meet at the middle and close the arch using a special block — a keystone, which was cut to measure,” he says. “In conversations with our advisors, we decided to account for irregularities in the final keystone of each row. Once this custom keystone sat in place, the forces would stabilize the arch and make it secure,” adds Lesina Debiasi.“This project exemplified the best practices of engineers and architects working closely together from design inception to completion — something that was historically common but is less typical today,” says Haile. “This collaboration was not just necessary — it ultimately improved the final result.”Fernandez, who is supported this year by the MAD Design Fellowship, expressed how “the fellowship gave [him] the freedom to explore [his] passions and also keep [his] agency.”“In a way, this project embodies what design education at MIT should be,” Tibbits reflects. “We’re building at full scale, with real-world constraints, experimenting at the limits of what we know — design, computation, engineering, and science. It’s hands-on, highly experimental, and deeply collaborative, which is exactly what we dream of for MAD, and MIT’s design education more broadly.”“Luna, our physical lunar mission control, highlights the incredible collaboration across the Media Lab, Architecture, and the School of Engineering to bring our lunar mission to the world. We are democratizing access to space for all,” says Dava Newman, Media Lab director and Apollo Professor of Astronautics.A full list of contributors and supporters can be found at the Morningside Academy of Design's website.

Biden let California get creative with Medicaid spending. Trump is signaling that may end

California uses Medicaid to pay for a range of nontraditional health care services, including housing. The Trump administration wants to scale back those programs.

In summary California uses Medicaid to pay for a range of nontraditional health care services, including housing. The Trump administration wants to scale back those programs. In 2022, California made sweeping changes to its Medi-Cal program that reimagined what health care could look like for some of the state’s poorest and sickest residents by covering services from housing to healthy food. But the future of that program, known as CalAIM, could be at risk under the Trump administration.  In recent weeks, federal officials have signaled that support for creative uses of Medi-Cal funding is waning, particularly uses that California has invested in such as rent assistance and medically tailored meals. Medi-Cal is California’s name for Medicaid. The moves align with a narrower vision of Medicaid espoused by newly confirmed Centers for Medicare and Medicaid Services head Dr. Mehmet Oz, who said during his swearing-in ceremony that Medicaid spending was crowding out spending on education and other services in states with the federal government “paying most of the bill.” “This one really bothers me. There are states who are using Medicaid — Medicaid dollars for people who are vulnerable — for services that are not medical,” Oz said. It also fits with broader GOP calls to slim down the federal government. Medicaid is under scrutiny as part of a GOP-led budget process in the House of Representatives that calls for $880 billion in cuts over 10 years to programs including Medicaid. “The messaging that we want to go back to the basics of Medicaid puts all of these waiver programs in jeopardy,” said John Baackes, former chief executive of L.A. Care, the state’s largest Medi-Cal health insurer. CalAIM is authorized under a federal waiver that allows states to experiment with their Medicaid programs to try to save money and improve health outcomes. Under the waiver, California added extra benefits for high-cost users to help with food insecurity, housing instability,  substance use and behavioral health challenges. Roughly half of all Medi-Cal spending can be attributed to 5% of high-cost users, according to state documents. But in March, the federal government rescinded guidelines supporting Medi-Cal spending for social services. It also sent states a letter in April indicating that the Centers for Medicare and Medicaid Services would no longer approve a funding mechanism that helps support CalAIM, although that money will continue until 2026. Together, these moves should worry states that operate programs like CalAIM, said Kathy Hempstead, senior policy officer at the Robert Wood Johnson Foundation. “Under the Biden administration states were encouraged to experiment with things like that: To prescribe people prescriptions to get healthy food, to refer people to community-based services,” Hempstead said. “This administration is not receptive at all to … that vision of the Medicaid program.” In a press release, CMS said it is putting an end to spending that isn’t “directly tied to health care services.” “Mounting expenditures, such as covering housekeeping for individuals who are not eligible for Medicaid or high-speed internet for rural healthcare providers, distracts from the core mission of Medicaid, and in some instances, serves as an overly-creative financing mechanism to skirt state budget responsibilities,” the press release states. These signals from the federal government apply to future applications for Medicaid changes, and do not change California’s current programs or funding. The state’s CalAIM waiver expires at the end of 2026, and another similar waiver that supports California’s efforts to improve behavioral health care expires in 2029. According to a statement from the Department of Health Care Services, the agency that oversees Medi-Cal, all programs “remain federally approved and operational.” “We appreciate our Medi-Cal providers and community partners, and together we will push full steam ahead to transform our health system and improve health outcomes,” the department said.

Photo by Larry Valenzuela, CalMatters/CatchLight Local Paul Shafer, co-director of the Boston University Medicaid Policy Lab, said decades of public health research show that people have worse health outcomes that require more expensive treatment when their social needs aren’t met. “We’ve spent the last few decades in public health and health policy, arguing that so much of health and medical costs is driven by environmental factors — people’s living conditions, income, etc.” Shafer said. But, Shafer said, programs like CalAIM are relatively recent and the research hasn’t had enough time to show whether paying for non-traditional services saves money. For example, California’s street medicine doctors who take care of people who are homeless say that their patients often cycle in and out of the emergency room — the most expensive point of service in the health care system. They have no place to recover from medical procedures, no address to deliver medications, and the constant exposure to the elements takes years off of their lives, doctors say.  CalAIM gives them options to help their clients find housing.  The federal government’s decision not to fund programs like this in the future is a “step backward,” Shafer said.  “I think we can all read the tea leaves and say that that means they’re sort of unlikely to be renewed,” he said.
