Only three people prosecuted for covering up illegal sewage spills

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.

The greater Pittsburgh region is among the 25 worst metro areas in the country for air quality: Report

PITTSBURGH — The greater Pittsburgh metropolitan area is among the 25 regions in the country with the worst air pollution, according to a new report from the American Lung Association.The nonprofit public health organization’s annual “State of the Air” report uses a report card-style grading system to compare air quality in regions across the U.S. This year’s report found that 46% of Americans — 156.1 million people — are living in places that get failing grades for unhealthy levels of ozone or particulate pollution. Overall, air pollution measured by the report was worse than in previous years, with more Americans living in places with unhealthy air than in the previous 10 years the report has been published.The 13-county region spanning Pittsburgh and southwestern Pennsylvania; Weirton, West Virginia; and Steubenville, Ohio received “fail” grades for both daily and annual average particulate matter exposure for the years 2021–2023.The region ranked 16th worst for 24-hour particle pollution out of 225 metropolitan areas and 12th worst for annual particle pollution out of 208 metropolitan areas. Particulate matter pollution, which comes from things like industrial emissions, vehicle exhaust, wildfires, and wood burning, causes higher rates of asthma, decreased lung function in children, and increased hospital admissions and premature death due to heart attacks and respiratory illness. Long-term exposure to particulate matter pollution also raises the risk of lung cancer, and research suggests that in the Pittsburgh region, air pollution linked to particulate matter and other harmful substances contributes significantly to cancer rates. According to the report, the Pittsburgh metro area is home to around 50,022 children with pediatric asthma, 227,806 adults with asthma, 173,588 people with Chronic Obstructive Pulmonary Disease (COPD), 250,600 people with cardiovascular disease, 1,468 people with lung cancer, and around 25,746 pregnant people, all of whom are especially vulnerable to the harmful impacts of particulate matter pollution exposure."The findings help community members understand the ongoing risks to the health of people in our region," said Matt Mehalik, executive director of the Breathe Project and the Breathe Collaborative, a coalition of more than 30 groups in southwestern Pennsylvania that advocate for cleaner air. "These findings emphasize the need to transition away from fossil fuels — in industry, transportation and residential uses — if we are to improve our health and address climate change." Allegheny County has received a failing grade for particulate matter pollution from the American Lung Association every year since the "State of the Air" report was first issued in 2004. The region is home to numerous polluting industries, with an estimated 80% of toxic air pollutants in Allegheny County (which encompasses Pittsburgh) coming from ten industrial sites, according to an analysis by the nonprofit environmental advocacy group PennEnvironment Research & Policy Center. The Ohio River near Pittsburgh Credit: Kristina Marusic for EHN In the 2024 State of the Air report, which looked at 2020-2022, Pittsburgh was for the first time ever not among the 25 cities most polluted by particulate matte, and showed some improvements in air quality, some of which may have resulted from pollution reductions spurred by the COVID-19 shut-down in 2020.The region earned a grade D for ozone smog this year, but its ranking improved from last year — it went from the 50th worst metro area for ozone smog in 2024’s report to the 90th worst in this year’s. Ozone pollution also comes from sources like vehicle exhaust and industrial emissions, and occurs when certain chemicals mix with sunlight. Exposure to ozone pollution is linked to respiratory issues, worsened asthma symptoms, and long-term lung damage.Each year the State of the Air Report makes recommendations for improving air quality. This year those recommendations include defending funding for the U.S. Environmental Protection Agency (EPA), because sweeping staff cuts and reduction of federal funding under the Trump administration are impairing the agency’s ability to enforce clean air regulations. For example, the report notes that EPA recently lowered annual limits for fine particulate matter pollution from 12 micrograms per cubic meter to 9 micrograms per cubic meter, and that states, including Pennsylvania, have submitted their recommendations for which areas should be cleaned up. Next, the agency must review those recommendations and add its own analyses to make final decisions by February 6, 2026 about which areas need additional pollution controls. If it fails to do so due to lack of funding or staffing, the report suggests, air quality might suffer.“The bottom line is this,” the report states. “EPA staff, working in communities across the country, are doing crucial work to keep your air clean. Staff cuts are already impacting people’s health across the country. Further cuts mean more dirty air.”

Oregon Indigenous farm navigating uncertainty over federal grants

One federal grant awarded to the farm was recently restored but two others are still on hold.

A few miles south of Salem, the Elderberry Wisdom Farm uses generations of traditional knowledge to grow native plants, restore habitats and train Indigenous adults and other underrepresented students for careers in agriculture. The six-year-old farm has received much of its funding through state and federal grants — but a farm founded on principles of equity and sustainability is a target for cuts under the Trump administration. As she led U.S. Rep. Andrea Salinas, D-Oregon, on a tour of the farm Wednesday, founder Rose High Bear half-jokingly asked if she could still use the words “equity” and “climate,” both terms Trump and his team have disparaged and used as keywords to find disfavored programs and policies. One $750,000 grant, awarded to the farm and community partners to expand tree canopies, was temporarily frozen but restored as of last week, following a letter from Salinas. Two other federal grants meant for workforce development are still on hold. “We need to restore the planet, and this is one way to do it,” Salinas said. “I keep saying, let’s bring all solutions to the table. This is just one, but if I can write a letter and unfreeze funds, I’m going to do it.” High Bear, an Alaska Native of Deg Hitʼan and Inupiat descent, founded the farm in 2019 after retiring as executive director of Wisdom of the Elders, a Portland-based nonprofit dedicated to preserving and sharing Indigenous history. She said the work is spiritual, and that she trusts ancestors will help guide the farm’s workers to accomplish their task of restoring the earth and raising awareness of traditional ecological knowledge. “We have no doubt in our mind that what we’re doing is right,” High Bear said. “If a government doesn’t necessarily believe in it, that doesn’t mean they’re going to stop us from doing our work — no matter what, we’re going to accomplish it.”Right now, much of the work consists of developing a native tree nursery, with Willamette Valley ponderosa pines, as well as firs and other pines native to the region. About 1,000 of those trees, as well as companion shrubs and pollinator ground cover plants, will be planted in areas of Salem that lack tree canopies. The farm will work with local high school students, as well as its adult interns, on the project. Natural shade from tree canopies helps cool the air and reduce air pollution. Nearby trees also increase home values and help prevent stormwater runoff. The farm will also feature a garden planted with the “three sisters” — maize, beans and squash — growing together. Hopi corn will provide a natural trellis for the Cherokee Trail of Tears beans, which convert nitrogen in the air to soil nitrates. Leaves of the summer and winter squash that make up the lower level provide shade, suppress weeds and retain soil moisture. The farm doesn’t use pesticides. Instead, workers manually remove most pests — and are resigned to some others, including deer who wander through nibbling on plants. “This is our oldest grandmother here, Mother Earth, and we’re not going to put poison on her just to get rid of our new neighbors,” High Bear said. Dawn Lowe, an Indigenous traditional ecological knowledge instructor of Hawaiian, Apache, Cherokee, and Mohawk descent, told Salinas the farm could always use more grant money to expand its work. “There’s a lot that we want to be able to achieve in the crisis we’re living through,” Lowe said. Each day at the farm includes some classtime, with videos or reading, and a discussion about a different topic. On Wednesday, that topic was seeds — saving, germinating and choosing them. Then interns spend time working with plants, including transplanting native pines and planting an elderberry forest heading up the hill.For Joaquin Ocaña, interning at the Elderberry Wisdom Farm is part of connecting with his heritage. On his father’s side, Ocaña is descended from the Kaqchikel people, an Indigenous Maya group from the highlands of Guatemala. Trying to connect to that side of his identity over the past few years led Ocaña to farming and spirituality, but feeling that connection is still a work in progress, Ocaña said. “I’ve never actually been to the place where my people are from, so I think that part is kind of lacking for now,” he said. “I’m still very young and figuring it out, but there are some things that as an individual that you can pay attention to and feel. Those can be my family guiding me and helping me along the way.”Intern Amanda Puitiza, an Oregon State University graduate student completing her Ph.D. in animal sciences, said she learned more about ecology and traditional practices at the farm than she did through her classes or prior work. She grew up in New York, and on the East Coast she said there wasn’t as much discussion about traditional practices outside of specific communities. “I’m really happy to get another perspective on how we’re protecting the environment or the ecosystem, trying to make it healthier,” Puitiza said. “I think it makes me a better learner and teacher in general, just to have more perspectives.” C.J. Senn, an enrolled member of the Umatilla Tribe, pivoted from 13 years working as a pastry chef to finishing her double major in environmental studies and science at Portland State University. After graduation, she’ll join her tribe working on huckleberry genealogy. The most valuable thing Senn has learned through interning at the Elderberry Wisdom Farm, and that she hopes to continue working on, is how to relate to plants and animals. “It’s really just about being a part of it, rather than trying to manipulate it,” Senn said. -- Julia Shumway, Oregon Capital ChronicleThe Oregon Capital Chronicle, founded in 2021, is a nonprofit news organization that focuses on Oregon state government, politics and policy.

New, 'Living' Building Material Made From Fungi and Bacteria Could Pave the Way to Self-Healing Structures

Researchers are developing the biomaterial as a more environmentally friendly alternative to concrete, but any wide-scale use is still far away

New, ‘Living’ Building Material Made From Fungi and Bacteria Could Pave the Way to Self-Healing Structures Researchers are developing the biomaterial as a more environmentally friendly alternative to concrete, but any wide-scale use is still far away Microscopic images of the bacteria and mycelium scaffolds. The circles indicate the likely presence of S. pasteurii bacteria. Viles, Ethan et al., Cell Reports Physical Science 2025 Concrete is a crucial construction material. Unfortunately, however, producing it requires large amounts of energy—often powered by fossil fuels—and includes chemical reactions that release carbon dioxide. This intensive process is responsible for up to 8 percent of humanity’s carbon dioxide emissions. As such, finding more sustainable building materials is vital to lessening our global carbon footprint. And to help achieve this goal, scientists are studying methods that might replace concrete with biologically derived materials, or biomaterials for short. Now, researchers have developed a building material made of mycelium—the tubular, branching filaments found in most fungi—and bacteria cells. As detailed in a study published last week in the journal Cell Reports Physical Science, the living bacteria survived in the structure for an extended amount of time, laying the groundwork for more environmentally friendly and self-healing construction material down the line. The researchers grew mycelium from the fungus Neurospora crassa, commonly known as red bread mold, into a dense, scaffold-like structure. Then, they added Sporosarcina pasteurii bacteria. “We like these organisms for several reasons,” Chelsea Heveran, a co-author of the study and an expert in engineered living materials at Montana State University, tells the Debrief’s Ryan Whalen. “First, they do not pose very much threat to human health. S. pasteurii is a common soil microorganism and has been used for years in biomineralization research, including in field-scale commercial applications. N. crassa is a model organism in fungal research.” They also liked that both organisms are capable of biomineralization—the process that forms bones and coral by creating hardened calcium carbonate. To set off biomineralization, the team placed the scaffold in a growing medium with urea and calcium. The bacteria formed calcium carbonate quickly and effectively, making the material stronger. Importantly, the bacteria S. pasteurii was alive, or viable, for at least a month. Live organisms in building material could offer unique properties—such as the ability to self-repair or self-clean—but only as long as they’re alive. This study didn’t test those traits specifically, according to a statement, but the longer lifetime of this material “lays the groundwork for these functionalities.” “We are excited about our results,” Heveran tells New Scientist’s James Woodford. “When viability is sufficiently high, we could start really imparting lasting biological characteristics to the material that we care about, such as self-healing, sensing or environmental remediation.” This month-long lifespan marks a significant improvement over previous structures. In fact, a major challenge in the development of living biomaterials is their short viability—other similar materials made with living organisms have remained viable for just days or weeks. Plus, they don’t usually form the complex internal structures necessary in construction projects, according to the statement. In the new study, however, “we learned that fungal scaffolds are quite useful for controlling the internal architecture of the material,” Heveran explains in the statement. “We created internal geometries that looked like cortical bone, but moving forward, we could potentially construct other geometries, too.” Ultimately, the researchers developed a tough structure that could provide the basis for future sustainable building alternatives. As reported by New Atlas’ Abhimanyu Ghoshal, however, scientists still have other challenges to tackle on the path to replacing concrete—for instance, scaling the material’s production, making it usable for different types of construction projects and overcoming the higher costs associated with living biomaterials. These materials, so far, “do not have high enough strength to replace concrete in all applications,” Heveran says in the statement. “But we and others are working to improve their properties so they can see greater usage.” To that end, Aysu Kuru, a building engineer at the University of Sydney in Australia who did not participate in the study, tells New Scientist that “proposing mycelium as a scaffolding medium for living materials is a simple but powerful strategy.” Get the latest stories in your inbox every weekday.
