The Trump administration has argued that the federal government can cancel Clean Air Act lawsuits brought by citizens against polluters, but environmental lawyers warn that this would rewrite decades of enforcement law. If successful, the argument made by the Justice Department in a court filing supporting Elon Musk’s artificial intelligence companies would dramatically undermine the ability of Americans to fight pollution at tens of thousands of industrial sites across the country. “This would be a fairly fundamental change in how federal pollution control laws are enforced,” said Tom Mariani, former director of environmental enforcement at the Justice Department. The Clean…

Researchers at the Niigata University Brain Research Institute have discovered a new function for amyloid precursor protein (APP), a molecule long studied as a precursor to amyloid-β (Aβ) in Alzheimer’s disease (AD). This study demonstrates that APP actively protects neurons by expelling damaged nuclear material through a process called lysosomal exocytosis, providing a fundamentally new way of thinking about AD. APP is best known as the protein whose enzymatic cleavage generates the Aβ peptide. Accumulation of Aβ in the brain is a hallmark of AD. However, the physiological function of full-length APP before cleavage is still not well understood. It…

The first, robot-assisted osteotomy, uses an optical tracking system and a collaborative robotic arm to guide the bone saw. The hand-eye calibration procedure determines the exact pose of the robot’s end effector relative to the tracking marker. During the procedure, the surgeon tracks the surface of the bone with an optical probe. The acquired point cloud is registered to the preoperative CT model using the Super4PCS algorithm. The robotic arm then moves the slotted jig to the planned osteotomy plane. The slot physically restrains the saw blade to ensure accurate angle and depth, while the tracking marker compensates for slight…

North Carolina’s long-standing ban on hardened structures such as piers and seawalls to control coastal erosion appears to be in effect by the end of the legislative session in 2026. On Wednesday, members of the Senate Agriculture, Energy and Environment Committee introduced a bill that would eliminate the ban on such structures and require the North Carolina Collaborative Research Institute at UNC-Chapel Hill to update the state’s beach and cove management plan. Sen. Bob Brinson (R-Beaufort), the lead sponsor of Senate Bill 1009, said policies created 40 years ago to protect North Carolina’s coastline should not be subject to review.…

summary In early May, 49 birds were discovered in a tailings pond at Imperial Oil’s Carle oil sands mine. Later that month, 95 birds were found dead at the Suncor Fire Bag site. In 2025, the Alberta government’s Oil Sands Mine Water Steering Committee recommended accelerating the development of standards for the treatment and release of tailings produced as a byproduct of the oil extraction process. Processing and discharging tailings into the river has been criticized by downstream First Nations, including the Mixaw Cree First Nation. At Jean L’Hommecourt’s cabin north of Fort McMurray, bird calls are frequently interrupted by…

Hundreds of genes are thought to be associated with autism, but the precise molecular and cellular mechanisms behind them remain largely unknown. New research published in natureA research team led by Gaia Novallino from the Austrian Institute of Science and Technology (ISTA) aims to uncover these mechanisms, which could lay the foundations for the development of medical therapies. Autism spectrum conditions, often abbreviated as ASD in the scientific and medical literature, are neurodevelopmental disorders such as epilepsy and intellectual disability, for example. Fundamental changes begin early in brain development, but the first signs are often evident in early childhood…

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are widely prescribed to treat diabetes and obesity, but research has found evidence that they may also have behavioral effects, including supporting impulse control and reducing substance use and alcohol intake, by potentially interacting with the brain’s reward and stress systems. new research in criminology It adds to this growing body of evidence. Researchers analyzed data from a 2025 nationally representative US survey of 821 adults who had ever used GLP-1 drugs and found that while impulsivity and alcohol use were strongly associated with violent crime, these associations were significantly weaker among current GLP-1…

Popular GLP-1 treatments such as Ozempic and Wegovy are best known for helping with weight loss and diabetes management. A new study from Rutgers University suggests that these drugs may also be associated with behavioral changes related to violence. This study criminologyinvestigated whether GLP-1 receptor agonists influence violent criminal behavior in adults. The researchers focused on whether drugs could alter the effects of two factors strongly associated with violence: impulsivity and alcohol consumption. GLP-1 Drugs and Violence To explore this question, researchers analyzed data from a 2025 survey of 7,521 adults across the United States. Their main analysis focused on…

To reach the regions of the cerebral cortex that form neural circuits, newborn nerve cells must pass through dense, narrow spaces, through dense tissue, past other cells, and between fibers. In a new study published in natureresearchers at Kyoto University’s Institute for Cellular and Materials Science (WPI-iCeMS) and their collaborators report that this journey causes extensive DNA damage in neurons, causing double-strand breaks in which both strands of the double helix are completely severed. Although this is the most severe type of DNA damage that can cause mutations and cell death, the researchers surprisingly discovered that this is a normal,…

Fitness wearables company Whoop on Wednesday announced a partnership with health platform HealthEx. This will allow users to connect their medical records directly within the Whoop app, combining medical history and biometric data. The companies say the partnership “meets the growing need” for a “more connected health experience” for users. The new integration allows for various factors such as chronic disease, recent procedures, etc. to be considered alongside tracking metrics such as performance and sleep. “Whoop has always been focused on turning data into meaningful insights,” said Alex Vannoni, Whoop head of healthcare products, in a statement. “This partnership extends…
