The Federal Trade Commission and four state attorneys general have sued a leading professional organization of gender-affirming care clinicians for making false claims about selling medical services to children. The lawsuit against the World Association of Transgender Health Professionals, filed Wednesday in federal court in Texas, is part of the Trump administration’s broader effort to end gender-affirming care for minors. The FTC and the attorneys general of Alaska, Iowa, Nebraska, and Texas allege in the lawsuit that WPATH misled children and parents about the benefits and risks of surgeries and drugs and “led many consumers to believe that its treatment…

Increased levels of highly abundant chemical messengers in the brain are associated with increased sensitivity to mistakes. This exaggerated response to mistakes helps explain why some people are more likely to experience overlapping symptoms of anxiety and depression. The study was published in the journal Frontiers of neuroscience. The anterior insular cortex is a structure located deep in the brain. Gather information about physical sensations, emotional states, and unexpected consequences. People dealing with anxiety often show abnormally high activity in this area when monitoring themselves for mistakes or recognizing potential threats. Glutamate is the main excitatory chemical in the human…

Vorpoise (Fokoena Bay) is a small porpoise found only in the shallow waters of the northern Gulf of California, Mexico, and is one of the most endangered marine mammals on Earth. At about 5 feet long, it is the smallest member of the cetacean group, which includes whales, dolphins, and porpoises. The vaquita, identified by the black spots around its eyes and mouth, was unknown to science until the late 20th century. Today, it has become a powerful symbol of the biodiversity crisis affecting oceans around the world. There are only an estimated small number of vaquita porpoises left in…

Bacteria that produce intestinal toxins Escherichia coli and Staphylococcus ruber Together, they cause hundreds of millions of infections each year and are one of the leading causes of diarrheal deaths, especially in children. Decades of vaccine development efforts have been inadequate, in part because the targets of conventional vaccines vary widely from strain to strain. A new study from Washington University School of Medicine in St. Louis points out that these enteric pathogens have common biological characteristics that could lead to a vaccine that protects against both. Researchers at WashU Medicine, along with collaborators at the University of Missouri and…

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…
