Researchers have noticed a growing problem as artificial intelligence systems begin to score very high on academic benchmarks that have been used for years. The tests once imposed on machines were no longer difficult enough. Well-known assessments such as the Massive Multi-Task Language Understanding (MMLU) exam, which was previously considered too demanding, are no longer able to adequately measure the capabilities of today’s advanced AI models. To solve this problem, a global group of nearly 1,000 researchers, including professors at Texas A&M University, developed a new type of test. Their goal was to build a broad, difficult, and human-expertise test…

Recent research published in autism research suggest that the cognitive changes associated with autism are significantly greater in women than in men. The findings provide evidence that women may require greater biological stimulation to develop autism, which helps explain why autism is diagnosed more often in boys. These insights reveal psychological differences underlying the male-biased prevalence of autism spectrum disorders. The extreme male brain theory of autism was originally proposed by Cambridge University psychologist Simon Baron Cohen. This theory suggests that autism exaggerates typical male cognitive characteristics. Specifically, it refers to a profile that exhibits relatively low empathy, known as…

New research from Arizona State University shows that bacteria can move in unexpected ways even when normal propulsion systems fail. Bacteria normally move using flagella, long, thin whip-like structures that rotate to push the cell forward. New research has revealed that microorganisms can spread across surfaces even without these structures. Movement is very important for bacteria. It allows them to gather in communities, explore new environments, and escape harmful situations. Knowing how bacteria move may help scientists develop better strategies to prevent infection. In the first study, researcher Navish Wadhwa and his team found that salmonella and Escherichia coli Even…

Many tobacco researchers and policy experts believe that e-cigarettes have potential as a tool to help people quit smoking. But they also want to prevent teens from picking up the habit and becoming addicted to nicotine.The tension between these two goals is at the heart of new draft guidance on flavored e-cigarettes from the Food and Drug Administration this week to e-cigarette manufacturers. The document suggests that e-cigarettes in flavors such as coffee, mint and cinnamon could be approved for sale. Some public health experts, along with anti-tobacco advocates, worry that the change could set the U.S. back in its…

WASHINGTON — White House officials are steering the Trump administration away from vaccine reform, fearing the political fallout of emphasizing a relatively unpopular issue during a critical election year. But the “Make America Healthy” movement, led by Secretary of Health Robert F. Kennedy Jr., who has a history of anti-vaccination activism, is not going without a fight. The change in government began late last year, especially as the midterm elections approached, when Republican pollster Tony Fabrizio released a memo saying that “vaccine skepticism is bad politics.” STAT+ exclusive story Already have an account?

Gold cannot form until certain unstable atomic nuclei decompose. It has long been difficult to understand exactly how these nuclear changes unfold. Now, nuclear physicists at the University of Tennessee (UT) have reported three discoveries in a single study that reveal key parts of this process. Their findings could help researchers build improved models of stellar phenomena that produce heavy elements and more accurately predict the behavior of exotic nuclei. Heavy elements such as gold and platinum are forged under unusual conditions such as star collapse, explosions, and collisions. These events trigger a rapid neutron capture process (r-process for short).…

Researchers at Trinity College in Dublin report the discovery of what they believe to be a “universal thermal performance curve” (UTPC) that applies to the entire tree of life. The researchers say this pattern determines how organisms respond to changes in temperature. The results of this study suggest that this rule is effectively an “evolutionary shackle.” This is because the species studied so far have not been able to escape the limitations this regulation imposes on the effects of temperature on biological performance. Temperature affects all living things. The newly described UTPC brings together tens of thousands of previously individual…

Scientists have found the strongest evidence yet that a black hole and a neutron star collided while traveling along elliptical orbits, rather than the near-perfect circle that scientists typically expect before such a merger. The discovery challenges long-held ideas about how these extreme cosmic pairs form and evolve. The research was carried out by scientists from the University of Birmingham, the Autonomous University of Madrid and the Max Planck Institute for Gravitational Physics. Their findings were published on March 11th. Astrophysics Journal Letter. Unusual elliptical orbit discovered after black hole and neutron star merge Astronomers generally expect neutron star-black hole…

aAs soon as the barrier broke, a poisonous flood brought death to the river. In February 2025, more than 50 meters cubic liters of acid and heavy metals leaked through a weak wall built to contain mining waste in Zambia’s copper belt and into the Chambisi River, a tributary of the Kafue River, the country’s longest waterway.A plume of acid drifted downstream, bringing thousands of lifeless fish to the surface and leaving behind the carcasses of crocodiles and other wildlife.For the millions of Zambians who depend on Kafue, the collapse of the tailing dam at the Chinese state-owned Sino Metals…

Iconeus, a French neuroimaging company developing functional ultrasound (fUS) solutions for real-time brain activity imaging, today announced the formation of a U.S. corporation, Iconeus Inc. This is an important milestone in supporting the introduction of functional ultrasound in preclinical neuroscience research. The new U.S. location will enable closer collaboration with U.S. academic institutes, research institutions, pharmaceutical companies, and contract research organizations that use advanced imaging to study brain function, neurological diseases, and the development of treatments. As part of this expansion, Iconeus has appointed Joshua Dufresne, the company’s first U.S.-based team member, as Business Development Manager. He will drive strategic…
