Scientists have identified a specific brain circuit that appears to play a major role in anxiety, depression-like behaviors, and social withdrawal. Even more striking, they found that restoring balance within this circuit was enough to reverse several of these behaviors in mice. The research was led by Juan Lerma and his team at the Synaptic…
A new study shows that computer malware powered by easily accessible artificial intelligence models is here—the research is a “wake-up call” to take cybersecurity risks from AI more seriously, one expert says. In the study, researchers created an AI-powered computer “worm” designed to attack and spread between devices—revealing a threat that they say the world…
ChatGPT now processes around 2.5 billion queries every day Alina Vytiuk / Alamy Stock Photo UN researchers are urging people to be less polite to artificial intelligences after a report found that cutting words from prompts could reduce ChatGPT’s energy consumption by up to 25 per cent. Removing “please”, “thank you” and other unnecessary words…
Sea level height data from the international Sentinel-6 Michael Freilich satellite collected from March to May 2026 show higher, warmer water moving from the western Pacific Ocean to just off the coast of Colombia, Ecuador, and Peru. This phenomenon is known as a warm Kelvin wave, signified in this animation of the data by yellow,…
A newly developed pill could offer a fresh approach to treating type 2 diabetes and obesity. Early research suggests it may help lower blood sugar and increase fat burning without reducing appetite or causing muscle loss, two common concerns associated with some current weight loss medications. The findings, published in the journal Cell, come from…
The 27° east meridian, running through Europe and Africa, divides Earth into two equally reflective halves PLANETARY VISIONS LTD/SCIENCE PHOTO LIBRARY A line that runs through Africa, Europe, Alaska and both poles divides Earth into two halves that reflect the same amount of light – and this newly discovered symmetry may play a critical role…
NASA-supported scientists have provided new information about how the early Earth may have acquired some elements necessary for the planet to become habitable. They also suggest a new role for Jupiter in the distribution of these elements throughout the young solar system. The study, published today in Science Advances, examines this history by looking at…
When a nuclear weapon detonates or a serious reactor accident occurs, an immense burst of energy is released in less than a millionth of a second. The extreme heat instantly vaporizes nearby air and materials, creating a brilliant, expanding cloud of gas and plasma. As this nuclear fireball grows, it mixes with the surrounding atmosphere,…
Mark Thomson has taken the reins at CERN just as particle physics confronts some of its deepest unknowns – and faces hard choices about what comes next
The first mission devoted to observing the Martian atmosphere and its evolution, NASA’s MAVEN (Mars Atmosphere and Volatile Evolution), has ended after more than 11 years in orbit at Mars and a decade beyond its primary, one-year mission. The spacecraft was heard last on Dec. 6, when it experienced an unexpected loss of signal after…
