Scientists report that a persistent cold patch in the North Atlantic, known as the 'cold blob,' points to a weakening of the Atlantic Meridional Overturning Circulation (AMOC), a key climate-regulating current. If AMOC collapses, it could dramatically alter weather patterns across Europe and North America. The finding comes from new ocean temperature modeling.
After more than 50 years of searching, astrophysicists at Northwestern University have detected a powerful wind blowing from Sagittarius A*, the supermassive black hole at the center of the Milky Way. Using five years of ALMA telescope observations, they found a cone-shaped cavity carved by the wind. The discovery confirms that our galaxy's black hole behaves like all others, resolving one of astronomy's longest-standing mysteries.
An artificial intelligence system has cracked a decades-old mathematics problem originally posed by the legendary Paul Erdős, marking a new milestone for machine reasoning and automated theorem proving. The breakthrough, reported by ScienceNews, demonstrates that AI systems can now tackle problems that have stumped human mathematicians for years. Separately, astronomers may have found a record-breaking pair of black holes, and a new species of ancient bear-dog was identified in Spain, highlighting a week of diverse scientific discoveries.
A new study published in Science reveals that metal-driven chemical reactions in deep-sea hydrothermal vents could have produced the organic molecules necessary for life to emerge on Earth. The finding provides experimental evidence that iron and nickel from vent minerals can catalyze the formation of amino acids and nucleotides under early Earth conditions, with implications for the search for life on Saturn's moon Enceladus and Jupiter's moon Europa.
An artificial intelligence system has successfully solved a long-standing mathematics problem associated with the legendary Paul Erdős, researchers reported. The achievement demonstrates AI's growing capability in automated mathematical reasoning, a field that has traditionally resisted machine assistance. Separately, scientists announced laser-boosted microscopes that could reveal new drugs, and researchers uncovered why hantavirus is so deadly. The breakthroughs highlight how AI and advanced optics are accelerating discovery across scientific disciplines.
An AI model solved an 80-year-old geometry conjecture posed by Hungarian mathematician Paul Erdős, marking what researchers call AI's biggest math breakthrough yet. The problem, which stumped human mathematicians for decades, was solved via a straightforward query to an AI chatbot. The solution found a more complex way to arrange pairs of points than mathematicians had ever conceived. The breakthrough has reignited debates about AI's role in mathematical discovery and led to calls for 'guardrails' on AI use in research, with the Leiden Declaration urging caution.
NASA named the four-person crew for the Artemis III mission on Tuesday, led by commander Randy Bresnik, European Space Agency astronaut Luca Parmitano as pilot, and mission specialists Frank Rubio and Andre Douglas. While Artemis III will not land on the Moon, it will test critical systems needed for the planned Artemis V Moon landing in 2028. The announcement comes as NASA's Landsat satellite data reveals mangrove forests are expanding globally for the first time in decades.
The James Webb Space Telescope has directly detected methane on interstellar comet 3I/ATLAS, the first time this molecule has been found on an object from outside our solar system. The methane-to-water ratio is surprisingly high, suggesting the comet formed around a different type of star in a distant planetary system.
NASA has declared its MAVEN Mars orbiter dead after losing contact with the spacecraft in December 2025. The $582 million probe spent 11 years studying Mars' atmosphere and how solar wind stripped the planet of its water. Only two NASA orbiters remain operational around Mars.
Researchers at the Institute for Neurosciences in Spain identified a specific population of neurons in the basolateral amygdala that triggers anxiety and social withdrawal when imbalanced. By restoring normal activity in this tiny brain circuit, they reversed anxiety-related behaviors in both genetically engineered and naturally anxious mice. The finding opens the door to more targeted treatments for anxiety disorders.
