NASA appears to be backing away from the search for life on Mars, raising concerns among planetary scientists that the agency is deprioritizing one of space exploration's most profound questions. In a separate development, an AI system cracked a long-unsolved problem by mathematician Paul Erdős, prompting calls for guardrails on AI mathematical research. New NIH security rules for genomic data sets are slowing research, and astronomers may have found the largest pair of black holes ever recorded, on a collision course.
Researchers have used artificial intelligence to uncover new antibiotic candidates inside prion proteins—misfolded brain proteins best known for causing rare neurodegenerative diseases. Published June 19 in Nature Microbiology, the study from the University of Pennsylvania found that AI analysis of prion protein structures revealed antimicrobial properties never before detected. The discovery opens an unexpected frontier in the search for new antibiotics at a time when drug-resistant bacteria pose a growing global health threat and the pipeline for new treatments remains thin.
An artificial intelligence system has solved a longstanding mathematics problem tied to the legendary Hungarian mathematician Paul Erdos, sparking fresh debate about the need for guardrails in AI research. The achievement marks a milestone in AI's ability to tackle abstract mathematical reasoning that has stumped humans for decades. Science experts are now calling for new frameworks to oversee AI-driven discoveries, as concerns grow about the pace of AI advancement outpacing oversight. The breakthrough was reported by Science News.
Using the James Webb Space Telescope, astronomers led by the University of Texas at Austin have obtained the deepest spectrum ever taken of 'little red dots' — faint, red objects from the early universe. The findings provide the strongest case yet that these objects are 'black hole stars,' a theoretical type of star powered by a central black hole rather than nuclear fusion. The discovery could reshape our understanding of how the first galaxies formed after the Big Bang.
The world's first vaccine designed entirely by artificial intelligence has entered human testing, marking a milestone in medical science. In other science news, the dismantling of a key ocean monitoring network raises fears of a US retreat from marine science. A satellite demonstrated the ability to identify objects autonomously in orbit using onboard AI.
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.
