Phys.org / A famous galaxy's black hole has been hiding its most violent behavior
Astronomers have found that a nearby galaxy's black hole is blasting out a far more powerful and hidden gas outflow than previously realized. Studying NGC 1068, a well-known galaxy with an actively feeding black hole at its ...
Phys.org / Earth's atmosphere is getting less dusty: That could be adding to global warming
Atmospheric desert dust has long swirled around the globe, but a new UCLA study presents the strongest evidence yet that global dust is mysteriously decreasing. Because atmospheric dust has a slight overall cooling effect ...
Phys.org / Gravitational-wave analysis narrows the search for black hole impostors
Black holes are regions of spacetime where gravity is so strong that nothing, not even light, can escape. When two black holes orbit each other and merge, they produce gravitational waves (i.e., ripples in spacetime) that ...
Tech Xplore / 'We're losing control': AI pioneer urges nuclear-style safeguards for autonomous agents
The Canadian computer scientist Yoshua Bengio, considered one of the founders of AI, told AFP that humanity is "losing control" of the technology and that the world needs guardrails similar to nuclear arms controls.
Tech Xplore / Harvesting hot electrons could break solar panel barrier
Physics predicts that no more than 33% of the solar energy that falls on a solar panel can be converted into electricity. However, experiments and simulations by scientists at the University of Groningen in the Netherlands ...
Phys.org / Bone strength study reveals new clues about human evolution
Bipedalism, or walking on two legs, is one of the key features that distinguishes humans from other apes. But when and why our ancestors transitioned from a life often spent in trees to a life spent almost exclusively on ...
Phys.org / Anti-transgender legislation can cause psychological distress even in states with trans-friendly laws
Legislation that affects or discriminates against transgender and gender-diverse individuals can cause more psychological distress than personal experiences of discrimination, according to new Virginia Commonwealth University ...
Medical Xpress / AI tool nears psychiatrist-level accuracy
UTHealth Houston researchers have developed an artificial intelligence system that can perform a mental health evaluation at nearly the same level of accuracy as a team of psychiatrists. The results of their work, done in ...
Phys.org / Circular Rydberg atoms set three records, staying stable for 11 milliseconds
Rydberg atoms are considered promising building blocks for quantum computers and their precursors, quantum simulators. Researchers at the 5th Institute of Physics of the University of Stuttgart have achieved record values ...
Phys.org / Two spike 'keys' work together to let SARS-CoV-2 enter cells, study reveals
To enter cells, the COVID-19 virus fuses its surrounding membrane with the membrane of the target cell. This is where the fusion peptides of the spike protein come into play. These regions function as molecular keys that ...
Medical Xpress / Intermittent fasting shows promise in slowing Huntington's disease progression
A simple change in when people eat may offer a promising new approach for Huntington's disease, according to research led by Oregon Health & Science University.
Medical Xpress / Blood test shows promise for detecting pancreatic cancer at its earliest stages
Researchers at City of Hope, one of the largest and most advanced cancer research and treatment organizations in the country, led the development of a new investigational blood test that could detect pancreatic cancer at ...
