Medical Xpress / Brain chemistry can reactivate or suppress dormant HIV
Human immunodeficiency virus (HIV) infections are still fairly common and an estimated 40 million people worldwide are currently living with this condition. The HIV virus attacks the body's immune system and thus makes those ...
Phys.org / Scientists chart over 140,000 DNA loops to map human chromosomes in the nucleus
One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published in Nature.
Medical Xpress / Stiffer colon could signal risk of early-onset colorectal cancer
Increased stiffness of the colon, spurred by chronic inflammation, may encourage the development and progression of early-onset colorectal cancer (CRC), a study co-led by UT Southwestern Medical Center researchers suggests. ...
Phys.org / Two ancient human species came out of Africa together, not one, suggests new study
The textbook version of the "Out of Africa" hypothesis holds that the first human species to leave the continent around 1.8 million years ago was Homo erectus. But in recent years, a debate has emerged suggesting it wasn't ...
Phys.org / Saturn's icy moon Enceladus is an attractive target in the search for life—new research
A small, icy moon of Saturn called Enceladus is one of the prime targets in the search for life elsewhere in the solar system. A new study strengthens the case for Enceladus being a habitable world.
Phys.org / The simulation hypothesis: Mathematical framework redefines what it means for one universe to simulate another
The simulation hypothesis—the idea that our universe might be an artificial construct running on some advanced alien computer—has long captured the public imagination. Yet most arguments about it rest on intuition rather ...
Medical Xpress / How natural daylight can help people with diabetes improve blood sugar levels
People with type 2 diabetes may be able to improve their blood sugar by doing something as simple as sitting by a window for a few hours each day. In a study published in Cell Metabolism, scientists showed that natural daylight ...
Tech Xplore / All-optical chip achieves 100-fold speed boost over top-tier NVIDIA chips
Scientists in China have unveiled a new AI chip called LightGen that is 100 times faster and 100 times more energy efficient than NVIDIA chips, the leading supplier of AI chips worldwide. Instead of using electricity to move ...
Phys.org / Arctic sea ice melt slowdown since 2012 linked to atmospheric pattern shift
A research team led by The Hong Kong University of Science and Technology (HKUST) scholars has discovered a significant slowdown in Arctic sea ice melting since 2012, with a decrease rate of 11.3% per decade to an insignificant ...
Medical Xpress / Not thinking about anything: Toward a brain signature of mind blanking
When we are awake, we seem to experience a continuous stream of sensations, reflections, memories, and impressions that make up our mental life. Yet some people report moments when they think about nothing at all. Is that ...
Medical Xpress / A urine-based biological aging clock: Machine learning and microRNA offer accurate prediction
Craif Inc. in Nagoya, Japan, working with Nagoya University's Institute of Innovation for Future Society, has developed a urine-based biological aging clock. In validation of the method, predicted ages came within 4.4 years ...
Phys.org / Kolmogorov-Arnold networks bridge AI and scientific discovery by increasing interpretability
AI has successfully been applied in many areas of science, advancing technologies like weather prediction and protein folding. However, there have been limitations for the world of scientific discovery involving more curiosity-driven ...
