Phys.org / AI diffusion models tailor drug molecules to custom-fit protein targets, speeding drug development and evaluation
University of Virginia School of Medicine scientists have developed a bold new approach to drug development and discovery that could dramatically accelerate the creation of new medicines. UVA's Nikolay V. Dokholyan, Ph.D., ...
Phys.org / Medieval Japanese poetry and buried trees help elucidate volatile space weather
On Earth, extreme solar activity often appears as beautiful, benign auroras. But venturing beyond the safety of the Earth's magnetic field, one faces the full brunt of a temperamental star that can suddenly erupt with flares ...
Phys.org / Dragonflies share humans' red-light sensing trick, detecting wavelengths near 720 nm
Sometimes, different organisms can evolve the same ability independently, a process called parallel evolution. A new study from Osaka Metropolitan University (OMU) has found that dragonflies sense red light similarly to mammals, ...
Phys.org / Hat wars of early modern England reveal how manners make the rebel
From refusing to doff hats in court to resisting hat-snatching highway robbers, England's relationship with hats goes far deeper than fashion, new research shows.
Phys.org / Single-shot imaging captures more information about ultrafast microscopic processes than previously possible
Researchers have developed a new imaging technique that captures more information about ultrafast processes in the microscopic world than was previously possible. The technique offers scientists a powerful new tool to observe ...
Phys.org / One DNA letter can trigger complete sex reversal
Researchers at Bar-Ilan University have discovered that changing just one letter in DNA can completely alter sex development in mice. In the new study, published in Nature Communications, a single-letter insertion in a non-coding ...
Phys.org / Liquid-like histone H1 'glues' nucleosomes, reshaping how DNA compacts
DNA inside the nucleus is not packed as a rigid regular fiber—linker histone H1 dynamically binds and loosely "glues" nucleosomes together, creating a dynamic, fluid organization that can still support essential genome functions.
Phys.org / Carbon nanotube fiber sensors achieve record measurement error below 0.1%
Skoltech scientists, in collaboration with colleagues from China and Iran, have taken a major step toward creating highly precise carbon nanotube fiber (CNTF)-based sensors. In a paper published in the iScience journal, the ...
Phys.org / Nickel catalyst enables precision mirror-image assembly for key drug scaffolds
A research team led by Prof. Sangwon Seo of the Department of Physics and Chemistry at DGIST has developed a catalytic technology that can easily and elaborately assemble key structural frameworks that serve as the scaffold ...
Phys.org / Houston, we have a problem ... with the toilet
After a successful trip around the moon, everything has been going smoothly on the Orion spacecraft's journey back to Earth—except for the $23 million toilet, which has gotten clogged.
Phys.org / Deadly heat thresholds have already being crossed in six recent heat waves, study shows
Deadly heat wave events are occurring at temperatures and humidity levels previously thought to be survivable, according to a new paper by a team of international researchers, including from The Australian National University ...
Phys.org / Street green space can help cool cities, but it will not be enough on its own
A new IIASA-led study finds that expanding street green space can reduce urban heat stress in cities worldwide, but even ambitious greening efforts are unlikely to offset a significant share of the additional heat expected ...
