Phys.org / Virtual cells built from 4D AI models and 'digital twins' could speed up drug discovery
Mitochondria—tiny structures that convert nutrients into energy—are often depicted as discrete kidney bean-shaped objects. But in reality, they form a dynamic, interconnected network throughout the entire cell, rapidly splitting ...
Phys.org / Two-color light steers electrons through graphene's transient topological state
The electronic properties of materials are typically determined by their structure under normal, undisturbed conditions, when they are in a state known as equilibrium. Intense light beams, however, can temporarily reshape ...
Phys.org / The monsters that weren't: Dinosaur and tusked-beast claims in San rock art unravel
For decades, an idea has grown in paleontology that, long before scientists began digging up and reconstructing dinosaur bones, the Indigenous San and Basotho in southern Africa noticed them too, incorporating them into songs, ...
Phys.org / Global population dataset uses buildings to reveal people's daily movement patterns
Researchers at the Department of Energy's (DOE) Oak Ridge National Laboratory (ORNL) have released LandScan Mosaic, a next-generation global population distribution dataset that estimates where people are by modeling how ...
Phys.org / Loss of Y chromosome in men could be an early warning sign of cancer
A study initiated by Dr. Dan Theodorescu, a physician-scientist at the University of Arizona Cancer Center, revealed that the loss of the Y chromosome in men's body tissue could pave the way for cancer to develop. According ...
Phys.org / How the malaria parasite boosts its transmission potential under stress conditions
The malaria parasite is able to detect changes in its host's environment and respond by increasing the production of sexual forms capable of being transmitted to mosquitoes. A study led by the Barcelona Institute for Global ...
Phys.org / A molecular bridge connects two signaling pathways critical for pollen development
Cells rely on complex signaling networks in which different molecular pathways communicate with one another. Small GTPases act as molecular switches in these networks, controlling diverse cellular processes such as intracellular ...
Phys.org / Scientists simulate cosmic crashes to test whether icy moons gain or lose their ability to sustain life
Many of the moons orbiting Saturn, Uranus and Neptune likely conceal oceans of liquid water beneath miles of icy shell. Because life as we know it needs water, these buried oceans rank among the most promising places to search ...
Phys.org / Protein map reveals how red blood cells rapidly adjust to low oxygen
Scientists map the hidden protein network that helps red blood cells adapt to oxygen
Phys.org / Physicists extend the search for quantum black holes at the LHC
Physicists at UC Santa Barbara have extended the search for evidence of microscopic black holes produced at the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN). The formation of these ...
Phys.org / Greenland's Qaanaaq Ice Cap has lost enough ice to produce a layer of water about 8 meters deep
Each summer, researchers from Hokkaido University returned to the Qaanaaq Ice Cap in northwestern Greenland to measure changes in the ice surface using aluminum poles drilled into the ice. Their 13-year record shows how the ...
Phys.org / Medieval Chinese skeleton may reveal first evidence of a brutal punishment
Ancient Chinese authorities used many creative ways to punish people, often with methods designed to mark them for life. One brutal example mentioned repeatedly in historical texts is cutting off a person's nose. However, ...
