Phys.org / Parental care can influence evolution, beetle experiments show
How has offspring dependence on parents evolved over the course of evolution? Researchers at the University of Bayreuth, in collaboration with Kyoto University, Japan, have investigated one possible mechanism by studying ...
Phys.org / Roman telescope aims to directly image exoplanets 1,000 times fainter than current limits
The Roman Space Telescope is designed to directly image exoplanets using complex optomechanical systems developed by the Max Planck Institute for Astronomy
Phys.org / XY or ZW? Gecko chromosomes reveal evolution's hidden playbook
Why do humans rely on XY chromosomes to determine sex, while birds use ZW—and many reptiles use neither, letting temperature decide instead? Sex determination is remarkably diverse across the animal kingdom. In genotypic ...
Phys.org / MOF-coated catalyst converts CO₂ to CO nearly five times faster under ultrasonic vibration
Researchers at the University of Osaka have developed a catalyst that uses mechanical vibration to convert carbon dioxide (CO2) into carbon monoxide (CO), an important chemical feedstock. The catalyst consists of barium titanate ...
Medical Xpress / Txn1 mutant rats: A valuable translational model of chronic kidney disease
Chronic kidney disease (CKD) is a major health burden affecting approximately one in 10 adults globally. Even with improved treatments, many patients continue to experience worsening kidney function, resulting in the need ...
Medical Xpress / Brain activity patterns may 'tag' experiences for later memory-making during sleep
The brain may "tag" experiences during learning to better consolidate memories of them during sleep, according to a study published Aug. 27 in the journal PLOS Biology by Dan Denis from the University of York, United Kingdom, ...
Phys.org / Shear flow in narrow channels sparks amyloid formation, experiments reveal
Many cars and not enough lanes is a recipe for traffic jams. Now, researchers from Japan show that even proteins can get backed up and start behaving poorly when too many try to squeeze too quickly through a small space.
Phys.org / Cowpea plants create underground defense system for the next generation after insect attacks
Plants might seem helpless when it comes to insect attacks, but they are known to employ various techniques to deter pests. One of these techniques involves sending out signals to recruit parasitoid wasps, and a new study, ...
Phys.org / Oxygen collisions reveal how quark–gluon matter approaches equilibrium
High-energy nuclear collisions recreate extreme conditions similar to those in the early universe, producing quark–gluon plasma (QGP), a hot state of matter in which quarks and gluons are no longer confined inside protons ...
Phys.org / A 4-star system caught eclipsing itself in a way never seen before
Astronomers have found a four-star system doing something that has never been confirmed before. The system, TIC 433545934, has two close pairs of stars orbiting each other. While each pair eclipses its own two stars, as usual, ...
Medical Xpress / Pre-cancerous blood cells may fuel disease risk by prematurely aging the bone marrow
Precancerous blood cells can actively reshape their surroundings, prematurely aging cells in the bone marrow to create conditions that favor their own growth and potentially increase the risk of blood cancer, according to ...
Medical Xpress / Macrophage 'molecular scissors' may drive obesity-linked inflammation and metabolic damage
Imagine the body's immune cells as a neighborhood cleanup crew. When all is healthy, macrophages roam tissues, clearing away cellular debris and helping maintain order. But obesity can turn these normally protective cells ...
