Particle accelerators reveal the heart of nuclear matter by smashing together atoms at close to the speed of light. The high-energy collisions produce a shower of subatomic fragments that scientists can then study to reconstruct the core building blocks of matter. Source link

Using X-ray lasers, researchers at Stockholm University have been able to determine the existence of a critical point in supercooled water at around -63 °C and 1,000 atmospheres. Ordinary water at higher temperatures and lower pressures is strongly affected by the presence of this critical point, causing the origin of its strange properties. The findings

A new independent measurement by the CMS experiment at the LHC is consistent with the existence of the most massive composite particle ever observed, the momentary union of a top quark and its antiquark Source link

For the first time, a team of physicists in Austria has carried out an experiment that appears to verify the principle of indefinite causal order: an idea that suggests that timelines of events can exist in multiple orders at the same time. Led by Carla Richter at the Vienna Center for Quantum Science and Technology,

Their mass is extremely low, but how light are neutrinos really? A collaboration comprising German and international research groups has optimized its experiments to determine the mass of these “ghost particles.” In doing so, they succeeded in further adjusting downward the upper limit on the neutrino mass scale that had previously been determined in similar

For decades, it has been widely believed that electrons move most efficiently in materials that are clean and highly ordered. Much like water flowing more easily through a smooth pipe, conventional wisdom has held that electrical transport improves as a material’s internal structure becomes more perfectly arranged. However, a recent study shows that the opposite

A fascination with fish gills has led researchers at Cornell to develop a bio-inspired approach to mixing heat and molecules in fluids—findings that could inform future biomedical devices, heat exchangers and soft robotics. Source link

Scientists in Geneva took some antiprotons out for a spin—a very delicate one—in a truck, in a never-tried-before test drive that has been deemed a success. Source link

The ALICE Collaboration takes a step further in addressing the question of whether a quark–gluon plasma can be formed in proton–proton and proton–nucleus collisions. In the first few microseconds after the Big Bang, the universe was in an extremely hot and dense state of matter known as quark–gluon plasma (QGP), which can be reproduced with
