8+ hour, 22+ min ago   (1053+ words) Ivy Delaney has been working with neural networks and machine learning since the mid-nineties, back when a couple of hidden layers and a long afternoon of training counted as ambitious. She has watched the field go from academic curiosity to…...

8+ hour, 4+ min ago   (620+ words) The stands will house superconducting magnets previously used to guide beams around the collider. A US student has designed massive storage stands that are capable of supporting up to 45,000 pounds of superconducting magnets for the world’s first electron-ion collider (EIC)....

15+ hour, 47+ min ago   (804+ words) Ivy Delaney has been working with neural networks and machine learning since the mid-nineties, back when a couple of hidden layers and a long afternoon of training counted as ambitious. She has watched the field go from academic curiosity to…...

19+ hour, 53+ min ago   (359+ words) The Hubble constant determines the rate at which the Universe is expanding. Today, scientists try to calculate it in two fundamentally different ways: The difference between 67 and 73 may seem small. But given the high precision of the instruments, it is…...

1+ day, 10+ hour ago   (262+ words) In the United States, the STAR experiment at the Relativistic Heavy Ion Collider RHIC recorded an unexpected pattern in particles produced after collisions of gold nuclei at speeds close to the speed of light. Researchers found a decline in correlations…...

1+ day, 15+ hour ago   (720+ words) A particle collider experiment just revealed something unexpected about how the fiery soup of particles that filled the universe after the Big Bang coalesced into the protons and neutrons that make up matter today. Physicists smashed gold nuclei together at…...

2+ day, 9+ hour ago   (232+ words) Dr. Donovan is a futurist and technology writer covering the quantum revolution. Where classical computers manipulate bits that are either on or off, quantum machines exploit superposition and entanglement to process information in ways that classical physics cannot. Dr. Donovan…...

3+ day, 13+ hour ago   (596+ words) In the early 1930s, scientists were just beginning to discover the extraordinary world hidden inside the atom, which is made up of a dense center, called the nucleus, with electrons orbiting around it. Cockcroft and Walton wondered whether they could instead…...

3+ day, 9+ hour ago   (477+ words) Superman’s X-ray vision isn’t actually that super. X-rays work well for seeing through thin objects or medical scans, but thick concrete walls and dense lead shields block them completely. Physicists have found a solution in muons, which are heavy subatomic…...

3+ day, 11+ hour ago   (330+ words) Nuclear parton distribution functions are surprising because the energy needed to bind the nucleon inside the nucleus is tiny when compared to that needed to resolve the partons. Researchers at the ATLAS Collaboration at the CERN have found the origins…...
