Modeling collisions between argon nuclei and neutrinos from a supernova
Massive stars end their lives in explosions called core-collapse supernovae. These explosions produce very large numbers of weakly interacting particles called neutrinos. Scientists working on the Deep Underground Neutrino Experiment, hosted by Fermi.....»»
NASA telescopes start the year with a double bang
A colorful, festive image shows different types of light containing the remains of not one, but at least two exploded stars. This supernova remnant is known as 30 Doradus B (30 Dor B for short) and is part of a larger region of space where stars have.....»»
Study shows 3D organization of DNA controls cell identity programs
In a complex called chromatin, long strands of DNA in cells' nuclei are tightly wrapped around a scaffolding of proteins, like a rolled-up ball of yarn. A new study by Weill Cornell Medicine investigators reveals that beyond providing a convenient wa.....»»
A dense quark liquid is distinct from a dense nucleon liquid
Atomic nuclei are made of nucleons (like protons and neutrons), which themselves are made of quarks. When crushed at high densities, nuclei dissolve into a liquid of nucleons and, at even higher densities, the nucleons themselves dissolve into a quar.....»»
Researchers find natural spa water in central Japan is long-trapped lithospheric water
Researchers at the University of Tsukuba have made a groundbreaking discovery regarding the origins of non-meteoric water in natural spa waters located in central Japan. Based on numerical modeling, their results suggest that this water has been conf.....»»
Ordering of neutrino masses may be revealed by measuring those produced in Earth"s atmosphere
A group of physicists, three with Harvard University's Department of Physics and Laboratory for Particle Physics and Cosmology, and the fourth with the University of Liverpool, has found evidence suggesting that additional measurements of neutrinos g.....»»
Many models are better than one for COVID-19 scenario projections, study finds
During the COVID-19 pandemic, the COVID-19 Scenario Modeling Hub generated look-ahead projections for COVID-19 cases, hospitalizations and deaths under specific, policy-relevant scenarios. Those projections were provided to federal agencies such as t.....»»
Webb spots a second lensed supernova in a distant galaxy
In November 2023, the James Webb Space Telescope observed a massive cluster of galaxies named MACS J0138.0-2155. Through an effect called gravitational lensing, first predicted by Albert Einstein, a distant galaxy named MRG-M0138 appears warped by th.....»»
Collision, braking tech struggle to prevent crashes with large trucks, motorcycles
The institute's study of more than 160,000 crashes found that front crash prevention systems reduced rear-end collisions with medium- or heavy-duty trucks by 38 percent and with motorcycles by 41 percent......»»
How do quark-gluon-plasma fireballs explode into hadrons?
Quark gluon plasma (QGP) is an exciting state of matter that scientists create in a laboratory by colliding two heavy nuclei. These collisions produce a QGP fireball. The fireball expands and cools following the laws of hydrodynamics, which govern ho.....»»
New nuclear deflection simulations advance planetary defense against asteroid threats
Researchers at Lawrence Livermore National Laboratory (LLNL) have developed a modeling tool for assessing the potential use of a nuclear device to defend the planet against catastrophic asteroid impacts......»»
AI models predict decay modes and half-lives of superheavy nuclei with unprecedented accuracy
In a study published in the journal of Nuclear Science and Techniques, researchers from Sun Yat-sen University have achieved a significant breakthrough in understanding the decay processes of superheavy nuclei. Their pioneering study, employing a ran.....»»
New technique could make modeling molecules much easier
Much like the humans that created them, computers find physics hard, but quantum mechanics even harder. But a new technique created by three University of Chicago scientists allows computers to simulate certain challenging quantum mechanical effects.....»»
A new mathematical language for biological networks
A team of researchers around Berlin mathematics professor Michael Joswig is presenting a novel concept for the mathematical modeling of genetic interactions in biological systems. Collaborating with biologists from ETH Zurich and Carnegy Science (U.S.....»»
Morocco earthquake had unusual deep slip, according to new modeling
In their rapid characterization of the magnitude 6.8 Al Haouz earthquake in Morocco, researchers from the U.S. Geological Survey's National Earthquake Information Center (NEIC) suggest that the earthquake ruptured roughly 25 kilometers deep beneath t.....»»
Biodiversity modeling advances to improve predictions of nature"s contributions to people
People depend on nature in a multitude of ways. Crop pollination, pest management, storm buffering, and carbon capturing are all part of nature's contributions to people (NCP). But these contributions are subject to change—species that make vital c.....»»
Blender 4.0 released with new features and better Apple Silicon performance
Blender Foundation has released version 4 of the popular Blender 3D design app, bringing interface changes, feature improvements, and most importantly speed boosts for Apple Silicon Macs.Blender is a leading 3D modeling application for Mac, Windows,.....»»
James Webb provides a second view of an exploded star
A beautiful supernova remnant, Cassiopeia A, was recently imaged by the James Webb telescope. See how the observation compares to a previous MIRI image......»»
U.S. awards $110 million to reduce wildlife car collisions
There are more than 1 million wildlife vehicle collisions in the U.S. with large animals like deer that cost more than $8 billion annually......»»
Collisions change how fast ions surf on plasma waves in fusion experiments and beyond
Just like there are waves in the ocean, waves can also occur in an electrically charged gas called a plasma, made up of electrons and ions. In the ocean, people surf by riding their boards at nearly the same speed as the waves. This matching conditio.....»»
Prototype for DUNE detector will test new technology that can handle more neutrinos
Long before the Deep Underground Neutrino Experiment takes its first measurements in an effort to expand our understanding of the universe, a prototype for one of the experiment's detectors is blazing new trails in neutrino detection technology......»»
