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.....»»
Ticking time bomb: New modeling predicts huge increase in ticks across Scotland
The prevalence of ticks in Scotland will increase by a quarter under the most optimistic climate change scenario, according to new modeling by mathematicians at the University of Stirling......»»
Astronomers explain rapid formation of organic macromolecules in protoplanetary disks around young stars
An international team of researchers led by the University of Bern has used observation-based computer modeling to find an explanation for how macromolecules can form in a short time in disks of gas and dust around young stars. These findings could b.....»»
Madison Symmetric Torus operates stable plasma at 10 times the Greenwald Limit
If net-positive fusion energy is to ever be achieved, density is key: the more atomic nuclei crashing into each other, the more efficient the reaction will be. Nearly 40 years ago, Martin Greenwald identified a density limit above which tokamak plasm.....»»
New research offers insight on modeling belief dynamics
Researchers who study belief dynamics often use analogies to understand and model the complex cognitive–social systems that underlie why we believe the things we do and how those beliefs can change over time. Ideas can be transmitted like a virus,.....»»
NASA returns to Arctic to study summer sea ice melt
What happens in the Arctic doesn't stay in the Arctic, and a new NASA mission is helping improve data modeling and increasing our understanding of Earth's rapidly changing climate. Changing ice, ocean, and atmospheric conditions in the northernmost p.....»»
AI and ML enter motorsports: How GM is using them to win more races

High-energy collision study reveals new insights into quark-gluon plasma
In high-energy physics, researchers have unveiled how high-energy partons lose energy in nucleus-nucleus collisions, an essential process in studying quark-gluon plasma (QGP). This finding could enhance our knowledge of the early universe moments aft.....»»
Scientists say sun"s influence penetrates into deep Earth
For years, scientists believed that changes in the Earth's interior, such as volcanic eruptions and tectonic plate collisions, primarily affected the surface environment. Events such as the mass extinction around 66 million years ago and the transiti.....»»
Scientists resolves a long-debated anomaly in how nuclei spin
Atomic nuclei come in different shapes, varying from football-like ("prolate") to pancake-like ("oblate"). Prolate and oblate shapes have different moments of inertia. This is a body's resistance to having its speed of rotation altered by an external.....»»
3D visualization brings nuclear fusion to life
When it comes to promising forms of energy, nuclear fusion checks all the boxes: it's clean, abundant, continuous and safe. It's produced when the lightweight nuclei of two atoms fuse together to form a heavier nucleus, releasing large amounts of ene.....»»
Scientists add the human element to long-term flood predictions
To better predict long-term flooding risk, scientists at the Department of Energy's Oak Ridge National Laboratory developed a 3D modeling framework that captures the complex dynamics of water as it flows across the landscape. The framework seeks to p.....»»
First observation of the nuclear two-photon decay in bare atomic nuclei
For the first time, an international research team has succeeded in observing a two-photon decay on a so-called bare atomic nucleus from which the entire electron shell has been removed......»»
Researchers reveal parsec-scale radio emission properties of dual AGNs by multi-phase-center VLBI observations
Galaxy mergers play a crucial role in the cosmological evolution of galaxies. During galaxy merging, tidal torques can trigger the accretion and feedback of the central black holes in merging galaxies, forming dual active galactic nuclei (AGNs)......»»
Powerful new particle accelerator a step closer with muon-marshaling technology
New experimental results show particles called muons can be corralled into beams suitable for high-energy collisions, paving the way for new physics......»»
How climate change is altering the Earth"s rotation
For the first time, researchers at ETH Zurich have been able to fully explain the various causes of long-term polar motion in the most comprehensive modeling to date, using AI methods. Their model and their observations show that climate change and g.....»»
Researchers directly simulate the fusion of oxygen and carbon nuclei
The fusion of two nuclei is a complex process influenced by many factors. These factors include not only the relative energy and angular momentum of the two nuclei, but also how their structures evolve as they collide. The outcome of the collisions i.....»»
Webb unveils stunning ejecta and CO structures in Cassiopeia A"s young supernova
The SETI Institute announced the latest findings from the James Webb Space Telescope (JWST) of the supernova remnant, Cassiopeia A (Cas A). These observations of the youngest known core collapse supernova in the Milky Way provide insights into the co.....»»
Hubble measures the distance to a supernova
Measuring the distance to truly remote objects like galaxies, quasars, and galaxy clusters is a crucial task in astrophysics, particularly when it comes to studying the early universe, but it's a difficult one to complete......»»
What flavor is that neutrino? Adding flavor helps to track neutrino movement in astrophysical systems
Neutrinos have a quantum mechanical property called "flavor." This flavor can transform as neutrinos move through space. A major challenge is to keep track of both the physical movement of the neutrinos and their change of flavor in astrophysical sys.....»»
Research team models connection between enzyme activity and yields for the first time
