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.....»»
Pickier dogs found to have pickier brains
Dogs' food preferences are mirrored in their brain activity, particularly within their caudate nuclei -a brain region associated with reward processing, a new study combining behavioral and neuroimaging data by researchers from the Department of Etho.....»»
Astronomers inspect supernova remnants with MeerKAT
Using the MeerKAT radio telescope, astronomers from the National Radio Astronomy Observatory (NRAO) in Charlottesville, Virginia, and elsewhere have investigated a batch of 36 high latitude supernova remnants. Results of the observations campaign, pu.....»»
Theoretical work indicates that the future Electron Ion Collider can be used to measure the shape of atomic nuclei
Scientists have developed a new way to study the shapes of atomic nuclei and their internal building blocks. The method relies on modeling the production of certain particles from high-energy collisions of electrons with nuclear targets. Such collisi.....»»
In California, 600 years" worth of tree rings reveal climate risks
An interdisciplinary collaboration used 600 years' worth of tree rings from the San Joaquin Valley to reconstruct plausible daily records of weather and streamflow scenarios during that period. Modeling based on those scenarios revealed the region ha.....»»
Physicists discover molecule-like structure of nuclear ground state
Scientists from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS), along with their collaborators, have recently discovered a molecular-type structure in the ground state of atomic nuclei. The study was published in Physi.....»»
LHCb: Correlations show nuances of the particle birth process
High-energy ion collisions at the Large Hadron Collider are capable of producing a quark-gluon plasma. But are heavy atomic nuclei really necessary for its formation? And above all: how are secondary particles later born from this plasma? Further clu.....»»
Understanding charged particles helps physicists simulate element creation in stars
New research from North Carolina State University and Michigan State University opens a new avenue for modeling low-energy nuclear reactions, which are key to the formation of elements within stars. The research lays the groundwork for calculating ho.....»»
Facilitating learning chemistry with conceptual modeling
A team of researchers and teachers from the University of Twente have developed a novel teaching method that uses conceptual modeling to facilitate learning and foster creativity in classrooms of chemical science and engineering students. The student.....»»
Carbon neutrality likely to increase extreme weather events by 2050, finds study
Climate modeling based upon Earth's current greenhouse gas emissions trajectory predicts a worst-case scenario of 4.3°C warming of the planet by 2100 if sufficient measures are not implemented. While the Paris Climate Agreement has been adopted by 1.....»»
Forest modeling shows which harvest rotations lead to maximum carbon sequestration
Forest modeling by Oregon State University scientists shows that a site's productivity—an indicator of how fast trees grow and how much biomass they accumulate—is the main factor that determines which time period between timber harvests allows fo.....»»
Investigating the contribution of gamma-ray blazar flares to neutrino flux
Blazars belong to the family of active galactic nuclei called quasars. What differentiates them from quasars is that the flares ejected out of these active galactic nuclei are pointed toward the Earth. These flares contain high-energy cosmic rays whi.....»»
Gamma-ray burst charged Earth’s ionosphere from 2 billion light-years away
The brightest supernova ever detected altered the outer layers of Earth's atmosphere. Enlarge / Artist's conception of a gamma-ray burst. (credit: NASA) An astounding gamma-ray burst, dubbed GRB 221009A, continues to ama.....»»
Deep dive on sea level rise: New modeling gives better predictions on Antarctic ice sheet melt
Using historical records from around Australia, an international team of researchers have put forward the most accurate prediction to date of past Antarctic ice sheet melt, providing a more realistic forecast of future sea level rise......»»
New research suggests plants might be able to absorb more CO2 from human activities than previously expected
New research published in Science Advances paints an uncharacteristically upbeat picture for the planet. This is because more realistic ecological modeling suggests the world's plants may be able to take up more atmospheric CO2 from human activities.....»»
Community-driven analysis identifies strategies to improve equity in Los Angeles" clean energy transition
After two years of robust modeling and gathering input from over 100 community members, 14 community-based organizations, and 31 additional stakeholder organizations in Los Angeles, the U.S. Department of Energy's National Renewable Energy Laboratory.....»»
Wildlife-vehicle collisions study delves into factors that impact detecting animals after dark
According to a 2008 study, wildlife-vehicle collisions cost an estimated $8.4 billion in damages, with more than 58,000 people injured and 440 deaths occurring annually. These numbers continue to increase as urban sprawl expands and human–wildlife.....»»
Satellite data can help limit the dangers of windblown dust
Interstate 10, an artery that cuts through the rural drylands of southern New Mexico, is one of the country's deadliest roadways. On one stretch of the highway, just north of a dry lakebed called Lordsburg Playa, fatal collisions occur with such regu.....»»
Modeling shows how wolves recolonized Germany and where they could live in the future
The return of the gray wolf (Canis lupus) to Germany, which began 23 years ago in the region of Lusatia in Eastern Germany, is a process of great ecological and social significance. Therefore, a precise understanding of the recolonization of the orig.....»»
A supernova devastated our ozone in 2022, new study reveals
