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.....»»
New insights into neutrino interactions
Research at Hokkaido University has revealed that elusive particles called neutrinos can interact with photons, the fundamental particles of light and other electromagnetic radiation, in ways not previously detected. The findings from Kenzo Ishikawa,.....»»
Model shows life-threatening heat events will happen more often and in more places as the world warms
A team of climate scientists at the Woodwell Climate Research Center in the U.S., working with a colleague from the Environmental Change Institute in the U.K., has found via climate modeling that many more life-threatening heat events are likely to h.....»»
Artificial Intelligence: A step change in climate modeling predictions for climate adaptation
As of today, climate models face the challenge of providing the high-resolution predictions—with quantified uncertainties—needed by a growing number of adaptation planners, from local decision-makers to the private sector, who require detailed as.....»»
Did this supernova explode twice?
All supernovae are exploding stars. But the nature of a supernova explosion varies quite a bit. One type, named Type 1a supernovae, involves a binary star where one of the pair is a white dwarf. And while supernovae of all types usually involve a sin.....»»
Webb reveals new structures within iconic supernova
NASA's James Webb Space Telescope has begun the study of one of the most renowned supernovae, SN 1987A (Supernova 1987A). Located 168,000 light-years away in the Large Magellanic Cloud, SN 1987A has been a target of intense observations at wavelength.....»»
James Webb telescope captures stunning view of a famous supernova remnant
The James Webb Space Telescope has provided one of the most detailed views yet of the stunning supernova remnant SN 1987A, created from a destructive explosion......»»
New giant planet shows evidence of possible planetary collisions
A Neptune-sized planet denser than steel has been discovered by an international team of astronomers, who believe its composition could be the result of a giant planetary clash......»»
Exploring light neutron-rich nuclei: First observation of oxygen-28
The study of physical systems under extreme conditions offers valuable insights into their organization and structure. In nuclear physics, neutron-rich isotopes, especially the light ones with neutron-to-proton ratio significantly different from that.....»»
Climate models suggest curbing air pollution helps newly planted trees reduce local temperature
A team of meteorologists and atmospheric scientists at Nanjing University, in China, has found via modeling that planting trees in certain areas to reduce local temperatures is more effective if air pollution levels are reduced. In their study, repor.....»»
Closest supernova in a decade reveals how exploding stars evolve
Alex Filippenko is the kind of guy who brings a telescope to a party. True to form, at a soiree on May 18 this year, he wowed his hosts with images of star clusters and colorful galaxies—including the dramatic spiral Pinwheel Galaxy—and snapped t.....»»
New supernova remnant detected with ASKAP
Using the Australian Square Kilometer Array Pathfinder (ASKAP), an international team of astronomers has serendipitously detected a new Galactic supernova remnant (SNR), which received designation SNR G288.8–6.3. The finding was reported in a paper.....»»
The first observation of neutrinos at CERN"s Large Hadron Collider
Neutrinos are tiny and neutrally charged particles accounted for by the Standard Model of particle physics. While they are estimated to be some of the most abundant particles in the universe, observing them has so far proved to be highly challenging,.....»»
James Webb Space Telescope survey reveals fewer supermassive black holes than presumed
A University of Kansas survey of a swath of the cosmos using the James Webb Space Telescope has revealed active galactic nuclei (AGN)—supermassive black holes that are rapidly increasing in size—are rarer than many astronomers had assumed previou.....»»
New modeling method could drive better understanding of extreme heat waves
To prepare for extreme heat waves around the world—particularly in places known for cool summers—climate-simulation models that include a new computing concept may save tens of thousands of lives......»»
GM"s Cruise slashed fleet of robotaxis by 50% in San Francisco after collisions
California authorities have asked General Motors to "immediately" take some of its Cruse robotaxis off the road after autonomous vehicles were involved in two collisions -- including one with an active fire truck -- last week in San Francisco......»»

Models suggest Grand Canyon could see increase in heat-related illnesses due to climate change
A pair of resource stewardship researchers at the U.S. National Park Service's, Natural Resource Stewardship and Science Directorate, working with a colleague from the University of Pennsylvania, has found via modeling that it is likely more visitors.....»»
Modeling the future of glaciers and the new ecosystems that will develop as deglaciation occurs
A team of geologists and geoscientists affiliated with several institutions in Switzerland and two in France, has created a model designed to predict the amount of glacier loss up to the year 2100 and the ecosystems that will arise in their place......»»
Surprisingly deadly summer for Lake Tahoe bears: 20 killed, 18 hurt in vehicle collisions
Twenty bears killed and almost 20 more injured—it's been a uniquely dangerous summer for Lake Tahoe's bear population, with more hit by vehicles from late July to mid-August "than we've ever had at that time," said Ann Bryant of the Bear League......»»
Using supernovae to study neutrinos" strange properties
In a new study, researchers have taken an important step toward understanding how exploding stars can help reveal how neutrinos, mysterious subatomic particles, secretly interact with themselves......»»
