Detecting atmospheric rivers with satellite observations
Atmospheric rivers (ARs) are filaments of intense moisture transport in the atmosphere. These weather systems drive a large fraction of the extreme precipitation events over coastal regions. Detecting ARs in satellite observations has long been a cha.....»»
Atmospheric rivers are shifting poleward, reshaping global weather patterns
Atmospheric rivers—those long, narrow bands of water vapor in the sky that bring heavy rain and storms to the U.S. West Coast and many other regions—are shifting toward higher latitudes, and that's changing weather patterns around the world......»»
Astronomers observe a strong superflare from giant star
Using the Neutron Star Interior Composition Explorer (NICER) and various ground-based telescopes, an international team of astronomers have performed observations of a strong X-ray superflare which occurred in 2022 on a giant star known as HD 251108......»»
Eastern Pacific study highlights severe cold-water bleaching as an additional threat to deep reef ecosystems
Researchers from the Max Planck Institute for Chemistry (MPIC) recently published a paper detailing their observations of a major coral bleaching and mortality event that occurred on the deep reefs of the Clipperton Atoll, a remote coral island in th.....»»
A geomagnetic storm is hitting the northern part of the US. Here"s how the solar event may impact you
Warnings about Hurricane Milton hitting Florida have dominated news reports this week. But there have been warnings from forecasters with the U.S. National Oceanic and Atmospheric Administration's Space Weather Prediction Center about another storm b.....»»
Machine learning could improve extreme weather warnings
Because small changes in atmospheric and surface conditions can have large, difficult-to-predict effects on future weather, traditional weather forecasts are released only about 10 days in advance. A longer lead time could help communities better pre.....»»
First greenhouse gas plumes detected with NASA-designed instrument
The imaging spectrometer aboard the Carbon Mapper Coalition's Tanager-1 satellite has identified methane and carbon dioxide plumes in the United States and internationally......»»
Environmental factors influence Southeast Brazil"s coastal biodiversity more than ecological processes, study finds
Sea surface temperature, wave energy and freshwater discharge from rivers influence the abundance and size of the marine organisms that inhabit rocky shores along the coast of Southeast Brazil more than ecological processes such as competition and pr.....»»
Polar jet stream could reveal Saturn"s rotational period
A hexagon-shaped atmospheric phenomenon first spotted on Saturn by Voyager 1 and Voyager 2 has intrigued scientists since the 1980s. More recently, NASA's Cassini mission has periodically observed the hexagon and its embedded strong eastward jet that.....»»
Satellite data show massive bombs dropped in dangerous proximity to Gaza Strip hospitals in 2023
Satellite data on the proximity of hundreds of M-84 bomb craters to hospitals in the Gaza Strip suggest that, as of November 2023, hospitals were not being given special protection from indiscriminate bombing, as mandated by international humanitaria.....»»
Physics team uncovers a quantum Mpemba effect with a host of "cool" implications
Initially investigating out of pure curiosity, researchers have made a discovery that bridges the gap between Aristotle's observations two millennia ago and modern-day understanding, while opening the door to a whole host of "cool"—and "cooling"—.....»»
Hera probe heads off to see aftermath of DART"s asteroid impact
The European Space Agency's Hera spacecraft is on its way to do follow-up observations of Dimorphos, two years after an earlier probe knocked the mini-asteroid into a different orbital path around a bigger space rock......»»
PSA: Install iOS 18 with Messages via satellite for your Hurricane Milton prep
Hurricane Milton currently looks like an extremely dangerous threat to the state of Florida. If you are in Milton’s path, or you know someone who is, there’s a key piece of hurricane prep I highly recommend: install iOS 18 so you can start using.....»»
Detecting Planck-scale dark matter by leveraging quantum interference
While various studies have hinted at the existence of dark matter, its nature, composition and underlying physics remain poorly understood......»»
Physicists and psychologists track social phases in human movement
Observations of preschool children in classrooms and playgrounds have uncovered new social phases in human movement. Employing ultra-wideband radio frequency identification (UWB-RFID) technology allows for the precise tracking of children's movements.....»»
SOC teams are frustrated with their security tools
Security operations center (SOC) practitioners believe they are losing the battle detecting and prioritizing real threats – due to too many siloed tools and a lack of accurate attack signal, according to Vectra AI. They cite a growing distrust in v.....»»
Paper-based sensor offers rapid cardiac diagnostics in 15 minutes
In a significant advancement for point-of-care medical diagnostics, a team of researchers from UCLA has introduced a deep learning-enhanced, paper-based vertical flow assay (VFA) capable of detecting cardiac troponin I (cTnI) with high sensitivity. T.....»»
Large radio bubble detected in galaxy NGC 4217
An international team of astronomers has performed radio observations of a star-forming galaxy known as NGC 4217. The observational campaign detected a large radio bubble in the galaxy's halo. The finding was reported in a paper published September 2.....»»
Capturing finer-scale topographic differences improves Earth system model capability to reproduce observations
Earth system models (ESMs), used in climate simulations and projections, typically use grids of 50–200 km resolution. These are considered relatively coarse with limited ability to resolve land surface variability......»»
Antarctic "greening" at dramatic rate, satellite data show
Vegetation cover across the Antarctic Peninsula has increased more than 10-fold over the last four decades, new research shows......»»
New research uncovers how climate and soil shape tree and shrub wood density across ecosystems
An article published in Advances in Atmospheric Sciences has provided new insights into how wood density in trees and shrubs adapts to different climate and soil conditions. Led by Dr. Song Xiang from the Institute of Atmospheric Physics at the Chine.....»»
