Investigating dense plasmas with positron waves
Astrophysical and lab-created plasmas under the influence of magnetic fields are the source of intense study. New research seeks to understand the dynamics of position waves traveling through these clouds of highly ionized gas......»»
Researchers urge closing outdated water rule to aid Colorado River crisis
Researchers investigating the historic stresses of the American West's water supply have identified a simple solution that could put parts of the Colorado River Basin on a more sustainable path......»»
Authors propose multi-method framework for climate event attribution
At the two most recent meetings of the United Nations Framework Convention on Climate Change, delegates agreed to establish a fund to help developing nations suffering loss and damage due to events linked to climate change, such as floods, heat waves.....»»
Investigating adaptive strategies of high and low nucleic acid prokaryotes
A research team conducted a 73-day large-volume Aquatron macrocosm experiment, utilizing flow cytometry and dilution experiments to thoroughly investigate the temporal changes and influencing factors in the abundance, growth rate, and mortality of hi.....»»
Sound drives "quantum jumps" between electron orbits
Cornell University researchers have demonstrated that acoustic sound waves can be used to control the motion of an electron as it orbits a lattice defect in a diamond, a technique that can potentially improve the sensitivity of quantum sensors and be.....»»
Newly discovered, free-living eukaryote is the first known to have lost its mitochondria
An international team of geneticists and molecular biologists has discovered the first-known, free-living eukaryote to have lost its mitochondria. In their study, published in Nature Communications, the group found the eukaryote while investigating t.....»»
Cleanup hopes for neighbors of Mexico"s "toilet bowl" wastewater dam
On the banks of a wastewater dam in central Mexico, under a dense cloud of mosquitoes, Yury Uribe is finally seeing hope after spending decades in "environmental hell.".....»»
Exoplanets may contain more water than previously thought
We know that the Earth has an iron core surrounded by a mantle of silicate bedrock and water (oceans) on its surface. Science has used this simple planet model until today for investigating exoplanets—planets that orbit another star outside our sol.....»»
Geophysicists find link between seismic waves called PKP precursors and strange anomalies in Earth"s mantle
For the decades since their discovery, seismic signals known as PKP precursors have challenged scientists. Regions of Earth's lower mantle scatter incoming seismic waves, which return to the surface as PKP waves at differing speeds......»»
New AI tool captures how proteins behave in context
A fish on land still waves its fins, but the results are markedly different when that fish is in water. Attributed to renowned computer scientist Alan Kay, the analogy is used to illustrate the power of context in illuminating questions under investi.....»»
Study finds temperature reconstructions during the Common Era are affected by the selection of paleoclimate data
Paleoclimate data, also known as climate proxies, is essential for investigating past climate variability and can help assess the extent of recent climate change......»»
Astronomers find galaxies in denser environments are as much as 25% larger than those in less dense regions
A team of astronomers using a Yale supercomputer have determined for the first time that galaxies in denser environments are as much as 25% larger than their counterparts in less dense regions of the universe......»»
Mediterranean Sea temperatures match 2023 records
The temperatures of the Mediterranean Sea in recent days have reached heat records set last summer, the main Spanish maritime research center told AFP Tuesday, with marine heat waves in some places exceeding 30 degrees Celsius......»»
Study reveals urban trees suffer more from heat waves and drought than their rural counterparts
A recently published study in Ecological Applications details how trees in New York City and Boston are more negatively impacted by heat waves and drought than trees of the same species in nearby rural forests. The finding, made by researchers at the.....»»
A galactic "comet" called Terzan 5 illuminates a 100-year-old puzzle about cosmic rays
When my colleagues and I set to work on a century-old cosmic mystery, we found an unexpected celestial laboratory in Terzan 5, a dense star cluster currently plunging through our galaxy at breakneck speed......»»
How this summer"s heat waves may impact the economy
This sweltering summer has brought record-breaking high temperatures to 63 countries, all but cementing 2024's status as the world's hottest year on record (even though we're barely past the halfway point). Such extreme weather trends are bound to ha.....»»
10 years ago, this disaster movie delivered as much summer fun as Twisters
Twisters is breaking box office records in 2024, but this similar disaster movie about a deadly storm made some waves 10 years ago as a late summer hit......»»
Water delivered to the mantle by aluminum enriched hydrated slabs?
Dense hydrous magnesium silicates (DHMSs) are generally considered as primary water carriers from the shallow lithosphere to the deep mantle transition region (MTR; 410–660 km in depth). Among DHMSs, Superhydrous phase B (hereafter, SuB) holds the.....»»
Using historical radar data to map changes in urban environments
Synthetic aperture radar (SAR) is a type of remote sensing from satellites that uses the reflection of radio waves to relay information about the surface of the earth. This reflection, or backscatter, is responsive to physical properties, such as rou.....»»
Most existing heat wave indices fail to capture heat wave severity, experts report
Even though climate change is bringing more frequent and severe heat waves, there is no standard, global way to measure heat-wave severity, and existing indices have different thresholds for defining dangerous heat-stress conditions......»»
Future Apple Watch band could detect the slightest finger movements and gestures
Apple is investigating how the addition of electrodes to Apple Watch bands could detect the muscle movement and minute electrical activity when a user makes just about any finger gesture.Apple Watch already knows when you're just lazing around and sh.....»»
