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......»»
New Antarctic extremes "virtually certain" as world warms
Extreme events in Antarctica such as ocean heat waves and ice loss will almost certainly become more common and more severe, researchers say......»»
One of 2023"s most extreme heat waves is happening in the middle of winter
Temperatures in parts of Chile and northern Argentina have soared to 10°C–20°C above average over the last few days. Towns in the Andes mountains have reached 38°C or more, while Argentina's capital, Buenos Aires, saw temperatures above 30°C—.....»»
Public interest vs. private homes: Climate change and erosion fuel disputes along Lake Michigan"s shoreline
Steve Coombs' lakefront home used to quake when waves crashed along Ogden Dunes' receding shoreline......»»
Sharks along Nantucket: A researcher has tagged 100-plus sharks there as population rebounds
While much of the shark focus is centered on great whites along Cape Cod this time of year, another shark species has been making waves in recent years off of Nantucket......»»
Big waves becoming more common off California as Earth warms, new research finds
Waves are getting bigger and surf at least 13 feet (about 4 meters) tall is becoming more common off California's coast as the planet warms, according to innovative new research that tracked the increasing height from historical data gathered over th.....»»
Dude, what are those humongous plasma waves in Jupiter’s atmosphere?
Plasma collisions in the outer edges of Jupiter's magnetosphere produce big waves. Enlarge / Lightning crackles behind the dawn edge of Jupiter's atmosphere. (credit: NASA/JPL-Caltech/SwRI/JunoCam) There are waves on Jup.....»»
A Background "Hum" Pervades the Universe. Scientists Are Racing to Find Its Source
Astronomers are now seeking to pinpoint the origins of an exciting new form of gravitational waves that was announced earlier this year.....»»
Scientists identify an alternative system for producing the medical isotope scandium-44
Scandium-44 is a promising medical isotope for positron emission tomography (PET) imaging. PET allows doctors to measure the activity of the cells in the body to help identify cancer, heart disease, and other conditions. Scandium-44 can be produced t.....»»
New radar research overcomes nearly century-old trade-off between wavelength and distance resolution
New interference radar functions employed by a team of researchers from Chapman University and other institutions improve the distance resolution between objects using radar waves. The results may have important ramifications in military, constructio.....»»
California Waves Have Grown a Foot Taller because of Climate Change
The number of extreme wave events—when crests are taller than 13 feet—have doubled along California since the mid-20th century.....»»
California"s winter waves may be increasing under climate change, nearly a century of data show
A new study from UC San Diego Scripps Institution of Oceanography researcher emeritus Peter Bromirski uses nearly a century of data to show that the average heights of winter waves along the California coast have increased as climate change has heate.....»»
How plant biology research could inform COVID-19 treatments
Investigating the building blocks of biology can lead to unexpected outcomes. That's what happened when researchers at the Department of Energy's Oak Ridge National Laboratory were exploring plant genetics. Although their research was focused on impr.....»»
Rippling Waves of Plasma May Cause Massive Stars to "Twinkle"
Scientists have developed a new model to predict how much “gravity waves” could alter a star’s brightness.....»»
Using sound waves to image nanostructures
The potential of an ultrafast form of transmission electron microscopy to measure sound waves in nanostructures has been demonstrated by three RIKEN physicists. This could help realize a high-resolution imaging method that uses ultrahigh-frequency so.....»»
The next Vision Pro could let you see invisible energy
A new patent shows Apple is working on letting the Vision Pro headset visualize invisible energy like Wi-Fi signals and radio waves. Here’s how it could work......»»
Investigating the Ising model with magnetization
Researchers have explored the evolution of systems of interacting spins, as they transition from random to orderly alignments. Through new simulations, they show that this evolution can be investigated by measuring the changing strength of the system.....»»
