Scientists from the Division of Physics at the University of Tsukuba used the quantum effect called 'spin-locking' to significantly enhance the resolution when performing radio-frequency imaging of nitrogen-vacancy defects in diamond. This work may l.....»»
Supercharged heat waves like Washington"s deadliest will strike harder and more often, study says
North America's 2021 heat wave was Washington's deadliest weather-related disaster, claiming over 100 lives in the evergreen state and many others in neighboring regions. Scientists not only suggest that such heat waves will grow more intense and str.....»»
Using gravitational waves to observe thermal effects in binary neutron star mergers
In a study published in The Astrophysical Journal Letters, researchers examined neutron star mergers using THC_M1, a computer code that simulates neutron star mergers and accounts for the bending of spacetimes, due to the strong gravitational field o.....»»
Frostquakes: A new earthquake risk in the north?
A new study has identified a potentially growing natural hazard in the north: frostquakes. With climate change contributing to many observed changes in weather extremes, such as heavy precipitation and cold waves, these seismic events could become mo.....»»
Coral reefs in peril from record-breaking ocean heat
Record breaking marine heat waves will cause devastating mass coral bleaching worldwide in the next few years, according to a University of Queensland coral reef scientist......»»

Radio signals unveil secrets of massive galaxies
Black holes—the cosmic behemoths known for powering some of the brightest radio wave sources in the universe—were the focal point of a study led by Associate Professor Michael Brown, from the School of Physics and Astronomy at Monash University......»»
Collisions change how fast ions surf on plasma waves in fusion experiments and beyond
Just like there are waves in the ocean, waves can also occur in an electrically charged gas called a plasma, made up of electrons and ions. In the ocean, people surf by riding their boards at nearly the same speed as the waves. This matching conditio.....»»
The Universe in a lab: Testing alternate cosmology using a cloud of atoms
We can't experiment with the Universe, but we can make something that works like it. Enlarge / Density waves in a Bose-Einstein condensate. (credit: NASA) In the basement of Kirchhoff-Institut für Physik in Germany, res.....»»
Photonic chip that "fits together like Lego" opens door to semiconductor industry
Researchers at the University of Sydney Nano Institute have invented a compact silicon semiconductor chip that integrates electronics with photonic, or light, components. The new technology significantly expands radio-frequency (RF) bandwidth and the.....»»
Brace for a potentially record-breaking winter after sweltering summer and autumn, say researchers
The scorching heat waves of 2023's summer and autumn shook the world, raising a pertinent question: Will this lead to the warmest winter the globe has ever witnessed?.....»»
An anisotropic density turbulence model from the sun to 1 au derived from radio observations
Density turbulence in the solar corona and solar wind is evident via the properties of solar radio bursts; angular scattering-broadening of extra-solar radio sources observed through the solar atmosphere, and can be measured in-situ in the solar wind.....»»
NASA"s 6-pack of mini-satellites ready for their moment in the sun
Most NASA missions feature one spacecraft or, occasionally, a few. The agency's Sun Radio Interferometer Space Experiment (SunRISE) uses half a dozen. This month, mission members completed the construction of the six identical cereal box-size satelli.....»»
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.....»»
Fubo Radio launches with 10 AI-powered stations for your TV

For its next trick, Gaia could help detect background gravitational waves in the universe
Ripples in a pond can be captivating on a nice sunny day as can ripples in the very fabric of space, although the latter are a little harder to observe. Using the highly tuned Gaia probe, a team of astronomers proposes in a paper posted to arXiv prep.....»»
Vera Rubin Observatory will find binary supermassive black holes: Here"s how
When galaxies merge, we expect them to produce binary black holes (BBHs.) BBHs orbit one another closely, and when they merge, they produce gravitational waves that have been detected by LIGO-Virgo. The upcoming Vera Rubin Observatory should be able.....»»
Study reveals new clues about how whales and dolphins came to use echolocation
A study published in Diversity provides new insight into how toothed whales and dolphins came to navigate the underwater world using sound waves......»»
AI finds formula for how to predict monster waves by using 700 years" worth of data
Long considered myth, freakishly large rogue waves are very real and can split apart ships and even damage oil rigs. Using 700 years' worth of wave data from more than a billion waves, scientists at the University of Copenhagen and University of Vict.....»»
Apple’s plans to bring its own 5G modems to the iPhone have been delayed once again
Apple has been trying to develop its own 5G modems to replace the Qualcomm radio chips currently used in the iPhone. However, even after years of development, the company has struggled to achieve good results with its in-house developed chips. Accord.....»»
Non-native diversity mirrors Earth"s biodiversity: Study highlights potential for future waves of invasive species
