Seeing with radio waves
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.....»»
Space oddity: Uncovering the origin of the universe"s rare radio circles
It's not every day astronomers say, "What is that?" After all, most observed astronomical phenomena are known: stars, planets, black holes and galaxies. But in 2019 the newly completed ASKAP (Australian Square Kilometer Array Pathfinder) telescope pi.....»»
Scientists flip around gravitational-wave data analysis: Have LIGO and Virgo detected a merger of dark-matter stars?
Gravitational waves are ripples in the fabric of spacetime that travel at the speed of light. These are produced in some of the most violent events in the universe, such as black-hole mergers, supernovae, or the Big Bang itself. Since their first det.....»»
Surf"s up: Big waves pound US West Coast
Huge surf was battering the US West Coast on Friday, with forecasters warning of more danger ahead after a rogue wave swept pedestrians off their feet and swamped a hotel......»»
First release of the largest extragalactic HI catalog
The FAST All Sky HI survey (FASHI) was designed to cover the entire sky observable by the Five-hundred-meter Aperture Spherical radio Telescope (FAST), spanning approximately 22,000 square degrees of declination between -14 deg and +66 deg, and in th.....»»
Harnessing all-dielectric metamaterials to manipulate the polarization state of light
Polarization is one of the fundamental characteristics of electromagnetic waves. It can convey valuable vector information in sensitive measurements and signal transmission, which is a promising technology for various fields such as environmental mon.....»»
Marine heat waves: Why the East Sea experienced extreme conditions in 2021
Extreme environmental events are becoming an ever more pressing concern with the continued stresses of climate change, both on land and in the marine realm. While terrestrial heat waves tend to occur over a few days, those in the oceans often have lo.....»»
Constraining the dynamics of rotating black holes via the gauge symmetry principle
In 2015, the LIGO/Virgo experiment, a large-scale research effort based at two observatories in the United States, led to the first direct observation of gravitational waves. This important milestone has since prompted physicists worldwide to devise.....»»
FAST detects three new pulsars in an old globular cluster
Using China's Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers have discovered three new pulsars in an old Galactic globular cluster known as Messier 15. Two of them turned out to be long-period pulsars, while the remaining o.....»»
Volkswagen, Audi, Porsche and Scout to adopt Tesla EV charging standard
Starting in 2025, Volkswagen, Audi and Porsche electric vehicles will be equipped with the North American Charging Standard port. The three brands have waves of EVs coming......»»
History and contents of the universe can be determined using radio telescopes on the moon, researchers say
A study from Tel Aviv University has predicted for the first time the groundbreaking results that can be obtained from a lunar-based detection of radio waves. The study's findings show that the measured radio signals can be used for a novel test of t.....»»
Second radio relic discovered in the galaxy cluster Abell 2108
Astronomers from India and Taiwan have used the upgraded Giant Metrewave Radio Telescope (uGMRT) to perform radio observations of a galaxy cluster known as Abell 2108. As a result, they detected a second radio relic, which is much larger and differs.....»»
Some coral species might be more resilient to climate change than previously thought
Some coral species can be resilient to marine heat waves by "remembering" how they lived through previous ones, research by Oregon State University scientists suggests......»»
Research reveals regions in US where heat adaptation and mitigation efforts can most benefit future populations
Extreme heat waves, once considered rare, are now frequent and severe in cities due to climate change. Phoenix faced such a brutal heat wave in July of 2023 when it endured 31 consecutive days of high temperatures of at least 110° F. The severity of.....»»
Custom software speeds up, stabilizes high-profile ocean model
On the beach, ocean waves provide soothing white noise. But in scientific laboratories, they play a key role in weather forecasting and climate research. Along with the atmosphere, the ocean is typically one of the largest and most computationally de.....»»
Breakthrough Listen scans entire galaxies for signals from extremely advanced civilizations
In 1960, Dr. Frank Drake led the first Search for Extraterrestrial Intelligence (SETI) experiment at the National Radio Astronomy Observatory in Green Bank, West Virginia. In the more than sixty years that have since passed, astronomers have conducte.....»»
The new era of SiriusXM starts today with a revamped app
SiriusXM is blurring the lines between streaming and satellite radio, starting with the launch of a revamped app and web experience......»»
A strategy to realize the efficient resonant absorption of guided water waves
The absorption of water waves is the process through which water waves lose their energy, thus reducing their impact on shores or other solid structures surrounding them. Enabling this absorption process in real-world settings could help protect coas.....»»
Unlocking the secrets of fast radio bursts: More pieces to the puzzle of mysterious space signals
A team of SETI Institute scientists has unveiled new insights into a cosmic mystery known as Fast Radio Bursts (FRBs). The discovery and detailed observation of the repeating FRB 20220912A, made at the SETI Institute's refurbished Allen Telescope Arr.....»»
Understanding the key to predicting heat events in Central Europe
