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.....»»
Ocean waves propel PFAS back to land, new study finds
A new study by researchers at the Department of Environmental Science, Stockholm University, published in Science Advances, reveals that PFAS re-emit into the air from crashing ocean waves at levels comparable to or greater than other sources, establ.....»»

Rumors suggest Google is looking to offer premium generative AI features just as Apple is allegedly planning an AI App Store for iOS 18.Google could introduce paid premium AI featuresSpeculation and rumors about tech giants come in waves, but if you.....»»
Astronomers find 10 new millisecond pulsars in globular cluster Terzan 5
Using the MeerKAT radio telescope, an international team of astronomers has detected 10 new millisecond pulsars in a Galactic globular cluster known as Terzan 5. The finding, which makes Terzan 5 the most pulsar-rich globular cluster, was reported in.....»»
Spain"s giant hail event worsened by marine heat waves, study finds
Hail is a semi-frequent visitor to winter, and occasionally summer, seasons across the globe and tends to pass by in a short but sharp downpour that can often be overlooked. However, sometimes these meteorological phenomena are hard to ignore. This w.....»»
Study says since 1979 climate change has made heat waves last longer, spike hotter, hurt more people
Climate change is making giant heat waves crawl slower across the globe and they are baking more people for a longer time with higher temperatures over larger areas, a new study finds......»»
Arecibo Observatory telescope outfitted with a wideband cryogenic system to expand its capabilities
Constructed within a natural sinkhole in Puerto Rico, the 305-meter-wide Arecibo Telescope played a part in numerous discoveries, including the first detection of an exoplanet. It was the largest radio telescope in the United States from 1963 until i.....»»
Gravitational waves may have made human life possible
Could it be that human existence depends on gravitational waves? Some key elements in our biological makeup may come from astrophysical events that occur because gravitational waves exist, a research team headed by John R. Ellis of Kings College Lond.....»»
"Shear sound waves" provide the magic for linking ultrasound and magnetic waves
A team led by researchers from the RIKEN Center for Emergent Matter Science in Japan has succeeded in creating a strong coupling between two forms of waves—magnons and phonons—in a thin film. Importantly, they achieved this at room temperature, o.....»»
Study finds decline in the stability of water yield in watersheds
Extreme climatic events such as droughts, heat waves, and cold spells not only modify hydro-meteorological conditions but also alter the underlying characteristics (e.g., wildfires due to droughts changing the vegetation cover). Intense human activit.....»»
Astronomers discover 49 new galaxies in under three hours
An international team of astronomers has discovered 49 new gas-rich galaxies using the MeerKAT radio telescope in South Africa. Their research is published in Monthly Notices of the Royal Astronomical Society......»»
Geomagnetic storm from a solar flare could disrupt radio communications and create a striking aurora
Space weather forecasters have issued a geomagnetic storm watch through Monday, saying an ouburst of plasma from a solar flare could interfere with radio transmissions on Earth. It could also make for great aurora viewing......»»
Tasmania"s tall eucalypt forests will be wiped out by heat waves unless we step in to help them
Tasmania's tall eucalypt forests are globally significant. They accumulate carbon faster than any other natural forest ecosystem in the world......»»
Climate change is speeding up in Antarctica
In recent years, Antarctica has experienced a series of unprecedented heat waves. On 6 February 2020, temperatures of 18.3°C were recorded, the highest ever seen on the continent, beating the previous record of 17.5°C which had only been set a few.....»»
Planet "on the brink", with new heat records likely in 2024: UN
Global temperatures "smashed" heat records last year, as heat waves stalked oceans and glaciers suffered record ice loss, the United Nations said Tuesday—warning 2024 was likely to be even hotter......»»
The cosmic neutrino background would tell us plenty about the universe, says researcher
Readers of Universe Today are probably already familiar with the concept of the cosmic microwave background (CMB). Its serendipitous discovery by a pair of radio astronomers at Bell Labs is the stuff of astronomical legend. Over the past decades, it.....»»
Researchers develop a new type of frequency comb that promises to further boost the accuracy of timekeeping
Chip-based devices known as frequency combs, which measure the frequency of light waves with unparalleled precision, have revolutionized timekeeping, the detection of planets outside of our solar system and high-speed optical communication......»»
Advances and challenges in understanding compound weather and climate extremes
In the context of global warming, many extremes, such as heat waves, heavy precipitation, and droughts, have become increasingly frequent and intense, as expected theoretically. Somewhat unexpectedly, these extremes have also exhibited tightened link.....»»
Astronomers propose a 50-meter submillimeter telescope
Some parts of the universe only reveal important details when observed in radio waves. That explains why we have ALMA, the Atacama Large Millimeter–submillimeter Array, a collection of 7-meter and 12-meter radio telescopes that work together as an.....»»
Gravity waves caused by complex terrain over the Tibetan Plateau can enhance the intensity of spring rainfall
The springtime persistent rainfall is the major rainy period before the onset of summer monsoon in East Asia. For example, it accounts for about 35% of the annual precipitation in South China, which brings plentiful water for agricultural and industr.....»»
AI making waves in marine data collection
Numerous measurement stations around the world provide us with data about air quality, allowing us to enhance it. Although we are increasingly collecting data from marine areas, access to such data is considerably more challenging. Signals are poorly.....»»
