An international team of astronomers has employed the James Webb Space Telescope (JWST) to observe a supermassive Galactic open cluster known as Westerlund 1. Results of the observational campaign, presented in a paper published Nov. 20 on the arXiv.....»»
Biochemical alert system makes quick health and environmental monitoring possible
University of Wisconsin–Madison biochemists have developed a new, efficient method that may give first responders, environmental monitoring groups, or even you, the ability to quickly detect harmful and health-relevant substances in our bodies and.....»»
Astronomers discover a "hot Neptune" in a tight orbit
A Neptune-sized planet, TOI-3261 b, makes a scorchingly close orbit around its host star. Only the fourth object of its kind ever found, the planet could reveal clues as to how planets such as these form......»»
Discovering music with Apple Music: from Autoplay to on tour
Apple Music, for me, is about much more than renting access to my favorite songs. The best case scenario for Apple Music, in my experience, is when it guides me to discovering my next favorite album or musician. After School Radio still does it for m.....»»
Observations detect the lowest mass ratio contact binary to date
Astronomers from China and South Korea report the detection of a contact binary system with an extremely low mass ratio of only 0.0356. The newfound system, which received the designation TYC 3801-1529-1, is therefore the lowest mass ratio contact bi.....»»
Magnetically driven vortices may be generating Earth-size concentrations of hydrocarbon haze at Jupiter"s poles
While Jupiter's Great Red Spot has been a constant feature of the planet for centuries, University of California, Berkeley, astronomers have discovered equally large spots at the planet's north and south poles that appear and disappear seemingly at r.....»»

A team of researchers from the Universitat Politècnica de València (UPV), belonging to the LARS-IIAMA group, has used satellite technology to detect methane emissions in the palm oil industry in Indonesia, Malaysia and Colombia. Their study, publis.....»»
Astronomers measure cosmic electrons at the highest energies to date
Five telescopes of the H.E.S.S.-collaboration in Namibia are used to study cosmic radiation, especially gamma radiation. With data from 10 years of observations, researchers have now been able to detect cosmic electrons and positrons with an unpreced.....»»
Researchers pioneer method to detect dehydration in plants
Have you ever wondered if your plants were dry and dehydrated, or if you're not watering them enough? Farmers and green-fingered enthusiasts alike may soon have a way to find this out in real time. Over the past decade, researchers have been working.....»»
Unusual supernova observations grant astronomers a peek into the cosmic past
An international team of researchers has made new observations of an unusual supernova, finding the most metal-poor stellar explosion ever observed......»»
Cyanobacterial circadian clock uses an AM radio-like mechanism to control cellular processes
Cyanobacteria, an ancient lineage of bacteria that perform photosynthesis, have been found to regulate their genes using the same physics principle used in AM radio transmission......»»
Astronomers discover a rare group of dwarf galaxies
Astronomers from the Yonsei University in Seoul, South Korea and elsewhere have discovered a rare isolated group of five star-forming dwarf galaxies in the local universe. The finding was reported in a research paper published November 19 in The Astr.....»»
WEAVE spectrograph uncovers dual nature of galaxy shock
Using the set of first-light observations from the new William Herschel Telescope Enhanced Area Velocity Explorer (WEAVE) wide-field spectrograph, a team of more than 50 astronomers, led by Dr. Marina Arnaudova at the University of Hertfordshire, has.....»»
Saturday Citations: Sweaty, remarkable humans; ocean level rise projections; closeup of a star in another galaxy
Since we last spoke, researchers at the University of Birmingham have defined the precise shape of a single photon (spoiler: roundish). Economists worry that Trump's grandiose deportation plans could lead to a recession. And astronomers report that t.....»»
Hubble finds sizzling details about young star FU Orionis
In 1936, astronomers saw a puzzling event in the constellation Orion: the young star FU Orionis (FU Ori) became a hundred times brighter in a matter of months. At its peak, FU Ori was intrinsically 100 times brighter than our sun. Unlike an exploding.....»»
Broadcast police communications may pose privacy risks, especially to Black men
Police radio transmissions contain personally identifiable information that could pose privacy risks for members of the public, especially Black males, according to a new study by researchers at Penn State and the University of Chicago......»»
Astronomers snap first up-close image of a star outside our galaxy
Astronomers have taken a detailed image of a star outside of the Milky Way for the first time......»»
Child safety org flags new CSAM with AI trained on real child sex abuse images
AI will make it harder to spread CSAM online, child safety org says. For years, hashing technology has made it possible for platforms to automatically detect known child sexual ab.....»»
A nearby supernova could end the search for dark matter
The search for the universe's dark matter could end tomorrow—given a nearby supernova and a little luck. The nature of dark matter has eluded astronomers for 90 years, since the realization that 85% of the matter in the universe is not visible thro.....»»
Are fast radio bursts caused by interstellar objects crashing into neutron stars?
Every now and then, astronomers will detect an odd kind of radio signal. So powerful it can outshine a galaxy, but lasting only milliseconds. They are known as fast radio bursts (FRBs). When they were first discovered a couple of decades ago, we had.....»»
