Fermi Arcs in an antiferromagnet detected at BESSY II
An international cooperation has analyzed samples of NdBi crystals, which display interesting magnetic properties. In their experiments including measurements at BESSY II, they could find evidence for so called Fermi arcs in the antiferromagnetic sta.....»»
Early warning signals could help monitor disease outbreaks
New research suggests early warning signals (EWSs) could help in the monitoring of disease outbreaks, such as COVID-19. The study found warnings could be detected weeks earlier than any rapid increase in cases. The findings could help governments and.....»»
New air pollution detection model promises more accurate picture
Air pollutants that have previously escaped monitoring can now be detected through a new method developed at the University of East Anglia (UEA), promising a more complete picture for people and policy development......»»
The shortest-period gas-giant exoplanet discovered with TESS
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international group of astronomers has detected a new, ultra-hot gas giant exoplanet with an extremely short orbital period. The newfound alien world, designated TOI-2109b is about five ti.....»»
Radio emission detected from the Vela X-1 bow shock
An international team of astronomers has conducted radio observations of a bow shock in the X-ray binary Vela X-1 using MeerKAT telescope. The observational campaign resulted in the detection of radio emission from this source. The finding is detaile.....»»
Could we really deflect an asteroid heading for Earth? An expert explains NASA"s latest DART mission
A NASA spacecraft the size of a golf cart has been directed to smash into an asteroid, with the intention of knocking it slightly off course. The test aims to demonstrate our technological readiness in case an actual asteroid threat is detected in th.....»»
A new way to generate electricity from waste heat: Using an antiferromagnet for solid devices
Forcing electrons to flow perpendicularly to a heat flow requires an external magnetic field—this is known as the Nernst effect. In a permanently magnetized material (a ferromagnet), an anomalous Nernst effect (ANE) exists that can generate electri.....»»
If alien probes are already in the solar system, maybe we could detect them calling home
It's been 70 years since physicist Enrico Fermi asked his famous question: "Where is everybody?" And yet, the tyranny of the Fermi Paradox is still with us and will continue to be until definitive evidence of extraterrestrial intelligence (ETI) is fo.....»»
Energizer atoms: Physicists find new way to keep atoms excited
JILA researchers have tricked nature by tuning a dense quantum gas of atoms to make a congested "Fermi sea," thus keeping atoms in a high-energy state, or excited, for about 10% longer than usual by delaying their normal return to the lowest-energy s.....»»
German farm to cull 4,000 pigs after swine fever detected
A pig farm in northern Germany began culling all of its 4,000 animals Wednesday after a case of African swine fever was confirmed there......»»
Lawsuit Over Subway Tuna Now Says Chicken, Pork, Cattle DNA Were Detected
A new version of a lawsuit accusing Subway of deceiving the public about its tuna products said lab testing shows they contain animal proteins such as chicken, pork and cattle, and not the advertised "100% tuna." From a report: Karen Dhanowa and Nili.....»»
Astronomers discover a sub-Neptune exoplanet orbiting nearby star
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a sub-Neptune exoplanet orbiting a nearby M dwarf star. The newly found alien world, designated TOI-2257b is about two times larger than the.....»»
Theranos tests detected prostate-cancer marker in prostateless women
Holmes struggled to explain why Theranos test found male biomarker in women. Enlarge / Former Theranos founder and CEO Elizabeth Holmes goes through security after arriving for court at the Robert F. Peckham Federal Building on Septemb.....»»
The role of animal pheromones in regulating fat burning and longevity
Pheromones are potent molecules that mediate communications between animals and even between humans. Usually, a sender animal synthesizes and excretes pheromones to the environment; pheromones are detected by a receiver animal and elicit dramatic cha.....»»
Using machine learning to derive black hole motion from gravitational waves
The announcement that the Laser Interferometer Gravitational-wave Observatory (LIGO) had detected gravitational waves during the merger of two black holes sent ripples throughout the scientific community in 2016. The earthshaking news not only confir.....»»
Satellites detect large methane emissions from Madrid landfills
High-resolution satellites have detected substantial quantities of methane leaking from adjacent landfill sites close to the center of Madrid, Spain. Using data from the Copernicus Sentinel-5P mission combined with GHGSat's high-resolution commercial.....»»
Data from the Fermi Large Area Telescope suggests there is a particle accelerator in the galactic center
A team of researchers at the Chinese Academy of Sciences has found evidence of a powerful particle accelerator in the galactic center. In their paper published in the journal Nature Communications, the group describes their analysis of data obtained.....»»
Lack of massive black holes in telescope data is caused by bias
Our telescopes have never detected a black hole more massive than 20 times the mass of the sun. Nevertheless, we now know of their existence as dozens of those black holes have recently been "heard" to merge via gravitational wave radiation. A team o.....»»
In a laboratory experiment, researchers simulate alternative hydrocarbon formation through reduction of acetic acid
Hydrocarbons, which are an essential component of crude oil and natural gas, form under pressure and high temperatures in the deep ocean floor. In the Guaymas Basin in the Gulf of California, researchers have detected hydrocarbon gas patterns that co.....»»
Record Number of New Gravitational Waves Offers Game-changing Window Into Universe
Astronomers have detected a record number of gravitational waves, in a discovery they say will shed light on the evolution of the universe, and the life and death of stars. From a report: An international team of scientists have made 35 new observati.....»»
Discovery of segmented Fermi surface induced by Cooper pair momentum on a hybrid material platform
