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.....»»
Researchers use a nanoscale synthetic antiferromagnet to toggle nonlinear spin dynamics
Researchers at the University of California, Riverside, have used a nanoscale synthetic antiferromagnet to control the interaction between magnons—research that could lead to faster and more energy-efficient computers......»»
Bird flu detected in Mali
Mali's agriculture ministry said on Tuesday that it had detected outbreaks of bird flu in the West African state and announced precautionary measures to "contain the disease"......»»
Astronomers detect new chemical signature in an exoplanet"s atmosphere using Subaru Telescope
An international collaboration of astronomers led by a researcher from the Astrobiology Center and Queen's University Belfast has detected a new chemical signature in the atmosphere of an extrasolar planet—i.e., a planet that orbits a star other th.....»»
Complex organic molecules detected in the starless core Lynds 1521E
Using the ARO 12-m telescope, astronomers have investigated a young starless core known as Lynds 1521E (or L1521E). The study resulted in the detection of complex organic molecules in this object. The finding is detailed in a paper April 15 on the ar.....»»
Seismicity on Mars full of surprises, in first continuous year of data
The SEIS seismometer package from the Mars InSight lander has collected its first continuous Martian year of data, revealing some surprises among the more than 500 marsquakes detected so far......»»
Study uncovers human-to-cat transmission of the virus that causes COVID-19
New research provides evidence that people have transmitted SARS-CoV-2, the virus that causes COVID-19, to cats during the pandemic in the UK. The study, which is published in Veterinary Record, detected the virus last year in cats that developed mil.....»»
Scientists find carbon-rich liquid water in ancient meteorite
Water is abundant in the solar system. Even beyond Earth, scientists have detected ice on the moon, in Saturn's rings and in comets, liquid water on Mars and under the surface of Saturn's moon Enceladus, and traces of water vapor in the scorching atm.....»»
Unusual binary system detected with LAMOST
Using the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST), astronomers have discovered an unusual binary system. The newly found binary, designated LAMOST J0140355+392651 (or J0140 for short), consists of a bloated, low-mass proto-.....»»
Holographic metasurface gas sensors for instantaneous visual alarms
Biological and chemical substances can be rapidly detected in real-time for public health and environmental monitoring purposes. In a new report now on Science Advances, Inki Kim and a research team in mechanical engineering, materials science and el.....»»
Modeling collisions between argon nuclei and neutrinos from a supernova
Massive stars end their lives in explosions called core-collapse supernovae. These explosions produce very large numbers of weakly interacting particles called neutrinos. Scientists working on the Deep Underground Neutrino Experiment, hosted by Fermi.....»»
A new super-Earth detected orbiting a red dwarf star
In recent years there has been an exhaustive study of red dwarf stars to find exoplanets in orbit around them. These stars have effective surface temperatures between 2400 and 3700 K (over 2000 degrees cooler than the Sun), and masses between 0.08 an.....»»
Fast radio bursts shown to include lower frequency radio waves than previously detected
Since fast radio bursts (FRBs) were first discovered over a decade ago, scientists have puzzled over what could be generating these intense flashes of radio waves from outside of our galaxy. In a gradual process of elimination, the field of possible.....»»
The American public is responsible for identifying over a quarter of new invasive species
New research by a team at Resources for the Future (RFF) has found that at least 27% of new pests in the United States were initially detected by members of the general public. The study, which was published today in the journal Conservation Science.....»»
Study warns of "oxygen false positives" in search for signs of life on other planets
In the search for life on other planets, the presence of oxygen in a planet's atmosphere is one potential sign of biological activity that might be detected by future telescopes. A new study, however, describes several scenarios in which a lifeless r.....»»
Indian astronomers detect over 200 variable stars
Using the ARIES telescope, astronomers from India have inspected a young open cluster known as NGC 281, searching for new variable stars. As a result of this investigation, they detected 228 new variables. The finding is detailed in a paper published.....»»
Sensitive qubit-based technique to accelerate search for dark matter
Scientists at the Department of Energy's Fermi National Accelerator Laboratory and the University of Chicago have demonstrated a new technique based on quantum technology that will advance the search for dark matter, the invisible stuff that accounts.....»»
First flight of Mars helicopter Ingenuity delayed until next week
We'll have to wait a little longer to see data on the Mars helicopter Ingenuity, due to an issue detected during a test of the rotors......»»
Mars rainbow turns out not to be a rainbow after all
It looks like a rainbow and it arcs like a rainbow, but this image captured on Mars by the Perseverance rover definitely does not show a rainbow......»»
Gamma-ray emission detected from the supernova remnant G272.2-3.2
Using NASA's Fermi Gamma-ray Space Telescope, Chinese astronomers have detected significant GeV gamma-ray emission from a supernova remnant (SNR) known as G272.2-3.2. The finding is detailed in a paper published March 29 on the arXiv pre-print reposi.....»»
New web app ranks spillover risk for newly detected viruses
