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.....»»
Stealth swimmers: The fish that hide behind other fish to hunt
A new study provides the first experimental evidence that the trumpetfish, Aulostomus maculatus, can conceal itself by swimming closely behind another fish while hunting—and reduce the likelihood of being detected by its prey. The study, involving.....»»
NASA helps spot wine grape disease from skies above California
In a case study, scientists detected the costly infection in cabernet sauvignon grapevines before they showed symptoms visible to the human eye......»»
A solar eruption was detected on Earth, the moon, and even Mars
Scientists recently reported on a solar event that was detectable not only on Earth, but also on the moon and Mars......»»
Two additional exoplanets detected in a nearby planetary system
By conducting radial velocity (RV) follow-up observations of the GJ 367 planetary system with the High Accuracy Radial velocity Planet Searcher (HARPS), an international team of astronomers has detected two additional alien worlds, at least four time.....»»
PFAS detected in blood of horses and dogs too near factory in eastern North Carolina
Debra Stewart walked toward a horse paddock with a bag of carrots in hand. Whisper, a splashed chocolate and white paint horse, met her at the fence......»»
Social media roundup: CSAM on Mastodon; Zuckerberg faces contempt charge; Twitter’s bank plans
An investigation by the Stanford Internet Observatory has found worrying volumes of CSAM on Mastodon. Of particular concern is that the child sexual abuse material included many known examples that should have been automatically detected by digital.....»»
BESSY II: Surface analysis of catalyst particles in aqueous solutions
Green hydrogen can be produced directly in a photoelectrochemical cell, splitting water with solar energy. However, this requires the development of super-efficient photoelectrodes that need to combine many talents at the same time: They must be exce.....»»
A tailor-made magnetic vortex: A closer look at a special kind of quasiparticle
Skyrmions are microscopic magnetic vortices that can form in certain materials. First detected in 2009, they are of interest to researchers because they could be harnessed for new forms of data storage. As theoreticians predicted, there are also so-c.....»»
Does this exoplanet have a "sibling" sharing the same orbit?
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have found the possible "sibling" of a planet orbiting a distant star. The team has detected a cloud of debris that might be sharing this planet's orbit, which they believe co.....»»
Researchers operating Gamma-ray Burst Monitor discover brightest gamma-ray burst ever detected
The University of Alabama in Huntsville (UAH) has announced that three researchers associated with the UAH Center for Space Plasma and Aeronomic Research (CSPAR) have discovered a gamma-ray burst (GRB) approximately 2.4 billion light-years away in th.....»»
Quantitative analysis of cell organelles with artificial intelligence
BESSY II's high-brilliance X-rays can be used to produce microscopic images with spatial resolution down to a few tens of nanometers. Whole cell volumes can be examined without the need for complex sample preparation as in electron microscopy. Under.....»»
New tidal disruption event discovered by Chinese astronomers
Astronomers from the University of Science and Technology of China in Hefei report the discovery of a new faint tidal disruption event (TDE). The newfound TDE, designated AT 2023clx is the faintest and closest optical TDE so far detected. The finding.....»»
Detecting nanoplastics in fractions of a second using modified Raman spectroscopy
Microplastics are tiny, barely visible plastic particles that can harm the environment, for example, if they are eaten by animals. However, it has been difficult to assess the effect of even smaller particles, which can hardly be detected using conve.....»»
We"ve detected a star barely hotter than a pizza oven—the coldest ever found to emit radio waves
We have identified the coldest star ever found to produce radio waves—a brown dwarf too small to be a regular star and too massive to be a planet......»»
Microsoft takes pains to obscure role in 0-days that caused email breach
Critics also decry Microsoft's "pay-to-play" monitoring that detected intrusions. Enlarge (credit: Getty Images | Aurich Lawson) On Friday, Microsoft attempted to explain the cause of a breach that gave hackers working f.....»»
Astronomers discover a luminous nuclear transient
Using NASA's Swift spacecraft, an international team of astronomers has discovered a luminous and slowly-evolving nuclear transient event. The origin of the newly detected transient, designated Swift J221951-484240, is yet to be determined. The findi.....»»
Astronomers use dead stars to measure gravitational waves produced by ancient black holes
An international team of astronomers has detected a faint signal of gravitational waves reverberating through the universe. By using dead stars as a giant network of gravitational wave detectors, the collaboration—called NANOGrav—was able to meas.....»»
Astronomers puzzled by "planet that shouldn"t exist"
The search for planets outside our solar system—exoplanets—is one of the most rapidly growing fields in astronomy. Over the past few decades, more than 5,000 exoplanets have been detected and astronomers now estimate that on average there is at l.....»»
In a First, Scientists See Neutrinos Emitted by the Milky Way
The disk of our galaxy was long thought to produce these ghostly high-energy particles, but they haven’t been detected until now.....»»
First "ghost particle" image of Milky Way galaxy captured by scientists: Neutrinos detected by IceCube
Our Milky Way galaxy is an awe-inspiring feature of the night sky, viewable with the naked eye as a horizon-to-horizon hazy band of stars. Now, for the first time, the IceCube Neutrino Observatory has produced an image of the Milky Way using neutrino.....»»
