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.....»»
Russia says it will take no immediate action on damaged Soyuz spacecraft
In reality, the Soyuz is a hardy spacecraft. Enlarge / Three hours after the coolant leak was initially detected Wednesday night, it remained ongoing. (credit: NASA TV) After working through the weekend to better charact.....»»
Study observes Luttinger liquid behavior in a quasi-2D system
Luttinger liquids are usually paramagnetic materials exhibiting non-Fermi liquid behavior, such as molybdenum oxides. These "liquids" and their fascinating properties had so far been only observed in 1D and quasi-1D compounds, such as blue bronze A0......»»
The discovery of interfacial ferromagnetism in 2D antiferromagnet heterostructures
Van der Waals (vdW) magnets and their heterostructures have emerged as new platforms to explore exotic magnetic orders and quantum phenomena......»»
Biggest marsquake was five times larger than previous record-holder
Late on the Earth night of May 4, or Sol 1222 on Mars, the seismometer aboard NASA's InSight Mars Lander detected a quake on the Red Planet, with reverberations lasting many hours. The marsquake was at least five times as large as the next largest qu.....»»
Maybe we don"t see aliens because they"re waiting to hear a signal from us first
We've had a long-running series here at UT on potential solutions Fermi paradox—why aren't we able to detect any alien life out there in the Universe? But more possible solutions are being developed all the time. Now, another paper adds some additi.....»»
Black hole "carnivals" may produce the signals seen by gravitational-wave detectors
Since 2015, the LIGO-Virgo-KAGRA Collaboration have detected about 85 pairs of black holes crashing into each other. We now know that Einstein was right: gravitational waves are generated by these systems as they inspiral around each other, distortin.....»»
If there is phosphine on Venus, there isn"t much
In the absence of direct observations of extraterrestrial life, scientists often focus on searching for biosignatures, chemical by-products of life, that can be detected with remote sensing. Although Mars has received the most attention in this regar.....»»
More than 52 million birds in the US have been affected by an outbreak of avian influenza
A form of highly pathogenic avian influenza (HPAI) has been causing widespread disruption and illness in birds since first being detected roughly a year ago. Last March, a bald eagle found dead in Pennsylvania's Chester County became the first confir.....»»
LastPass, GoTo announce security incident
LastPass and its affiliate GoTo (formerly LogMeIn) have announced that they suffered a security incident and, in LastPass’ case, a possible data breach. “Based on the investigation to date, we have detected unusual activity within our dev.....»»
Mysteriously bright flash is a black hole jet pointing straight toward Earth, astronomers say
Earlier this year, astronomers were keeping tabs on data from the Zwicky Transient Facility, an all-sky survey based at the Palomar Observatory in California, when they detected an extraordinary flash in a part of the sky where no such light had been.....»»
Most distant detection of a black hole swallowing a star
Earlier this year, the European Southern Observatory's Very Large Telescope (ESO's VLT) was alerted after an unusual source of visible light had been detected by a survey telescope. The VLT, together with other telescopes, was swiftly repositioned to.....»»
Two new young open clusters discovered
By analyzing the data from ESA's Gaia satellite, astronomers have detected two new young open clusters. The newfound clusters, designated Casado 82 and Casado-Hendy 1, are located in a nearby primordial group of open clusters. The finding is reported.....»»
An ultra-short-period exoplanet discovered with TESS
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new ultra-short-period exoplanet. The newfound alien world, designated HD 20329 b, orbits its host star in slightly less than one day. The.....»»
Astronomers detect new Jupiter-like exoplanet
Using radial velocity measurements, astronomers from Japan and China have detected a new exoplanet orbiting a G-type giant star. The newfound alien world is similar in mass to Jupiter but much hotter than the solar system's biggest planet. The discov.....»»
Bird flu detected in southeast Alaska black bear cub
A black bear cub in southeast Alaska was euthanized after it became ill with avian influenza, the Alaska Department of Fish and Game said......»»
Scientists use carbon to detect a new nitrogen source in the open ocean
Lawrence Livermore National Laboratory (LLNL) and UC Santa Cruz scientists have detected a previously hypothesized class of nitrogen fixation in the surface ocean......»»
Tick-borne pathogens increasingly widespread in Central Canada
Tick-borne pathogens, known for causing illnesses such as Lyme disease, are on the rise in Central Canada—presenting new risks in areas where they were never previously detected......»»
Changing-look events observed in the galaxy NGC 5273
Astronomers have analyzed new and archival multiwavelength observations of the active galaxy NGC 5273. As a result, they detected so-called "changing-look" events in the active galactic nucleus of this galaxy. The finding is reported in a paper publi.....»»
Cesium detected in the atmosphere of a hot white dwarf
By analyzing the data from the Far Ultraviolet Spectroscopic Explorer (FUSE) telescope, an international team of astronomers has discovered cesium in the atmosphere of a hot white dwarf known as HD 149499B. The finding, reported November 3 on the arX.....»»
Black holes don"t always power gamma-ray bursts, new research shows
Gamma-ray bursts (GRBs) have been detected by satellites orbiting Earth as luminous flashes of the most energetic gamma-ray radiation lasting milliseconds to hundreds of seconds. These catastrophic blasts occur in distant galaxies, billions of light.....»»
