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.....»»
Very-high energy gamma-ray emission detected from blazar TXS 1515–273
An international team of astronomers has carried out multi-wavelength observations of a blazar known as TXS 1515–273; they detected very-high energy (VHE) gamma-ray emission from this source for the first time. The finding is detailed in a paper pu.....»»
On the hunt for "hierarchical" black holes
Black holes, detected by their gravitational wave signal as they collide with other black holes, could be the product of much earlier parent collisions. Such an event has only been hinted at so far, but scientists at the University of Birmingham in t.....»»
Fermi spots a supernova"s "fizzled" gamma-ray burst
On Aug. 26, 2020, NASA's Fermi Gamma-ray Space Telescope detected a pulse of high-energy radiation that had been racing toward Earth for nearly half the present age of the universe. Lasting only about a second, it turned out to be one for the record.....»»
More and more malware is using Discord"s CDN for abuse
A report by Sophos has exposed the scale and variety of malware using the Discord's CDN: "Sophos products detected and blocked, just in the past two months, nearly 140 times the number of detections over the same period in 2020," said authors Sean Ga.....»»
Image: Hubble views a faraway galaxy through a cosmic lens
The center of this image from the NASA/ESA Hubble Space Telescope is framed by the tell-tale arcs that result from strong gravitational lensing, a striking astronomical phenomenon which can warp, magnify, or even duplicate the appearance of distant g.....»»
Researchers Hid Malware Inside An AI"s "Neurons" And It Worked Scarily Well
According to a new study, malware can be embedded directly into the artificial neurons that make up machine learning models in a way that keeps them from being detected. The neural network would even be able to continue performing its set tasks norma.....»»
InSight mission: Mars unveiled
Using information obtained from around a dozen earthquakes detected on Mars by the Very Broad Band SEIS seismometer, developed in France, the international team of NASA's InSight mission has unveiled the internal structure of Mars. The three papers p.....»»
Astronomers make first clear detection of a moon-forming disc around an exoplanet
Using the Atacama Large Millimetre/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner, astronomers have unambiguously detected the presence of a disk around a planet outside our Solar System for the first time......»»
New X-ray pulsar discovered
Using ART-XC and eROSITA telescopes onboard the Spectrum Roentgen Gamma (SRG) mission, an international team of astronomers has detected a new pulsar. The newly found object, designated SRGA J204318.2+443815, turns out to be a long-period, faint X-ra.....»»
No sign of COVID-19 vaccine in breast milk
Messenger RNA vaccines against COVID-19 were not detected in human milk, according to a small study, providing early evidence that the vaccine mRNA is not transferred to the infant......»»
Chinese astronomers investigate X-ray bursts of SGR J1935+2154
By analyzing the data from NASA's Fermi spacecraft, astronomers from the Hebei Normal University and Nanjing University in China, have investigated X-ray bursting activity of a soft gamma-ray repeater (SGR) known as SGR J1935+2154. Results of the stu.....»»
Spectral-volumetric compressed ultrafast photography simultaneously captures 5D data in a single snapshot
Information-rich optical imaging can provide multidimensional information to enable observation and analysis of a detected target, contributing insights into mysterious and unknown worlds. With its ability to capture dynamic scenes on picosecond—an.....»»
Omitting delays from outbreak models grossly underestimates epidemic severity
For livestock diseases, like foot-and-mouth disease (FMD) and swine flu, rapid culling and carcass disposal are well-established strategies for halting an outbreak and limiting its impact. However, even when infection is quickly detected delays in th.....»»
Scientists use artificial intelligence to detect gravitational waves
When gravitational waves were first detected in 2015 by the advanced Laser Interferometer Gravitational-Wave Observatory (LIGO), they sent a ripple through the scientific community, as they confirmed another of Einstein's theories and marked the birt.....»»
Conservation concern as alien aphid detected on Kangaroo Island
An invasive species of aphid could put some threatened plant species on Kangaroo Island at risk as researchers from the University of South Australia confirm Australia's first sighting of Aphis lugentis on the Island's Dudley Peninsula......»»
Abnormally high alcohol and mystery heat source detected on comet wirtanen
