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 explore the properties of quasar 1604+159
Chinese astronomers have conducted multi-frequency polarimetric observations of a quasar known as 1604+159. Results of the observational campaign, published August 13 on the pre-print server arXiv, shed more light on the properties of this quasar, in.....»»
A galactic "conspiracy" disproven: Dark matter and stars not interacting as previously thought
A longstanding 'conspiracy' in astronomy—that stars and dark matter are interacting in inexplicable ways—has been overturned by an international team of astronomers, in a paper in Monthly Notices of the Royal Astronomical Society......»»
Observations investigate the connection of a supernova remnant with a nearby H II region
Chinese astronomers have performed multi-wavelength observations of a galactic supernova remnant known as HB9. Results of the observational campaign, published August 9 on the preprint server arXiv, shed more light on the remnant's properties and its.....»»
The bee"s knees: New tests created to find fake honey
Researchers led by Cranfield University have developed new ways to detect sugar syrup adulteration in honey, paving the way for fast and accurate tests to discover fake products......»»
Scientists discover phenomenon impacting Earth"s radiation belts
Two University of Alaska Fairbanks scientists have discovered a new type of "whistler," an electromagnetic wave that carries a substantial amount of lightning energy to the Earth's magnetosphere......»»
Exploring Huntington"s disease: Researchers discover that protein aggregates poke holes in the nuclear membrane
Researchers at Utrecht University in the Netherlands have identified a new way in which the toxic protein aggregates associated with Huntington's disease may damage nerve cells and cause them to die......»»
Researchers discover smarter way to recycle polyurethane
Researchers at Aarhus University have found a better method to recycle polyurethane foam from items like mattresses. This is great news for the budding industry that aims to chemically recover the original components of the material—making their pr.....»»
International astronomy group joins calls for a lunar clock to keep time on the moon
Time moves a tad faster on the moon. Now an international group of astronomers has joined calls to give the moon its own clock so that future space missions can keep track of minutes on the celestial body......»»
Revealing the mysteries within microbial genomes with a new high-throughput approach
A new technique developed at Lawrence Berkeley National Laboratory (Berkeley Lab) will make it much easier for researchers to discover the traits or activities encoded by genes of unknown function in microbes, a key step toward understanding the role.....»»
Researchers discover new way to purify liquid argon for neutrino experiments
Construction workers have finished the excavation of the huge caverns that will house the international Deep Underground Neutrino Experiment. While engineers and technicians are preparing for the installation of the gigantic neutrino detectors into t.....»»
Fish in Greenland consume more jellyfish than previously assumed, researchers discover
For a long time, scientists assumed that jellyfish were a dead-end food source for predatory fish. However, a team from the Alfred Wegener Institute together with the Thünen Institute has now discovered that fish in Greenland waters do indeed feed o.....»»
New analysis of Webb data measures universe expansion rate, finds there may not be a "Hubble tension"
We know many things about our universe, but astronomers are still debating exactly how fast it is expanding. In fact, over the past two decades, two major ways to measure this number—known as the "Hubble constant" —have come up with different ans.....»»
Neutron-star mergers illuminate the mysteries of quark matter
Neutron stars are the remnants of old stars that have run out of nuclear fuel and undergone a supernova explosion and a subsequent gravitational collapse. Although their collisions—or binary mergers—are rare, when they do occur, these violent eve.....»»
New massive eccentric brown dwarf discovered
An international team of astronomers has reported the discovery of a new brown dwarf, which received designation TOI-2490 b. The newfound object is about 74 times more massive than Jupiter and orbits a sun-like star on a highly eccentric orbit. The f.....»»
Astronomers find galaxies in denser environments are as much as 25% larger than those in less dense regions
A team of astronomers using a Yale supercomputer have determined for the first time that galaxies in denser environments are as much as 25% larger than their counterparts in less dense regions of the universe......»»
"Mirror" nuclei help connect nuclear theory and neutron stars
Adding or removing neutrons from an atomic nucleus leads to changes in the size of the nucleus. This in turn causes tiny changes in the energy levels of the atom's electrons, known as isotope shifts. Scientists can use precision measurements of these.....»»
Scientists discover antlions" venom changed to adapt to their ecological niche
In a new study published in Communications Biology, researchers from the Max Planck Institute for Chemical Ecology and the University of Giessen show that the adaptation of antlions to their ecological niche has also changed their venom......»»
Astronomers detect a blazar exhibiting sinusoidal radio variability
An international team of astronomers reports the detection of a blazar with highly significant sinusoidal radio variability using the Owens Valley Radio Observatory (OVRO). The finding was detailed in a research paper published August 5 in the arXiv.....»»
Astronomers ask public to help find newly formed black holes
The Dutch Black Hole Consortium has launched an eight-language version of the BlackHoleFinder app that citizens all over the world can use to help identify newly formed black holes. Previously, the app was only available in Dutch and English......»»
Archaeologists conduct first "space excavation" on ISS and discover surprising quirks of zero-G life
New results from the first archaeological fieldwork conducted in space show the International Space Station is a rich cultural landscape where crew create their own "gravity" to replace Earth's, and adapt module spaces to suit their needs......»»
