Three new RR Lyrae variable stars discovered
Using the Lulin One-meter Telescope (LOT), astronomers have observed a newly detected candidate ultra-faint dwarf galaxy known as Virgo III. As a result, they discovered three new RR Lyrae variable stars in the vicinity of this galaxy. The finding wa.....»»
Researchers uncover how jelly sea creatures might shape modern robotics
Scientists at the University of Oregon have discovered that colonies of gelatinous sea animals swim through the ocean in giant corkscrew shapes using coordinated jet propulsion, an unusual kind of locomotion that could inspire new designs for efficie.....»»
Ultrasensitive gas detection empowered by synergy of graphene and sub-comb dynamics
Since the inception of microcomb, whose generation relies on Kerr nonlinearity in microresonator, the coherent soliton state has attracted intense research. Although the operation of sub-comb outputs is straightforward, as a noncoherent comb state,.....»»
New candidate genes for human male infertility found by analyzing gorillas" unusual reproductive system
Despite their formidable bodies, male gorillas are lacking in one particular area of their anatomy......»»
Electron vortices in graphene detected for the first time
When an ordinary electrical conductor—such as a metal wire—is connected to a battery, the electrons in the conductor are accelerated by the electric field created by the battery. While moving, electrons frequently collide with impurity atoms or v.....»»
Alternating triangular charge density wave domains observed within a layered superconducting compound
A research team consisting of NIMS and the Tokyo University of Science observed charge density waves (CDWs) within niobium diselenide (NbSe2)—a layered compound—at cryogenic temperatures and discovered that they form alternating triangular domain.....»»
Scientists create black arsenic visible infrared photodetectors
In recent years, the exceptional structure and fascinating electrical and optical properties of two-dimensional (2D) layered crystals have attracted widespread attention. Examples of such crystals include graphene, black phosphorus (BP), and transiti.....»»
Why parrots sometimes adopt—or kill—each other"s babies
Infanticide and adoption in the animal kingdom have long puzzled scientists. While both males and females of many species are known to kill the babies of their rivals to secure sexual or social advantage, other animals have been observed caring for t.....»»
Astronomers observe elusive stellar light surrounding ancient quasars
MIT astronomers have observed the elusive starlight surrounding some of the earliest quasars in the universe. The distant signals, which trace back more than 13 billion years to the universe's infancy, are revealing clues to how the very first black.....»»
Saturday Citations: Parrots on the internet; a map of human wakefulness; the most useless rare-earth element
We field a torrent of science news updates every week and on Saturday morning, we highlight three or four of them based on the observed preferences of a panel of dogs as shown by the Paired-Stimulus Preference Assessment, a standardized evaluation of.....»»
First mother-daughter burial from Roman times in Austria discovered
When a grave was discovered in Wels 20 years ago, the find was thought to be an early medieval double burial of a married couple and a horse due to its unusual features. Only now could the biological gender and family relationships of those buried be.....»»
Weak magnetic field may have supported diversification of life on Earth
An unusual reduction in the strength of Earth's magnetic field between 591 and 565 million years ago coincided with a significant increase in the oxygen levels in the atmosphere and oceans, according to a paper published in Communications Earth & Env.....»»
iPad at war: How the iPad is crucial to the Ukraine war effort
The iPad is being used for an unusual purpose in the Ukraine-Russia conflict — they're helping the Ukraine Air Force use modern weapons on older fighter jets.An iPad in a jet [X/OSINTtechnical]One of the problems of using older vehicles in war is t.....»»
Tidal disruption event ASASSN-19bt experiences unusual radio evolution, observations show
An international team of astronomers has conducted detailed radio and X-ray observations of a tidal disruption event (TDE) designated ASASSN-19bt. Results of the observational campaign, presented April 18 on the pre-print server arXiv, shed more ligh.....»»
Orion"s erupting star system reveals its secrets
An unusual group of stars in the Orion constellation have revealed their secrets. FU Orionis, a double star system, first caught astronomers' attention in 1936 when the central star suddenly became 1,000 times brighter than usual. This behavior, expe.....»»
