Quasi-periodic oscillation detected in blazar PKS 0405-385
By analyzing the historical light curve of blazar PKS 0405-385 from NASA's Fermi spacecraft, Chinese astronomers have detected quasi-periodic oscillation from this source. The discovery, presented in a paper published May 5 on arXiv.org, could shed m.....»»
Astronomers discover merging twin quasars
Using the Subaru Telescope in Hawaii, astronomers have detected a pair of merging quasars at a high redshift, as part of the Hyper SuprimeCam (HSC) Subaru Strategic Program (SPP) survey. The serendipitous discovery is reported in the latest issue of.....»»
Avian flu detected in New York City wild birds
A small number of New York City wild birds carry highly pathogenic H5N1 avian influenza, according to a study published in the Journal of Virology,. The work highlights that the interface between animals and humans that may give rise to zoonotic infe.....»»
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.....»»
Webb presents best evidence to date for rocky exoplanet atmosphere
Researchers using NASA/ESA/CSA James Webb Space Telescope may have detected an atmosphere surrounding 55 Cancri e, a rocky exoplanet 41 light-years from Earth. This is the best evidence to date for a rocky planet atmosphere outside our solar system......»»
Cado Security launches solution for forensic investigations in distroless container environments
Cado Security has introduced a solution for conducting forensic investigations in distroless container environments. With Cado Security’s new offering, security teams can investigate the root cause, scope, and impact of malicious activity detected.....»»
Bird flu is bad for poultry and dairy cows: It"s not a dire threat for most of us—yet
Headlines are flying after the Department of Agriculture confirmed that the H5N1 bird flu virus has infected dairy cows around the country. Tests have detected the virus among cattle in nine states, mainly in Texas and New Mexico, and most recently i.....»»
Experts provide facts about avian influenza for dairy producers
While a strain of highly pathogenic avian influenza virus has been detected in dairy cattle in nine states—not including New York state—the commercial milk supply continues to be safe, according to a panel of Cornell, New York state and dairy ind.....»»
The BREAD Collaboration is searching for dark photons using a coaxial dish antenna
Approximately 80% of the matter in the universe is predicted to be so-called "dark matter," which does not emit, reflect, or absorb light and thus cannot be directly detected using conventional experimental techniques......»»
Astronomers" simulations support dark matter theory
Computer simulations by astronomers support the idea that dark matter—matter that no one has yet directly detected but which many physicists think must be there to explain several aspects of the observable universe—exists, according to the resear.....»»
Here"s why we should put a gravitational wave observatory on the moon
Scientists detected the first long-predicted gravitational wave in 2015, and since then, researchers have been hungering for better detectors. But the Earth is warm and seismically noisy, and that will always limit the effectiveness of Earth-based de.....»»
Recently discovered black hole is part of a nearby disrupted star cluster, study finds
European astronomers have investigated a recently detected black hole designated Gaia BH3. In their results, they found that the black hole is associated with a nearby disrupted star cluster known as ED-2. The finding is reported in a paper published.....»»
Pulsating Snake: First millisecond pulsar discovered in the galactic center
Astronomers from the Australia Telescope National Facility (ATNF) report the discovery of a new millisecond pulsar in the "Snake"—a radio filament in the galactic center. It is the first millisecond pulsar detected in the center of our galaxy. The.....»»
H5N1 strain of bird flu found in milk: WHO
The H5N1 bird flu virus strain has been detected in very high concentrations in raw milk from infected animals, the WHO said Friday, though how long the virus can survive in milk is unknown......»»
Astronomers discover the most metal-poor extreme helium star
Using the Southern African Large Telescope (SALT), astronomers have performed high-resolution observations of a recently detected extreme helium star designated EC 19529–4430. It turned out that EC 19529–4430 is the most metal deficient among the.....»»
Beyond equilibrium: Scientists investigate Floquet Fermi liquids
Researchers from Germany and Singapore have studied a non-equilibrium state of Fermi liquids called the Floquet Fermi liquid (FFL), which is formed when Fermi liquids are subjected to a periodic driving force and kept in contact with a fermionic bath.....»»
Hydrogen recombination found to be most plausible explanation for high levels of energy in stellar superflares
Although their primary purpose is to look for exoplanets, observatories like the Kepler Space Telescope and the Transiting Exoplanet Survey Satellite (TESS) have supplied a vast amount of data on stellar flares, detected with high-precision photometr.....»»
Stellar winds of three sun-like stars detected for the first time
An international research team led by a researcher from the University of Vienna has for the first time directly detected stellar winds from three sun-like stars by recording the X-ray emission from their astrospheres, and placed constraints on the m.....»»
Team reports on ultrafast laser state active controlling based on anisotropic quasi-1D material
Tunable ultrafast lasers with adjustable parameters, such as wavelength, intensity, pulse width and laser states are desirable as next-generation intelligent light sources. Due to complex nonlinear effects within the ultrafast system, it is challengi.....»»
New young and warm Jupiter-like exoplanet detected
An international team of astronomers reports the detection of a new young and warm exoplanet orbiting a distant star. The newfound alien world, designated TOI-4862 b (or NGTS-30 b), is similar in size and mass to Jupiter. The finding was published Ap.....»»
Gravitational waves reveal “mystery object” merging with a neutron star
