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.....»»
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
The so-called "mass gap" might be less empty than physicists previously thought. Enlarge / Artistic rendition of a black hole merging with a neutron star. LIGO/VIRGO/KAGRA detected a merger involving a neutron star and what might.....»»
Astronomers detect potential "glory effect" on a hellish distant world for the first time
Potential signs of the rainbow-like "glory effect" have been detected on a planet outside our solar system. Glory are colorful concentric rings of light that occur only under peculiar conditions......»»
Kerr-enhanced optical spring for next-generation gravitational wave detectors
The detection of gravitational waves stands as one of the most significant achievements in modern physics. In 2017, gravitational waves from the merger of a binary neutron star were detected for the first time which uncovered crucial information abou.....»»
Astronomers find 10 new millisecond pulsars in globular cluster Terzan 5
Using the MeerKAT radio telescope, an international team of astronomers has detected 10 new millisecond pulsars in a Galactic globular cluster known as Terzan 5. The finding, which makes Terzan 5 the most pulsar-rich globular cluster, was reported in.....»»
Cloud Active Defense: Open-source cloud protection
Cloud Active Defense is an open-source solution that integrates decoys into cloud infrastructure. It creates a dilemma for attackers: risk attacking and being detected immediately, or avoid the traps and reduce their effectiveness. Anyone, including.....»»

New cataclysmic variable discovered by astronomers
By analyzing the data from ESA's XMM-Newton and Gaia satellites, astronomers from the Leibniz Institute for Astrophysics Potsdam (AIP) in Germany and elsewhere have detected a new magnetic cataclysmic variable system, most likely of the polar type. T.....»»
Magnetic avalanche triggered by quantum effects: "Barkhausen noise" detected for first time
Iron screws and other so-called ferromagnetic materials are made up of atoms with electrons that act like little magnets. Normally, the orientations of the magnets are aligned within one region of the material but are not aligned from one region to t.....»»
Faintest known star system orbiting the Milky Way discovered
A team of astronomers led by the University of Victoria and Yale University has detected an ancient star system traveling around our galaxy named Ursa Major III / UNIONS 1 (UMa3/U1)—the faintest and lowest-mass Milky Way satellite ever discovered,.....»»
Team reports on the occurrence of antibiotic resistance genes in the western Qinghai Lake basin
Antibiotic resistance genes (ARGs) have been widely detected in water, sediment, gut and even the phycosphere of algae. In strong anthropogenic activity areas, antibiotic resistance caused by ARGs can pose a significant threat to human health. Despit.....»»
Study demonstrates spontaneous self-organization of microdroplets through quasi one-dimensional confinement
Polymer systems composed of multiple components can spontaneously induce emulsion or microdroplets by mechanical mixing, as an intermediate state of macroscopic phase separation. Unfortunately, the size of generated droplets is nonuniform and their s.....»»
Pushing the limit of the periodic table with superheavy elements
Scientists from Massey University in New Zealand, the University of Mainz in Germany, Sorbonne University in France, and the Facility for Rare Isotope Beams (FRIB) discuss the limit of the periodic table and revising the concept of the "island of sta.....»»
Webb finds hints of a third planet at PDS 70
The exoplanet census now stands at 5,599 confirmed discoveries in 4,163 star systems, with another 10,157 candidates awaiting confirmation. So far, the vast majority of these have been detected using indirect methods, including transit photometry (74.....»»
Global warming may intensify the modulation of tropical cyclone genesis by summer intraseasonal oscillation
Global warming, the long-term warming of Earth's overall temperature, has greatly accelerated in the last 100 years due to human factors such as the burning of fossil fuels. Along with this trend, certain atmospheric phenomena have also changed, such.....»»
