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.....»»
A highly performing device for polariton-based coherent microwave emission and amplification
When light strongly interacts with matter, it can produce unique quasi-particles called polaritons, which are half light and half matter. In recent decades, physicists explored the realization of polaritons in optical cavities and their value for the.....»»
Study reveals presence of Hunga Tonga eruption aerosols in Northern Hemisphere stratospheric westerlies
An international team led by researchers from the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences has detected aerosols from the Hunga Tonga eruption in the Northern Hemisphere stratospheric westerlies for the first time......»»
Scientists detect gases from fractured rock

New variable star detected by Chinese astronomers
Using the Nanshan One-meter Wide-field Telescope (NOWT), astronomers from China have performed a photometric survey of the old open cluster NGC 188. In result, they identified many variable stars, one of which was detected for the first time. The fin.....»»
Astronomers find distant gas clouds with leftovers of the first stars
Using ESO's Very Large Telescope (VLT), researchers have found, for the first time, the fingerprints left by the explosion of the first stars in the universe. They detected three distant gas clouds whose chemical composition matches what we expect fr.....»»
Spin.AI partners with Google to reduce the risk of Chrome extensions for SecOps teams
Spin.AI has partnered with Google to integrate its new Chrome Extension Risk Assessment in Chrome Browser Cloud Management. This free tool gives administrators increased visibility into browser extensions detected across the Chrome ecosystem and allo.....»»
Using plasma against toxic PFAS chemicals
Harmful PFAS chemicals can now be detected in many soils and bodies of water. Removing them using conventional filter techniques is costly and almost infeasible. Researchers at the Fraunhofer Institute for Interfacial Engineering and Biotechnology IG.....»»
Double radio relic and odd radio circle discovered with MeerKAT
During observations of the merging galaxy cluster PSZ2 G277.93+12.34 with the MeerKAT radio telescope, an international team of astronomers have serendipitously detected a double radio relic and an odd radio circle. The discovery was detailed in a pa.....»»
JWST"s MIRI instrument is having problems again
Last week, NASA shared a blog post saying they detected a sensor glitch associated with the James Webb Space Telescope's Mid-Infrared Instrument (MIRI). For some reason, the sensor for MIRI's Medium Resolution Spectroscopy (MRS) is receiving less lig.....»»
El Niño–Southern Oscillation correlates well with following-summer cloud-to-ground lightning in China
Large-scale circulation anomalies are a key factor in the transportation of water vapor and changes in climate. For tropical and subtropical regions, an atmospheric circulation field not only determines the characteristics of the weather situation bu.....»»
Ground wide angle camera array detects prompt optical emission of gamma-ray burst
Researchers led by Dr. Xin Liping from the Space-based Multi-band Astronomical Variable Objects Monitor (SVOM) research team, National Astronomical Observatories of the Chinese Academy of Sciences (NAOC), have detected the prompt optical emission and.....»»
PaperCut vulnerabilities leveraged by Clop, LockBit ransomware affiliates
Clop and LockBit ransomware affiliates are behind the recent attacks exploiting vulnerabilities in PaperCut application servers, according to Microsoft and Trend Micro researchers. The detected campaings “Microsoft is attributing the recently r.....»»
A high-throughput AI method for leaf counting
In cereal crops, the number of new leaves each plant produces is used to study the periodic events that constitute the biological life cycle of the crop. The conventional method of determining leaf numbers involves manual counting, which is slow, lab.....»»
Versatile, high-speed, and efficient crystal actuation with photothermally resonated natural vibrations
Every material possesses a unique natural vibration frequency such that when an external periodic force is applied to this material close to this frequency, the vibrations are greatly amplified. In the parlance of physics, this phenomenon is known as.....»»
Lossless light: Revisiting Raman gain and amplification in a silicon photonic platform
Stars emit light that travels through empty space without significant attenuation. The visual signal is essentially lossless until detected. After many years and billions of kilometers, starlight-photons may eventually encounter the earth's atmospher.....»»
G 68-34 is an M-dwarf eclipsing binary, observations find
Using the Tillinghast Reflector Echelle Spectrograph (TRES) and the Transiting Exoplanet Survey Satellite (TESS), astronomers from the Harvard-Smithsonian Center for Astrophysics (CfA) have detected an M-dwarf companion to a nearby M-dwarf star desig.....»»
Fiber optics shed light on solid-state physics phenomena
Researchers from two laboratories at ULB have realized a synthetic dimension for light using a fiber optic ring. This ingenious system simulates the periodic motion of a particle in a crystal in order to study its behavior in the presence of interact.....»»
Cancer-causing chemicals detected in toys and headphones
Cancer-causing chlorinated paraffins are still used in a wide range of everyday products sold in North America, despite their known health harm and being banned in Canada for a decade, according to a new study in Environmental Science: Processes & Im.....»»
