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.....»»
CO molecular tilting detected by red-shifted TERS
The invention of scanning probe microscopy (SPM) techniques, including scanning tunneling microscopy (STM) and atomic force microscopy (AFM), has led to a paradigm shift in the visualization and understanding of surface structures and related propert.....»»
Humans plunder the periodic table while turning blind eye to the risks of doing so, say researchers
For millions of years, nature has basically been getting by with just a few elements from the periodic table. Carbon, calcium, oxygen, hydrogen, nitrogen, phosphorus, silicon, sulfur, magnesium and potassium are the building blocks of almost all life.....»»

Nuclear reactor experiment rules out one dark matter hope
It was an anomaly detected in the storm of a nuclear reactor so puzzling that physicists hoped it would shine a light on dark matter, one of the universe's greatest mysteries......»»
Existing fiber-optic cable networks could be used to establish a low-cost real-time ocean-Earth observatory
The more than 1.2 million km of fiber-optic cables that crisscross the planet carry the world's phone calls, internet signals and data. But this summer, researchers published the eerie sounds of blue and fin whales detected by a fiber-optic cable on.....»»
Russia will abandon Soyuz on orbit, fly up a new one to bring crew home

Blazar 1ES 1218+304 inspected in detail
An international team of astronomers has performed a comprehensive, multiwavelength study of a blazar known as 1ES 1218+304. Results of the research, presented in a paper published January 3 on the arXiv preprint server, provide more insights into br.....»»
NASA"s retired Compton mission reveals superheavy neutron stars
Astronomers studying archival observations of powerful explosions called short gamma-ray bursts (GRBs) have detected light patterns indicating the brief existence of a superheavy neutron star shortly before it collapsed into a black hole. This fleeti.....»»
Investigating the laser-induced periodic surface structure (LIPSS) of silicon
The electronic and optical devices that we use on a daily basis, such as mobile phones, LEDs and solar cells use transistors and other parts that are consistently getting smaller and more compact. With an ever-growing need for computing power, storag.....»»

Microwave imaging of quasi-periodic pulsations at flare current sheet
Quasi-periodic pulsations (QPPs; also known as quasi-periodic oscillations, i.e., QPOs) are electromagnetic emission phenomena that vary quasi-periodically with time. They appear in celestial transient events with different temporal/spatial scales, s.....»»
Researchers inspect gamma-ray flares of the blazar 3C 279
Using NASA's Fermi spacecraft, Chinese astronomers have investigated the variability and spectral behavior of gamma-ray flares in a distant blazar known as 3C 279. Results of the study, presented in a paper published in the Publications of the Astron.....»»
Chinese astronomers detect over 100 new open clusters
By analyzing the data from ESA's Gaia satellite, astronomers from the Shanghai Astronomical Observatory (SHAO) in China have detected 101 new open clusters in the Milky Way galaxy. The discovery was presented in a paper published December 21 on the a.....»»
TESS detects new "hot Jupiter" exoplanet orbiting a rapidly rotating star
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new "hot Jupiter" exoplanet. The newfound alien world, estimated to be nearly three times as massive as Jupiter, orbits a rapidly rotating.....»»
Russia says it will take no immediate action on damaged Soyuz spacecraft
In reality, the Soyuz is a hardy spacecraft. Enlarge / Three hours after the coolant leak was initially detected Wednesday night, it remained ongoing. (credit: NASA TV) After working through the weekend to better charact.....»»
Study observes Luttinger liquid behavior in a quasi-2D system
Luttinger liquids are usually paramagnetic materials exhibiting non-Fermi liquid behavior, such as molybdenum oxides. These "liquids" and their fascinating properties had so far been only observed in 1D and quasi-1D compounds, such as blue bronze A0......»»
Biggest marsquake was five times larger than previous record-holder
Late on the Earth night of May 4, or Sol 1222 on Mars, the seismometer aboard NASA's InSight Mars Lander detected a quake on the Red Planet, with reverberations lasting many hours. The marsquake was at least five times as large as the next largest qu.....»»
Researchers recreate periodic structure of spine development without biological clocks
