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.....»»
Lack of massive black holes in telescope data is caused by bias
Our telescopes have never detected a black hole more massive than 20 times the mass of the sun. Nevertheless, we now know of their existence as dozens of those black holes have recently been "heard" to merge via gravitational wave radiation. A team o.....»»
In a laboratory experiment, researchers simulate alternative hydrocarbon formation through reduction of acetic acid
Hydrocarbons, which are an essential component of crude oil and natural gas, form under pressure and high temperatures in the deep ocean floor. In the Guaymas Basin in the Gulf of California, researchers have detected hydrocarbon gas patterns that co.....»»
Record Number of New Gravitational Waves Offers Game-changing Window Into Universe
Astronomers have detected a record number of gravitational waves, in a discovery they say will shed light on the evolution of the universe, and the life and death of stars. From a report: An international team of scientists have made 35 new observati.....»»
Iconic Periodic Table updated to reflect problems of carbon in our world today

SARS-CoV-2 variant detected in dogs and cats with suspected myocarditis
A new study in the Veterinary Record reveals that pets can be infected with the alpha variant of SARS-CoV-2, which was first detected in southeast England and is commonly known as the UK variant or B.1.1.7. This variant rapidly outcompeted pre-exi.....»»
Increase of Sphagnum mosses over wet aapa mires can be detected from Landsat satellite data
Aapa mire is a northern peatland complex type characterized by wet, sparsely vegetated fens in the central part, while margins are dominated by peat mosses. In recent years, the increase of Sphagnum mosses has been observed in many parts of Finland a.....»»
Researcher argues for existence of companion candidate stars to the eclipsing binary Algol
Dr. Lauri Jetsu from the University of Helsinki has analyzed observations of Algol. He argues that Algol has many companion stars which have not been detected from earlier observations. The results have been published in The Astrophysical Journal......»»
Hungry caterpillars an underappreciated driver of carbon emissions
A study led by the University of Cambridge has found that periodic mass outbreaks of leaf-munching caterpillars can improve the water quality of nearby lakes—but may also increase the lakes' carbon dioxide emissions......»»
Potentially harmful industrial chemicals detected in US fast foods
Chicken nuggets, burritos and other popular items consumers buy from fast food outlets in the United States contain chemicals that are linked to a long list of serious health problems, according to a new study......»»
Breakthrough Listen project releases analysis of previously detected signal
An intriguing candidate signal picked up last year by the Breakthrough Listen project has been subjected to intensive analysis that suggests it is unlikely to originate from the Proxima Centauri system. Instead, it appears to be an artifact of Earth-.....»»
Astronomers Spot First Possible Exoplanet Outside Our Galaxy
A possible Saturn-sized planet identified in the distant Whirlpool Galaxy could be the first exoplanet to be detected outside the Milky Way. From a report: The exoplanet candidate appears to be orbiting an X-ray binary -- made up of a normal star and.....»»
Astronomers may have discovered the first planet outside of our galaxy
Signs of a planet transiting a star outside of the Milky Way galaxy may have been detected for the first time. This intriguing result, using NASA's Chandra X-ray Observatory, opens up a new window to search for exoplanets at greater distances than ev.....»»
Aquatic fungus has already wiped amphibians off the map and now threatens survival of terrestrial frogs
A water-borne fungus that has led to the extinction of several species of amphibians that spend all or part of their life cycle in water is also threatening terrestrial amphibians. In Brazil, researchers supported by FAPESP detected unprecedented mor.....»»
Variability of blazar J1415+1320 investigated by researchers
Astronomers have used the Ooty Radio Telescope (ORT) to probe a blazar known as J1415+1320. Results of the study deliver essential information regarding the variability of this peculiar source. The research was detailed in a paper published October 1.....»»
100s more archaeological sites found on Mexico train route
Mexican experts said Thursday they have detected the ruins of almost 2,500 pre-Hispanic structures and 80 burial sites on just one-sixth of the route of the president's controversial "Maya Train" project on the Yucatan peninsula......»»
FAST, the World"s Largest Radio Telescope, Zooms in on a Furious Cosmic Source

Twisted-angle dependent exciton in heterobilayer of transition metal dichalcogenides
The type-II band structures in vertically stacked transition metal dichalcogenides (TMDs) heterobilayers facilitate the formation of interlayer excitons. The twist-angle and the mismatch in the lattice constants of the monolayers create a periodic mo.....»»
Star"s Strange Path Around Black Hole Proves Einstein Right -- Again
Albert Einstein's theory of general relativity has aced another test. From a report: Following nearly 3 decades of monitoring, researchers have detected a subtle shift in the orbit of the closest known star to the supermassive black hole at the cente.....»»
New giant exoplanet detected with TESS
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new giant alien world. The newfound exoplanet, designated TOI-530b, is only about 17 percent smaller than Jupiter. The finding is reported.....»»
