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.....»»
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.....»»
Higher bacterial counts detected in single-serving milks
Cornell University scientists have detected higher bacterial counts in commercial, paperboard single-serving containers two weeks after processing than in milk packaged in larger containers from the same facilities......»»
Study shows that the ATLAS detector can measure the flux of high-energy supernova neutrinos
High-energy neutrinos are extremely rare particles that have so far proved very difficult to detect. Fluxes of these rare particles were first detected by the IceCube Collaboration back in 2013......»»
Security Bite: Self-destructing macOS malware strain disguised as legitimate Mac app
Security researchers at Moonlock, the relatively new cybersecurity wing of MacPaw, have detected a new strain of macOS malware disguised as a legitimate Mac app that can destroy itself in certain conditions. At its worst, it can unknowingly extract c.....»»
Astronomers detect an extremely red supermassive black hole in the early universe growing in the shadows
Analyzing images from the James Webb Space Telescope (JWST), a group of astronomers led by Dr. Lukas Furtak and Prof. Adi Zitrin from Ben-Gurion University of the Negev has detected an extremely red, gravitationally lensed supermassive black hole in.....»»
Scientists find evidence of geothermal activity within icy dwarf planets
A team co-led by Southwest Research Institute found evidence for hydrothermal or metamorphic activity within the icy dwarf planets Eris and Makemake, located in the Kuiper Belt. Methane detected on their surfaces has the tell-tale signs of warm or ev.....»»
Physicists detect elusive "Bragg glass" phase with machine learning tool
Cornell quantum researchers have detected an elusive phase of matter, called the Bragg glass phase, using large volumes of X-ray data and a new machine learning data analysis tool. The discovery settles a long-standing question of whether this almost.....»»
Chinese astronomers find radio pulsar in a supernova remnant
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers from the Nanjing University in China and elsewhere, have detected a radio pulsar in a supernova remnant known as CTB 87. The finding is reported in a paper published.....»»
Ghana: Kumasi city"s unplanned boom is destroying two rivers—sewage, heavy metals and chemical pollution detected
Ghana's urban population has more than tripled in the past three decades, from 4 million to nearly 14 million people. Competition for land in cities has increased among various land uses. These trends have led to encroachment in ecologically sensitiv.....»»
Examining how molecular orbitals determine stability
Carboxylic acid dianions (fumarate, maleate, and succinate) play a role in coordination chemistry and, to some extent, also in the biochemistry of body cells. An HZB team at BESSY II has now analyzed their electronic structures using RIXS in combinat.....»»
Quantum simulation with ultracold fermions unveils pairing pseudogap
A research team has, for the first time, observed and quantitatively characterized the many-body pairing pseudogap in unitary Fermi gases. This achievement, pursued by the ultracold atomic community for nearly two decades, resolves longstanding debat.....»»
Extreme eruption on young sun-like star signals savage environment for developing exoplanets
Astronomers have detected an extreme eruption from a young star that became more than a hundred times brighter in only a few hours. This discovery offers new insight into how young sun-like stars behave early in their lives, and their impact on the d.....»»
Why interstellar objects like ‘Oumuamua and Borisov may hold clues to exoplanets
Two celestial interlopers in Solar System have scientists eagerly anticipating more. Enlarge / The first interstellar interloper detected passing through the Solar System, 1l/‘Oumuamua, came within 24 million miles of the Sun i.....»»
Medicinal drugs pollute the St. Lawrence River, presenting possible risk to aquatic organisms: Study
A new study shows troubling levels of pharmaceutical pollution in the St. Lawrence River and its largest tributaries, especially near and downstream of urban areas. Some of the compounds detected even pose a moderate-to-high risk to aquatic organisms.....»»
