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.....»»
"Blob-like" home of farthest-known fast radio burst is collection of seven galaxies, researchers find
In summer 2022, astronomers detected the most powerful fast radio burst (FRB) ever observed. And coming from a location that dates halfway back to the Big Bang, it also was the farthest known FRB spotted to date......»»
Scientists flip around gravitational-wave data analysis: Have LIGO and Virgo detected a merger of dark-matter stars?
Gravitational waves are ripples in the fabric of spacetime that travel at the speed of light. These are produced in some of the most violent events in the universe, such as black-hole mergers, supernovae, or the Big Bang itself. Since their first det.....»»
Pulsations detected from the XZ Ursae Majoris system
Astronomers have conducted a photometric and spectroscopic study of an Algol-type binary, known as XZ Ursae Majoris (or XZ UMa for short). Results of the study, presented in a paper published December 21 on the pre-print server arXiv, indicate that t.....»»
First pulsar detected in globular cluster GLIMPSE-C01
Using the Karl G. Jansky Very Large Array (VLA), astronomers have discovered a millisecond pulsar in the globular cluster GLIMPSE-C01 as part of the VLA Low-band Ionosphere and Transient Experiment (VLITE). This is the first pulsar ever detected in t.....»»
Viruses as important factors driving the diel dynamics of marine bacterioplankton
The diel cycle is one of the most common periodic patterns in marine ecosystems. Previously, the diel rhythm changes of marine bacterioplankton have often been attributed to factors like bacterial light-dependent physiological mechanisms or their int.....»»
3D material found to break down antidepressant that contaminates water bodies worldwide
An study published in the Chemical Engineering Journal describes a strategy to produce a material based on zinc oxide (ZnO) capable of degrading sertraline, an antidepressant that has been detected, like other drugs, in groundwater worldwide and is c.....»»

Mortgage company Mr. Cooper has confirmed that personal information of over 14.6 million customers has been exposed in its October 2023 data breach. The breach “On October 31, 2023, Mr. Cooper detected suspicious activity in certain network sys.....»»
Toxic chemicals found in oil spills and wildfire smoke detected in killer whales
Toxic chemicals produced from oil emissions and wildfire smoke have been found in muscle and liver samples from Southern Resident killer whales and Bigg's killer whales......»»
Second radio relic discovered in the galaxy cluster Abell 2108
Astronomers from India and Taiwan have used the upgraded Giant Metrewave Radio Telescope (uGMRT) to perform radio observations of a galaxy cluster known as Abell 2108. As a result, they detected a second radio relic, which is much larger and differs.....»»
MongoDB corporate systems breached, customer data exposed
Database management company MongoDB has suffered a breach: attackers have gained access to some of its corporate systems and customer data and metadata. The MongoDB breach “We detected suspicious activity on Wednesday (Dec. 13th, 2023) evening.....»»
Ancient stars made extraordinarily heavy elements, researchers find
How heavy can an element be? An international team of researchers has found that ancient stars were capable of producing elements with atomic masses greater than 260, heavier than any element on the periodic table found naturally on Earth. The findin.....»»
Unlocking a climate puzzle: Study reveals hidden physics in quasi-linear temperature-radiation link
Curious about what drives Earth's climate sensitivity? A recent study in Advances in Atmospheric Sciences explores the complex links transforming the relationship between surface temperature and outgoing longwave radiation (OLR) from quartic to quasi.....»»
Diamonds and rust help unveil "impossible" quasi-particles
Researchers have discovered magnetic monopoles—isolated magnetic charges—in a material closely related to rust, a result that could be used to power greener and faster computing technologies......»»
Bashful golden mole detected in South Africa after 87 years
A golden mole that "swims" in sand has resurfaced in South Africa after 87 years in the wilderness when many specialists feared it had become extinct, researchers have said......»»
Study shows unexpected expansion of rare earth element mining activities in Myanmar-China border region
As the demand for rare earth elements increases world-wide, so too do the mining activities associated with rare earth element extraction. Rare earth elements are listed as 15 elements on the periodic table constituting what is known as the lanthanid.....»»
Observations find evolving material, not rings, circling Centaur Chiron
Observations during a stellar occultation detected the presence of evolving material orbiting around Centaur (2060) Chiron, rather than a two-ring system interpretation, according to a paper by Planetary Science Institute Senior Scientist Amanda Sick.....»»
Hackers spent 2+ years looting secrets of chipmaker NXP before being detected
Chipmaker claims breach had no "material adverse effect." Enlarge (credit: Getty Images) A prolific espionage hacking group with ties to China spent over two years looting the corporate network of NXP, the Netherlands-ba.....»»
Vera Rubin Observatory will find binary supermassive black holes: Here"s how
When galaxies merge, we expect them to produce binary black holes (BBHs.) BBHs orbit one another closely, and when they merge, they produce gravitational waves that have been detected by LIGO-Virgo. The upcoming Vera Rubin Observatory should be able.....»»
Dark matter could help solve the final parsec problem of black holes
When galaxies collide, their supermassive black holes enter into a gravitational dance, gradually orbiting each other ever closer until eventually merging. We know they merge because we see the gravitational beasts that result, and we have detected t.....»»
