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.....»»
NASA"s InSight detects two sizable quakes on Mars
NASA's InSight lander has detected two strong, clear quakes originating in a location of Mars called Cerberus Fossae—the same place where two strong quakes were seen earlier in the mission. The new quakes have magnitudes of 3.3 and 3.1; the previou.....»»
First interstellar comet may be the most pristine ever found
New observations with the European Southern Observatory's Very Large Telescope (ESO's VLT) indicate that the rogue comet 2I/Borisov, which is only the second and most recently detected interstellar visitor to our Solar System, is one of the most pris.....»»
Scientists Get Closer To Redefining the Length of a Second
Scientists are inching one step closer toward redefining the length of a second. NPR reports: Atomic clocks, which look like a jumble of lasers and wires, work by tapping into the natural oscillation of atoms, with each atom "ticking" at a different.....»»
Scientists discover a new auroral feature on Jupiter
The SwRI-led Ultraviolet Spectrograph (UVS) orbiting Jupiter aboard NASA's Juno spacecraft has detected new faint aurora features, characterized by ring-like emissions, which expand rapidly over time. SwRI scientists determined that charged particles.....»»
Study identifies a new type of diurnal effect for cosmic ray-boosted dark matter
Over the past few decades, astrophysicists and cosmologists have gathered various observations hinting at the existence of dark matter (DM), a type of matter that does not absorb, reflect or emit light, and thus cannot be detected using conventional.....»»
Supervolcano eruption can change the periodic wind system in the tropical stratosphere
The question of what happens in the atmosphere when a supervolcano erupts, has concerned scientists in atmospheric chemistry and meteorology for a while. Now, a research team from UiO, GEOMAR, NCAR, and MPI-M have worked together and come closer to a.....»»
Venus Flytraps Have Magnetic Fields Like the Human Brain
An anonymous reader shares a report from Motherboard (Editor's note: the article was written last week based on findings published in January): [F]or the first time in history, a group of mavericks out of Switzerland have detected a magnetic signal i.....»»
FatFace tells customers to keep its data breach ‘strictly private’
Clothing giant FatFace had a data breach, but doesn’t want you to tell anyone about it. The company sent an email to customers this week disclosing that it first detected a breach on January 17. A hacker made off with the customer’s name,.....»»
Frequent fire too hot to handle for invasive plants
Land managers know one of the best ways to prevent forest fires is to set fires. Periodic controlled or prescribed burns can reduce the amount of flammable materials lying about on a forest floor, so when wildfires do start, they stay small......»»
Astronomers discover four new "hot Jupiters"
An international team of astronomers has detected four new "hot Jupiter" exoplanets as part of the Next Generation Transit Survey (NGTS). The newly found alien worlds are at least 10% larger than Jupiter but less massive than the solar system's bigge.....»»
YouTube Is Testing Automatic Product Detection In Videos
An anonymous reader quotes a report from The Verge: YouTube is always running experiments. One of its latest: testing an automated list of products detected in videos uploaded to the site. As of March 22nd this year, that test is being expanded to "p.....»»
B2 1420+32 is a changing-look blazar, study finds
An international team of astronomers has performed multi-wavelength photometric and spectroscopic observations of a blazar known as B2 1420+32. The observational campaign found that the object exhibits a large scale spectral variability and is the so.....»»
Study outlines testing strategies for safer air travel during the pandemic
Almost 90 percent of infectious travelers could be detected with rapid SARS-CoV-2 tests at the airport, and most imported infections could be prevented with a combination of pre-travel testing and a five-day post-travel quarantine that would only lif.....»»
Method for determining electron beam properties could help future ultraviolet, X-ray synchrotron light sources
The detected intensity from two coherent point-like light sources depends on their relative positions. It is a well-known phenomenon called optical interference. In general, the intensity can range from zero (destructive interference) to some maximum.....»»
Study finds evidence of 55 new chemicals in people
Scientists at UC San Francisco have detected 109 chemicals in a study of pregnant women, including 55 chemicals never before reported in people and 42 "mystery chemicals," whose sources and uses are unknown......»»
Scientists gain insight into recycling processes for nuclear and electronic waste
The Hawaii and Alaska of chemistry, lanthanides and actinides are the elements that are always shown separately from the main block on the periodic table. Although they are split up from the more mainstream elements, they are important metals for app.....»»
About 7 interstellar objects pass through the inner solar system every year, study estimates
In October 19th, 2017, the first interstellar object ever detected flew past Earth on its way out of the solar system. Less than two years later, a second object was detected, an easily identified interstellar comet designated as 2I/Borisov. The appe.....»»
Giant Gravitational Wave Detectors Could Hear Murmurs From Across Universe
sciencehabit writes: Just 5 years ago, physicists opened a new window on the universe when they first detected gravitational waves, ripples in space itself set off when massive black holes or neutron stars spiral together. Even as discoveries pour in.....»»
Not so fast, supernova: Highest-energy cosmic rays detected in star clusters
For decades, researchers assumed the cosmic rays that regularly bombard Earth from the far reaches of the galaxy are born when stars go supernova—when they grow too massive to support the fusion occurring at their cores and explode......»»
Should You Be Wary of All the Free Games?
It's not every day that you can get a free AAA game like GTA 5, but thanks to periodic giveaways, gamers' libraries are bursting with great titles. But we must ask, how this is a valid business strategy?.....»»
