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.....»»
Magnetic superstructures as a promising material for 6G technology
When will 6G be a reality? The race to realize sixth generation (6G) wireless communication systems requires the development of suitable magnetic materials. Scientists from Osaka Metropolitan University and their colleagues have detected an unprecede.....»»
A Chinese Telescope Did Not Find an Alien Signal. The Search Continues.
Earlier this week China's giant Sky Eye telescope detected signals it thought could be from an alien civilizations. But now there's an update from LiveScience: Dan Werthimer, a Search For Extraterrestrial Intelligence (SETI) researcher at the Unive.....»»
‘Alien’ signal seen by Chinese telescope likely due to radio interference
A signal detected by a Chinese telescope and originally reported as possible evidence of extraterrestrial intelligence is almost certainly due to human factors......»»
Apple Watch running metrics: Hands-on with new Workout features in watchOS 9
A wide range of valuable new running features comes with watchOS 9. From heart rate zones and stride length, ground contact time to vertical oscillation, and new features like ghost racing your personal best and creating custom workouts, here’s a.....»»
Chinese Scientists Might Have Detected Signals From Alien Civilizations (Updated)
The team has detected an anomalous transmission using the enormous FAST radio observatory that could be evidence of alien intelligence. The post Chinese Scientists Might Have Detected Signals From Alien Civilizat.....»»
Cosmic "dust" from supernovae hints at how stars are born
New research detected strong polarization from a young supernova remnant. It provided independent and solid evidence that the cosmic dust in the early universe was formed in supernovae. While it's true that supernovae eject and destroy cosmic dust, i.....»»
Research examines X-ray intraday variability of blazar Markarian 421
By analyzing the data from ESA's XMM-Newton satellite, astronomers from the Astronomical Observatory of the Jagiellonian University in Kraków, Poland, and elsewhere, have investigated X-ray intraday variability of a nearby blazar known as Markarian.....»»
Astronomers May Have Detected a "Dark" Free-Floating Black Hole
"If, as astronomers believe, the death of large stars leave behind black holes, there should be hundreds of millions of them scattered throughout the Milky Way galaxy," notes an announcement from the University of California at Berkeley. "The problem.....»»
Italy to kill 1,000 pigs in swine fever outbreak
A thousand pigs will be slaughtered after two cases of swine fever were detected on a farm in Rome's Lazio region, officials said Friday, spurring fears of a blow to the country's pork industry......»»
Astronomers may have detected a "dark" free-floating black hole
If, as astronomers believe, the deaths of large stars leave behind black holes, there should be hundreds of millions of them scattered throughout the Milky Way galaxy. The problem is, isolated black holes are invisible......»»
Methane emissions detected over offshore platform in the Gulf of Mexico
A team of scientists have used satellite data to detect methane plumes from an offshore platform in the Gulf of Mexico. This is the first time that individual methane plumes from offshore platforms have been mapped from space......»»
Topological phase detected in spin chains
In some materials, there are phases between which a transition is not possible because they are protected by a certain form of symmetry. Physicists refer to these as topological phases. One example of this is the Haldane phase, named after the 2016 N.....»»
How moonlight fine-tunes animal reproduction
Animals possess circadian clocks, or 24-hour oscillators, to regulate daily behavior. These typically take their cues from the periodic change of sunlight and darkness. However, many animals are also exposed to moonlight, which reoccurs with ~25h per.....»»
Coherent oscillation between phonons and magnons
Two different waves with the same frequency and wavelengths can be coupled, so that the amplitude alternates periodically between the two to form a phenomenon known as a coherent beating oscillation. The process can be observed often with a coupled p.....»»
Quasi-symmetry in CoSi reveals new type of topological material
Ever since the discovery of the quantum Hall effect (Nobel Prize 1985), symmetry has been the guiding principle in the search for topological materials. Now an international team of researchers from Germany, Switzerland, and the U.S. has introduced a.....»»
Roe’s Fall Will Limit Screening for Fatal Congenital Conditions
Many life-limiting conditions can only be detected 12 weeks into pregnancy—but some US states are planning to set to the abortion limit much earlier......»»
NASA’s InSight Mars Lander’s Days Are Numbered
After the InSight lander studied the strongest marsquake ever detected, scientists gave the space robot a negative prognosis because of its dwindling solar power......»»
With Dusty Solar Panels, InSight’s Days on Mars Are Numbered

European astronomers discover four new brown dwarfs
Astronomers from the Astronomical Observatory of Padova, Italy, and elsewhere have conducted observations of 25 stars as part of the COPAINS Pilot Survey. As a result, they detected four new brown dwarfs that received designations HIP 21152 B, HIP 29.....»»
