Over a thousand cosmic explosions detected in 47 days
An international research team led by Prof. Li Di and Dr. Wang Pei from National Astronomical Observatories of Chinese Academy of Sciences (NAOC) caught an extreme episode of cosmic explosions from Fast Radio Burst (FRB) 121102, using the Five-hundre.....»»
We found a mysterious flashing radio signal from near the centre of the galaxy
In early 2020, we detected an unusual radio signal coming from somewhere near the center of our galaxy. The signal blinked on and off, growing 100 times brighter and dimmer over time......»»
Quantum phase transition detected on a global scale deep inside the Earth
The interior of the Earth is a mystery, especially at greater depths (> 660 km). Researchers only have seismic tomographic images of this region and, to interpret them, they need to calculate seismic (acoustic) velocities in minerals at high pressure.....»»
Researchers propose novel permanent magnet design methods for quasi-axisymmetric stellarator
A new permanent magnet design of quasi-axisymmetric stellarator was made by researchers led by Prof. Xu Guosheng from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences......»»
Microsoft: Russia Behind 58% of Detected State-backed Hacks
Russia accounted for most state-sponsored hacking detected by Microsoft over the past year, with a 58% share, mostly targeting government agencies and think tanks in the United States, followed by Ukraine, Britain and European NATO members, the compa.....»»
Periodic variability of quasar QSO B1312+7837 identified by researchers
Using the Rozhen National Astronomical Observatory (NAO) in Bulgaria, astronomers have performed long-term monitoring of the quasar QSO B1312+7837 and have detected a periodic variability of this source. The finding is reported in a paper published S.....»»
REvil alone accounts for a significant portion of Q2 2021 ransomware attacks
Computer security company McAfee recently published its Advanced Threat Research Report for October 2021. One of the subjects it covers is statistics on ransomware attacks the company detected in the second quarter of this year. In terms of the numbe.....»»
Researchers observe interference effect between Floquet quasi-particles using strontium optical lattice clock
Based on the strontium optical lattice clock platform, a research team led by Prof. Chang Hong from the National Time Service Center of the Chinese Academy of Sciences, together with Zhang Xuefeng from Chongqing University observed the interference e.....»»
New warm mini-Neptune exoplanet detected by TESS
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new warm mini-Neptune alien world transiting a bright M-dwarf star. The newly found exoplanet, designated TOI-1201b, is estimated to be abo.....»»
Physicists demystify magic: bona fide topological Mott insulator discovered in twisted bilayer graphene model
Imagine stacking two sheets of graphene—the 2D form of graphite, or the pencil at your hand—in which the carbon atoms form a hexagonal lattice and twist the top sheet out of alignment with the sheet below, yielding a periodic arrangement of atoms.....»»
InSight lander measures one of its biggest-ever marsquakes shaking the planet
This month, the InSight lander detected one of its biggest ever marsquakes, which hit a magnitude of 4.2 and lasted for nearly ninety minutes on September 18......»»

Quasi-particles with tunable interactions
The laws of quantum mechanics allow for the existence of 'quasi-particles': excitations in materials that behave exactly like ordinary particles. A major advantage of quasi-particles over ordinary particles is that their properties can be engineered......»»
Cloud-spotting on a distant exoplanet
An international team of astronomers has not only detected clouds on the distant exoplanet WASP-127b, but also measured their altitude with unprecedented precision. A presentation by Dr. Romain Allart at the Europlanet Science Congress (EPSC) 2021 sh.....»»
NASA"s InSight finds three big marsquakes, thanks to solar-panel dusting
On Sept. 18, NASA's InSight lander celebrated its 1,000th Martian day, or sol, by measuring one of the biggest, longest-lasting marsquakes the mission has ever detected. The temblor is estimated to be about a magnitude 4.2 and shook for nearly an hou.....»»
Infants have more microplastics in their feces than adults, study finds
Microplastics—tiny plastic pieces less than 5 mm in size—are everywhere, from indoor dust to food to bottled water. So it's not surprising that scientists have detected these particles in the feces of people and pets. Now, in a small pilot study,.....»»
"Black widow" pulsar detected in globular cluster NGC 6712
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers have discovered a new pulsar in the globular cluster NGC 6712. The newly found object is a so-called "black widow," and the first radio pulsar identified so far in th.....»»
Nation-state espionage group breaches Alaska Department of Health
Fallout continues from an advanced persistent threat first detected in May 2021. Enlarge / If Alaska's native Ursus arctos population could be enlisted for cyber defense patrols, attackers might need paws for reflection before committing a crimi.....»»
Have we detected dark energy? Scientists say it"s a possibility
A new study, led by researchers at the University of Cambridge and reported in the journal Physical Review D, suggests that some unexplained results from the XENON1T experiment in Italy may have been caused by dark energy, and not the dark matter the.....»»
