Voyager 1 Detects Plasma "Hum"
Obipale shares a report from Phys.Org: Voyager 1 -- one of two sibling NASA spacecraft launched 44 years ago and now the most distant human-made object in space -- still works and zooms toward infinity. The craft has long since zipped past the edge o.....»»
Endosomal stress, a newly defined organelle stress, induces inflammation via ubiquitin signaling
The endosome is an essential organelle located at the center of membrane traffic and mainly sorts plasma membrane proteins internalized by endocytosis in cooperation with ubiquitination, especially lysine-63-linked polyubiquitin chains (K63 ubiquitin.....»»
Molecular sensor enables water bear hardiness by triggering dormancy, study finds
Tardigrades—hardy, microscopic animals commonly known as "water bears"—use a molecular sensor that detects harmful conditions in their environment, telling them when to go dormant and when to resume normal life. A team led by Derrick R. J. Kollin.....»»
Higher measurement accuracy opens new window to the quantum world
A team at HZB has developed a new measurement method that, for the first time, accurately detects tiny temperature differences in the range of 100 microKelvin in the thermal Hall effect. Previously, these temperature differences could not be measured.....»»
Researchers visualize energetic ion flow in fusion devices
In a burning plasma, maintaining confinement of fusion-produced energetic ions is essential to producing energy. These fusion plasmas host a wide array of electromagnetic waves that can push energetic ions out of the plasma......»»
Skopenow Grid detects the earliest signals of critical risks
Skopenow launched Grid, its new 360-degree situational awareness solution. Grid equips security, intelligence, and investigative teams worldwide with enhanced proactive threat intelligence capabilities, enabling real-time detection of risks to people.....»»
Fermi Gamma-ray Space Telescope detects surprise gamma-ray feature beyond our galaxy
Astronomers analyzing 13 years of data from NASA's Fermi Gamma-ray Space Telescope have found an unexpected and as yet unexplained feature outside of our galaxy......»»
Jupiter has at least three magnetosheath jets, finds Voyager 2 data study
A team of astrophysicists and astronomers from Harbin Institute of Technology, Johns Hopkins University and Peking University has found evidence from Voyager 2 data showing that Jupiter has at least three magnetosheath jets. The study is published in.....»»
Unique permanent coastal observation detects minimal changes
A team of researchers from TU Delft has succeeded in long-term mapping of beach topography to within a few centimeters. The unique dataset provides insights into coastal changes for every hour, for three years. This data is important for dune mainten.....»»
How black silicon, a prized material used in solar cells, gets its dark, rough edge
Researchers at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) have developed a new theoretical model explaining one way to make black silicon, an important material used in solar cells, light sensors, antibacterial surface.....»»
Korean artificial sun, KSTAR, completes divertor upgrades for long pulse operations
The Korean artificial sun, KSTAR, has completed divertor upgrades, allowing it to operate for extended periods sustaining high-temperature plasma over 100 million degrees......»»
Zwicky Transient Facility detects four ultracompact binaries
By investigating dwarf novae identified by the Zwicky Transient Facility (ZTF), astronomers have discovered four binary systems. The objects turned out to be eclipsing accreting ultracompact white dwarf binaries. The finding was reported in a paper p.....»»
How do quark-gluon-plasma fireballs explode into hadrons?
Quark gluon plasma (QGP) is an exciting state of matter that scientists create in a laboratory by colliding two heavy nuclei. These collisions produce a QGP fireball. The fireball expands and cools following the laws of hydrodynamics, which govern ho.....»»
FAST detects three new pulsars in an old globular cluster
Using China's Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers have discovered three new pulsars in an old Galactic globular cluster known as Messier 15. Two of them turned out to be long-period pulsars, while the remaining o.....»»
Computer glitch hampers Voyager 1’s communication system
The nearly 50 year old spacecraft has experienced a glitch which means it is no longer sending science data back to Earth......»»
Engineers working to resolve issue with Voyager 1 computer
Engineers are working to resolve an issue with one of Voyager 1's three onboard computers, called the flight data system (FDS). The spacecraft is receiving and executing commands sent from Earth; however, the FDS is not communicating properly with on.....»»
New plasma instability sheds light on the nature of cosmic rays
Scientists from the Leibniz Institute for Astrophysics Potsdam (AIP) have discovered a new plasma instability that promises to revolutionize our understanding of the origin of cosmic rays and their dynamic impact on galaxies......»»
Not all jets radiate equally in quark-gluon plasma, study finds
Studying nuclear matter under extreme conditions allows scientists to better understand how the universe might have looked right after its creation. Scientists at the Large Hadron Collider achieve the conditions for recreating mini-Big Bangs in the l.....»»
Physicist explains X-rays that shouldn"t exist in "cold" plasma
For about 20 years, Caltech Professor of Applied Physics Paul Bellan and his group have been creating magnetically accelerated jets of plasma, an electrically conducting gas composed of ions and electrons, in a vacuum chamber big enough to hold a per.....»»
Collisions change how fast ions surf on plasma waves in fusion experiments and beyond
Just like there are waves in the ocean, waves can also occur in an electrically charged gas called a plasma, made up of electrons and ions. In the ocean, people surf by riding their boards at nearly the same speed as the waves. This matching conditio.....»»
