Exploiting dark autoionizing states for enhancing extreme ultraviolet lasers
An international research team led by Professors Tsuneyuki Ozaki and François Légaré at the Institut national de la recherche scientifique (INRS), has developed a unique method to enhance the power of a laser source emitting extreme ultraviolet li.....»»
Study finds fish assess misinformation to avoid overreaction
Fish can adjust their sensitivity to the actions of others—such as fleeing due to a false alarm—to reduce the risk of responding to misinformation, according to a new study. Other animals, including humans, may also have these decision-making mec.....»»
Team successfully tests, validates new method for measuring the precise dimensions and comparability of biomolecules
The precise measurement of biomolecules can play a critical role in improving our understanding of fundamental life processes. In a large-scale comparative study involving 19 laboratories around the globe, a team working with LMU scientists Professor.....»»
Development of advanced lithography technology (I): extension of the existing equipment path
Lithography technology is a mainstream means used by the semiconductor industry to define fine patterns. At present, the most advanced technology is EUV (extreme ultraviolet), and the latest mass production equipment is ASML's TWINSCAN NXE: 3600D. Th.....»»
New machine-learning approach identifies one molecule in a billion selectively, with graphene sensors
Graphene's 2D nature, single molecule sensitivity, low noise, and high carrier concentration have generated a lot of interest in its application in gas sensors. However, due to its inherent non-selectivity, and huge p-doping in atmospheric air, its a.....»»
Study shows promising results in using the sun"s ultraviolet rays to decontaminate water at high altitudes
Research shows that solar water disinfection (SODIS) may be just as effective at decontaminating Escherichia coli (E coli) infected water at high altitudes as it is at low altitudes. The results of a new study appearing in the Wilderness Medical Soci.....»»
Mismatch between conservation status and climate change sensitivity leaves amphibians unprotected
Virginia Tech biological sciences postdoctoral researcher Traci DuBose wants to ensure no frogs or toads land below conservationists' radar......»»
Producing extreme ultraviolet laser pulses efficiently by wakesurfing behind electron beams
A laser pulse surfing in the wake of an electron beam pulse could get upshifted from visible to extreme ultraviolet light, simulations done at the University of Michigan have shown......»»
NASA to launch Israel"s first space telescope
NASA will launch Israel's first space telescope mission, the Ultraviolet Transient Astronomy Satellite (ULTRASAT). ULTRASAT, an ultraviolet observatory with a large field of view, will investigate the secrets of short-duration events in the universe,.....»»
Chiral detection of biomolecules based on reinforcement learning
As one of the basic physical properties, chirality plays an important role in many fields. Especially in biomedical chemistry, the discrimination of enantiomers is a very important research subject. Most biomolecules exhibit weak chirality in the ult.....»»
Genomic study reveals signs of TB adaptation in ancient Andeans
People have inhabited the Andes mountains of South America for more than 9,000 years, adapting to the scarce oxygen available at high altitudes, along with cold temperatures and intense ultraviolet radiation. A new genomic study suggests that Indigen.....»»
In the far-from-diverse publishing industry, sensitivity readers are vital, says researcher
Publishing houses have set the cat among the pigeons. They have introduced "sensitivity readers." Some authors are claiming this amounts to censorship. But what is the truth of this relatively new practice?.....»»
Evolution: Mini-proteins in human organs appeared "from nowhere"
Every biologist knows that small structures can sometimes have a big impact: Millions of signaling molecules, hormones, and other biomolecules are bustling around in our cells and tissues, playing a leading role in many of the key processes occurring.....»»
Researchers reveal new competition mechanism in vacuum ultraviolet photoionization of dichloromethane
A research group led by Prof. Li Haiyang from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) has revealed a new competition mechanism in vacuum ultraviolet photoionization of dichloromethane using a home-buil.....»»
Autofluorescence-free, imaging-guided precision therapy for rheumatoid arthritis
Rheumatoid arthritis (RA), known as "immortal cancer," is a chronic, progressive autoimmune inflammatory disease. The development and application of an RA high-sensitivity theranostics probe can help to accurately monitor the progression and realize.....»»
Study reveals early diagenetic processes of fossil land snail shells from the Chinese Loess Plateau
Terrestrial mollusks are considered as typical "index animals" due to their sensitivity to climate change. They are widely distributed in the semi-arid to arid region of China, including the Chinese Loess Plateau (CLP)......»»
Study: Bright red pigment in red velvet mites protects them against harmful effects of UV radiation and heat
Living on the rugged landscape of rocks and concrete, the red velvet mite Balaustium murorum braves intense sunlight and ultraviolet radiation. These non-parasitic mites feed largely on pollen and emerge during spring from eggs that were laid during.....»»
Deep learning for quantum sensing
