Ionic crystal generates molecular ions upon positron irradiation
The positron, the antiparticle of the electron, has the same mass and charge as that of an electron but with the sign flipped for the charge. It is an attractive particle for scientists because the use of positrons has led to important insights and d.....»»
Discovery of magnetic liquid crystal: First direct observation of spin quadrupole moments in a spin-nematic phase
Liquid crystal is a state of matter that exhibits properties of both liquid and solid. It can flow like a liquid, while its constituent molecules are aligned as in a solid. Liquid crystal is widely used nowadays, for example, as a core element of LCD.....»»
Guide: Application security posture management deep dive
Distinguishing real, business-critical application risks is more challenging than ever. A siloed, ad hoc approach to AppSec generates noisy false positives that overwhelm under-resourced security teams. You need a multidimensional approach that lever.....»»
Researchers identify molecular basis for morphological diversity of amniote skull
A research group led by Associate Professor Masayoshi Tokita explored the molecular basis generating the diversity of amniote skull morphology, using embryos of several amniote species as materials......»»
Permselectivity reveals a cool side of nanopores
Researchers from Osaka University investigated the thermal energy changes across nanopores that allow the selective flow of ions. Switching off the flow of ions in one direction led to a cooling effect. The findings have applications in nanofluidic d.....»»
Molecular fossils study sheds light on feeding strategy shift in ancient life
Paleontologists are getting a glimpse at life over a billion years in the past based on chemical traces in ancient rocks and the genetics of living animals. Research published in Nature Communications combines geology and genetics, showing how change.....»»
Making extremely thing lubricating films predictable: Extension of the Reynolds equation by a non-linear wall slip law
When an electric vehicle accelerates, the motor generates maximum forces and enormous pressures act on the gears of the electric drivetrain. Surface meets surface, metal meets metal. If there were no lubricating film to allow the gears to slide more.....»»
Novel stem cell culture system could lead to future therapies for a variety of disorders
A new study led by UT Southwestern Medical Center molecular biologists presents a novel culture system to grow both embryonic and extraembryonic stem cells, potentially providing important insights into the genesis of congenital malformations and ear.....»»
New modular flow platform for improved SuFEx click chemistry
Researchers at the Flow Chemistry group of the University of Amsterdam's Van 't Hoff Institute for Molecular Sciences have developed a modular flow chemistry platform for a safe and efficient execution of SuFEx (Sulfur(VI) Fluoride Exchange) click ch.....»»
Grinding coffee with a splash of water reduces static electricity and makes more consistent and intense espresso: Study
The fracturing and friction of coffee beans during grinding generates electricity that causes coffee particles to clump together and stick to the grinder. Researchers report Dec. 6 in the journal Matter that coffee beans with higher internal moisture.....»»
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.....»»
"DNA curtain" technology provides real-time visualization of replication for new scientific insights
A research team, led by Professor Ja Yil Lee in the Department of Biological Sciences at UNIST has made a breakthrough in the field of molecular biology. Their research, published in the journal Nucleic Acids Research, has successfully imaged the rea.....»»
Researchers show excited electrons straightening the skewed lattice of perovskite nanocrystals
Researchers from ETH Zurich, Empa and Stanford have taken snapshots of the crystal structure of perovskite nanocrystals as it was deformed by excited electrons. To their surprise, the deformation straightened out the skewed crystal structure rather t.....»»
Superconducting nanowires detect single protein ions
An international research team led by quantum physicist Markus Arndt (University of Vienna) has achieved a breakthrough in the detection of protein ions: Due to their high energy sensitivity, superconducting nanowire detectors achieve almost 100% qua.....»»
When physics meets biology: Prion protein orchestrates liquid–liquid phase separation with copper
In a study published in Science Advances, researchers from the Federal University of Rio de Janeiro (UFRJ) and the German Center for Neurodegenerative Diseases (DZNE-Berlin) shed light on the intricate dance between the prion protein and copper ions.....»»
Could life exist in molecular clouds?
Our search for life beyond Earth is still in its infancy. We're focused on Mars and, to a lesser extent, ocean moons like Jupiter's Europa and Saturn's Enceladus. Should we extend our search to cover more unlikely places like molecular clouds?.....»»
Molecular rulers for high-resolution microscopy
There is good news for researchers working with high-resolution fluorescence microscopy: Biocompatible molecular rulers are available for the first time to calibrate the latest super-resolution microscopy methods......»»
Researchers develop a new approach to polarization-independent LC phase modulation
Liquid-crystal (LC) phase modulators are widely used in optical systems because of their advantages of low power consumption, lightweight, flexible bandwidth adjustment, and non-mechanical movements. However, most LC phase modulators are polarization.....»»
Study finds more stable clocks could measure quantum phenomena, including the presence of dark matter
The practice of keeping time hinges on stable oscillations. In a grandfather clock, the length of a second is marked by a single swing of the pendulum. In a digital watch, the vibrations of a quartz crystal mark much smaller fractions of time. And in.....»»
Google’s DeepMind finds 2.2M crystal structures in materials science win
