Clocking electron movements inside an atom
Hard X-ray free-electron lasers (XFELs) have delivered intense, ultrashort X-ray pulses for over a decade. One of the most promising applications of XFELs is in biology, where researchers can capture images down to the atomic scale even before the ra.....»»
Researchers map 33 new big game migrations across American West
A new set of maps that document the movements of ungulates was published today in the fourth volume of the Ungulate Migrations of the Western United States. The maps in this collaborative U.S. Geological Survey report series reveal the migration rout.....»»
Advanced microscopy technique offers a new look inside cells
Imagine tuning into a football game, but all of the players are invisible except for the two quarterbacks. Without being able to see the orchestrated movements of the full teams, this would be a very confusing game to watch......»»
Making ultra-fast electron measurements in multiple directions to reveal the secrets of the aurora
The energetic electrons that drive the aurora borealis (the northern lights) have a rich and very dynamic structure that we currently do not fully understand. Much of what we know about these electrons comes from instruments that have fundamental lim.....»»
Electro-optic 3D snapshot of a laser wakefield accelerated kilo-ampere electron bunch
Invented by T. Tajima and J. Dawson, laser wakefield acceleration (LWFA) harnesses the power of high-intensity laser pulses to drive plasma waves with acceleration gradients orders of magnitude higher than conventional RF-based accelerators......»»
New technique lets scientists create resistance-free electron channels
An international research team led by Lawrence Berkeley National Laboratory (Berkeley Lab) has taken the first atomic-resolution images and demonstrated electrical control of a chiral interface state—an exotic quantum phenomenon that could help res.....»»
Atom interferometer charters Navy"s inertial navigation path to reduce drift
U.S. Naval Research Laboratory (NRL) researchers have developed a patent-pending Continuous 3D-Cooled Atom Beam Interferometer derived from a patented cold and continuous beam of atoms to explore atom-interferometry-based inertial measurement systems.....»»
A simple, inexpensive way to make carbon atoms bind together
The active ingredient in many drugs is what's known as a small molecule: bigger than water, much smaller than an antibody and mainly made of carbon. It's tough, however, to make these molecules if they require a quaternary carbon—a carbon atom bond.....»»
Research demonstrates anatase supported Ni single-atom catalysts for propane dehydrogenation
Propylene is one of the most important petrochemical raw materials, ranging second after ethylene. To meet the ever-increasing demand, alternative technologies for propylene production are in urgent need, among which the propane dehydrogenation (PDH).....»»
Small satellite launch advances comms experimentation, international collaboration
In the dark, early morning sky of March 21 over NASA's Wallops Island Flight Facility on the Virginia coast, a Rocket Lab Electron rocket carried a National Reconnaissance Office (NRO) manifest featuring three collaborative research missions into low.....»»
Venomous snakes could start migrating in large numbers if we hit 5ºC warming, predict scientists
A global group of scientists has predicted that climate change may cause dramatic movements in venomous snake populations across many countries in Africa. The scientists took into account climate change predictions about changes to the current habita.....»»
Solar eclipse could scramble bird behavior
On April 8, the shadow of a total solar eclipse will race across North America. At the same time, researchers from the Cornell Lab of Ornithology and partners will be hurrying to measure the impact of daytime darkness on the movements of birds, bats,.....»»
Team modulates electronic state of single-atom catalysts by CO molecular decoration for efficient methane conversion
Direct methane conversion has advantages such as low energy consumption, fewer processes, and better economics. However, it is difficult to activate methane at room temperature due to the high dissociation energy of C-H bonds of methane. Additionally.....»»
Electron-bending effect could boost computer memory
A new magnetic material developed by RIKEN physicists could boost computer memory storage by enabling higher memory density and faster memory writing speeds. Their research has been published in the journal Nature Communications......»»
Rocket Report: Starship could fly again in May; Ariane 6 coming together
"I think we’re really going to focus on getting reentry right." Enlarge / Nine kerosene-fueled Rutherford engines power Rocket Lab's Electron launch vehicle off the pad at Wallops Island, Virginia, early Thursday. (credit: Brad.....»»

Regulating atomic Fe-Rh site distance for efficient oxygen reduction reaction
In a study published in the journal Science China Chemistry, the authors systematically design and investigate the site-distance effect of Fe-Rh atom catalysts (Fe-Rhx@NC) supported by N-doped graphene for ORR by an integrated theoretical and experim.....»»
Molecular crystal motors move like microbes when exposed to light
At first glance, Rabih O. Al-Kaysi's molecular motors look like the microscopic worms you'd see in a drop of pond water. But these wriggling ribbons are not alive; they're devices made from crystallized molecules that perform coordinated movements wh.....»»
Quantum dance to the beat of a drum: Researchers observe how energy of single electron is tuned by surrounding atoms
Physicists at the University of Regensburg have choreographed the shift of a quantized electronic energy level with atomic oscillations faster than a trillionth of a second......»»
Scientists develop deep learning method to design bilin-binding proteins
David Baker's group at the University of Washington, Seattle, U.S., have developed a novel deep learning method, RoseTTAFold All-Atom (RFAA), for prediction and design of complexes of proteins, small molecules, and nucleic acids. Subsequently, they d.....»»
