Acoustics put a fresh spin on electron transitions
Electrons are very much at the mercy of magnetic fields, which scientists can manipulate to control the electrons and their angular momentum -- i.e. their 'spin.'
Engineers find neat way to turn waste carbon dioxide into useful material
Chemical engineers from UNSW Sydney have developed new technology that helps convert harmful carbon dioxide emissions into chemical building blocks to make useful industrial products like fuel and plastics.
Creative ice cube trays to chill your drink
Don't be square. (David von Diemar via Unsplash/)While the fundamentals of ice don’t change—combine two parts hydrogen and one part oxygen, then chill until solid—the way we shape that ice is limitless. Sometimes...
Researchers mimic nature for fast, colorful 3D printing
Brilliantly colored chameleons, butterflies, opals – and now some 3D-printed materials – reflect color by using nanoscale structures called photonic crystals. A new study that demonstrates how a modified 3D-printing...
First confirmation of new theory by metamaterial
Physicists have experimentally demonstrated a novel effect for the first time by exploiting topological metamaterials.
Physics principle explains order and disorder of swarms
Physicists demonstrate a correlation between the behavior of collective animal systems and a so-called 'critical point'.
Arbiter: Justice Dept. 'abused' power to drop Michael Flynn case
A retired judge appointed to review the Michael Flynn said Wednesday the Justice Department Wednesday showed a "gross abuse" of power in seeking to dismiss charges against the former national...
Freshman chemistry is an exit point for many underrepresented STEM students, study shows
University of Washington study reveals final grades in general chemistry classes dictate whether underrepresented students persist in STEM
Researchers mimic nature for fast, colorful 3-D printing
Brilliantly colored chameleons, butterflies, opals—and now some 3-D-printed materials—reflect color by using nanoscale structures called photonic crystals.
Molecular twist makes one catalyst useful for three hydrogen applications
Scientists from Kyushu University and Kumamoto University in Japan have developed a new catalyst capable of assisting three key reactions for using hydrogen in energy and industry. Inspired by three...
Air Force to review discipline, opportunities for African-American airmen
Air Force officials have ordered an independent review of racial disparity in U.S. Air Force records on military discipline and advancement opportunities, the branch announced this week.
Watch: Barber invents safety shield to protect customers from coronavirus
A New Jersey barber preparing to reopen his shop invented a shield designed to keep salon workers and their customers safe amid the COVID-19 pandemic.

An unusual cobalt compound
A research team has manufactured a novel, highly versatile cobalt compound. The molecules of the compound are stable, extremely compact and have a low molecular weight so that they can...
HBO Max removes 'Gone with the Wind' over 'racist depictions'
HBO Max temporarily pulled Civil War epic "Gone with the Wind" amid ongoing protests over George Floyd's death.
Scientists marry two powerful techniques to pinpoint locations of individual molecules in their cellular neighborhoods
Scientists have married two of today’s most powerful microscopy techniques to make images that pinpoint, for the first time, the identities and precise locations of individual proteins within the detailed...
Watch: Escaped wallaby wrangled in Wisconsin neighborhood
Police responded to a Wisconsin neighborhood to help capture a wallaby that escaped from its owner's yard and went for a hop down the road.
Ford, Volkswagen sign agreement for multiple projects
Ford Motor Company and Volkswagen AG said Wednesday they signed an agreement to collaborate on numerous projects, including creating new commercial vehicles, electric cars and self-driving technology.

Fluid mechanics mystery solved
An environmental engineering professor has solved a decades-old mystery regarding the behavior of fluids, a field of study with widespread medical, industrial and environmental applications.
Liquid metals break down organic fuels into ultra-thin graphitic sheets
For the first time, researchers show the synthesis of ultra-thin graphitic materials at room temperature using organic fuels (which can be as simple as basic alcohols such as ethanol).
Signatures of fractional electronic charge observed in topological insulators
Because electrons -- the subatomic particles that carry electricity -- are elementary particles and cannot be split, fractions of electronic charge are not normally encountered. Despite this, researchers have recently...
Simulations on biologically relevant time scales achieved
Molecular dynamics simulations (MD) have become a ubiquitous tool in modern life sciences. In these simulations, the interactions between atoms and molecules and their resulting spatial movements are iteratively calculated...
First confirmation of new theory by metamaterial
Topological metamaterials are applied as a novel platform to explore and study extraordinary effects. Instead of using natural materials, researchers artificially arrange the constituents of a topological metamaterial in a...
Signatures of fractional electronic charge observed in topological insulators
The charge of a single electron, e, is defined as the basic unit of electric charge. Because electrons—the subatomic particles that carry electricity—are elementary particles and cannot be split, fractions...
