Space Force flies through Twitter flak after unveiling camo uniforms in earthy tones

The newly minted U.S. Space Force unveiled its uniform on Friday — and defended its fashion statement against Twitter criticism that the camouflage color scheme should have been more spacey. Less than a month after the sixth branch of the U.S. armed forces came into existence, the Space Force showed off the utility uniform in a tweet, saying that the service's nametape and U.S. Space Command...

New ORNL software improves neutron spectroscopy data resolution

Neutron spectroscopy is an important tool for studying magnetic and thermoelectric properties in materials. But often the resolution, or the ability of the instrument to see fine details, is too coarse to clearly observe features identifying novel phenomena in new advanced materials.

Scientists seek rare species survivors amid Australia flames

Australia's unprecedented wildfires season has so far charred 40,000 square miles (104,000 square kilometers) of brushland, rainforests, and national parks—killing by one estimate more than a billion wild animals. Scientists fear some of the island continent's unique and colorful species may not recover. For others, they are trying to throw lifelines.

Panicking About Your Kids and Their Phones? The New Research Says Don't.

SAN FRANCISCO -- It has become common wisdom that too much time spent on smartphones and social media is responsible for a recent spike in anxiety, depression and other mental health problems, especially among teenagers.But a growing number of academic researchers have produced studies that suggest the common wisdom is wrong.The latest research, published Friday by two psychology professors, combs...

Laser diode emits deep UV light

Researchers say they have designed a laser diode that emits the shortest-wavelength ultraviolet light to-date, with potential applications in disinfection, dermatology, and DNA analyses.

In Montreal, Egyptian Mummies, in 3-D, Have Secrets to Share

Egyptian Mummies: Exploring Ancient Lives is the new exhibition at the Museum of Fine Arts in Montreal, done with the collaboration of the British Museum. We have a good macro-understanding of ancient Egypt through its architecture, art, economics, and culture from the early dynastic period (3100 b.c. to 2686 b.c.) to the Roman period (30 b.c. — the fall of Antony and Cleopatra — to a.d. 395)....

SpaceX gets ready to rehearse worst-case scenario for Crew Dragon spaceflights

SpaceX and NASA are planning a dress rehearsal for something they hope will never happen: a catastrophic failure at virtually the worst time in the launch of a crewed mission to the International Space Station. Fortunately, the closest things to crew members on this in-flight abort test of the Crew Dragon spaceship are two test dummies, hooked up to sensors that will tell engineers how...

Male sparrows are less intimidated by the songs of aging rivals

Few singers reach their sunset years with the same voice they had in younger days. Singing sparrows are no different. Duke University-led research reveals that elderly swamp sparrows don't sound quite like they used to—nor do they strike the same fear in other males who may be listening in.

Laser diode emits deep UV light

Nagoya University researchers say they have designed a laser diode that emits the shortest-wavelength ultraviolet light to-date, with potential applications in disinfection, dermatology, and DNA analyses.

Male sparrows are less intimidated by the songs of aging rivals

Few singers reach their sunset years with the same voice they had in younger days. Songbirds are no different. New research reveals that elderly swamp sparrows don't sound quite like they used to -- nor do they strike the same fear in other males who may be listening in. Humans are remarkably good at guessing a person's age by their voice. But this is the first time the phenomenon has been...
