Phys.org / NASA completes Nancy Grace Roman Space Telescope construction
NASA's next big eye on the cosmos is now fully assembled. On Nov. 25, technicians joined the inner and outer portions of the Nancy Grace Roman Space Telescope in the largest clean room at the agency's Goddard Space Flight ...
Phys.org / Astrophysicists test a new piece of the sky to probe dark matter and dark energy
In the leading model of cosmology, most of the universe is invisible: a combined 95% is made of dark matter and dark energy. Exactly what these dark components are remains a mystery, but they have a tremendous impact on our ...
Phys.org / New massive duck-billed dinosaur species identified
There's a new dinosaur species on the block. An international team, including a biologist from Penn State Lehigh Valley, discovered that a 75-million-year-old fossil classified as a different dinosaur is its own massive, ...
Phys.org / Over 16,000 dinosaur footprints identified along a Bolivian shoreline
A fossil site in Bolivia preserves thousands of traces of dinosaurs who walked, ran, and swam along an ancient coastline, according to a study by Raúl Esperante of the Geoscience Research Institute, California, U.S., and ...
Phys.org / Cracking the code of why and when some choose to 'self-handicap'
Partying the night before a big exam. Preparing last-minute for a work presentation. Running a 5K in a 10-pound Halloween costume. All are examples of what psychologists call "self-handicapping"—creating obstacles to success ...
Phys.org / Space debris poses growing threat, but new study suggests cleanup is feasible
High up in Earth's orbit, millions of human-made objects large and small are flying at speeds of over 15,000 miles per hour. The objects, which range from inactive satellites to fragments of equipment resulting from explosions ...
Phys.org / 10-thousand-year-old genomes from southern Africa change picture of human evolution
In southern Africa, a group of people lived in partial isolation for hundreds of thousands of years. This is shown in a new study based on analyses of the genomes of 28 people who lived between 10,200 and 150 years ago in ...
Tech Xplore / Classical Indian dance inspires new ways to teach robots how to use their hands
Researchers at the University of Maryland, Baltimore County (UMBC) have extracted the building blocks of precise hand gestures used in the classical Indian dance form Bharatanatyam—and found a richer "alphabet" of movement ...
Phys.org / Free climbers discover remnants of ancient sea turtle stampede in Italy
Rocks have been found to hold many traces of Earth's ancient history, but usually geologists have to seek them out. Every once in a while, however, these imprints of times past are found by unsuspecting visitors. This occurred ...
Phys.org / Lightning channels reveal hidden bursts: Lateral negative re-discharges observed for first time
A new study led by researchers from the Institute of Atmospheric Physics of the Chinese Academy of Sciences (CAS) has uncovered the first observational evidence of lateral negative re-discharges occurring on negative leader ...
Tech Xplore / Aerial microrobot can fly as fast as a bumblebee
In the future, tiny flying robots could be deployed to aid in the search for survivors trapped beneath the rubble after a devastating earthquake. Like real insects, these robots could flit through tight spaces larger robots ...
Phys.org / Smart material instantly changes colors on demand for use in textiles and consumer products
Scientists have developed a revolutionary technique for creating colors that can change on command. These are structural colors that don't rely on dyes or pigments and can be used for display signage, adaptive camouflage ...
