Phys.org / North Pacific winter storm tracks shifting poleward much faster than predicted
Alaska's glaciers are melting at an accelerating pace, losing roughly 60 billion tons of ice each year. About 4,000 kilometers to the south, in California and Nevada, records for heat and dryness are being shattered, creating ...
Phys.org / Optics research uses dim light to produce bright LEDs
Researchers at Princeton and North Carolina State University have developed a technique that substantially improves the ability to convert low-energy light into a high-energy version. The method has immediate applications ...
Phys.org / Plasma rings around M dwarf stars offer new clues to planetary habitability
How does a star affect the makeup of its planets? And what does this mean for the habitability of distant worlds? Carnegie's Luke Bouma is exploring a new way to probe this critical question—using naturally occurring space ...
Phys.org / THz spectroscopy system bypasses long-standing tradeoff between spectral and spatial resolution
Terahertz (THz) radiation, which occupies the frequency band between microwaves and infrared light, is essential in many next-generation applications, including high-speed wireless communications, chemical sensing, and advanced ...
Phys.org / 60,000-year-old traces of world's oldest arrow poison reveal early advanced hunting techniques
Researchers from South Africa and Sweden have found the oldest traces of arrow poison in the world to date. On 60,000-year-old quartz arrowheads from Umhlatuzana Rock Shelter in KwaZulu-Natal, South Africa, researchers have ...
Tech Xplore / Grasshopper wings inspire gliding robot design
A collaboration between Princeton University engineers and entomologists at the University of Illinois Urbana-Champaign began with the researchers chasing grasshoppers in a hot parking lot. Their eventual focus on the hindwings ...
Phys.org / The mechanical ratchet: A new mechanism of cell division
Cell division is an essential process for all life on Earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive—particularly for egg-laying species.
Medical Xpress / Single-dose oral cholera vaccine completes phase 1 trial with promising results
A team of scientists and physicians at Mass General Brigham has developed a single-dose oral cholera vaccine and tested it in a phase 1 clinical trial, with results published in The Lancet Infectious Diseases.
Phys.org / Engineers create water-saving sand layer to improve plant resilience during drought
The Anasazi, a once-flourishing tribe in the American Southwest, lived on bounties of corn, squash and beans. In 1276 A.D., however, a long, unforgiving drought made agriculture untenable, forcing them to migrate away from ...
Medical Xpress / Whooping cough vaccination for pregnant women strengthens babies' immune systems, international study shows
International research led by Radboud University Medical Center shows that vaccinating women during pregnancy leads to the transfer of antibodies to their newborns. Antibodies from the mother are transferred to the baby through ...
Tech Xplore / Laser cladding technology on track to improve railway repair
The University of Sheffield Rail Group hosted industry partners at British Steel on 7th November to see laser-clad field-demonstrations, which showed how additive manufacturing can repair railway infrastructure and provide ...
Phys.org / Creating psychedelic-like molecules by shining light on life's basic building blocks
UC Davis researchers have developed a new method that uses light to transform amino acids—the building blocks of proteins—into molecules that are similar in structure to psychedelics and mimic their interaction with the ...
