Phys.org / Fossils reveal sea cows have engineered Arabian Gulf's seagrass ecosystems for over 20 million years
Today, the Arabian Gulf is home to manatee-like marine mammals called dugongs that shape the seafloor as they graze on seagrasses. A newly described fossil site in Qatar reveals that ancient sea cows engineered aquatic ecosystems ...
Phys.org / From light to logic: Ultrafast quantum switching in 2D materials
Scientists from the Indian Institute of Technology Bombay have found a way to use light to control and read tiny quantum states inside atom-thin materials. The simple technique could pave the way for computers that are dramatically ...
Medical Xpress / Non-opioid 'pain sponge' therapy shows promise for chronic pain relief and halting cartilage degeneration
SereNeuro Therapeutics, a preclinical biotechnology company developing non-opioid pain therapies, has unveiled new data on a novel approach to chronic pain management and joint tissue preservation. The data highlight SN101, ...
Phys.org / Cosmic gas flows, not collisions, explain Milky Way's double chemical signature
Clues about how galaxies like our Milky Way form and evolve and why their stars show surprising chemical patterns have been revealed by a new study.
Tech Xplore / Vine-inspired robotic gripper gently lifts heavy and fragile objects
In the horticultural world, some vines are especially grabby. As they grow, the woody tendrils can wrap around obstacles with enough force to pull down entire fences and trees.
Medical Xpress / Short-term stress primes immune cells for action in animal models
Stress affects many systems in our body and biologists Marcel Schaaf and Erin Faught at Radboud University are figuring out how that works. Their recent study showed how stress changes behavior by using two different receptors. ...
Phys.org / A partner's death can hit harder when finances are unstable
Grief over the sudden death of a partner leads 1 in 6 surviving partners to experience such severe psychological distress that they begin taking sedatives or antidepressants. If the death also results in a noticeable loss ...
Medical Xpress / Mini-gut model reveals how Ebola and Marburg disrupt the gastrointestinal tract
Ebola (EBOV) and Marburg virus (MARV) are highly lethal viruses that cause severe disease in infected patients by extensively damaging the body. This includes the gastrointestinal tract. Severe diarrhea followed by dehydration ...
Phys.org / DNA origami lattices on silicon open new possibilities for large-scale nanofabrication
A dissertation study at the University of Jyväskylä (Finland) developed two-dimensional fishnet-like structures from DNA origami for silicon surfaces and investigated how different conditions affect their formation. The ...
Phys.org / The 'hobbits' mysteriously disappeared 50,000 years ago. Our new study reveals what happened to their home
About 50,000 years ago, humanity lost one of its last surviving hominin cousins, Homo floresiensis (also known as "the hobbit" thanks to its small stature). The cause of its disappearance, after more than a million years ...
Tech Xplore / New system efficiently explains AI judgments in real-time
A research team led by Professor Jaesik Choi of KAIST's Kim Jaechul Graduate School of AI, in collaboration with KakaoBank Corp, has developed an accelerated explanation technology that can explain the basis of an artificial ...
Medical Xpress / Rats may seek cannabis to cope with stress
It isn't just people—when given the chance, rats may also use cannabis to cope with stress, according to a study by researchers at Washington State University.
