Medical Xpress / Adversarial AI framework reveals mechanisms behind impaired consciousness and a potential therapy
Consciousness, and the ways in which it can become impaired after certain brain injuries, are not well understood, making disorders of consciousness (DOC), like coma, vegetative states and minimally conscious states difficult ...
Phys.org / Continued monitoring of sunken Soviet submarine shows ongoing radioactive leakage, but little impact
In 1989, the Soviet nuclear-powered attack submarine Komsomolets sank to the bottom of the Norwegian Sea, along with its nuclear reactor and two nuclear warheads onboard. Komsomolets was constructed with a titanium alloy ...
Phys.org / Python scales host microstructures that block bacterial biofilms—revealing potential for antimicrobial materials
Materials inspired by nature, or biomimetic materials, are nothing new. Scientists have designed water-resistant materials inspired by lotus leaves and rose petals, unsinkable metals based on the air-trapping, buoyant abilities ...
Phys.org / Two buried Iron Age hoards reveal first evidence for four-wheeled wagons in Britain
In 2021, a man named Peter Heads made a fascinating discovery while using his metal detector in Melsonby, North Yorkshire in the UK. The find prompted him to contact Tom Moore at the Department of Archaeology at Durham University, ...
Tech Xplore / Humanoid robot learns impressive tennis skills from imperfect human motion
Roboticists have struggled to get humanoid robots to effectively replicate athletic sports skills, such as those needed for tennis. These sports require highly dynamic motion, quick reactions, and high precision that robots ...
Phys.org / Platypus fur adds another strange feature to an increasingly long list
The combination of a beaver-like body and duck-like bill of the platypus (Ornithorhynchus anatinus) is only the first of a long list of strange features on this unique creature. These odd mammals also lay eggs, have venomous ...
Medical Xpress / Smartwatch and blood test data combine to better predict insulin resistance and diabetes
Around 20–40% of the general population are estimated to have insulin resistance—a condition where insulin begins to be less effective in the body, and glucose regulation becomes more difficult. Eventually, this can lead ...
Phys.org / ISS study identifies thresholds for muscle atrophy and fiber changes in reduced gravity
It's well known that spaceflight causes muscle atrophy and other biological changes in reduced gravity, and especially in near-zero gravity (microgravity) environments. However, the gravity threshold needed to maintain sufficient ...
Phys.org / Quantum computers must overcome major technical hurdles before tackling quantum chemistry problems
Although the potential applications of quantum computing are widespread, a new feasibility study suggests quantum computers still face major hurdles in solving quantum chemistry problems. The study, published in Physical ...
Medical Xpress / A single dose of psilocybin is more effective than nicotine patches for quitting smoking, study suggests
A new study, published in JAMA Network Open, reports the outcome of a clinical trial out of Johns Hopkins University assessing the effectiveness of psilocybin as a treatment for smokers attempting to quit. The trial compared ...
Phys.org / Nocturnal ants use lunar compass and sophisticated calculations to travel at night
It's well known that many animals, including migratory birds, butterflies, and even fish, use the sun for navigational purposes. Nocturnal animals are dealt a more difficult hand, however, as the moon's path is far more variable. ...
Phys.org / New exoplanet survey method finds high rates of closely orbiting planets
Up until now, exoplanet surveys have mostly focused on nearby, bright stars that are sun-like or are red dwarfs, which are known to frequently host planets. While astronomers have discovered thousands of planets this way, ...
Phys.org / Nearby red dwarf star hosts at least four planets—with one in the habitable zone
In 2020, a study confirmed that two planets orbited the nearby red dwarf, GJ 887. Now, astronomers have confirmed the existence of two additional planets orbiting GJ 887 in a new study published in Astronomy and Astrophysics. ...
Phys.org / Inland China experienced typhoon-related population decline 3,000 years ago, according to 'oracle bones,' AI and physics
Evidence suggests that China's "cradle of civilization" experienced marked climate disasters and social upheavals during the mid-late Holocene (around 3,000 years ago). However, the direct causes and impacts of these ancient ...
Medical Xpress / A safer, more effective atrial fibrillation treatment method using magnetic gel may be on the way
Atrial fibrillation is a common heart condition characterized by a rapid, irregular heartbeat stemming from the heart's upper chamber. It is a leading cause of stroke from clots that form in a small pouch of the heart called ...
