Medical Xpress / Cognition and consciousness arise from analog computations, says new theory
A new theory, published in The Journal of Neuroscience by three scientists at the Picower Institute for Learning and Memory at MIT, offers an explanation of how the brain produces cognition and consciousness: It uses traveling ...
Phys.org / Alternative mRNA modification lets ribosomes move nearly twice as fast
In a new study, scientists from Johns Hopkins Medicine report that an experimental mRNA-based platform has the potential to help deliver next-generation mRNA therapeutics, including vaccines to fight infectious diseases, ...
Phys.org / Welcome to the jungle: Newly discovered snake named after Slash from Guns N' Roses
Slash, aka Saul Hudson, is probably best known as the guitarist for Guns N' Roses. But there's more to Slash than his music. He's also a lifelong reptile lover and an avid supporter of zoos and museums. And now, he's the ...
Phys.org / How we found Haida Gwaii's first marbled murrelet nest in more than 30 years
Scrambling through dense salal in the dark, weaving between the majestic western red cedars of northern Haida Gwaii, I could barely imagine where we were just days before—crossing Dixon Entrance off the coast in an open skiff, ...
Medical Xpress / Robotic assisted knee replacement gives same patient outcomes as surgeon-only procedure in clinical trial
Robotic assistance is increasingly used in knee replacement surgery worldwide: in 6% of procedures in the UK, compared with 16% in the U.S. and 42% in Australia. The aim is to help surgeons place knee replacements more precisely ...
Phys.org / Volcano myths unravel, from 'smoke' plumes to Yellowstone catastrophe claims
Volcanoes emit smoke. Beneath a volcano lies a huge chamber filled with liquid magma. A series of earthquakes means an eruption is imminent. And if a "supervolcano" like Yellowstone were to awaken, a global catastrophe would ...
Medical Xpress / Microglia caught eating living motor neurons in ALS mice via unexpected immune pathway
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that, according to the CDC, currently affects around 35,000 Americans—with 5,000 more diagnosed each year. Risk climbs with age, and treatments only slow ...
Phys.org / Rescue mission is called off for NASA's aging Swift space telescope
The mission to save NASA's sinking Swift Observatory was called off Wednesday, dooming the telescope to a fiery reentry later this year.
Phys.org / Dark Stars may have left gravitational-wave echoes across the universe
A mysterious background of extremely low-frequency gravitational waves detected by networks of pulsars may carry information about events that began more than 13 billion years ago—including the formation of some of the first ...
Phys.org / North Sea wind farm expansion may shift rain offshore, simulations suggest
Offshore wind farms are a key pillar of the energy transition. The European Union plans to expand offshore wind capacity in the North Sea by 2050. A new study by the Helmholtz-Zentrum Hereon indicates that a very extensive ...
Phys.org / Breaking up of swan families in winter disrupts spring migration
Young Bewick's swans only survive their first spring migration if they stay with their parents long enough. If they lose their parents in winter, they leave later and are unable to keep up with the rest of the population. ...
Phys.org / Thinner lenses, brighter colors: Metalens research clears two hurdles for AR and VR glasses
AR and VR glasses once seen only in science fiction may soon be realized not as bulky stacks of lenses but as a single eyeglass-like optical element. That future is now closer to reality.
