Medical Xpress / Cannabis edibles pose major crash risk
More than 75% of recreational cannabis users aged 19 to 30 crashed in a driving simulation after consuming edibles, a new University of Saskatchewan (USask) study shows.
Medical Xpress / Brain stimulation during sleep boosts weak memories in mice
Manipulating mouse brains during sleep improved their ability to remember new experiences that would normally be forgotten—a finding with important implications for treating Alzheimer's disease and other forms of dementia ...
Phys.org / All-optical modulation in silicon achieved via an electron avalanche process
Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, communication and information ...
Phys.org / Graphene membranes offer efficient, low-cost option for industrial CO₂ capture
Carbon capture is becoming essential for industries that still depend on fossil fuels, including the cement and steel industries. Natural-gas power plants, coal plants, and cement factories all release large amounts of CO₂, ...
Phys.org / Astronomers create first map of the sun's outer boundary
Astronomers have produced the first continuous, two-dimensional maps of the outer edge of the sun's atmosphere, a shifting, frothy boundary that marks where solar winds escape the sun's magnetic grasp. By combining the maps ...
Medical Xpress / Plasma p-tau217 can reliably detect preclinical Alzheimer disease
Plasma phosphorylated tau 217 (p-tau217) can reliably detect Alzheimer disease (AD) pathology in the preclinical stage, according to a meta-analysis published online Dec. 1 in JAMA Neurology.
Medical Xpress / US Senate set to sink twin health plans as time bomb ticks
US senators were set to vote Thursday on dueling health care plans that are both expected to be rejected, with millions of Americans facing soaring premiums and the issue poised to be a major flashpoint in next year's midterm ...
Tech Xplore / Carbon capture made easier: Simple additive could slash costs for industrial plants
Capturing carbon dioxide from industrial plants is an important strategy in the efforts to reduce the impact of global climate change. It's used in many industries, including the production of petrochemicals, cement, and ...
Medical Xpress / 'Vaccines do not cause autism': WHO
A new analysis by the World Health Organization reaffirmed there is no link between vaccines and autism—contrary to theories being propagated in the United States.
Phys.org / Shape-shifting cell channel reveals new target for precision drugs
From small ions to large molecules, cellular gates control what can pass in and out of cells. But how one such gate, called pannexin-1 (PANX1), can handle vastly different cargo sizes has remained a long-standing mystery.
Phys.org / Hidden fuel for ocean microbes: Urea emerges as key energy source for marine ammonia oxidizers
Ammonia-oxidizing archaea (AOA) are some of the most abundant microorganisms in the ocean and play a key role in nitrogen cycling. Yet, despite their ubiquity, scientists have long puzzled over how these microbes can flourish ...
Tech Xplore / These are the key AI players on the cover of Time's 'Architects of AI' magazine
Accompanying Time's annual person of the year selection Thursday is a magazine cover that resembles the "Lunch Atop a Skyscraper" photograph from the 1930s showing eight of the " Architects of AI " sitting on the beam.
