Medical Xpress / Specialized neuron populations in the mouse cortex coordinate to guide correct decisions, study suggests
For decades, neuroscientists have been trying to pinpoint the neural underpinnings of behavior and decision-making. Past studies suggest that specialized groups of neurons in the mammalian brain, particularly in the cortex, ...
Medical Xpress / New insight into how protein TDP-43 affects gene expression in ALS and FTD
Neurodegenerative diseases, such as Alzheimer's disease (AD), amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are medical conditions characterized by the progressive degradation of cells in the brain, ...
Phys.org / Light-triggered nanoscale heating can control communication between nerve cells
Researchers at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, report the successful creation of artificial synaptic vesicles that can be remotely controlled by near-infrared (NIR) light. By embedding ...
Phys.org / Adjustable DNA 'shield' can control timing and rate at which mRNA produces proteins in vivo
mRNA, widely known from the COVID-19 vaccine, is not actually a "therapeutic agent," but a technology that delivers the blueprint for functional proteins in the body and induces therapeutic effects. Recently, its application ...
Phys.org / First fertilizer: A chemical process that may have sparked life on Earth
University of Alberta geochemists have discovered a missing piece to one of the great mysteries of science—the origin of life on Earth.
Tech Xplore / A metamaterial that bridges air and water
Have you ever tried yelling underwater? Not only is it difficult to make the noise, but it is rarely audible to those outside of the water. Sound travels differently in mediums of different densities, and that causes a high ...
Phys.org / Southern Annular Mode in most positive state in 1,000 years, review finds
A new review has revealed that the Southern Annular Mode (SAM), the Southern Hemisphere's most influential climate driver, is now in its most positive state in more than 1,000 years. If greenhouse gas emissions continue to ...
Medical Xpress / Hospital visits for hallucinogen use linked to six-fold higher risk of later mania
People who have received emergency or hospital care in Canada due to hallucinogen use have a six-fold increased risk of receiving care for mania in the next three years, according to a study published in PLOS Medicine by ...
Tech Xplore / Energy-efficient process delivers rare-earth element for magnets
Neodymium is a rare-earth element essential for producing the strongest permanent magnets, which are widespread in defense technologies, hard drives, medical imaging devices, electric vehicle motors, wind turbines and more. ...
Phys.org / Sounding the 6,000-year-old shell trumpets of Catalonia
Archaeologists have played shell trumpets from Neolithic Catalonia, revealing they were highly effective for long-distance communication and may have also been used as musical instruments.
Phys.org / Newly discovered viral enzymes act like molecular scissors to disable immune alarm signals
Viruses and their hosts—whether bacteria, animals, or humans—are locked in a constant evolutionary arms race. Cells evolve defenses against viral infection, viruses evolve ways around those defenses, and the cycle continues.
Phys.org / Social media algorithms target lower-income youth with risky 'easy money' ads, study shows
Young people with fewer financial resources, especially boys, are the most exposed to advertising about how to make easy money. So confirms a pioneering study by Pompeu Fabra University (UPF), which has for the first time ...
