Indigenous people of the Andes were the first to domesticate the potato, making the starch-rich crop a dietary staple for this high-altitude population long before it spread to the rest of the world. Today, their descendants ...
Tech Xplore / Focused helium ions create ferroelectric regions in aluminum nitride for lower-power chips
Scientists at the Department of Energy's Oak Ridge National Laboratory have shown for the first time that ferroelectricity can be directly written into aluminum nitride using a tightly focused helium ion beam at the Center ...
Phys.org / Every dollar spent on forest fuel treatments saves $3.75 in wildfire damages, study finds
Every dollar spent on forest fuel treatments saves about $3.75 in wildfire damages, according to a new study, led by researchers at the University of California, Davis, of nearly 300 fires in the western United States. The ...
Medical Xpress / Scientists finally see inside the 'black box' of depression treatment
Transcranial magnetic stimulation (TMS) is a noninvasive, FDA-approved therapy that uses brief magnetic pulses to treat depression, particularly in patients who do not respond to medication. Yet scientists have long struggled ...
Phys.org / Thawing Arctic soil awakens only half of soil microbes, new study reveals
As the Arctic warms at an unprecedented rate, frozen soils that have remained locked in ice for most of the year are now thawing for longer periods. Yet new research led by an international team including scientists from ...
Phys.org / Almost all plant-based meat alternatives contain mycotoxins, new research finds
New research into plant-based food and drinks has found a prevalence of mycotoxins—naturally occurring poisonous compounds produced by fungi—in hundreds of vegetarian and vegan products. A total of 212 plant-based meat alternatives ...
Phys.org / Archaeologists reveal secrets of prehistoric human-made island
Archaeologists from the University of Southampton have excavated and recorded a large timber platform hidden beneath what today appears to be a stone-built island, located in a Scottish loch. They used a technique called ...
Phys.org / Medieval jaw reveals Scotland's first known dental bridge made from 20-carat gold
Without good dental care, teeth tend to suffer. An abundance of archaeological evidence has shown that poor oral health was common throughout history. And unsurprisingly, there have been many attempts at dental restoration ...
Phys.org / Why plant extinctions may rise by 2100 even if species keep shifting ranges
No matter how fast a species under threat can move, escape can only be successful if the new destination can meet its needs. An ecological modeling study from the University of California, Davis, found that 7% to 16% of global ...
Medical Xpress / One dose of psilocybin changes the human brain, leading to higher entropy
Researchers at UC San Francisco and Imperial College London have shown that a single dose of psilocybin, the psychedelic compound found in magic mushrooms, causes likely anatomical brain changes that last for up to a month ...
Medical Xpress / Garlic-derived compound shows potential to improve muscle health during aging
Can a compound derived from a common kitchen ingredient help support muscle health during aging? A new study suggests it can. The study reveals that S-1-propenyl-L-cysteine (S1PC), a bioactive compound found in aged garlic ...
Phys.org / Trafficked pangolin DNA reveals hotspots of illegal wildlife trade
Small samples of DNA can reveal hotspots and trade routes in the illegal wildlife trade, according to a study published in the open-access journal PLOS Biology by Sean Heighton and Philippe Gaubert of the University of Toulouse ...
