Medical Xpress / Brain scans reveal link between thinner brain cortex regions and higher psychopathic traits
A team of researchers from Spain was curious to know if people with high psychopathic traits have anomalies in the brain's physical structures, which make them incapable of feeling regret or capable of manipulation and other ...
Phys.org / World Happiness Report highlights social media's negative impact, ranks Finland as happiest country
Heavy social media use contributes to a stark decline in well-being among young people, with the effects particularly worrying in teenage girls in English-speaking countries and Western Europe, according to the World Happiness ...
Medical Xpress / Coping with chronic disease when food is scarce takes its toll on mental health, researchers find
Twenty-five years into her diabetes and youth research, epidemiology professor Angela Liese and her team continue to increase our understanding of this uniquely vulnerable population. The team's recent findings reveal that ...
Phys.org / Sweden's 'old‑growth' natural forests store 83% more carbon than managed woodlands—new study
Most of Europe's original natural forests have been transformed for agriculture and managed forests producing energy, paper, and timber. The few remaining "old-growth" natural forests are relics of the past that illustrate ...
Phys.org / How an RNA-binding protein detects and responds to non-optimal codon usage in human cells
Human genes are written in long strings of three-letter units composed of four different nucleotides. These units—or codons—specify one of many amino acids, the building blocks of proteins. Multiple codons can encode ...
Phys.org / Mosquitoes may hold the key to saving endangered Australian wildlife
Scientists have discovered mosquitoes can act like tiny "flying wildlife surveyors," helping researchers detect elusive and endangered animals in Australia's national parks. A team from Macquarie University and the Department ...
Phys.org / Superconductor advancement could unlock ultra-energy-efficient electronics
Superconducting materials could play a crucial role in the energy-efficient applications of the future. However, several technical challenges still stand in the way of their practical use. Now, researchers at Chalmers University ...
Medical Xpress / Pittsburgh's air pollution estimated to claim 3,000+ lives per year, and EPA rollbacks aren't helping
In October 1948, a thick haze rolled into Donora, Pennsylvania, a steel town in the Monongahela Valley, south of Pittsburgh. For five days, toxic fumes from a zinc smelter—a plant that turns zinc ore into pure zinc metal—poured ...
Phys.org / Ancient brines helped build Idaho's Silver Valley and Cobalt belt
Idaho's Silver Valley has produced about 1.2 billion ounces of silver since the late 1800s, enough to cast a solid cube roughly as tall as a five-story building, along with huge amounts of lead and zinc. Now a new study led ...
Medical Xpress / Pythons' feast-and-famine life hints at new weight loss pathway
Pythons don't nibble. They chomp, squeeze, and swallow their prey whole in a meal that can approach 100% of their body weight. But even as they slither stealthily around the forest, months or even a year may pass between ...
Phys.org / Nanodiamonds and beyond: Designing carbon materials with AI at exascale
Carbon forms the graphite in pencils, the diamonds in jewelry and the molecules that make up every living thing. But under extreme conditions—like the heat and pressure of intense explosions—carbon can transform into ...
Phys.org / Bow and arrow arrived about 1,400 years ago across western North America, study finds
A study clarifies the date of an important technological milestone: the adoption of the bow and arrow in western North America. The replacement of older weapons by bows and arrows occurred independently in several prehistoric ...
