Medical Xpress / Largest US study finds teen cannabis use linked to slower cognitive development
Researchers from University of California San Diego have found that teenagers who begin using cannabis show slower gains in thinking and memory skills as they grow. The study, published in Neuropsychopharmacology, analyzed ...
Phys.org / Universal quantum protocol extracts maximum work without knowing a system's state in advance
A new study published in Nature Communications has shown that in the asymptotic limit, extracting the maximum possible work from many copies of a quantum system does not require knowing exactly what state that system is in.
Phys.org / Sulfur-rich Mercury magmas behave differently than Earth's do
Mercury is a small, rocky planet about which researchers know relatively little. Two missions, taking readings as they passed over the planet, have revealed that Mercury is covered by an iron-poor and sulfur-rich crust. It ...
Phys.org / How poison frogs built a chemical weapons system one evolutionary step at a time
Poison frogs are small and brightly colored amphibians that originate from Central and South America. As suggested by their name, these frogs can release highly toxic chemicals from their skin, which deter and neutralize ...
Phys.org / A light-controlled 'muscle' could give synthetic cells a new way to move
Engineers interested in creating artificial cells to deliver drugs to unhealthy parts of the body face a key challenge: for a cell-like system to move, change shape, or divide, it needs a way to generate force on command.
Phys.org / The Colorado River disappeared from the geological record for 5 million years: Scientists now know where it went
Geologists have solved the mystery of the disappearance from the geological record, millions of years ago, of one of North America's most important waterways: the Colorado River. A paper published in Science shows that the ...
Tech Xplore / Perovskite solar cells reach 26.61% certified efficiency with cesium-doping strategy
Solar cells, devices that convert sunlight into electricity, are now widely used in many countries. While most existing solar cells are based on silicon, energy engineers have been working on other devices made of so-called ...
Phys.org / This protein-engineering breakthrough generates over 10M data points and turbocharges AI in just three days
Protein engineering is a field primed for artificial intelligence research. Each protein is made up of amino acids; to optimize a protein function, researchers modify proteins by switching out one of 20 different amino acids ...
Phys.org / Wafer-scale 2D magnetic films emerge thanks to a new low-defect growth technique
In a major advance, researchers at the Indian Institute of Science (IISc) have devised a method to grow high-quality 2D magnetic materials (2D-MMs) over centimeter-scale wafers. Earlier approaches in the field were limited ...
Medical Xpress / Novel diabetic wound treatment turns cells into manufacturers
Diabetes affects more than 40 million people in the United States, according to the American Diabetes Association. For many, the chronic condition means a lifetime of pain as worsening circulation leads to nonhealing ulcers ...
Phys.org / DNA cracks nutmeg's hidden past, revealing a South Moluccas origin and a prehuman journey north
A sprinkle of nutmeg powder on baked goodies or mashed potatoes can immediately lift the flavor with its warm and sweet aroma. Even though it is used globally, not much is known about the true origins of the nutmeg spice ...
Phys.org / How tiny voids could make fusion targets more stable under powerful shockwaves
Picture two materials sandwiched together. The boundary between them may appear flat, but, in reality, it is full of tiny bumps and dents. Suddenly, the materials are hit with a shockwave. If that wave hits a bump in the ...
