Phys.org / New experiments suggest Earth's core contains up to 45 oceans' worth of hydrogen
Scientists have long known that Earth's core is mostly made of iron, but the density is not high enough for it to be pure iron, meaning lighter elements exist in the core, as well. In particular, it's suspected to be a major ...
Phys.org / The origin of magic numbers: Why some atomic nuclei are unusually stable
For the first time, physicists have developed a model that explains the origins of unusually stable magic nuclei based directly on the interactions between their protons and neutrons. Published in Physical Review Letters, ...
Phys.org / Oldest known reptile skin impressions dated to 298 million years found in Germany
An international research team led by Dr. Lorenzo Marchetti from the Museum für Naturkunde Berlin has described the oldest known impressions of reptile skin from the Thuringian Forest in central Germany. Particularly remarkable ...
Phys.org / White-nose syndrome puzzle solved: Biological mechanisms behind devastating bat disease revealed
Millions of bats in North America have died from white-nose syndrome, and a new study from the University of Waterloo explores why and how the fungal disease has devastated bat populations on this continent, while it has ...
Medical Xpress / Exercise may train the brain to build endurance via SF1 neuron activity
Exercise does more than strengthen muscles; it also rewires the brain. In a study published in Neuron, researchers reveal that the lasting gain in endurance from repeated exercise—such as the ability to run farther and ...
Phys.org / Plants retain a 'genetic memory' of past population crashes, study shows
Researchers at McGill University and the United States Forest Service have found that plants living in areas where human activity has caused population crashes carry long-lasting genetic traces of that history, such as reduced ...
Phys.org / China's emissions policies are helping climate change but also creating a new problem
China's sweeping efforts to clean up its air have delivered one of the biggest public health success stories of recent decades. Since the Air Pollution Prevention and Control Action Plan was launched in 2013, coal-fired power ...
Tech Xplore / Water-based electrolyte helps create safer and long-lasting Zn-Mn batteries
Many countries worldwide are increasingly investing in new infrastructure that enables the production of electricity from renewable energy sources, particularly wind and sunlight. To make the best of these energy solutions, ...
Phys.org / Fentanyl makeover: Core structural redesign could lead to safer pain medications
Fentanyl is one of the most effective drugs for managing severe pain, yet it carries substantial risks of addiction and respiratory depression, the dangerous and sometimes fatal slowed breathing. These safety concerns have ...
Phys.org / How a tiny shrimp could hold the clue to better armor
Modern armor systems do not do a good enough job of protecting humans from blast-induced neurotrauma (brain and eye damage). To improve them, we may have to look to nature. In particular, a tiny shrimp that is able to protect ...
Phys.org / Ancient DNA suggests hunter-gatherers in Europe's lowlands endured until 2500 BCE
Researchers at the University of Huddersfield have used ancient DNA to reveal that hunter-gatherers in one part of Europe survived for thousands of years longer than anywhere else on the continent—and have uncovered the ...
Phys.org / Temperature affects the quality of male frogs' mating calls: Females can hear the difference
A study from the University of California, Davis, found that temperature affects the sound and quality of male frogs' mating calls. In the colder, early weeks of spring, their songs start off sluggishly. In warmer weather, ...
