Phys.org / Ancient DNA traces medieval migration from Sweden to Finland
A new study led by the University of Turku provides new insights into the population history of Finland during the Late Iron Age and the Middle Ages. The researchers analyzed the genomes of people who lived in southwestern ...
Phys.org / Global database reveals hidden diversity and potential of deep-sea microbes
The ocean's aphotic zone—the dark, high-pressure region below the surface, where sunlight cannot reach—is home to a vast wealth of microbial life. Yet scientists know relatively little about the genetic makeup, growth and ...
Phys.org / Plasma and electricity convert CO₂ into methanol, butane and other useful chemicals
Carbon dioxide (CO₂) can be harmful to the environment in large amounts but can be used in the production of fuels and other useful chemicals. Doing so isn't easy, though. Now, Yale researchers have developed a new way to ...
Phys.org / Dogs show human-like brain activity when they restrain themselves
When we tell a dog "no" and it resists temptation, what happens in its brain? New research from the Department of Ethology at ELTE and the HUN-REN Research Centre of Natural Sciences suggests that dogs may do more than respond ...
Phys.org / First confirmed Diplodocus outside North America reshapes Late Jurassic migration picture
In a discovery that challenges our understanding of dinosaur distribution during the Late Jurassic period, paleontologists have identified the first evidence of the iconic Diplodocus outside North America.
Phys.org / From war to weather, Australian farmers are planting spring crops in an uncertain world
Australian farmers are heading into spring with an unusual mix of optimism and uncertainty.
Phys.org / When disaster crosses borders, Indonesia's credibility is tested twice
On Sept. 15, the eruption of Mount Anak Krakatau sent volcanic ash up to 15,000 meters (50,000 feet) and produced rumbling heard 700 kilometers (435 miles) away. Eight airports suspended operations, thousands of flights were ...
Phys.org / Iron, sulfur and purple light unlock greener carbon-carbon bond formation
Much of organic chemistry, including the type used to create and alter medicinal drugs, relies on modifying carbon bonds. Rice University's Julian West has been developing a less expensive, faster and more environmentally ...
Medical Xpress / New sepsis guidelines seek to reduce infection's deadly toll
A UVA Health doctor and other leading national experts have developed new guidelines to improve care for patients who develop sepsis, a dangerous full-body infection that kills at least 350,000 Americans every year.
Phys.org / Grass and clover can provide more than animal feed
Growing leys—grass and clover—is nothing new in Swedish agriculture. But in the arable farming regions dominated by cereal production, leys are less common. One reason is that there needs to be a market for what is harvested.
Phys.org / Robots grow and package lettuce year-round in Norway's fully automated farm
Norway's first fully automated facility for vegetable production was put into operation last fall. This spring, the first products hit store shelves.
Phys.org / Early heat waves hit wheat yields hardest but boost resilience to subsequent heat waves
New research published in the Journal of Experimental Botany reveals that wheat crops are more sensitive to grain yield losses from heat waves that occur before reaching their flowering stage than those occurring later. However, ...
