Early Medieval Europe is often viewed as a time of cultural stagnation, often given the misnomer "dark age". However, the analysis shows that new ideas can spread quickly when communities are connected and a surprisingly uniform culture emerges in Europe. Dr. Emma Brownlee, Department of Archeology, Cambridge University, investigated how an important change in Western […]
In addition to heat and high pressure, small electrical fields can also play a decisive role in the formation of this extremely hard carbon compound. – ScienceDaily
Like graphite, diamond is a special form of carbon. Its cubic crystal structure and its strong chemical bonds give it its unique hardness. For thousands of years it has been in demand as both a tool and a beauty thing. It was only in the 1950s that it became possible to artificially manufacture diamonds. Most […]
The study reveals two different origins of the vital element on today's planet – ScienceDaily
Where did the earth's nitrogen come from? Scientists from Rice University show that a primary source of the indispensable building block for life was close to home. The isotopic signatures of nitrogen in iron meteorites indicate that Earth likely collected its nitrogen not only from the region beyond Jupiter's orbit, but also from the dust […]
Production of green hydrogen by solar radiation from nanomaterials – ScienceDaily
A research team from the National Research Institute (INRS) has teamed up with French researchers from the Institute of Chemistry and Processes for Energy, Environment and Health (ICPEES), a joint research laboratory of the CNRS University of Strasbourg, to pave the way for green hydrogen production . This international team has developed new light-sensitive nanostructured […]
Wild colonies provide clues for improving honeybees' tolerance to pathogens – ScienceDaily
Understanding the genetic and environmental factors that allow some wild honeybee colonies to tolerate pathogens and survive the winter without beekeeping management can lead to breeding stocks that improve the survival of managed colonies, according to a study by researchers at Penn State College of Agricultural Sciences. Feralization occurs when previously domesticated organisms escape into […]
Study compares low-fat plant-based diets to low-carb animal diets – ScienceDaily
People on a low-fat, plant-based diet ate fewer calories per day, but had higher levels of insulin and blood sugar than those on a low-carb animal-based diet. This was the result of a small but highly controlled study by the National Institute of Health. Led by researchers from the National Institute for Diabetes and Digestive […]
Info-rich bubbles respond to antibiotics – ScienceDaily
Previously only considered as dumped waste products of cell life, bacterial membrane vesicles (MVs) have become an exciting new avenue of research because of the wealth of biological information they pass on to other bacteria and other cell types. These tiny particles, which are produced by most bacteria, can detach themselves from the outer cell […]

Indigenous peoples' land may be home to a significant proportion of threatened and endangered species worldwide, according to research conducted by the University of Queensland. Dr. UQ's Chris O & # 39; Bryan and his team conducted the first comprehensive analysis of land mammal composition in mapped indigenous lands. "These areas cover more than a […]
New research could influence efforts to restore fisheries in the Great Lakes – ScienceDaily
In the dark waters of Lake Superior, a species of fish that has been adapted to regain a genetic trait that may have helped their ancient ancestors see in the ocean, according to a study. Research is focused on kiyis, who inhabit Lake Superior at depths of around 80 to over 200 meters. Known to […]
Animal and human data reveal a new target for reversing the age-related decline – ScienceDaily
A new study shows that humans express a powerful hormone while exercising, and that treating mice with the hormone improves exercise capacity, capacity and fitness. Researchers say the results offer new avenues to address age-related physical decline. The research published on Wednesday in Nature communicationshows a detailed look at how the mitochondrial genome encodes instructions […]
