Researchers at the University of Bath have found a way to make ‘single-crystal flake’ devices that are so thin and free of defects, they have the potential to outperform components used today in quantum computer circuits. The study is published this month in the journal Nano Letters. The team from the university’s Department of Physics made its discovery […]

Classic antidepressants could help improve modern cancer treatments. They slowed the growth of pancreatic and colon cancers in mice, and when combined with immunotherapy, they even stopped the cancer growth long-term. In some cases the tumors disappeared completely, researchers at UZH and USZ have found. Their findings will now be tested in human clinical trials. […]

In the Middle Bronze Age (about 3600 years ago or roughly 1650 BCE), the city of Tall el-Hammam was ascendant. Located on high ground in the southern Jordan Valley, northeast of the Dead Sea, the settlement in its time had become the largest continuously occupied Bronze Age city in the southern Levant, having hosted early […]

While research has shown that poor cardiovascular health can damage blood flow to the brain increasing the risk for dementia, a new study led by UC San Francisco indicates that poor mental health may also take its toll on cognition. The research adds to a body of evidence that links depression with dementia, but while […]

As early as 18,000 years ago, humans in New Guinea may have collected cassowary eggs near maturity and then raised the birds to adulthood, according to an international team of scientists, who used eggshells to determine the developmental stage of the ancient embryos/chicks when the eggs cracked. “This behavior that we are seeing is coming […]

Rising consumer concern over data privacy has led to a rush of “right to be forgotten” laws around the world that allow individuals to request their personal data be expunged from massive databases that catalog our increasingly online lives. Researchers in artificial intelligence have observed that user data does not only exist in its raw […]

Biomedical engineers and surgeons at Duke University and UCLA have demonstrated an antibiotic coating that can be applied to orthopedic implants minutes before surgery that eliminates the chances of an infection around the implant. In early trials in mice, the coating prevented all subsequent infections, even without infusions of antibiotics into the bloodstream, which is […]

Although female giraffes have closer “friends” than male giraffes, male giraffes have more “acquaintances” than females, according to a new study by an international team that includes a Penn State biologist. The study demonstrates that giraffes form a complex multilevel society that is driven by differences in the social connections among individuals, which could have […]

[embedded content] Hyenas are frequently vilified and often feared. Hemingway once described the hyena as a stinking, foul devourer of the dead, with jaws that crack the bones the lion leaves. But a new study concludes that spotted hyena scavenging provides significant public health and economic benefits to the African cities they roam. In a […]

Low-carbohydrate diets are popular for weight loss and diabetes control. However, for most of the past 50 years, medical and public health experts have instead embraced low-fat diets, concerned about the health effects of saturated fats on cardiovascular risk factors like LDL cholesterol. As a result, low-fat and fat-free foods have proliferated — many of […]
