Milestone in quantum standardization

Researchers have developed a method that could pave the way to establishing universal standards for measuring the performance of quantum computers. The new method, called cycle benchmarking, allows researchers to assess the potential of scalability and to compare one quantum platform against another.

High amounts of screen time begin as early as infancy

Children's average daily time spent watching television or using a computer or mobile device increased from 53 minutes at age 12 months to more than 150 minutes at 3 years, according to a recent analysis. By age 8, children were more likely to log the highest amount of screen time if they had been in home-based childcare or were born to first-time mothers.

First recording of a blue whale's heart rate

With a lot of ingenuity and a little luck, researchers monitored the heart rate of a blue whale in the wild. The measurement suggests that blue whale hearts are operating at extremes -- and may limit the whale's size.

Dinosaur skull turns paleontology assumptions on their head

A team of researchers has unearthed a well-preserved Styracosaurus skull -- and its facial imperfections have implications for how paleontologists identify new species of dinosaurs. Nicknamed Hannah, the dinosaur was a Styracosaurus -- a horned dinosaur over five meters in length with a fan of long horns. Paleontologists have learned much from those horns -- because they aren't symmetrical.

A little prairie can rescue honey bees from famine on the farm

Scientists placed honey bee hives next to soybean fields in Iowa and tracked how the bees fared over the growing season. To their surprise, the bees did well for much of the summer. The colonies thrived and gained weight. But in August, the trend reversed. By mid-October, most of the honey was gone and the overwintering brood was malnourished, the team discovered. Placing the hives near restored...

Liquid-liquid transitions crystallize new ideas for molecular liquids

Researchers demonstrated that liquid-liquid transitions of a molecular liquid were coupled to crystallization behavior. The team was able to enhance the crystallization of triphenyl phosphite by applying heat treatments at temperatures relevant to the liquid phase transitions. The findings could lead to better control of crystallization in applications in science and technology, for example, in...

Locking up fats in CAGEs to reduce obesity

When fresh foods aren't available, how can people with obesity achieve a healthy weight? A new orally administered liquid reduces weight gain by 12% in rats fed high-fat diets without causing side effects, pointing to a possible therapy.

How mantis shrimp make sense of the world

A new study provides insight into how the small brains of mantis shrimp - fierce predators with keen vision that are among the fastest strikers in the animal kingdom - are able to make sense of a breathtaking amount of visual input.

Gut microbes alter characteristics of norovirus infection

The highly contagious norovirus causes diarrhea and vomiting and is notorious for spreading rapidly through densely populated spaces, such as cruise ships, nursing homes, schools and day care centers. There are no treatments for this intestinal virus. A new study has shown that gut microbes can tamp down or boost the severity of norovirus infection based on where along the intestine the virus...

Living at the edge of an active volcano: Risk from lava flows on Mount Etna

On Mt. Etna volcano, inhabited areas have been inundated repeatedly by lava flows in historical times. The increasing exposure of a larger population, which has almost tripled in the area around Mt. Etna during the last 150 years, has resulted from on a poor assessment of the volcanic hazard and risk, allowing inappropriate land use in vulnerable areas.

Rapamycin may slow skin aging

The search for youthfulness typically turns to lotions, supplements, serums and diets, but there may soon be a new option joining the fray. Rapamycin, a FDA-approved drug normally used to prevent organ rejection after transplant surgery, may also slow aging in human skin, according to a new study.
