Tiny fluorescent semiconductor dots, called quantum dots, are useful in a variety of health and electronic technologies but are made of toxic, expensive metals. Nontoxic and economic carbon-based dots are easy to produce, but they emit less light. A new study that uses ultrafast nanometric imaging found good and bad emitters among populations of carbon dots. This observation suggests that by selecting only super-emitters, carbon nanodots can be purified to replace toxic metal quantum dots in many applications, the researchers said.

Stocks are rising broadly on Wall Street Monday even as Apple and several other technology companies lag behind.

Using a nanopore, researchers have demonstrated the potential to reduce the time required for sequencing a glycosaminoglycan—a class of long chain-linked sugar molecules as important to our biology as DNA—from years to minutes.

'Pompeii of prehistoric plants' unlocks evolutionary secret: study  Phys.org

Life expectancy in the United States dropped in 2020 due to COVID-19, but, for American adults without a college degree, the increase in mortality in adulthood occurred even earlier, according to a new study authored by Anne Case and Sir Angus Deaton of Princeton University.

Malaria is the deadliest pathogen in human history. Nearly half the people on Earth are at risk of contracting the disease from the parasites that cause it. But humans aren't the only ones who can get these parasites—different forms are found in other animals, including birds. By studying the DNA of those strains, scientists can get a better picture of how malarial parasites live, which may give clues on how to stop the disease. In a new paper in PNAS, researchers analyzed blood samples of more than... Читать дальше...

However, the bull run in commodities, especially oil, is now making energy the... Читать дальше...
