New research details a novel method called Repair-seq that reveals in exquisite detail how genome editing tools work.

Throughout Earth's oceans runs a conveyor belt of water. Its churning is powered by differences in the water's temperature and saltiness, and weather patterns around the world are regulated by its activity. Slower ocean circulation as the result of climate change could intensify extreme cold weather in the U.S., research suggests.

Columbus was not the first European to reach the Americas. The Vikings got there centuries beforehand, although exactly when has remained unclear. Here, scientists show that Europeans were already active in the Americas in 1021 AD.

In a novel, broad assessment of bacterial-fungal interactions, researchers using unique bioinformatics have found that fungi host a remarkable diversity of bacteria.

Algorithms and analytics are now common used by professional sports, in sales forecasts, lending decisions and by car insurance providers. Managers and other decision makers no longer simply “go with their gut.” But, new research suggests, doctors often remain reluctant to introduce such information when making medical decisions for patients.

A new perspectives piece relates machine learning to biological learning, showing that the two approaches aren’t interchangeable, yet can be harnessed to offer valuable insights into how the brain works.

According to research, people with elevated blood pressure that falls within the normal recommended range are at risk of accelerated brain aging.

A study shows that daily exposure to chemicals used in the manufacture of plastic food containers and many cosmetics may lead to roughly 100,000 premature deaths among older Americans each year.

With warming climate, summer sea ice in the Arctic has been shrinking fast, and now consistently spans less than half the area it did in the early 1980s. This raises the question: If this keeps up, in the future will year-round sea ice—and the creatures who need it to survive—persist anywhere?

Many variants in the human genome have been linked to type 2 diabetes, but because most do not lie within genes that code for proteins, it’s unclear how they might cause disease. Now an international team, including investigators at Massachusetts General Hospital (MGH), has developed a resource to help uncover the impact of these genetic variants.
