Two NASA astronauts are taking a spacewalk outside the International Space Station today (Jan. 15), and you can watch all the action live online.

For the first spacewalk of the year, NASA astronauts Christina Koch and Jessica Meir will spend about 6.5 hours working in the vacuum of space to continue replacing old nickel-hydrogen batteries on the station’s solar arrays with new lithium-ion batteries. The spacewalking duo began working to replace these batteries during a spacewalk together on Oct. 18, and that was the first all-woman spacewalk in history.

What could this tell us about the aging process in humans?

Researchers are busy analysing some of the final data sent back from the Cassini spacecraft which has been in orbit around Saturn for more than 13 years until the end of its mission in September 2017.

For the last leg of its journey, Cassini was put on a particularly daring orbit passing between Saturn and its rings which brought it closer to Saturn than ever before. This allowed scientists to obtain images of Saturn’s ultraviolet auroras in unprecedented resolution.

The new observations are detailed in two new studies published in Geophysical Research Letters and JGR: Space Physics.

A new study shows drinking low-fat milk—both nonfat and 1% milk—is significantly associated with less aging in adults.

Research on 5,834 U.S. adults by Brigham Young University exercise science professor Larry Tucker, Ph.D., found people who drink low-fat milk experience several years less biological aging than those who drink high-fat (2% and whole) milk.

“It was surprising how strong the difference was,” Tucker said. “If you’re going to drink high-fat milk, you should be aware that doing so is predictive of or related to some significant consequences.”

In 2017, researchers believed they had found evidence for the elusive Majorana fermion. Now, a new study found that the exotic class of particles may still be confined to theory.

In the past two decades, scientists have also starting looking at art as a way to keep people mentally and physically healthy. In a report, the World Health Organization points to just how powerful art can be as a therapy. The report has problems but could lend heft and credibility to the field.

Security breach took place on January 7, but the city said it detected the intrusion in time to prevent any damage.

In a shift toward transparency, the National Security Agency announced a bug that could have left over 900 million PCs vulnerable to attack.
