Saturday's SpaceX launch will bring a fresh crew of astronauts to the International Space Station and kick off what are expected to be regular crewed SpaceX missions to orbit for NASA.

Subtropical Storm Theta formed in the Northeast Atlantic Monday night, becoming the 29th named storm of the 2020 hurricane season, the National Hurricane Center confirmed.

The World Meteorological Organization sets 21 alphabetical names for every season (excluding Q,U, X, Y and Z). This is the second time ever it's used all and had to turn to the Greek alphabet.
Editor's note: This article has been updated with further context on the hurricane season.
An independent panel of medical experts overwhelmingly said last week there is not enough evidence for the Food and Drug Administration to approve Biogen's experimental Alzheimer's drug, aducanumab.
