FDA APPROVES POWERFUL HIV DRUG THAT NEARLY ELIMINATED SPREAD IN CLINICAL TRIALS

The US Food and Drug Administration has approved a new HIV-prevention medication called Yeztugo. The drug nearly eliminated the spread of HIV in clinical trials. It is the first in a new class of antiretrovirals that block HIV from infecting and making new copies of itself inside the immune cells it targets. It costs $14,109 per injection, so health insurers will likely decline to cover the treatment in favor of other forms of PrEP, which can cost as little as $30 per month.

SPACEX'S NEXT STARSHIP JUST BLEW UP ON ITS TEST STAND IN SOUTH TEXAS

SpaceX had set June 29 as a tentative launch date for the next Starship test flight, but that won't happen now. The extent of the damage at the site is unclear, so it is unknown how long the test site will be out of commission. Videos of the explosion are available in the article.
