Authorities are closing honky tonks, bars and other drinking establishments in some parts of the U.S. to stem the surge of COVID-19 infections — a move backed by sound science about risk factors that go beyond wearing or not wearing masks. In the words of one study, it comes down to the danger of “heavy breathing in close proximity."
Dozens of scientists doing research funded by Mark Zuckerberg say Facebook should not be letting President Donald Trump use the social media platform to “spread both misinformation and incendiary statements.” The researchers, including 60 professors at leading U.S. research institutions, wrote the Facebook CEO on Saturday asking Zuckerberg to “consider stricter policies on misinformation and incendiary language that harms people," especially during the current turmoil over racial injustice.
SpaceX delivered two astronauts to the International Space Station for NASA on Sunday, following up a historic liftoff with an equally smooth docking in yet another first for Elon Musk’s company. With test pilots Doug Hurley and Bob Behnken poised to take over manual control if necessary, the SpaceX Dragon capsule pulled up to the station and docked automatically, no assistance needed.
A rocket ship built by Elon Musk's SpaceX company thundered away from Earth with two Americans on Saturday, ushering in a new era in commercial space travel and putting the United States back in the business of launching astronauts into orbit from home soil for the first time in nearly a decade. NASA's Doug Hurley and Bob Behnken rode skyward aboard a white-and-black, bullet-shaped Dragon capsule on top of a Falcon 9 rocket, lifting off at 3:22 p.m. from the same launch pad used to send Apollo crews to the moon a half-century ago.
It’s not quite a case of coitus interruptus, but efforts to create a very special baby are definitely on hold. Blame the pandemic. Groundbreaking work to keep alive the nearly extinct northern white rhino subspecies — population, two — by in-vitro fertilization has been stalled by travel restrictions. And time is running out. The two northern white rhinos are female. The goal is to create viable embryos in a lab by inseminating their eggs with frozen sperm from dead males, then transfer them into a surrogate mother, a more common southern white rhino.
As President Donald Trump pushes to reopen the country despite warnings from doctors about the consequences of moving too quickly during the coronavirus crisis, he has been lashing out at scientists whose conclusions he doesn't like. Twice this week, Trump has not only dismissed the findings of studies, but suggested — without evidence — that their authors were motivated by politics and out to undermine his efforts to roll back coronavirus restrictions.
The two astronauts who will end a nine-year launch drought for NASA arrived at Kennedy Space Center on Wednesday, exactly one week before their historic SpaceX flight. It will be the first time a private company, rather than a national government, sends astronauts into orbit.
NASA's chief of human exploration has resigned just days before the first astronaut launch in nearly a decade from Kennedy Space Center. Douglas Loverro, whose resignation took effect Monday, joined NASA last October.
The European Space Agency said Friday that human urine could one day become a useful ingredient in making concrete to build on the moon. The agency said researchers in a recent study it sponsored found that urea, the main organic compound in urine, would make the mixture for a “lunar concrete” more malleable before it hardens into its sturdy final form.
Meet your new but shy galactic neighbor: A black hole left over from the death of a fleeting young star. European astronomers have found the closest black hole to Earth yet, so near that the two stars dancing with it can be seen by the naked eye.
