“The hybrid model is probably among the worst that we could be putting forward if our goal is to stop the virus getting into schools,” says William Hanage, an epidemiologist at Harvard’s T.H. Chan School of Public Health.
Behnken and Hurley spent the next few hours drifting in orbit while NASA and SpaceX monitored weather conditions at the possible landing sites along the Florida coast.SpaceX mission control made the final decision to deorbit just an hour before Behnken and Hurley landed in the ocean.
I found it fitting that the first time Congress got to question the entire quartet of the most powerful tech CEOs, none were actually in the room.The distance didn’t just free them from the sweaty scrum of camera people, protesters, press tables, and face-to-face questioning from legislators enjoying the home-court advantage.

These neutrinos that Anita was searching for would be classified among the most energetic particles in the universe, which physicists believe are produced by the same processes that generate jets of charged particles called ultrahigh-energy cosmic rays.
That’s different from “presymptomatic” cases, in which people without symptoms test positive but later go on to show signs of illness.“There’s a lot of jargon out there and it’s even confusing to scientists,” says Ashleigh Tuite, an epidemiologist at the University of Toronto.
And the release of Android 11 is particularly focused on expanding privacy improvements to give you more control over what your apps can access and giving more ways to distribute software updates across Android's fragmented and disjointed device population.
“It may be years before academic research institutions reach a new normal,” the paper concludes.Scientists have redirected their energy toward fighting the novel coronavirus and have shared their data; already over 13,000 papers have been written on the topic, and over 3,000 preprints related to Covid-19 research have been shared on open-access preprint sites like bioRxiv and medRxiv.
Once SpaceX starts ferrying astronauts to orbit on operational missions, seats on Crew Dragon will cost roughly half the price of a seat on the Russian Soyuz capsule.

Thursday’s Soyuz launch will mark the end of the longest period in NASA’s history since it started crewed spaceflight that the agency didn’t have the capability to send its own astronauts to space.

But a few recent papers—two based on molecular biology, and one on rare, precious fossils from 1 billion years ago—are helping to fill in the gaps in our understanding of those ancient algae and what allowed them to eventually make the transition to land.
Instead of prioritizing physical barriers at all, especially at the southern border, researchers say that the US should be focused on limiting Covid-19 spread at ports of entry around the country through screening and home quarantine orders.
“Unless you’re really a super shooter,” says Vicki Stover Hertzberg, “gravity takes over.” Hertzberg, who studies how disease moves through planes at Emory University’s Rollins School of Public Health, says you can confine your wary looks to your immediate neighbors in your row, the one in front of you, and the one behind.
