As long as the coronavirus circulates widely, troublesome new mutations will chip away at the effectiveness of vaccines, and trigger fresh outbreaks with the accompanying lockdowns, travels restrictions and calls for social distancing and mask-wearing through 2021 and 2022.
With variants and big outbreaks in India and elsewhere, the pandemic won't end until poor nations as well as rich ones are vaccinated.
"Morally compromised"? The cells from aborted human embryos were crucial in developing and testing the Moderna, Pfizer and Johnson & Johnson vaccines. That puts the Catholic Church in a difficult spot.
The WHO team's press briefing, with its dismissal of the lab-leak hypothesis, failed to persuade U.S. officials and did nothing to bridge the divide between China and the West.
Will we wake up one day and find that China has been reading our mail? Losing our technological edge could have major security implications for the U.S.
More than four in 10 Americans say they won't get the COVID vaccine when it becomes available. Big problem: Even a highly effective vaccine won't do much to rein in the pandemic if enough people can't be persuaded to get the shot.
Americans want a COVID-19 vaccine—but worry that it could be rushed out before the election. Here's what the science says.
In a Newsweek interview, Fauci says a presidential edict to force the FDA to approve an expedited COVID-19 vaccine before Election Day would never fly.
"This virus is going to continue to spread by the force of what I call viral gravity," says Michael Osterholm. "It's biology, chemistry and physics. No policy decisions are going to keep it from happening."
The point of contact tracing is to extinguish small pockets of new cases before they explode into big outbreaks like the ones that steamrolled New York City and New Orleans last month.
Biomedical research ultimately helps protect public health, Dr. Fauci argued in explaining his support for controversial research.
After reporting that Covid-19 occurred naturally, U.S. intelligence modified its stance to say it might have leaked from a lab.
The computer analysis showed that as restrictions loosen, the coronavirus will make a comeback; social distancing rules would have to go into effect a second time.. and a third, and so on. And it might not even work.
The criticism may heighten tensions between Trump, who has touted the drug, and Dr. Fauci and other experts, but is unlikely to affect coronavirus treatment in the short term.
There's no agreement about what factors to consider. Alabama guidelines would exclude patients with severe mental retardation. New York policy is to maximize the number of lives saved—meaning a 90-year-old patient would get the same priority as a 20-year-old.
Deciding to lift the lockdown is difficult because very little is known about the COVID-19 virus and testing is woefully inadequate in the U.S. But the longer the disruption goes on, the more difficult it will be for the economy to recover..
Recent climate-change projections have put some new cities in the crosshairs
Tehran could cause significant disruption with cyber attacks against the U.S. government, companies, high-profile individuals—and possibly even the 2020 elections.
Listening to Jimmy Wales speak is a bit like reading a Wikipedia page: Sound bites are few, but the tone is fair and measured.
As the cost of "sequencing" DNA has dropped, more and more patients are undergoing genetic testing. How will the medical industry use that data to further research and clinical practice while preserving the privacy of patients? David Yizhar, the founder and CEO of Israeli startup Geneyx, thinks blockchain technology could offer a solution.
The frequency of more potent storms is growing, but the storms are also slowing down in speed, inundating the ground below.
Scott Sheppard's team is using a supercomputer to simulate 79 discovered moons of Jupiter over billions of years to learn how often Valetudo would collide with its neighbors.
