C.D.C. Employees Ask Agency to Address ‘Racism and Discrimination’

By Kristie J. Fields 2 hours ago

More than 1,000 employees of the Centers for Disease Control and Prevention have signed a letter calling for the agency to address “a pervasive and toxic culture of racial aggressions, bullying and marginalization” against Black employees.

The letter, a copy of which was obtained by The New York Times, was first reported by National Public Radio on Monday. It was sent to Dr. Robert R. Redfield, the director of the C.D.C., on June 30.

“After decades of well-meaning, yet underfunded, diversity and inclusion efforts, we have seen scant progress in addressing the very real challenges Black employees experience at C.D.C.,” the letter said, pointing to a “lack of inclusion in the agency’s senior ranks” and “ongoing and recurring acts of racism and discrimination.”

The letter comes as the C.D.C. is confronting the most urgent public health emergency in its 74-year history. The federal response to the coronavirus pandemic has been

In Astounding Test, Scientists Revive Damaged Lungs for Transplant

With this method, they have successfully revived and transplanted 600 lungs in the past decade, said Dr. Marcelo Cypel, a lung transplant surgeon at the University of Toronto. But there are limitations: Lungs can be maintained this way only for hours, not days. And few lungs can be rescued.

“If you have more time, you have more time to repair the injuries,” Dr. Cypel said. “You can’t reverse a pneumonia in just four or six hours. But if you keep the lung for a few days, you can.”

So Dr. Vunjak-Novakovic and her group decided that instead of making new lungs, they might improve on this method. It was becoming clear that, to recover, lungs needed not just a ventilator but also body — to remove metabolic wastes, and to deliver the energy needed keep the organ alive and restore it to health.

The solution? A pig to support the

How to Reopen Schools: What Science and Other Countries Teach Us

By Kristie J. Fields 3 hours ago

In one community in northern France, Crépy-en-Valois, two high school teachers became ill with Covid-19 in early February, before schools closed. Scientists from the Institut Pasteur later tested the school’s students and staff for coronavirus antibodies. They found antibodies in 38 percent of the students, 43 percent of the teachers, and 59 percent of other school staff, said Dr. Arnaud Fontanet, an epidemiologist at the institute who led the study and is a member of a committee advising the French government.

“Clearly you know that the virus circulated in the high school,” Dr. Fontanet said.

Later, the team tested students and staff from six elementary schools in the community. The closure of schools in mid-February provided an opportunity to see if younger children had become infected when schools were in session, the point when the virus struck high school students.

Researchers found antibodies in only 9 percent of elementary students,

“There’s no downside to wearing a mask,” Admiral Giroir responded. “I’m a pediatric I.C.U. physician. I wore a mask 10 hours a day for many many years.”

Dr. Adams wore a mask during his entire interview on the CBS program “Face the Nation” even though he was being interviewed remotely from Indiana. He said measures like wearing face coverings were “critically important.”

Earlier in the pandemic, Dr. Adams had discouraged people from buying masks, in part so there would be enough for medical workers, and he had said “masks do not work for the general public in preventing them from getting coronavirus.”

On Sunday, when the host of “Face the Nation,” Margaret Brennan, asked if he regretted saying that masks were not effective in keeping the general population healthy, Dr. Adams replied: “Once upon a time, we prescribed cigarettes for asthmatics, and leeches and cocaine and heroin for people as
