The Nationals and Yankees knelt in unison before the first game of the baseball season as part of an opening day ceremony Thursday night that featured references to the Black Lives Matter movement, the coronavirus pandemic — including an off-the-mark first pitch by Dr. Anthony Fauci — and the home team’s 2019 championship.

US hits 1,000 coronavirus deaths for second straight day, hospitalizations approach record | TheHill

The Johns Hopkins University data dashboard reported 1,195 U.S. coronavirus-related deaths Wednesday, the second consecutive day with more than a thousand fatalities. Meanwhile, the Covid Tracking Project showed nearly 60,000 people are hospitalized with the virus across the country, marking a continue rise from the end of June.

Hospitalizations are only about 200 short of the peak from April.

Senate Approves Proposal To Strip Confederate Names From Army Bases By Veto-Proof Majority

The Senate overwhelmingly approved a defense bill on Thursday that included Sen. Elizabeth Warren’s (D-MA) provision requiring the military to rename U.S. bases  named after Confederate generals.

The bill passed by a vote of 86-14, a veto-proof majority that would override President Donald Trump’s effort to kill the measure, which he had threatened to do at the end of June after Warren announced her proposal.

Scientists Want To Know More About Using UV Light to Fight COVID-19 Spread – Note

To demonstrate the concept, Davidson lit a cigar inside Marlaina’s and showed how the smoke danced upward, collecting in the ceiling space with the UV fixtures.

“If somebody has undetected coronavirus and doesn’t eat with a mask and is talking and so on, the vast majority of their particles are going to get pulled up there into the killing zone and circulate and bounce around,” Davidson said. “Statistically, the risk to other people is going to be very low.”

Research shows close to 90% of airborne particles from a previous coronavirus (SARS-CoV-1) can be inactivated in about 16 seconds when exposed to the same strength of UV as in the restaurant’s ceiling. Other viruses, such as the adenovirus, are more resistant and require a higher dose of UV.

“Although it’s not perfect, it probably offers the best solution for direct air disinfection” in the current pandemic, said David Sliney, a faculty member at Johns Hopkins University and longtime researcher on germicidal UV.

When used with proper ventilation, upper-room GUV is about 80% effective against the spread of airborne tuberculosis, according to several studies. This is equivalent to replacing the air in a room up to 24 times an hour.

So, even if there is upper-room UV in a building, Corsi said, face masks and social distancing are still necessary to block larger respiratory droplets and remove some of the aerosols in the near field. But Corsi said there’s now enough evidence to show that coronavirus aerosols can hang in the air and spread throughout a room (“the far field”), and it’s time to take that airborne spread seriously.
