Aerosol transmission of viruses must be acknowledged as a key factor leading to the spread of infectious respiratory diseases. Evidence suggests that SARS-CoV-2 is silently spreading in aerosols exhaled by highly contagious infected individuals with no symptoms. Owing to their smaller size, aerosols may lead to higher severity of COVID-19 because virus-containing aerosols penetrate more deeply into the lungs (10). It is essential that control measures be introduced to reduce aerosol transmission. A multidisciplinary approach is needed to address a wide range of factors that lead to the production and airborne transmission of respiratory viruses, including the minimum virus titer required to cause COVID-19; viral load emitted as a function of droplet size before, during, and after infection; viability of the virus indoors and outdoors; mechanisms of transmission; airborne concentrations; and spatial patterns. More studies of the filtering efficiency of different types of masks are also needed. COVID-19 has inspired research that is already leading to a better understanding of the importance of airborne transmission of respiratory disease.

With this in mind, a growing chorus has called for broader sealing (also called "expungement") of criminal records. Sealing an official criminal record hides it from view by employers, landlords, and others doing formal background checks. However, relatively few criminal records are currently eligible for sealing (typically minor offenses committed a long time ago), and the process to have a record sealed is complicated and costly. Advocates are pushing to expand the set of records eligible for sealing-and to leverage technology to make sealing automatic. These are often referred to as 'Clean Slate' policies.

Like other scientists and public health experts, we have argued that more asymptomatic people, not fewer, need to be tested to bring the pandemic under control. Now, in the face of a dysfunctional C.D.C., it's up to states, other institutions and individuals to act.

Recent major surveys show that reductions in genomic complexity - including the loss of key genes - have successfully shaped the evolution of life throughout history.

Researchers have resolved a longstanding biological debate by revealing the existence and function of complex RNA structures in plants.

Simulating an earthquake on a miniature scale in a laboratory known unofficially as the "seismological wind tunnel," engineers and seismologists have produced the most comprehensive look to date at the complex physics of friction driving destructive thrust-fault earthquakes.

Ehre, a member of the UNC Marsico Lung Institute and the UNC Children's Research Institute, captured these images to illustrate how intense the SARS-CoV-2 infection of the airways can be in very graphic and easily understood images. Her lab conducted this research in collaboration with the labs of Ralph Baric, Ph.D., the William R. Kenan Distinguished Professor of Epidemiology at the UNC Gillings School of Public Health, who holds a joint faculty appointment at the UNC Department of Microbiology and Immunology, and Richard Boucher, MD, the James C. Moeser Eminent Distinguished Professor of Medicine and Director of the Marsico Lung Institute at the UNC School of Medicine Covid-19

If Democrats get their wish-a landslide victory leading to a Joe Biden presidency, as well as a Democratic Senate and House-they will face an immediate challenge to getting things done. No matter the size of that landslide, the Republican response will be undeterred: a united opposition, akin to a parliamentary minority party, blocking what they can and delegitimizing what they cannot. It will be little different from their approach in the aftermath of the 2008 Democratic landslide. That formula led to huge GOP gains in the 2010 midterm election, and, after Barack Obama's big reelection victory in 2012, even more gains in the 2014 midterms.

Viral immunologists say that results so far have been predictable - here's why that's good news.
