GAVNet Collaborative Curation

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

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

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.

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.

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.

It is important to note that no single number or metric is robust enough to adequately describe the trajectory of the pandemic.
