CDC promotes Vermont testing program On the 8th of May, the Vermont Department of Health instituted a policy whereby those who had been exposed to COVID-19 who were in quarantine could leave early if they tested negative after 7 days. A study conducted by the CDC found that this method was effective at catching COVID-19 among asymptomatic people in quarantine, while also allowing people who were not infected to get back to their normal lives sooner. They suggested that other states should consider this policy. New Technology for Monitoring Bird Populations Gathering specific data on bird populations can be difficult, since their rapid movement and ability to hide in foliage make consistent observation impossible. A newly developed technology called an acoustic recording unit uses algorithms to detect different birdsongs. This technology was recently tested in the Marsh-Billings-Rockefeller National Historic Park in Vermont, to examine the presence of the Eastern Wood-Pewee (Contopus virens). The device was able to provide significantly more accurate data.
