Frequent, rapid testing could turn national COVID-19 tide within weeks
What we learned:
- Researchers used mathematical modeling to predict whether frequency, turnaround time or sensitivity of diagnostic tests matter most in curbing the spread of COVID-19.
- Tests with swift, same-day turnaround reduced spread significantly more than much more sensitive clinical tests, which took longer to return results.
- The authors say frequent, rapid tests could be used as 鈥減ersonalized stay-at-home orders,鈥� which could 鈥渄rive the epidemic toward extinction within six weeks鈥澨齱ithout shutting down schools and businesses.
Museum spotlights reptiles and amphibians in incredible detail
What we learned:
- A new project at the 抖阴短视频 Museum of Natural History will collect high-resolution 2D and 3D photos of roughly 1,100 specimens of reptiles and amphibians from its collections.
- The effort, called OMeso, will focus on animals from Mesoamerica, which boasts some of the most diverse assemblages of reptiles and amphibians in the world.
- The images may help scientists to protect endangered species, providing them with new tools to track how the ranges of vanishing animals have shifted over time.
Parental restrictions on childhood tech use have few lasting effects
What we learned:
- Researchers analyzed survey data on technology use from 1,200 participants, following the same people from adolescence to young adulthood.
- Parental restrictions on adolescent use had no lasting effect on young adult use. Time spent with technology during youth had very little effect on adult use. Lasting tech 鈥渁ddiction鈥� does not appear to be widespread.听
- Amid the global pandemic, parents are less worried about kids鈥櫶齮echnology use than in the past.
