Finally, a better use for dog sniffing

Yes, please. Much better than sniffing for marijuana.

The Dogs Training to Sniff Out COVID-19

Promising early results from several studies have encouraged researchers around the world to develop and expand canine programs that may screen people for COVID-19 infection at places like airports, hospitals, or sports venues.

    How do they do it? Dogs have “125-300 million olfactory cells and a third of their brains [are] devoted to interpreting odors…to sniff out the volatile organic compounds” of COVID-19 infections.

    Another reason not to throw people into some county lockup, even for a short period of time, for merely possessing or using drugs, cannabis, psychedelics, etc:

    23-FEB-2021 – Unique analysis of US county-level data finds a strong association between jail incarceration and death rates at the county level from infectious diseases, chronic lower respiratory disease, drug use, and suicide; and to a lesser extent heart disease and cancer.

    Findings underscore public health benefits of reducing jail incarceration and importance of interventions to mitigate the harmful effects of mass imprisonment on community health including treatment for substance use disorder and greater investment in social services. […]

    A new study puts to rest another fear about marijuana legalization and women who are pregnant:

    Question: Is there an association between recreational cannabis legalization and prevalence of maternal cannabis use during the preconception, prenatal, and postpartum periods?

    Findings: In this cross-sectional study of 73,551 women, cannabis use increased significantly among women before pregnancy and after pregnancy but not during pregnancy in states that had legalized recreational cannabis compared with states that had not legalized cannabis.

    New technology from MIT et al. uses optical sensing to monitor stress in plants, allowing the grower to detect a problem before it causes a loss of yield:

    …Researchers from the Disruptive & Sustainable Technologies for Agricultural Precision (DiSTAP) Interdisciplinary Research Group (IRG) of Singapore-MIT Alliance for Research and Technology (SMART), MIT’s research enterprise in Singapore and Temasek Life Sciences Laboratory (TLL) have designed a portable optical sensor that can monitor whether a plant is under stress. The device offers farmers and plant scientists a new tool for early diagnosis and real-time monitoring of plant health in field conditions.

    Precision agriculture is an important strategy for tackling growing food insecurity through sustainable farming practices, but it requires new technologies for rapid diagnosis of plant stresses before the onset of visible symptoms and subsequent yield loss. SMART’s new portable Raman leaf-clip sensor is a useful tool in precision agriculture allowing early diagnosis of nitrogen deficiency in plants, which can be linked to premature leaf deterioration and loss of yield.
