A Brazilian startup has developed technology inspired by the soil mapping techniques used by the oil and gas industry to select drilling sites.

Brazilian researchers followed 38 COVID-19 patients and found that it took a month on average for the diagnostic test to become negative. In three patients, the virus remained detectable for more than 70 days.

The program can be used to control the quality of the data obtained, sequencing environmental samples by means of a technique known as metagenomics, which shows how complete the sequences mapped are, and whether they are contaminated by genetic material from other microorganisms.
