ACE2 is the protein used by new coronavirus (SARS-CoV-2) to enter the host-cells. Our comparative analysis with 70 mammals revealed a relatively high diversity of ACE2 between these species, but no polymorphism within human populations, at least considering 30 sites located at the ACE2 binding sites to the SARS-CoV-2. SARS-CoV-2 can infect any human from any population, but it is unable to infect, naturally and easily, other mammals, including pets. … Read More →
Will there be robot teachers?

Millet can be used as an economic alternative in cattle feed
Millet presents itself as an economically viable alternative to corn and sorghum, as a component of feed for cattle, under confinement. Researchers used the Monte Carlo simulation technique (economic risk analysis) to analyze the economic risks of this substitution. The results demonstrated a better economic viability when the level of substitution of corn grain for millet grain was total. … Read More →

Innovative method measures chlorophyll content in millet leaves
Responsible for the green color of plants, chlorophyll is an essential indicator in monitoring plant nutrients during their growth. Traditional methods for measuring chlorophyll, in addition to taking a long time, damage the leaves. Alternatively, a model based on hyperspectral images was developed to detect the chlorophyll content in millet leaves. … Read More →
