Using DNA from two ancient humans unearthed in two different archaeological sites in northeast Brazil, researchers have unraveled the deep demographic history of South America at the regional level with some surprising results. Not only do they provide new genetic evidence supporting existing archaeological data of the north-to-south migration toward South America, they also have discovered migrations in the opposite direction along the Atlantic coast – for the first time. Among the key findings, they also have discovered evidence of Neanderthal ancestry within the genomes of ancient individuals from South America. Neanderthals ranged across Eurasia during the Lower and Middle Paleolithic. The Americas were the last continent to be inhabited by humans.

More than 50 million people have epilepsy; about 80% live in lower- or middle-income countries, where diagnosis and treatment can be difficult or impossible. The percentage of people with epilepsy that is not receiving treatment is known as the treatment gap; in some countries, this gap exceeds 90%.
Genomic research helps explain why some people with a common TP53 mutation widespread in Brazil get cancer while others do not.

A simple screening test could help identify infants at risk of fetal alcohol spectrum disorders (FASD), according to a report in the journal Alcoholism: Clinical and Experimental Research. Prenatal exposure to alcohol can cause a wide range of lifelong physical, behavioral, and cognitive disabilities, encompassed by the umbrella term FASD. Identifying babies at risk for FASD has previously relied on maternal self-reports of drinking in pregnancy; however, this can be unreliable, as women may under-report their drinking because of recall bias or fear of stigma. Recently, biological markers have been identified that can provide more objective data on prenatal alcohol exposure and supplement information from maternal self-reports. One such biomarker, phosphatidylethanol (PEth), is a direct marker of alcohol metabolism that can indicate exposure with a high level of accuracy, and can be simply measured in newborns (and their mothers) using minimally invasive methods.
Study suggests that TV appearances by Bolsonaro led to millions more Brazilians ignoring social distancing in the days following broadcast.
