medicalxpress.com An article published in npj Aging reveals that natural production of auto-antibodies increases with age, and that infection by SARS-CoV-2 can exacerbate production of auto-antibodies relating to auto-immune diseases, helping to explain why aging increases the chances of developing severe COVID-19. The study also discovered some of the factors that associate the severe form of the disease with blood clotting disorders such as thrombosis. "These [...]

theguardian.comAbrir The first half of Jair Bolsonaro’s presidency was so destructive for the Amazon that it was comparable to the record 2016 El Niño drought and heatwave in terms of carbon emissions, according to scientists.

We further tested the presence of differential affinity of ancient Brazilian individuals to present-day Papuans, Onge and Australians, as well as the 40,000-year-old Tianyuan genome-wide data from China77 using f4 statistics of the form f4(Mbuti, Papuan/Onge/Australian/Tianyuan; Ancient Brazilian A, Ancient Brazilian B). Only the JabuticabeiraII_~2400BP group reaches significant attraction to both Onge and Papuans, and only in comparison to LapaDoSanto_9600BP (ref. 63). This suggests either [...]
