Peer-Reviewed Publication

Computer simulations suggested that plankton communities at the poles will be particularly badly damaged by the rise in temperature, while in temperate zones they will suffer from a reduced flow of nutrients and in the tropics from increased salinity.

Engineering drought-resistant plants may be more difficult than it seems

Smithsonian Tropical Research Institute
Peer-Reviewed Publication

The adaptation of certain plants to drought and high temperatures involves a fundamental reprogramming of their metabolism, not just a simple adjustment that can be made by regular plants.

Study: COVID-19 affects transplant recipients differently, possible therapeutic approach suggested

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

Liver recipients who contracted SARS-CoV-2 recovered faster and with less inflammation than heart or kidney recipients, according to researchers at the University of São Paulo. The reason may have to do with differing amounts and types of immunosuppressants, the drugs used to prevent organ rejection

In Brazilian Amazon, savannization and climate change will expose 12 million to lethal heat stress

Fiocruz Piauí
Peer-Reviewed Publication

A landmark study examining extreme impacts of forest loss on human health finds a threshold for human survival. By 2100, roughly 12 million Brazilians may be exposed to extreme risk of heat stress and vulnerable populations could be most severely impacted.

Peer-Reviewed Publication

Loss of ACE2, the protein used by the novel coronavirus to invade human cells, leads to an imbalance in systems that regulate essential metabolic functions, impairing blood filtration and causing kidney injuries that can become permanent

Study maps immune system genes involved in resistance to SARS-CoV-2

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

The researchers analyzed genetic material from 86 discordant couples in the sense that only the wife or husband was infected by SARS-CoV-2 although both were exposed to the virus. The results suggest that certain genetic variants found more frequently in the resistant subjects are associated with more efficient activation of defense cells known as natural killers (NKs).
