Over 80% of Atlantic Rainforest remnants have been impacted by human activity
Publicado em 24 fevereiro 2021
A Brazilian study published in Nature Communications shows that human activities have directly or indirectly caused biodiversity and biomass losses in over 80% of the remaining Atlantic Rainforest fragments.
According to the authors, in terms of carbon storage, the biomass erosion corresponds to the destruction of 70,000 square kilometers (km²) of forest—almost 10 million soccer pitches—or USD 2.3 billion-USD 2.6 billion in carbon credits. "These figures [...]

Models to predict dengue, Zika and yellow fever outbreaks developed by researchers
Publicado em 24 fevereiro 2021Yellow fever was the first human disease to have a licensed vaccine and has long been considered important to understanding how epidemics break out and should be combated. It was introduced to the Americas in the 17th century, and high death rates have resulted from successive outbreaks since then. Epidemics of yellow fever were associated with the slave trade, the U.S. gold rush and settlement of the Old West, the Haitian Revolution, and construction of the Panama Canal, to cite only a few [...]Medical Xpress (Reino Unido) -

Models to predict dengue, zika and yellow fever outbreaks are developed by researchers
Publicado em 23 fevereiro 2021Scientists will monitor areas in which these diseases are endemic, such as São Paulo, the Amazon, the Pantanal and Panama, to investigate the factors that trigger outbreaks (monkey being examined in Manaus área.

Neanderthal Brain Organoids Show How a Single Gene Alteration May Have Separated Modern Humans From Predecessors
Publicado em 19 fevereiro 2021Novel study used brain organoids genetically modified to mimic now-extinct Neanderthals. As a professor of pediatrics and cellular and molecular medicine at University of California San Diego School of Medicine, Alysson R. Muotri, PhD, has long studied how the brain develops and what goes wrong in neurological disorders. For almost as long, he has also been curious about the evolution of the human brain — what changed that makes us so different from preceding Neanderthals and [...]Brinkwire (Reino Unido) -
South American lizard’s blood pressure mechanism is more efficient at cool temperatures
Publicado em 18 fevereiro 2021The mechanism that keeps arterial blood pressure stable in black and white tegu lizards (Salvator merianae) even as their body temperature varies substantially is more efficient at lower than higher external temperatures, contrary to what has always been believed, and vascular regulation plays a key role in pressure adjustments, according to an article published in PLOS ONE by researchers at the Federal University of São Carlos (UFSCar) in the state of São Paulo, Brazil.

Application of potassium to grass used as cover crop guarantees higher-quality cotton
Publicado em 16 fevereiro 2021The use of cover crops between cotton harvests protects the soil, conserves water, and reduces the risk of erosion. Researchers at the University of Western São Paulo (UNOESTE) and São Paulo State University (UNESP) in Brazil found that application of potassium (K) to a grass cover crop grown before cotton in sandy soil lowered production cost and resulted in cotton with a higher market value. "The dynamics of early application of potassium to grass planted as [...]Phys.Org (Reino Unido)
