Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: A study aiming at the development of a dengue vaccine shows that the prevalence of a virus lineage upon the other does not rely on the highest replication rate: it is rather based on the virus' ability in triggering weaker activation of the patient's immune response. A lineage of type 1 dengue virus found in Brazil is able to prevail over another even though it multiplies less in vector mosquitoes and infected human [...]

Summary: Timber harvested illegally under fraudulent permits is undercutting conservation efforts in the Brazilian Amazon, new research by an international collaboration shows. Share: FULL STORY Timber harvested illegally under fraudulent permits is undercutting conservation efforts in the Brazilian Amazon, new research by an international collaboration shows. advertisement The findings represent a troublesome counterpunch to an overall decline in deforestation rates in the region and [...]

Date: August 6, 2018 Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: Experiments with rats show that intrauterine protein restriction induces sex hormone imbalance, which appears to favor development of cancer in old age. The rate of prostate tumor development reached 50 percent among the old rats submitted to low-protein diet during pregnancy and lactation alike. The offspring of females fed a low-protein diet during pregnancy and lactation are significantly [...]

Date: August 3, 2018 Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: Researchers have developed a sugarcane line with the ScGAI gene expression silenced. The modification resulted in an adequate phenotype for use in 2G ethanol production, featuring a bigger culm and more biomass. Despite international breeding efforts, advanced agronomy and effective management of pests and diseases, sugarcane yields have been static for decades owing to constraints on culm [...]

Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: Researchers have used an editing tool to investigate a gene that plays a key role in eliminating autoaggressive cells and controlling the development of diseases such as type 1 diabetes. In tests with mice, the disrupting of medullary thymic epithelial cells gene impaired the processing of mRNA involved in their adhesion to autoaggressive T lymphocytes.

Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: Results point to potential targets worth exploring in effort to halt infection by the emerging virus, which is transmitted by the C. paraensis midge. Oropouche's strategy of 'hijacking' the Golgi complex in order to replicate itself has never been described before, state the researchers. Share: FULL STORY The strategy used by the Oropouche virus to replicate in human cells has been described for the first time by researchers [...]

Ancient people in the region began cultivating plants and altering forests earlier than previously thought

Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: Scientists have obtained from hematite a new material with application as a photocatalyst, christened 'hematene.' The three-atom thick hematene is a ferromagnetic material, as opposed to the iron ore from which it was created. Share: FULL STORY Following the isolation of graphene in 2004, a race began to synthesize new two-dimensional materials. 2D materials are single-layer substances with a thickness of between one atom [...]

Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: For the first time, scientists reconstruct the rainfall distribution in Brazil during the climate changes that marked the Middle Ages using isotopic records from caves. Share: FULL STORY A new study published in Geophysical Research Journal shows that the so-called Little Ice Age -- a period stretching from 1500 to 1850 in which mean temperatures in the northern hemisphere were considerably lower than at present -- exerted [...]
