In a study involving mice, scientists used a technique that combines light stimulation and bioengineering to activate a cluster of nerve cells deep inside the brain. The discovery could pave the way to future treatment of eating disorders.

Researchers detected SARS-CoV-2 in male reproductive cells under the microscope even when PCR testing failed to detect the virus in semen. The discovery serves as a warning of possible implications for natural conception and particularly for assisted reproduction.

Scientists at São Paulo State University (UNESP) and Oklahoma State University (OSU) verified in the field that a parasitoid wasp that neutralizes the Brown stink bug should ideally be released at intervals of 30 m.

In experiments with mice, researchers at the State University of Campinas (UNICAMP) in Brazil and the Pasteur Institute in Lille (France) found that viral load and inflammation decreased in animals infected by influenza virus when they were given the substance.

A study conducted by researchers from the D'Or Institute for Research and Education (IDOR) and the Rede D'Or Pathological Anatomy in conjunction with several North American institutions, including the National Cancer Institute (NIH), used new molecular analyses to unravel the biological mechanisms of pediatric brain tumors and refine their classification. The research results were recently published in the journal Acta Neuropathologica Communications.A study conducted by researchers from the D'Or Institute for Research and Education (IDOR) and the Rede D'Or Pathological Anatomy in conjunction with several North American institutions, including the National Cancer Institute (NIH), used new molecular analyses to unravel the biological mechanisms of pediatric brain tumors and refine their classification.

An article on the study describes the preparation of films comprising polyaniline nanostructures with an underlayer of multi-walled carbon nanotubes and assesses their performance in photoelectrocatalysis, especially to obtain hydrogen.
