Researchers discovered new compounds in marine sponges that were capable of killing antibiotic-resistant bacteria. Brazilian scientists discovered several compounds in a marine sponge from Fernando de Noronha, an island off the coast of the Northeast, that killed antibiotic-resistant bacteria. Researchers at the University of So Paulo (USP) in So Carlos, Brazil, have identified a variety of bioactive substances in a marine sponge that was found on Fernando de Noronha, an island located [...]

Cold Exposure Activates Brown Adipose Tissue To Produce Anti-Inflammatory Molecules

Brazilian researchers discovered, characterized, and validated the functions of two novel enzyme families with biotechnological potential. One method of reducing reliance on oil and other fossil fuels is to convert agroindustrial waste into molecules of societal relevance, such as biofuels and biochemicals. Brazil is well-positioned to lead this shift as one of the world’s major producers of plant biomass, but lignocellulosic raw materials (containing lignin, hemicellulose, and [...]

University of California San Diego (UCSD) study uses lab-grown human brain tissue to identify neural abnormalities in Pitt-Hopkins Syndrome and test gene therapy tools. In a study published on May 02, 2022, in the journal Nature Communications, scientists at the University of California San Diego School of Medicine used human brain organoids to discover how a genetic mutation associated with a severe form of autism disrupts neural development. Using gene therapy tools to recover the [...]

The study could serve as the basis for novel strategies to ensure that future generations are not affected by such diseases. Existing treatments are palliative, aimed at improving quality of life for the patient or delaying progression of the disease. A research article published in the journal Science Advances describes a mechanism that helps explain how certain kinds of genetic disorders known as mitochondrial diseases are transmitted from mother to child. The study it reports could serve [...]

Research conducted at the University of Campinas in Brazil was driven by observations of fluctuations in autoluminescence caused by seed germination in cycles regulated by gravitational tides. The rhythms of activity in all biological organisms, both plants and animals, are closely linked to the gravitational tides created by the orbital mechanics of the Sun-Earth-Moon system. This truth has been somewhat neglected by scientific research but is foregrounded in a study by Cristiano de Mello [...]

Worldwide, millions of people follow vegan and vegetarian diets for religious, ethical, environmental, or economic reasons. While these diets have purported health benefits, they can also lack essential nutrients, such as vitamins B 12 and D 3, if not well-planned or supplemented correctly. Now, researchers reporting in ACS Food Science & Technology have packed a strawberry-flavored gummy with these vitamins, formulating it without any animal products so vegans and vegetarians can reach [...]

Research conducted in Brazil for more than 20 years in the Paraná River basin shows a drastic fall in the number of aquatic insects in the region, which is considered well-preserved and distant from the negative impacts of agriculture, cattle breeding, and urbanization. The fieldwork was done by researchers affiliated with the State University of Maringá’s Center for Research in Limnology, Ichthyology and Aquaculture (NUPELIA-UEM). The data was systematized byGustavo [...]

In an article published in PNAS, researchers affiliated with Butantan Institute describe the genome of Bothrops jararaca and suggest the origin of genes responsible for toxins in its venom. A group led by researchers at Butantan Institute and funded by São Paulo Research Foundation — FAPESP has completed the first sequencing of a Brazilian snake’s genome. The study is reported in an article published in the journal PNAS. It suggests that the nine genes that encode [...]
