The insect moves droplet of saliva in and out of its mouth to promote evaporation and lower body temperature, according to study by researchers in Brazil.

The study focused three fungi species which produce enzymes with application in biomass degradation; scientists in Brazil reveal how these substances are regulated and how they can interact synergically.

A research with ant from genus Atta reveals that a bacteria in their microbiota plays a key role in communication among individuals and also on the colony's defense against pathogens. A Brazilian group of scientists also showed how a type of fungus participates on stingless bees' development cycle.

A study of the Inka origins and their lineages was performed in twelve contemporary families with presumed patrilineal lineage to Inka monarchs. A comparison of Y-chromosome and mtDNA markers of these descendants with a database of about 2400 South American native individuals of Peru, Bolivia, Brasil and Ecuador showed two distinct patrilineal clusters, and a very diverse matrilineal origin. In addition they show great affinity to areas South of Cusco including the Lake Titicaca.

A particle that is its own anti-particle is the subject of a theoretical study by Brazilian researchers with results published in Scientific Reports. These Majorana quasi-particles can emerge as excitations in topological superconductors.
