A report published in PLOS ONE describes key roles of various microorganisms in the development of the larvae of Scaptotrigona depilis. Researchers warn that this symbiotic relationship is threatened by the indiscriminate use of pesticides. A study published in PLOS ONE shows that the larvae of the Brazilian stingless beeScaptotrigona depilisdepend on interactions between three different species of fungus to complete their development and reach adulthood. The complex process of symbiosis was [...]

Differences in the molecular structures explain the different colors of this bioluminescence in different species. This discovery has the potential for new biotechnological applications, such as the imaging of muscles, blood and hemoglobin-rich tissue. One research group comprising Brazilian and Japanese scientists have discovered how luciferase produced by the railroad worm Phrixothrix hirtus emits red light. Luciferase is an enzyme that catalyzes the oxidation of [...]

Two new electric eel species have been identified in the Amazon basin, including one fish with a record-breaking shock, scientists say. Researchers had previously identified only one species of electric eel in more than 250 years of studying the creatures that lurk in South American waters and stun their prey with electric discharges. However, the new genetic and ecological analysis, published Tuesday in the peer-reviewed Nature Communications, identifies a total of three unique [...]

A new study has concluded that cannabidiol attenuates the aggressiveness induced by social isolation. The research, based on a mouse model, was performed by scientists at the University of São Paulo’s Ribeirão Preto Medical School (FMRP-USP) in Brazil. The results are published in the journal Progress in Neuro-Psychopharmacology and Biological Psychiatry. “Our study shows that cannabidiol can inhibit aggressiveness and that it does so by facilitating [...]
