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…
A water-borne fungus that has led to the extinction of several species of amphibians that spend all or part of their life cycle in water…
Analysis of data collected over 20 years suggests the decline is due to the construction of over 180 dams on the Paraná basin and its…
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…
Researchers propose a method of magnetizing a material without applying an external magnetic field. The study shows that the phenomenon can be produced by means…
Fully occupied intensive care units (ICUs). Physically and mentally exhausted health workers. Chaotically overcrowded hospitals. These and similar problems posed by the COVID-19 pandemic in…
Researchers conducted the first large-scale survey of the microbiota present in the seamount’s ferromanganese crusts, describing bacteria and archaea involved in the nutrient cycle and…
A clinical trial was conducted with 240 patients who were given 200,000 IU of vitamin D3 on admission to hospital. The supplementation did not reduce…
Analysis of the first super slow motion recordings of upward flashes suggests a possible explanation for the formation of luminous structures after electrical discharges split…
The hormone acts as a barrier against SARS-CoV-2, blocking the expression of genes that encode proteins in cells serving as viral entry points, according to…
Food engineers in Brazil and France developed gels based on modified starch for use as “ink” to make foods and novel materials by additive manufacturing….
Monoclonal antibody tested by researchers at University of São Paulo and experimental drug given to patients in Italy by University of Pennsylvania research group promoted…
Model developed by Brazilian researchers predicts spatial and temporal evolution of epidemic diseases and can help plan more effective social isolation programs with less socio-economic…
Brazilian researchers discover that caecilians, limbless amphibians resembling worms or snakes that emerged some 150 million years before the latter, can probably inject venom…
Researchers isolated molecules present in the larvae of a blue light-emitting fungus gnat that inhabits the Appalachians; the study will help elucidate human diseases and…
The process occurs in active-core nuclei. A molecular gas cloud that accumulates in the central region is blown away by radiation from the black hole’s…
The lens can be used to produce high-resolution images with a wide field of view. It can serve as a camera lens in smartphones and…
