NewsCorals in Brazilian archipelago capture carbon equivalent to the burning of 324,000 liters of gasoline per year
A single species found in the Alcatrazes Archipelago, brain coral, produces around 170 tons of calcium carbonate annually. This represents the retention of approximately 20 tons of carbon in mineral form, which can last for centuries or millennia.

NewsStudies confirm influence of country of origin on trust in COVID-19 vaccines
During the pandemic, a preference for domestic vaccines or those from countries such as the United States, Germany, and the United Kingdom was observed for the first time. This phenomenon is known in marketing as the country of origin effect.

NewsStealth genetic switch in mosquitoes halts malaria spread
Biologists have created a CRISPR-based gene-editing system that changes a single molecule within mosquitoes, stopping the malaria-parasite transmission process. Genetically altered mosquitoes are still able to bite those with malaria, but the parasites can no longer be spread to other people.

NewsHow plants build the microbiome they need to survive in a tough environment
New research points to the idea that under some conditions plants can “curate” their microbiomes—selecting good microbes and suppressing harmful ones—to adapt to their environments.

NewsSilver nanoparticles produced by fungus could be used to prevent and treat COVID-19
Silver nanoparticles produced by the fungus Trichoderma reesei could become important allies in the prevention and treatment of COVID-19. Tests on hamsters showed that they not only inhibited the infection but also reduced the viral load in the lungs.
