NewsAntibiotic resistance: Towards drugs to disarm bacteria
Researchers have identified the mutation frequency decline (Mfd) protein, a virulence factor produced by all bacteria and essential for them to resist the host immune system. This protein has the additional function of promoting spontaneous and random mutations.

NewsToxic chemical pollutants detected in lichens and mosses in the Irati forest
Scientists used a species of lichen (Parmelia sulcata) and a species of moss (Hypnum cupressiforme) from Irati Forest as sentinels or biomonitors to determine the organic pollution in the atmosphere.

NewsPhytochromes: The ‘eyes’ that enable microalgae to find their way in the depths
By studying the light perception process of diatoms, a group of phytoplankton, scientists have discovered that these microalgae use light variation sensors which are codified in their genomes: phytochromes.

NewsGenome researchers unfurl protective mantle of influenza virus
The structure of the flu virus’s protective mantle and its interactions with its RNA have been described on an atomic scale by a research team for the first time.

NewsScientists discover new defense mechanism in bacteria
Researchers investigated a bacterial defence mechanism that uses cell-to-cell communication to ‘warn’ unaffected bacteria, which can then anticipate, shield themselves and spread the warning signal.

NewsRespiratory tract microbiome influences the severity of bacterial pneumonia
Pneumonia is an infection of the lung alveoli caused by bacteria, viruses or fungi. It is one of the leading causes of morbidity and mortality worldwide, representing a clinical and economic burden and a global public health problem.

NewsMolecule can block invasion of blood cells by malaria parasite
For the first time ever, a molecule able to prevent the invasion of blood cells by parasites of the genus Plasmodium, responsible for malaria, has been identified and described by scientists.

NewsPlankton trawl reveals new viruses related to both giant viruses and herpes viruses
Metagenomic data from Tara Oceans on marine plankton has enabled the discovery of a major group of DNA viruses found abundantly from the equator to the poles: mirusviruses.
