NewsScientists solve mystery of bacterial scavenging machinery
Scientists investigated how the oleate shuttle from FakB2 to FakA kinase works in the Fak system, which is exploited by the zoonotic pathogen Streptococcus suis (S. suis) pathogen to scavenge exogenous fatty acid (eFA).

NewsClimate anomalies may play a major role in driving cholera pandemics
New research suggests that an El Niño event may have aided the establishment of a novel cholera strain during an early 20th-century pandemic, suggesting climate anomalies could create opportunities for the emergence of new cholera strains.

NewsWarming stops tiny organisms working together
The single-celled organism Paramecium bursaria can absorb and host algae (Chlorella spp), providing benefits for both, but when scientists made the water 5°C warmer, the partnership stopped working – and the algae may even become parasitic.

NewsCopper oxide nanoparticles to counter pathogens are synthesized from mango
Researchers have synthesized green copper oxide nanoparticles from Mangifera indica leaf extract. They showed potent activity against gram-positive and negative bacteria, as well as fungicidal effects on persimmon fruit pathogens.

NewsWhat shapes a virus’s pandemic potential? SARS-CoV-2 relatives yield clues
Two of the closest known relatives to SARS-CoV-2 — a pair of bat coronaviruses discovered by researchers in Laos — may transmit poorly in people despite being genetically similar to the COVID-19-causing virus, a new study reveals.
