NewsStudy reveals the gut microbiome’s role in controlling the body’s thermostat
The average basal temperature of the human body has decreased since the 1860s for unknown reasons, but a new study points to the gut microbiome as a potential regulator of body temperature, both in health and during life-threatening infections.

NewsShort-lived volcanic island harboured sulphur-metabolizing microbes
Researchers discovered a unique microbial community that metabolizes sulphur and atmospheric gases, similar to organisms found in deep sea vents or hot springs, on a volcanic island that only lasted for seven years.

NewsLong-term projects reveal how warming planet will impact microbe carbon cycling
A team of researchers led by the University of Massachusetts Amherst has helped to untangle one of the knottiest questions involving soil microbes and climate change: what effect does a warming planet have on the microbes’ carbon cycling?

NewsResearchers pinpoint enzyme that limits electrosynthesis by Shewanella
Researchers at Michigan State University have identified an enzyme that is a limiting factor to microbial electrosynthesis by Shewanella oneidensis, a bacterium that could potentially capture carbon dioxide emissions to produce useful materials.
-
NewsSemi-living cyborg cells could be tools for health and environment
Biomedical engineers at the University of California have created semi-living ’cyborg cells’ retaining the capabilities of living cells, but unable to replicate.
-
NewsSalmonella exposure poses a risk for colon cancer
Researchers who studied human colon cancer tissue samples and animal models have found that exposure to salmonella was linked with colon cancers that developed earlier and grew larger.
-
NewsProbiotic markedly reduces staph colonisation in phase 2 trial
A approach to control Staphylococcus aureus bacterial colonization in people—using a probiotic instead of antibiotics—was found to be safe and highly effective in a Phase 2 clinical trial.

NewsChange in genetics of SARS-CoV-2 evolved to counter weakness caused by the virus’s initial mutation
Researchers at Johns Hopkins Medicine say their new studies suggest that the first pandemic-accelerating mutation in the SARS-CoV-2 virus, which causes COVID-19, evolved as a way to correct vulnerabilities caused by the mutation that started the SARS-CoV-2 pandemic.
