A single genetic change in gut bacteria alters host metabolism

A study published in eLife found that deleting a single gene from a particular strain of gut bacteria causes changes in metabolism and reduced weight gain in mice. The researchers discovered that this genetic change altered the levels of certain bile acids, leading to a preference for metabolizing fats rather than carbohydrates.

Nitric oxide tells roundworms to avoid bad bacteria

A new study published in eLife reveals that roundworms, specifically Caenorhabditis elegans, use nitric oxide gas as a sensory cue to avoid the pathogenic bacteria Pseudomonas aeruginosa. The protein thioredoxin plays a crucial role in regulating the temporal dynamics of the worm's response to the gas.

Behavior-influencing policies are critical for mass market success of low carbon vehicles

A new study emphasizes the importance of behavioral policies in encouraging the adoption of alternative-fuel vehicles, citing consumer preferences and climate policies as key factors. The research suggests that a combination of policies can increase the market share of low-carbon vehicles to over 25% by 2050.

How many people die from tuberculosis every year?

A study by ISGlobal reveals significant discrepancies in global tuberculosis death estimates between the World Health Organisation (WHO) and the Institute for Health Metrics and Evaluation (IHME), primarily due to differences in methodology and data sources. The researchers identify a dozen countries with notable variations, emphasizin...
