Antibiotic-resistant bacteria is a serious public health threat. Understanding the biology of these bacteria—such as how they synthesise their protective capsules—is essential for developing new strategies to counter antibiotic resistance. 

Chronic jet lag causes drastically different effects on male and female metabolism in mice, say researchers from Kyushu University. The study, published in the journal, Biology of Sex Differences, found that the body clocks of female mice are more easily disrupted than the clocks of male mice, and revealed opposing metabolic effects; jet-lagged male mice gained weight and developed glucose intolerance, while jet-lagged females lost weight compared to female mice without jet lag.
