Fatty liver linked to survival in E. coli infection

Researchers found that male mice were three times more likely to survive E. coli infection due to sex-biased lipid metabolism, which may hold risks for males in today's high-calorie environment. The study identified a signaling pathway regulating lipids and growth hormone as potential therapeutic targets for fatty liver disease.

Virtual care associated with significant environmental and patient cost savings

A study by researchers at ICES, Lawson Health Research Institute, and Western University found that virtual care during the pandemic led to significant environmental and patient cost savings. Virtual visits represented approximately 0.2% of total annual carbon dioxide emissions in Ontario and estimated $63 million in patient cost savings.

How old is California’s Yosemite Valley?

Researchers from UC Berkeley used rock analysis to determine that the valley's impressive depth was formed since 10 million years ago, with most of it carved in the past 5 million years. The study employed a novel technique called helium-4/helium-3 thermochronometry to reconstruct the temperature history of the rocks.
