Microbes that live in the gut don’t just digest food. They also have far-reaching effects on the immune system. Now, a new study shows that a particular gut microbe can prevent severe flu infections in mice, likely by breaking down naturally occurring compounds — called flavonoids — commonly found in foods such as black tea, red wine and blueberries.
In order to reduce the cost of next-generation polymer electrolyte fuel cells for vehicles, researchers have been developing alternatives to the prohibitively expensive platinum and platinum-group metal (PGM) catalysts currently used in fuel cell electrodes. New work at Los Alamos and Oak Ridge national laboratories is resolving difficult fuel-cell performance questions, both in determining efficient new materials and understanding how they work at an atomic level. The research is described this week in the journal Science.
The cold-loving fungus (Pseudogymnoascus destructans, or Pd) that causes white-nose syndrome, a disease that has killed millions of North American bats during hibernation, could also spread in summer months. Bats and humans visiting contaminated caves and mines can inadvertently contribute to the spread of the fungus, according to a recently published study by the U.S. Geological Survey.
USGS scientists tested samples collected from bats, the environment and equipment at eight bat hibernation sites in Kentucky, Indiana, Ohio, Tennessee and Virginia. They found that bats occupying such sites in summer can harbor the Pd fungus on their skin, and that Pd is more readily detectable in their guano, or feces.
Known as a nodosaur, this 110 million-year-old, armored plant-eater is the best preserved fossil of its kind ever found.
A Métis student in the University of Saskatchewan School of Public Health, Adams is one of 16 young leaders from across Canada appointed to the Your Energy Future program.
Participants in the year-long program, delivered in partnership by the Public Policy Forum and leadership development fellowship Action Canada, will become change-makers in Canada’s energy agenda. They develop strategies to prepare Canadian people, communities and governments to successfully transition to a low-carbon, clean energy future.
Artificial light disrupts nocturnal pollination and leads to a reduced number of fruits produced by the plant.
