Conquering metal fatigue

Novel laminated nanostructure gives steel bone-like resistance to fracturing under repeated stress CAMBRIDGE, Mass. — Metal fatigue can lead to abrupt and sometimes catastrophic failures in parts that undergo repeated loading, or stress. It’s a major cause of failure in structural components of everything from

A light rain can spread soil bacteria far and wide, study finds

Global precipitation may account for 1 to 25 percent of bacteria emitted from land by Jennifer Chu, MIT News Office CAMBRIDGE, Mass. — A good rain can have a cleansing effect on the land. But an MIT study published today in Nature Communications reports that, under

Microbiome diversity is influenced by chance encounters

Study finds a role for randomness in the composition of the gut’s microbe populations by Anne Trafton, MIT News Office CAMBRIDGE, MA: Within the human digestive tract, there are trillions of bacteria, and these communities contain hundreds or even thousands of species. The makeup of
