A recent critical assessment of software tools represents a key step toward taming the 'Wild West' nature of the burgeoning field of metagenomics.
At first glance, the yeast Candida krusei seems as innocuous as microbes come: it’s used for fermenting cocoa beans and gives chocolate its pleasant aroma. But it’s increasingly being found as a pathogen in immunocompromised patients — and C. krusei infections aren’t always easy to cure.
An investigation of the different economic values of giant sea bass finds they are worth more alive as undersea wonders than as commercial catch.
Scientists have shown that Parisian street gutters are oases of microscopic life, home to microalgae, fungi, sponges, and mollusks. Grouped into communities, these microorganisms may help clean rainwater and urban waste by decomposing solid debris and pollutants. A deeper understanding of the role and composition of these communities could help elucidate the services rendered by gutter ecosystems. The researchers' findings are the first to reveal the unsuspected biodiversity of microscopic life in Paris city streets.
Investigators have identified a new molecular pathway that controls lifespan and healthspan in worms and mammals. Researchers have shown that worms with excess levels of certain proteins lived longer and healthier than normal worms. In addition, mice with excess levels of these proteins demonstrated a delay in blood vessel dysfunction associated with aging. The study has major implications for our understanding of aging and age-associated disorders.
