Higher antibiotic doses may make bacteria 'fitter': study

Using higher doses of antibiotics in a bid to tackle the growing problem of drug resistance may end up strengthening certain bacteria, according to research released on Wednesday that highlights a previously unthought-of ...

New, active viruses found at depths of over 400 meters

Researchers who investigated water-filled cracks in the bedrock at a depth of 448 meters outside Oskarshamn in Sweden have found completely new viruses and vibrant bacterial and viral communities. The findings show that viruses ...

Climate impacts drive east-west divide in forest seed production

Younger, smaller trees that comprise much of North America's eastern forests have increased their seed production under climate change, but older, larger trees that dominate forests in much of the West have been less responsive, ...

New theory for how snowflakes grow

Scientists have discovered what drives the delicate and complex microcosm of tiny terraces, pyramids and craters found on the surface of ice. These miniature structures, hidden beneath a thin premelting layer of water, develop ...

How bacteria adapt their machinery for optimum growth

The most important components for the functioning of a biological cell are its proteins. As a result, protein production is arguably the most important process for cell growth. The faster the bacterial growth rate, the faster ...
