Shell game: How oysters enlist help from microbes

For an oyster, creating an internal environment for calcification that forms its distinctive hard shell is essential. But new Harvard research has found that these bivalves may outsource the work, coordinating with microbes ...

Turning penicillin into a lethal force against bacteria again

When many disease-causing bacteria encounter penicillin, they are not always destroyed right away, shifting into a temporary survival state called antibiotic tolerance. This state allows them to withstand drug levels that ...

Capsule technology opens new window into individual cells

Researchers have developed a capsule-based method that makes it possible to analyze the same cell through multiple experimental steps. The technology overcomes a long-standing limitation in cell research and could open new ...

Embryogenesis in 4D: A developmental atlas for genes and cells

How does a tiny cluster of cells become an embryo with a head, trunk, and tail? And how do thousands of genes coordinate this development? A new imaging method makes it possible to visualize the activity of thousands of genes ...

Wood surface treatment fights harmful bacteria

A University of Helsinki study has investigated bacterial adhesion, survival and transmission on untreated and treated wood surfaces under both laboratory and field conditions. The laboratory work focused on Staphylococcus ...

Tiny marine organism stressed by warmer Arctic waters

Some of the smallest marine species are actually the most important because all other life depends on them. Phytoplankton are probably the most important, but just above them in the food chain are zooplankton. In Norway's ...

Gut microbes: The secret to squirrel hibernation

When winter sets in and food becomes scarce, some mammals hibernate, entering a state of deep rest that slashes their energy needs and allows them to fast for months. However, fasting deprives them of essential nutrients, ...
