Seaweed, slime and socks: The science behind the suds

The novel phosphodiesterase enzyme, discovered by a team from Newcastle University, UK, is used by bacteria to unstick themselves from seaweed. The bacteria release an enzyme which breaks down the sticky molecules, naturally ...

Exploiting green tides thanks to a marine bacterium

Ulvan is the principal component of Ulva or "sea lettuce" which causes algal blooms (green tides). Scientists at the Station Biologique de Roscoff (CNRS/Sorbonne Université) and their German and Austrian colleagues have ...

Unexpected discovery about essential enzyme

The enzyme that produces DNA building blocks plays an important role when cells divide. In a new study, researchers have discovered for the first time that the so-called master switch of the enzyme can change locations—while ...

Researchers reveal how ocean bacteria use light to grow

Sunlight stimulates common ocean bacteria to use carbon dioxide for growth when high-quality organic carbon food sources are scarce, according to surprising research by an international team that includes a University of ...

It takes a(n academic) village to determine an enzyme's function

Scientists have sequenced the genomes of nearly 6,900 organisms, but they know the functions of only about half of the protein-coding genes thus far discovered. Now a multidisciplinary effort involving 15 scientists from ...

Brown algae reveal antioxidant production secrets

Brown algae contain phlorotannins, aromatic (phenolic) compounds that are unique in the plant kingdom. As natural antioxidants, phlorotannins are of great interest for the treament and prevention of cancer and inflammatory, ...

Boat owners can fight barnacles with new eco-friendly method

Barnacles can be found in all marine environments and are a major problem for both small boats and large ships. Barnacles accumulate on the hulls and can reduce the fuel economy of a vessel by up to 40 per cent, increasing ...
