Social animals often develop relationships with other group members to reduce aggression and gain access to scarce resources. In wild chacma baboons the strategy for grooming activities shows a certain pattern across the ...

Enzyme controls transport of genomic building blocks

Our DNA and its architecture are duplicated every time our cells divide. Histone proteins are key building blocks of this architecture and contain crucial information that regulates our genes. Danish researchers show how ...

Ultra sensitive detection of radio waves with lasers

Radio waves are used for many measurements and applications, for example, in communication with mobile phones, MRI scans, scientific experiments and cosmic observations. But 'noise' in the detector of the measuring instrument ...

New technology detect cellular memory

Cells in our body are constantly dividing to maintain our body functions. At each division, our DNA code and a whole machinery of supporting components has to be faithfully duplicated to maintain the cell's memory of its ...

A 'smoking gun' on the Ice Age megafauna extinctions

It was climate that killed many of the large mammals after the latest Ice Age. But what more specifically was it with the climate that led to this mass extinction? The answer to this is hidden in a large number of sediment ...

Bacteria recycle broken DNA

Bacteria recycle broken DNA that bacteria can take up small as well as large pieces of old DNA from this scrapheap and include it in their own genome. This discovery may have major consequences – both in connection with ...
