Diet has rapid effects on sperm quality

Sperm are influenced by diet, and the effects arise rapidly. This is the conclusion of a study by researchers at Linköping University, in which healthy young men were fed a diet rich in sugar. The study, which has been published ...

Finally, machine learning interprets gene regulation clearly

In this age of "big data," artificial intelligence (AI) has become a valuable ally for scientists. Machine learning algorithms, for instance, are helping biologists make sense of the dizzying number of molecular signals that ...

Chimpanzees spontaneously dance to music

A pair of researchers at Kyoto University has found that chimpanzees will spontaneously dance to music. In their paper published in Proceedings of the National Academy of Sciences, Yuko Hattori and Masaki Tomonaga describe ...

'Living fossil' may upend basic tenet of evolutionary theory

The field of evolutionary biology has seen its share of spirited debates. But if there's one principle that virtually every expert in the field agrees on, it's that natural selection occurs at the level of the genome.

First evidence found of tool use by seabirds

Three researchers from the University of Oxford and the South Iceland Nature Research Centre have found evidence of tool use by puffins—the first evidence of tool use by any seabird. In their paper published in Proceedings ...
