Heritability explains fast-learning chicks

Both genetic and environmental factors explain cognitive traits, shows a new study carried out on red junglefowl. Researchers at Linköping University in Sweden have shown that the ability of fowl to cope with difficult learning ...

DNA structure influences the function of transcription factors

Substances known as transcription factors often determine how a cell develops as well as which proteins it produces and in what quantities. Transcription factors bind to a section of DNA and control how strongly a gene in ...

When beneficial bacteria knock but no one is home

The community of beneficial bacteria that live in our intestines, known as the gut microbiome, are important for the development and function of the immune system. There has been growing evidence that certain probiotics—therapies ...

Beta cells from love handles

Researchers at ETH Zurich have managed to use a synthetic genetic program to instruct stem cells taken from fatty tissue to become cells that are almost identical to natural beta cells. This brings them a major step closer ...

Far-reaching benefits from canine cancer research

A study mapping genes associated with two cancers common in golden retrievers could lead to better prevention and treatment of the disease in dogs as well as similar cancers in people.

Complex grammar of the genomic language

A new study from Sweden's Karolinska Institutet shows that the 'grammar' of the human genetic code is more complex than that of even the most intricately constructed spoken languages in the world. The findings, published ...
