Bird genes are multitaskers, say scientists

Scientists from the University of Sheffield have found that although male and female birds have an almost identical set of genes, they function differently in each sex through a mechanism called alternative splicing.

New method allows precise gene control by light

A novel optical switch makes it possible to precisely control the lifespan of genetic copies. These are used by the cell as building instructions for the production of proteins. The method was developed by researchers from ...

Primate brain size does not predict their intelligence

Chimpanzees, gorillas and orangutans are our closest relatives, and like us they have relatively large brains and they are very intelligent. But do animals with larger brains really perform better in cognitive tests? A research ...

The surprising organisation of avian brains

Birds and mammals have the largest brains in relation to their body. Apart from that, however, they have little in common, according to scientific opinion since the 19th century: mammalian brains have a neocortex, i.e. a ...

RAP tag: A new protein purification approach

Whether it's our diets, building strength, or as part of medical advancements, it is no secret that proteins form an important part of our lives. Tracking how proteins work and move in cells, and purifying engineered proteins, ...

The molecules responsible for transcriptional bursting

New insights into what causes neighboring, genetically identical stem cells in mouse embryos to behave differently in terms of the proteins they produce could have implications for regenerative medicine and the early detection ...

A worm's view on immunity

All higher organisms have an immune system that constitutes a biological defense mechanism to protect the body from pathogens and foreign substances. It consists of a complex network of different organs, cell types and molecules ...

The male Y chromosome does more than we thought

New light is being shed on a little-known role of Y chromosome genes, specific to males, that could explain why men suffer differently than women from various diseases, including COVID-19.
