When tsetse flies fall for a host, they keep coming back for more

If you like a restaurant first time around, you're likely to go back, aren't you? Well the same goes, more or less, for tsetse flies, as researchers from CIRAD, CIRDES and the University of Neuchâtel have recently demonstrated.

Two proteins called BERT and ERNI interact in embryos to control brain development

Scientists at University College London have discovered how two proteins called BERT and ERNI interact in embryos to control when different organ systems in the body start to form, deepening our understanding of the development of the brain and nervous system and expanding our knowledge of stem cell behavior.

Discovery of 480 genes that control human cell division

A team of U.S., Israeli and German scientists used computational biology techniques to discover 480 genes that play a role in human cell division and to identify more than 100 of those genes that have an abnormal pattern of activation in cancer cells.

Gene therapy can reduce long-term drinking among rodents

Just as the risk of developing alcoholism is strongly influenced by genetic factors, mutations in gene coding - such as the aldehyde dehydrogenase (ALDH2*2) allele - also appear to protect against the risk.

Avalon Explosion shaped early history of multicellular life

Scientists have known for some time that most major groups of complex animals appeared in the fossils record during the Cambrian Explosion, a seemingly rapid evolutionary event that occurred 542 million years ago.

Scientists find missing evolutionary link using tiny fungus crystal

The crystal structure of a molecule from a primitive fungus has served as a time machine to show researchers more about the evolution of life from the simple to the complex.

Sea-cucumber protein may provide methods of preventing the transmission of malaria

Scientists have genetically engineered a mosquito to release a sea-cucumber protein into its gut which impairs the development of malaria parasites, according to research out today (21 December) in PLoS Pathogens.
