Crabs' memory of pain confirmed by Queen's academic

New research published by a Queen's University Belfast academic has shown that crabs not only suffer pain but that they retain a memory of it. The study, which looked at the reactions of hermit crabs to small electric shocks, was carried out by Professor Bob Elwood and Mirjam Appel from the Sch...

X-effect: female chromosome confirmed a prime driver of speciation

Researchers at the University of Rochester believe they have just confirmed a controversial theory of evolution. The X chromosome is a strikingly powerful force in the origin of new species. Biologists have argued for years whether the X chromosomethe female chromosome in most animalsplays a spec...
