When scientists talk about demonstrating, we’re usually referring to pedagogical lab sessions. Yesterday, scientists traded lab coats for loudspeakers during a political demonstration outside the UK Houses of Parliament.

The rally saw ‘several dozen’ researchers, politicians and patient group reps supporting the Human Fertilisation and Embryology Bill, which would modernise UK embryology laws (Nature News has the full details).

Protests over biological research are normally associated with restricting or barring new technologies, so its refreshing to hear the researchers and patients speaking up. Member of Parliament Evan Harris explained why the bill is important:

“The rights of patients to access the potential therapies coming from this research should not be denied because of the dogmatic religious views, however sincerely held, of individuals or religious leaders.”

The House of Commons later endorsed the new legislation, which would, among other things, allow the creation of animal–human embryos. MPs later supported the new laws by 340 votes to 78. After closer scrutiny of the bill, its individual components will be voted on next week.
