This week, the Science Weekly team discuss dark energy and the even darker matter of the gender gap with astrophysicist Sarah Bridle - recipient of a Women in Science fellowship. It's sponsored by a well-known cosmetics company - is it worth it? Do awards like this actually help to de-beard science? And isn't this a wider societal problem anyway?
Also in the show, we hear from comedian Bill Bailey about his admiration for the anthropologist Alfred Russel Wallace - the forgotten hero of evolution.
In our news roundup, Ian Sample tells us about a British team's plans to create the world's first human stem cells from hybrid embryos, and why flat-screen televisions are the latest environmental hazard. Meanwhile, Nell Boase bemoans the shrinking of the solar system.
Finally, Alok Jha investigates the science of jelly by taking a trip to University College London, and speaking to a jellymonger and uber-chef, Heston Blumenthal.
