Friday links: Female Mathematicians, Robots and Comets

Okay, time for interesting stories from all over.


This one's my favorite. A recent study has shown that girls are just as good at maths as boys. Finally, vindication!

Another hot topic. There just might be concrete evidence that the Tungunska explosion of 1908 might have been caused by a comet. Evidence? Acid rain and iridium!

Alright, this one's a bit warped. And sick. And so wrong. A robot named Hero is going to scan under vehicles in case terrorists, along with the tired, the hungry and the poor try to get into the UK.
