I tend to take alarmist claims about the demise of species with a large grain of salt. As supported by this story about a species of North American bumblebee which virtually disappeared and which has now reappeared.

I don’t believe the scientists who say they know the secret of Usain Bolt and his speed.

Matt Ridley compares HS2 to Hadrian’s Wall.

John Hawks considers the Denisovans and the pre-Toba, post-Toba question.

Joschka Fischer who was German Foreign Minister and Vice Chancellor from 1998-2005 considers Egypt after Morsi.
