The era is long gone when a romantic breakup meant ripped-up photos and burned love letters. Today, digital photos and emails can be quickly deleted but the proliferation of social media has made forgetting a bigger chore. What about the ubiquitous digital records of a once beloved that lurk on Facebook, Tumblr, and Flickr?...

During the late Pleistocene, a diverse assemblage of large-bodied mammals inhabited the "mammoth steppe" of northern Eurasia and Beringia. Of the large predators -- wolves, bears, and big cats -- only the wolves and bears were able to maintain their ranges well after the end of the last ice age. A...

In many neurodegenerative diseases the neurons of the brain are over-stimulated and this leads to their destruction. After many failed attempts and much scepticism this process was finally shown last year to be a possible basis for treatment in some patients with stroke. But very few targets for...

Studies of human mobility usually focus on either the small scale -- determining the origins, destinations and travel modes of individuals' daily commutes -- or the very large scale, such as using air-travel patterns to track the spread of epidemics over time. The large-scale studies, most of which...
