This image of a woven biomaterial "scaffold" for growing replacement cartilage won first place in the Federation of American Societies for Experimental Biology (FASEB) first-ever "Bio-Art" imaging competition in May, 2012. Professor Farshid Guilak and post-doctoral researcher Frank Moutos of Duke's Orthopaedic Research Laboratory "seed" these scaffolds with living cells that grow to become new tissue while the woven biomaterial slowly dissolves away.
Dressed in a navy blue t-shirt and jeans with a brownish-blonde crew cut, Joshua Loyal appears to be a typical college junior. Yet as he chats about his freshman summer searching for elusive and undiscovered sub-atomic particles, it's clear that, at twenty-one, Loyal has moved beyond average.

Almost every day since July 1960 someone has been watching the chimpanzees in what is now Gombe National Park in Tanzania, making careful notes of their every action from dawn to dusk.

Nico Katsanis, PhD, says the new model of doing science should be to abandon the model.
“A lot of the problems we are now facing are experimentally intractable through a single approach,” he says. At the same time, research is becoming so specialized that the journals of one researcher’s discipline read almost like gibberish to a researcher in another field.

Like most people, Landon Cox uses online social networking sites such as Facebook, MySpace, and Flickr. He has a Facebook account and he regularly posts pictures of his two young daughters on Flickr. In fact, he said, sites like these are central to his life: “It’s the main way I communicate with other people.”
Post-doctoral fellow Anna Loksztejn of the Center for Biologically Inspired Materials created this image of aggregated insulin proteins using atomic force microscopy. Colors are used to show details of structure, giving crucial information on how misfolded proteins can be stacked into fiber-like structures called amyloids.
Human memory – taking in information, storing it and retrieving it accurately – is key to a variety of crucial decisions made in medicine or law and physical movements like dance.
Cognitive scientist Ruth Day wants to understand it better.
"I see people who are doing well but not well enough," she says. "Maybe they prescribe or dispense the wrong drug. Maybe they can't remember what they've just seen."
Or maybe a dancer twirls to the left when all the other dancers are going right.
