2012 CODiE Award for Best Online Science or Technology Service, Bibliogo is unlike any other literature acquisition and management tool for Life Science and Engineering professionals and the companies they work for.

"Basically, any computing device (or switch, or router) that is based on light requires a nonlinear interaction between different light beams, but light doesn't like to do nonlinear stuff. With current technology, you can get efficient nonlinear optical interactions, but the hardware is kind of bulky or very delicate. Not the sort of thing you want to put in a billion devices. What my friends in Barcelona have demonstrated is that it's possible to create a relatively efficient optical nonlinear interaction in a nano-structured metallic surface. "

"For 20 years, researchers have reported a potential link between gum disease and atherosclerotic heart disease from hardening of the arteries or stroke. "The message sent out by some in health-care professions, that heart attack and stroke are directly linked to gum disease, can distort the facts, alarm patients and perhaps shift the focus on prevention away from well-known risk factors for these diseases," said Dr. Peter Lockhart, a professor and chair of oral medicine at the Carolinas Medical Center in Charlotte, N.C. Lockhart wrote the heart group's new position statement in the journal Circulation. The statement was prepared after a three-year analysis of about 600 studies by an expert panel led by a dentist and a cardiologist."

"We provide novel evidence for the effects of metabolic dysfunctions on brain function using the rat model of metabolic syndrome induced by high fructose intake. * We describe that the deleterious consequences of unhealthy dietary habits can be partially counteracted by dietary supplementation of n-3 fatty acid. * High sugar consumption impaired cognitive abilities and disrupted insulin signalling by engaging molecules associated with energy metabolism and synaptic plasticity; in turn, the presence of docosahexaenoic acid, an n-3 fatty acid, restored metabolic homeostasis. * These findings expand the concept of metabolic syndrome affecting the brain and provide the mechanistic evidence of how dietary habits can interact to regulate brain functions, which can further alter lifelong susceptibility to the metabolic disorders.

"The project was kick-started by a huge public response to the team's research into the genetics of gut bacteria. In a previous study the researchers found that certain gut-specific genetic markers were related to obesity and other diseases. "I got between 50 and 100 e-mails from regular people having problems with the stomach or diarrhoea and wondering if we can help them," Peer Bork, a biochemist and co-creator of MyMicrobes, told Nature. This new website will build on that work, whilst also providing support for concerned members of the public."

Bacteria are often social creatures. Suspended in colonies of varying shapes and sizes, these microbes communicate with their brethren and even other bacterial species - interactions that can sometimes make them more deadly or more resistant to antibiotics. Now, bacterial colonies sculpted into custom shapes by a 3-D printer could be a key to understanding how some antibiotic-resistant infections develop. The new technique uses methods similar to those employed by commercial 3-D printers, which extrude plastic, to create gelatin-based bacterial breeding grounds. These microbial condos can be carved into almost any three-dimensional shape, including pyramids and nested spheres.

A small change to the theory of gravity implies that our universe inherited its arrow of time from the black hole in which it was born.
