For years, researchers have worked to develop novel molecules for therapeutic or research purposes, and have relied on directed evolution as a powerful technique for generating molecules that exhibit the properties they want.

Richard Wagner examines a classic experiment in evolutionary biology and points out pitfalls in the experimental design.

New WiFi virus that can spread through densly populated areas as effectively as the common cold identified.

Top quarks are the heaviest and among the most puzzling elementary particles.

Clemson University researchers have developed nanoparticles that can deliver drugs targeting damaged arteries, a non-invasive method to fight heart disease.

With more than 1,600 products using nanotechnology on the market, a team of undergraduate researchers at North Dakota State University (NDSU) is examining how people perceive such products and how these products might ultimately affect the environment.

An innovative vaccine technology makes use of reengineered salmonella to deliver protective immunity. If such recombinant attenuated salmonella vaccines, or RASVs, can be perfected, they hold the promise of safe, low-cost, orally-administered defenses against viral, bacterial, fungal and parasitic infections.

University of Idaho professor’s project turns cow manure into biodegradable plastic.

A recent study suggests that self-reported memory complaints might predict clinical memory impairment later in life.

“With new insights into both the pathogen and its potato host, we can use GM technology to tip the evolutionary balance in favour of potatoes and against late blight.”
