A new technology based on the interpretation of light reflected off cells will make it faster and more efficient for researchers to document how the nucleus, which contains a cell's DNA and controls its actions, changes shape in response to its environment. The technique will enable researchers for the first time to watch some changes in the living cell as they happen.
The Duke University bioengineers who developed the new method and demonstrated its effectiveness believe ...
Bioptigen, a spinoff company co-founded by Duke biomedical engineer Joseph Izatt, has won the Frost & Sullivan 2007 North American Optical Coherence Tomography Excellence in Research Award.

High quality night vision and infrared cameras are critical for a variety of tasks ranging from security in banks and museums to observing nocturnal animals to military troop safety. In the past, improving the quality of photographs meant using ever larger camera lenses. However, in these and other applications it is important for cameras to be as small as possible.

The World Health Organization estimates that each year 300 million to 500 million cases of malaria occur and more than one million people die of malaria. A mosquito-borne disease caused by a parasite, malaria causes fever, chills, and flu-like illness. While there is currently no malaria vaccine approved for human use, the disease can be successfully treated if caught early. But some strains, such as the falciparum malaria strain, are particularly deadly.

The concept of invisibility has long been relegated to the realm of science fiction, from H.G. Wells' Invisible Man to Harry Potter, but those days are gone. Last year, David R. Smith, Augustine Scholar and professor of electrical and computer engineering, and his colleagues reported a blueprint for a device that would make invisibility possible, at least at microwave frequencies. Months later, the first such invisibility cloak, built from artificial composite materials called metamaterials, was ...
