Dye-doped DNA nanofibers emit white light

A team of researchers at the University of Connecticut and the US Air Force Research Laboratory has now successfully used the electrospinning of DNA complexes to produce nanofibers that incorporate two different fluorescing dyes in such a way that energy can efficiently be transferred from one dye to the other. The color of the resulting fluorescence can be controlled by means of the ratio of the two dyes.

Filling fullerenes with radio-active material for radiation therapy

Virginia Tech chemistry Professor Harry C. Dorn, Emory and Henry College chemistry Professor James Duchamp, and Panos Fatouros, professor and chair of the Division of Radiation Physics and Biology at the Virginia Commonwealth University School of Medicine have co-invented a hands-off process for filling fullerenes with radio-active material.

Normal cells far from cancer give nanosignals of trouble

A new Northwestern University-led study of human colon, pancreatic and lung cells is the first to report that cancer cells and their non-cancerous cell neighbors, although quite different under the microscope, share very similar structural abnormalities on the nanoscale level.

Scientists track chemical changes in cells as they endure extreme conditions

One of nature's most gripping feats of survival is now better understood. For the first time, scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory observed the chemical changes in individual cells that enable them to survive conditions that should kill them.

New metamaterial brings us nearer to the dream of invisibility

A group of researchers from the Department of Physics at UAB have designed a device, called a dc metamaterial, which makes objects invisible under certain light by making the inside of the magnetic field zero but not altering the exterior field. The device, which up to date has only been studied in theoretical works, thus acts as an invisibility cloak, making the object completely undetectable to these waves.

Q is for quantum and "Q-life"

Features in the July issue of Physics World include a close look at how physics is informing our understanding of cells and of the brain, while Paul Davies, a physicist, astrobiologist and director of BEYOND: Center for Fundamental Concepts in Science at Arizona State University, suggests there are tentative signs that life itself may have arisen as a result of physicists' long-cherished theory of quantum mechanics.

Environmental Working Group releases their 2009 Sunscreen Report

The Environmental Working Group (EWG), a United States-based non-governmental organization that works to expose threats to health and the environment, has released their 2009 Sunscreen Report. The investigators expected to recommend against the use of micronized and nano-sized zinc oxide and titanium dioxide sunscreen, but after months of research and analysis of nearly 400 peer-reviewed studies, they found themselves recommending some sunscreens that may contain nanoparticles.

Tiny sensor measures real-time water stress in living plants

The device is an embedded microsensor capable of measuring real-time water stress in living plants. In theory, the sensor will help vintners strike the precise balance between drought and overwatering - both of which diminish the quality of wine grapes.
