Science Highlights • January 28, 2005
A bioengineered material now plays a crucial role in treating conditions ranging from incontinence to burns.
Science Highlights • December 15, 2004
Robotic technology may accelerate the rehabilitation process and reduce the costs of physical therapy for individuals whose arms are paralyzed as a result of stroke.
Science Highlights • November 8, 2004
A new fiber optic probe plugs into a biopsy needle and takes advantage of the important differences between how malignant and benign tissue respond to light. The device may improve the accuracy of conventional needle biopsies.

Hard wiring the brain? Almost. Brain computer interface technologies that capture electrical brain waves as individuals imagine performing certain activities and translate the waves into computer commands will soon allow patients to operate word-processing programs, and perhaps even electric wheelchairs or robotic arms.
Science Highlights • September 21, 2004
A biodegradable polymer may reduce the extent of arterial injuries and repeat blockage seen with rigid metal stents used to treat coronary artery disease.
Science Highlights • August 2, 2004
A liquid polymer gel that can be poured into torn cartilage tissue may offer a new approach to healing worn out joints. Tested on rabbits, the gel adapts to the shape of the tear and becomes the scaffolding for the body’s own cartilage cells to make new tissue.

DNA sequencing promises to improve the way in which diseases such as cancer are diagnosed, monitored, and treated. The technology relies on detecting fluorescent signals created when pieces of DNA bind together on a microchip. An emerging technology—electrophoresis on microchips—has aided DNA sequencing by miniaturizing processing technologies. Miniaturization has reduced the time needed to analyze samples and decreased the sample size required for testing.

In the future, a patient in need of a new bone or bone section may be able to have one made using a mold, a gel solution, and a few drops of mesenchymal stem cells (MSCs). These versatile precursor cells, found in bone marrow and fat tissue, can transform into different cell types, including bone, cartilage, and skeletal muscle.

Molecular probes offer researchers a new tool to gather information about the fundamental actions and reactions that occur in cells and molecules. By using fluorescent probes that are compatible with biological material, researchers can obtain color images of cellular and molecular activity. One form of molecular probe that has generated recent interest is semiconductor nanocrystals. These microscopic particles exhibit unique optical properties that offer major advantages over conventional fluorescent dyes for imaging biological samples.

Shorter epilepsy surgery times may result from a new imaging system that integrates information about brain anatomy, biochemistry, electrical activity, and blood flow and may allow surgeons to more precisely pinpoint, and then remove, damaged brain tissue that causes seizures.
