New polymer nanoparticles can generate heat and kill colorectal cancer cells

Researchers at Wake Forest Baptist Medical Center have modified electrically-conductive polymers, commonly used in solar energy applications, to develop revolutionary polymer nanoparticles (PNs) for a medical application. When the nanoparticles are exposed to infrared light, they generate heat that can be used to kill colorectal cancer cells.

BRIGHTs bind to biomarkers of disease and light up to reveal their location

Called BRIGHTs, the tiny probes described in the online issue of Advanced Materials on Nov. 15, bind to biomarkers of disease and, when swept by an infrared laser, light up to reveal their location.

Textile pressure ulcer prevention

The skin is the most versatile of our organs: It protects the body from environmental effects, contributes to the body's immune system and supports metabolic functions such as breathing.

Nanofiber technique to build new nerves from stem cells

Every week in his clinic at the University of Michigan, neurologist Joseph Corey, M.D., Ph.D., treats patients whose nerves are dying or shrinking due to disease or injury.

Alternate method to precisely tag breast cancer tumors

When surgeons operate to remove a tumor, determining exactly where to cut can be tricky. Ideally, the entire tumor should be removed while leaving a continuous layer of healthy tissue, but current techniques for locating the tumors during surgery are imprecise. Now a multidisciplinary team from the University of California, San Diego, is developing an alternate means of precisely tagging breast cancer tumors for removal or targeted destruction.

Research team finds elusive self-healing formulation for defense, aerospace

A research team at the University of Nevada, Reno has developed a new environmentally-friendly coating for aluminum to replace the carcinogenic chromate coatings used in aerospace applications. The chromate conversion coatings have been used for more than 50 years to protect aluminum from corrosion.

Skin's outmost layer is the first line of defense against UV radiation

Reinhold Dauskardt, PhD, of Stanford's Department of Materials Science and Engineering has been studying skin for years. But when he sent his students to look for data on the mechanical properties of skin, they came back empty-handed. A lot was known about skin structure and disease, but few papers actually talked about its mechanical function - its ability to stretch and resist tension without tearing.

Modulating immune response to injury could accelerate regeneration of peripheral nerves

Modulating immune response to injury could accelerate the regeneration of severed peripheral nerves, a new study in an animal model has found. By altering activity of the macrophage cells that respond to injuries, researchers dramatically increased the rate at which nerve processes regrew.

New technique can manipulate and measure magnetic particles without contact

If you throw a ball underwater, you'll find that the smaller it is, the faster it moves: A larger cross-section greatly increases the water's resistance. Now, a team of MIT researchers has figured out a way to use this basic principle, on a microscopic scale, to carry out biomedical tests that could eventually lead to fast, compact and versatile medical-testing devices.

Legs of grasshoppers and crabs have ideal shape to resist bending and compression

Researchers from Trinity College Dublin have recently shown that the legs of grasshoppers and crabs have the ideal shape to resist bending and compression. If human leg bones were built the same way, they could be twice as strong.

Harvard experts create biocompatible hydrogel

A team of experts in mechanics, materials science, and tissue engineering at Harvard have created an extremely stretchy and tough gel that may pave the way to replacing damaged cartilage in human joints.

Scientists identify specific role of RESA protein in modulating blood circulation

When the parasite responsible for malaria infects human red blood cells, it launches a 48-hour remodeling of the host cells. During the first 24 hours of this cycle, a protein called RESA undertakes the first step of renovation: enhancing the stiffness of the cell membranes.

Johns Hopkins team creates synthetic protein that can help locate tumors

Johns Hopkins researchers have created a synthetic protein that, when activated by ultraviolet light, can guide doctors to places within the body where cancer, arthritis and other serious medical disorders can be detected.

Nanoparticle may bring great benefits to emergency treatment of brain-injury victims

A nanoparticle developed at Rice University and tested in collaboration with Baylor College of Medicine (BCM) may bring great benefits to the emergency treatment of brain-injury victims, even those with mild injuries.

New neurotechnology aims to help rehabilitate stroke survivors

What comes naturally to most people - to think and then do - is difficult for stroke patients who have lost the full use of their limbs. New research by Rice University, the University of Houston (UH) and TIRR Memorial Hermann aims to help victims recover that ability to the fullest extent possible with a $1.17 million grant from the National Institutes of Health (NIH) and the President's National Robotics Initiative (NRI).

Two Johns Hopkins scientists receive NCI grant for Provocative Questions project

Two Johns Hopkins scientists are among the first recipients of grants geared to answer "Provocative Questions" in cancer research, a new project funded by the National Cancer Institute (NCI), part of the National Institutes of Health (NIH). Cynthia Sears, M.D., and Peter Searson, Ph.D., will receive more than $500,000 combined in the first of five years of funding.
