Nanoparticles may provide safe pain control on the battlefield

University of Michigan scientists have received a pilot grant of nearly $1.3 million from the Defense Advanced Research Projects Agency to test whether nanoparticles can solve a pressing problem in battle zones like Iraq: how to administer sustained, safe doses of the most effective painkillers to injured soldiers, long before they can reach expert medical help.

Baby boomers are starting to feel the aches, pains and weight gain of aging

Because they, like others, want to feel younger for longer, food companies and food researchers are striving to meet their needs. Increased amounts of nutritional supplements and antioxidants, including calcium, vitamin D and zinc, can slow the rate of age-related disease and increase the number of healthy years, according Jeffrey Blumberg, a nutrition scientist at Tufts University and speaker here at the Institute of Food Technologists Annual Meeting & Food Expo.

How immune cells catch pathogens

To protect us from disease our immune system employs macrophages, cells that roam our body in search of disease-causing bacteria. With the help of long tentacle-like protrusions, macrophages can catch suspicious particles, pull them towards their cell bodies, internalise and destroy them.

Magnetic nano tweezers show how cancer drug works

The annoying bulges of an over-wound telephone cord that shorten its reach and limit a caller's motion help to explain why drugs called camptothecins are so effective in killing cancer cells, according to investigators at St. Jude Children's Research Hospital and Delft University of Technology.

Multifunctional nanoparticle platforms for targeting and imaging cancer cells

There has been much recent interest in how nanotechnology will impact the field of medicine. Unfortunately, a number of promising nanostructured systems have turned out to be extremely toxic to humans, thus precluding their use in clinical applications and dashing hopes of an early success for the interdisciplinary field of nanobiotechnology.
