Engineers in Florida have ignited certain small particles with low-power lasers, a finding that could have ramifications in medicine. With as little as 500 mW, researchers were able to release the energy stored in functionalized fullerenes, which are biologically safe molecules that can be directed to cancerous tumors.

Magic bullets, also called silver bullets, because of the folkloric belief that only silver bullets can kill supernatural creatures, remain the goal of drug development efforts today. A team of scientists at Washington Univ. in St. Louis is currently working on a magic bullet for cancer. But their bullets are gold rather than silver.

The film "Avatar" isn't the only 3-D blockbuster making a splash this winter. A team of scientists from Houston's Texas Medical Center this week unveiled a new technique for growing 3-D cell cultures, a technological leap from the flat petri dish that could save millions of dollars in drug-testing costs.

Conventional biological wisdom holds that living cells interact with their environment through an elaborate network of chemical signals, which is most therapies rely on drugs that block chemical signals. Scientists can now show, however, for the first time, that direct physical force can also change the way cellular proteins conduct chemical activity.

Scientists from Sydney's Garvan Institute of Medical Research have published recent research describing gene expression in a prostate cancer cell: it’s more sweeping, more targeted and more complex than previously thought. The study shows that changes within the cell’s epigenome can silence nearly 3% of the cell's genome.

A Univ. of Missouri researcher is developing a tiny sensor, known as an acoustic resonant sensor, that is smaller than a human hair and could test bodily fluids for a variety of diseases, including breast and prostate cancers.

Taking gold nanoparticles to the cancer cell and hitting them with a laser has been shown to be a promising tool in fighting cancer, but what about cancers that occur in places where a laser light can’t reach? Scientists at the Georgia Institute of Technology have shown that by directing gold nanoparticles into the nuclei of cancer cells, they can not only prevent them from multiplying, but can kill them where they lurk.

Using lasers and nanoparticles, scientists at Rice Univ. have discovered a new technique for singling out individual diseased cells and destroying them with tiny explosions. The scientists used lasers to make "nanobubbles" by zapping gold nanoparticles inside cells.

Scientists at Georgia Tech and the Ovarian Cancer Institute have further developed a potential new treatment against cancer that uses magnetic nanoparticles to attach to cancer cells, removing them from the body. The treatment, tested in mice in 2008, has now been tested using samples from human cancer patients.

Scientists at the Univ. of California, Berkeley, have created smart nanoprobes that may one day be used in the battle against cancer to selectively seek out and destroy tumor cells, as well as report back on the mission's status.
