The scientists have discovered that the nanoparticles are extremely effective at killing certain blood vessel cells that tumors need in order to spread to other parts of the body.

Although the environmental benefit of using CFLs is clear, they contain mercury and thus require careful cleanup if broken (see guidelines below for details). Researchers and students at Brown University have discovered a new material that readily absorbs mercury. They hope this material can be included in each bulb's packaging to make cleanup and recycling easier and safer.
