Study: Nanoparticle therapy restores tumor's suppressor in prostate cancer

Health
Sept. 17 (UPI) -- Using nanotechnology, researchers have developed a way to treat prostate cancer by restoring tumor suppressors, based on preclinical models in the lab. The loss of tumor suppressors, including genes such as PTEN and p53, helps cancer cells grow uninhibited. Researchers from the Harvard-affiliated Brigham and Women's Hospital and Children's Hospital in Boston, as well as the Memorial Sloan Kettering Cancer Center in New York, published their findings Monday in Nature Biomedical Engineering. While other researchers have focused on developing cancer therapies to target proteins and pathways highly active in cancer cells, the Boston-led team is studying ones that have been lost. "Our approach represents the convergence of nanotechnology and biology," co-corresponding author...

New nanoparticle could help solar panels convert unseen light into energy

Science
April 23 (UPI) -- Scientists have developed a new nanoparticle that can absorb near-infrared light and reemit it as visible light, which could allow solar panels to convert unseen light into usable energy.Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory coated tiny particles in organic dyes. The dyes work like antennae, which allowed scientists to fine-tune the nanoparticle's light-converting properties."These organic dyes capture broad swaths of near-infrared light," Bruce Cohen, a scientist at Berkeley Lab's Molecular Foundry, said in a news release.Most solar technologies that focus on visible light fail to absorb near-infrared light, allowing a solid chunk of the solar spectrum to go to waste. Roughly 44 percent of all light that hits Earth's surface...
