Brain imaging (MRI/PET) bring us closer to earlier detection of Alzheimer's

Changes in the brain measured with MRI and PET scans, combined with memory tests and detection of risk proteins in body fluids, may lead to earlier and more accurate diagnosis of Alzheimer's, according to new research reported today at the Alzheimer's Association 2009 International Conference on Alzheimer's Disease (ICAD 2009) in Vienna.

Computer-guided nanoparticle therapy destroys tumors

Gold nanoshells are among the most promising new nanoscale therapeutics being developed to kill tumors, acting as antennas that turn light energy into heat that cooks cancer to death. Now, a multi-institutional research team has shown that polymer-coated gold nanorods one-up their spherical counterparts, with a single dose completely destroying all tumors in a nonhuman animal model of human cancer.

Cryo-electron tomography shows immature HIV in 3D

Scientists at the European Molecular Biology Laboratory (EMBL) and the University Clinic Heidelberg, Germany, have produced a three-dimensional reconstruction of HIV (Human Immunodeficiency Virus), which shows the structure of the immature form of the virus at unprecedented detail. Immature HIV is a precursor of the infectious virus, which can cause AIDS.
