The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Smokers with stroke in the family six times more likely to have stroke too

A new study shows that people who are smokers and have a family history of brain aneurysm appear to be significantly more likely to suffer a stroke from a brain aneurysm themselves.

Matrix fragments trigger fatal excitement

Shredded extracellular matrix (ECM) is toxic to neurons. Chen et al. reveal a new mechanism for how ECM demolition causes brain damage. The study will appear in the December 29, 2008 issue of The Journal of Cell Biology (www.jcb.org).

Barcode chip enables cheaper, faster blood testing

A new barcode chip developed by a multi-institutional team of investigators promises to revolutionize diagnostic medical testing. In less than 10 minutes and using just a pinprick's worth of blood, the chip can measure the concentrations of dozens of proteins, including those that herald the presence of diseases such as cancer and heart disease.

Targeted nanoparticles deliver therapeutic DNA to cancer cells

Given that cancer is a disease caused by gene mutations, cancer researchers have been striving to develop gene therapies aimed at correcting these mutations. However, these efforts have been hobbled by the difficulty in safely and efficiently delivering anticancer genes to tumors. Nanoparticles, however, may solve these delivery issues, and two recently published studies, using two different types of nanoparticles, lend credence to that hypothesis.

Physicians perform rare surgery to restore hearing to a deaf patient

Marisela Leon, 44, has neurofibromatosis type 2 -- a rare genetic condition that causes tumors to grow on nerves in the brain or spinal cord, but most commonly on the auditory nerve. Leon lost her hearing more than four years ago when surgery to remove a tumor damaged her auditory nerve.
