Molecular imaging enables earlier, individualized treatment of thyroid cancer

In a study to determine the diagnostic value of molecular imaging in nodal staging of patients with thyroid cancer, researchers were able for the first time to accurately distinguish between cancerous cells in regional lymph nodes and normal residual thyroid tissue directly after surgery.

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.

Alcohol consumption during pregnancy damages offspring's white matter - brain's connective network

One part of the prenatal brain that may be particularly sensitive to alcohol's effects is white matter, nerve fibers through which information is exchanged between different areas of the central nervous system.

How mirror neurons allow us to learn and socialize by going through the motions in the head

The old adage that we can only learn how to do something by trying it ourselves may have to be revised in the light of recent discoveries in neuroscience.

Miniature therapeutic ultrasound device

A prototype of a therapeutic ultrasound device, developed by a Cornell graduate student, fits in the palm of a hand, is battery-powered and packs enough punch to stabilize a gunshot wound or deliver drugs to brain cancer patients.

SRS microscopy helps track molecules and drugs in live cells

A new type of highly sensitive microscopy developed by researchers at Harvard University could greatly expand the limits of modern biomedical imaging, allowing scientists to track the location of minuscule metabolites and drugs in living cells and tissues without the use of any kind of fluorescent labeling.
