New Technology – No Cancer Left Behind

A team of scientists at Washington University School of Medicine in St. Louis and the University of Arizona in Tucson led by Samuel Achilefu have created a pair of high-tech glasses that help surgeons visualize cancer cells during surgeries, which glow when viewed through the eyewear. The technology, reported in the SPIE Journal of Biomedical Optics, incorporates custom video and a head-mounted display that is capable of capturing signal from any fluorescent molecular agent injected into a patient that attaches to cancer cells, making them glow. Achilefu, a professor of radiology and of biomedical engineering at WUSTL and co-leader of the Oncologic Imaging Program at Siteman Cancer Center, and his team developed the technology that incorporates custom video, a head-mounted display, and a targeted molecular agent injected into a patient that attaches to cancer cells, making them glow.

Caffeine & Dementia

More Coffee or Tea? Caffeine May Protect Your Brain from Dementia

What: A recent review article in the Journal of Nutrition, Health and Aging showed the potential long-term benefit of caffeine use in lowering dementia risk. Researchers reviewed the existing data to consider the possible benefits of caffeine for reducing dementia risk, as well as the potential mechanisms by which caffeine may work to lower that risk. They found a strong association between regular use of coffee, tea, or other caffeine-containing foods and reduced dementia risk.

Why This Matters: Caffeine has been associated with improved everyday cognitive performance. However, its effect on long-term dementia risk remains unclear, as does the means by which it might reduce that risk.
