Direct detection of circulating tumor cells in blood samples

Enhanced Glow

09-Aug-2019

Tumor cells circulating in blood are markers for the early detection and prognosis of cancer. However, detection of these cells is challenging because of their scarcity. In the journal Angewandte Chemie, scientists have now introduced an ultrasensitive method for the direct detection of ...

The scientific benefits of Rudolph's red nose

23-Dec-2015

We're all familiar with the story of Rudolph the Red-Nosed Reindeer by Robert L. May (a class of 1926 Dartmouth alumnus) but scientifically speaking, what are the optical benefits of a shiny red nose on a foggy Christmas Eve? Nathaniel J. Dominy , Professor of Anthropology at Dartmouth, explores ...

Fruit flies have latent bioluminescence

New findings hold promise for expanded use of bioluminescence imaging tools

14-Apr-2014

New research from scientists at the University of Massachusetts Medical School shows that fruit flies are secretly harboring the biochemistry needed to glow in the dark —otherwise known as bioluminescence. The key to activating this latent ability is a novel synthetic analog of D-luciferin ...

Symbiotic bacteria program daily rhythms in squid using light and chemicals

03-Apr-2013

Glowing bacteria inside squids use light and chemical signals to control circadian-like rhythms in the animals, according to a study to be published in mBio®. The Hawaiian bobtail squid, Euprymna scolopes, houses a colony of Vibrio fischeri bacteria in its light organ, using the bacteria at night ...

Ultrasensitive imaging method uses gold-silver 'nanocages'

14-Apr-2010

New research findings suggest that an experimental ultrasensitive medical imaging technique that uses a pulsed laser and tiny metallic "nanocages" might enable both the early detection and treatment of disease. The system works by shining near-infrared laser pulses through the skin to detect ...
