Electronic nose developed to sniff out colon diseases

In much the same way as dogs can be trained to detect some diseases through their keen sense of smell, technology can help create electronic devices capable of performing this same task. This is precisely what a team of researchers from the Gandia campus of Valencia’s Polytechnic University and the La Fe Health Investigation Institute have achieved, developing a prototype of an electronic nose that can distinguish between patients with Crohn’s disease and ulcerative colitis.

Rousing Masses to Fight Cancer with Open Source Machine Learning

Here’s an open invitation to steal. It goes out to cancer fighters and tempts them with a new program that predicts cancer drug effectiveness via machine learning and raw genetic data. The researchers who built the program at the Georgia Institute of Technology would like cancer fighters to take it for free, or even just swipe parts of their programming code, so they’ve made it open source.

Researchers watch in real time as fat-encased drug nanoparticles invade skin cells

Some anti-cancer drugs are encapsulated to allow gradual release, spreading their effect over a longer time. For example, one formulation of the chemotherapy doxorubicin ( the FDA-approved drug Doxil®) encloses molecules of the drug in fatty nano-spheres called liposomes, which allows the drug to circulate longer in the blood. However, the use of liposome “capsules” often comes with side-effects.
