Humans tend to move faster when they think they're going to get a reward. A new experiment explores the pathways in the brain that may be behind these patterns.

A new targeted PET/CT tracer can detect treatment response in rheumatoid arthritis patients in as little as four weeks, and potentially even at the start of treatment, according to new research published in The Journal of Nuclear Medicine. Compared to the three to six months currently required to establish treatment efficacy, this new imaging technique could help determine the patients who are most likely to respond sooner, allowing non-responders to pursue more effective therapies.

Circulating tumor DNA, or ctDNA, can predict metastatic risk in patients who receive bladder-sparing treatment for muscle-invasive bladder cancer, but it is not a good predictor of local recurrence within the bladder, according to new data presented today by Fox Chase Cancer Center researchers.

A team from the Monash University Biomedicine Discovery Institute in Australia has identified a tick-derived evasin that can bind to two major classes of chemokines, a discovery that is important for the development of therapeutics targeting inflammatory and autoimmune diseases. Until now, scientists had identified only evasins that selectively block chemokines within a single class.
