How monkeys decide to explore new options
Washington, Sep 5 (ANI): Researchers at Duke University Medical Center have used brain scans in monkeys to predict when monkeys decide if they want to switch from exploiting a known resource to exploring newer options.
Such a trade-off is easy for many, but not for those with conditions such as Alzheimer’s disease or obsessive-compulsive disorder who [...]

Findings on how bladder cells detect bacteria may help prevent urinary tract infections
Washington, August 21 (ANI): Researchers at Duke University Medical Center may be close to devising a new way to stop or prevent the urinary tract infections (UTIs), for they have discovered how cells within the bladder [...]
Darwin wrongly called the appendix a biological ‘remnant’, say researchers
Washington, August 21 (ANI): Charles Darwin was wrong when he theorized that the appendix in humans and other primates was the evolutionary remains of a larger structure, called a cecum, which was used by now-extinct ancestors for digesting food, according to research collaborators from three U.S. institutions.

Biomarker that predicts response to hepatitis C treatment identified
London, Aug 17 (ANI): Duke University Medical Center scientists have discovered the first genetic marker that predicts response to hepatitis C treatments.
The researchers say the biomarker predicts who is most likely to respond to treatment and who isn’t.
“For geneticists, understanding response to treatment for hepatitis C infection has been almost like a Holy Grail,” says [...]

New light-emitting biomaterial may revolutionise tumour imaging
London, Aug 11 (ANI): Scientists from University of Virginia have developed new light-emitting biomaterial that could improve tumour imaging.
The new material is an oxygen nanosensor that couples a light-emitting dye with a biopolymer and simplifies the imaging of oxygen-deficient regions of tumours. [...]
