Studies and Analyses

Researchers Jonathan Flombaum and Dr. Laurie Santos, both from Yale University, have found that rhesus monkeys consider whether a competitor can or cannot see them when trying to steal food.

Working with semi-free-ranging rhesus monkeys on the island of Cayo Santiago in Puerto Rico, Flombaum and Santos set up a food competition game: Lone monkeys were approached by two human “competitors.” Each competitor had a grape affixed to a platform by his feet. In each experiment, one of

The willingness to call out in distress to get help from others appears to be regulated by two brain systems with very different responsibilities, according to a study by researchers at the University of Wisconsin-Madison.

“These findings have far-reaching implications because they help clarify how a balance of two important brain systems can influence an individual’s behavior and emotional expression in times of need,” says Ned Kalin, senior author on the study and chair

After angioplasty is performed to widen clogged arteries, surgeons frequently use tiny wire-mesh tubes called stents to keep blood vessels open. But despite stenting, scar tissue can form to create new blockages — a process called in-stent restenosis (ISR). At present, vascular brachytherapy (catheter-based delivery of intracoronary radiation) is the only therapeutic modality proven to effectively reduce in-stent restenosis. But a team of Emory cardiology researchers presented a study at the

If a mammogram or sonogram suggests that a woman has breast cancer, an MRI should be done to help determine whether there actually is a cancer and if so, what are the woman’s best treatment options, a new study shows. The study, done in a large community hospital, found that MR images, which were acquired and analyzed in a specific way, can help identify if a lesion is benign or malignant and can show cancers that would otherwise be missed.

“This is the first time a prospective st

Researchers at the University of York are investigating a new method of organising care for some of the three million adults in the UK who suffer from clinical depression.

The innovative regime known as ’collaborative care’ has been developed over the last decade, principally in the USA, but it has never been used in the UK. It involves a case manager, supervised by experts in mental health, working alongside the general practitioner, to improve the management of patien

Three studies are underway at the NYU School of Medicine to find out whether short-term counseling can ease the psychological stress and depression of people with Alzheimer’s disease and their family members. These studies were inspired by the success of a previous trial at the NYU School of Medicine that showed that even a short period of counseling can have a long-term beneficial impact on the emotional well-being of people taking care of spouses with Alzheimer’s disease.
