Having a healthy gut may well depend on maintaining a complex signaling dance between immune cells and the stem cells that line the intestine. Scientists report significant new insight into how these interactions control intestinal regeneration after an infection. It's a dance that ensures repair after a challenge, but that also goes awry in aging fruit flies. The work offers important new clues into possible causes of age-related human maladies, including IBS and colorectal cancer.
Frailer older patients are at higher risk of readmission to hospital or death within 30 days after discharge from a general internal medicine ward, but health care professionals can assess who is at risk using the Clinical Frailty Scale, according to a study in CMAJ.
In an African study supported by the Canadian government, a new tool -- the 'flocked swab' -- helped reveal that one-third of babies hospitalized with severe diarrhea were discharged with an undiagnosed, treatable infection. The results could prompt global rethink of how to manage diarrhea diseases, the world's 2nd leading cause of death of children under 5.
Certain blind individuals have the ability to use echoes from tongue or finger clicks to recognize objects in the distance, and use echolocation as a replacement for vision. Research done by Dr. Mel Goodale, from the University of Western Ontario, in Canada, shows echolocation in blind individuals is a full form of sensory substitution, and that blind echolocation experts recruit regions of the brain normally associated with visual perception when making echo-based assessments of objects.
New research has led the FDA to approve use of a drug to treat the effects of radiation exposure following a nuclear incident. The drug, Neupogen, is the first ever approved for the treatment of acute radiation injury.
In a new study led from Sweden's Karolinska Institutet, researchers report that people can be conditioned to associate images with particular pain responses - such as improved tolerance to pain -- even when they are not consciously aware of the images.
A new article publishing online today in the Quarterly Journal of Medicine has reported the first case showing an association between exposure to head injuries in rugby union players and an increased risk in neurodegenerative disease.
School disciplinary actions handed down to students at Utah public schools disproportionately impact American Indian children over all other ethnicities enrolled in the state's public education system, new research from the University of Utah S.J.

Ethical dilemmas can present a self-control conflict between pursuing immediate benefits through behaving dishonestly and pursuing long-term benefits through honesty. New research has found that factors that facilitate self-control for other goals can also promote self-behavior. The researchers conclude that identifying a self-control conflict and anticipating a temptation are two necessary preconditions for ethical decision making.
Psychoacoustics identifies five basic types of emotional speech: angry, fearful, happy, sad and neutral. In order to fully understand what's happening with speech perception, a research team at the University of Texas at Austin studied how depressed individuals perceive these different kinds of emotional speech in multi-tonal environments. They will present their findings at the 169th ASA meeting, held this week in Pittsburgh.
