Like Sleeping Beauty, some research lies dormant for decades, IU study finds

Oldest old less likely to be investigated or aggressively treated after surgery

Road traffic noise linked to heightened risk of mid-riff bulge

Complex signaling between blood and stem cells controls regeneration in fly gut
(Buck Institute for Age Research) 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.

Motherhood permanently alters the brain and its response to hormone therapy later in life
(Canadian Association for Neuroscience) Research by Liisa Galea, University of British Columbia, suggests the form of estrogens used in Hormone Therapy (HT) and previous motherhood are critical to explain why HT has variable effects on cognitive functions. Estradiol had beneficial effects while estrone did not. Furthermore, the effects of estrone also depended on the experience of motherhood: estrone-based HT impaired learning in middle-aged rats that were mothers, while it improved learning in rats that were not.

Can you see what I hear? Blind human echolocators use visual areas of the brain
(Canadian Association for Neuroscience) 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.
