One-Size-Fits-All Approach Can Lead to Diabetes Over-Treatment

January 13, 2015 10:30 am | by Yale | News | Comments

Diabetes treatments have saved many lives, but in older patients with multiple medical conditions, aggressively controlling blood sugar with insulin and sulfonylurea drugs, could lead to over-treatment and hypoglycemia (low blood sugar), according to new research by Yale School of Medicine researchers.                          

What the Nose Knows

January 13, 2015 10:23 am | by CSHL | News | Comments

The nose, of course, knows nothing. The information we gather from the basic odor-detection task performed by molecular receptors in the nose needs to be processed in the brain’s olfactory bulb and olfactory cortex in order for us to make sense of an odor and glean what we need to know to take action. 

Mechanism Insights Into SMA Suggest New Treatment Paths
