 Specialized cellular structures may hold clues to health effects of psychological stressSpecialized cellular structures may hold clues to health effects of psychological stress
 
How does psychological stress translate into physical health effects? A key piece of the puzzle may be found in specialized cellular structures known as mitochondria, according to a pair of articles in the January issue of Psychosomatic Medicine: Journal of Biobehavioral Medicine, the official journal of the American Psychosomatic Society.

Study uncovers potential targets for treatment of aggressive triple-negative breast cancersAs part of a breast-cancer diagnosis, doctors analyze the tumor to determine which therapies might best attack the malignancy.
 
 
 Salk scientists identify molecular target of experimental Alzheimer’s drug
 
Salk scientists identify molecular target of experimental Alzheimer’s drugThe experimental drug J147 is something of a modern elixir of life; it's been shown to treat Alzheimer's disease and reverse aging in mice and is almost ready for clinical trials in humans.
 
 
 Viral replication process weak spot may help develop cure for infections
 
Viral replication process weak spot may help develop cure for infectionsResearchers at the Morgridge Institute for Research believe they have identified a weak spot in the replication process of positive-strand RNA viruses, which could yield treatment for viral infections such as Zika, Polio, Chikungunya, Hepatitis C and even common cold viruses.
