Study shows hairy skin does not become less sensitive with age

Our sense of touch is generally thought to decline with age, just like the other senses. However, a study has now shown for the first time that age-related decline in sensitivity only happens in hairless skin like the tip of the index finger, but not in the hairy cheeks and forearms. The authors speculate that the exceptional sensitivity of the cheeks throughout life is due to our evolutionary history as social primates, for whom touch is an important method of communication.

Ultrasound beam triggers ‘nanodroplets' to deliver drugs at exactly the right spot

Conventional drug delivery is inefficient and imprecise. Through a series of preclinical experiments, researchers from the University of Utah have optimized a novel, targeted method of delivery through nanodroplet carriers, which are triggered to release their drug at exactly the desired spot by a focused beam of ultrasound. Their results showed that nanodroplets with a core of perfluorooctylbromide are stable, efficient in delivery, and well tolerated. Clinical experiments are likely to follow.
