The marketing, prescribing and selling of testosterone and growth hormone as panaceas for age-related problems is disease mongering, write the authors of a paper in Journal of the American Geriatrics Society .

Disease mongering is inventing new broader definitions of disease in conjunction with widespread marketing to increase sales of specific drugs and therapies.

When we look at a known word, our brain sees it more like a picture than a series of letters needing to be processed, according to a new paper in the Journal of Neuroscience.

Neurons respond differently to real words, such as turf, than to nonsense words, such as turt, showing that a small area of the brain is "holistically tuned" to recognize complete words, says the study's senior author, Maximilian Riesenhuber, PhD, who leads the Georgetown University Medical Center Laboratory for Computational Cognitive Neuroscience. 

The brain learns words quickly by tuning neurons to respond to a complete word, not parts of it.  

Young children who received the 4CMenB vaccine as infants to protect against serogroup B meningococcal disease had waning immunity by age 5, even after receiving a booster at age 3 ½, according to new research in CMAJ (Canadian Medical Association Journal)

Serogroup B meningococcal disease is the leading cause of meningitis and blood infections in developed countries. Infants and young children under the age of 5 years are especially at risk, and there is a second peak of cases in the late teenage years.

Is Myopia the new Rickets? A new study compares the history of school myopia with the bone disease rickets. During the 17th century, rickets was common among children in England and then reached epidemic levels through northern Europe and North America. In some cities, 80 percent of children were affected.

The remedy proved elusive until the 1920s, when scientists discovered that a lack of sunlight, resulting in vitamin D deficiency, was the cause of rickets. 

Ulnar collateral ligament (UCLR) reconstruction surgery, called "Tommy John Surgery" after the New York Yankees pitcher who made it famous in 1974, is now a common procedure for Major League Baseball pitchers after they get a damaged or torn ulnar collateral ligament.

It has been a boon for athletes. It had once been a career-ending injury but John pitched for 14 more years and racked up 164 more victories. But it has limits, according to a new study, namely in athletes who have it twice.

When most people think of quantum mechanics they think of Schroedinger's cat, a thought experiment describing a cat inside a closed box, that may be either dead or alive. Only when the classical physics world enters the box do we know. But what is the tipping-point between that cat's life and death, when does quantum behavior give way to classical physics?

Where, on the small scale, is Schroedinger's cat small enough size to be perceived as being both alive and dead at the same time?

A new study in Physical Review Letters has an answer, thanks to a fiber-based nonlinear process that allowed physicists to observe how, and under what conditions, classical physical behavior emerges from the quantum world.
