Mind-controlled prosthetic arms that work in daily life are now a reality

For the first time, robotic prostheses controlled via implanted neuromuscular interfaces have become a clinical reality. A novel osseointegrated (bone-anchored) implant system gives patients new opportunities in their daily life and professional activities.

In January 2013 a Swedish arm amputee was the first person in the world to receive a prosthesis with a direct connection to bone, nerves and muscles. An article about this achievement and its long-term stability will now be published in the Science Translational Medicine journal.

Price gap between more and less healthy foods grows

A new study, published today in the journal PLOS One, tracked the price of 94 key food and beverage items from 2002 to 2012. Its findings show that more healthy foods were consistently more expensive than less healthy foods, and have risen more sharply in price over time.

Food prices in the UK have risen faster than the price of other goods in recent years, and this new research shows that the increase has been greater for more healthy foods, making them progressively more expensive over time.

While less healthy foods had a slightly greater price rise relative to 2002, the absolute increase was significantly more for more healthy foods – a total average increase of £1.84 per 1000kcal for more healthy food across the decade, compared to £0.73 for less healthy food.

Why do women struggling with low sexual desire not seek treatment?

Low sexual desire is common among both pre- and post-menopausal women. It can cause personal distress, harm relationships, and have a negative impact on body image and self confidence. Yet few women seek medical care for this condition, and the reasons are explored in a timely article in Journal of Women’s Health, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers.

In the article “Attitudinal Survey of Women Living with Low Sexual Desire,” Sheryl A. Kingsberg, PhD, Case Western Reserve University School of Medicine (Cleveland, OH), presents the results of a survey of women’s attitudes toward low sexual desire and their awareness of its treatability as a medical condition. Dr. Kingsberg found that more than one-quarter of premenopausal and one-third of post-menopausal women were very dissatisfied with their current level of sexual desire. Most had not discussed their low sexual desire with their health care providers because they felt uncomfortable or embarrassed or were not aware that it is a treatable condition.

Near death experiences – major new study

Recollections in relation to death, so-called out-of-body experiences (OBEs) or near-death experiences (NDEs), are an often spoken about phenomenon which have frequently been considered hallucinatory or illusory in nature; however, objective studies on these experiences are limited.
