Listening to jazz can make your food taste better. The genre of background music can affect how satisfying something tastes and so may impact on how much is eaten, research reveals.
Researchers from the University of Arkansas played four types of music - classical, jazz, hip hop and rock - while people ate.
Participants found the food more satisfying when jazz was played and less so when hip hop was in the background. There was no effect for rock or classical music.
'People often consume food and beverages in the presence of background music. Nevertheless, little attention has been paid to the influence of sound on sensory perception and acceptance of foods,' researchers said.
The reasons why jazz and hip hop had such an effect were unclear.

Alcohol jab soothes chronic back pain

Doctors are using a drop of alcohol to  help back pain. Chronic lower back pain  is often the result of a bulging disc pressing  on nerves.
Now an alcohol-based gel is being used to treat patients with lumbar (or lower back) disc problems as part of a trial at University Hospital, Limoges, France.

 

The gel is injected into the problem disc and the alcohol reacts with the tissue in the soft core, making it shrink. This reduces pressure on the nerves and eases pain.
The treatment is being compared with other standard treatments including painkillers, muscle relaxants, physiotherapy and transcutaneous electrical nerve stimulation, where electrical impulses block pain signals.

How a brain zapper may help anorexia

Stimulating the brain with electrodes is being tested as a treatment for anorexia.
Around half of patients - mainly young women - do not respond to other medical treatment such as family therapy, behavioural therapy and psychotherapy.
Research suggests that the nucleus accumbens, part of the brain involved in registering reward, does not work properly in anorexia patients - the reward system drives the motivation to eat.
The new technique, known as deep brain stimulation, involves stimulating this area with electrodes placed inside the brain to make it more active.
It is already used to treat several conditions, including Parkinson's disease.
The technology is undergoing clinical trials at Oxford University and Shanghai.
