Sleep is regulated by two processes: circadian and homeostatic. Circadian regulation affects the timing of sleep, and the homeostatic mechanism affects the need for sleep.

While scientists and physicians know what happens if you don't get six to eight hours of sleep per night, investigators have long been puzzled about what controls the actual need for sleep. Researchers at the University of Pennsylvania School of Medicine might have an answer, at least in fruit flies. In a recent study of fruit flies, they identified a gene that controls sleep.

Researchers have created a 3D image of a material referred to as "liquid smoke." Aerogel, also known as liquid smoke or "San Francisco fog," is an open-cell polymer with pores smaller than 50 nanometers in diameter.

Aerogel is a form of nanofoam, an engineered material designed for high strengh-to-weight ratio. Such nanofoam structires are also present in the fields of geology, phospholipids, cells, bone structure, polymers and structural materials, wherever lightness and strength are needed.

For the first time, Lawrence Livermore and Lawrence Berkeley scientists have peered into this material and created three-dimensional images to determine its strength and potential new applications.

An enriched extract of Boswellia serrata (the 'Indian Frankincense' herb) has been proven to reduce the symptoms of osteoarthritis. Research published today in Arthritis Research & Therapy has shown that patients taking the herbal remedy showed significant improvement in as little as seven days.

Osteoarthritis is the most common form of arthritis; it commonly affects weight-bearing joints such as the knees and hips, along with the hands, wrists, feet and spine. The symptoms include pain, stiffness and limited movement. This randomised, double-blinded, placebo-controlled trial of 70 patients will be of great interest to sufferers, especially those who don't get adequate relief from existing treatments.

LONDON, July 29 /PRNewswire/ -- A recent AHPMA survey among continence care professionals has painted a bleak picture on the current state of many continence services in the UK, largely due to lack of Government funding. The survey finds that continence care staff are striving for quality care within extremely limited resources.

The survey received 148 responses, which show an unacceptably low level of funding in many Primary Care Trusts; morale being lower than five years ago in over half of Trusts; increased workloads and vacancies not being filled. It demonstrates a wide variance in Continence Services and shows little evidence that the 'Good practice in continence services' document published by the Department of Health in 2000 has been considered by Trusts.

Less able to achieve their life goals, women end up unhappier than men later in life – even though they start out happier, reveals new research by Anke Plagnol of the University of Cambridge, and University of Southern California economist Richard Easterlin.

Plagnol and Easterlin's study, forthcoming in the Journal of Happiness Studies, is the first to use nationally representative data spanning several decades to examine the role of unfulfilled desires in a person's sense of well-being.

As the researchers explain, expectations of success may vary among those raised in different generations (i.e., an economic depression). Data sets from a range of time periods may also have different demographic compositions.
