Why a hard day's work may be good for your health and a promising new treatment for HIV.

News on 6 anchor LeAnne Taylor has details in this Medical Update.

There may be real progress in the battle against HIV, doctors in France say a therapeutic vaccine may stop the spread of the disease. The team of scientists figured out how to combine a patient's own immune cells with inactive HIV to produce a vaccine.

If the vaccine proves successful after more testing, it will only be used for treating people already infected, not in preventing the disease.

This next story may sound obvious, but a new study shows diet and exercise are key to keeping the weight off. The research looked at 5,000 people who lost an average of 73 pounds and kept at least 30 pounds off for six years. While the subjects lost weight in different ways, they all kept the weight off by regularly exercising and eating a relatively low-calorie, low-fat diet.

If you find your job highly challenging, that may not only be good for the resume but good for your health. A new study find people who hold challenging jobs with opportunities for responsibility may be less likely to be diagnosed with Alzheimer's or other types of dementia.
