Scientists have found that autophagy can have a down side, destroying the pancreas by prematurely activating a digestive enzyme.

Heavy babies arthritis risk

People who have a birth-weight over 10 pounds are twice as likely to develop rheumatoid arthritis when they are adults compared to individuals born with an average birth-weight.

Personalised HIV therapy

Researchers are using minute, naturally occurring proteins called zinc fingers to engineer T cells to one day treat AIDS in humans.

Unhealthy meals harms memory

Treating symptomatic myocardial bridging

Researchers have developed a new classification system that may help guide doctors' decision-making regarding patients who have a heart abnormality.

Smart neural implants

Researchers have taken the concept of brain-machine interfaces a step further, devising a way for computerised devices not only to translate brain signals into movement but also to evolve with the brain as it learns.

Protein loss and dementia

Researchers have discovered that a protein that suppresses cell division in brain cells effectively "puts the brakes" on the dementia that comes with Alzheimer's disease.

Nature's West Nile check

Helping the elderly sleep

Electrical discharge in the brain

After a stroke, even unaffected areas of the brain are at risk – depolarization waves arise at the edges of the dead tissue and spread through the adjacent areas of the brain. If these waves are repeated, more cells die.

Stress early, allergies later

Stress events during childhood are increasingly suspected of playing a role in the later development of asthma, allergic skin disorders, or allergic sensitisations.

Walking for health

A new study shows that a variety of interventions designed to promote walking can effectively motivate individuals to initiate walking behaviours.

Psychosocial issues and AIDS

Psychosocial influences such as stress have been neglected in biomedical and treatment studies involving people infected with HIV, yet they are now known to have significant health impacts.

Inherited melanoma risk

When people know the results of genetic tests confirming they have inherited an increased risk of developing melanoma, they follow skin cancer screening recommendations more proactively.

Menopausal brain change

Many women experience menopausal changes in their body including hot flashes, moodiness and fatigue, but the changes they don't notice can be more dangerous.
