Pigment explains why red heads are more at risk of skin cancer

A team of scientists have discovered that tiny chemical differences in how our skin reacts to ultraviolet light could explain why red heads are more likely to suffer skin cancer.

Carbohydrate-based vaccine against cancer?

Couldn't we be immunized against cancer? This sounds like a dream, but is in fact a thoroughly realistic research goal. American researchers have now taken an important step forward in the development of a cancer vaccine.

New method can detect 'mad cow' proteins in blood

Researchers at the University of Texas Medical Branch at Galveston (UTMB) have found a way to detect the malformed proteins in blood that cause "mad cow disease".

Malaria researchers find the parasite's housebreaking tool

Plasmodium falciparum, the most lethal malaria parasite, is a housebreaking villain of the red blood cell world. Like a burglar searching for a way in to his targeted premises, the parasite explores a variety of potential entry points to invade the red blood cells of its human victims. When a weak point is found, the intrusion proceeds.

New vaccine protects more effectively against tuberculosis

Max Planck researchers have uncovered the mechanism by which the new genetically engineered tuberculosis vaccine functions.

Both speaking and listening has detrimental effects on driving

New research shows that people have greater difficultly maintaining a fixed speed, or keeping their car safe in a single lane when performing tasks that simulated conversing on a mobile phone, than if they were driving without the distraction. Contrary to expectation, the speaking and listening were equally distracting.

Long-term hormone therapy used earlier in menopause is associated with fewer wrinkles

Long-term hormone therapy used earlier in menopause is associated with fewer wrinkles and less skin rigidity in postmenopausal women, Yale School of Medicine researchers report in the August issue of Fertility and Sterility.

Ataxin-1 affects the development of the nervous system

In some neurological diseases, too much of what is usually a good thing can be bad, said researchers at Baylor College of Medicine in a report in this week's issue of the journal Cell.

Immunity - another important function of the mitochondria

Researchers have discovered a surprise lurking inside mitochondria, the power plants that are present in every cell. It turns out that these powerhouses also contain a protein that triggers the immune system to attack viral invaders.

Neurotransmitter orexin influences reward processing - associated with pleasure and reward pathways in the brain

Researchers at the University of Pennsylvania School of Medicine have discovered that the recently identified neurotransmitter orexin (also known as hypocretin) influences reward processing by activating neurons in the lateral hypothalamus region of the brain.

Inflammation plays an important role in post-operative stroke

Duke University Medical Center researchers have discovered that patients who have two specific gene variants are more than three times as likely to suffer a stroke after heart surgery.

New strategy to turn off the function of a special group of T cells to suppress immune response to tumors

A special stretch of genetic material may turn off the immune suppression that stymies attempts to fight cancer with a vaccine, said researchers at Baylor College of Medicine (BCM) at Houston.

Stem cells with heart bypass surgery trial to begin

The University of Pittsburgh Medical Center (UPMC) has been granted approval by the U.S. Food and Drug Administration (FDA) to conduct a clinical trial to determine the safety and feasibility of injecting a patient's own bone marrow-derived stem cells directly into the heart during conventional heart bypass surgery.

Psychological distress of parents of children with spina bifida

Parents of children with spina bifida suffer from more psychological distress than parents of able-bodied children. Research published in the open access journal BMC Pediatrics reveals that having a child with spina bifida (SB) has a negative effect on parents' psychological well-being.

Protein snapin has potential as a drug target in therapies aimed at learning and memory disorders

Rutgers' Bonnie Firestein likens nerve cells to trees -- some are short and bushy with many branches while others are tall with a few branches coming out of one or two main trunks. Different branching patterns correlate with specific disorders and Firestein's quest is to discover how these dissimilar patterns come about and why.

The role of antigenic drive and tumor-infiltrating accessory cells in the pathogenesis of Helicobacter-induced MALT lymphoma

Research led by Dr. Anne Mueller at Stanford University School of Medicine demonstrates that successful eradication of Helicobacter may not prevent future aggressive gastric lymphoma since resting B cells are left behind.

Parts of the brain used in daydreaming are the same areas that fail in people who have Alzheimer's disease

Researchers who used five different medical imaging techniques to study the brain activity of 764 people, including those with Alzheimer's disease, those on the brink of dementia, and healthy individuals, have found that the areas of the brain that young, healthy people use when daydreaming are the same areas that fail in people who have Alzheimer's disease.

Coronary angioplasty increases risk of developing Alzheimer's disease

Boston University School of Medicine (BUSM) researchers have discovered that patients who have either coronary artery bypass graft surgery or coronary angioplasty are at an increased risk of developing Alzheimer's disease.

Stress does not appear to influence the outcome of IVF

New research from Sweden has shown that psychological stress does not appear to influence the outcome of IVF – good news for women who fear that the understandable anxiety that they suffer during fertility treatment might damage their chances of conceiving.

Brain plays an important role in the maintenance of proper bone density

The results of this research, involving a study of the activity of the protein interleukin 1 in the brain, comprise not only a breakthrough in understanding the regulation of bone density by the brain but also hold promise for the development of future treatment for osteoporosis, say the researchers.
