Spectroscopy is the study of the interaction between radiation (electromagnetic radiation, or light, as well as particle radiation) and matter.

Snoring and sleep apnoea damage the brain

Australian researchers have found that the effects of sleep apnoea on the brain of a sleeping patient are far worse than previously thought.

New tag could enable more detailed structural studies of mammalian proteins

To say our genes are resourceful is a gross understatement. Through ingenious combinations of a paltry 20 amino acids, the basic building blocks of life, genes engineer all of the tissues and organs that are the marvel of our working bodies.

Calorie restriction causes temporal changes in the liver and skeletal muscle metabolism

Moderate calorie restriction causes temporal changes in the liver and skeletal muscle metabolism, whereas moderate weight loss affects muscle, according to a new study in Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute.

Glutamate identified as predictor of disease progression in multiple sclerosis

UCSF researchers have identified a correlation between higher levels of glutamate, which occurs naturally in the brain as a byproduct of metabolism, and greater disease burden in multiple sclerosis patients.

Disruption of copper regulation key to prion diseases

An investigation of a rare, inherited form of Creutzfeldt-Jakob disease suggests that disrupted regulation of copper ions in the brain may be a key factor in this and other prion diseases.

Rockefeller University Hospital opens clinical trial into statin-associated muscle complaints

The most widely prescribed class of drugs in the country, statins have helped millions of people lower their cholesterol and reduce their risk of heart attacks - but their side effects, including muscle pain and cramping, have proven to be something of a sore point for many patients.

New light-based system reveals breast tumor oxygen status

Light directed at a breast tumor through a needle can provide pathologists with biological specifics of the tumor and help oncologists choose treatment options that would be most effective for that individual patient.

Noninvasive optical device monitors brain blood flow and metabolism in stroke victims

A University of Pennsylvania team has completed the first successful demonstration of a noninvasive optical device to monitor cerebral blood flow in patients with acute stroke, a leading cause of disability and death.

New optical technology shows promise in detecting pancreatic cancer

Optical technology developed by a Northwestern University professor of biomedical engineering has been shown to be effective in detecting the presence of pancreatic cancer through analysis of neighboring tissue in the duodenum, according to clinical trial results published in the journal Disease Markers.

Ethnic differences found for fatty liver disease and insulin resistance

A new study suggests that the metabolic response to obesity and insulin resistance, particularly as it pertains to the liver, differs among ethnic groups in the U.S. African-Americans are more resistant to the buildup of fat in the abdominal adipose tissue and liver, and to high triglyceride levels associated with insulin resistance.

Determining risk for pancreatic cancer

In the latest clinical trial for a technique to detect pancreatic cancer, researchers found they could differentiate cells that are cancerous from those that are benign, pre-cancerous, or even early stage indicators called mucinous cystic lesions.

New imaging techniques let scientists see biomolecules more clearly

Scientists have always wanted to take a closer look at biological systems and materials. From the magnifying glass to the electron microscope, they have developed increasingly sophisticated imaging devices.

Life-giving technology: Camera pills and ultrasound creating maps of the body

For more than ten years, senior medical officer Ronald Marvik at St. Olav's Hospital in Trondheim has been collaborating with SINTEF scientist Thomas Lango. Together, they have created a new IT-base window on the inside of the body, a window that makes a patient transparent on a screen when a surgeon inserts operating instruments through small openings in the abdominal wall.

Forgotten and lost -- when proteins 'shut down' our brain

Which modules of the tau protein, in neurons of Alzheimer disease patients, may act in a destructive manner were investigated by researchers from the Max Planck Institute for Biophysical Chemistry (Göttingen) and the Max Planck Unit for Structural Molecular Biology (Hamburg) with the help of Nuclear Magnetic Resonance Spectroscopy ( PLoS Biology , February 17, 2009).
