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

Northwestern University move closer to new therapies for neurodegenerative disease

French neurologist Jean-Martin Charcot first described amyotrophic lateral sclerosis (ALS) in 1869, but, nearly 140 years later, little is known about the cause of the devastating neurodegenerative disease, and there is no cure.

New device offers potential for accurate and reliable monitoring of brain oxygenation during cardiac surgeries

A new device that uses near-infrared light to non-invasively monitor the oxygenation of the brain during surgery appears to be a promising alternative to the more invasive techniques currently in use, according to a new study by Duke University Medical Center anesthesiologists.

Fijiian seaweed shows potential to kill cancer cells, bacteria and the HIV virus

Researchers have discovered 10 new molecular structures with pharmaceutical potential in a species of red seaweed that lives in the shallow coral reef along the coastline of Fiji in the south Pacific Ocean.

Glucose test device for diabetics that does not involve pricking the finger

A Syracuse University chemistry professor has patented a device that aims to make painful fingerstick testing of glucose levels a thing of the past for diabetics.

Researchers have successfully combined computer modeling and experimental results in folding studies for small proteins

In unprecedented new research, scientists at Rice University have combined theory and experiment for the first time to both predict theoretically and verify experimentally the protein-folding dynamics of a large, complex protein.

Scientists measure with unprecedented accuracy the strengths of hydrogen bonds in a protein

The scientists were then able to predict the function of different versions of the protein based on structural information, a novel outcome that was published recently in the Proceedings of the National Academy of Sciences.

Salicylate an active metabolite of aspirin - weakens lipid membranes

It's well known that high doses of aspirin can cause ulcers and temporary deafness, but the biochemical mechanism responsible for these phenomena has never been deciphered.

A quirky or socially awkward approach to life might be the key to becoming a great artist, composer or inventor

New research in individuals with schizotypal personalities - people characterized by odd behavior and language but who are not psychotic or schizophrenic - offers the first neurological evidence that these individuals are more creative than normal or fully schizophrenic people, and rely more heavily on the right sides of their brains than the general population to access their creativity.

Mushrooms are a great source of antioxidants

Using a new, more sensitive-testing approach they developed for fungi, Penn State food scientists have found that mushrooms are a better natural source of the antioxidant ergothioneine than either of the two dietary sources previously believed to be best

Fluorescence spectroscopy able to detect the presence of inflammatory cells that are associated with critical atherosclerotic plaques

Because atherosclerotic plaque typically builds up without symptoms and leads to more than 1 million deaths in America each year, the search is on to develop early detection devices that will enable physicians to offer treatment before the disease progresses to advanced stages.

Researchers reveal secret of key protein in brain and heart function

Brown University biologists have solved the structure of a critical piece of synapse-associated protein 97 (SAP97) found in abundance in the heart and head, where it is believed to play a role in everything from cardiac contractions to memory creation. Results are published in The Journal of Biological Chemistry.

New way to prevent macular degeneration

Two studies from an unusual research partnership at the University of Chicago appear to have resolved a long-standing dispute about the role of melanin in the eye. The studies, one published in the Proceedings of the National Academy of Sciences (PNAS) and one early online in the Journal of the American Chemical Society (JACS), also suggest a new way to prevent a common cause of blindness.

Adding spectroscopy to breast MR examinations may improve the efficiency and quality of patient care

Measuring the biochemical changes in breast tumors with magnetic resonance (MR) spectroscopy enables radiologists to more accurately distinguish benign tumors from cancerous ones, according to a study appearing in the August issue of the journal Radiology.

New insights into brain cell metabolism from PET and MRI scans

By discovering a crucial piece of submicroscopic information about how the brain converts fuel into energy for neurons, Cornell University biophysicists have gleaned new insights into brain cell metabolism that will allow neurologists to better interpret data from such diagnostic tests as positron emission tomography (PET) scans and a specialized magnetic resonance imaging (MRI) test.

Forensic use of tandem mass-spectroscopy detects links between banknotes and drugs

Research published in this month’s edition of the journal Rapid Communications in Mass Spectrometry, describes a method that can detect a pattern of contamination on banknotes from drug related crime that is different from the pattern seen in general circulation. The process is significantly faster than other previous methods.

Brain differences in bipolar disorder shown in MRI

Experts in the U.S., in an attempt to define the abnormalities in the brains of people with bipolar disorder, have used used functional MRI to measure levels of metabolic activity in different areas of the brain.

Studies show Alzheimer's prevented by drinking juice daily and having the occasional alcoholic drink

At a conference in the U.S. on Alzheimer's disease on June 19, researchers said that they think brain scans and simple blood tests may offer the best ways to predict who has the highest risk of Alzheimer's disease.

The bacteria that cause food poisoning, bubonic plague, and whooping cough all deploy the same weapon to infect the body

A molecular "syringe" sticks out of the bacteria, pokes a hole in a nearby cell, and squirts in venomous proteins that hijack the cell's machinery.

Fluorescence device to diagnose atherosclerosis and tumors

In a presentation at the Conference on Lasers and Electro-Optics (CLEO), researchers from Cedars-Sinai Medical Center's Biophotonics Research and Technology Development Laboratory described recent progress on a device that stimulates, collects and measures light emissions from body tissues to diagnose critical atherosclerotic plaques (vulnerable plaques) and aggressive brain tumors.

Severely obese children have lipoprotein profiles that signal early risk of cardiovascular disease and the metabolic syndrome

"The message is urgent about the importance of prevention of cardiovascular disease in childhood. Lifestyle modification with appropriate diet and exercise can reduce cardiovascular risk in children," said lead author Daniel L. Preud'Homme, M.D., associate professor of medicine at the Wright State University School of Medicine and director of the lipid clinic at The Children's Medical Center, both in Dayton, Ohio.
