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

'MasSpec Pen' could help distinguish between cancerous and healthy tissue during surgery

A major challenge for cancer surgeons is to determine exactly where a tumor starts and where it ends. Removing too much tissue can impair normal functions, but not taking enough can mean the disease could recur.

Researchers analyze precise mechanism of binding reaction in PUVA therapy

The term 'PUVA' stands for 'psoralen' and 'UV-A radiation'. Psoralens are natural plant-based compounds that can be extracted from umbelliferous plants such as giant hogweeds.

Liver dysfunction provokes cerebral molecular disturbances in two weeks

The liver plays a vital role as a filter in the human body. But what happens when it malfunctions? Researchers from the Universities of Geneva and Lausanne, the Vaud University Hospital Centre, the Centre for Biomedical Imaging, the Federal Polytechnic School of Lausanne and the University Hospitals of Geneva, Switzerland, teamed up to perform a detailed analysis of hepatic encephalopathy, a type of brain damage caused by chronic liver disease.

Molecular mechanism of enterovirus infection uncovered

Researchers from the Nanoscience Center at the University of Jyväskylä in collaboration with those at the University of Helsinki have found that body proteins called albumin and certain ions within the attacked host cells can affect the genetic workings of enteroviruses and enhance their infection.

Beta amyloid structure mapped in new Alzheimer’s research

In search of a possible cure for Alzheimer’s disease (AD), scientists have found out the molecular structure of a type of protein called beta amyloid that accumulates within brain cells, eventually killing them. This could help understand how to prevent these abnormal proteins from forming, leading to a cure or treatment for this killer disease.
