Practical approach for assessing the melanin and blood content of the skin

24-Apr-2015

Many factors can change skin pigmentation, including aging, exposure to UV light, certain drugs, as well as certain diseases. A simple technique for measuring skin pigmentation could be a helpful tool for research and diagnostics. The same goes for measuring the skin blood content. Alteration of ...

Scientists X-ray anti-inflammatory drug candidates

Study resolves molecular structures of Spiegelmers for the first time

24-Apr-2015

Using DESY's ultra bright X-ray source PETRA III, scientists have decoded the molecular and three-dimensional structure of two promising drug candidates from the new group of Spiegelmers for the first time. The results provide a deeper understanding of the mode of action of these substances that ...

New tabletop detector 'sees' single electrons

Magnet-based setup may help detect the elusive mass of neutrinos

23-Apr-2015

MIT physicists have developed a new tabletop particle detector that is able to identify single electrons in a radioactive gas.As the gas decays and gives off electrons, the detector uses a magnet to trap them in a magnetic bottle. A radio antenna then picks up very weak signals emitted by the ...

Detecting lung cancer at an early stage

Marker-free, automatic procedure facilitates prognosis regarding tumour aggressiveness

22-Apr-2015

A new diagnostic method, namely spectral histopathology, facilitates marker-free detection of individual subtypes of lung cancers. It was developed by researchers at the PURE consortium at Ruhr-Universität Bochum (RUB). They have successfully applied it in collaboration with clinicians at the ...

DNA blood test detects lung cancer mutations

Circulating tumour DNA in blood a valid option for EGFR testing in patients who do not have accessible tumour tissue, study shows

21-Apr-2015

Cancer DNA circulating in the bloodstream of lung cancer patients can provide doctors with vital mutation information that can help optimise treatment when tumour tissue is not available, an international group of researchers has reported at the European Lung Cancer Conference (ELCC) in Geneva, ...

Picturing peanut contamination with near infrared hyperspectral imaging

07-Apr-2015

Study the label of almost any food product and you’re likely to see the rather vague warning “May contain peanuts” somewhere on there, unless of course it’s a product that definitely does contain peanuts. As now revealed in a paper in JNIRS - Journal of Near Infrared Spectroscopy, these warnings ...
