Saving Rembrandt for future generations

The surface of many Old Master paintings has been affected by the appearance of whitish lead-rich deposits, which are often difficult to fully characterise, thereby hindering conservation. Painted in 1663, Rembrandt's Homer ...

Lab-on-a-chip helps search for human DNA at crime scenes

Thanks to the work carried out by University of Twente Ph.D. candidate Brigitte Bruijns, crime scenes can now be inspected on the spot for the presence of human DNA. In her Ph.D. thesis, she describes a lab-on-a-chip that ...

Experts push the boundaries of 3-D microscopy

Two newly developed methods will help researchers to study the 3-D structure of complex surfaces and of individual neurons better than ever before. Sebastian Munck and Natalia Gunko, two expert technologists at VIB-KU Leuven, ...

3-D culturing hepatocytes on a liver-on-a-chip device

Liver-on-a-chip cell culture devices are attractive biomimetic models in drug discovery, toxicology and tissue engineering research. To maintain specific liver cell functions on a chip in the lab, adequate cell types and ...

Coming soon: A blood test for Alzheimer's disease?

People with symptoms of Alzheimer's disease (AD), such as cognitive difficulties, behavior changes and mood swings, may wait months or even years to get a definitive diagnosis. That's because doctors lack a simple, accurate ...

Novel viral identification method developed

Currently, influenza typing in clinical practice is performed using an immunochromatography method based on antigen-antibody interaction. This method enables simple diagnosis of infectious diseases. However, it also has a ...

The secret to Rembrandt's impasto unveiled

Impasto is thick paint laid on the canvas in an amount that makes it stand from the surface. The relief of impasto increases the perceptibility of the paint by increasing its light-reflecting textural properties. Scientists ...

Research finds serious problems with forensic software

New research from North Carolina State University and the University of South Florida finds significant flaws in recently released forensic software designed to assess the age of individuals based on their skeletal remains. ...

Chirality in real time

Distinguishing between left-handed and right-handed (chiral) molecules is crucial in chemistry and the life sciences, and is commonly achieved using a method called circular dichroism. However, during biochemical reactions, ...

How dangerous is microplastic?

After alarming reports of microplastic pollution in oceans and beaches, the global scientific community intensified its focus into this area. Researchers have since found evidence of microplastic contamination everywhere—in ...

New dynamic probes for ions interacting with biomolecules

Pairs of negatively charged phosphate groups and positive magnesium ions represent a key structural feature of DNA and RNA embedded in water. Vibrations of phosphate groups have now been established as selective probes of ...

Mobile, instant diagnosis of viruses

In a first for plant virology, a team from CIRAD recently used nanopore technology to sequence the entire genomes of two yam RNA viruses. This little-used but promising molecular biology technique paves the way for new tools ...

New tool could treat blood infections quickly

Bloodstream infections are notoriously deadly. Not because they're untreatable, but because they work fast and are hard to diagnose. To figure out what medication to give patients, doctors need to culture the bacteria or ...
