Team first to blend high-end imaging techniques

Vanderbilt University researchers have achieved the first "image fusion" of mass spectrometry and microscopy—a technical tour de force that could, among other things, dramatically improve the diagnosis and treatment of ...

Researchers explore fading red in Van Gogh art

While debate over whether a dress was blue and black or white and gold has caused an Internet storm of talk about color, discussions in scientific circles raise questions about red, asking why are Van Gogh's reds turning ...

Potential new breathalyzer for lung cancer screening

Researchers from Chongqing University in China have developed a high sensitive fluorescence-based sensor device that can rapidly identify cancer related volatile organic compounds—biomarkers found exclusively in the exhaled ...

Lab-on-a-chip to study single cells

Scientists at EPFL have developed a new lab-on-a-chip technique to analyze single cells from entire population. The new method, which uses beads and microfluidics can change the way we study mixed populations of cells, such ...

How does a machine smell? Better than it did

Every odor has its own specific pattern which our noses are able to identify. Using a combination of proteins coupled to transistors, for the first time machines are able to differentiate smells that are mirror images of ...

Team enlarges brain samples, making them easier to image

Beginning with the invention of the first microscope in the late 1500s, scientists have been trying to peer into preserved cells and tissues with ever-greater magnification. The latest generation of so-called "super-resolution" ...

Key to longevity of imperial Roman monuments

No visit to Rome is complete without a visit to the Pantheon, Trajan's Markets, the Colosseum, or the other spectacular examples of ancient Roman concrete monuments that have stood the test of time and the elements for nearly ...
