Biosensor 'bandage' collects and analyzes sweat

Like other biofluids, sweat contains a wealth of information about what's going on inside the body. However, collecting the fluid for analysis, usually by dripping or absorbing it from the skin's surface, can be time-consuming ...

SLAC's high-speed 'electron camera' films molecular movie in HD

With an extremely fast "electron camera" at the Department of Energy's SLAC National Accelerator Laboratory, researchers have made the first high-definition "movie" of ring-shaped molecules breaking open in response to light. ...

Tiny light-up barcodes identify molecules by their twinkling

An imaging technique developed at Duke University could make it possible to peer inside cells and watch dozens of different molecules in action at once—by labeling them with short strands of light-up DNA that blink on and ...

Spinout seeks to transform food safety testing

"This is a $10 billion market and everyone knows it." Those are the words of Chris Hartshorn, CEO of a new MIT spinout—Xibus Systems—that is aiming to make a splash in the food industry with their new food safety sensor.

Researchers discover new technique to test for viral infections

A team of Colorado State University researchers has developed technology that can detect extremely small amounts of antibodies in a person's blood. Antibodies develop to infect cells or kill pathogens, essentially fighting ...

Cathinone color test is now on the market

Every four days, a new illicit synthetic drug enters the world market. These drugs, which are designed to mimic established drugs of abuse, are cheap, often highly toxic, and difficult—if not impossible—to detect using ...

Detecting pollution with a compact laser source

Researchers at EPFL have come up with a new middle infrared light source that can detect greenhouse and other gases, as well as molecules in a person's breath. The compact system, which resembles a tiny suitcase, contains ...

Testing radiation resistance without using a nuclear reactor

The University of Huddersfield's combined electron microscope and ion beam accelerator is a world-class facility responsible for a large and growing global network of research collaborations. One of the latest is a partnership ...

Uncovering the secrets of ancient rock art using 'X-ray vision'

Prehistoric rock paintings are a source of fascination across the world. Aside from their beauty, there's deep meaning in these strokes, which depict ancient rituals and important symbols. To learn more about these murals, ...

Quantum physics and origami for the ultimate get-well card

Paper-based diagnostic tests are cheap, convenient and biodegradable. However, their use is limited by conventional dyes—which are not bright enough to show trace amounts of analyte, are prone to fading, and can be environmentally ...

Solving a hairy forensic problem

For decades, forensic scientists have tested strands of hair to reveal drug use or poisoning. But in recent years, reports have questioned the technique—in particular, its ability to distinguish between the intake of a ...
