(Phys.org) —A group of researchers from Sweden have provided further evidence that illegal drugs can be detected in the breath, opening up the possibility of a roadside breathalyzer test to detect substances such as cocaine, ...
An interdisciplinary team has used a new technique known as plasma oxidation to produce radio carbon dates for paint fragments as small as 10 micrograms in width.
(Phys.org) —A unique chemical imaging tool readily and reliably presents volatile liquids to scientific instruments, according to a team including Pacific Northwest National Laboratory. These instruments require samples ...
(Phys.org)—The perennial stress-buster—a deep breath—could become stress-detector, claims a team of researchers from the UK.
When Lawrence Livermore National Laboratory researchers invented the field of biological accelerator mass spectrometry (AMS) in the late 1980s, the process of preparing the samples was time-consuming and cumbersome.
(Phys.org) —If half of a cell population were coloured white and the other half were coloured black, scientists should think all cells are grey. Conventional methods average over thousands of cells, overlooking any cell-to-cell ...
Spindle-shaped inclusions in 3 billion-year-old rocks are microfossils of plankton that probably inhabited the oceans around the globe during that time, according to an international team of researchers.
A cheaper, more efficient technique for developing complex protein drugs from bacteria has been developed at the University of Sheffield.
Researchers at the University of Tennessee, Knoxville, are once again turning what scientists thought they knew about the moon on its head.
(Phys.org)—Scientists have identified the chemical 'fingerprints' given off by specific bacteria when present in the lungs, potentially allowing for a quick and simple breath test to diagnose infections such as tuberculosis.
