New optical method paves way to breath test for cancer biomarker

Researchers have developed an extremely sensitive, yet simple optical method for detecting formaldehyde in a person's breath. Because formaldehyde is being studied as a potential biomarker for lung and breast cancer, the ...

Reliably measuring whether rivers or lakes run out of air

Wastewater carries large quantities of organic substances into the rivers and lakes, leading to heavy growth of bacteria and oxygen deficiency. Measurement methods have so far been incapable of measuring this organic pollution ...

New discovery improves use of optical tweezers

This year's Nobel Prize in Physics, awarded for discoveries in laser physics, recognizes optical tweezers. Now researchers from the University of Gothenburg have developed a method that greatly simplifies and improves the ...

Tiny, super cold atoms and the Earth's remaining oil sources

Ground-breaking space exploration technology is being used to develop an innovative new sensor for the subsea industry. Dr Charles Wang, an astrophysicist at the University of Aberdeen who is leading the development of the ...

Water isotopes leave fingerprints for climate scientists

University of Colorado meteorologist David Noone and his team are working to understand how water moves around the planet. With support from the National Science Foundation (NSF), the project team observes and analyzes the ...

Getting more information by measuring faster and averaging less

For signals barely larger than the noise in a system, measurement is generally a trade-off between speed and precision. Averaging over several measurements reduces the influence of noise but takes (a lot of) time. That could ...
