Squeezed light produced using silicon micromechanical system

One of the many counterintuitive and bizarre insights of quantum mechanics is that even in a vacuum—what many of us think of as an empty void—all is not completely still. Low levels of noise, known as quantum fluctuations, ...

New antimatter method to provide 'a major experimental advantage'

(Phys.org)—Researchers have proposed a method for cooling trapped antihydrogen which they believe could provide 'a major experimental advantage' and help to map the mysterious properties of antimatter that have to date ...

Your vital signs, on camera

You can check a person’s vital signs -- pulse, respiration and blood pressure -- manually or by attaching sensors to the body. But a student in the Harvard-MIT Health Sciences and Technology program is working on a system ...

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 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 ...
