Arsenic-breathing life discovered in the tropical Pacific Ocean

Arsenic is a deadly poison for most living things, but new research shows that microorganisms are breathing arsenic in a large area of the Pacific Ocean. A University of Washington team has discovered that an ancient survival ...

Nanoarray sniffs out and distinguishes multiple diseases

Before modern medical lab techniques became available, doctors diagnosed some diseases by smelling a patient's breath. Scientists have been working for years to develop analytical instruments that can mimic this sniff-and-diagnose ...

Measuring the airborne toxicants urban bicyclists inhale

By switching from four wheels to two, bicyclists help reduce traffic and air pollution—all while getting much-needed exercise. But that health benefit could be costly, due to exposure to potentially harmful compounds in ...

Sniffing out cancer with improved 'electronic nose' sensors

Scientists have been exploring new ways to "smell" signs of cancer by analyzing what's in patients' breath. In ACS' journal Nano Letters, one team now reports new progress toward this goal. The researchers have developed ...

Sweet-smelling breath to help diabetes diagnosis in children

The potential to quickly diagnose children with type 1 diabetes before the onset of serious illness could be achieved using a simple, non-invasive breath test, according to new research published today.

Nanomechanical sensors detect cancer from breath

An array of functionalised membrane-type surface stress sensors (MSS) distinguishes cancer patients from healthy people through a signature response to breath samples.

Breath study brings roadside drug testing closer

(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, ...
