Scientists pack a lab into a pill, using an idea inspired by breath-freshening strips
(Phys.org) —Inspiration can come in many forms, but this one truly was a breath of fresh air. A group of McMaster researchers has solved the problem of cumbersome, expensive and painfully slow water-testing ...
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.
Evidence that land animals evolved the ability to breathe air as ancient fish
(Phys.org) —In a major evolutionary discovery, Flinders University palaeontologist Professor John Long (pictured) has found evidence to show that four-legged animals first developed the ability to breathe ...
Random Breath Test tactics fail to deter drunk drivers
Western Australia's random breath testing strategy may be capturing more drink-drivers but not deterring drink-driving behaviour for the community.
Eating nuts caused tooth decay in hunter-gatherers
Eating nuts and acorns may have helped hunter-gatherers survive 15,000 years ago in northern Africa but the practice wreaked havoc on their teeth, researchers said Monday.
The mystery of lizard breath: One-way airflow may be 270 million years old
Air flows mostly in a one-way loop through the lungs of monitor lizards – a breathing method shared by birds, alligators and presumably dinosaurs, according to a new University of Utah study.
Scientists confirm functionality of emergency ventilation system for horses
Respiratory or cardiovascular arrest in outdoor animals poses a huge challenge to veterinarians. Ventilation equipment is generally hard to operate and requires electricity and compressed air. Anaesthesiologists ...
