Turkeys inspire smartphone-capable early warning system for toxins
(Phys.org) —Some may think of turkeys as good for just lunch meat and holiday meals. But bioengineers at the University of California, Berkeley, saw inspiration in the big birds for a new type of biosensor ...
Researchers devise a way to measure volatile organic compound exchange in the atmosphere
Electronic nose prototype may be worn for safety-sniffing
Forest emissions, wildfires explain why ancient Earth was so hot
(Phys.org) —The release of volatile organic compounds from Earth's forests and smoke from wildfires 3 million years ago had a far greater impact on global warming than ancient atmospheric levels of carbon ...
Two-stroke scooters are 'super-polluters', study finds
Scientists on Tuesday pointed the finger at two-stroke scooters, a ubiquitous sight in developing countries, for massively contributing to local air pollution.
New gas-phase compounds form organic particle ingredients
Helsinki/Jülich/Leipzig. Scientists made an important step in order to better understand the relationships between vegetation and climate. So-called extremely low-volatility organic compounds, which are ...
Organic vapors affect clouds leading to previously unidentified climate cooling
University of Manchester scientists, writing in the journal Nature Geoscience, have shown that natural emissions and manmade pollutants can both have an unexpected cooling effect on the world's climate by mak ...
Breath test identifies bacteria's fingerprint
(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.
Ozone masks plant's volatiles, plant eating insects confused
(Phys.org) —Increases in ground-level ozone, especially in rural areas, may interfere not only with predator insects finding host plants, but also with pollinators finding flowers, according to researchers from Penn State ...
Scientists utilise breath and sweat to detect trapped humans
Molecules in their breath, sweat and skin have been used to detect humans in a simulation of a collapsed building, raising the prospect of portable sensors for use in real-life situations, such as the devastating aftermath ...
Elusive atmospheric compound revealed in the laboratory
(Phys.org)—Like a talented escape artist, this atmospheric performer has managed to hide its modus operandi—until now. Scientists at Pacific Northwest National Laboratory and the University of California-San ...
'Self-cleaning' pollution-control technology could do more harm than good, study suggests
Research by Indiana University environmental scientists shows that air-pollution-removal technology used in "self-cleaning" paints and building surfaces may actually cause more problems than they solve.
Harnessing plant-invading fungi for fuel
(Phys.org)—As gas prices rise around the world, researchers are seeking a potential solution from endophytic fungi—fungi that live inside plants.
Life of city buildings can be reduced by trees and plants
Green spaces in towns and cities need extra consideration as they may be damaging buildings in the area, according to new research from the Universities of Southampton and Surrey.
