Get a whiff of this: Smell test could sniff out serious health problems

...cannot detect odor, the size of the sniff for just air and the size of the sniff for an odor are the same.? In humans, Frank says the sense of smell is one of our less robust senses. He says it’s more susceptible to harm because there is less neurological machinery in the brain devoted to processing th...

Better health twice as likely for nonsmokers who live and work with smoking restrictions

...he adoption of smoke-free homes, and as smoke-free air legislation spreads, a rise in protection from secondhand smoke at home can be expected. "However, this does not, preclude the need to take a proactive approach to increasing adoption of household bans," says Dr. Shelley. The study suggests that...

Spreading viruses as we breathe

... way droplets carring viruses are dispersed in the air when people speak, cough, sneeze and breathe. "...e to measure the distance a droplet travels in the air prior to drying. "This droplet could potentially be carrying a virus," she said. "The signific...

Dinosaur hearing, listening to muscle noise, quieter cubicles

...ile of a wind instrument's bore, the chamber where air vibrates and produces pitch. Wilfried Kausel of the University of Music and Performing Arts in Austria ( kausel@mdw.ac.at ) will present growing experimental evidence that wall vibrations and thickness are important (4pMU2). REDUCING NOISE IN ...

8 plants from South Africa may hold potential for treating high blood pressure

...subsequently filtered and the filtrate was left to air dry resulting in the specific test compound. ACE activity was determined using a flourimetric method with Hip-His-Leu as a substrate. The fluorescence of the o-phthaldialdehyde was measured to determine the effect of the plant on ACE activity. Pla...

Maggots rid patients of MRSA

...sings and the biogun treatment, which uses ionized air to create superoxide radicals and eradicate bacteria. Professor Boulton said: "This is very exciting. We have demonstrated for the first time the potential of larval therapy to eliminate MRSA infection of diabetic foot ulcers. If confirmed in a ra...

'Virtual Patient' to simulate real-time organ motions for radiation therapy

...consider such issues as the breathing function and air volume change that are affected by several physiological factors over the course of the radiation treatment." Real-time simulations could allow doctors to spot the small fractions of time when the lungs, liver, kidneys, and eventually the heart, a...

New research shows sharks use their noses and bodies to locate smells

...arch team, this is similar to how humans can sense air flow with the small hairs on the face. Until now, it had not been demonstrated that the lateral line also aids in the tracking of odor plumes. "Odor plumes are complex, dynamic, three-dimensional structures used by many animal species to locate foo...

Smoking rate has plummeted in New York City

...n they’re paired with a tobacco tax and smoke-free air legislation. With nearly a quarter of a million fewer smokers, New York City is leading the way on tobacco control. There aren’t many programs that can prevent 80,000 premature deaths this quickly.” Ads from the 2006 campaign graphically depicte...

Scientists close in on missing carbon sink

Researchers examine carbon capture and storage to combat global warming

...comes even more crucial, Benson said. From the air to the earth In the capture process, carbon dioxide is extracted from a mix of waste gases. The most common method sends the exhaust through a chimney containing a three-dimensional mesh. As the gas goes up, a chemical solvent drizzles down, soak...

Longer treatment benefits sleep apnea patients

...he patient sleeps and works by blowing just enough air into the nose to keep the patient's throat open. Because they often find the CPAP device cumbersome, many patients do not use it consistently or for long enough periods while sleeping. In the current study, for example, patients used CPAP on ave...

Cigarette smoke alters DNA in sperm, genetic damage could pass to offspring

...iation, mutagenic chemicals and intense industrial air particulate pollution. While the researchers did not specifically study the protein-coding regions of DNA where genes reside, Yauk notes that previous studies correlate mutations in non-coding regions with those in coding regions, and that some repet...
