Infants sighs may 'reset' breathing regulation mechanism as well as help lungs develop

... ... ... ...BETHESDA, MD (August 12, 2004) As if new parents don't have enough to worry about getting in synch with their infants, many of them wonder "what's with these sighs?"... ...Of course adults sigh; not as often as infants, though sometimes often enough to annoy others. But with an adult, you can ask if there's a problem. With newborns, it's hard to know if it's good...

The Hunter's Breath tells a story of adventure and discovery in Antarctica

SANTA CRUZ, CA--In six trips to Antarctica, biologist Terrie Williams endured brutal conditions on the coldest, driest, windiest continent on Earth in order to learn the secrets of the mysterious Weddell seals, the only wild mammals capable of surviving Antarctic winters.

Bird 'breathalyzer' helps assess migratory diet

KINGSTON, R.I. -- November 24, 2003 -- While breathalyzers help police crack down on drunk driving, a similar new device is helping a University of Rhode Island graduate student analyze the dietary changes of migrating songbirds. ... Just as human breathalyzers measure an individual's blood-alcohol level, David Podlesak says that his bird breathalyzer measures the "carbon signature" of a bird's l...

Ultra-low oxygen could have triggered die-offs, spurred bird breathing system

Recent evidence suggests that oxygen levels were suppressed worldwide 175 million to 275 million years ago and fell to precipitously low levels compared with today's atmosphere, low enough to make breathing the air at sea level feel like respiration at high altitude.... ... Now, a University of Washington paleontologist theorizes that low oxygen and repeated short but substantial temperature incr...

Nasal contribution to breathing with exercise: The effect of race and gender

(Bethesda, MD) The mode of breathing -- via the mouth (oral) or the nose (nasal) -- is an important determinant of a deposited dose of inhaled particles and gases to the lungs. The nose can act as an effective filter to prevent penetration of particles and gases to the lower respiratory tract. Gases that are very water soluble or reactive (such as ozone) can be extracted in the nose by as much...

UCLA neurobiologists identify brain cells that control breathing

For the first time, UCLA scientists have identified the small group of brain cells believed to originate breathing in mammals. Reported in the September issue of Nature Neuroscience, their discovery could lead researchers to new approaches to addressing serious health problems, such as sleep apnea and sudden infant death syndrome....... In a previous study, the UCLA team had pinpointed a specifi...

Study: breath test effective in showing patients who should get less cancer drug

. . Battling cancer is traumatic enough without worrying about whether chemotherapy will prove toxic, but that's the added risk facing a minority of cancer patients.. Standard doses of chemotherapy -- often effective in treating various solid tumors -- sometimes kill people whose livers cannot clear the drug at the normal rate. Doctors can't tell beforehand which patients might have trouble wi...

Studies of marine mammals indicate a "breathtaking" ability to dive to great depths
