Scientists at the U.S. Forest Service Redwood Sciences Lab and University of Vermont found scat sniffing dogs might be the best way to confirm the presence of rare carnivores in forested areas like the Southern Sierra Nevada Mountains. view more (2007-12-12)
Protein tied to usher syndrome may be hearing's 'Missing Link'
A protein associated with a disorder that causes deafness and blindness in people may be a key to unraveling one of the foremost mysteries of how we hear. view more (2006-06-28)
Airway cells use 'tasting' mechanism to detect and clear harmful substances
The same mechanism that helps you detect bad-tasting and potentially poisonous foods may also play a role in protecting your airway from harmful substances, according to a study by scientists at the University of Iowa Roy J. and Lucille A. Carver College of Medicine. view more (2009-07-27)
Scripps Research scientists reveal pivotal hearing structure
In a study published in the September 6, 2007, issue of the journal Nature, researchers showed that two key proteins join together at the precise location where energy of motion is turned into electrical impulses. view more (2007-09-06)
A Newtonian system that mimics the baldness of rotating black holes
The rotating black hole has been described as one of nature's most perfect objects. view more (2009-02-24)
Reduced mitochondrial function important mechanism in aging
Scientists at the Karolinska Institute have found that changes in the "powerhouse" of cells, the mitochondria, play a key role in aging. The findings are being published in this week's issue of the journal Nature. Mitochondria, which provide energy to cells, have their own set of DNA. Mutations of mitochondrial DNA increase with age,... view more... (2004-05-27)
'Escaped' proteins add to hearing loss in elderly, UF researchers find
Age-related hearing loss is the most common sensory disorder among the elderly. But scientists are still trying to figure out what cellular processes govern or contribute to the loss. view more (2009-11-11)
Penn Engineers Create Carbon Nanopipettes That Are Smaller Than Cells and Measure Electric Current
University of Pennsylvania engineers and physicians have developed a carbon nanopipette thousands of times thinner than a human hair that measures electric current and delivers fluids into cells. view more (2008-01-16)
Long-term bouts with hay fever worsen ability to breathe through your nose
New evidence for the first time suggests that people suffering from hay fever (allergic rhinitis) will over time experience a progressive worsening of their nasal passage functioning, depending on how long they have the disorder, according to a new study published in the June 2008 edition of Otolaryngology - Head and Neck Surgery. view more (2008-06-02)
Mice cloned from skin cells
Healthy and viable mice that survive until adulthood have, for the first time, been cloned from adult stem cells. Scientists from Rockefeller University, including Howard Hughes Medical Institute investigator Elaine Fuchs, used cells called keratinocyte stem cells, which represent a new model system for cloning. view more (2007-02-13)
Scientists believe photograph depicts wolverine in California
U.S. Forest Service scientists believe an Oregon State University graduate student working on a cooperative project with the agency's Pacific Southwest Research station on the Tahoe National Forest has photographed a wolverine, an animal whose presence has not been confirmed in California since the 1920s. view more (2008-03-10)
Stem-cell transplantation improves muscles in MD animal model, UT Southwestern researchers report
Using embryonic stem cells from mice, UT Southwestern Medical Center researchers have prompted the growth of healthy - and more importantly, functioning - muscle cells in mice afflicted with a human model of Duchenne muscular dystrophy. view more (2008-01-21)
How nonstick bugs evade natural fly paper
There are few things more irritating than a fly buzzing around the house. South Africans have an unconventional solution to the problem. view more (2008-08-11)
Go Speed Racer! Revving up the world's fastest nanomotors
In a "major step" toward a practical energy source for powering tomorrow's nanomachines, researchers in Arizona report development of a new generation of sub-microscopic nanomotors that are up to 10 times more powerful than existing motors. Their study is scheduled for the May 27 issue of ACS Nano, a monthly journal. view more (2008-05-01)
Spiders make best ever Post-it notes
Scientists have found that the way spiders stick to ceilings could be the key to making Post-it® notes that don't fall off - even when they are wet. A team from Germany and Switzerland have made the first detailed examinations of a jumping spider's 'foot' and have discovered that a molecular force sticks the spider to almost anything. The... view more... (2004-04-15)
Adolescents, risks and the pitfalls of rationality
Is it a good idea to swim with sharks? Is it smart to drink a bottle of Drano? What about setting your hair on fire - is that a good thing to do? view more (2006-11-14)
Women dress as a life-cycle symbol
An infant becomes a girl, then a young lady, a woman and, at last, becomes old. It is just the common life cycle of any female human being and nothing can change it. From time immemorial our ancestors would dress in the pieces of clothing corresponding to each age. Historian Darima Nikolaeva at the East-Siberian State Academy of Culture and Arts... view more...

Hopkins develops online tool to aid research on certain 'orphan diseases'
Many people are afflicted with rare illnesses of unknown cause, and finding a common link to such under-studied or "orphaned" diseases as Bardet-Biedl, Alstrom and Meckel-Gruber syndromes can significantly advance the search for causes and treatment. view more (2006-08-29)
Toward a nanomedicine for brain cancer
In an advance toward better treatments for the most serious form of brain cancer, scientists in Illinois are reporting development of the first nanoparticles that seek out and destroy brain cancer cells without damaging nearby healthy cells. view more (2009-09-10)
New iPod listening study shows surprising behavior of teens
A new study involving iPods and teenagers by the University of Colorado at Boulder and Children's Hospital Boston indicates teenagers who receive pressure from their peers or others to turn down the volume of their iPods instead turn them up higher. view more (2009-02-19)
