Nature's secrets yield new adhesive material
Scientists report they have merged two of nature's most elegant strategies for wet and dry adhesion to produce a synthetic material that one day could lead to more durable and longer-lasting bandages, patches, and surgical materials. view more (2007-07-19)
An elephant tail
By analyzing chemicals in tail hair from elephants that wore radio collars, researchers tracked the diet and movements of elephants in Kenya - a method aimed at reducing human-elephant conflicts and determining where to establish sanctuaries to protect the endangered creatures. view more (2006-01-03)
Weeding out marijuana: Researchers close in on engineering recognizable, drug-free Cannabis plant
In a first step toward engineering a drug-free Cannabis plant for hemp fiber and oil, University of Minnesota researchers have identified genes producing tetrahydrocannabinol (THC), the psychoactive substance in marijuana. Studying the genes could also lead to new and better drugs for pain, nausea and other conditions. view more (2009-09-16)
Origins of wolverine in California genetically verified
A wolverine first photographed by a remote-controlled camera on the Tahoe National Forest in February 2008 is most closely related to Rocky Mountain populations, according to a team of 10 federal, state and university scientists. view more (2009-04-30)
Regulator of lipid metabolism ensures high quality breast milk
Mouse mammary glands deficient in PPARg a nuclear receptor that regulates the storage of fat, produce toxic milk that causes inflammation and baldness in suckling pups, report scientists at the Salk Institute for Biological Studies. view more (2007-08-15)
Bats Use Touch Receptors on Wings to Fly, Catch Prey, Study Finds
Bats have an "ear" for flying in the dark because of a remarkable auditory talent that allows them to determine their physical environment by listening to echoes. But an Ohio University neurobiology professor says bats have a "feel" for it, too. view more (2005-12-16)
Thin is beautiful - Zulu men now prefer Western-looking women
Black South African women have once more been flagged up as being on the brink of an eating disorder crisis, as the latest research reveals that their male counterparts, who once idolised fuller-figured females, now prefer thinner, Western-looking women. view more (2004-08-31)
Scat sniffing dogs detecting rare California carnivores
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)
Researchers ID traits of people with rare accelerated aging syndrome
UT Southwestern Medical Center researchers have provided the most extensive account to date of the unique observable characteristics seen in patients with an extremely rare premature aging syndrome. view more (2009-12-15)
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)
