Forget about duct tape. Just grab the ’gecko glue’
Geckos, nature’s supreme climbers, can race up a polished glass wall at a meter per second and support their entire body weight from a wall with only a single toe. But the gecko’s remarkable climbing ability has remained a mystery since Artistotle first observed it in fourth century B.C.
Now a team of biologists and engineers has cracked the molecular secrets of the gecko’s unsurpassed sticking power–opening the door for e
Treating the skin with caffeine has been shown to prevent skin cancer in laboratory studies conducted in the Susan Lehman Cullman Laboratory for Cancer Research at Rutgers, The State University of New Jersey.
“It is not a sun-screening effect, but its something more than that – its a biological effect,” said Allan Conney, William M. and Myrle W. Garbe Professor of Cancer and Leukemia Research at Rutgers Ernest Mario School of Pharmacy. “We may have found a safe and effecti
Scientists have analyzed the complete genome sequence of an emerging human pathogen, Streptococcus agalactiae (also known as group B streptococcus or “strep B”), which is a leading cause of pneumonia and meningitis in newborns and the source of life-threatening illnesses in a growing number of adults with deficient immune systems.
The study, published this week in the on-line version of the Proceedings of the National Academy of Sciences (PNAS), not only determined the pathogens genet
Extinction rates of native California plants have been studied by three researchers who found that previously designed mathematical and computer models were biased because they left out the human element in their predictions, according to an article published in the August 20 Proceedings of the National Academy of Sciences. They conclude with the key concern that “understanding the relationship between habitat loss and loss of biodiversity is central to the development of sound conservation policy.”
Early Detection of Alzheimers Could Lessen the Impact
Incidence of Alzheimers Disease is expected to increase as the population of elderly grows. Early diagnosis and treatment will be the key to lessening the diseases worst effects, but, how to spot the disease before its symptoms become serious (and harm is already done) is a challenge for health professionals. A new study by psychologists Konstantine K. Zakzanis, Ph.D., and Mark Boulos, B.Sc., of the University of
A comprehensive examination of how the unique head and snout affects maneuverability and the role of its electrosensory function for seeking food along the ocean floor
Why the peculiar head shape of the hammerhead shark developed as it did has been the subject of much speculation. The dorso-ventrally compressed and laterally expanded pre-branchial head is an unmistakable diagnostic feature of the sphyrnid sharks. This unique head shape has been termed the cephalofoil in recognition of
