Penn State engineers have developed a prototype for an ultrasound insulin delivery system that is about the size and weight of a matchbook that can be worn as a patch on the body.
Dr. Nadine Barrie Smith, assistant professor of bioengineering, says, “The new Penn State ultrasound patch, which operates in the same frequency range as the large commercially available sonic drug delivery devices, is about an inch-and-a-half by an inch-and-a-half in size and weighs less than an ounce. Commerciall
A high-throughput assay developed by University of Illinois at Chicago chemists has led to discovery of a small organic compound that shows the unusual ability to inhibit cell migration. The new compound, identified as UIC-1005, may play a role in developing new kinds of cancer drugs.
The findings are published in the November issue of the journal ChemBioChem.
“Weve been looking for chemical compounds that slow the process of cell migration,” said Gabriel Fenteany, assistant
UCLA Neuropsychiatric Institute researchers have localized a region on chromosome 16 that is likely to contain a risk gene for Attention Deficit Hyperactivity Disorder, the most prevalent childhood-onset psychiatric disorder.
Their research, published in the October edition of the American Journal of Human Genetics, suggests that the suspected risk gene may contribute as much as 30 percent of the underlying genetic cause of ADHD and may also be involved in a separate childhood onset disorder
A study by two North Carolina State University geneticists traces the origin and evolution of a genetic mutation that long ago led to the creation of a type of rice known as glutinous, or “sticky,” rice.
The molecular genetic research leads researchers to believe that glutinous rice – which differs from non-glutinous, or common, rice on account of a mutation in its Waxy gene that suppresses the formation of a starch called amylose – most likely originated a single time in Southeast Asia. Fu
But scientists say human effects can be a positive, not negative, factor for life on earth
Human beings now directly influence more than three quarters of the earths landmass, according to a state-of-the-art map of the world produced by a team of scientists from the New York-based Wildlife Conservation Society (WCS) and Columbia Universitys Center for International Earth Science Information Network (CIESIN). Published in the latest issue of the scientific journal BioScienc
During the second century B.C., a mummy-maker took a scroll of poetry and used it as stuffing for a corpse. The roll of papyrus remained hidden inside the mummy’s chest cavity until its rediscovery in the early 1990s. Today, what was once treated like trash survives as the oldest surviving example of a Greek poetry book, as well as an important source of information about the past.
To glean as many clues from this ancient scroll as possible, the University of Cincinnati Department of Class
