Where the first Americans came from, when they arrived and how they got here is as lively a debate as ever, only most of the research to date has focused on dry land excavations. But, last summer's pivotal underwater exploration in the Gulf of Mexico led by Mercyhurst College archaeologist Dr.
U.S. municipal governments are showing leadership by voluntarily accounting for and reducing greenhouse gas emissions resulting from their operations. They also recognize the huge potential to influence long-term reductions from the residents and businesses in their communities, according to a new report.
PHILADELPHIA - Understanding the molecular signals that guide early cells in the embryo to develop into different organs provides insight into ways that tissues regenerate and how stem cells can be used for new therapies.
More pieces in the complex autism inheritance puzzle are emerging in the latest study from a research team including geneticists from The Children's Hospital of Philadelphia, the University of Pennsylvania School of Medicine and several collaborating institutions.
Pediatric researchers have identified hundreds of gene variations that occur more frequently in children with attention-deficit hyperactivity disorder (ADHD) than in children without ADHD. Many of those genes were already known to be important for learning, behavior, brain function and neurodevelopment, but had not been previously associated with ADHD.
The recent explosion in the development of nanomaterials with enhanced performance characteristics for use in commercial and medical applications has increased the likelihood of people coming into direct contact with these materials.

CORVALLIS, Ore. -- A study by Oregon State University researchers suggests that school-based prevention programs begun in elementary school can significantly reduce problem behaviors in students.
For the first time, Cornell researchers have reported the sighting of the emerald ash borer – an ash-destroying beetle – in New York state.
“The threat is extreme,” said E. Richard Hoebeke, a senior extension associate in entomology at Cornell. “There is the potential for ash as we know it to be extirpated from the landscape.”
Two new studies from The Children's Hospital of Philadelphia advance the search for genetic events that result in neuroblastoma, a puzzling, often-deadly type of childhood cancer.
Originating in the peripheral nervous system, neuroblastoma is the most common solid cancer of early childhood and causes 15 percent of all childhood cancer deaths.
PHILADELPHIA -- How molecules of the oldest branch of the human immune system have interconnected has remained a mystery. Now, two new structures, both involving a central component of an enzyme important to the complement system of the immune response, reveal how this system fights invading microbes while avoiding problems of the body attacking itself.
PITTSBURGH -- Researchers at Carnegie Mellon University's School of Computer Science have developed two new tools to help computer programmers select from among thousands of options within the application programming interfaces (APIs) that are used to write applications in Java, today's most popular programming language.
The tools -- Jadeite (
PITTSBURGH -- A group of researchers led by Carnegie Mellon University Biological Sciences Professor Aaron Mitchell has identified a novel regulatory gene network that plays an important role in the spread of common, and sometimes deadly, yeast infections.
PITTSBURGH -- Gene regulatory networks in cell nuclei are similar to cloud computing networks, such as Google or Yahoo!, researchers report today in the online journal Molecular Systems Biology. The similarity is that each system keeps working despite the failure of individual components, whether they are master genes or computer processors.
PHILADELPHIA - -- Psychologists at the University of Pennsylvania have identified a cognitive shortcut, or heuristic, they call "Unit Bias," which causes people to ignore vital, obvious information in their decision-making process, points to a fundamental flaw in the modern, evolved mind and may also play a role in the American population's 30 years of weight gain.
