Companies wanting to use the Internet to recruit new employees should spotlight the geographic location of positions on their Web sites and include terms used by searchers, rather than site designers or human resource professionals, say Penn State researchers.
“Users’ primary interest when looking for jobs is location, but company Web sites typically don’t highlight geographical information,” said Jim Jansen, assistant professor of information sciences and technology. “Lo
UHC study indicates need for new standards and training
Improving the training and standardizing the procedures used by the nation’s eye banks to assess corneal cells may help to select corneas with optimal health for transplantation, according to new study led by Jonathan H. Lass, MD, principal investigator of the study and chairman of the Department of Ophthalmology at University Hospitals of Cleveland and Case Western Reserve University School of Medicine.

What makes a man behave like a man and a woman a woman? The answer may be partly in your genes. Researchers at the University of Virginia Health System have discovered a new twist on the role that estrogens play in the development of behavioral differences between males and females.
In laboratory tests on mice, the researchers found evidence that an estrogen receptor in the hypothalamus called ERb regulates defeminization, a process by which males lose the ability to display femal
Student-made device sends obstacle warnings to mechanical bug’s brain
Can a robot learn to navigate like a cockroach? To help researchers find out if a mechanical device can mimic the pesky insect’s behavior, a Johns Hopkins engineering student has built a flexible, sensor-laden antenna. Like a cockroach’s own wriggly appendage, the artificial antenna sends signals to a wheeled robot’s electronic brain, enabling the machine to scurry along walls, turn corners and
A new method for navigation at sea, independent of GPS, is being put forward in a dissertation from Linköping University.
Today merchant marine, military, and recreational boat traffic all rely on the global satellite system GPS to determine their position at sea. But sometimes information from the system is incorrect. Poor visibility or lax attention can then spell disaster.
GPS can be jammed, either unintentionally or intentionally. Signals from the satellites can
Increasing ventilation within aircraft cabins can reduce the spread of infectious diseases in-flight, suggests a review published in this week’s issue of The Lancet.
Mark Gendreau (Lahey Clinic Medical Centre, MA, USA) and colleagues reviewed data from studies looking at the transmission of diseases during commercial air travel. They found that while commercial airlines are a suitable environment for the spread of pathogens carried by passengers or crew, the environmental cont
Stereotypes about older workers prevent companies from benefiting from their knowledge and experience, says LSU researcher
Workers are getting older and within five years 20 percent of the workforce will be more than 55, says the U. S. Bureau of Labor Statistics. Those figures are likely to collide with deeply held stereotypes about older workers resisting change and not being able to learn new technologies and systems. Dr. Tracey Rizzuto, assistant professor of psychology at Loui
A team of first-year engineering students at Elizabethtown College have created a proximity sensor system that will help a disabled woman better maneuver her power wheelchair.
The Audible Warning Sonic Sensor System, which is mounted to and powered by Melissa Sneath’s wheelchair, produces a warning sound when she is approaching an object or wall. The sound changes as she gets closer to the object, allowing her to correct her course and avoid a collision.

Ecologists know that when it comes to habitats, size matters, and now a new study finds that contrary to earlier beliefs, that maxim holds true right down to the tiny plants at the bottom of many oceanic and freshwater food chains.
The study, conducted by University of Florida, University of Kansas and University of Texas researchers, is important because it shows that tiny microbes follow the same diversity patterns as larger organisms, said Robert D. Holt, a UF professor of zoolog
A new study by Tulane University researchers, published in the March edition of Molecular Endocrinology, provides insight into one of the ways diethylstilbesterol (DES) may alter the development of the uterus.
DES, a synthetic estrogen, was prescribed to prevent miscarriage in many women who were pregnant between 1941 until 1971. In 1971, DES was banned in the United States due to concerns about the occurrence of cancer and infertility in the daughters of women who took it.
Businesses are struggling to protect their most important asset – their intellectual property (IP) or “know-how”, say researchers at the University of Sussex.
Given that up to 80% of the value of many firms is now formed by their IP, which includes patents, copyright, trademarks and designs, this dramatic finding by the University’s Science and Technology Policy Research Unit (SPRU) raises serious risk management challenges for firms, investors and clients.
The study, jo
Scientists at Uppsala University and the Swedish University for Agricultural Sciences have been participating in an international collaborative project to map the wild origins of the domesticated pig. The findings show that the wild boar was domesticated several times in different parts of Europe and Asia. The study is being presented in today’s issue of the scientific journal Science.
The domestication of animals and plants some 10,000 years ago led to the most significant soc
Part of the immune system’s pro-inflammatory response to bacterial invasion is to increase nitric oxide levels with an enzyme called inducible nitric oxide synthase. In a study published in the Journal of Biological Chemistry, scientists report that the predominantly anti-inflammatory enzyme, endothelial nitric oxide synthase, is also involved in nitric oxide production in response to infection. This discovery may eventually provide a new target to treat sepsis, which is caused by overpr
Chemical pathways allow plant cells to develop in interlocking patterns, adding strength to leaves
Researchers at the University of California, Riverside have unlocked the molecular give and take that allows cells in thin structures such as leaves to develop in a jigsaw-like pattern, providing the leaf a surprising degree of strength. The findings were published in today’s edition of the journal Cell.

In a discovery that could point to new treatments for a wide range of neurodegenerative diseases, Jackson Laboratory researchers have found that high-dose radiation and bone marrow transfer treatments on glaucoma-susceptible mice completely blocked the development of glaucoma, by preventing neurodegeneration.
Glaucomas are among the most common neurodegenerative diseases, and a leading cause of blindness in the United States. Many patients with glaucoma have high intraocular pressu
The largest, most comprehensive study ever done comparing the effectiveness of hand hygiene products shows that nothing works better in getting rid of disease-causing viruses than simply washing one’s hands with good old-fashioned soap and water.
Among the viruses soapy hand washing flushes down the drain is the one that causes the common cold. Other removable viruses cause hepatitis A, acute gastroenteritis and a host of other illnesses.
A separate key finding was
