We all have different criteria for what we consider risky. However, numerous studies have suggested that we tend to perceive familiar products and activities as being less risky and hazardous than unfamiliar ones. If something is familiar, the thinking goes, it is comfortable and safe. But how do we know if something is familiar? We often rely on a simple shortcut: If it is easy to perceive, remember or pronounce, we have probably seen it before. If so, will a product's name and how easy it is to pronounce, affect how we view the product?

For all of the conveniences of online shopping -- no crowds, easy parking, seemingly endless choices -- it can't always compete with the real thing. At least not yet.

GAINESVILLE, Fla. — The recession may be responsible for a slump of a different sort: an unexpected dive in shark attacks, says a University of Florida researcher.
Shark attacks worldwide in 2008 dipped to their lowest level in five years, a sign that Americans may be forgoing vacation trips to the beach, said George Burgess, ichthyologist and director of the International Shark Attack File, which is housed at UF.
Mating can be exhausting. When fruit flies mate, the females' genes are activated to roughly the same extent as when an immune reaction starts. This is shown in a study at Uppsala University that is now appearing in the scientific publication, Journal of Evolutionary Biology.*
Using a combination of behavioral studies and genomic technology, so-called microarrays, researchers at Uppsala University can show how fruit fly females are affected by mating.
SALT LAKE CITY, Feb. 19, 2009 — The scientific field that focuses on the ultra-small — nanotechnology — will play the biggest single role in the 237th National Meeting & Exhibition of the American Chemical Society (ACS), which takes place here from March 22-26.

Self-control is one of our most cherished values. We applaud those with the discipline to regulate their appetites and actions, and we try hard to instill this virtue in our children. We celebrate the power of the mind to make hard choices and keep us on course. But is it possible that willpower can sometimes be an obstacle rather than a means to happiness and harmony?
DURHAM, N.C. -- What do Saturn and flowers have in common?
As shapes, both possess certain symmetries that are easily recognizable in the natural world. Now, at an extremely small level, researchers from Duke University and the University of Massachusetts have created a unique set of conditions in which tiny particles within a solution will consistently assemble themselves into these and other complex shapes.
What do poor forest farmers want from China's ongoing forest land reform?Well, it is not private ownership of the land that makes them invest. What Chinese farmers value most and what attracts them to investments that can raise their standard of living and contribute to sustainable forestry is secure rights of usage, as shown by Ping Qin's doctoral thesis in economics at the School of Business, Economics and Law, University of Gothenburg, Sweden.
Athens, Ga. – During a research trip to Puerto Rico, ecologist James Porter took samples from underwater nuclear bomb target USS Killen, expecting to find evidence of radioactive matter – instead he found a link to cancer. Data revealed that the closer corals and marine life were to unexploded bombs from the World War II vessel and the surrounding target range, the higher the rates of carcinogenic materials.
