Watch Your Language! of Course–But How Do We Actually Do That?

Nothing seems more automatic than speech. We produce an estimated 150 words a minute, and make a mistake only about once every 1,000 words. We stay on track, saying what we intend to, even when other words distract us—from the radio, say, or a road sign we pass while driving.

An upcoming study in Psychological Science, a journal of the Association for Psychological Science, shows for the first time why we so rarely speak those irrelevant words: We have a “verbal self-monitor” between the mental production of speech and the actual uttering of words that catches any irrelevant items coming from outside of the speaker.

Beautiful People Are Happier, Economists Find

AUSTIN, Texas — Good-looking people are generally happier than their plain looking or unattractive counterparts, largely because of the higher salaries, other economic benefits and more successful spouses that come with beauty, according to new research from economists at The University of Texas at Austin.

This holds true for both men and women and across different cultures, authors Daniel Hamermesh and Jason Abrevaya report in their paper “‘Beauty is the Promise of Happiness’?,” [PDF] which they are releasing to economists this week. The paper is posted at https://ftp.iza.org/dp5600.pdf [PDF], the Web site for the German-based Institute for the Study of Labor (IZA). (more…)

Research Shows Not Only the Fittest Survive

Darwin’s notion that only the fittest survive has been called into question by new research published in Nature.

A collaboration between the Universities of Exeter and Bath in the UK, with a group from San Diego State University in the US, challenges our current understanding of evolution by showing that biodiversity may evolve where previously thought impossible.

The work represents a new approach to studying evolution that may eventually lead to a better understanding of the diversity of bacteria that cause human diseases. (more…)

PASADENA, Calif. – The Kilauea volcano that recently erupted on the Big Island of Hawaii will be the target for a NASA study to help scientists better understand processes occurring under Earth’s surface.

A NASA Gulfstream-III aircraft equipped with a synthetic aperture radar developed by NASA’s Jet Propulsion Laboratory in Pasadena, Calif., is scheduled to depart Sunday, April 3, from the Dryden Aircraft Operations Facility in Palmdale, Calif., to the Big Island for a nine-day mission. (more…)

Novel Nanowires Boost Fuel Cell Efficiency

Fuel cells have been touted as a cleaner solution to tomorrow’s energy needs, with potential applications in everything from cars to computers.

But one reason fuel cells aren’t already more widespread is their lack of endurance. Over time, the catalysts used even in today’s state-of-the-art fuels cells break down, inhibiting the chemical reaction that converts fuel into electricity. In addition, current technology relies on small particles coated with the catalyst; however, the particles’ limited surface area means only a fraction of the catalyst is available at any given time.

2,000 Year-old Deep-sea Black Corals call Gulf of Mexico Home

SANTA CRUZ, Calif. — For the first time, scientists have been able to validate the age of deep-sea black corals in the Gulf of Mexico. They found the Gulf is home to 2,000 year-old deep-sea black corals, many of which are only a few feet tall.

These slow-growing, long-living animals thrive in very deep waters—300 meters (984 feet) and deeper—yet scientists say they are sensitive to what is happening in the surface ocean as well as on the sea floor. (more…)
