Babies learn words differently as they age, researcher finds

COLUMBIA, Mo. – Research has shown that most 18-month-olds learn an average of two to five new words a day; however, little is known about how children process information to learn new words as they move through the preschool years. In a new study, a University of Missouri researcher has found that toddlers learn words differently as they age, and a limit exists as to how many words they can learn each day. These findings could help parents enhance their children's vocabularies and assist speech-language professionals in developing and refining interventions to help children ...

Big surprises can come in small packages

Astronomers using the NASA/ESA Hubble Space Telescope have found a monster lurking in a very unlikely place. New observations of the ultracompact dwarf galaxy M60-UCD1 have revealed a supermassive black hole at its heart, making this tiny galaxy the smallest ever found to host a supermassive black hole. This suggests that there may be many more supermassive black holes that we have missed, and tells us more about the formation of these incredibly dense galaxies. The results will be published in the journal Nature on 18 September 2014. Lying about 50 million light-years ...

Entrepreneurs aren't overconfident gamblers

Leaving one's job to become an entrepreneur is inarguably risky. But it may not be the fear of risk that makes entrepreneurs more determined to succeed. A new study finds entrepreneurs are also concerned about what they might lose in the transition from steady employment to startup. In Entrepreneurship and Loss-Aversion in a Winner-Take-All Society, Professor John Morgan at UC Berkeley's Haas School of Business and co-author Dana Sisak, assistant professor at the Erasmus University Rotterdam, focused on the powerful impact of loss aversion. Loss aversion, or the fear ...

Engineers develop algorithms to switch out and recharge battery modules in electric cars

Imagine being able to switch out the batteries in electric cars just like you switch out batteries in a photo camera or flashlight. A team of engineers at the University of California, San Diego, are trying to accomplish just that, in partnership with a local San Diego engineering company. They have developed smaller units within the battery, called modules, and a battery management system that will allow them to swap out and recharge the modules, rather than swapping out the whole battery, which is cumbersome and requires large, heavy equipment. They recently presented ...

Protein variant may boost cardiovascular risk by hindering blood vessel repair

DALLAS – September 17, 2014 – Researchers at UT Southwestern Medical Center have found that the most common variant of the circulating protein apolipoprotein E, called apoE3, helps repair the lining of blood vessels. Individuals with another variant, called apoE4, do not get the benefit of this repair, putting them at higher risk for cardiovascular disease. "We believe that we have identified one mechanism by which apoE3 promotes a healthy cardiovascular system and why a genetic variant, apoE4, is detrimental," said Dr. Philip Shaul, Professor of Pediatrics and Vice Chair ...

Coral growth rate plummets in 30-year comparison

Washington, DC— A team of researchers working on a Carnegie expedition in Australia's Great Barrier Reef has documented that coral growth rates have plummeted 40% since the mid-1970s. The scientists suggest that ocean acidification may be playing an important role in this perilous slowdown. In a quest for historical context on the peril facing coral reefs, the team compared current measurements of the growth rate of a section of Australia's Great Barrier Reef with similar measurements taken more than 30 years ago. Their work is published in Geochimica et Cosmochimica ...

EARTH Magazine: The Bay Area's next 'big one' could strike as a series of quakes

Alexandria, Va. — Most people are familiar with the Great 1906 San Francisco Earthquake and are aware of the earthquake risk posed to the Bay Area — and much of California — by the San Andreas Fault. Most people are not aware, however, that a cluster of large earthquakes struck the San Andreas and quite a few nearby faults in the 17th and 18th centuries. That cluster, according to new research, released about the same amount of energy throughout the Bay Area as the 1906 quake. Thus, it appears that the accumulated stress on the region's faults could be released in a series ...
