Some of the earliest humans to inhabit America came from Europe according to a new book.

Across Atlantic Ice puts forward a compelling case for people from northern Spain travelling to America by boat, following the edge of a sea ice shelf that connected Europe and America during the last Ice Age, 14,000 to 25,000 years ago.

Across Atlantic Ice is the result of more than a decade’s research by leading archaeologists Professor Bruce Bradley of the University of Exeter and Dr Dennis Stanford of the Smithsonian Institution. Through archaeological evidence, they turn the long-held theory of the origins of New World populations on its head.

For more than 400 years, it has been claimed that people first entered America from Asia, via a land bridge that spanned the Bering Sea. We now know that some people did arrive via this route nearly 15,000 years ago, probably by both land and sea. (more…)

African-American women make up a disproportionate number of HIV/AIDS cases in the United States. Researchers from North Carolina State University are trying to change that, leading a National Science Foundation project aimed at developing HIV/AIDS prevention materials that resonate with African-American female college students.

African-Americans represent approximately 14 percent of the U.S. population, but accounted for an estimated 44 percent of new HIV infections in 2009. The estimated rate of new HIV infections among African-American women was 15 times that of white women and over three times that of Latina women. (more…)

*Mechanism holds potential for improving recall in dementia patients*

Have you ever gone to the movies and forgotten where you parked the car? New UCLA research may one day help you improve your memory.

UCLA neuroscientists have demonstrated that they can strengthen memory in human patients by stimulating a critical junction in the brain. Published in the Feb. 9 edition of the New England Journal of Medicine, the finding could lead to a new method for boosting memory in patients with early Alzheimer’s disease. (more…)

EAST LANSING, Mich. — Many people are willing to pay a premium for ethanol, but not enough to justify the government mandate for the corn-based fuel, a Michigan State University economist argues.

Soren Anderson studied the demand for ethanol, or E85, in the United States. He found that when ethanol prices rose 10 cents per gallon, demand for ethanol fell only 12 percent to 16 percent on average. (more…)

New Device Removes Stroke-Causing Blood Clots Better Than Standard Treatment

An experimental device for removing blood clots in stroke patients dramatically outperformed the standard mechanical treatment, according to research presented by UCLA Stroke Center director Dr. Jeffrey L. Saver at the American Stroke Association’s 2012 international conference in New Orleans on Feb. 3.

The SOLITAIRE Flow Restoration Device is among an entirely new generation of devices designed to remove blood clots from blocked brain arteries in patients experiencing stroke. It has a self-expanding, stent-like design and, once inserted into a clot using a thin catheter tube, it compresses and traps the clot. The clot is then removed by withdrawing the device, thus reopening the blocked blood vessel. (more…)
