UCLA life scientists and their colleagues have discovered the first evidence of the H1N1 virus in animals in Africa. In one village in northern Cameroon, a staggering 89 percent of the pigs studied had been exposed to the H1N1 virus, commonly known as the swine flu.
“I was amazed that virtually every pig in this village was exposed,” said Thomas B. Smith, director of UCLA’s Center for Tropical Research and the senior author of the research. “Africa is ground zero for a new pandemic. Many people are in poor health there, and disease can spread very rapidly without authorities knowing about it.” (more…)
*Research could lead to techniques to improve fertilization in humans*
In new research that could have implications for improving fertilization in humans and other mammals, life scientists studied interactions between individual sperm and eggs in red abalone, an ocean-dwelling snail, and made precise chemical measurements and physical models of these interactions. They are the first scientists to do so.
By simulating the natural habitat of the abalone in the laboratory, the scientists were able to determine the conditions under which sperm–egg encounters and fertilization were most likely to occur. (more…)
SANTA CRUZ, Calif. – Knowing that the U.S. west coast was battered during the winter before last by a climatic pattern expected more often in the future, scientists have now pieced together a San Diego-to-Seattle assessment of the damage wrought by that winter’s extreme waves and higher-than-usual water levels. Getting a better understanding of how the 2009-10 conditions tore away and reshaped shorelines will help coastal experts better predict future changes that may be in store for the Pacific coast, the researchers say.
“The stormy conditions of the 2009-10 El Niño winter eroded the beaches to often unprecedented levels at sites throughout California and vulnerable sites in the Pacific Northwest,” said Patrick Barnard, USGS coastal geologist. In California, for example, winter wave energy was 20 percent above average for the years dating back to 1997, resulting in shoreline erosion that exceeded the average by 36 percent, he and his colleagues found.

*Chairman and CEO Samuel J. Palmisano Says Managing for the Long Term Will Drive Growth for Next 100 Years*
ARMONK, N.Y., – 16 Jun 2011: IBM today is marking the 100th anniversary of its founding on June 16, 1911. To celebrate the milestone, the company is releasing a book, “Making the World Work Better: The Ideas That Shaped a Century and a Company,” debuting a new film, “Wild Ducks,” and ringing the Opening Bell at the New York Stock Exchange.
During its first century, IBM has played a leading role in transforming business, science and society. The company’s history can be seen as a succession of key milestones – from investing in a research lab in the depths of the Great Depression, to developing the first hard disk drive that created the data storage industry, to working with the U.S. government to develop the Social Security System. It continued with such “big bets” as a radical new computing model, the System/360 mainframe; the invention of the UPC code; the invention of the IBM Personal Computer that launched the PC revolution; and the recent development of Watson, the computer that triumphed on the TV game show Jeopardy!.

AUSTIN, Texas — Global warming is clearly affecting plants and animals, but we should not try to tease apart the specific contribution of greenhouse gas driven climate change to extinctions or declines of species at local scales, biologists from The University of Texas at Austin advise.
“Yes, global warming is happening. Yes, it is caused by human activities. And yes, we’ve clearly shown that species are impacted by global warming on a global scale,” says Parmesan, associate professor of integrative biology. (more…)
