NIH study shows 32 million Americans have autoantibodies that target their own tissues Posted: 13 Jan 2012 06:38 AM PST More than 32 million people in the United States have autoantibodies, which are proteins made by the immune system that target the body's tissues and define a condition known as autoimmunity, a study shows. The first nationally representative sample looking at the prevalence of the most common type of autoantibody, known as antinuclear antibodies (ANA), found that the frequency of ANA is highest among women, older individuals, and African-Americans.

Dark chocolate and red wine are heart-healthy foods of love, dietitians say Posted: 13 Jan 2012 06:38 AM PST Dietitian says resveratrol which lowers blood sugar is found in red wine and also dark chocolate, making them ideal for heart holidays like Valentine's Day and year round consumption for heart health.

Particle-free silver ink prints small, high-performance electronics Posted: 13 Jan 2012 06:36 AM PST Materials scientists have developed a new reactive silver ink for printing high-performance electronics on ubiquitous, low-cost materials such as flexible plastic, paper or fabric substrates. The reactive ink has several advantages over particle-based inks: low processing temperature, high conductivity, and the ability to print very small features.

Horse fly named in honor of Beyonce Posted: 13 Jan 2012 06:36 AM PST A previously unnamed species of horse fly whose appearance is dominated by its glamorous golden lower abdomen has been named in honor of American pop diva, Beyonce -- a member of the former group Destiny's Child, that recorded the 2001 hit single, "Bootylicious."

What can be done to slow climate change? Posted: 12 Jan 2012 04:34 PM PST Scientists have detailed 14 key air pollution control measures that, if implemented, could slow the pace of global warming, improve health and boost agricultural production.

New clue in battle against Australian Hendra virus: African bats have antibodies that neutralize deadly virus Posted: 12 Jan 2012 04:34 PM PST A new study on African bats provides a vital clue for unraveling the mysteries in Australia's battle with the deadly Hendra virus.

Cold winters caused by warmer summers, research suggests Posted: 12 Jan 2012 04:34 PM PST Scientists have offered up a convincing explanation for the harsh winters recently experienced in the Northern hemisphere: increasing temperatures and melting ice in the Arctic regions creating more snowfall in the autumn months at lower latitudes.

Newly identified type of immune cell may be important protector against sepsis Posted: 12 Jan 2012 11:22 AM PST Investigators have discovered a previously unknown type of immune cell, a B cell that can produce the important growth factor GM-CSF, which stimulates many other immune cells. They also found that these novel cells may help protect against the overwhelming, life-threatening immune reaction known as sepsis.

Don't know much about charter schools Posted: 12 Jan 2012 11:22 AM PST Researchers say the best studies reflect only the best charter schools and must be boosted with "value-added" approaches for all the rest.

World's smallest magnetic data storage unit Posted: 12 Jan 2012 11:22 AM PST Scientists have built the world's smallest magnetic data storage unit. It uses just twelve atoms per bit, the basic unit of information, and squeezes a whole byte (8-bit) into as few as 96 atoms.

Diverse ecosystems are crucial climate change buffer Posted: 12 Jan 2012 11:22 AM PST Preserving diverse plant life will be crucial to buffer the negative effects of climate change and desertification in in the world's drylands, according to a new landmark study.

Genes and disease mechanisms behind a common form of muscular dystrophy discovered Posted: 12 Jan 2012 10:43 AM PST Continuing a series of groundbreaking discoveries begun in 2010 about the genetic causes of the third most common form of inherited muscular dystrophy, scientists have identified the genes and proteins that damage muscle cells, as well as the mechanisms that can cause the disease.
