WASP gives NASA's planetary scientists new observation platform Posted: 08 Feb 2014 05:07 AM PST Scientists who study Earth, the sun and stars have long used high-altitude scientific balloons to carry their telescopes far into the stratosphere for a better view of their targets. Not so much for planetary scientists. That's because they needed a highly stable, off-the-shelf-type system that could accurately point their instruments and then track planetary targets as they moved in the solar system. That device now exists.

Thinking skills take biggest hit from anxiety in midlife women with HIV Posted: 08 Feb 2014 05:07 AM PST Hot flashes, depression, and most of all, anxiety, affect the thinking skills of midlife women with HIV, so screening for and treating their anxiety may be especially important in helping them function, according to a study just published. The reproductive stage, whether it was premenopause, perimenopause or postmenopause, did not seem to be related to these women's thinking skills.

Huntington disease prevention trial shows creatine safe, slows progression Posted: 08 Feb 2014 05:07 AM PST The first clinical trial of a drug intended to delay the onset of symptoms of Huntington disease reveals that high-dose treatment with the nutritional supplement creatine was safe and well tolerated by most participants. In addition, neuroimaging showed a treatment-associated slowing of regional brain atrophy, evidence that creatine might slow the progression of presymptomatic disease.

Women fare worse than men following stroke Posted: 08 Feb 2014 05:05 AM PST The good news: More people survive stroke now than 10 years ago due to improved treatment and prevention. The bad news: Women who survive stroke have a worse quality of life than men, according to a study published.

Stroke trigger more deadly for African-Americans Posted: 08 Feb 2014 05:05 AM PST In a new study, results show that African-Americans were 39 times more likely to die of a stroke if they were exposed to an infection.

Bio scaffolds categorized by characteristic cell shapes Posted: 07 Feb 2014 10:30 AM PST Getting in the right shape might be just as important in a biology lab as a gym. Shape is thought to play an important role in the effectiveness of cells grown to repair or replaced damaged tissue in the body. To help design new structures that enable cells to "shape up," researchers have come up with a way to measure, and more importantly, classify, the shapes cells tend to take in different environments.

Surprising new clue to the roots of hunger, neurons that drive appetite Posted: 07 Feb 2014 10:29 AM PST A scientific team has made a surprising discovery about the brain's hunger-inducing neurons, a finding with important implications for the treatment of obesity.

Exercise may slow progression of retinal degeneration Posted: 07 Feb 2014 08:40 AM PST Moderate aerobic exercise helps to preserve the structure and function of nerve cells in the retina after damage, according to an animal study. The findings suggest exercise may be able to slow the progression of retinal degenerative diseases.

GMO soybean pollen threatens Mexican honey sales Posted: 07 Feb 2014 05:39 AM PST Researchers have helped rural farmers in Mexico to quantify the genetically modified organism soybean pollen in honey samples rejected for sale in Germany.

Zoo offers blueprint for conserving native wildlife Posted: 07 Feb 2014 05:37 AM PST Researchers have developed a blueprint to help zoos plan strategies for the conservation of native wildlife in and around their gardens.

Potential novel treatment against septic shock, one of the leading causes of mortality in ICUs Posted: 07 Feb 2014 05:37 AM PST Septic shock is caused by excessive and systemic reaction of the entire body against infectious agents, in most cases of bacterial origin. The number of deaths by septic shock in intensive care units is very high and is still increasing, despite numerous large scale clinical trials. Scientists demonstrated in a mouse study that a potential novel treatment for sepsis may consist of the simultaneous neutralization of two harmful cytokines in the blood circulation, namely interleukin-1 and interleukin-18.

Acute Kidney Injury May Be a Risk Factor for Later Heart Problems Posted: 07 Feb 2014 05:36 AM PST Hospitalized patients who recovered from acute kidney injury had a 67% increased risk of experiencing coronary events or dying during a recent study, suggesting that there is a linkage between the two. Acute kidney injury's harmful effects on heart health were comparable to those attributed to diabetes.

Histones may hold the key to the generation of totipotent stem cells Posted: 06 Feb 2014 10:36 AM PST One major challenge in stem cell research has been to reprogram differentiated cells to a totipotent state. Researchers have identified a duo of histone proteins that dramatically enhance the generation of induced pluripotent stem cells (iPS cells) and may be the key to generating induced totipotent stem cells.
