The 5 Strangest Facts About Pluto (SPACE.com)

SPACE.com - Pluto is so far away from Earth that everything we know about it can be written down on a couple of 3 x 5 inch index cards. But Pluto will come into clearer focus in a few years' time, though, as NASA's New Horizons probe is due to make a close flyby of the dwarf planet in July 2015, marking the first time a spacecraft has ever visited the frigid, faraway world.

Certain biologic therapies for psoriasis do not appear to increase risk for cardiovascular problems

Although some preliminary reports have indicated an increased risk of major adverse cardiovascular events with the use of certain biologic therapies to treat chronic plaque psoriasis, an analysis of previous studies finds no significant difference in the rate of these events among patients who received these medications compared to patients who received placebo, according to an article in the...

Consuming cholesterol-lowering foods results in greater decrease in LDL than low-saturated-fat diet

Persons with high cholesterol who received counseling regarding a diet that combined cholesterol-lowering foods such as soy protein, nuts and plant sterols over 6 months experienced a greater reduction in their low-density lipoprotein cholesterol (LDL-C) levels than individuals who received advice on a low-saturated fat diet, according to a study in the August 24/31 issue of JAMA.

Diastolic dysfunction appears to worsen over time; associated with increased risk of heart failure

A follow-up of participants in a heart function study finds that the prevalence of left ventricular diastolic dysfunction (left ventricular filling [with blood] is abnormal and is accompanied by elevated filling pressures) had increased; that diastolic function had worsened in a nearly a quarter of patients; and that participants who had diastolic dysfunction were more likely to develop heart...

Landsat image maps aid fire recovery efforts

NASA satellite images regularly map active fires around the world. Once a fire is out, satellite data and maps are also used by scientists to measure and protect the scorched land, and have played an important role in streamlining fire recovery efforts.

Melanin's 'trick' for maintaining radioprotection studied

Sunbathers have long known that melanin in their skin cells provides protection from the damage caused by visible and ultraviolet light. More recent studies have shown that melanin, which is produced by multitudes of the planet's life forms, also gives some species protection from ionizing radiation. In certain microbes, in particular some organisms from near the former nuclear reactor facilities...

Men, women get equal care with Get With The Guidelines

Women received nearly the same quality of care as men at hospitals using the American Heart Association's Get With The Guidelines®–Heart Failure program, according to a study reported in Circulation: Heart Failure, an American Heart Association journal.

New heart scan may speed up diagnosis with less radiation

New technology appears to provide faster, more accurate heart scans for both viewing blood vessels in the heart and measuring blood supply to the heart muscle, while exposing patients to less radiation, researchers report in Circulation: Cardiovascular Imaging, a journal of the American Heart Association.

New theory may shed light on dynamics of large-polymer liquids

A new physics-based theory could give researchers a deeper understanding of the unusual, slow dynamics of liquids composed of large polymers. This advance provides a better picture of how polymer molecules respond under fast-flow, high-stress processing conditions for plastics and other polymeric materials.

Novel cytokine protects mice from colitis

Inflammatory bowel disease (IBD), which affects more than 1 million patients in North America, results from an uncontrolled immune response triggered by environmental factors, such as bacteria, in people genetically predisposed to the disorder. Ulcerative colitis, or inflammation of the lining of the colon, is one such condition.

Study links inactivity with risk factors for Type 2 diabetes

79 million American adults have prediabetes and will likely develop diabetes later in life, according to the Centers for Disease Control and Prevention. As the number of people diagnosed with diabetes continues to grow, researchers are focusing on discovering why the prevalence of the disease is increasing. John Thyfault, an assistant professor in MU's departments of Nutrition and Exercise...

Why East Coast earthquakes travel so far

A rare 5.8 earthquake that rattled the eastern United States on Tuesday was felt over a wide area from Toronto, Canada down to Georgia due to the hard, brittle quality of the ground, experts said.
