  • Dragon cargo craft launch scrubbed; Station crew preps for spacewalk
    Monday's launch attempt of the SpaceX Dragon cargo craft, loaded with nearly 5,000 pounds of supplies for the International Space Station's Expedition 39 crew, was scrubbed due to a helium leak on the Falcon 9 first stage. The next launch opportunity would be Friday, April 18 at 3:25 p.m. EDT if the issue can be resolved.

  • NASA Cassini images may reveal birth of a Saturn moon
    NASA's Cassini spacecraft has documented the formation of a small icy object within the rings of Saturn that may be a new moon, and may also provide clues to the formation of the planet's known moons.

  • We're over the hill at 24, study says
    It's a hard pill to swallow, but if you're over 24 years of age you've already reached your peak in terms of your cognitive motor performance, according to a new study. In one of the first social science experiments to rest on big data, the researchers investigate when we start to experience an age-related decline in our cognitive motor skills and how we compensate for that.

  • Everest trek shows how some people get type II diabetes
    Scientists have gained new insights into the molecular process of how some people get type II diabetes, which could lead to new ways of preventing people from getting the condition. The research, which took place on Mount Everest, assessed the mechanisms by which low oxygen levels in the body -- known as hypoxia -- are associated with the development of insulin resistance. Insulin resistance is when cells fail to respond to insulin in the body. Insulin enables the body to regulate sugar levels. Too much sugar can be toxic and leads to type II diabetes.

  • Severe sleep apnea linked to increased risk of stroke, cancer, death
    Moderate to severe obstructive sleep apnea is independently associated with an increased risk of stroke, cancer and death. Results of the 20-year follow-up study show that people with moderate to severe obstructive sleep apnea were four times more likely to die (hazard ratio = 4.2), nearly four times more likely to have a stroke (HR = 3.7), three times more likely to die from cancer (HR = 3.4), and 2.5 times more likely to develop cancer. Results were adjusted for potential confounding factors such as body mass index, smoking status, total cholesterol and blood pressure.
