When a marathon runner approaches the finish line of race but suddenly collapses, it's reasonable to assume it is because of a muscle issue. It might also be a braking mechanism in the brain which swings into effect and makes us people tired to continue. What may be occurring is what is referred to as 'central fatigue'.


A survey analysis finds both that the public is supportive of government action to curb obesity, diabetes, and other noncommunicable diseases - but don't like interventions that appear intrusive or coercive.

The Harvard School of Public Health (HSPH) analysis also found that support was higher for interventions that help people make more healthful choices, such as menu labeling requirements, than for interventions that penalize certain choices or health conditions, such as charging higher insurance premiums for obese individuals.


If your children stump you with 'cite your data' claims on why they need to eat leafy green vegetables, even though we got to the top of the food chain so we wouldn't have to do that, here is good news; a new study found that that an immune cell population essential for intestinal health could be controlled by leafy greens in your diet.


Though staunchly opposed to nuclear power in some respects, like the controversial decision to scuttle the Yucca Mountain project, the Obama administration said in 2012 that it was "jumpstarting" the nuclear industry.


While America moves toward an egalitarian approach to medical care, another study has found that the quality of cares matters in things like advanced head and neck cancers.

The paper in Cancer says that patients who were treated at hospitals that saw a high number of head and neck cancers were 15 percent less likely to die of their disease as compared to patients who were treated at hospitals that saw a relatively low number. The study also found that such patients were 12 percent less likely to die of their disease when treated at a National Cancer Institute -designated cancer center.
 


There is evidence of an ancient micro-continent buried beneath the Indian Ocean. The ancient continent is a thousand miles in length and extends from the Seychelles to the island of Mauritius. It contains rocks up to 2 billion years old - much older than the Indian Ocean itself, which has formed only in the last 165 million years. 

The research team believe that this micro-continent, which they have named Mauritia, was split off from Madagascar and India between 61 and 83 million years ago as one single land mass rifted apart to form the continents around the Indian Ocean that we know today.

Much of it was then smothered by thick lava deposits as a result of volcanic activity and submerged beneath the waves.
