Cool jobs: Brainy ways to battle obesity. Science News for Students

About one in every six children and teens throughout the United States are very overweight, meaning obese. Some one-third of adults are, too. Those data come from the Centers for Disease Control and Prevention in Atlanta, Ga. Carrying those extra pounds significantly ups the risks for disease. High blood pressure, diabetes, liver disease and breathing problems are just a few of the conditions linked to excess body weight.  Read more…

Replacing butter with vegetable oils does not cut heart disease risk. Science Daily

Butter might not be a health food, but researchers unearthed more evidence that replacing it with vegetable oils does not decrease risk of heart disease

New research of old data suggests that using vegetable oils high in linoleic acid failed to reduce heart disease and overall mortality even though the intervention reduced cholesterol levels. And researchers found that consuming vegetable oils might actually be worse for heart health than eating butter.  Read more…

Ice, Cream… and Chemistry. Chemmatters.

There is perhaps no fonder childhood memory than the local ice cream truck driving through the neighborhood, music blaring from its tinny speakers, beckoning all to partake of its frosty delights. But ice cream is not just for kids. U.S. residents consume 1.5 billion gallons of ice cream each year; that’s roughly 5 gallons (19 liters) per person! The ice cream we all enjoy is the result of years of experimentation involving—you guessed it—chemistry!  Read more…

Black hole smashup sent out ‘yottawatts’ of power. Science Daily

A black hole collision, detected last September, served as the basis for confirming the existence of gravity waves. Scientists were only able to see those waves, or the effects they had on space-time, because they came from an explosion that blasted out such an intensely big amount of power. That energy is measured in watts. And the black-hole smashup released a mind-blowing amount.  Read more…

Cause of global warming: Consensus on consensus. Science Daily

A research team confirms that 97 percent of climate scientists agree that climate change is caused by humans.  Read more…
