Device to soak turns water into super-heated steam

Sun-soaking device

Summary:Engineers have built a device that soaks up enough heat from the sun to boil water and produce ‘superheated’ steam hotter than 100 degrees Celsius, without any expensive optics.

MIT engineers have built a device that soaks up enough heat from the sun to boil water and produce “superheated” steam hotter than 100 degrees Celsius,… Read More

Parents and kids spend more time discussing mobile technology than talking about content

Parents, kids spend more time discussing how to use mobile technology

Summary:Most parents would agree that one of the of the biggest modern parenting challenges is monitoring a child’s online activity.

A new study appearing in the Journal of Child and Family Studiesfound that parents spend more time talking with kids about the mechanics of using their mobile devices than they do about what their kids watch and download… Read More

Correlation between obesity & income has developed only in the past 30 years

A correlation between obesity and income

Summary:It is well known that poorer Americans are more likely to be obese or suffer from diabetes; there is a strong negative correlation between household income and both obesity and diabetes. This negative correlation, however, has only developed in the past 30 years, according to researchers. Since 1990, the rise of obesity and diabetes was fastest among… Read More

Excess body weight responsible for almost 4% of cancers worldwide

Excess body weight responsible for nearly 4 percent of cancers

Summary:Excess body weight accounted for approximately 3.9 percent of all cancers worldwide in 2012, a figure that is expected to rise in the coming decades given current trends.

Policies, economic systems, and marketing practices that promote the consumption of energy-dense, nutrient-poor food, changing behavioral patterns that couple high total … Read More

Study finds that large restaurant portions are a global problem

Large restaurant portions a global problem

Summary:A multi-country study finds that large portion sizes in fast food and full service restaurants is not a problem unique to the US. The researchers found that 94 percent of full service meals and 72 percent of fast food meals studied in five countries contained 600 calories or more.

A new multi-country study finds that large, high-calorie portion sizes… Read More

Why is the world’s water supply shrinking

The long dry Why the world's water supply is shrinking

Summary:A global study has found a paradox: our water supplies are shrinking at the same time as climate change is generating more intense rain. And the culprit is the drying of soils, say researchers, pointing to a world where drought-like conditions will become the new normal, especially in regions that are already dry.

A global study has found a paradox: … Read More

Sewing high-tech heating patches to your clothes may be an energy-efficient way to stay warm

An energy-efficient way to stay warm

Summary:What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes — while significantly reducing your electric bill and carbon footprint? Engineers have found a cost-effective way to make thin, durable heating patches by using intense pulses of light to fuse tiny silver wires with polyester.… Read More

Summary:NOAA’s annual report card on the Arctic, released today, shows that the Arctic region experienced the second-warmest air temperatures ever recorded; the second-lowest overall sea-ice coverage; lowest recorded winter ice in the Bering Sea; and earlier plankton blooms due to early melting of sea ice in the Bering Sea.

NOAA’s annual… Read More

Major step closer to a viable recording material for future HD drives

A major step closer to a viable recording material for future hard disk drives

Summary:By tweaking an iron-platinum alloy, researchers are trying to clear a few hurdles slowing the material’s viability as a future perpendicular recording media.

Magnetic recording is the primary technology underpinning today’s large-scale data storage. Now, companies are racing to develop new hard disk devices (HDDs) capable of … Read More
