A wife's happiness is more crucial than her husband's in keeping marriage on track Posted: 12 Sep 2014 10:48 AM PDT When it comes to a happy marriage, a new study finds that the more content the wife is with the long-term union, the happier the husband is with his life no matter how he feels about the nuptials.

Cutting the cord on soft robots: Machine walks through snow, flames and can be run over by cars Posted: 11 Sep 2014 03:07 PM PDT Engineers have developed the world's first untethered soft robot -- and demonstrated that the quadruped, which can literally stand up and walk away from its designers, can walk through snow, fire and even be run over by a car. The hope is that such robots might one day serve as a search and rescue tool following disasters.

15 years of carbon dioxide emissions on Earth mapped Posted: 11 Sep 2014 12:18 PM PDT Scientists have developed a new approach to estimate carbon dioxide emissions from burning fossil fuels -- one that provides crucial information to policymakers. Called the 'Fossil Fuel Data Assimilation System,' this system was used to quantify 15 years of carbon dioxide emissions, every hour, for the entire planet -- down to the city scale. Until now, scientists have estimated greenhouse gas emissions at coarser scales or used less reliable techniques.

Simple method turns human skin cells into immune strengthening white blood cells Posted: 11 Sep 2014 11:27 AM PDT For the first time, scientists have turned human skin cells into transplantable white blood cells, soldiers of the immune system that fight infections and invaders. The work could let researchers create therapies that introduce into the body new white blood cells capable of attacking diseased or cancerous cells or augmenting immune responses against other disorders.

Ceramics don't have to be brittle: Incredibly light, strong materials recover original shape after being smashed Posted: 11 Sep 2014 10:54 AM PDT Materials scientists have developed a method for creating new structural materials by taking advantage of the unusual properties that solids can have at the nanometer scale. They have used the method to produce a ceramic (e.g., a piece of chalk or a brick) that contains about 99.9 percent air yet is incredibly strong and can recover its original shape after being smashed by more than 50 percent.

'Hot Jupiters' provoke their own host suns to wobble Posted: 11 Sep 2014 10:54 AM PDT Blame the 'hot Jupiters.' These large, gaseous exoplanets can make their suns wobble when they wend their way through their own solar systems to snuggle up against their suns, according to new research.

Scientists revert human stem cells to pristine state Posted: 11 Sep 2014 09:50 AM PDT Researchers have resolved a long-standing challenge in stem cell biology by successfully 'resetting' human pluripotent stem cells to a fully pristine state, at a point of their greatest developmental potential.

Breast milk reveals a correlation between dietary fats and academic success Posted: 11 Sep 2014 06:47 AM PDT You are what you eat, the saying goes, and now a study suggests that the oft-repeated adage applies not just to physical health, but to brain power as well. Researchers compared the fatty acid profiles of breast milk from women in over two dozen countries with how well children from those same countries performed on academic tests. Their findings show that the amount of omega-3 docosahexaenoic acid (DHA) in a mother's milk is the strongest predictor of test performance. It outweighs national income and the number of dollars spent per pupil in schools.

Last decade's slowdown in global warming enhanced by an unusual climate anomaly Posted: 11 Sep 2014 06:29 AM PDT A hiatus in global warming ongoing since 2001 is due to a combination of a natural cooling phase, known as multidecadal variability (MDV) and a downturn of the secular warming trend. The exact causes of the latter, unique in the entire observational record going back to 1850, are still to be identified, according to a new article.

Ancient swamp creature had lips like Mick Jagger Posted: 10 Sep 2014 09:04 AM PDT A swamp-dwelling, plant-munching creature that lived 19 million years ago in Africa has been named after Rolling Stones lead singer Sir Mick Jagger, because of its big, sensitive lips and snout. The name of the animal, Jaggermeryx naida, translates to 'Jagger's water nymph.'
