By meticulously examining sediments in China's Yellow River, a Swedish-Chinese research group are showing that the history of tectonic and climate evolution on Earth may need to be rewritten. Their findings are published today in the highly reputed journal Nature Communications.

To reconstruct how the global climate and topography of the Earth's surface have developed over millions of years, deposits of eroded land sediment transported by rivers to ocean depths are often used. This process is assumed to have been rapid and, by the same token, not to have resulted in any major storages of this sediment as large deposits along the way.

A new paper gives psycholgists a unique glimpse at how humans develop an ability to use tools in childhood while nonhuman primates--such as capuchin monkeys and chimpanzees--remain only occasional tool users.

Dorothy Fragaszy, a psychology professor at the University of Georgia, created two studies to look at how non-human primates and human children differ in completing simple spatial reasoning tasks. 

Much like a game of Operation, human children ages 2, 3 and 4 and adult nonhuman primates were asked to fit a stick, a cross and a tomahawk into a matching cutout space on a tray. Children were also given an opportunity to complete this task by placing the sticks on a mat with a drawing of the matching shape, as well as into a space on a tray.

Since publishing our study on “A scientific basis for regulation deep-sea fishing by depth“ we’ve been subjected to criticism online and in print from fisheries organizations and most recently on this website in an article by Magnus Johnson.

Renewable energy is not very sustainable in the European Union (EU) yet but the food industry, which is heavily reliable on subsidies to stay competitive with the rest of the world, needs renewable energy costs to come down to remain viable.

Until then, the food sector is going to resist using renewable energy, which is a scant 7 percent of their usage, compared to 15 percent in the EU overall. Instead of advocating basic research to improve renewable energy, the call is out to lower meat consumption in a new report. And of course to reduce food choices by shopping locally and seasonally.

. Clothing brand Patagonia gives 1% of its sales “to support environmental organisations around the world”. Carpet-maker Interface takes an “aggressive approach” to reach its goal to source 100% of its “energy needs from renewable sources by 2020”. Nudie Jeans meanwhile, repairs, reuses and recycles its denim products, as well as using organic cotton to produce them in the first place.

By Joel Shurkin, Inside Science -- The notion that Earth’s climate is changing—and that the threat to the world is serious—goes back to the 1980s, when a consensus began to form among climate scientists as temperatures began to rise noticeably. Thirty years later, that consensus is solid, yet climate change and the disruption it may cause remain divisive political issues, and millions of people remain unconvinced.

A new book argues that social scientists should play a greater role in helping natural scientists convince people of the reality of climate change and drive policy.

In the early days of food labeling and regulations, it was just about mandating honesty. If you go to buy mayonnaise, you shouldn't have to wonder if it is mayonnaise (1), and then labels became a marketing distinction.

Better ingredients meant a better product and that appealed to people who cared about higher quality or superior health for their families. 

More recently, labels have become a way to promote self-identification with a world view - you could show you are more ethical and care more about your children and the developing world, and even the whole planet, if you buy a special label.

Osteoporosis, a disease of progressive bone loss, affects 70 percent of the U.S. population older than age 50 - about 50 percent of women and 20 percent of men. These individuals are at risk for fragility fractures, a break that results from a fall, or occurs in the absence of obvious trauma, and most commonly seen in the wrist, the upper arm, the hip, and the spine.  

People who sustain a fragility fracture are at a higher risk for future fractures and face increasing treatment costs. According to a new study, anti-osteoporotic therapy, a treatment intended to increase bone mineral density and slow or stop the loss of bone tissue, can decrease the risk of subsequent fractures by 40 percent.  

A course on critical thinking has generated a new proposal to remove sources of bias in research and improve confidence in published studies.

Social science research got a black eye recently when the authors of several studies were shown to have manipulated data. But the more prevalent issue in the social sciences today is not actual fraud, but subtle and usually inadvertent bias that skews the conclusions of studies and often makes them unrepeatable.

Pioneering new research sheds light on the impact of climate change on subglacial lakes found under the Greenland ice sheet.

A team of experts, led by Dr Steven Palmer from the University of Exeter, has studied the water flow paths from one such subglacial lake, which drained beneath the ice sheet in 2011.

The study shows, for the first time, how water drained from the lake - via a subglacial tunnel. Significantly, the authors present satellite observations that show that a similar event happened in 1995, suggesting that this lake fills and drains periodically.

The study, called Subglacial lake drainage detected beneath the Greenland Ice Sheet is published in the journal Nature Communications.
