From The Great Wall To The Great Collider

Science2.0 - February 8, 2016 - 10:55am
With a long delay, last week I was finally able to have a look at the book "From the Great Wall to the Great Collider - China and the Quest to Uncover the Inner Workings of the Universe", by Steve Nadis and Shing-Tung Yau. And I would like to report about my impressions here.

Increase In Volcanic Eruptions At The End Of The Ice Age Caused By Melting Ice Caps And Erosion

Science2.0 - February 8, 2016 - 6:26am

The combination of erosion and melting ice caps led to a massive increase in volcanic activity at the end of the last ice age, according to new research. As the climate warmed, the ice caps melted, decreasing the pressure on the Earth's mantle, leading to an increase in both magma production and volcanic eruptions. The researchers, led by the University of Cambridge, have found that erosion also played a major role in the process, and may have contributed to an increase in atmospheric carbon dioxide levels.

Can Animals Thrive Without Oxygen?

Science2.0 - February 8, 2016 - 6:26am

In 2010, a research team garnered attention when it published evidence of finding the first animals living in permanently anoxic conditions at the bottom of the sea. But a new study, led by scientists at the Woods Hole Oceanographic Institution (WHOI), raises doubts.

One alternative scenario is that cadavers of multicellular organisms were inhabited by bacteria capable of living in anoxic conditions, and these "bodysnatchers" made it seem that the dead animals were living, said Joan Bernhard, a geobiologist with WHOI and the lead author of the new study published in the December 2015 issue of the scientific journal BMC Biology.

OFF! Clip-On Device May Protect Against Mosquitoes That Transmit Zika

Science2.0 - February 7, 2016 - 9:51pm

A product called the OFF! Clip-On repellent device could be an effective tool for preventing bites from the Aedes aegypti mosquito, the primary vector of Zika, chikungunya, dengue, and yellow fever, though DEET, a permethrin or even good old-fashioned DDT will also do the trick, unless you are a Joe Mercola or SourceWatch reader and think science is a vast, right-wing conspiracy out to give you cancer.

Snake Gait

Science2.0 - February 7, 2016 - 6:12pm

It has no wheels or legs or anything to help itself along, and yet it is able to move and to move quite fast. In terms of mobility, the snake is a masterpiece of engineering, and it is no coincidence that it should be studied to uncover the physics underlying its locomotion. Giancarlo Cicconofri, SISSA research fellow, and Antonio DeSimone, SISSA professor and head of MathLab, the School's laboratory for mathematical modelling and scientific computing, have developed a mathematical model to describe in detail slithering, one of the characteristic ways in which snakes move by propagating lateral undulations along the body, and described in their model as "snake in a tube".

Front Of Package Food Labels Do Not Mean A Food Is Healthy

Science2.0 - February 7, 2016 - 6:11pm

CHICAGO-- American grocery shoppers face an array of front of pack (FOP) nutrition and health claims when making food selections. But relying on the front of pack (FOP) claims to determine the nutrition quality of the food may not be a consumer's best option. In the January issue of the Journal of Food Science study, published by the Institute of Food Technologists (IFT), researchers from The Ohio State University and Saint Joseph's University, Philadelphia examined and analyzed front of pack nutrition claims on more than 2,200 breakfast cereal and prepared meals released for sale between 2006 and 2010. What they found was that no type or number of front of pack claims could distinguish "healthy" foods.
