3 Short Walking Breaks Can Reverse Harm From 3 Hours of Sitting

An anonymous reader writes: Medical researchers have been steadily building evidence that prolonged sitting is awful for your health. One major problem is that blood can pool in the legs of a seated person, causing arteries to start losing their ability to control the rate of blood flow. A new experimental study (abstract) has discovered it's quite easy to negate these detrimental health effects: all you need to do is take a leisurely, 5-minute walk for every hour you sit. "The researchers were able to demonstrate that during a three-hour period, the flow-mediated dilation, or the expansion of the arteries as a result of increased blood flow, of the main artery in the legs was impaired by as much as 50 percent after just one hour. The study participants who walked for five minutes for each hour of sitting saw their arterial function stay the same — it did not drop throughout the three-hour period. Thosar says it is likely that the increase in muscle activity and blood flow accounts for this."

China's Island Factory

Slashdot - Tue, 09/09/2014 - 8:45pm
An anonymous reader writes: The BBC has a lengthy investigative report about China's efforts to create and expand artificial islands in the South China Sea. They've been going to coral reefs and atolls, dredging the bottom for material, and dumping it on top of the reef to create new land. On at least one of the new islands, China will build an air base large enough for fighter jets to use. This highlights one of China's main reasons for constructing these islands: sovereignty and strategic control of the surrounding area. "The U.S. government does not acknowledge China's claim, and the U.S. Pacific fleet continues to sail regularly through the South China Sea. But the Chinese navy is beginning to grow more assertive. In December 2013 China sailed its brand new aircraft carrier, the Liaoning, into the South China Sea for the first time. Shadowing it, at about 30 nautical miles, came the U.S. Navy cruiser USS Cowpens. A Chinese amphibious assault ship approached and ordered it to leave the area. The commander of the Cowpens refused, saying he was sailing in 'international waters.'"

Proactive office ergonomics can increase job satisfaction, employee retention

Science Daily - Tue, 09/09/2014 - 8:23pm
Although office ergonomics training programs have been shown to improve employee well-being and productivity, in many cases training occurs only after complaints are logged. New research demonstrates that a comprehensive and proactive workplace ergonomics program can help to prevent discomfort and injury.

Two-dimensional electron liquids: Looking for novel forms of superconductivity

Science Daily - Tue, 09/09/2014 - 8:23pm
Truly two-dimensional objects are rare. Even a thin piece of paper is trillions of atoms thick. When physicists do succeed in producing 2D systems, quantum interactions can lead to new phenomena and Nobel prizes. Two examples: graphene -- single-atom-thick sheets of carbon atoms -- has unique mechanical, electrical, and optical properties; and two-dimensional electron gases (2DEG) -- planar collections of electrons supported at the interface between certain semiconductors such as gallium arsenide -- allow the observation of such emergent behaviors as the quantum Hall effect and the spin Hall effect. Using an overlying bath of ionic liquid, a piece of superconductor -- divided by an insulating strip -- supports narrow tunnels which permit currents to flow between.

Intel Releases SD-Card-Sized PC, Unveils Next 14nm Chip

Slashdot - Tue, 09/09/2014 - 8:02pm
szczys writes: Intel is upping their bid for a place at the efficient-yet-powerful device table. They've launched their Edison board, which features an x86 based SoC running at 100 MHz. The footprint measures 35.5mm x 25.0mm and offers a 70-pin connector to break out 40 pins for add-on hardware. Also at the Intel Developer Forum today, the company demonstrated a PC running on Skylake, a new CPU microarchitecture based on the 14nm process used for Broadwell. Intel is pushing to break into both wearable devices and household devices, as it sees both as huge opportunities for growth.
