'All my publications are open source so that everyone in the world can use this information freely.'
The discovery comes from researchers led by The Ohio State university who have recorded GPS measurements that show West Antarctic bedrock is being pushed sideways at rates up to about twelve millimeters--about half an inch--per year.
Wilson leads POLENET an international collaboration that has planted GPS and seismic sensors all over the West Antarctic Ice Sheet.
After all they've been using GPS to observe vertical motion on the continent since the 1990's. They were surprised she said to find the bedrock moving towards regions of greatest ice loss.
The seismic sensors explained why. By timing how fast seismic waves pass through Earth under Antarctica the researchers were able to determine that the mantle regions beneath east and west are very different.

A research team led by conservation biologist Miles Silman will launch two different drones to conduct climate research in the region giving a never-before-seen bird's eye view of one of the most difficult locations in the world to study.
The drones will allow researchers to gather thermal data down to a few centimeters and visible light data down to the sub centimeter level a big improvement over current satellite capabilities.

Both robots are capable of taking pictures of an object from multiple viewpoints. They then use that data to build three-dimensional models that can be studied in the lab. It works in a way that is really quite similar to how a human uses their eyes he said.
Rather than relying on a human operator the drones fly autonomously using global positioning data compass coordinates and onboard stabilization systems.

Bouncing messages around a network and adding a layer of encryption with each bounce takes time and computing power.
If a criminal uses the service to send a malicious message the network expends the same computing power to send that message
Guan's system named THEMIS is designed to minimize the computing power used to send messages and provide a way to track the source of the message should it be thought of as malicious.
By its very design the system avoids expending computing power to send illegal and harmful messages.
By that measurement computing power expended to support criminal activity will also decrease. That's a good thing.

#New micro water sensor can aid growerscrop growers wine grape and other fruit growers food processors and even concrete makers all benefit from water sensors for accurate steady and numerous moisture readings.
But current sensors are large may cost thousands of dollars and often must be read manually.
Now Cornell University researchers have developed a microfluidic water sensor within a fingertip-sized silicon chip that is a hundred times more sensitive than current devices.
The researchers are now completing soil tests and will soon test their design in plants embedding their lab on a chip in the stems of grape vines for example.
They hope to mass produce the sensors for as little as $5 each. In soil or when inserted into a plant stem the chip is fitted with wires that can be hooked up to a card for wireless data transmission
Such inexpensive and accurate sensors can be spaced strategically in plants and soil for accurate measurements in agricultural fields.
While growers can use the sensors to monitor water in soils for their crops civil engineers can embed these chips in concrete to determine optimal moisture levels as the concrete cures.
The sensors make use of microfluidic technology--developed by Abraham Stroock associate professor of chemical and biomolecular engineering--that places a tiny cavity inside the chip.

Data from the sensors were transmitted wirelessly to a computer on the sideline and processed to measure both the linear and rotational head acceleration caused by each impact.

and how much of the center's electricity comes from renewable or low-carbon sources. Adding renewable power to the mix can help reduce a data center's overall emissions by 98 percent
when combined with other strategies but renewables are not the first choice for reducing emissions the analysis shows.
Of these three improving the efficiency of the IT devices is overwhelmingly the most important said Jonathan Koomey a co-author of the study Characteristics of Low-Carbon Data centers published online June 25 in Nature Climate Change.
Server virtualization consolidation and better software can increase utilization to greater than 30 percent and in some cases to be as high as 80 percent said Koomey a research fellow at Stanford university's Steyer-Taylor Center for Energy Policy

Data centers consume about 1. 5 percent of the world's electricity and are responsible for about 0. 5 percent of carbon emissions.
After IT equipment the second major way to reduce greenhouse gas emissions associated with data centers is to improve the efficiency of the buildings that support them.
State-of-the-art data centers have reduced the ratio to about 1 to 0. 1 kwh said study co-author Arman Shehabi of Lawrence Berkeley National Laboratory's Environmental Energy Technologies Division.
and solar power plus green handling of retired equipment can get a typical data center's emissions down 98 percent.
For data centers as for all uses of energy efficiency is always the first thing to do. It's cheapest
So high-energy data centers that pay their utilities a premium for renewable power unnecessarily tie up low-carbon electrons that might otherwise be used to reduce emissions from other customers.
