- The Cause of High Blood Pressure Revealed By Computer Modelling
Computer simulations show that high blood pressure can be entirely explained by arterial stiffening as we age, say researchers
- Has Big Data Made Anonymity Impossible?
As digital data expands, anonymity may become a mathematical impossibility.
In 1995, the European Union introduced privacy legislation that defined “personal data” as any information that could identify a person, directly or indirectly. The legislators were apparently thinking of things like documents with an identification number, and they wanted them protected just as if they carried your name.
- Wind Turbines, Battery Included, Can Keep Power Supplies Stable
Advances like GE’s new hybrid wind turbines could make renewable energy more practical.
GE recently sold the first of a new line of “hybrid” wind turbines that comes with a battery attached. The turbine’s battery can store the equivalent of less than one minute of the turbine operating at full power. But, by pairing the battery with advanced wind-forecasting algorithms, wind farm operators could guarantee a certain amount of power output for up to an hour.
- Why It’s Okay that Tesla Makes Cars for Rich People
Tesla’s innovations could make EVs more competitive.
The U.S. Department of Energy has been criticized for loaning money to Tesla Motors because the company makes cars that only rich people can afford. That’s probably part of the reason Elon Musk, Tesla’s CEO, made such a big deal last week in saying that, with a new payment plan, and figuring in savings from gas prices, about 10 percent of the U.S. population can afford a new Model S, up from about 1 percent without the plan.
- How to Avoid Another Flash Crash
How to monitor an incredibly complicated, increasingly automated system that thrives on secrecy.
Today marks the three-year anniversary of the 2010 Flash Crash, when the U.S. stock market lost 1,000 points in a matter of minutes before recovering most of these loses a few minutes later.
