It won't exactly set off a Blu-ray versus HD-DVD cultural firestorm, but there is an alternative to 3-D printing. And it's better in many ways. 

Pop-up assembly relies on compression buckling. If that sounds like one of children's books, with the little structures that fold out when opened, that's because those are a good analog. Pop-up fabrication starts as a flat two-dimensional structure and 'pops up' into a more complex 3-D structure. Using a variety of advanced materials, including silicon, the researchers behind it have produced more than 40 different geometric designs, including shapes resembling a peacock, flower, starburst, table, basket, tent and starfish.

So why is it better than 3-D printing? 

Games have been test beds for new ideas in Artificial Intelligence (AI) since computers came on the scene and there have been significant milestones - Deep Blue sort of defeated Kasparov in chess and Watson sort of defeated Jennings and Rutter on Jeopardy! 

But solving a game is a lot tougher than defeating a player, though researchers in the Computer Poker Research Group at the University of Alberta in Canada say they have essentially solved heads-up limit hold'em poker. 

In an interstellar race against time, astronomers measured the space-time warp in the gravity of a binary star and determined the mass of a neutron star just before it vanished from view.

The researchers measured the masses of both stars in binary pulsar system J1906. The pulsar spins and emits a lighthouse-like beam of radio waves every 144 milliseconds. It orbits its companion star in a little under four hours.  The mass of only a handful of double neutron stars have ever been measured, with J1906 being the youngest. It is located about 25,000 light years from Earth. 

80 percent of current coal reserves, 50 percent of gas reserves and 33 percent of oil reserves should remain in the ground by 2050 to avoid the 2°C target established by the Intergovernmental Panel on Climate Change and used as a benchmark by policy makers, according to a new estimate.

So much for that Peak Oil of 1992. We need to worry about Oil Glut instead.

The paper identifies the geographic location of existing reserves that should remain unused - it's no secret that is China, Russia and the United States, along with 260 billion barrels oil reserves in the Middle East. The Middle East should also leave over 60% of its gas reserves in the ground.

A new report by the National Research Council offers guidance to schools on necessary steps for putting the Next Generation Science Standards (NGSS) into practice over the next decade.

Next Generation Science Standards were drawn from A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas, a 2011 Research Council report. Next Generation Science Standards. The standards are based on the ideas that science and engineering involve both knowing and doing; that developing rich, conceptual understanding is more productive for future learning than simply memorizing discrete facts; and learning experiences should be designed with coherent progressions over multiple years.

You may feel safe working at the coffee house because you are not using their public Wi-Fi connection. Think again.

And that smartphone is even more vulnerable to snooping.

The new breed of coffee shop hackers can see what you're doing by analyzing the low-power electronic signals your laptop or smartphone emits - even when it's not connected to the Internet. 

The race is on to plug these information 'leaks' but the first challenge is finding out where they originate. To help, Georgia Institute of Technology engineers have developed a metric for measuring the strength of the leaks - known technically as "side-channel signal" - to help prioritize security efforts.
