Quantum computing advances with control of entanglement
When the quantum computer was imagined 30 years ago, it was revered for its potential to quickly and accurately complete practical tasks often considered impossible for mere humans and for conventional computers. But, there was one big catch: Tiny-scale quantum effects fall apart too easily to be practical for reliably powering computers.
Now, a team of scientists in Japan may have overcome this obstacle. Using laser light, they have developed a precise, continuous control technology giving 60 times more success than previous efforts in sustaining the lifetime of "qubits," the unit that quantum computers encode. In particular, the researchers have shown that they can continue to create a quantum behavior known as the entangled state—entangling more than one million different physical systems, a world record that was only limited in their investigation by data storage space.

SpaceX’s planned Mars rocket will be reused 1,000 times
SpaceX CEO Elon Musk has unveiled the design for the giant rocket booster he wants to build in order to colonize Mars. It is part of what SpaceX is referring to as the "Mars Vehicle" — the rocket booster and the Mars spaceship combined — and Musk announced it on stage in Guadalajara, Mexico at the 67th International Astronautical Conference.
