A new weapon in the Chinese military arsenal is said to be causing a stir in the U.S. Navy: the Dongfeng 21D anti-ship ballistic missile (ASBM). Some experts are calling it a “game changer” because the missile is the first ballistic missile with the capability to take out a moving aircraft carrier. Because it’s ballistic it can travel at incredible speeds: this missile reportedly clocks in close to an astounding Mach 10!
Earth’s supply of helium is dwindling fast.
It is more commonly known as the gas that fills cheap party balloons and makes your voice squeak if you inhale it.

Earth’s resources of helium are being depleted at an astonishing rate, an effect which will spell disaster for hospitals which use it to cool MRI scanners.

Amazing work, folks!
Update: Here’s a nice video slideshow of the launch.
