An interesting article about the discovery of a new type of electrical device. Based on the equations relating charge and magnetism, Leon Chua deduced that the mathematics of electric circuits was missing an element (one that directly relates charge to magnetic flux) - he dubbed the missing element a memristor.
Now scientists believe they have found a physical device that has this effect ... at nanoscales. The device could have some amazing applications for computation.

A high altitude balloon flight in 2006 has reveals a very strong source of background radiation from an unknown source.
Add this to the Dark Matter, and Dark Energy mysteries, and we may have some sort of new cosmological model?

Strange but interesting - stratified warm water layer at the surface can make it very difficult to swim (and even cuts the speed of power boats).

Alan Boyle narrated video explains some of the details of Yuri Gagarin's flight. I hadn't realized he ejected from the capsule at 23,000 feet - and parachuted to the ground.

On March 18th, a very large gamma-ray and optical burst occurred. The source is reported as being 7 billion light years - yet it would have been visible to the naked eye for several minutes before dimming again.
Due to automated systems for sky monitoring, coupled with gamma-ray burst alerts coming from satellites, the even was recorded here in the optical spectrum.
