New Scientist Update II

From the July 8th and 19th August Issues

July 8th

- It seems possible to 'pinch' off a second universe in a physics lab like setting. Personally I think this is complete nonsense but not according to NS.

- The universe apparently has a density of 10E-25 kg/cubic meter. Using these number scientists determined that the mass of the universe is much less than expected.

- A scientist discovers the mystery behind magic sand.

- Liked this one- since I am enthralled with extra-dimensions.
- Artificial sun may reveal extra dimensions

- This article on the Quantum weirdness of Graphene makes this issue worth buying.
