Chinese scientists made calculations and predict that a new 2D allotrope of carbon based in a pentagonal form resembling an common pavement in the streets of cairo can be synthesized, they call this new form penta-graphene from the announcement in the Chemistry World they say: "The team found that not only should a pentagon-containing version of graphene be fairly stable, it should also be stronger than conventional graphene and be able to withstand higher temperatures, up to 730C. It would also be a natural semiconductor, unlike conventional graphene, which is a highly efficient conductor and has to be chemically modified to turn it into a semiconductor."

The amount the U.S. military spends annually on air conditioning in Iraq and Afghanistan: $20.2 billion.
That's more than NASA's budget. It's more than BP has paid so far for damage during the Gulf oil spill. It's what the G-8 has pledged to help foster new democracies in Egypt and Tunisia.

Netx big future blog post an interesting article about the Indian university of Bengal,reporting (pdf) possible superconducting effect in ambient room temperatures. from the article:
We report the observation of an exceptionally large room-temperature electrical conductivity in silver and aluminum layers deposited on a lead zirconate titanate (PZT) substrate. The surface resistance of the silver-coated samples also shows a sharp change near 313 K. The results are strongly suggestive of a superconductive interfacial layer, and have been interpreted in the framework of Bose-Einstein condensation of bipolarons as the suggested mechanism for high-temperature superconductivity in cuprates.
