Do pencils point to the Holy Grail of physics?
Flat, parallel sheets of carbon atoms in the graphite of pencil lead have been peeled apart by the scientists to yield a sheet a single atom thick that has peculiar properties which made the fundamental feat possible.
…Today, in the journal Science, Prof Andre Geim of Manchester University and his colleagues at The University of Minho in Portugal, say they have used [the material] to measure an important and enigmatic fundamental constant of nature – the fine structure constant.
Working with Rahul Nair and Peter Blake he made large suspended membranes of graphene so that one can easily see light passing through this thinnest of all materials.
The 2.3 per cent of light that it absorbed could then be used to calculate the constant, which shows the interaction between very fast moving electrical charges in the material and light, and it is close to 1/137.” (Telegraph.UK)

Would Mugabe Relinquish in Return for Amnesty?
|
The Guardian reports: “Following the party’s electoral reverses, senior aides to the Zimbabwean president approached the MDC.
They said Mugabe was prepared to step down in return for an amnesty from prosecution for crimes such as the Matebeleland massacres in the 1980s and other guarantees. However, it was unclear whether the approach was a delaying tactic while Mugabe weighed up his options under considerable pressure from different factions within Zanu-PF’s politburo.” |

Time to Stop Caricaturing Chimps

“They have been used to sell everything from tea bags to bicycles and designer watches but the days of showing chimpanzees in TV commercials could be numbered, if a group of leading scientists gets its way.
The primatologists, who include the world-famous Jane Goodall, have attacked the advertising industry for exploiting chimps as ‘frivolous subhumans’ who can be viewed as objects of fun and ridicule for the sake of commercial gain. Dressing up chimps in human clothes or making them perform everyday activities gives people the impression that they are not a species in danger of extinction…” (Independent.UK) |

Marian Wright Edelman: Honoring King is Not Enough
|
“Too many of us would rather celebrate than follow Dr. King. Some of us have enshrined Dr. King the dreamer, but have ignored Dr. King the disturber of all unjust peace. Many celebrate King the orator, but ignore his words and warnings about the need for reordering the misguided values and priorities he believed to be the seeds of America’s downfall. Many remember King the vocal opponent of violence, but not King who called for massive nonviolent civil disobedience to challenge the stockpiling of weapons of death and the wars they fuel.” (Huffington Post)

Josh Marshall: “As I’ve noted here before, should Obama be the nominee, we’re going to see a GOP assault very similar to what hit Gore and Kerry — Obama thinks he’s better than you ordinary Joes, and he thinks patriotism is for rubes. Get ready.” (Talking Points Memo)

“None of … the grimness on the front page today will matter a bit… if two men pursuing a lawsuit in federal court in Hawaii turn out to be right. They think a giant particle accelerator that will begin smashing protons together outside Geneva this summer might produce a black hole or something else that will spell the end of the Earth — and maybe the universe. Scientists say that is very unlikely — though they have done some checking just to make sure.” (New York Times [thanks, Mark] )
