Where Has The Antimatter Gone: Physics at CERN

By Richard Gray, Science Correspondent of  The Telegraph

Large Hadron Collider: results hint at where all the antimatter has gone.

Scientists at the Large Hadron Collider have seen tantalising clues that may help to explain why the universe around us is made from matter rather than its opposite form antimatter.

Researchers hunting for antimatter at CERN, the city sized science complex where the LHC is based, have found that particles of matter decay differently from their antimatter cousins.

Current theories suggest that after the Big Bang that created the universe, there were equal amounts of matter and antimatter created.

However, when particles of matter meet their antimatter opposites, they annihilate each other with an explosion of energy. ………………..

Lalarukh Hussain: A rare woman

Lalarukh Hussain died of brain hemorrhage on Wednesday, March 20, 2013  in Los Angeles. She was “Lali” for those close to her. No one who met her can forget the eversmiling fresh face of hers.

She joined the left-wing National Students Federation in the late 1960s and participated in the movement against Gen. Ayub Khan’s military dictatorship. She was a high quality journalist and worked for several newspapers and magazines of Pakistan. In her journalistic career she became editor of a couple of magazines. She earned her degree in journalism from the University of Karachi in 1972.

She was active member of Karachi Union of Journalists (KUJ) and PFUJ. During the military dictatorship of Gen. Ziaul Haq in  1978 she was  in the forefront of the  historic movement of journalists for  press freedom spearheaded by PFUJ. She joined the hunger strike.  She, in a brave manner, courted arrest with her one year old child.

She participated in the struggle of factory workers, teachers  and women for their rights. Her life will always inspire those who  fight against dictatorship and tyranny for the peoples’ rights,  justice and democracy.

Higg’s Boson Discovered?:

Higgs boson: scientists confident they have discovered the ‘God particle’

11:04AM GMT 14 Mar 2013

CERN, the European Organisation for Nuclear Research, announced today that after extensive testing it was “looking more and more” like the particle which they discovered last year was the Higgs boson.

Finding the Higgs plugs a gaping hole in the Standard Model of physics, the theory that describes all the particles, forces and interactions that make up the universe.

Today the collaborating scientists from ATLAS and CMS announced their results at the Moriond

Conference, in La Thuile, Italy, further confirming the “magnificent” discovery.

“The preliminary results with the full 2012 data set are magnificent and to me it is clear that we are dealing with a Higgs boson though we still have a long way to go to know what kind of Higgs boson it is.” said CMS

spokesperson Joe Incandela.  ………..

Supercomputers used to supercharge antioxidants
The future of keeping ageing-related diseases at bay lies with the supercomputer according to scientists from the ARC Centre of Excellence for Free Radical Chemistry and Biotechnology at the University of Sydney.
The research, led by Professor Leo Radom from the University’s School of Chemistry, and Dr Amir Karton, University of Western Australia, has used sophisticated quantum chemistry and powerful supercomputers to design improved antioxidants which will help stave off ageing-related diseases such as heart disease, cancer, diabetes, and Alzheimer’s disease.

Impressions of Gaza: Noam Chomsky

A gripping article by Noam Chomsky describing what is happening in Gaza that you must read. 

Even a single night in jail is enough to give a taste of what it means to be under the total control of some external force. And it hardly takes more than a day in Gaza to begin to appreciate what it must be like to try to survive in the world’s largest open-air prison, where a million and a half people, in the most densely populated area of the world, are constantly subject to random and often savage terror and arbitrary punishment, with no purpose other than to humiliate and degrade, and with the further goal of ensuring that Palestinian hopes for a decent future will be crushed and that the overwhelming global support for a diplomatic settlement that will grant these rights will be nullified. …………
