Geneva, 14 July 2015. Today, the LHCb experiment at CERN’s Large Hadron Collider has reported the discovery of a class of particles known as pentaquarks. The collaboration has submitted a paper reporting these findings to the journal Physical Review Letters. “The pentaquark is not just any new particle,” said LHCb spokesperson Guy Wilkinson. “It represents a way to aggregate quarks, namely the fundamental constituents of ordinary protons and neutrons, in a pattern that has never been observed before in over fifty years of experimental searches. Studying its properties may allow us to understand better how ordinary matter, the protons and neutrons from which we’re all made, is constituted.”
…………. The Higgs boson, a sub-atomic particle that pervades the Universe, is crucial to something called the Standard Model, which attempts to unite the building blocks of matter with three of the four known forces of nature – only gravity is left out.
Until Peter Higgs, Francois Englert and Robert Brout came along with their theory in 1964, the Standard Model was under threat because it could not explain how sub-atomic particles – and hence all matter in the Universe – have mass and therefore structure.
The proposition of a sub-atomic particle that creates a field through which other particles interact was the missing piece of the puzzle. It is this interaction between matter and the field created by the Higgs boson that imparts mass to matter. ………..

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. ………………..
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
Scientists working at the world’s biggest atom smasher near Geneva have announced the discovery of a new subatomic particle that looks remarkably like the long-sought Higgs boson. Sometimes called the “God particle” because its existence is fundamental to the creation of the universe, the hunt for the Higgs involved thousands of scientists from all over the world.
Scientists developingdevice to ‘hack’ into brain of Stephen Hawking Updated 06:42 PM Jun 26, 2012
LONDON – Stephen Hawking is testing out a groundbreaking device to allow him to communicate through brain waves in a project that scientists have likened to “hacking into his brain”.Dr Hawking, 70, has been working with scientists at Standford University who are developing a the iBrain – a tool which picks up brain waves and communicates them via a computer.The scientist, who has motor neuron disease and lost the power of speech nearly 30 years ago, currently uses a computer to communicate but is losing the ability as the condition worsens, the Daily Telegraph reported. ………

Faster-than-light neutrinos? Why nobody is surprised it might be an error.
Last year, European particle physicists observed neutrinos apparently traveling faster than the speed of light. But now it seems that it was a bad measurement, which is no surprise to the physics community. ……..
‘They’ll find the God particle by summer.’ And Peter Higgs should knowRenowned physicist Professor Peter Higgs gives a rare interview to Jenny Fyall as he receives the Edinburgh AwardProfessor Peter Higgs told The Scotsman he thought scientists at Cern working with the Large Hadron Collider would find evidence that the elusive particle exists within a matter of months.The acclaimed 82-year-old theoretical physicist came up with the now famous theory in 1964 which provides an explanation for the origins of mass as a property of matter.………………………………………………………..
