No WIMPS in the Xenon
It is a strange headline – No WIMPS in the Xenon, but then Dark Matter is strange. It supposedly must exist, in fact, it makes up 25% of the material in the universe. However, it has never been seen. Not seen even by the latest super high sensitivity detector project called XENON100. Located at the [...]

Physics: A smaller proton, a big challenge
The proton is one of the fundamental components of the atom. For a long time scientists have believed it to be 0.8768 femtometers in size (a femtometer is one quadrillionth of a meter). Now, it looks like they may have been wrong, the size is 0.84184 femtometers. In a way, the discrepancy is very small…as [...]

A neutrino oscillates, wounds Standard Model
This piece of news, the importance of which is disguised by the colorful name chameleon neutrino, should start with the concluding paragraph of the press release from CERN, the European nuclear studies center: While closing a chapter on understanding the nature of neutrinos, the observation of neutrino oscillations is strong evidence for new physics. In [...]

Large Hadron Collider is smashing
For most normal scientific equipment the event of its ‘working’ isn’t news. The Large Hadron Collider (LHC) isn’t a normal piece of scientific equipment, of course. It’s the world’s largest, most expensive, most storied, most plagued, most vilified, most misunderstood, most hoped for, and potentially important piece of scientific equipment. So it’s worthy of being [...]

Looking at the strange face of antimatter
Scarcely three weeks ago, it was reported that the Relativistic Heavy Ion Collider (RHIC) at the Brookhaven National Laboratory had achieved the all time (laboratory) high temperature record of 4 trillion degrees Centigrade. [SciTechStory: Taking the temperature of the Big Bang + milliseconds] The significance was that in colliding atoms of gold and producing such [...]

Large Hadron Collider delivers collisions
Congratulations are in order for the CERN Large Hadron Collider (LHC). After a prolonged, arduous gestation that ended on Monday (November 23, 2009), the first atomic particle collisions were recorded. Having finally got its protons in order, it’s now on to the lengthy testing and gradual ramping-up of the acceleration speed. Sometime next year, the [...]
