Will Do Peer Review- For Money

Preparing the documents needed for an exam for a career advancement, to a scientist like me, is something like putting order in a messy garage. Leave alone my desk, which is indeed in a horrific messy state- papers stratified and thrown around with absolut ...

Wave-Particle Duality Principle Remains Safe And Sound

Wave-particle duality suggests that elementary particles, like electrons and photons, cannot be completely described as either waves or particles, because they exhibit both types of properties. In the double-slit experiment, observing a photon pass throug ...

The Quote Of The Week- Neutrino Mass Hierarchy and Matter Effects

Interaction with matter changes the neutrino mixing and effective mass splitting in a way that depends on the mass hierarchy. Consequently, results of oscillations and flavor conversion are different for the two hierarchies. Sensitivity to the mass hierar ...

Holographic Noise Speculation: Maybe You Are A 2-D Hologram

The Holometer, an experiment at Fermi National Accelerator Laboratory, has started collecting data but researchers are not going to wait to start their media blitz; they are throwing out  mind-bending speculation, like that perhaps we live in a hologram. ...

Proton-Proton Fusion: Looking Into The Heart Of The Sun

Using the Borexino instrument, located deep beneath Italy's Apennine Mountains and one of the most sensitive neutrino detectors on the planet, an international team of physicists has directly detected neutrinos created by the "keystone" pro ...

Schrödinger's Picture: Researchers Take An Image Without Ever Detecting Light

Here is something counter-intuitive: researchers have developed a new quantum imaging technique in which the image has been obtained without ever detecting the light that was used to illuminate the imaged object, while the light revealing the image never ...

How The Higgs Became The Target Of Run 2 At The Tevatron

Until the second half of the nineties, when the LEP collider started to be upgraded to investigate higher centre-of-mass energies of electron-positron collisions than those until then produced at the Z mass, the Higgs boson was not the main focus of experi ...

The Graph Of The Week: No Dark Photons Found By ATLAS Lepton Jets Search

Among the viable extensions of the standard model, an intriguing class of models involve the concept of a "hidden sector" of new particles only weakly coupled to the standard model one. These particles could be produced in the decay of heavy stan ...

Is This Dark Matter?

Because detectable mass only makes up about 5 percent of the universe- and the universe is expanding faster now than in the past- a rethink of mass and gravity has been required. The umbrella term for this mass that must exist, but can't be detected, ...
