Summer Flukes Inspire Creative Theorists

Today the Cornell arxiv features a paper by J. Aguilar Saavedra and F. Jouaquim, titled " A closer look at the possible CMS signal of a new gauge boson ". As I read the title I initially felt somewhat lost, as being a CMS member I usually know ab ...

Electron's Quantum Behavior Recorded

A team of researchers has developed a technique to record the quantum mechanical behavior of an individual electron- contained within a nanoscale defect in diamond. Their technique uses ultrafast pulses of laser light both to control the defect's ent ...

The Periodic Diet

It is a well-known fact that given the availability of food, we eat far more than what would be healthy for our body. Obesity has become a plague in many countries, and the fact that it correlates very tightly with a decreased life expectancy is not a rand ...

Galileons And Ghostly Degrees Of Freedom

There has been discussion among cosmologists about galileons, a hypothetical class of effective scalar fields which are extremely universal and arise generically in describing the short distance behavior of the new degrees of freedom introduced during the ...

Tight Constraints On Dark Matter From CMS

Although now widely accepted as the most natural explanation of the observed features of the universe around us, dark matter remains a highly mysterious entity to this day. There are literally dozens of possible candidates to explain its nature, wide-rangi ...

MRI For A Quantum Simulation

Magnetic resonance imaging (MRI) is the medical application of nuclear magnetic resonance spectroscopy and a powerful diagnostic tool. It works by resonantly exciting hydrogen atoms and measuring the relaxation time-- different materials return to equilibr ...

Have Strange Baryons Been Found?

Can math be evidence? Not ordinarily, but recent calculations are compelling because they show that particles predicted by the theory of quark-gluon interactions but never observed are being produced in heavy-ion collisions at the Relativistic Heavy Ion C ...

Nuclear Magnetic Resonance Using Earth's Magnetic Field

Earth's magnetic field, a familiar directional indicator over long distances, is routinely probed in applications ranging from geology to archeology, and now it has provided the basis for a technique which could characterize the chemical composition ...

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 ...
