- Status Of The Higgs Challenge
-
As I reported a couple of times in the course of the last three months, the ATLAS experiment (one of the two all-purpose experiments at the CERN Large Hadron Collider) has launched a challenge to data analyzers around the world. The task is to correctly cl ...

- 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 ...
