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…

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…

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…

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…

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…

After spending many years thinking about and writing about quantum gravity theories both mine and those of others I have come to the conclusion that a theory like M-Theory is the way to go.  …

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…

Tomorrow's commercial refrigeration systems, such as those in supermarkets, could be cooled by carbon dioxide instead of hydrofluorocarbons. Hydrofluorocarbons are a greenhouse gas that is nearly 4,…

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…

As a quantum state collapses from a quantum superposition to a classical state or a different superposition, it will follow a path known as a quantum trajectory. For each start and end state there is…
