New tabletop detector 'sees' single electrons

Magnet-based setup may help detect the elusive mass of neutrinos

23-Apr-2015

MIT physicists have developed a new tabletop particle detector that is able to identify single electrons in a radioactive gas.As the gas decays and gives off electrons, the detector uses a magnet to trap them in a magnetic bottle. A radio antenna then picks up very weak signals emitted by the ...

New detector sniffs out origins of methane

Instrument identifies methane's origins in mines, deep-sea vents, and cows

09-Mar-2015

Methane is a potent greenhouse gas, second only to carbon dioxide in its capacity to trap heat in Earth's atmosphere for a long time. The gas can originate from lakes and swamps, natural-gas pipelines, deep-sea vents, and livestock. Understanding the sources of methane, and how the gas is formed, ...
