For a mathematician, Joseph Biello spends a lot of time thinking about the weather. But the UC Davis assistant professor isnt looking out the office window. He is using mathematical theory to build a model of the Madden-Julian Oscillation, a tropical weather pattern that influences drought and rainfall in the western U.S.
The Madden-Julian Oscillation was discovered in 1972 when researchers looked closely at meteorological data. It lasts 30 to 60 days and appears as clusters of tropical thunderstorms over the Indian Ocean before sweeping eastward into the Pacific, where it dissipates.
Measured in weeks, the Madden-Julian Oscillation lies in a gray area between short-term weather forecasts and long-term climate studies, said Bryan Weare, a professor of meteorology at UC Davis who also studies the phenomenon. A better understanding of the weather pattern would help with medium-range weather and climate forecasting.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
