No pause in global warming in the past 100 years

Global warming has been attributed to persistent increases in atmospheric greenhouse gasses (GHGs), especially in CO2, since 1870, the beginning of the Industrial Revolution. Nevertheless, the upward trend in global mean ...

Frequency stabilization in nonlinear nanomechanical oscillators

Using Center for Nanoscale Materials (CNM) expertise in the design and fabrication of micro- and nanoscale devices, a new strategy for engineering low-frequency noise oscillators capitalizes on the intrinsic nonlinear phenomena ...

Terahertz waves from electrons oscillating in liquid water

Ionization of water molecules by light generates free electrons in liquid water. After generation, the so-called solvated electron is formed, a localized electron surrounded by a shell of water molecules. In the ultrafast ...

Effect of ocean temperature on southwestern US climate analyzed

Researchers have analyzed the relationship between a natural phenomenon in the North Atlantic and the temperature and precipitation patterns in the American Southwest. They concluded that only part of the recent temperature ...
