Nature publishes new findings that could lead to improved earthquake assessments
Seismologists have long known that the buildup of forces along fault zones cause the physical properties of rock and sediments to change deep inside the Earth, at the level where earthquakes occur. Based upon new findings, researchers believe they may be able to design active seismic monitoring systems that continually monitor these subtle changes, looking for telltale signs of an impending earthquake.
The new findings, published in the Dec. 4 issue of the journal Nature, are based on an extensive study of data collected between 1987 and 1997 by ultrasensitive borehole seismometers along the Parkfield segment of the San Andreas fault in central California. By comparing seismograms from a series of minor earthquakes that occurred both before and after a "slow" earthquake at Parkfield in 1993, the researchers were able to detect subtle changes in the level of stress along the fault zone that were caused by this event.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
