The Kaiser effect, which is known as a stress memory effect, predicts that seismic events occur only when the previous maximum stress is exceeded. However, the Kaiser effect has only been tested at room temperature in laboratories. Here, we performed deformation experiments on natural olivine at high pressures and high temperatures. We have successfully confirmed a stress memory effect in strongly deformed olivine at high pressures and high temperatures.

Surveying nearby galaxies in the process of merging with other galaxies, astronomers have identified massive, dense star factories, unlike any found in the Milky Way. The findings provide a rare glimpse into processes shaping galaxies in the very early universe and possibly the Milky Way a few billion years from now. 

Data from NASA’s James Webb Space Telescope has revealed dozens of small galaxies that played a starring role in a cosmic makeover that transformed the early universe into the one we know today.

The SETI Institute is pleased to announce Dr. Karen I. Perez as the inaugural recipient of the William J. Welch Postdoctoral Fellowship at the SETI Institute. Beginning in the Fall of 2025, Perez will develop real-time, machine-learning-enabled and GPU-accelerated analysis pipelines for detecting single-pulse transients, as well as narrowband and broadband technosignatures, using the Allen Telescope Array (ATA) in Hat Creek, CA and other telescopes around the world.

Her research will bridge science and engineering, advancing the field of radio astronomy through the integration of NVIDIA accelerator technology, which is crucial for advancing the SETI Institute's data-intensive search for signals from intelligent life.
