California's current earthquake hiatus is an unlikely pause

There have been no major ground rupturing earthquakes along California's three highest slip rate faults in the past 100 years. A new study published in Seismological Research Letters concludes that this current "hiatus" has no precedent in the past 1000 years. | Continue reading

The psychology behind solving cold case homicides

Probing unsolved crimes from years or decades ago is a challenge for any police officer. But the task is made even more difficult because the very term "cold case" puts a dampener on expectations of success, according to a university criminologist whose latest book calls for a ne … | Continue reading
