Tsunami earthquakes are rare but they happen at relatively shallow depths in the ocean. So while are small in terms of their magnitude, they create very large tsunamis, with some earthquakes that only measure 5.6 on the Richter scale generating waves that reach up to 30 feet high when they hit the shore. 

A global network of seismometers enables researchers to detect even the smallest earthquakes. However, the challenge has been to determine which small magnitude events are likely to cause large tsunamis.  New research has revealed the causes and warning signs of these rare tsunami earthquakes, which may lead to improved detection measures. 

Climate change is predicted to have major impacts on the many species that call our rocky shorelines home.

Species living in these intertidal habitats, which spend half their day exposed to air and the other half submerged by water, could subjected to a double whammy if air and water temperatures rise. 

Though cultural advocates invoke cancer for their causes, genetics is the dominant risk factor in common breast, prostate and colorectal cancers. 

It's no secret that people who are tired don't perform well but a new study tackles the impact of being a morning person or a night owl on driving performance.

By measuring people when they are out of sync with their "chronotype" whether they are physiologically more active during the day or night - influences driving performance, and which chronotype performs better at a non-optimal time.

Facebook has more than 1.23 billion active users. Most of them are not actually friends with each other and because they are not friends with each other, they feel pushy recommending products or services. They're fine hammering on politics and religion, but endorsing a car looks too corporate.

That's bad news for Facebook's business model, which has so far convinced advertisers they need to spend money. Facebook has tinkered with everything from forcing contributors to pay to have their posts seen by people on their list to pushing ads more aggressively based on everything from browser cookies to media use on the PCs of members.
