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.

Moderate to severe diarrhea (MSD) is a major cause of childhood mortality in developing countries and ranks as one of the top four causes of death among young children in sub-Saharan Africa and South Asia. In a finding that may one day help control this major cause of death among children in developing countries, a team has identified microorganisms that may trigger diarrheal disease and others that may protect against it.

These microbes were not widely linked to the condition previously and a much better understanding of these interactions is important because they could lead to possible dietary interventions.  

If your glass is half full, you recognize that in recent geological history, 90,000 of every 100,000 years have been ice ages, and it's been 12,000 years since the last one. In that light, global warming might be a good thing.

Tesla Motors CEO and Tony Stark do-alike Elon Musk recently raised a great deal of consternation by releasing Tesla’s patents for anyone to use “in good faith”.  Amid the hue and cry of befuddled business analysts, multiple theories bubbled up.

Writing in the Proceedings of the National Academy of Sciences, scientists have shown regulatory proteins in the nucleus to adopt a kind of “Tom Sawyer” behavior when it comes to the work of initiating gene activation. 

Transcription factors are proteins that orchestrate the flow of genetic information from DNA to messenger RNA (mRNA) and the results show how transcription factors (TFs) activate mRNA synthesis of a gene, and leave the scene – in a model termed “hit-and-run” transcription.
