Saturn's moon Titan might be in for some wild weather as it heads into its spring and summer, if two new models are correct.

Scientists think that as the seasons change in Titan's northern hemisphere, waves could ripple across the moon's hydrocarbon seas, and hurricanes could begin to swirl over these areas, too. The model predicting waves tries to explain data from the moon obtained so far by NASA's Cassini spacecraft. Both models help mission team members plan when and where to look for unusual atmospheric disturbances as Titan summer approaches.

Ernie Pyle, the iconic embedded World War II embedded journalist killed by Japanese machine gun fire in 1945, made famous the adage, "There are no atheists in foxholes." 

He was making a point that it's better to be safe than sorry when your life is on the line - not letting the Devil get you cornered, he wrote, was the justification for a soldier who dug round foxholes. Atheists are a tiny minority anyway and there are even fewer in a war zone, Pyle felt. And he knew more soldiers than perhaps any journalist ever will.

A 12-year study (1999 to 2010) analyzed fatality reductions in bicycle-car collisions to determine the effect of mandatory helmet laws. 16 states had bike helmet laws in the beginning or the study. The researchers identified all relevant fatalities, totaling 1612, in states with and without bike helmet laws.
  

Relevance was determined by adjusting for factors previously associated with rates of motor vehicle fatalities (elderly driver licensure laws, legal blood alcohol limit and household income) and, among those, they found that the adjusted fatality rate was significantly lower in states with helmet laws. On average, 900 people die annually in bicycle-motor vehicle collisions — three quarters of those are from head injuries. 

Is the obesity epidemic due to the addictive qualities in food or that a lot more food is cheap and plentiful than ever before in history?

A paper presented at the 2013 Canadian Neuroscience Meeting, the annual meeting of the Canadian Association for Neuroscience - Association Canadienne des Neurosciences (CAN-ACN), says the problem is addiction rather than food wealth - the authors claim that high-fructose corn syrup can cause behavioral reactions in rats similar to those produced by drugs of abuse such as cocaine.  It's the "Food Addiction" hypothesis that has recently become popular, which posits that we could be addicted to food just like drugs.  

Sourcing of ancient artifacts has gotten a new advance.

While at the University of Sheffield in the years 1965–1972, Professor Lord Colin Renfrew developed a technique that matched stone tools made of obsidian, naturally occurring glass, to their volcanic origins based on their chemical fingerprints. It was considered one of the greatest successes in scientific archeology, matching artifacts to specific volcanoes was a significant leap forward in understanding trade, contact, and cultural change in the ancient world.

It is often believed that mega-events like the Olympics are good for a city or country. Many of the benefits are implied but they still get a monetary value attached when selling it to the public; 'leadership','world-stage', etc. The hangover that occurs economically afterward often leaves host countries wondering who did the math.

But if you are a small charity relying on corporate donations, it may be a good idea to get behind all of those taxpayers underwriting big occasions. Even smaller events like political conventions, and certainly the Super Bowl, deliver a morale-boost in the form of hometown pride and that translates into corporate largess, says a new paper that refutes beliefs that corporate philanthropy remains stable even during high-profile activities.
