It was another big week for physics as a team of researchers led by Brown University's Vesna Mitrovic found —the results of fifty years of research. Also, a team of cosmologists working on —it represents the most precise and sensitive measurements of the microwave background to date. And a team of researchers at Shanghai University found a . It's different from 2-D and 3-D methods and offers the possibility of better security when used in anti-counterfeiting holographs.

There was news from Saturns' moon as well; one team found that —they shift away from the poles and are upending traditional thinking about the moons' windy atmosphere. Meanwhile, a . They report that it is very similar to clouds that form above the Earth's poles.

In other news, in a truly unique study, a team of —turns out they were mostly vegetarians when training and took in ashes as a tonic. Also, a new phone app, allows blink, point and shoot equation solving and is likely to stir up interest—it allows a smartphone to solve math problems, which could be used for helping to learn, or in some cases to help students cheat on exams. And researchers with the Salk Institute have —good news for the more than 35 million people around the world currently living with the virus. Also of interest, researchers report unearthing —from the femur of a man who died beside the banks of a west Siberian river approximately 45,000 years ago.

And finally, if you have been feeling tired lately, it might interest you to know that —perhaps goofing off sometimes really does help.
