We've done articles on rainbows, and double rainbows and even showed you how to make a rainbow appear for that special someone - but have you ever seen a triple rainbow?

It makes environmental activists crazy, in that 'believe scientists when science agrees with us but scientists are out to kill us when science doesn't agree' kind of way, but a large study of U.S. adults found that the more science they knew and the more independent they were, the less they were worried about climate change.

"Search.  The final frontier.  These are the voyages of the frustrated Web surfer.  Its five-year mission: To explore strange new content, to seek out new ideas and new expressions.  To boldly know when someone is pulling our leg or being sincere." I'm not waiting for William Shatner to record that monologue but there are days when I can almost hear it rolling about in my head.  Search is such a universal thing for people -- we were born to it.  We resonate with memories of failed searches every time we hear someone gasp, "What did I do with my keys?"

Why would anyone build a Tubesat when the Cubesat open standard tends to dominate the picosatellite world?  Well, first, there's only been a bit over a dozen Cubesats, so it's a wide open field.  Second, the Tubesat design is actually a kit, including schematics that are pre-integrated, rather than being an open spec like Cubesat. 
In some ways, it's a little odd to compare them, much like you can't really compare an iPhone to an Android smartphone.  iPhones are a device; Android is an operating system used in over 75 different devices.  Similarly, Tubesat is a device; Cubesat is a specification that people fit their own ideas into.  Different approaches.

According to the Centers for Disease Control and Prevention, 33.8 percent of American adults are obese. placing them at increased risk for type 2 diabetes, coronary heart disease, stroke, and certain cancers.  That's a lot of fat, but not all fat is bad.

When we picture body fat, what we are thinking of is white fat but another type, brown fat, does more - it burns body fat.  It was once believed that brown fat disappeared after infancy but recent advances in imaging technology led to its rediscovery in adult humans

Women often gain weight as they age and a new study in Cell Metabolism says the sex hormone estrogen, and estrogen receptor-α (ERα) has an important yet under-appreciated role in those bigger waistlines. 

Musical cartoons can boost verbal intelligence?  We'll hiatus Science 2.0 and start watching "Phineas&Ferb" right now.

Researchers writing in Psychological Science say pre-schoolers improved their skill after only 20 days of classroom instruction using their interactive, music-based cognitive training cartoons.

Tomorrow I will fly to Frascati, where are the headquarters of INFN, the italian institute for nuclear physics. I will attend to an event there, called "Incontri di Fisica" (Physics meetings), where high-school teachers meet researchers and receive training, as well as discuss ways to improve science education and popularization in schools and outside.

I will be discussing the subject of "Science popularization with blogs" on Wednesday afternoon and then, two days later, I will be the last speaker with another short talk, where I will try to summarize some ideas on the matter. And you might help for this latter presentation.

A daily supplement to reduce diabetes?   Maybe.

Researchers writing in Cell Metabolism show they have have restored normal blood sugar metabolism in diabetic mice using, nicotinamide mononucleotide(NMN), a compound the body makes naturally and which plays a vital role in how cells use energy.

All cells in the body make NMN in a chain of reactions leading to production of NAD, a vital molecule that harvests energy from nutrients and puts it into a form cells can use. Among other things, NAD activates a protein called SIRT1 that has been shown to promote healthy metabolism throughout the body, from the pancreas to the liver to muscle and fat tissue.

This year’s Nobel Prize in physics goes to Saul Perlmutter, who shares it with Adam Riess and Brian P. Schmidt, all having been vital in the discovery of that the universe’s expansion is speeding up; research that was done during the 1990s.

Several science bloggers opined that maybe work on quantum entanglement was more deserving, and they have a point, but if the wider impact of scientific issues is at play in the considerations that lead to awarding the Nobel Prize, the decision today was a good one in that regard.
