Princeton scientists confirm long-held theory about source of sunshine

Scientists are a step closer to understanding sunshine. A monumental experiment buried deep beneath the mountains of Italy has provided Princeton physicists with a clearer understanding of the sun's heart -- and of a mysterious class of subatomic particles born there.

(Let the sun shine in... )

ooh, ooh, ooh, I think I know this one!

The source of sunshine is....the sun?

Star Trek medical device uses ultrasound to seal punctured lungs

A stretcher races through the entrance of a busy hospital. The car-accident victim lies on top and grimaces in pain. While surface injuries looks gruesome, the real medical danger is invisible - internal organ damage caused by being crushed against the steering wheel.

This isn't a scene from Seattle Grace Hospital, the set of the popular television drama Grey's Anatomy, but from its real-life model, Harborview Medical Center. Engineers at the University of Washington are working with Harborview doctors to create new emergency treatments right out of Star Trek: a tricorder type device using high-intensity focused ultrasound rays. This summer, researchers published the first experiment using ultrasound to seal punctured lungs.

Now it’s not just Spiderman that can scale the Empire State Building

Physicists have found the formula for a Spiderman suit. Only recently has man come to understand how spiders and geckos effortlessly scuttle up walls and hang from ceilings but it was doubted that this natural form of adhesion would ever be strong enough to hold the weight of real life Peter Parkers.

For sure!

Yeah, right! We must remember this is PR from somewhere. In practice the durn thing probably also accidently seals wind pipes and heart valves but you ain't gonna find that out til the first 100 or so relatives start suing

Well, that there sonic screwdriver is new technology... On this planet at least.

A heavy subject:
A Better Definition for the Kilogram?

How much is a kilogram? It turns out that nobody can say for sure, at least not in a way that won’t change ever so slightly over time. The official kilogram – a cylinder cast 118 years ago from platinum and iridium and known as the International Prototype Kilogram or “Le Gran K” – has been losing mass, about 50 micrograms at last check.

Argon Conclusion: Researchers Reassess Theories on Formation of Earth’s Atmosphere

Geochemists at Rensselaer Polytechnic Institute are challenging commonly held ideas about how gases are expelled from the Earth. Their theory, which is described in the Sept. 20 issue of the journal Nature, could change the way scientists view the formation of Earth’s atmosphere and those of our distant neighbors, Mars and Venus.

(Argon: this stuff's really a gas!)

Neutrons not so neutral after all, study says

Among atomic particles, the neutron seems the most aptly named: Unlike the positively charged proton or the negatively charged electron, neutrons have a charge of zero.

But new experiments conducted in three particle accelerators suggest the neutron is more like an onion when it comes to electromagnetism: with a negatively charged exterior and interior and a positively charged middle sandwiched between them.

Like an onion? So in addition to having charge, it also has flavor!
