DeSimone and his team have been working with PFPE for years, and during their research, the crew found that another polymer electrolyte, polyethylen glycol or PEG, and PFPE could combine to dissolve salt, and potentially function as an electrolyte. When his team attached the PFPE to dimethyl carbonate, an electrolyte traditionally used in batteries, the resulting PFPE-DMC was a polymer that could move a battery's ions with insane levels of efficiency while remaining stable.

Patterning the glass can make it up to 200 times more resistant to forming cracks

Problem solved.

Those would also work very well to keep the Kaiju's out..

Good point!

On the way towards autonomous flying deliveries and building a Megazord formation!

A 7x7x3m large unfolding structure from the car trunk. "Before the design is ready to roll, the team still needs to tune up the solar components, a challenge made more difficult by the pavilion's inherent mobility, making it impossible to gauge how sunlight will fall on it."

Earth has had a ring of particles (similar to Saturn's) for a short period of time. And it is manmade.

Creepy but cool

High energy gamma rays are shown to be bent slightly by specialized lenses. The effect is likely due to pair-creation close to the atomic nuclei in the material.

Video shows how easy the process is and how cool the results look. Does anybody know a potential scientific application for such image processing?

this is very impressive indeed ... looks like the manual steps they are doing could be automatised, can't they?

At least we don't come up with this kind of crap!

OMG ... its coming ... the future we all have dreaded where in perfectly flat caribbean beaches underwater mines are growing like flowers

Get well, Tom! We urgently need you back.

thanx it is strange, they keep saying they have this synthetic spider silk but there is absolutely no mention of the actual properties of the thing...for a few years now... And I remember we have tested some, way back and it was really bad.

Java is hot again(?) - gotta dig up my old lecture notes.

It actually does make a very weird sound...

I remember that ESA was looking into similar things for the Vulcain 2/2+ NE upgrade together with Volvo and other companies. Does anybody know about the status of that program (google does not ;-))?

Instead of round silk threads this spider produces flat ribbons 40-80 nm in thickness. Still the material is as strong as Kevlar and much more elastic.

"Could you do this? Could a spinning human slow down the Earth? Theoretically, yes." Let's all put our ice skates on and spin to enjoy a longer daytime !

Actually the length of a day fluctuates naturally. Some effects are periodic (e.g. due to seasons) while others accumulate to a general lengthening of the day (like the influence of tides): http://en.wikipedia.org/wiki/Fluctuations_in_the_length_of_day

Is it not more efficient to just all start running eastward? We could have a new "Jump Day" frenzy :)

Not exactly space related but quite interesting how so much of the internet remains unseen.
