some ideas for movie Fridays A "must" see on my opinion (never heard about it in the past!) : Primer Sounds ideal: "Primer is a 2004 American science fiction film about the accidental discovery of time travel. The film was written, directed and produced by Shane Carruth, a mathematician and a former engineer, and was completed on a budget of $7,000.[1] Primer is of note for its extremely low budget, experimental plot structure and complex technical dialogue, which Carruth chose not to 'dumb down' for the sake of his audience. One reviewer said that "anybody who claims [to] fully understand what's going on in Primer after seeing it just once is either a savant or a liar."[2] The film collected the Grand Jury Prize at Sundance in 2004 before securing a limited release in US cinemas, and has since gained a cult following."

I watched it a while ago during my studies in Belgium... The plot is quite well summarized on this diagram: http://xkcd.com/657/large/ According to the text above I'm either savant or a liar (you choose). But I watched the movie under significant exposure to Belgian beer, so this may have helped...

apparently first time that somebody filmed a meteorite falling after the luminous phase .... impressive pics

I've seen someone suggest it could have been a rock that ended up inside the parachute bag when it was folded, and then fell when the parachute was deployed.

Ultrathin films of highly monodispersed luminescent Si nanoparticles are directly integrated on polycrystalline Si solar cells. The authors monitor the open-circuit voltage and the short circuit current. The results demonstrate that films of 1 nm blue lu

A UK-based start-up is developing printable, thin-film plastic solar cells aimed at providing affordable electricity to individual dwellings that have no grid connection, such as those in rural Africa

any clue how? "With the peel-and-stick process, we integrated hydrogenated amorphous silicon (a-Si:H) TFSCs on paper, plastics, cell phone and building windows while maintaining the original 7.5% efficiency. The new peel-and-stick process enables further reduction of the cost and weight for TFSCs and endows TFSCs with flexibility and attachability for broader application areas. We believe that the peel-and-stick process can be applied to thin film electronics as well"

"Applications for the film extend beyond getting rid of wrinkles, though. It can safely deliver medications for 24 hours at a time as well as protect the user's skin, particularly over wounds. Additionally, the XLP material can reduce moisture loss. "

Researchers at the University of Toronto in Canada and KAUST in Saudi Arabia have made a solar cell out of colloidal quantum dot (CQD) films that has a record-breaking efficiency of 7%. This is almost 40% more efficient than the best previous devices based on CQDs.

Thin-film solar cells could be made far more efficient with the addition of bundles of carbon nanotubes.

Lionel could you have a closer look at this one?

Probably related to the former ACT study on asteroid spin-up and the YORP effect.

You can yell, "Beam me up, Scotty!" all you want, the only thing that will happen is you'll elicit a bunch of bemused stares from passersby wondering if you've bonked your head recently. The sad fact is human teleportation devices don't yet exist in 2013, and even if they did, the tremendous lag would make it extraordinarily impractical.

A startup with a secret recipe for printing cheap solar cells on aluminum foil debuted today, in what could end up a milestone.

fantastic!!!

An educational movie on biomimetics. (german)

I am quite amazed that they apparently still use the capsules to return the pictures??? Hard to believe .... "Kobalt spacecraft reportedly carry canisters to return film to Earth during the satellite's mission, which will last at least several months."
