Another Leak Delays Final Discovery Launch 104

vsolepr writes "Today's scheduled launch was scrubbed because of a gaseous hydrogen leak near the spacecraft's external tank. This is the fourth time in the past week that Discovery's launch was delayed due to various leaks and electrical issues. NASA now is aiming for a launch date no earlier than Nov. 30."

Either way the current camera isn't a still cam but a motion camera and has outputs and software for the formats and software tools that are used in digital film editing. And besides, complaining that there's no free software for a camera setup that's around $30,000 for a basic moderately featured setup is kinda silly.
I have no doubt the new still capable cameras will support writing standard .jpg, .png, .raw, etc. onto CF cards when running in still mode.

They already provide freely downloadable tools for processing the encoded RAW footage into more common formats (http://www.red.com/support REDCine works on Intel Mac or Windows) and can export to TIFF, JPEG, and OpenEXR (and possibly more, those were just the ones I saw mentioned in the latest release notes). They're also putting out a SDK for the format so it can be integrated into more software. It's not exactly locked down.

Well, they haven't announced anything about storage for the new systems other than a CF adapter for the lower-res units so I can't judge it yet. The Red One however's been out for awhile and has a couple of storage systems. They've got a CF adapter built in with 8GB and soon 16GB high speed cards available. The 8GB cards provide about 4-5 minutes at 4k which is about the same recording time as a 400' film canister (though much, much smaller obviously). Unlike film you can shoot a scene, swap cards and walk that card over to your on-set laptop and dump the footage onto it and a couple of external drives for backup and start editing together a rough cut while the next scene's being shot and then go reuse the card for another shot.
They also offer a hard drive option that uses a pair of 160GB 2.5" SATA drives in RAID-0 and can record 3 hours of footage at 4k (4096x2304).
Compact storage is pretty advanced these days, and RED has a very effective codec that wavelet compresses the RAW footage instead of the processed RGB data. The current camera has 2 encoding modes that work out to approximately 28 or 36 MB/sec at 4k. The top end of the new models is about 35x the resolution of current camera though so even accounting for codec efficiencies they're still going to need quite a bit of bandwidth to actually record that much video data.
Then again given the size of this unit, especialyl once you add lenses, it's pretty much going to be tripod or dolly mounted for any motion shots, not a big deal to have a storage pack on the trolley built into a carrying case. A couple hundred terabytes of RAID configured for speed and hooked up via cable wouldn't be out of line for a setup like that.

Skin Stem Cells Used to Mend Spines of Rats 128

The Toronto Star reports researchers have used adult skin stem cells to heal spinal cord injuries in rats. "Injured rats injected with skin-derived stem cells regained mobility and had better walking co-ordination, according to the study published yesterday in the Journal of Neuroscience. The skin-derived stem cells, injected directly into the injured rats' spinal cords, were able to survive in their new location and set off a flurry of activity, helping to heal the cavity in the cord."
