This photo, one of the winners of the Engineering and Physical Sciences Research Council’s (EPSRC) annual photography contest, shows a rotating viscoelastic jet. Rotating liquid jets are common to many manufacturing processes, and their sometimes-wild appearance comes from a balance of gravitational forces and centrifugal force against surface tension. But because this fluid contains a small amount of polymer additive, surface tension has the additional aid of some elasticity to help hold the jet together and keep the globules and ligaments you see from flying off. As centrifugal forces fling the fluid outward, it stretches the polymer chains within the fluid, and they pull back against that tension like a stretched rubber band. To see some of the other contest winners–including other fluids entries!–check out the Guardian’s run-down. (Image credit and submission: O. Matar et al., ICL press release)
During preparations for “The Sound is Watching You” we’ve spent a lot of time figuring out projector throw ratios and sizing staging areas. We have blisters from frequent tape measure use, and we’re a little concerned that we’re getting grid views burned into our retinas. But it’s all coming together very nicely, and we’re getting more excited each day to be able to share “The Sound is Watching You” with all of you!

Yesterday we announced that our installation “The Sound is Watching You” would be presented by NAISA as part of their 2013 Art’s Birthday Celebrations. We're very excited about this opportunity and judging from the response we’ve received so far, it seems like a number of you are too! We hope that we’ll see you all at the show when it opens later this week. In addition to making announcements, yesterday was also spent getting to know the space. There’s a lot of stuff that has to be done before we open the doors, not the least of which is getting to know the space…

SubZeroArts is thrilled to announce “The Sound is Watching You” as part of New Adventures in Sound Arts’ annual Art’s Birthday Celebration for 2013!
SubZeroArts’ installation “The Sound is Watching You” will be displayed as part of New Adventures in Sound Arts’ annual Art’s Birthday Celebration at Artscape Wychwood Barns in Toronto, Ontario from January 17 to February 18, 2013. “The Sound is Watching You” is a surround-sound and visual experience that responds to audience participation, where audience movement is transformed into a symphony of constantly morphing and re-generating music and light. In keeping with SubZeroArts’ ideal of audience interaction, “The Sound is Watching You” is a multimedia experience that’s fun and engaging for audience members of all ages.

this is really late but, just some almost decent shots at nuit blanche before my camera died.

Beautiful!
New tool enables surgery in space.
Researchers at Carnegie Mellon University have created a tool which creates an airtight seal over a wound, enabling surgery in space. Traditional surgery in space would contaminate the cabin with blood, but the ‘Aqueous Immersion Surgical System’ is able to cover the wound and contain or even reuse blood for later use.
The transparent box is pumped full of a sterile saline solution, which can contain blood from escaping by adjusting the pressure. That pressure could also be adjusted to pump blood out to be stored for later use - useful in space where there is no bloodbank.
The device will next be tested aboard NASA’s zero gravity C-9 aircraft, and it is hoped it may be used aboard the ISS or on longer space mission in the future, such as missions to Mars.
At last there is new hope for all those poor Red Shirts...
Quite beautiful.
The Rayleigh-Taylor instability can form at the interface between two liquids of different density under the influence of gravity, but a similar instability can occur in the absence of gravity. The image sequence above shows the Richtmyer-Meshkov instability, which occurs between two liquids of differing densities (regardless of their orientation) when impulsively accelerated. In this case, the experiment was conducted in a drop tower to simulate microgravity with the apparatus dropped on a spring to provide the impulse. As the instability grows, asymmetries appear. Nonlinear dynamics will amplify these distortions, eventually leading to turbulent breakdown. (Photo credit: C. Niederhaus/NASA Glenn, J. Jacobs/University of Arizona)

A Planetary Nebula Gallery
This gallery shows four planetary nebulas from the first systematic survey of such objects in the solar neighborhood made with NASA’s Chandra X-ray Observatory. The planetary nebulas shown here are NGC 6543, also known as the Cat’s Eye, NGC 7662, NGC 7009 and NGC 6826. In each case, X-ray emission from Chandra is colored purple and optical emission from the Hubble Space Telescope is colored red, green and blue.
I guess today is pretty pictures day…
