I performed the first Hd surgery in 2000 befoore we did this 4K project last month. The best surgical cameras we use tp perform the operation through a scope are only HD ---BUT there is no 1/3 inch HD surgical camera chip they are all upscaled 1/2 HD or worse. he red was an order of magnitude beyond anything I used before. The monitors referenced above are mainly used for radiology and microscopes never for endoscopic surgery
No -- we used the sony projector (SRX-220) but due to audience size we needed 3 of them, them add 3D and stack them in double. Add couple of hundred K for real D 3D lenses and for 4K servers. Sony was the partner who set up equipment for us thank goodness.
more of an issue than ritalin are eugaroics such as provigil. Already given out to pilots by the airforce it is being used with increasing frequency by students for exams, shift workers in factories and doctors on long duty schedules. I know of prominant physician researchers and academics who have iused it in situations of sleep deprivation. It allows one to function for extended periods without sleep without losing performance, it keeps mental acuity and raction times and recall stable (newer DARPA funded versions actually increase performance) and has no rebound effects.
I appreciate/. linking to my post on this topic- I wanted to a share some further details of the drugs. I predict the potential for use/abuse of these agents to be unprecedented.
The primary agents to hit the streets are eugaroics. They are a class of novel stimulants that produce long-lasting mental arousal. They are unique in producing hypervigilence and alertness without peripheral effects or addidition of usual stimulants. Strangely, they have minimal effect on sleep structure, and do not cause rebound hypersomnolence (crashing).
You might also be interested in Ampakines are similar but also cause memory enhancement (just a bit of abuse potential there). One of these - a drug code-named CX717 from Cortex - reportedly enabled sleep deprived rhesus monkeys to outperform rested normal monkeys on memory tasks.

the biggest issue here is how far would you go to enhance your body's performance if risks were minimal? Would you take a drug, implant a bionic retina? or replace your limbs with bionic ones. Discussions I have had with those on the international olympic committee and DARPA indicate many many people will go the route of biomodification. A discussion of this concept is here:

Surgical robotics was initially conceived by DARPA as remote battlefront or space surgical robots and this technology is now widely available in the DaVinci surgical robots. I had had the fortune to have used these in the OR and to have spoken to the people at DARPA about the TraumaPod. Here is a link to my post on the traumapod that includes 3 videos from DARPA. These show their videogame-like concept animation and 2 work in progress videos of the systems.

From the Who Needs VC Department comes an amazing development from Cornell. The Fab @ Home poject has developed a desktop fabricator that will sell for under $2500. For those of you not familiar with these devices check out the video- they are a marvel to watch! And it's opensource!!
The standard version of their Freeform fabricator - or "fabber" - is about the size of a microwave oven and can be assembled for around $2400 (£1200). It can generate 3D objects from plastic and various other materials. Full documentation on how to build and operate the machine, along with all the software required, are available on the Fab@Home website, and all designs, documents and software have been released for free.
details and videos avalable at: http://docinthemachine.com/2007/01/10/fabricator/
http://www.docinthemachine.com/ reported in January on the development of a product called Electriplast that is a resin based electrically conductive plastic- and that is commercially available. I believe it has potential in the medical device market as well as consumer electronics.
You can read more about the product at : http://docinthemachine.com/2007/01/08/electriplast /
"Electriplast is a highly conductive recipe that can be molded into virtually any shape or dimension associated with the range of plastics, rubbers and polymers. CES chose this technology with a 2007 Innovation honoree for enabling technologies. Now it's just a matter of convincing manufacturers to look at the small medical tool market and not focus on its current #1 use- next generation cell-phone antenna."
There are so many comments on the nature of peer review. Let's call a spade a spade. From the lazy reviewer (jeez my review has 12 major flaws the oter reviewer corrected 3 misspelled words) to the one who knows nothing about the topic to the "trickle down review" where the chair gives it to a fellow to do -- here are what I see as the basic flaw of the peer review system!

There is so much argument about whether the civilian pay-off from military research makes sense. Here is a bit of research on the medical end and some reasons why private industry does not take the risks DARPA does.

The progressive killing off of traditional print publishing by e-publishing is true and here to stay in all fields. Hre is a review of how strong this trend is in medical e-publishing where free open source e-text is replacing traditional medical journals. The same is happening for fiction.

The concept of a temperature sensitive plastic is interesting but I have seen in clinical trials substances even more strange and amazing. These are substances with "reverse thermal gelation properties". In general, stuff is liquid when hot and when colled becomes solid (really just about any stuff in the world). Well-- substabnces have been created with reverse properties - that is they are liquids when coooler and SOLIDIFY when heated! THe first medical use was a spray on scar tissue prevention substance. It seals cut raw edges inside the body. Sprays on as a liquid (ie easy to apply and fills the nooks and crannies) then it solidifies as it warms and forms a shell like protective coating (not chocolate however) while the body heals underneath- then dissolves. The substance being tested is called Poloxamer 407
