Why modeling & simulation, imaging and robotics• Healthcare is the only industry without a computer representation of its “product”
•A robot is not a machine . . .it is an information system with arms . . .
• A CT scanner is not an imaging system it is an information system with eyes . . .
thus
• An operating room is an information system with . . .

“Remote Pilots”
A last bastion of guts-and-glory aviation is falling, as the U.S. Air Force prepares to unveil a new breed of unmanned aircraft pilots. Known as “remote pilots”, they’ll wear wings. They’ll fly aircraft. But chances are many will never climb into a cockpit. . Senior leaders have yet to approve the new Undergraduate Remote Pilot Training (URT), but Air Force officers familiar with the project expect approval by the end of the year. Instead of sticking reluctant manned aviators behind a console, the Air Force will groom remote pilots from the start to fly what the service now calls unmanned aerial systems

urothelial and smooth muscle cells that are capable of regeneration are isolated.
The isolated cells are cultured separately until there are a sufficient quantity.
The cultured cells are properly seeded onto a biodegradable scaffold shaped like a bladder.
Quality assurance that the cells attach and grow properly throughout the scaffold. After about 8 weeks, the neo-bladder construct is returned to the surgeon for implantation.
The neo-bladder construct is implanted by the surgeon using standard surgical techniques.
The body uses the neo-bladder construct to regenerate and integrate new tissue, restoring the bladder’s functionality.
The biodegradable scaffold dissolves and is eliminated from the body, leaving a functioning bladder made only of the patient’s own newly regenerated tissue.
A surgeon takes a small, full-thickness biopsy from the patient’s bladder.

South Korean team demonstrates cloning efficiency for humans similar to pigs, cattle | Thersa Tamkins
After outlandish claims, a few media circuses, and some near misses by legitimate researchers, a team of South Korean researchers reports the production of cloned human embryos. The findings, were released Wednesday (Science, DOI:10.1126 /science.1094515, February 12, 2004).Wook Suk Hwang and Shin Yong Moon of Seoul National University used somatic cell nuclear transfer to produce 30 human blastocysts and a single embryonic stem cell line; SCNT-hES-1. Using 242 oocytes and cumulus cells from 16 unpaid donors, the group achieved a cloning efficiency of 19 to 29%, on par with that seen in cattle (25%) and pigs (26%).
Human embryos cloned
Chinese Cloning Control RequiredTuesday 16 April, 2002, 10:41 GMT 11:41 UK
Strict ethical guidelines are needed in China to calm public fears about new cell technologies such as cloning, the country's leading scientist said. Professor Ching-Li Hu, the former deputy director of the World Health Organization, was speaking at the Seventh Human Genome Meeting in Shanghai. His call follows recent reports that Chinese scientists are making fast progress in these research fields. One group in the Central South University in Changsa is said to be producing human embryo clones, while another team from the Sun Yat-sen University of Medical Sciences in Guangzhou is reported to have fused human and rabbit cells to make tissues for research.

Five "designer babies" created for stem cell harvest
Five healthy babies have been born to provide stem cells for siblings with serious non-heritable conditions. This is the first time "savoir siblings" have been created to treat children whose condition is not genetic, says the medical team.The five babies were born after a technique called preimplantation genetic diagnosis (PGD) was used to test embryos for a tissue type match to the ailing siblings, reports the team, led by Anver Kuliev at the Reproductive Genetics Institute in Chicago, US.The aim in these cases was to provide stem cells for transplantation to children who are suffering from leukaemia 'Unlawful and unethical' However, the use of this technology to provide a "designer baby" to treat an ill sibling is highly controversial.A UK couple involved in this

Preimplantation Genetic ScreeningGeneral Science: May 13, 2006
A British woman has become the first in the country to conceive a "designer baby" selected specifically to avoid an inherited cancer,
The woman, who was not identified, used controversial genetic screening technology to ensure she does not pass on to her child the condition retinoblastoma, an hereditary form of eye cancer from which she suffers. Doctors tested embryos created by the woman and her partner using in-vitro fertilisation (IVF) methods for the cancer gene. Only unaffected embryos were implanted in her womb, the newspaper said. It suggested the woman's pregnancy would increase controversy over the procedure -- pre-implantation genetic diagnosis (PGD) -- because critics say it involves destroying otherwise healthy embryos whose conditions are treatable.

Emergence of Novel Color Vision in Mice Engineered to Express Human Cone Photo-pigment
Changes in the genes encoding sensory recptor proteins are an essential step in the evolution of new sensory capacities“new sensory capacities" . In primates, tri-chromatic color vision evolved aftre changes in x chromosome linked photopigment genes. Heterogous mouse females human L pigments showed enhanced long-wavelength sensitivity and chromatic discrimination. An inherent plasticity in the mammalian visual system thus permits emergence

26 July 2007 Womb-on-a-chip may boost IVF successesLinda Geddes Teruo Fujii of the University of Tokyo in Japan and his colleagues are building a microfluidic chip to nurture the first stages of pregnancy. They hope, eventually, to create a fully automated artificial uterus in which egg and sperm are fed in at one end and an early embryo comes out the other, ready for implanting in a real mother. They say using such a device could improve the success rate of IVF."While there have been many advances in the production of in vitro embryos, these embryos are still sub-optimal [compared] to their in vivo counterparts," says Matt Wheeler of the University of Illinois in Urbana-Champaign who is also working on automated IVF systems. One reason for this is that during IVF, eggs or embryos are often moved or washed with culture fluid, causing changes in temperature and pH, he says.To tackle these problems, Fujii's team has created a "lab on a chip" that is 2 millimetres across and 0.5 millimetres high, in which up to 20 eggs can be fertilised and then grown until they are ready for implantation. Endometrial cells, which line real wombs, are also grown in the device, so that the chemicals they produce can reach the embryos help them grow. "We are providing embryos (cont. p28)

Life extension
Life extension consists of attempts to extend human life beyond the natural lifespan. So far none has been proven successful in humans. Several aging mechanisms are known, and anti-aging therapies aim to correct one or more of these: Dr. Leonard Hayflick discovered that mammalian cells divide only a fixed number of times. This "Hayflick limit" was later proven to be caused by telomeres on the ends of chromosomes that shorten with each cell-division. When the telomeres are gone, the DNA can no longer be copied, and cell division ceases. In 2001, experimenters at Geron Corp. lengthened the telomeres of senescent mammalian cells by introducing telomerase to them. They then became youthful cells. Sex and some stem cells regenerate the telomeres by two mechanisms: Telomerase, and ALT (alternative lengthening of telomeres). At least one form of progeria (atypical accelerated aging) is caused by premature telomeric shortening. In 2001, research showed that naturally occurring stem cells must sometimes extend their telomeres, because some stem cells in middle-aged humans had anomalously long telomeres.
