Robot Medic: How Cool is This?

DARPA announced that a robot medic will be ready to deploy in 2009. Science fiction come to life!!!
One of the first announcements at this year's three-day DARPATech conference is going to be hard to top: the first portable, self-contained surgical robot will be deployed in the next two years. Brett Giroir, director of the research agency's Defense Sciences Office also announced that the system, called Trauma Pod, has successfully "treated" a mannequin during a test, with no complications.

A single human will operate the robot remotely during surgery, but Trauma Pod will be able to perform a number of functions, such as fluid administration and surgical assistance, autonomously. The goal is to stabilize injured soldiers as quickly as possible, and previous Trauma Pod designs have included related systems that evacuate the patient. Giroir said that a prototype will be delivered to troops within two years.
In the immortal words of Keanu Reeves as Neo: "Whoooaa!"

Children Without Sex, Sex Without Children

Well, you can already have the latter for the most part, if you exercise some due care. What is the fun in the first proposition though?

The Daily Mail has a feature story which posits a future where people delay having children and then using lab procedures to fertilize an egg. Sex would be for pleasure only not for procreation.
One might think this Huxleyesque vision of a Brave New World just a few years from now sounds a little fantastical. Yet it is the prediction of one of the world’s most eminent scientists, Carl Djerassi.

Professor Djerassi is the man who invented the Pill, the first oral contraceptive, which triggered the sexual revolution of the 1960s, and which many would argue changed the face of society and sexual morality for ever — and not necessarily for the better.

The Pill gave us sex without children. Now Djerassi has turned that concept on its head. He believes the developed world is heading towards its next cultural revolution — children without sex.

"It is my own prediction that within the next 30 to 50 years in the Western world, many women, when young, will bank their eggs or ovarian tissue, have them frozen, and use them when they feel the time is right for them to have a child," he says. "It will become commonplace.

"The world has changed. The days are past in which women in countries like Britain have economic dependence on their husbands and take care of the children.

"The days are past when women looked after children and nothing else. Women have careers now. They are better educated, more affluent and healthier on the whole, and many are now living into their 80s.

"They postpone having children until later and then they forget — or remember too late. Soon there will be nothing to stop a woman freezing her eggs when they are at their healthiest and then using them later on in life."

Less than a decade ago, such a scenario would have seemed impossible. But even now, there are indications that Professor Djerassi’s prediction will come true. A handful of babies have already been born using frozen eggs.
There are some real ethical and moral issues invovled, leaving aside issue of religious morality. The article at least raises those concerns.
Widespread freezing of eggs, if Djerassi’s prediction is correct, is bound to prove controversial. Is it ethical for women to have children in their 60s? How will the child born using such a procedure be affected both emotionally and physically? Even today we do not know what the long-term consequences of IVF will be on those children it has helped to create.

And then, of course, there is the question of women choosing to defrost and fertilise eggs without bothering to find a partner to help raise the child. Do we really want science to create a generation of ageing mothers who’ve chosen to corrupt nature for the sake of their careers by having children late in life — with or without a man?

Djerassi is dogmatic in his rejection of these moral and social concerns. Controversially, he believes advances in egg freezing techniques would be greatly beneficial to the human race. "There are so many unwanted children in the world," he says.

"This would be a way of helping to reduce the number of unwanted children. Every child born to a woman who has taken a conscious decision to have a child at that time would be wanted and loved and properly cared for.

"Is there not something to be said for wisdom, affection and maturity? Why shouldn’t a woman have a child when she is older if the science is there to help her? Nowadays it is not thought peculiar if a man in his 50s or 60s has a child. So should it be different for a woman?"
I need to ruminate on this a little more, but my gut reaction is that while doing this might be a reasonable exception to the rule, it should remain just that, the exception.

Paramedic/Police

The Washington Post has an interesting story on the development and deployment of "tactical medicine" in some police units.
Teresa Hughes is sure about what saved her life on the winter night in 2004 when her boyfriend shot her in the face: It was the emergency medical care she received from the specially trained team of Maryland State Police officers who broke into her house to rescue her. Falling in and out of consciousness, she heard one trooper say, "Oh my, we're going to get you some help, sweetie, we're going to get you help." He and his colleagues stabilized her and got her to a waiting helicopter that whisked her to the shock trauma center in Baltimore.

The treatment Hughes received that night on the floor of the couple's Taneytown, Md., home is on the front line of emergency medicine and freshly under the spotlight because of the shootings at Virginia Tech. Under traditional emergency medical services (EMS) protocol, medical first responders wait outside a crime scene, or "hot zone," until it is deemed safe by the police. That can take precious minutes or even hours -- and can mean the difference between life and death. But in Hughes's case, the SWAT team included troopers who had been trained as paramedics and were able to give her immediate care, despite fears that her boyfriend might be barricaded inside the house.

Maryland State Police (MSP), along with police in Fairfax and Montgomery counties, the U.S. Park Police and some divisions of the Virginia State Police, are among the agencies that have embraced so-called tactical medicine, embedding paramedics and even physicians into special operations teams in the hope of saving lives, not only in the kind of domestic attack that Hughes suffered but in mass killings and school shootings like last week's rampage at Virginia Tech.
The training is based in large part upon military battlefield training. Even with rapid response helicopter transport, the difference between a live soldier and a dead one may be the team's medic. The same difference also applies to shooting victims and other crime victims.
