Science and the movies (Bond’s Spectre and The Martian)

There’s some nanotechnology in the new James Bond movie, Spectre, according to Johnny Brayson in his Nov. 5, 2015 (?) article for Bustle (Note: A link has been removed),

James Bond has always been known for his gadgets, and although Daniel Craig’s version of the character has been considerably less doohickey-heavy than past iterations, he’s still managed to make use of a few over the years, from his in-car defibrillator in Casino Royale to his biometric-coded gun in Skyfall. But Spectre, the newest Bond film, changes up the formula and brings more gadgets than fans have seen in years. There are returning favorites like a tricked out Aston Martin and an exploding watch, but there’s also a new twist on an old gadget that allows Bond to be tracked by his bosses, an injected microchip that records his every move. …

To Bond fans, though, the technology isn’t totally new. In Casino Royale, Bond is injected with a microchip that tracks his location and monitors his vital signs. However, when he’s captured by the bad guys, the device is cut out of his arm, rendering it useless. MI6 seems to have learned their lesson in Spectre, because this time around Bond is injected with Smart Blood, consisting of nanotechnology that does the same thing while flowing microscopically through his veins. As for whether it could really happen, the answer is not yet, but someday it could be.

Brayson provides an introduction to some of the exciting developments taking place scientifically in an intriguing way by relating those developments to a James Bond movie. Unfortunately, some of  his details  are wrong. For example, he is describing a single microchip introduced subcutaneously (under the skin) synonymously with ‘smart blood’ which would be many, many microchips prowling your bloodstream.

So, enjoy the article but exercise some caution. For example, this part in his article is mostly right (Note: Links have been removed),

However, there does actually exist nanotechnology that has been safely inserted into a human body — just not for the purposes of tracking.  Some “nanobots”, microscopic robots, have been used within the human eye to deliver drugs directly to the area that needs them [emphasis mine], and the idea is that one day similar nanobots will be able to be injected into one’s bloodstream to administer medication or even perform surgery. Some scientists even believe that a swarm of nanobots in the bloodstream could eventually make humans immune to disease, as the bots would simply destroy or fix any issues as soon as they arrive.

According to a Jan. 30, 2015 article by Jacopo Prisco for CNN, scientists at ETH Zurich were planning to start human clinical trials to test ‘micro or nanobots’ in the human eye. I cannot find any additional information about the proposed trials. Similarly, Israeli researcher Ido Bachelet announced a clinical trial of DNA nanobots on one patient to cure their leukemia (my Jan. 7, 2015 posting). An unsuccessful attempt to get updated information can found in a May 2015 Reddit Futurology posting.

The Martian

That film has been doing very well and, for the most part, seems to have gotten kudos for its science. However for those who like to dig down for more iinformation, Jeffrey Kluger’s Sept. 30, 2015 article for Time magazine expresses some reservations about the science while enthusing over its quality as a film,

… Go see The Martian. But still: Don’t expect all of the science to be what it should be. The hard part about good science fiction has always been the fiction part. How many liberties can you take and how big should they be before you lose credibility? In the case of The Martian, the answer is mixed.

The story’s least honest device is also its most important one: the massive windstorm that sweeps astronaut Mark Watney (Matt Damon) away, causing his crew mates to abandon him on the planet, assuming he has been killed. That sets the entire castaway tale into motion, but on a false note, because while Mars does have winds, its atmosphere is barely 1% of the density of Earth’s, meaning it could never whip up anything like the fury it does in the story.

“I needed a way to force the astronauts off the planet, so I allowed myself some leeway,” Weir conceded in a statement accompanying the movie’s release. …

It was exceedingly cool actually, and for that reason Weir’s liberty could almost be forgiven, but then the story tries to have it both ways with the same bit of science. When a pressure leak causes an entire pod on Watney’s habitat to blow up, he patches a yawning opening in what’s left of the dwelling with plastic tarp and duct tape. That might actually be enough to do the job in the tenuous atmosphere that does exist on Mars. But in the violent one Weir invents for his story, the fix wouldn’t last a day.

Surgical nanobots to be tested in humans in 2015?

Thanks to James Lewis at the Foresight Institute’s* blog and his Jan. 6, 2015 posting about an an announcement of human clinical trials for surgical nanobots (Note: Links have been removed),

… as structural DNA nanotechnology rapidly expanded the repertoire of atomically precise nanostructures that can be fabricated, it became possible to fabricate functional DNA nanostructures incorporating logic gates to deliver and release molecular cargo for medical applications, as we reported a couple years ago (DNA nanotechnology-based nanorobot delivers cell suicide message to cancer cells). More recently, DNA nanorobots have been coated with lipid to survive immune attack inside the body.

Lewis then notes this (Note: A link has been removed),

 … “Ido Bachelet announces 2015 human trial of DNA nanobots to fight cancer and soon to repair spinal cords“:

At the British Friends of Bar-Ilan University’s event in Otto Uomo October 2014 Professor Ido Bachelet announced the beginning of the human treatment with nanomedicine. He indicates DNA nanobots can currently identify cells in humans with 12 different types of cancer tumors.

A human patient with late stage leukemia will be given DNA nanobot treatment. Without the DNA nanobot treatment the patient would be expected to die in the summer of 2015. Based upon animal trials they expect to remove the cancer within one month.

The information was excerpted from Brian Wang’s Dec. 27, 2014 post on his Nextbigfuture blog,

One Trillion 50 nanometer nanobots in a syringe will be injected into people to perform cellular surgery.

The DNA nanobots have been tuned to not cause an immune response. They have been adjusted for different kinds of medical procedures. Procedures can be quick or ones that last many days.

Using DNA origami and molecular programming, they are reality. These nanobots can seek and kill cancer cells, mimic social insect behaviors, carry out logical operators like a computer in a living animal, and they can be controlled from an Xbox. Ido Bachelet from the bio-design lab at Bar Ilan University explains this technology and how it will change medicine in the near future.

I advise reading both Wang’s and Lewis’ posts in their entirety. To give you a sense of how their posts differ (Lewis is more technical), I solicited information from the websites hosting their blog postings.

Here’s more about Wang from the About page on the Nextbigfuture blog,

Brian L. Wang, M.B.A. is a long time futurist. A lecturer at the Singularity University and Nextbigfuture.com author. He worked on the most recent ten year plan for the Institute for the Future and at a two day Institute for the Future workshop with Universities and City planners in Hong Kong (advising the city of Hong Kong on their future plans). He had a TEDx lecture on Energy. Brian is available as a speaker for corporations and organizations that value accurate and detailed insight into the development of technology global trends.

Lewis provides a contrast (from the About page listing Lewis on the Foresight Institute website),

Jim received a B.A. in chemistry from the University of Pennsylvania in 1967, an M.A. in chemistry from Harvard University in 1968, and a Ph.D. in chemistry, from Harvard University in 1972. After doing postdoctoral research at the Swiss Institute for Experimental Cancer Research, Lausanne, Switzerland, from 1971-1973, Jim did research in the molecular biology of tumor viruses at Cold Spring Harbor Laboratory, Cold Spring Harbor, NY, from 1973-1980, first as a postdoctoral researcher, and then as a Staff Investigator and Senior Staff Investigator. He continued his research as an Associate Member, Basic Sciences Division, Fred Hutchinson Cancer Research Center, Seattle, WA, from 1980-1988, and then joined the Bristol-Myers Squibb Pharmaceutical Research Institute in Seattle, WA, as a Senior Research Investigator from 1988-1996. Since 1996 he has been working as a consultant on nanotechnology.

Getting back to Bachelet, his team’s work, a precursor for this latest initiative, has been featured here before in an April 11, 2014 post,

This latest cockroach item, which concerns new therapeutic approaches, comes from an April 8, 2014 article by Sarah Spickernell for New Scientist (Note: A link has been removed),

It’s a computer – inside a cockroach. Nano-sized entities made of DNA that are able to perform the same kind of logic operations as a silicon-based computer have been introduced into a living animal.

Ido Bachelet can be seen in this February 2014 video describing the proposed surgical nanobots,

Computerized cockroaches as precursors to new healing techniques

The last time I wrote about cockroaches was in a June 26, 2013 posting about cyborg cockroaches and neuroscience. This latest cockroach item, which concerns new therapeutic approaches, comes from an April 8, 2014 article by Sarah Spickernell for New Scientist (Note: A link has been removed),

It’s a computer – inside a cockroach. Nano-sized entities made of DNA that are able to perform the same kind of logic operations as a silicon-based computer have been introduced into a living animal.

The DNA computers – known as origami robots because they work by folding and unfolding strands of DNA – travel around the insect’s body and interact with each other, as well as the insect’s cells. When they uncurl, they can dispense drugs carried in their folds.

“DNA nanorobots could potentially carry out complex programs that could one day be used to diagnose or treat diseases with unprecedented sophistication,” says Daniel Levner, a bioengineer at the Wyss Institute at Harvard University.

Levner and his colleagues at Bar Ilan University in Ramat-Gan, Israel, made the nanobots by exploiting the binding properties of DNA. When it meets a certain kind of protein, DNA unravels into two complementary strands. By creating particular sequences, the strands can be made to unravel on contact with specific molecules – say, those on a diseased cell. When the molecule unravels, out drops the package wrapped inside.

Spickernell’s description of the researchers’ plan to increase the amount of computing power in a cockroach to the equivalent of an eight-bit computer seems eye-opening until you read about their plans for preliminary human clinical trials using the same technique for mammals as they have in insects.
