The new and the new-old: Computers and Woolly Mammoths

January 16, 2012 1 comment

Today on boydfuturist: Advances in computing (and one genetic bombshell.)

I’ll begin with some technical advances in computing during the last week or so. First, links to an article reporting that computer component maker NEC has demonstrated 1.15Tb/s optical transmission speeds over 10,000km (or about 6,200mi). Although it’s probably too soon to hope for internet upgrades for consumers (and might be for the foreseeable future, given the United States’ abysmal internet infrastructure) I can at least dream of upgrading my 300kb/s eventually. This sort of hi-speed internet capability will be vital for the increasing mounds of data that are being sent and received thanks to mobile phones, embedded movies, video conferencing, video gaming, and other hi-bandwidth applications.

To handle the increasing amounts of data, both locally generated and transmitted over the internet, computers are going to need more memory. I suppose I’m dating myself to say that I remember when memory was measured in megabytes, and that 16GB of RAM seems outrageous to me even as I installed it for less than $100 in my buddy’s computer. But we’re going to need more, and it’s going to have to fit in increasingly smaller spaces as we miniaturize computers down to the nano scale. Fortunately, researchers at IBM have stored a byte of memory in a mere 12 atoms, or about 100 times as dense as current materials. Until we can safely and cheaply cool home computers to near absolute zero this won’t be much use at home, but it shows that there is potential to pack a lot of memory into very tiny spaces.

What sort of applications could use such vast amounts of data? Lots, it turns out. Erin Rapacki argues that we ought to begin scanning the “real” world. By scanning every object in the real world in 3-D, we could give computers a vast data set that allows them to recognize virtually any object that they pick up. It turns out that this sort of project is being crowd sourced, with websites being set up for people to upload 3-D scans using their Xbox Kinect to form one enormous database. I have to wonder if increasing reliance on 3-D printers will speed up this process, since any object that we want to print from a 3-D printer needs to be scanned (or built as a file) in 3-D to begin with. Imagine one day being able to download the “Sears Hardware Collection” file and printing whatever tool it is you need at will.

Vinod Khosla argues that computers will take over many of the jobs in the healthcare field, resulting in staggering amounts of data transmitted across the world in the blink of an eye. Whether or not he’s right, there’s no question that healthcare is becoming more automated, scans are taking up more data, and genomics is coming along right behind to fill up whatever empty HDDs are left. It turns out that devices are being created that allow people to control robots with their mind. Given the amount of data the brain creates, no doubt finely tuned devices that will give the same or better performance as natural limbs and organs will need to transmit and/or receive large amounts of information as well. However, even as technology becomes more omnipresent, people are already asking questions about its impact on our biological brains. Just as we start to wonder how technology impacts our biological brain, however, comes news from MIT that they have succeeded in creating a synthetic version of a biological neuron. While we’re hardly ready to build a brain from scratch, this suggests that doing so is not out of the question.

Finally, some non-computing news that is huge. Biologists are now saying that they have the ability to sequence woolly mammoth DNA, replace the relevant bits in an elephant egg, and implant what will be a woolly mammoth into a female elephant. Scientists have said this before, but haven’t had a complete genome to work with because their samples were damaged.  Difficulty: Woolly mammoths have been extinct for thousands of years. Isn’t this how Jurassic Park started and, if so, can it be long before Paris Hilton is walking around with a mini-T-Rex in her purse?

I, for one, certainly hope not.

Sunday Edition: Abundance, Computing, Animal Communication, and Ethics

Any sufficiently advanced technology is indistinguishable from magic. – Arthur C. Clark, scientist and writer.

With that in mind, let’s talk about magic for a minute. Not so long ago (and in some circles still today) people used to talk about alchemy; turning lead into gold was the usual desire. Without knowledge of elements, atoms, and other basic chemistry, the idea was that one substance could be transmuted into another using the philosopher’s stone which, despite its name, was not always a stone but sometimes an elixir or other substance.

Today, we don’t talk about philosopher’s stones, and rarely talk about turning lead into gold. We could plate lead with gold, of course, but that’s not the same. In theory, one could turn lead into gold by reconfiguring the atoms of lead (82 protons and 82 electrons in six fields, with 126 neutrons in the middle) into atoms of gold (79 protons and 79 electrons in six fields, with 118 neutrons in the middle.) It looks so simple, and indeed we have transmuted lead into gold, but, unfortunately, it take massive amounts of energy to swipe a few basic subatomic particles and turn one element into another.

That notwithstanding, transhumanists hope to convert not just lead into gold, but any element into any other. Like Star Trek’s replicator, scientists hope to use some basic bag of material (it really doesn’t matter what), destroy the material by tearing apart the subatomic particles, and then reassembling them into whatever configuration one wants. Bales of hay could be transmuted into a Ferrari, in theory.  The widespread use of that sort of technology leads to what some transhumanists call abundance; the utter irrelevance of ‘(personal) property’ as such because anything can be turned into anything else. I recently ran across the Foresight Institute’s page on molecular assemblers and I’m fascinated. But, by all accounts, the technology is many years away (but would probably represent the most important invention … ever.)

In the meantime, how is abundance looking? The Huffington Post recently ran an article by Peter Diamandis, who argues that technology has already vastly improved the world as a whole. Global per-capita incomes (inflation adjusted) have tripled, lifespands have doubled, childhood mortality has decreased by 99%. His fascinating article goes on to explain why, despite living in vastly better times (as a world community, not just Americans) we’re still focused on the negative.

To power abundance, of either the molecular assembler or the more recognized variety, we’ll need a lot of computing power. Moore’s Law has predicted, accurately, that the number of transistors on a chip would double every couple of years and, as a corollary, that the processing power would double about every 18 months. Every few years, people predict the end of Moore’s Law, but it’s remained accurate since 1965 (and, more generally, for technology since essentially forever according to Kurzweil.) Researchers from the University of South Whales and Purdue have recently created new wires in silicon a stunning one atom tall by four atoms wide. Such small wires could enable quantum computing in silicon; a stunning feat that would continue Moore’s Law into the foreseeable future. Additionally, it makes nano-scale engineering more feasible.

What could we do with all that computing power? Patrick Tucker of the World Future Society recently offered some thoughts. Artificial Intelligence is already being used to replace workers in China, but even professionals like doctors and lawyers are being helped / replaced by automated robots. Managing all the information being created is vital, so AI is being used to search speeches on TV like one searches the web with Google, and also to sift through human genomes to look for similarities. Google is creating self-driving cars. Researchers in China are identifying the cause of traffic jams based on two years worth of GPS data collected from 33,000 cabs. There will be, in short, need for all the computing power we’re inventing.

I’m going to switch gears for a moment to some random new discoveries. Technology Review reports on new advances in carbon nanotubes that are leading to materials that are more conductive and weigh much less than traditional materials. Meanwhile, technology company Lumus has created a pair of see-through augmented reality glasses that are lightweight and project a HD (720p), 3-D, 87″ screen into the wearer’s field of vision. They’re not the most stylish thing in the world, but who wouldn’t love to throw an 87″ TV into their backpack and set it up in the library? Better yet, let’s put these in a bionic eye. Additionally, scientists are trying to use robots to figure out how language evolves in the natural world, including among animals.

In the realm of ethics, Vinton Cerf argues that internet access is neither a human right nor a civil right in the New York Times opinion pages. This is in response, of course, to the argument that internet access -is- a human right, including a UN Report to that effect. Unsurprisingly, the blogosphere (I’ve wanted to use that word for a while) has lit up with responses on both sides. Here’s one example, from JD Rucker.

Finally, if you’re still feeling down about the world, check out Jason Silva’s videos on techno-optimism. The pattern video at the beginning is particularly good.

Gadgets, Brains, and Healthcare

Only five days in to 2012, and mind-blowing articles are already dropping.

According to Pentagon scientists (reported by and others), Cornell students have created a device that splits beams of light, hiding an event from sight. They’re calling it a time cloak. For around 40 picoseconds (trillionths of a second) the scientists are able to create a gap in the light by using a time-lens to split the light into slower red and faster blue components. This makes anything occurring in the gap invisible. In theory scientists could make the device effective for a few millions of a second, or perhaps even a few thousandths of a second, but a device large enough to erase a whole second would need to be approximately 18,600mi long. Even for someone like me who envisions mechanical implants for humans and perhaps even brain uploading into a computer, this article is fantastic. I’d love to see some confirmations of this technology and a better explanation for how, exactly, it works. Still, it seems it won’t be a very effective Ring of Gyges anytime soon, if at all.

Researchers in Japan, meanwhile, have created super sensitive sensors out of carbon nanotubes. The sensor is flexible enough to be woven into clothing, and can be stretched to three times its normal size. In addition to rehabilitation uses, this sort of sensor seems great for the blossoming world of controllerless video game systems like the Xbox Kinect. Such sensors are also implantable into people receiving organs (biological or otherwise) or could just be used to record biometrics in your everyday clothing.

Finally, Klaus Stadlmann gives a TED Talk about inventing the world’s smallest 3-D printer. It seems to be about the size of a Playstation 2, and can print in incredible detail. I thought the talk was a little dry, but still interesting.

There have been several interesting brain articles in the last few days. Forbes ticks down their top-10 brain articles from 2011, including memory-assisting chips, using magnetism to affect moral judgments, potential treatments for people suffering from Alzheimer’s disease, and thought-controlled apps for your cell phone. Although the brain is still largely mysterious, scientists are making massive amounts of progress on all fronts yearly.

Discover Magazine reports that anesthesia might be the key to better understanding how consciousness works. Apparently it’s not unusual for patients under anesthesia to wake up, then go back under and never remember that they woke up. I’ve talked a bit about the problem of recognizing consciousness before (one essentially has to rely on reports of consciousness, but consciousness itself cannot be directly tested for) and this article does a good job of reiterating the problem. The researchers hope that by putting people under and eliciting subjective reports of consciousness after the fact, they will be better able to pin down just what it is that makes a person conscious. posted an article in December asking Why Aren’t We Smarter Already? The authors suggest that there is an upper-limit to various brain functions, and that while drugs and other things could potentially bring low-scoring individuals up, those already at or near peak performance would see little or no gain from the same drugs. If this is right, then there is reason to doubt that mind-enhancing drugs (say, Adderall) could make the smartest people even smarter. Yet, the article only talks about improving the mind that we have, and not about whether it is possible to create an artificial brain (or introduce artificial implants into a biological brain) that -could- break past these natural barriers. It’s no secret that the body is well, but not optimally, designed, and that the same is true of the brain shouldn’t really be surprising.

TechCrunch offers a predictive list of technologies coming in 2012 in an article penned by tech luminary and SingularityU professor Daniel Kraft. According to Daniel, A.I. will become increasingly helpful in determining diseases, from cheap phone apps that detect cancer with their cameras to A.I. assisted diagnoses in remote villages. 3-D printing will continue to advance, massive increases in patient data will be shared on social network sites like, and videoconferencing technology like Skype will increasingly allow doctors to examine patients without an office visit. All good things.

Last, but not least, a team of scientists at USC have recently mapped an entire human genome in 3-D. They hope to be able to evaluate genomes not just based on their genetic make-up, but also their physical structure. Because genomes take up three dimensions in the body, a 3-D map should be a lot more accurate than the standard model.


GM Food, Human Enhancement, Materials Science, Solar Panels, and Human Genome Sequencing

December 31, 2011 16 comments

Some thoughts on genetically modified foods in the future, courtesy of Sentient Developments.  In the present, however, there seem to be plenty of problems with GM foods as developed by Monsanto,potentially resulting in suicides in India and a recent link to mammalian organ failure.

Ronald Bailey makes the Case For Enhancing People, an excellent article that I might have to post some more commentary on once the holidays have passed and I have a day or two to really think about everything he’s saying.

MIT has a nice summary of materials science advances in the past year, including much more efficient color-emitting technology, vastly more efficient batteries, and invisibility cloaks.

Care2 has a short piece on cheap solar panels; not very powerful, but enough to make a significant difference in the poorest of countries.

Finally, doctors are going to begin routinely screening human genomes in some hospitals to help cross reference (presumably anonymous) patient data in an effort to find commonalities between people with diseases. The information mined from this ought to help create more effective drug treatments, or even allow for the beginnings of customized medicine.

Happy New Year to everyone!
