is a brilliant bioinformatics hacker at UC Berkeley (and also an active happy mutant
in our BB community). A few years ago, I wrote
about Ian's efforts to apply Noam Chomsky's theories about language to the firehose of genetic data spewing from the multitude of DNA sequencing efforts going on these days. Ian just emailed me about his latest research in the mind-blowing area of "paleogenetics." He writes:
Thought you might be interested to know that we & our collaborators recently put together a DNA sequence for the earliest mammal genome, 75 million years old.
Sure, it's full of holes, but it's the first time anyone's done it on this scale!
This whole field, known as "paleogenetics", is really taking off. On the experimental side, you might have heard about the recent sequencing of the Neanderthal and the woolly mammoth.
The cool thing is that you can get a lot of information about ancestral genomes just by crunching probabilities -- even if you don't have any fossils, or mosquitos-trapped-in-amber, or time machines, or whatever.
The even cooler thing (to my bioinformatics-geek mind) is that the algorithms used for this are almost exactly the same ones that linguists use to reconstruct ancient languages, like "Indo-European" or "Gondwanese".
It's only a matter of time before we can actually synthesize these paleogenetic reconstructions. A very short time, according to the Carlson Curves (the Moore's Law of DNA synthesis). Which, of course, has its issues (I am currently trying to reconstruct viruses... no plans to actually synthesize them, I hasten to add...)
Still... I wonder what 75Myr-old mammal meat would taste like? What would be the medicinal properties of ancient herbs? How big were ancient octopi, or spiders? How many genes were in the first bacteria? How long was the first self-replicating RNA sequence?
What would you reconstruct, if you could? Dodo, trilobyte, velociraptor?
I’ve mentioned it online before, but here we go: Two years ago, my wife and I decided to leave our rented home behind and move into a 40-foot RV. We spend our spring and summer in Alberta, Canada where she has a job for six months of the year working as an addictions counselor. The […]
Androkavo tests some of the cheap eBay solder against the brand-name stuff; it gets there in the end, but it’s surely not the advertized 60/40 alloy and needs to be close to 400° before it behaves itself.
MIT Tech Review's Antonio Regalado rounds up the year's stupidest, worst moments in tech, from the guy who created his own CRISPR-based gene therapy to beef up his muscles and injected it to Donald Trump's Twitter feed to the FCC's Net Neutrality catastrophe. Of course, Juicero rates a mention.
The Nintendo Switch is king when it comes to gaming on the go, but it’s tough to lose yourself in Zelda: Breath of the Wild or Skyrim if your battery dies out. That’s where this Nintendo Switch Battery Charger Case comes into play. Built exclusively for Nintendo Switch, this pack allows for uninterrupted charging while you play, […]
Creative designers play a pivotal role in engaging target audiences and customers, and while companies are eager to bring more of these professionals on board, you’ll have a hard time getting your foot in the door if you’re not using the industry’s best tools. From Adobe to Maya, the eduCBA Design & Multimedia Lifetime Subscription Bundle […]
As more companies aim to reel in costs and boost productivity, project managers are becoming an essential part of many operations, and they’re paid handsomely for their expertise. But, while demand is high, you’ll have a hard time getting your foot in the door if you’re not toting the right certifications. The Official Lean Six Sigma […]
