In an astonishing step forward in biomolecular computing, Harvard researchers encoded a 19th century film clip in DNA and stored it inside living bacteria. Later, they sequenced the bacterium's genome and decoded the film. From IEEE Spectrum:
To get a movie into E. coli’s DNA, (neuroscientist Seth) Shipman and his colleagues had to disguise it. They converted the movie’s pixels into DNA’s four-letter code—molecules represented by the letters A,T,G and C—and synthesized that DNA. But instead of generating one long strand of code, they arranged it, along with other genetic elements, into short segments that looked like fragments of viral DNA.
E. coli is naturally programmed by its own DNA to grab errant pieces of viral DNA and store them in its own genome—a way of keeping a chronological record of invaders. So when the researchers introduced the pieces of movie-turned-synthetic DNA—disguised as viral DNA—E. coli’s molecular machinery grabbed them and filed them away.
Google and Mozilla are making changes to their respective web browsers to try and thwart the notoriously corrupt government of Kazakhstan’s efforts to launch a surveillance operation against its own citizens.
In 1994, Jeff Schwartz and Dan Wong fired up the San Francisco FogCam. For 25 years, it kept a constant vigil on the San Francisco State University campus, making the FogCam the longest operating webcam in history. (The first webcam, the Trojan Room coffee pot cam, went online in 1991 and shut down in 2001.) […]
Illegitimate, popular vote losing, and manifestly unfit United States President Donald Trump said on Monday that at a recent dinner with Tim Cook — what, you didn’t think they hung out and shared meals? — the Apple CEO made a “very compelling argument” that Apple may lose its competitive edge to Samsung because of Trump’s […]
Are we done with capsule coffee makers yet? Sure, they’re easy. But they are not so easy on the environment, and it’s debatable whether they actually make a better cup. Luckily, there’s never been a better time to switch back to the good old reliable drip method – especially when drip coffeemakers have quietly been […]
If there’s one thing that stayed consistent through the last decade or so of tech industry turmoil, it’s the love affair between techies and Linux. There’s just a ton you can do with the OS, and its open-source format means you can customize your rig from the ground up. Apparently not content with that level […]
Accidents happen. And when they do, you’re going to want a dash cam for a second pair of eyes. At the minimum, a decent dash cam can save you vast sums of time and money in case of an accident. But a really good dash cam can do a whole lot more. Here are six […]
