Watch an octopus disappear into "quicksand" on the sea bottom


The southern sand octopus (Octopus kaurna) whips up some seafloor "quicksand" lined with mucus and burrows into it to rest during the daytime. From New Scientist:

(University of Melbourne researcher Jasper) Montana and his team first caught the octopus in the act of burrowing in 2008 when they were scuba diving at night in Port Philip Bay, south of Melbourne, Australia. When they shone a light on the octopus, the startled animal spread out its arms and repeatedly injected high-powered jets of water into the sediment using its funnel. This caused grains of sand to be temporarily suspended in water, making it like sandy water.

“The sediment became fluid like quicksand,” Montana says. The octopus put its arms into the sand while still pumping out water and eventually dived down into the sediment. The liquefied sand is likely to reduce drag and so allow the animal to burrow more quickly, using less energy, Montana’s team speculates....

They (later) found that the animal used its arms and mantle to push the sand away and form a burrow. It also extended two arms to the surface to create a narrow chimney to breathe through. Finally, it secured the walls of its new home with a layer of mucus that kept the grains of sand together so the entire thing maintained its shape.

What you can learn from the million-dollar tuna

On Saturday, a bluefin tuna was sold at Tokyo's Tsukiji fish market tuna auction for $1.76 million. Which is a little crazy. (Also crazy, the size of the fish in question.) But the amount paid for this specimen of a chronically overfished species doesn't really represent simple supply and demand, explains marine biologist Andrew David Thaler. It shouldn't be read as a measurement of tuna scarcity, he says, but rather as an artifact of culture (and marketing). Read the rest

ZaReason: a computer company with freedom built in

For the past couple of months, I've been playing with a laptop from ZaReason, a small, GNU/Linux-based system builder founded in Oakland, CA (though it has expanded to New Zealand). ZaReason's deal is that they build computers themselves, using components that are guaranteed to have free and open drivers, and pre-install your favorite free/open operating system at the factory. They offer full support for the hardware and the software, and promise that they'll never say, "Sorry, that component just doesn't work right under Linux." So unlike buying a ThinkPad or other commercial laptop and installing a free operating system on it (which can be a bit of a gamble, and will shortly become more of one, see below), ZaReason's machines arrive ready to run. And unlike buying a commercial laptop from a freedom-friendly vendor like Emperor Linux (who'll sometimes warn you that certain features of your hardware aren't supported), ZaReason can promise you that every single capability of every single component in your system will just work.

ZaReason sent me their Alto 3880, "Long battery life, HD graphics, light and lean = everything a laptop should be." I found it to be a very snappy, responsive machine that, as promised, "just worked" out of the box. The machine's styling is pretty generic -- it looks like your basic, silvery OEM laptop, albeit one where they've opted for the top-spec option for the pointing surface, keyboard, etc. It's rather heavier than the machine I carry for daily use, a Lenovo ThinkPad X220, which shaves its ounces by omitting the optical drive and shrinking the screen to 12" (the Alto has a 14" screen).

Lockdown: free/open OS maker pays Microsoft ransom for the right to boot on users' computers

A quiet announcement from the Fedora Linux community signals a titanic shift in the way that the computer market will work from now on, and a major threat to free/open operating systems. Microsoft and several PC vendors have teamed up to ensure that only operating systems bearing Microsoft's cryptographic signature will be able to boot on their hardware, meaning that unless Microsoft has blessed your favorite flavor of GNU/Linux or BSD, you won't be able to just install it on your machine, or boot to it from a USB stick or CD to try it out. There is a work-around for some systems involving a finicky and highly technical override process, but all that means is that installing proprietary software is easy and installing free/open software is hard.

This is a major reversal. For many years now, free/open OSes have been by far the easiest to install on most hardware. For example, I have installed Ubuntu on a variety of machines by just sticking in a USB stick and turning them on. Because the OS and its apps are free, and because there are no finicky vendor relationships to manage, it Just Works. On some of those machines, installing a Windows OS fresh from a shrinkwrapped box was literally impossible -- you had to order a special manufacturer's version with all the right drivers to handle external CD drives or docking stations or what-have-you. And the free/open drivers also handled things like 3G USB adapters better than the official drivers (not least because they didn't insist on drawing a huge "WELCOME TO $SOME_STUPID_PHONE_COMPANY" box on the screen every time you connected to the Internet.)

At issue is a new facility called UEFI, which allows a computer's bootloader to distinguish between different operating systems by examining their cryptographic signatures. Read the rest

How food spherification works

On IO9, Esther Inglis-Arkell does a great job of describing the molecular gastronomy practice of "spherification," whereby food is liquefied and then coaxed into forming gelatinous spheres. It has its origin in a 1950s drug-delivery project from Unilever, but was revived by chef Ferran Adrià around 2003.

What spherification does is put back in what the manufacturers of sodium alginate take out. First, the food, whatever it is, is pureed until it's liquid. Then the calcium content of the food is determined. If the calcium content is high, adding sodium alginate will solidify the whole thing immediately. To high-calcium foods extra calcium chloride is added. To all other foods, sodium alginate is added. Then, as with all delectable meals, it's off to the centrifuge. The mixture gets centrifuged to remove any bubbles or impurities there might be in it. Once that's done, drops of the stuff are tossed into a bowl of liquid. If the food contains calcium chloride, the liquid will contain sodium alginate. If the food contains alginate, it will be tossed into liquid containing calcium.

Immediately, the process begins. The outer edge of the spherical drops is the front line. When the sodium alginates hit calcium ions, the ions bind the long strings together, until they form a kind of haphazard net of polymers. The outer layer of the gel solidifies before any of the inner liquid can leak out. Depending on the concentration of both chemicals, and the time spent in the 'bath,' the gel will either be a tiny skin, or an extremely firm layer.

Linux Foundation memo: how to make a computer that doesn't lock out GNU/Linux

UEFI is a new hardware standard nominally aimed at stopping malicious software, but it could also make it illegal to replace Windows or MacOS with GNU/Linux on your computer. The Linux Foundation has written a technical memo for hardware vendors explaining how they can ship PCs that still protect users from malware, without putting them in legal jeopardy for running free operating systems:

The recommendations can be summarized as follows: All platforms that enable UEFI secure boot should ship in setup mode where the owner has control over which platform key (PK) is installed. It should also be possible for the owner to return a system to setup mode in the future if needed. • The initial bootstrap of an operating system should detect a platform in the setup mode, install its own key-exchange key (KEK), and install a platform key to enable secure boot. • A firmware-based mechanism should be established to allow a platform owner to add new key-exchange keys to a system running in secure mode so that dual-boot systems can be set up. • A firmware-based mechanism for easy booting of removable media. • At some future time, an operating-system- and vendor-neutral certificate authority should be established to issue KEKs for third-party hardware and software vendors.

Anti-malware hardware has the potential to make it illegal and impossible to choose to run Linux

It's been years since the idea of "trusted computing" was first mooted -- a hardware layer for PCs that can verify that your OS matches the version the vendor created. At the time, TC advocates proposed that this would be most useful for thwarting malicious software, like rootkits, that compromise user privacy and security.

But from the start, civil liberties people have worried that there was a danger that TC could be used to lock hardware to specific vendors' operating systems, and prevent you from, for example, tossing out Windows and installing GNU/Linux on your PC.

The latest iteration of Trusted Computing is called "UEFI," and boards are starting to ship with UEFI hardware that can prevent the machine from loading altered operating systems. This would be a great boon to users -- if the PC vendors supplied the keys necessary to unlock the UEFI module and load your own OS. That way, UEFI could verify the integrity of any OS you chose to run.

But PC vendors -- either out of laziness or some more sinister motive -- may choose not to release those keys, and as a result, PC hardware could enter the market that is technically capable of running GNU/Linux, but which will not allow you to run any OS other than Windows.

What's more, UEFI may fall into the category of "effective access control for a copyrighted work," which means that breaking it would be illegal under the DMCA -- in other words, it could be illegal to choose to run any OS other than the one that the hardware vendor supplied. Read the rest

MIT Researcher records 90,000 hours of home video, analyzes the hell out of it

[Video Link]MIT researcher Deb Roy's presentation was probably my favorite at TED2011. The highlight of his presentation was when he played an audio file of his son learning how to say "water" over the course of the research project.

MIT researcher Deb Roy wanted to understand how his infant son learned language -- so he wired up his house with videocameras to catch every moment (with exceptions) of his son's life, then parsed 90,000 hours of home video to watch "gaaaa" slowly turn into "water." Astonishing, data-rich research with deep implications for how we learn. Deb Roy studies how children learn language, and designs machines that learn to communicate in human-like ways. On sabbatical from MIT Media Lab, he's working with the AI company Bluefin Labs.
