Cells use sugars to communicate at the molecular level -- ScienceDailyUsing engineered synthetic cells as a model system, lead author Cesar Rodriguez-Emmenegger, a former member of Percec's group, now at Aachen, discovered a way to directly study cell membranes using a method called atomic force microscopy. This approach generates extremely high-resolution scans that reveal shapes and structures at a scale of less than a nanometer, nearly 10,000 times smaller than the width of a human hair. Percec's group then built a model that computes how the structural images relate to the cell's function. The study is the first example of a diffraction-like method that can be done on whole synthetic cells. Using this new method, Percec's group discovered that a lower concentration of sugars on a cell membrane's surface led to increased reactivity with proteins on the membranes of other cells.
Facebook Open Sources Its AI Hardware as It Races Google | WIREDBig Sur includes eight GPU boards, each loaded with dozens of chips while consuming only about 300 Watts of power. Although GPUs were originally designed to render images for computer games and other highly graphical applications, they’ve proven remarkably adept at deep learning. […]Traditional processors help drive these machines, but big companies like Facebook and Google and Baidu have found that their neural networks are far more efficient if they shift much of the computation onto GPUs. […] After 18 months of development, Big Sur is twice as fast as the previous system Facebook used to train its neural networks.
We’re rushing headlong into the era of cheap cell phones. The peace dividends of the smartphone wars mean you can buy a pretty amazing piece of hardware for what many people spend on lattes each month. That Alcatel has 4G, a quadcore processor, a 13-megapixel camera, and it plays 1080P video. It runs Android 4.2, which isn’t completely current but isn’t totally out of date either, and you can grab one for as little as $80 without a contract. That $129 Moto E ($79 if you get a contract, which you shouldn’t) runs Android 4.4.2, sports a Gorilla Glass screen, has an all-day battery and is even water resistant.
Alice never could quite make out, in thinking it over afterwards, how it was that they began: all she remembers is, that they were running hand in hand, and the Queen went so fast that it was all she could do to keep up with her: and still the Queen kept crying `Faster! Faster!' but Alice felt she could not go faster, thought she had not breath left to say so. The most curious part of the thing was, that the trees and the other things round them never changed their places at all: however fast they went, they never seemed to pass anything. `I wonder if all the things move along with us?' thought poor puzzled Alice. And the Queen seemed to guess her thoughts, for she cried, `Faster! Don't try to talk!' Not that Alice had any idea of doing that. She felt as if she would never be able to talk again, she was getting so much out of breath: and still the Queen cried `Faster! Faster!' and dragged her along. `Are we nearly there?' Alice managed to pant out at last. `Nearly there!' the Queen repeated. `Why, we passed it ten minutes ago! Faster! And they ran on for a time in silence, with the wind whistling in Alice's ears, and almost blowing her hair off her head, she fancied. `Now! Now!' cried the Queen. `Faster! Faster!' And they went so fast that at last they seemed to skim through the air, hardly touching the ground with their feet, till suddenly, just as Alice was getting quite exhausted, they stopped, and she found herself sitting on the ground, breathless and giddy. The Queen propped her up against a tree, and said kindly, `You may rest a little now.' Alice looked round her in great surprise. `Why, I do believe we've been under this tree the whole time! Everything's just as it was!' `Of course it is,' said the Queen, `what would you have it?' `Well, in our country,' said Alice, still panting a little, `you'd generally get to somewhere else -- if you ran very fast for a long time, as we've been doing.' `A slow sort of country!' said the Queen. `Now, here, you see, it takes all the running you can do, to keep in the same place. If you want to get somewhere else, you must run at least twice as fast as that!'
Unfortunately, since “good design” is defined by the user it’s intended for, it’s not just about creating more, and there is no algorithmic “law” for how to get it. It suffers from the phrase that all technologists and investors hate to hear, which is “… it depends.” Whether we want “more” or “less” doesn’t have a single right answer. An example I like to use is about doing the laundry versus eating a cookie. You always want less laundry, but more cookies. One person’s laundry is another’s cookie. And so on.
By 2017, an amount of data equivalent to all the films ever produced will be transmitted over the internet in a three-minute period, according to Cisco, a manufacturer of communications equipment.Internet traffic today per person is measured in gigabytes, with six gigabytes of information exchanged per human per year. In 2017, that number will have risen to 16. By then, global data will be counted in zettabytes – roughly one trillion gigabytes.
