Yahoo spends 'millions' on UK teen Nick D'Aloisio's Summly app

Nick D'Aloisio: "The idea came from revising for my exams"

An app created by a UK teenager has been acquired by web giant Yahoo in a deal the BBC understands to be worth "dozens of millions" of pounds.

Seventeen-year-old Nick D'Aloisio's Summly app summarises news stories from popular media companies.

Neither company would disclose the terms of the deal publicly.

The app itself will now close, but its features will be used in mobile products at Yahoo, where Mr D'Aloisio has been given a job.

He will be joined by several of Summly's "top staff" in new roles at Yahoo in the next few weeks.

The app launched when Mr D'Aloisio was aged just 15, and soon attracted more than £1m of investment. He is now likely to be one of the world's youngest self-made multi-millionaires.

Speaking to the London Evening Standard, the Wimbledon-based teen said: "I like shoes, I will buy a new pair of Nike trainers and I'll probably get a new computer, but at the moment I just want to save and bank it.

"I don't have many living expenses."

'Fantastic team'

In a note on the Summly blog, Mr D'Aloisio wrote on Monday: "When I founded Summly at 15, I would have never imagined being in this position so suddenly.

"I'd personally like to thank Li Ka-Shing and Horizons Ventures for having the foresight to back a teenager pursuing his dream. Also to our investors, advisers and of course the fantastic team for believing in the potential of Summly.

"Without you all, this never would have been possible. I'd also like to thank my family, friends and school for supporting me."

Yahoo's senior vice president of mobile, Adam Cahan, said the company was "excited" to have Mr D'Aloisio and his colleagues on board.

"For publishers, the Summly technology provides a new approach to drive interest in stories and reach a generation of mobile users that want information on the go," he wrote.

Less enthusiastic about the acquisition was app developer Little Fluffy Toys.

The London-based company was commissioned by Mr D'Aloisio to create an Android version of the Summly app - which was days away from launch.

Little Fluffy Toys director Kenton Price - who is also contracted by the BBC - said that his firm was told the Yahoo deal was on the cards, but was "disappointed" the app would now never be released.]]> http://www.bbc.co.uk/news/technology-21924243

According to the report from Business Insider (via Sunshine Coast Daily), the controversial and eccentric billionaire has been in serious discussions with the people who successfully cloned Dolly the sheep to work the same magic from dinosaur DNA. Palmer's endgame, naturally, is to let this scaly abomination roam free in a Jurassic Park-type sanctuary at his Palmer Resort in Coolum.

This isn't Palmer's only outlandish project currently in the works. He's also planning to build a 21st century replica of the Titanic. Whether these wild escapades will ever see the light of day remains to be seen, but in any case you've got to admire the man's sense of scope.

So far, Palmer has refused to comment on the rumors of his Hammond-esque aspirations, but if I were you I would definitely stay tuned.]]>

Video Gamers vs Scientists

Foldit is an online game that rewards you for figuring out how proteins fold. Earn points and change science forever. Seriously.

When someone whines that your playing video games is a waste of time, tell them you’re doing it for science. Researchers at the University of Washington have successfully leveraged the power of gamers to solve a biochemical puzzle: the structure of a complex protein related to the development of AIDS. By playing an online game called Foldit, teams of average citizens were able to make a breakthrough discovery in how this protein was shaped even though scientists had stumbled over the question for more than a decade. A combination of computer-created predictions and human 3D spatial reasoning transforms simple game playing into a mighty problem solving engine. Their discovery could help develop new anti-viral drugs for HIV. Watch how Foldit is played in the video below. While applications are likely to remain limited for years to come, programs like Foldit demonstrate the vast potential of crowd-sourced solutions in science. Never doubt it – video games can be powerful tools for change.

Researchers from the University of Washington described their unique method for solving the structure of the AIDS related protein in a recent report published in the journal Nature Structural and Molecular Biology. The compound in question was Mason-Phizer Monkey Virus (M-PMV) a retroviral protease that affects how the HIV strains mature and replicate. Like so many proteins, M-PMV’s crystalline structure is determined by very complex interactions between the amino acids in the molecule, as well as preferences for parts of the protein to avoid or attract water in its environment. Predicting how proteins fold up is a computer-heavy problem, and various groups have explored distributed computing solutions so that people all over the world can donate processor time towards determining protein structures.

Foldit has a very similar goal, only it’s using your brain, not your computer to help it figure out how proteins fold. In the style of a game, Foldit players are rewarded points for finding solutions to protein folding problems. There are always many different possible solutions, so Foldit rewards players, or teams of players, based on various requirements set by the game designers in the University of Washington computer science department. Essentially players look at complex proteins and use their 3D spatial reasoning skills, as well as healthy doses of trial and error, to find the the folding pattern that gives them the most points. It’s up to the UW team to determine how to award points in a way that makes the gamers’ efforts most useful.

In this study, University of Washington researchers determined that there are some conditions in which Foldit doesn’t work very well. Sometimes players get stuck pursuing dead-ends, other times they try to tweak a possible solution when they really need to make big changes to find the ideal answer. The Foldit puzzles in this study gave players starting points (called Rosetta structures) as well as the means to manipulate portions of the protein and compare them to earlier (validated) solutions. By changing the starting points, and giving players more freedom in exploring the possible folding patterns, the University of Washington enabled Foldit teams to get very close to finding the M-PMV structure. The gamers’ answers were so good that UW could then step in and use more traditional computer driven methods to find the finalized solution to the problem. Scientists had been working on M-PMV for years, this new style of guided-gaming figured it out in just three weeks.

It’s tempting to call the Foldit participants “untrained” or “typical video game players” because that makes for a good story. The truth is, however, that part of what Foldit does is teach you how to solve protein folding problems. It just does it in a way that you’ll find fun and challenging. It’s not that the University of Washington isn’t training the thousands of players who participate in Foldit, it’s that the training is so vastly different than normal scientific education. You don’t have to know why some atomic bonds lead to lower energy states when arranged in new patterns, you just have to play with these twisted proteins until you get enough points to win.
In the short term, the combination of human and computer processing that the University of Washington demonstrated could be put to extraordinary use. Humans have 3D understanding that computers just can’t handle yet, and computers have the number crunching capabilities that humans can’t possibly compete with. Put the two forces together and you’ll find new avenues for anti-viral medications (as with the M-PMV case) or possibly solve any number of other biochemical mysteries. We’ve seen similar pairings of human and computer expertise suggested for things like image tagging. There’s a whole application space waiting to be explored by inserting large numbers of humans into a problem solving system when computer power alone doesn’t cut it. Video games are a great tool for leveraging the human mind, especially as massive multiplayer online games and other internet entertainment are teaching us to enjoy solving challenges in crowd-sourced environments simply for the sake of earning more points (and prestige).

Looking further down the line, however, intellect-harnessing video games like Foldit are only going to be useful as long as there are skills that human brains possess that computer processors do not. We’ve probably got several decades of that being the case, but eventually it will change. So for now we should really enjoy the power of video games. Used correctly they can transform even the most lackadaisical layabout into a mighty instrument of science. So your mother was wrong: you’re not a coach potato, you’re a biological processor that really enjoys its work.
Speaking of which, there’s some scientific work I really need to get done. Anybody know the cheat codes to Ebola?]]>
