Recharge your phone in 30 seconds? Israeli firm says it can
 |

Using nano-technology to synthesize artificial molecules, Tel Aviv-based StoreDot says it has developed a battery that can store a much higher charge more quickly, in effect acting like a super-dense sponge to soak up power and retain it.
While the prototype is currently far too bulky for a mobile phone, the company believes it will be ready by 2016 to market a slim battery that can absorb and deliver a day's power for a smartphone in just 30 seconds.
"These are new materials, they have never been developed before," said Doron Myersdorf, the founder and chief executive of StoreDot, whose investors include Russian billionaire and Chelsea soccer club owner Roman Abramovich.
The innovation is based around the creation of "nanodots", which StoreDot describes as bio-organic peptide molecules. Nanodots alter the way a battery behaves to allow the rapid absorption and, critically, the retention of power.
The company has raised $48 million from two rounds of funding, including backing from a leading mobile phone maker. Myersdorf declined to name the company, but said it was Asian.
With the number of smartphone users forecast to reach 1.75 billion this year, StoreDot sees a big market, and some experts think that -- with more work -- it could be on to a winner.
"We live in a power hungry world ... people are constantly chasing a power outlet. StoreDot has the potential to solve this real big problem," said Zack Weisfeld, who has worked with and evaluated ventures in the mobile phone sector globally.
"They still have some way to go, to deal with size of battery and power cycle rounds, but if solvable, it's a very big breakthrough," he told Reuters. A power cycle round refers to the number of times a battery can be re-charged in its lifetime.
Myersdorf said a fast-charge phone would cost $100-$150 more than current models and would ultimately be able to handle 1,500 recharge/discharge cycles, giving it about three years of life.
He hopes to use the same technology to create a car battery that recharges in two or three minutes, rather than current models which commonly need to be charged overnight.

People Are Flipping Out Over This Super-Sophisticated Spy Software
Symantec believes Regin was likely created for cyber espionage purposes by a nation state, although it didn't suggest which government was responsible for it.
“Regin is a complex piece of malware whose structure displays a degree of technical competence rarely seen,” Symantec wrote in a report published on Sunday. “Its capabilities and the level of resources behind Regin indicate that it is one of the main cyberespionage tools used by a nation state.”
Symantec says Regin was first detected in 2008, but disappeared three years later, only to resurface in 2013. Regin has attacked all kinds of businesses, including telecoms, hospitality, and airlines, but nearly half of it targeted private individuals and small businesses. Russia and Saudi Arabia were the two hardest hit countries, each accounting for 28% and 24% of the attacks respectively, but it’s also been spotted in Mexico, Ireland, and India.
In a follow up report on Monday, another IT security lab, Kaspersky Labs, said it’s been tracking Regin for the past two years. It said the victims of Regin were mostly seen in telecom operators, government institutions, multinational political bodies, or financial/research institutions. It says the two main objectives of the attacks were “intelligence gathering” and “facilitating other types of attacks,” with 14 countries being identified as victims of Regin so far. Like Symantec, Kaspersky concluded, it’s likely Regin is “supported by a nation-state.”
Although none of the reports named which nation-state is likely responsible for Regin,Re/code pointed to a couple reports (by The Intercept and the Germany magazine Der Spiegel) as hinting that the NSA and the UK’s intelligence agency GCHQ may have a hand in it.

Twitter CFO Has Oops Moment by Mistakenly Tweeting About Deal
Nov. 25 (Bloomberg) -- Twitter Inc. has tripped up one of its top executives.
Chief Financial Officer Anthony Noto yesterday publicly tweeted about a plan he has to buy a company, including how he wanted to help make the deal happen at a meeting in mid- December. The message was posted on the microblogging service before it was deleted, with Twitter spokesman Jim Prosser confirming that Noto was trying to send the message privately.
“I still think we should buy them,” Noto tweeted. “He is on your schedule for Dec 15 or 16 -- we will need to sell him. I have a plan.”
It’s unclear who Noto was trying to send a message to or which company he’s interested in purchasing. Prosser declined to comment further.
The incident shows that even top members of Twitter’s executive team, who are on a mission to better explain the company’s product potential to Wall Street, sometimes have trouble using the service. The slip-up is so common that it has a name -- a “DM fail,” for “direct message fail.”
Such DM fails have happened on a relatively regular basis. In a high-profile Silicon Valley DM fail in 2010, startup investor Dave McClure mistakenly publicly tweeted that another Silicon Valley investor, Ron Conway, was throwing him under the bus over allegations that he was working with others to control the market for financing startups.
Early Adopter
Improving the way private and public messaging works is one of Twitter’s top goals for its product, executives said at a meeting with investors earlier this month.
Noto, previously a technology banker at Goldman Sachs Group Inc. and a former CFO at the National Football League, was an early adopter of Twitter, joining in 2009 when few other bankers used the service. Twitter has since become more acceptable in financial circles, especially when the Securities and Exchange Commission said in 2013 that it was an approved way for companies to distribute new information.
Noto took on the CFO role at Twitter in July. He led the San Francisco-based company’s effort to raise $1.8 billion in convertible debt in September, which Twitter said it would use so it can be opportunistic about dealmaking.
“Anthony’s ability to come up to speed quickly has been just delightful,” Twitter Chief Executive Officer Dick Costolo said in an interview in October. “The rigor that he brings to everything he does is fantastic and causes everyone he works with to make sure they’re being just as rigorous as he is. It ups everyone’s game.”
