US court backs mobile phone privacy



The unanimous decision is a win for privacy advocates that argued searching mobiles was an unreasonable intrusion.
Chief Justice John Roberts wrote in his opinion that mobiles "hold for many Americans the privacies of life".

The high court had weighed appeals by two people convicted based on evidence found on their phones.
Both were convicted of crimes for which they were not initially arrested.

Phone picture of US Supreme CourtUnder the fourth amendment to the US constitution, police and other government officials generally need to obtain a warrant from a judge before they can conduct a search.
A warrant requires evidence that a crime has been committed by the suspect.

Justice Roberts wrote in his ruling for the court that constitutional protection applied to the contents of mobiles, as they "differ in both a quantitative and qualitative sense from other objects that might be carried on an arrestee's person".

"Modern cell phones are not just another technological convenience. With all they contain and all they may reveal, they hold for many Americans the privacies of life,'' he wrote.
"Our answer to the question of what police must do before searching a cell phone seized incident to an arrest is accordingly simple - get a warrant."

More than 90% of Americans own at least one mobile, according to the Pew Research Center. More than 12 million people were arrested in the US in 2012, according to FBI statistics.

The Supreme Court had previously ruled that during an arrest, police do not need a warrant to empty a suspect's pockets and examine whatever they find in order to ensure officers' safety and prevent the destruction of evidence.
But Wednesday's decision rules the contents of mobiles do not fall under that rationale. 

The case came to the US high court through two separate appeals.
In the first, prosecutors used video and photographs found on David Riley's smartphone to persuade a jury to convict him of attempted murder and other charges.

Riley had been driving on a suspended licence, and police found guns in his car and charged him with carrying a concealed weapon, then searched his phone.

In the second case, Brima Wurie was arrested on suspicion of selling crack cocaine. On grounds of "officer safety" police examined the call log on his mobile phone and used that information to determine where he lived.
When they searched that residence, with a warrant, they found crack cocaine, marijuana, a gun and ammunition.

Google: Self-driving Cars are Mastering City Streets

(CNN) -- Long a veteran of the highways of rural California, Google's self-driving car is working on becoming safer in the city.

Over the past year or so, Google has been fine-tuning how the software running its fleet of automated vehicles handles the complexities of stop-and-go driving in heavily populated areas.

Google's self-driving car includes laser technology that creates a 3-D map of its surroundings.

 "A mile of city driving is much more complex than a mile of freeway driving, with hundreds of different objects moving according to different rules of the road in a small area," Chris Urmson, the head of Google's self-driving-car project, said Monday in a publication. 

Urmson said engineers have improved the cars' software to recognize situations like pedestrian traffic, buses, stop signs held by crossing guards and hand signals made by cyclists.


And, he says, self-driving cars have the potential to handle all of that even better than we do.

"A self-driving vehicle can pay attention to all of these things in a way that a human physically can't -- and it never gets tired or distracted," Urmson wrote. "As it turns out, what looks chaotic and random on a city street to the human eye is actually fairly predictable to a computer."

'Miracle material' Graphene one step closer to commercial use

No one ever expected the humble pencil to kickstart a revolution. But, by peeling apart pencil graphite into atom-thick layers using regular adhesive tape, two Russian-born scientists, Andre Geim and Konstantin Novoselov, earned a Nobel Prize in 2010. With it, they sparked the beginnings of a material that could change the world.
 
It is no exaggeration to say that graphene, the substance that the two scientists -- along with others -- discovered in 2004, is a miracle material. Now a Korean research lab may have made the leap from theoretical to practical with the development of a new way to synthesize it, potentially on a commercial scale.
 Samsung potentially has a head-start in next-gen mobile technology, thanks to its development of a new way of synthesizing graphene.
The substance, "the perfect atomic lattice," boasts a number of hugely attractive properties, meaning it has the potential to be used in myriad industries, and for a huge range of purposes.

If that wasn't enough, it is also almost perfectly transparent, impermeable to gas, and its properties are, scientists say, easily alterable.
Graphene is one form -- an allotrope -- of carbon, the basis of all life on earth. More familiar carbon allotropes include diamonds and graphite. What makes it unique is its thinness -- at one atom thick it is as good as two-dimensional. Its flexibility means that it could potentially be used for flexible or wearable devices.

"Graphene has a lot of potential, especially in terms of industrial applications for optical and electronic devices," says Ping Sheng, a Professor of Nanoscience at Hong Kong University of Science and Technology.

"The caveat is really in the quality of the graphene that can be produced on a large scale ... If they can overcome that then it will be a big breakthrough."

Another byproduct of its remarkable thinness is its low weight. It could be used to create ultra-light components for, say, the aviation industry, dramatically reducing the weight of aircraft -- and thus significantly improving fuel efficiency -- without compromising strength or integrity.
The substance is so versatile that it has even been touted as the future of condoms. The Bill and Melinda Gates Foundation last year awarded a $100,000 grant to fund the development of graphene prophylactics.

Drawbacks
Currently, its limitations include the fact that its conductivity can't be turned "off," meaning that as a semiconductor it is useless, although researchers are experimenting with the substance to figure out a way around this problem. One possible fix could be to build artificial breaks in the substance, allowing for circuits to be opened and closed, or to alter its properties with the use of chemicals.
If this deficiency can be overcome, however, graphene could be used in a huge range of devices as a super-fast replacement for silicon transistors, which are already reaching their capacity. Graphene has one hundred times the electron mobility of silicon.
Another limitation comes in the form of its production -- currently it can only be synthesized in small crystals. While this is enough for researchers to test its properties and understand the tantalizing benefits of the material, it is not sufficient to produce it for mass commercial use. But with an announcement made last week, all this could change.
Public- and private-sector funding
Governments and the private sector are actively exploring the potential of the substance, with the EU devoting €1 billion ($1.3 billion) to it between 2013 and 2023, funding research which could potentially transform a range of sectors, including electronics, energy, health and construction.
The Samsung Advanced Institute of Technology last week announced it had developed "a breakthrough synthesis method" of producing graphene, and the hopes are that this will pave the way for the commercialization of the material. The results were published in the journal Science.

Samsung sees graphene as the "perfect material" for next generation device, and the breakthrough could have huge implications for its commercial production.

"This is one of the most significant breakthroughs in graphene research in history," researchers said in a statement released by the company. "We expect this discovery to accelerate the commercialization of graphene, which could unlock the next era of consumer electronic technology."

In partnership with with Sungkyunkwan University, the Institute has pioneered the growing of large-area, single crystal wafer scale graphene. Previously, small graphene particles had been combined to form large-area graphene, but the process diminished both the mechanic and electric effectiveness of the substance.

The material's conductivity would make charging a device take a matter of seconds, and its strength, durability and flexibility would allow Samsung to truly innovate with a whole range of new devices and ways to interact with technology.
It has not been revealed if Samsung plans to make the groundbreaking synthesis process public, a move that would rapidly accelerate the adoption of graphene into daily use.

However, Sheng thinks that it won't be long before the process is widely available. "I don't think they can keep it proprietary very long, even if they want to ... This will start many factories around the world doing the same thing."
