Submission + - Silicon Nanoparticles Used to Create a Super-Performing Battery (gizmag.com)

Zothecula writes: In some peoples’ opinion, electric cars won’t become truly viable until their batteries offer a lot more driving range, and can be recharged much more quickly than is currently possible. Well, those people may soon be getting their wish. Scientists at the University of Southern California have developed a new type of lithium-ion battery, that they claim holds three times as much energy as a conventional li-ion, and can be recharged in just ten minutes.

Submission + - Most Americans Think Cyber Warfare Is Imminent (net-security.org)

Orome1 writes: A national survey of Americans shows a majority fear that cyber warfare is imminent and that the country will attack or be attacked in the next decade. Americans also want to see more done in both the public and private sector, with the government leading the way in setting standards and ensuring that important networks are protected. Given this strong level of support across age groups and demographics, we may see cyber security move up the list of critical policy and legislative proposals. 62 percent, say government should be responsible for protecting U.S. businesses and corporations from cyberattacks.

Submission + - Could Smart-Watches Replace Passwords as Authenticators? (threatpost.com)

Gunkerty Jeb writes: Good passwords are hard to remember while passwords that are easily remembered are often just as easily guessed. Therein lies the reason passwords are such a security headache. The race to replace passwords is ever-present in the security industry, and the newest entrant is the smart-watch.

“If the [iWatch] would do nothing but free me from having to enter pass codes, I would buy it even if it couldn’t tell the right time!” says Bruce Tognazzini, usability engineer and human-computer interaction expert.

Tognazzini is perhaps best known for designing Apple’s very first human interface. Yesterday he published an article on his personal blog exploring the possible applications of Apple’s rumored iWatch. The most interesting application, at least in the context of security, is the idea that the iWatch (or any smart-watch for that matter) could somehow replace the password.

Submission + - 17-year-old Rutvik Oza Solves an Unsolved Problem in Mathematics (yahoo.com)

An anonymous reader writes: An Indian teen has recently proposed a solution to an unsolved problem in mathematics. The 17-year-old young achiever, Rutvik Oza, a student of The H. B. Kapadia New High School, from Ahmedabad, Gujarat has now put a full stop to another open problem in the field of maths by providing a closed formula for the problem called Reve's Puzzle (also commonly known as the 4-peg Tower of Hanoi Problem).

When asked about how was he feeling, "Thrilled! I really didn't realize at first that the problem that I had solved was an open problem in mathematics. It was only later that I reckoned after doing some resourcing on the web, that it was an open problem," said Oza. Brought up in a middle class family, the teen dedicates his achievement to his father, Mahesh Oza, "It's all due to my father. He sowed the seeds of mathematics in me from my childhood. I dedicate this to him." he says. "It almost took me a week's time to get to the formula. It involved data analysis and pattern recognition," said Rutvik Oza.

When asked about his favorite maths giant, he said, "Newton, Ramanujan, Gauss and a long list of others to follow. There are many. It gives me goosebumps when I think about those greats.

"Mathematics interests me a lot. May it be any area of it — arithmetic, algebra or geometry. I love them all. It strengthens the faculties of originality, creativity and novelty in one's brain. Memorizing it won't help. That's the way it's taught in our schools here. I criticize that method of teaching fervently. Hardly any real mathematics is taught at the schools. I do not consider the schools responsible for it but yes, the entire system is definitely at fault," he added. When asked for a message that he wished to give his fellow teenagers, he said, "Do what you love! Follow your dreams. Expect for no support from anybody and overcome all obstacles that hinder you. No other mantra."
