Researchers at the University of California at Irvine (UCI) have discovered how to increase the tensile strength of nanowires that could be used to make lithium-ion batteries last virtually forever.
The discovery could lead to vastly longer lifespans for batteries in computers, smartphones, appliances, cars and spacecraft. The findings were published today in the American Chemical Society’s Energy Letters.

When it comes to the presidential election, it can be mighty challenging to separate the wheat from the chaff. I’m not talking about the actual candidates (though that poses challenges as well), but rather the onslaught of news, opinion and polling that accompany the whole process. Sometimes it feels like you’re standing in a hailstorm of election coverage with an umbrella made of tissue paper.

Newly discovered vulnerabilities in the way Android processes media files can allow attackers to compromise devices by tricking users into visiting maliciously crafted Web pages.The vulnerabilities can lead to remote code execution on almost all devices that run Android, starting with version 1.0 of the OS released in 2008 to the latest 5.1.1, researchers from mobile security firm Zimperium said in a report scheduled to be published Thursday.
The flaws are in the way Android processes the metadata of MP3 audio files and MP4 video files, and they can be exploited when the Android system or another app that relies on Android’s media libraries previews such files.
The Zimperium researchers refer to the new attack as Stagefright 2.0 and believe that it affects more than 1 billion devices.
