New Technique Targets C Code to Spot, Contain Malware Attacks

Researchers from North Carolina State University have developed a new tool to detect and contain malware that attempts root exploits in Android devices. The tool improves on previous techniques by targeting code written in the C programming language – which is often used to create root exploit malware, whereas the bulk of Android applications are written in Java.

Root exploits take over the system administration functions of an operating system, such as Android. A successful Android root exploit effectively gives hackers unfettered control of a user’s smartphone. (more…)

Studies in perception: At arm’s length: Plasticity of depth judgment

People have a distance at which they are best able to judge depth. That distance, it turns out, is dictated by how long people understand their arms to be. Researchers showed this in the Journal of Neuroscience by tricking subjects with virtual reality into thinking their reach was longer than it really was. The result? Their accurate perception of depth via sight moved outward and touch became more sensitive.

PROVIDENCE, R.I. [Brown University] — We need to reach for things, so a connection between arm length and our ability to judge depth accurately may make sense. Given that we grow throughout childhood, it may also seem reasonable that such an optimal depth perception distance should be flexible enough to change with a lengthening arm. Recent research in the Journal of Neuroscience provides evidence for these ideas with surprising findings: Scientists showed that they could manipulate the distance at which adult volunteers accurately perceived depth, both through sight and touch, by tricking them into thinking they had a longer reach than they really do.

„Erst denken, dann schreiben“: Über Twitter in der Politik

Bundestagsabgeordnete, die mit ihren Smartphones im Plenarsaal sitzen und ihre Meinung zu dem Gesagten noch während der Sitzung twittern, sind zum Alltag geworden in der deutschen Politik. Im Gespräch mit dem Politik- und Digitalberater Martin Fuchs wird deutlich, wie dieser Trend die politische Debatte beeinflusst und wie die demokratische Meinungsbildung durch soziale Medien profitieren kann – wenn sie ernst genommen werden.

politik-digital.de: Social Media sind im politischen Alltag der Bundesrepublik angekommen. Wie sind die Entwicklungen in der jüngeren Vergangenheit zu bewerten?

Martin Fuchs: Diese Entwicklung steht eng im Zusammenhang mit der sich verbessernden Verbreitung des Internetzugangs. Auf dieser Grundlage haben soziale Netzwerke eine größere Reichweite erhalten. Darin sehen die Politiker ein großes Potential, ihr Metier wieder attraktiv zu machen. Zum einen nutzen sie diese Plattformen dafür, um ihre Meinungen zu verbreiten. So tritt der Abgeordnete in direkten Kontakt zu den Bürgern, was den politischen Diskurs positiv beeinflusst. Zum anderen sind diese aber auch eine Möglichkeit, um Meinungsforschung zu betreiben. Allerdings ist es zeit- und auch kostenintensiv, zum Beispiel wenn Personal für diese Aufgaben eingestellt werden muss. (more…)

Smartphone as mentor: How tech could change behavior

ANN ARBOR — Funneling a steady stream of diversions straight to your pocket, smartphones are often cast as the ultimate distractors. But a University of Michigan engineering professor sees potential for them to be something quite the opposite.

What if they could act as mentors in mindfulness, helping users stay attentive in order to achieve particular goals? (more…)

Welchen Fisch zum Fest?

WWF: Silvesterkarpfen und Katerrollmops ökologisch unbedenklich

Neben der klassischen Weihnachtsgans gehören auch Lachs und Meeresfrüchte längst zum festlichen Menü an Weihnachten und zum Jahreswechsel. Wer auch der Meeresumwelt ein Geschenk machen möchte, greift beim Weihnachtseinkauf zu Lachs aus Biozucht oder MSC-zertifiziertem Wildlachs. Damit ist sichergestellt, dass der Lachs umweltverträglich gezüchtet wurde bzw. nicht aus überfischten wilden Beständen stammt.

Bei vielen „Edelfischen“ rät der WWF dagegen vom Verzehr ab: Die Bestände von Schwertfisch und Rotem Snapper stehen unter hohem Fischereidruck, außerdem enden beim Fang oft auch Meeresschildkröten und Delfine als Beifang an Langleinen und Treibnetzen. Ähnliche Probleme prägen die Fischerei auf Gelbflossenthunfisch, hier bieten jedoch Herkunft und Fangmethode eine gute Orientierung: Angelrute und Handleine sind traditionelle umweltverträgliche Fangarten, mit denen Fische einzeln gefangen werden und andere Meerestiere, wie Meeresschildkröten und Haie, verschont bleiben.

Mobile computing in the ‘bring your own device’ era

Early in September Yale passed a milestone in mobile computing, with a record 39,414 mobile devices connected to its wireless networks. As on most college campuses the growth of mobile computing at Yale has been explosive, from well under 10,000 devices three years ago to almost 40,000 today.

A recent Gartner study showed that smartphone ownership among college students went from 55% in 2011 to 62% in 2012, and the percentage of students using their smartphones for academic work doubled in the same period. The typical U.S. college student now routinely uses between 2-3 wireless devices, and higher education computing experts predict that average to grow to 3-4 devices over the next year. (more…)

Using earthquake sensors to track endangered whales

The fin whale is the second-largest animal ever to live on Earth. It is also, paradoxically, one of the least understood. The animal’s huge size and global range make its movements and behavior hard to study.

A carcass that washed up on a Seattle-area beach this spring provided a reminder that sleek fin whales, nicknamed “greyhounds of the sea,” are vulnerable to collision when they strike fast-moving ships. Knowing their swimming behaviors could help vessels avoid the animals. Understanding where and what they eat could also help support the fin whale’s slowly rebounding populations. (more…)

Ways Google Glass Would Be Great for Gaming

Many are speculating the possibilities for the new Google Glass – a wearable computer that displays a screen in front of your eye that you can control by voice command – in industries, such as medicine and education.

One industry in particular that has people excited about the possibilities for using the device is the gaming industry. The Google glass can take gaming to a completely different level in all genres of gaming.

Multiplayer system, role-playing (RPGs) and first-person shooting (FPS) games could potentially be more efficient to play and participate in. The glass right in front of your eye places you in the hub of the action, allowing players to nearly be face-to-face and eye-to-eye with the opponents in their games. What’s more, there is the potential of better accuracy when shooting, with the glass serving as your pinpoint target. (more…)
