Smartphones Could Detect Earthquakes

A new phone app is said to help detect earthquakes and provide quicker warnings than is currently possible. The 'MyShake app' has many limitations, but could theoretically still save lives. The app uses the accelerometer that's built into most ... modern phones. It's a small gadget that measures movement in the phone along three axes (left-right, up-down, back-forth) and powers all sorts of features, including fitness tools and the way that displays automatically rotate and resize if you turn the phone from landscape to portrait or vice versa. The idea of MyShake is to constantly monitor ... (view more)

Apple Offers iPhone Data For Medical Research

Apple is making its technology available to medical researchers to conduct mass studies. Participation is entirely voluntary, and the company insists user privacy will be protected. The technology is called ResearchKit, and it's a set of tools ... available to researchers to make use of data gathered by smartphones that could relate to health and medicine. As well as collecting data from Apple products such as the iPhone, ResearchKit will be able to use data from fitness gadgets from other firms such as Fitbit. Using ResearchKit, researchers will be able to develop iPhone apps, even if they don ... (view more)

WiFi Virus Spreads Like Airborne Disease

Computer researchers have created an 'airborne' computer virus that takes advantage of WiFi (wireless Internet) routers. The point of the study is to highlight the many ways in which wireless routers are open to abuse. The research studied wireless ... access points, and was completed by the University of Liverpool. Access points are electronic devices that relay information from a local wireless network to another (typically the Internet). For example: a PC or laptop connected to a wireless router (which is then connected to the Internet) would be considered an access point. The goal of ... (view more)

Facebook Study Reveals Which Couples Will 'Make It'

Researchers say they can figure out when two Facebook users are in a relationship just by looking at their list of 'friends'. They also say it's possible to predict when a relationship will end. Often, it's easy to tell when Facebook users are in a ... relationship because many people display this information on their profiles. However, new research says relationships can be detected even without those vital details. The research is the work of Cornell University computer scientist Jon Kleinberg and Facebook engineer Lars Backstrom. They analyzed the Facebook accounts of 1.3 million people aged ... (view more)

'Balancer' Browser Tool Reveals Your Political Bias

Researchers in the United States have developed a tool that can help you get more balanced political information on the Internet. But it's not yet proven that it can change your mind. The idea is to counter the "echo chamber" effect. The theory is ... that people tend to look at online news sources and follow social media users who share their own views and attitudes. As a result, people tend to see a similar viewpoint all of the time, in turn reinforcing their prejudices and meaning they never have to see material that might challenge their stance. Over the long term, they get the false ... (view more)

Illegal Downloads Increase Despite Pirate Bay Ban

Law enforcement agencies around the world are taking steps to prevent the illegal distribution of copyright-protected materials through file-sharing sites like The Pirate Bay . However, new research from the Netherlands shows that illegal ... downloading has actually increased since that country took steps to block access to the controversial Sweden-based site. Back in 2012, Dutch courts ruled that Internet Service Providers in the Netherlands must make an attempt to block all access to The Pirate Bay. Those courts based their decision on reports indicating that over 90 per cent of the material ... (view more)

Twitter Could Help Predict Riots, Study Suggests

Researchers in the Middle East say Twitter could be a useful tool in predicting violent riots. The Qatar Computing Research Institute says that although you can't read too much into a single 'tweet' from a single user, when you gather the data from ... thousands of users you can detect certain trends. By piecing that data together, researchers say they can predict when and where violence will occur. To test the theory, the Qatar researchers developed what they call the 'Political Polarization Index'. They analyzed all Twitter posts by Egyptian users and gave each user a rating between 0 and 1 ... (view more)

Facebook Bad For Your Mental Health, Study Suggests

People who regularly use social networking site Facebook are prone to negative feelings, a new study finds. But there's some question over the cause and effect involved. Researchers at the University of Michigan studied 82 Facebook users with an ... average age of 19 to 20. The researchers started by asking the subjects a series of questions to check their levels of self-esteem and / or depression. They then sent the subjects a text message five times each day over a two-week period. (Source: plosone.org ) The message linked to a survey that asked the subjects whether they felt positive or ... (view more)

Bogus GPS Signal Sends Ship Off Course

Security researchers at the University of Texas have reportedly used global positioning system (GPS) technology to remotely take control of a ship. Shockingly, they pulled off the scheme without being detected by the ship's crew. Fortunately, the ... attack was part of a controlled experiment carried out with the permission of the ship's owners. The researchers were able to use bogus GPS data to control the ship's navigation. It's the first time researchers have been able to successfully alter GPS data rather than simply blocking or "jamming" a signal. The researchers say they were able to change ... (view more)

Smarter Data Handling Could Make Net Faster

Researchers at the Massachusetts Institute of Technology (MIT) say they've developed a system that could help speed up the Internet. The research is designed to find an alternative to the Transmission Control Protocol (TCP) system. TCP is the set of ... rules that govern the way data moves around the Internet. Whenever data travels online, it's broken down into small chunks known as 'packets' (in effect, info packets!). Often, these packets take different routes around the various connections that make up the net, then get reassembled at their destination. Net Currently Favors Accuracy Over Speed ... (view more)
