It may not look like much when not in use, but that's your ticket to hologram-like communi...

Remember all those science fiction movies and television shows that depicted people in a future time, talking to life-sized holographic images? That time is now. A research team from Queen's University in Ontario has developed a video communications system that allows you to speak with an eerie three-dimensional representation of the person on the other end of the line.  Read More

Researchers are developing innovative ways to keep smartphones powered-up in the developin...

Smart phones are techno wonders, and they are also energy guzzlers, which is not a problem for people living in the developed world. However, their high energy requirements has stymied the adoption of mobile internet services in developing countries where mobile internet can be a real lifeline. In Africa, for example, few people can access the internet from a wired connection but 90 percent of the population lives in areas with mobile phone network coverage. There’s one problem though. Access to the power grid in Africa is limited.  Read More

Japanese telecommunications giant NTT is developing a videoconferencing system that literally turns heads. In an attempt to more accurately give the feeling of a face-to-face conversation between more than two people, the MM-Space system features displays that physically mimic the head movements of the person being displayed on screen.  Read More

Cellphones have an increasing role to play in our breaking apart (Photo:

Cellphones play an obvious role in dating, meet-ups, and generally keeping in touch ... but they also have an increasing role to play in our breaking apart. Data snaffled from smartphones is flourishing as divorce evidence, and on the other side of the ledger, apps exist to help in the process of hanging up marital connections - there are apps to initiate, manage and survive a divorce as well as apps for assessing the costs and scheduling time with kids afterwards.  Read More

While cop shows have shown us that it’s easy for service providers to track a person’s location via their mobile phone, researchers at the University of Minnesota have revealed it’s also an easy task for hackers. Using a cheap phone and open source software, the researchers were able to track the location of mobile phone users without their knowledge on the GSM network, which is estimated to serve 80 percent of the global mobile market.  Read More

Onur Hamza Karabey and his prototype liquid crystal antenna

Vehicles such as cars, ships and aircraft need to stay in stable contact with earth-orbiting satellites, in order for on-board functions like GPS, internet access and satellite television reception to work properly. As the vehicles move, their orientation to those satellites changes, so electronically-redirectable phased-array antennas are typically required. According to scientists at Germany's Technische Universität Darmstadt, however, these are "either very expensive or only sluggishly redirectable." That's why doctoral candidate Onur Hamza Karabey is working on a low-cost, fast-performing alternative - a liquid crystal antenna.  Read More

Will members and investors 'like' Facebook becoming a publicly listed company (Photo: Shut...

Facebook has filed an S-1 document with the United States Securities and Exchange Commission announcing its intention to sell shares to the public. The eagerly anticipated move by the world’s dominant social networking site sees Facebook’s books open to potential investors – and the just plain curious - for the first time. Although the IPO will mean the internet giant will answer to shareholders and a board, the stock structure will see Facebook founder Mark Zuckerberg controlling 57 percent of voting shares.  Read More

A number of high profile websites are going dark today to protest the proposed Stop Online Piracy Act (SOPA) and PROTECT IP Act (PIPA). The bills are designed to protect intellectual property holders by toughening measures against copyright infringers. Opponents say that aspects of the bill pose grave threats to free speech and internet entrepreneurship, with some high profile webmasters claiming that the bill, if passed, would threaten the very existence of their sites despite not hosting copyright-infringing material directly. Wikipedia, Reddit and Boing Boing are among the sites effectively shutting down today.  Read More

China’s independent Beidou satellite navigation system has been operating since 2000. Consisting of just three satellites (and one backup), that first generation system offered only limited coverage to customers in China and neighboring regions. Now, to end any reliance on the US-maintained Global Positioning System (GPS), the second generation of the Beidou system has begun operations. The system currently consists of 10 satellites and covers the Asia–Pacific region, with the number of satellites gradually increasing to a total of 35 that will cover the entire globe by 2020.  Read More

An international team of researchers has set a world record two-way data rate over long di...

An international team is claiming a data transfer record that puts any home broadband connection to shame. At last month’s SuperComputing 2011 (SC11) conference in Seattle, researchers reached transfer rates of 98 gigabits per second (Gbps) between the University of Victoria Computing Centre located in Victoria, British Columbia, and the Washington State Convention Center in Seattle. Coupled with a simultaneous data rate of 88 Gbps in the opposite direction the team reached a two-way data rate of 186 Gbps to break their own previous peak-rate record of 119 Gbps set in 2009.  Read More
