Should Internet communication services be redesigned so that law enforcement can carry out legally authorized intercepts?

This week's Question of the Week focuses on the redesign of some Internet communication services. Law enforcement officials want Congress to require all services that enable communications — including encrypted e-mail transmitters like BlackBerry, social networking Web sites, and “peer to peer” messaging software like Skype — to be technically capable of complying if served with a wiretap order. Law enforcement officials contend that imposing a mandate is reasonable and necessary to prevent the erosion of their investigative powers. Skeptics, including privacy and technology advocates, say that requiring interception capabilities would create holes that would inevitably be exploited by hackers.

What do you think? Should Internet communication services be redesigned so that law enforcement can carry out legally authorized intercepts?

Organic LED Light Source for Home Electronics, Medicine, and Clean Energy

Electronic products pollute the environment with a number of heavy metals before, during, and after they're used. In the U.S. alone, an estimated 70% of heavy metals in landfills come from discarded electronics. With flat screen TVs getting bigger and cheaper every year, environmental costs continue to mount.

Should smartphones be used as learning tools in the classroom?

This week's Question of the Week focuses on smartphones in the classroom. Ontario Premier Dalton McGuinty recently suggested students should be allowed to use smartphones in the classroom, saying that the devices have a variety of helpful educational tools -- calendars, planners, and browsers, for example -- and teachers should have the ability to make the call on evolving technologies. The Ontario Secondary School Teachers Federation, however, said the phones are too disruptive and that until they're actually part of lesson plans, they won't help with learning.

What do you think? Should smartphones be used as learning tools in the classroom?

Will 3D catch on in the long run, and will TV fans and movie buffs demand the technology?

This week’s Question of the Week concerns 3D. The technology offers moviegoers and TV fans an enhanced viewing experience, and many recent 3D films, including Avatar and Alice in Wonderland, have had box office success. Several 3D movies, however, have flopped, and according to a new Nielsen Co. consumer study, many respondents who experience the 3D television technology — and especially the glasses needed to see 3D images — have become less interested in buying a 3D set.

What do you think? Will 3D catch on in the long run, and will TV fans and movie buffs demand the technology?
