Segment 1: Duke researchers have built a 50-gigapixel camera. That's like 6,000 decent cell-phone cameras, all stitched together.

Segment 2: Always be sure to save your photos from your phone or digital camera to your computer's hard drive, and back up that hard drive to DVDs or portable hard drives.

A caller wanted to know how to get Internet access in a part of Carlisle where he can't get DSL or cable access. The rapid rollout of 3G and 4G wireless Internet access via phone providers like Verizon, US Cellular, and AT&T really renders most other options obsolete. They still tend to place limits on the amount of data you can download, so you'll have to go easy on downloading videos, but those broadband plans are probably the best options for most people. If you're just going to leave it at home, consider getting one of the dedicated hotspots that are available.

Segment 4: This coming week will be Lightning Safety Week. Be sure your electronics are protected from lightning via a surge suppressor. Check those suppressors out every few months -- they don't last forever, and if the "protection" light goes out, your electronics are no safer than if they'd been left plugged straight into the wall. And be sure that you've protected your data, too, by saving the important stuff to something like a DVD or a portable hard drive that isn't plugged-in.

And the electric car has gone high-end with the new Tesla sedan. It'll set you back $50,000 to $100,000 to show all your friends how technologically sophisticated and eco-friendly you are.

Thanks for listening this week! - Brian Gongol
