On paper, collecting the sun's energy is a pretty great idea -- but most solar panels suffer from relatively low photovoltaic efficiency. On average, most panels will collect less than 20-percent of the light that hits it. Can we do better? Absolutely: but we'll need more Blu-ray discs. According to researchers at the Northwestern University of Evanston, Illinois, the microscopic hills an valleys found on a Blu-ray disc are surprisingly adapt at trapping light. On a video disc this talent is wasted, but when the pattern is cast, molded and transferred to a polymer solar cell, it becomes a series of quasi-random nanostructures that increase photovoltaic efficiency by about 22-percent. The research, which was published in Nature Communications earlier this month, is just a proof of concept -- but if further research proves fruitful the "Blu-ray trick" could serve as a shortcut to creating more efficient solar cells.

Sony's recently unveiled full-frame, mirrorless shooter, the A7 II, made a number of people quite excited when it was announced last week. Back then, though, the electronics company only revealed pricing and availability for Japan. Good news: Sony announced today that its A7 II will be coming to the US on December 9th, priced body-only for $1,700; there's also a kit that's $2,000, which includes an FE 28-70mm, f/3.5-f/5.6 OSS zoom lens. This price tag is similar to what we saw with the original A7 camera, and that's largely due to the upgrades not being particularly huge. Still, the new A7 II does feature a novel 5-axis, in-body stabilization system, one that Sony claims can adjust itself to many different types of shakes whilst shooting photos and video. Above all, let's not forget the main attraction here is that 24.3-megapixel full-frame sensor -- especially when you think about the compact package it comes in.
I basically live in Google's Chrome web browser. It's a decision I made to save my sanity when it became part of my job to change laptops every few weeks. No need to back up files that way! But it made me wonder how well I could live with only Chrome—if I could replace my laptop with a Chromebook instead.
If you're doing some research on popular "superfoods" and you're wondering which ones may have some credibility, this interactive chart shows which ones have the most scientific evidence to back them up based on studies and research.

Alas, our Galaxy Note 4 giveaway has run its course, but don't be too downhearted if you missed out. This week, we've got one of GoPro's new Hero4 Black Edition action cams to offload, and the timing couldn't be better if you've got a shredding adventure planned this ski season. The top-of-the-range GoPro, which can record gorgeous 4K video at 30 fps, has been supplied by our generous friends at Tagstr, the media-centric social network that uses hashtags to blend the photo, video and audio content of users into "shared moments." A few new features have been added since we last caught up with Tagstr, too, including support for multiple file uploads and the ability to import media from Facebook, Twitter and Instagram to share on Tagstr. As per usual, UK residents can enter the GoPro giveaway up to three times via the Rafflecopter widget below. After they've read the rules, that is.
