New nanoneedle technique probes inner workings of human skin

How does our top layer of skin -- the thin stratum corneum -- manage to keep water inside our bodies and microbes out, all while maintaining strength and elasticity, at just a fraction of the thickness of a sheet of paper?

In the first tests of its kind, scientists at the University of Bath are using a tiny "microneedle" with atomic force microscopy to probe the surface of the top layer of human skin and solve some of these mysteries.

Until now, researchers were able to use this form of microscopy only to analyze the surface of corneocytes, the cells that form the outer layer of the epidermis. Now, by adding a nanoneedle to the end of the probe, they can delve below the surface and shine a light on the cell structure within.… Read more

NanoGlass is a poor geek's stripped-down Google Glass

Now that Google Glass is in the hands of developers, it seems like everybody wants a smartphone connection on their specs. That pesky $1,500 price tag is a little annoying, though. Let's say you don't need all the fancy Glass features, like an eyeball-level display, camera, directions, search, and voice commands. If you're satisfied with just notifications, then you may soon be able to connect your smartphone to your glasses for $25.

The NanoGlass Indiegogo project from EmoPulse consists of a small Bluetooth device that attaches to the side of a pair of glasses. A fiber optic strip extends toward the front, just enough to show up in your peripheral vision.… Read more

Always On torture test giveaway: iPod Nano and iPod Shuffle

Over the years, it seems the iPhone has made the use of iPods a tad redundant. However, iPods keep stealing the spotlight at Always On because they're just so darn tough! Every time we put an iPod through the usual measures, it comes through with flying colors. After our children, Cheeto, and fruit-punch induced torture test for the iPod Touch last season, we had extremely high expectations for these two at Mt. Shasta Ski Park. Those expectations were greatly exceeded, to say the least.

But now it's your turn to put an iPod through its paces. Maybe you'… Read more

Why the 2011 iPod Nano is still the sexiest smartwatch of all

After reviewing a handful of the latest and greatest smartwatches, I discovered something shocking. Out of my old electronics drawer I pulled out my iPod Nano, the 2011 clip-on MP3 player that's no longer even sold by Apple. It's attached to a Hex Nano metal watchband. I wore this for over a year, and was so in love with the idea of an Apple smartwatch that I was willing to forgive its limitations -- and that it wasn't really all that smart.

All of these smartwatches have arrived, and I've worn them. Yet, when I slip … Read more

Always On: Best of Season 3

Well, folks, it's about that time again. That time when we head out into the world to get our hands on today's hottest gadgets and to explore the promising technologies of the future. And, of course, we'll keep an eye out for some clever ways to destroy those hottest gadgets, too. But, in the meantime, we've mustered up our favorite segments of Season 3 to make the wait for Season 4 less grueling.

First up, we head back to Mount Shasta Ski Park to watch Molly rev a snowmobile over the poor Kindle Fire, Nokia Lumia 920, … Read more

When will Apple kill the iPod?

Physical music formats were so 20th century, so we put our music on computers. But even that was too much of a burden, so music is going up, up, and away, into the cloud and streaming. The iPod Classic is firmly rooted to the ground, and I like it that way.

I can live without Siri, iCloud, a camera, iOS 6, a Lightning connector, Bluetooth, AirPlay, or any of that jazz to keep the Classic's 160GB storage capability, and the Classic's "classic" 30-pin connector that still works with gazillions of docks and accessories. Is there another … Read more

Nine things the iWatch (or any other smartwatch) needs

I've lived with a smartwatch, in one form or another, for several periods over the past few years. Recently, with the Martian Passport. Further back, with the iPod Nano and a Hex wristband. Before that, a SPOT watch.

I love the idea of a smartwatch. Certainly, so does the media as of late. Bloomberg reports and iWatch rumors galore, plus various wearable watch-type items at January's CES, have started to give this territory the sense of a category.

Between the Martian and the Nano watch, I loved aspects of each -- and also found them both lacking. There'… Read more

Episode 29: Hot phones in cold Barcelona

Barcelona is the place to be, and not just for the cafe con leche, the jamon iberico, or the incredible melted-stone facades of such Gaudi creations as the Sagrada Familia or the Casa Mila. Forget all that nonsense. It's all about the phones.

Mobile World Congress just wrapped in Barcelona, and with it came a bevy of new product announcements, ranging from Ubuntu and Firefox operating systems to new Samsung tablets, new phablets from LG and ZTE, a new Wi-Fi coffee-maker from Qualcomm, and...well, no, no Samsung Galaxy S4. That's next week. But this week's episode … Read more

For an iWatch to kick butt, Apple must innovate in batteries

If Apple is hard at work on an "iWatch," it will have to overcome battery issues bedeviling existing smartwatch makers.

This new crop of wrist devices has a lot more in common with smartphones than your old Timex. They have increasingly large displays, and can ferry over notifications and other data, acting as a second screen of sorts for your smartphone. For many of the latest models, that extra utility is not without a compromise: You've got to plug it in at the end of the day.

Charging a smartphone every day can be an annoyance, but … Read more

Nano Nails turns long fingernails into touch-screen stylii

LAS VEGAS--Long nails and touch screens don't get along very well. It can take some nimble finger acrobatics to get in touch with the display. Sri Vellanki of Tech Tips had already created an over-the-fingertip stylus. It was a natural step to then figure out how to integrate it into wearable fashion nails.

Nano Nails takes pretty much the same tip design as the Tech Tips and places it under the index fingernail. They will be available in either a full press-on nail or a nail tip. Vellanki expects them to sell for in packages of four or six for around $10. They could be put on by the wearer or applied at a salon.… Read more
