3D printing has captured the imaginations of just about anyone who knows what it is -- even NASA, apparently.

The space agency is using a similar technology to create precise metal parts for its next heavy-lift rocket, which it hopes will eventually help take humans to Mars.

The method is called selective laser melting, or SLM, but it's not quite the same as printing up a sweet "Star Wars" chess set out of extruded plastic. It's more of a cross between 3D printing and some high-end, defense-grade awesome tech.… Read more

A test version of Adobe Systems' Lightroom 4.3 has added partial support for Apple's Retina displays and other high-resolution screens.

The Lightroom 4.3 release candidate, available on Adobe Labs, shows photos in the develop module so that one pixel in the original photo occupies one pixel on the screen. That means a much sharper and detailed image than with the older Lightroom 4.2, which scales images so that one pixel on the photo occupies four pixels on the screen.

I was worried that Adobe would Retina support for Lightroom 5, which presumably will be a paid … Read more

It has been almost 40 years since the Apollo 17 mission last landed a man on the moon. It may not take anywhere near that long before we send astronauts back to the moon's neighborhood.

Space.com reports that NASA is seriously looking at sending out a new manned moon mission with the purpose of creating a manned outpost beyond the far side of moon and eventually visiting an asteroid in 2025. This may not physically land a human on the moon, but it would establish a deep space outpost as a base for research and missions.… Read more

It's not the locker room type of storage we're talking about here. Instead it's something much more important and often underrated: the place where information is stored.

When it comes to computer storage, judging from many questions friends and readers send me, there's quite a bit of confusion among general users as to what it actually is. And it's not your fault; digital storage can be as messy as my desk. This is the reason for … Read more

A new poll suggests that Windows 8 may be hampered by scant consumer interest.

Microsoft bills Windows 8 -- a world away from the familiar surroundings of Windows 7 -- as a "reimagining" of the PC operating system. It may indeed be that, considering Windows 8's touch capabilities and app ecosphere. But whether consumers will take to the new OS remains to be seen.

A survey of nearly 1,200 U.S. adults by the Associated Press and market researcher GfK found that 52 percent of respondents had not heard of Windows 8 and that 61 percent … Read more

Downloading files, installing and uninstalling software, and other daily activities create messes that take up space and impact performance. Wise Disk Cleaner is a housekeeper of sorts, making sure that things are tidy and functioning at their best.

Wise Disk Cleaner has an attractive, well-organized interface that arranges its features in four tabs. The Common Cleaner is a quick scan that gets rid of the most obvious junk, while the Advanced Cleaner digs a little more deeply to find more space-wasters. The Slimming System feature gets rid of unneeded Windows files, such as music samples and Windows update uninstallation files. … Read more

Microsoft officially launched Windows 8 today, and with it comes a choice for those who use its predecessors: do I stay, or do I go?

My Crave colleague Eric Mack touches on the subject in an opinion piece today titled "The Windows 8 question: To adopt early or not?" Eric owns a perfectly capable Windows 7 laptop and would rather wait for a Surface tablet with Windows 8 Pro to debut before considering new hardware.

Personally, I feel a slight temptation to upgrade to Windows 8. In his review of Microsoft's Surface, CNET Senior Editor Eric Franklin praises Metro -- the primary interface of Windows 8 -- saying it's "innovative, elegant, powerful, and versatile," the last set of words I would use to describe my cluttered Windows 7 desktop. Maybe a new layout would feel like a breath of fresh air. … Read more

A U.K. design firm put Windows 8 under the microscope recently, and users reported some issues with handling the operating system.

The firm in question, Foolproof, had 14 "typical users" try out Windows 8 for the first time to see how they fared using the new-look operating system. This tiny group reportedly consisted of regular Windows users, so they supposedly weren't coming to the Microsoft universe cold.

But Microsoft's new user interface, which largely consists of a series of tiles, ditching the traditional look and feel of Windows, "comes with a huge learning overhead." Foolproof's relatively small number of testers made several observations, including:… Read more

Do you dream of traveling to the stars? Unless you've got $20 million and change for a ticket to orbit, Vito Technology's Solar Walk is about as close as you're going to get.

This jaw-dropping iOS app provides a wholly interactive 3D model of our solar system, one that's had me hooked for days. It's the kind of thing you can imagine a science teacher using in the classroom of the future -- except that we don't have to wait.

Solar Walk works like an outer-space edition of Google Earth, letting you rotate, zoom, … Read more
