Magnetic resonance imaging scanners produce images of the body using strong magnetic fields and radio waves to scan several images of the same area. By comparing these images, the scanner reveals even the most subtle abnormalities, such as young tumors.

Considering the nature of MRI scanners, it stands to reason that math might improve the time it takes to get and compare these images.

Electrical engineers and computer scientists at MIT's Research Laboratory of Electronics thought so, and they are publishing an algorithm they have devised that speeds scanning time threefold, reducing the amount of time someone would have … Read more

Over the last year there have been many malware attacks on Facebook users. These suspicious links and apps will infect the user's timeline, messages, and even their friends' "walls."

I don't know what kinds of things you see inside your head, but I do worry about it.

As for the things I see inside my head, well, if only I could show you. Actually, there are scientists at UC Berkeley who believe that they can show you.

I haven't let them into the house yet. But I can show you video of their work. I am grateful to the inner brains at Gizmodo, who first revealed this footage to me.

You will, naturally, be wondering whether the scientists created this footage, well, naturally.

In a way. They … Read more

The bottom line: Following on last year's big overhaul, Trend Micro makes a series of smaller changes to this year's Titanium security suites. AntiVirus Plus contains the core features, but it's really on a level with free competitors--and that's a hard sell.

Review: Last year was a headliner for Trend Micro's security suites. Overhauled with a lightweight interface and cloud-based detection, and rebranded as Trend Micro Titanium, the changes made the suite competitive again. The 2012 version builds on those improvements, so this year doesn't have a lot of big changes. Still, there are … Read more

The bottom line: The new Kaspersky Anti-Virus for 2012 introduces a dual cloud-and-local security system bundled under an overhauled interface that's both easy to use and familiar. The suite's scans aren't the fastest, but it definitely will protect you.

Review: Kaspersky Anti-Virus continues to provide users with a high level of protection that includes security tools not offered by many competitors. The 2012 version won't change the face of personal computer security, although this particular package of security options has attracted enough devotees to make it a best-selling program, both in and out of the security … Read more

HP held its annual Imaging and Printing Conference in Shanghai today, where the company announced plans to build out its business imaging division with 13 new printers designed to grease the workflow for small to midsize businesses. Along with hardware announcements, HP also unveiled new consumer features like ePrint Wireless Direct that lets users print with a smartphone without the need for an Internet connection; an advanced HP Printer Control app (PDF) for iOS devices; and a twist on HP ePrint called SocialID, which lets you assign a custom e-mail address that makes it easier for multiple users to print in the cloud.

One of the new product offerings you'll see soon is the HP LaserJet M275 (PDF), a multifunction printer with new TopShot Scanning that's essentially the reverse of 3D printing: the scanner bed can capture a 3D image of any object placed on the top-mounted tray.

This workhorse laser targets SMBs, so it can only hold up to 150 sheets of paper, but it also features ePrint and is fully compatible with Apple AirPrint so you can output images and documents directly from your iOS devices.… Read more

NirSoft's RegScanner is an enhanced Registry scan and search tool. When it finds the specified values, you can open them in RegEdit for modifying. RegScanner can also save and export .reg files that RegEdit can open. This simple but effective tool is portable freeware.

RegScanner opens with its Registry Scan Options dialog displayed, and we had to enter at least one character in the Find String field to proceed. We could select a Matching method from a drop-down list as well as choose to have the program look at Values, Data, Keys, and Unicode strings. We could also choose … Read more

I'm a longtime fan of PaperPort, which began life as a scanner/software combination and now exists solely as software. I've never found a better solution for organizing and preserving scanned documents, which is why PaperPort is among the few software products I'm actually willing to buy.

But $99.99? Ouch. That's the list price for the latest version. Fortunately, software developer Nuance has partnered with Laplink to offer PaperPort 14 (Windows) for $49.99. (Just to clarify, this is PaperPort Standard, not PaperPort Pro.)

That's for the download version, though you can get a … Read more
