A new microchip-based device that can discover and analyze circulating tumor cells, or CTCs, in a blood sample, could prove to be a valuable new tool for fighting cancer. CTCs, which originate in solid tumors, can be found in the bloodstream, but not too often. For every billion normal cells, you might only find one CTC.
Now scientists at Massachusetts General Hospital, reporting in the journal Nature, say they've developed a nanofluidics-based device that can monitor how a patient is responding to a given cancer treatment by studying these tiny indicator cells. The technology may also help with early detection.—Gregory Mone
Andrew Rasiej and Micah Sifry created techpresident.com to answer an important question this election season: Do Facebook friends equal votes?

During the last presidential election, Andrew Rasiej was busy advising Howard Dean on his campaign´s use of technology. Micah Sifry was a journalist covering the intersection of politics and the Internet for The Nation. This time around, the two are running the first-ever Web site that tracks how the candidates are using-and just as often, failing to use-technology to bolster their campaigns.

Think the iPhones 3.5-inch screen is big? How about a handheld with a 100-inch screen? Thats the promise of Microvisions PicoP laser projector.
By bouncing pulse of red, green, and blue laser light of a vibrating mirror, the PicoP can paint WVGA (848x480-pixel) images up to 100-inches diagonal in a dark room—or about 12 inches under bright lights—on a wall, tabletop or any other surface.
Measuring a scant 0.26 by 0.79 by 1.57 inches, the PicoP is about the size of the original cellphone cameras, and Microvision hopes to make it just as ubiquitous in cell phones and other handhelds.
For starters, though, Microvision will bundle the PicoP with a battery in a separate handheld device, about the size of an iPod—called the SHOW, a prototype that the company debuted today. Microvision says its already inked deals with companies that will sell the SHOW under their own brands before years end. Prices arent set, but spokesman Matt Nichols says they could be made and sold profitably for under $500.
Microvision appears to be leading the slow-paced race with Light Blue Optics and Texas Instruments to bring the first micro projectors to market. Like Microvision, TI did show an early prototype laser projector at last years Consumer Electronics Show. But TI has since decided to switch from lasers to light-emitting diodes for its Pico Projector, and it is not expected to show anything new at the 2008 CES next week.—Sean Captain

2007 was a notable year for exploration of the Red Planet, but this year should prove to be just as exciting. Discovery News has a nice round-up of what to expect. Spirit and Opportunity, the twin rovers, are still hard at work, and three orbiters are still studying the planet from up high.
A new probe, Phoenix, is also slated to land on Mars' north pole on May 25. Researchers are hoping the lander will study samples of water ice and help them find new clues about the planet's history. Phoenix will look for evidence of organic molecules, too. And if you just can't wait until May, you can track the spacecraft's journey to Mars here.—Gregory Mone

The Pew Internet & American Life Project released a study this past weekend that details how we use the Internet. Apparently, 58 percent of Americans go online when looking for information about health, school, taxes, jobs, voting, legal issues, immigration and other key issues. That may seem low, but relative to other potential sources, it's surprisingly high. Only 36 percent, for example, looked to traditional media such as magazines and newspapers, and 45 percent turned to friends and family. Furthermore, only 13 percent went to the library. Surprisingly, though, 40 percent of respondents in the 18 to 30 age bracket known as Generation Y said they'd go to those book-filled buildings for information. Not necessarily for the stacks, though. 65 percent of them said they'd go to libraries because they have computers.—Gregory Mone

In May 2007, we published a project on Instructables that showed how to assemble a potentially useful tablet PC. Why was this project only a potential success? We couldnt get the Fujitsu Stylistic 1000 to boot. All of that has changed and now we can boot the Tablet PC in DOS, Windows 95, and DSL Linux. The secret element that made this doorstop into a viable Tablet PC was a Windows tool called HP USB Disk Storage Format Tool V. 2.1.8. At the link, a Texan named Nox will supply all of the needed know-how for using this utility, as well as downloads for both HP USB Disk Storage Format Tool and a collection of boot files. Now dont get too excited, these dated tablet PCs only worked really well when they were booted into DOS. So we converted ours into a dedicated DOS game machine. Skip the stylus and use an old salvaged PS/2 keyboard. Also, drop the battery and pick up a power supply. These two mods to our original project will shave about $135 off the projects price tag. Not bad for around $120.—Dave Prochnow

JKKMobile is expanding his bag of Eee PC tricks. The newest addition to his repertoire is grafting a 3G modem complete with SIM card inside his ASUS Eee PC. Both video and a set of sorta step-by-step images will help guide you through the process. Have you hacked your Eee PC, yet? If so, please post your project in our comments section.—Dave Prochnow
Large-scale photgraphs symbolize the environmental excesses and inequities of consumer culture

This image depicts eight million toothpicks. According to Seattle artist Chris Jordan, that's how many trees are harvested in the U.S. each month to make paper for mail-order catalogs.
The images are part of Running the Numbers: An American Self-Portrait, a series depicting the excesses and inequities of contemporary American culture. Each image portrays a specific quantity of something, such as the number of American children without health insurance, or the number of disposable batteries produced every 15 minutes. Many of the images are mosaics of common objects.
