Some say that your cellphone can give you cancer, even though the jury is still out, but this device from researchers at Harvard is a smartphone compatible gadget that helps detect cancer in its early stages. Extracting large tissue samples is painful, so researchers at Harvard Medical are now testing a prototype handheld device attached to a smartphone that takes very small tissue samples and tests them for signs of cancer within half an hour.

That is amazingly fast. It is in the prototype stage right now, so don’t expect your doctor to have one just yet. But when they do, we can catch the disease faster and treat it more effectively.

You can walk against cancer, run against cancer, crawl against cancer, or buy some pink gadgets. Personally, I can’t see that ever beating cancer, though it does put your money in some deep pockets to be mis-managed and pillaged. But if you are not as jaded as I, you might want to join the good fight and get yourself these pink OtterBox cases.

They support the Avon Breast Cancer Crusade and the 2010 Avon Walk for Breast Cancer by offering a limited edition, pink and white Commuter Series for the BlackBerry called “Strength” cases. The following BlackBerry’s will be supported: BlackBerry Curve 8500/9300 series, Pearl 3G and Bold 9700 series.

The debate continues as to whether or not cell phones can harm us, but one state may be ready take the next step in warning consumers about the dangers. If she has her way, a Maine legislator wants to make the state the first to require cell phones to carry warnings that they can cause brain cancer, even though there is no consensus among scientists that they do.

Cell phones carry these warnings in some countries, but right now no U.S. states require them. A similar effort is underway in San Francisco, where Mayor Gavin Newsom would like his city to be the nation’s first to require such warnings. These measures seem premature, given the fact that there is no hard data to support the claims.

The Tour de France is currently underway and Lance Armstrong is apparently returning to help promote his Livestrong campaign and raise cancer awareness. So Livestrong and Nike have teamed up to create the Chalkbot, a robotic chalk painter that will print messages along the path of the Tour de France.

If you want your own message printed just text ‘LIVESTRONG’ followed by your chalk message to 36453. They hope to print more than 100,000 messages over the course of the entire race. We like stories like this where robots are helping worthy causes instead of plotting our demise.
