People in the Boston area, and those close to people possibly affected by today's explosions there, are understandably worried about their ability to find or communicate with each other. As a result, a number of organizations have created resources to help. This is a collection of several of them.

Tracking friends and family

For those trying to track down people they worry might have been victims of the explosions, there are at least two people finders. First is one set up by Google, and a second comes from the Red Cross. A third service is a list of runners who checked in … Read more

As news spread of the blasts at the finish line of the Boston Marathon on Monday afternoon, people in the area reported that phone lines were down and cell phone calls could not get through. However, smartphones enabled some to send text messages and update social media accounts.

People took to social media sites like Twitter and Instagram to notify loved ones that they were OK. Others were using Twitter as a tool to reach out and ask those in the area to post updates.

Law enforcement officials could have something very different on their hands as they investigate the dual bomb blasts that struck the Boston Marathon finish line today: a potential abundance of photo and video evidence from the public.

Government surveillance, while growing, still misses more than it catches. But events with thousands of spectators offer the potential for a detailed crowdsourced record of what happened.

This public panopticon is changing how we see the world. February's Russian meteor was captured by many dash-cams mounted in Russian cars, but in this case the event is of profound interest to law enforcement … Read more

Shortly after at least two bombs exploded near the Boston Marathon finish line today, reportedly killing at least two people and injuring dozens, cell phone service in the heart of the city was severely disrupted.

An Associated Press report initially claimed, citing an anonymous law enforcement official, that "cellphone service has been shut down in the Boston area to prevent any potential remote detonations of explosives." But AP reporter Peter Svensson said on Twitter at 2:45 p.m. PT that "cellphone problems in Boston are not due to an intentional shutdown" and the wire service was publishing an updated story. AP subsequently reported that service was operating in the Boston area, though cell traffic was heavy in the aftermath of the bombings. … Read more

Perfect for outdoors enthusiasts, Google's My Tracks app records your path, speed, distance, and even elevation while you walk, run, bike, or do anything else that a GPS signal can follow.

To get started, just open up My Tracks and hit the record button at the top of the screen. From there, so long as you have a strong GPS signal, My Tracks will plot … Read more

Claire Lomas suffered a T4 spinal injury in a 2007 horse riding accident that left her paralyzed from the chest down. In 2012, she completed the London Marathon. What happened in between was the development of a robotic suit that let her tackle the challenge on her own two legs.

It took 17 days for the 32-year-old resident of Leicestershire, England, to cross the finish line. Her motivation for the marathon was to raise funds for spinal cord injury research. So far, she has raised nearly $200,000.

The robotic ReWalk suit, one of several such devices, is made by Israeli company Argo Medical Technologies. It's a powered exoskeleton full of motion sensors, rechargeable batteries, and a computer system that allows the walker to control the suit.

ReWalk lets users stand, walk, and even climb and descend stairs. Crutches are used for stability (Lomas still has use of her arms). … Read more

What more can one say about Tetris? The megapopular classic '80s action puzzle game from Russian programmer Alexey Pajitnov is now available for the iPhone, featuring everything you loved about the original, and some added bonuses to keep the game interesting. The game is crystal-clear with Retina Display support and the simple interface requires only swipes and taps on the screen to move, rotate, and drop pieces on the board. Sometimes the tap-to-rotate and swipe-to-move method can be a little frustrating (it's easy to make mistakes), but we were mostly able to enjoy the classic game on our iPhone … Read more

If you're walking the streets of Houston this week and happen upon a group of very strange, oddly-shaped vehicles, there's a good chance you'll have wandered into the future of efficient cars.

From April 14 to 17, Shell is hosting the Eco-Marathon, a competition that tasks high school and college students with designing, building, and testing highly energy-efficient vehicles.

And the goal that every team that entered the Eco-Marathon is out to achieve this year? To beat last year's winning team, from Laval University in Quebec, Canada, which built a car that gets 2,487.5 … Read more
