Gregory Zielinski with his Nuseti prototype

Much as mountain bike technology has advanced since the days of friction shifting and elastomer shocks, most MTBs are still equipped with dangling, fragile rear derailleurs and dirty chains. Switching to a belt drive or a hub transmission are a couple of options, but Polish mountain biking medalist Gregory Zielinski has created another. His Nuseti bike features what he calls the Inner Drive System (IDS) – a 16-speed planetary gearbox that's incorporated into the bottom bracket, and a chain that's enclosed within the frame.  Read More

TabiMouse lets your iPhone serve as a trackpad mouse for a PC-emulating iPad You've got an iPhone and an iPad, but you don't have a mouse to use with the iPad ... or do you? Actually, Tabitop's new TabiMouse app converts an iPhone into a Bluetooth iPad-friendly mouse. The only catch is, you have to be willing to use your iPad as a PC.  Read More

The Restoring Active Memory project is aimed at helping brain-injured veterans and civilia...

Earlier this year, we heard about how DARPA (the Defense Advanced Research Projects Agency) was setting up its new Biological Technologies Office. The goal of that division is to "merge biology, engineering, and computer science to harness the power of natural systems for national security." This week, the agency released details of one of the office's key projects, called Restoring Active Memory. It's aimed at using implantable "neuroprosthetics" to help army veterans and other people recover from memory deficits caused by brain injury or disease.  Read More

TransWall displays interactive content on both of its faces

You've probably seen TV shows in which groups of characters – usually forensic investigators – view data on large transparent touchscreen displays. Well, researchers at the Korea Advanced Institute of Science and Technology (KAIST) have taken that concept a step further. Their TransWall is not only transparent, but it can also receive input and display content on either side of its screen, plus it's capable of haptic feedback.  Read More

Rocketskates are worn over regular shoes

Back in 2010, we first heard about inventor Peter Treadway's concept for powered wheeled footwear that also allowed the user to walk under their own power when desired. Two years later, the concept was the subject of a Kickstarter campaign, in the form of spnKiX motorized skates. Now, Treadway has returned to Kickstarter with an improved take on the original idea, known as Acton R Rocketskates.  Read More

The DJI Ronin uses the company's ZenMuse system, first designed for aerial videography

DJI Innovations is a company that's best-known for its consumer and professional-grade multicopters, including the popular Phantom line of quadcopters. One of its products, the ZenMuse, is a motorized gimbal designed to keep cameras steady and level when mounted beneath such aircraft. Now, that same tech is available for hand-held video cameras, in the form of the Ronin stabilizing rig.  Read More

The UCR NOx-Out device replaces the muffler on an existing gas mower

Gas-powered lawnmowers are notorious polluters. According to the US Environmental Protection Agency, running a new gas mower for one hour produces as much air pollution as would be generated by 11 typical automobiles being driven for the same amount of time. Switching to an electric or reel mower is certainly one option, but for those applications where it's gotta be gasoline, a team of engineering students from the University of California, Riverside are developing another: an attachment that they claim reduces noxious emissions by over 90 percent.  Read More

The EcoDrain uses outgoing hot water to heat incoming cold water

Generally-speaking, when there's something that we're trying to conserve, we don't just put it down the drain. For those of us who are trying to save power, however, that's just what happens when we let hot water from our showers or baths run straight into the sewer. The EcoDrain is made to address that problem, via a unique design that allows outgoing hot water to warm up incoming cold water.  Read More

A mouse's small intestine, as made visible using nanojuice

When someone suffers from a gastrointestinal disorder such as celiac disease, Crohn's disease or irritable bowel syndrome, it's standard practice for doctors to take a look at the state of their small intestine. This is typically done by having them drink a rather unpleasant-tasting barium solution, and then submitting to x-rays, an MRI or ultrasound. According to scientists at New York's University at Buffalo, however, all of those imaging techniques have serious shortcomings. Their proposed solution? A stiff drink of nanojuice.  Read More

The Backtracker's front module alerts riders via an LED display

Cycling on the highway can definitely be a risky business. If riders are distracted or have the wind in their ears, vehicles rapidly approaching from behind can be almost right on top of them before being noticed. Gadgets such as mirrors and rear-view cameras can help, although riders still have to think to check them. The Backtracker, however, uses a radar signal to automatically alert cyclists whenever a car is closing in on them.  Read More
