The Visiobike packs a lot of electronic features

As the recent Charged Up e-bike event showed us, the new generation of electric bikes is apparently here to stay. While many of them simply feature a motor that augments the rider's pedaling power, some really take the whole "electronics" thing and run (or roll) with it. The upcoming Visiobike is just such a machine. With a little help from the user's smartphone, it not only provides a power boost but also lets them navigate, deter thieves, see what's behind them via a video feed, and avoid having to shift gears.  Read More

A diagram of the new graphene production technique

Graphene is very thin, incredibly strong, electrically conductive and chemically inert, allowing it to be used in a wide range of technologies. It's also rather difficult to work with, however, limiting its practicality. That may be about to change, as researchers at MIT and the University of Michigan have devised a new method of large-scale graphene production.  Read More

The Scribble pen produces ink based on color samples of real-world objects

If you want to sample a color that you encounter in the real world and then reproduce it on your computer, you might already be interested in devices like the SwatchMate Cube or the NODE Chroma module. Sometimes, though, you might just want to do some freehand pen-and-ink drawing using such "captured colors." That's just what Scribble's upcoming Ink color picker pen is designed to let you do.  Read More

The Liam F1 Urban Wind Turbine is said to be considerably more efficient than most convent...

Although it's getting increasingly common to see solar panels on the roofs of homes, household wind turbines are still a fairly rare sight. If Rotterdam-based tech firm The Archimedes has its way, however, that will soon change. Today the company officially introduced its Liam F1 Urban Wind Turbine, which is said to have an energy yield that is "80 percent of the maximum that is theoretically feasible." That's quite the assertion, given that most conventional wind turbines average around 25 to 50 percent.  Read More

Diffuse optical tomography could offer a safer alternative to fMRI and PET scans (Photo: T...

When doctors want to monitor someone's brain activity, they generally use either functional magnetic resonance imaging (fMRI) or positron emission tomography (PET). One subjects the patient to strong magnetic fields, while the other involves radiation exposure. Scientists at Washington University in St. Louis, however, have recently had success using diffuse optical tomography (DOT). Although it may look kind of extreme, it basically just involves shining LEDs into the subject's head.  Read More

A vial of the clear hydrogel turns to a white semi-solid as it's heated to body temperatur...

In the field of regenerative medicine, one of the current areas of interest involves the use of scaffolding-like materials that a patient's own cells can be "seeded" onto. As the cells grow and populate the material, they gradually replace it, until all that remains is a solid piece of tissue or bone. Now, scientists at Houston's Rice University have taken that concept a step further, using a polymer that is liquid at room temperature, but that solidifies into a scaffold when injected into patients' bodies.  Read More

The 3D fruit printer uses spherification to create hybrid fruits, or to recreate existing ...

By now we're all quite used to seeing blended fruit juices such as banana-strawberry or apple-lime, but what about solid three-dimensional hybrid fruits that are made to order? Well, that's just what Cambridge, UK-based design company Dovetailed is promising, with its 3D fruit printer.  Read More

Scientists have created functioning human heart tissue that exhibits Barth syndrome  (Imag...

When we've previously heard about "organs on a chip," they've been miniature recreations of healthy organs. If they're being used for research into the treatment of health problems, however, then it only makes sense that those "organs" should have something wrong with them. With that in mind, a group of Harvard scientists have created the world's first lab-grown sample of functioning human heart tissue that has a cardiovascular disease.  Read More

An image captured using the new lens Night-vision security cameras could be getting a lot less costly, thanks to the discovery that their lenses can be made from silicon. Ordinarily, thermal infrared camera lenses are made from materials such as germanium and chalcogenide, which are much more expensive.  Read More

One of the three Lutra airboats used in the study

Although hippos may look slow and docile, they're actually very aggressive, killing more people every year than any other large African animal. So, it would follow that you wouldn't want to swim anywhere near them. That's why when researchers from Yale University and the Cary Institute of Ecosystem Studies wanted to study the effects of hippo dung on water quality in Kenya's Mara River, they sent in three autonomous air boats instead of people. To help those boats blend in, they were dressed up as crocodiles.  Read More
