While city dwellers may be used to railway crossings marked with
flashing red lights, the easier-to-miss warnings at rural crossings
often just consist of a sign. That's because there's no easy way of
providing electricity to such isolated locations. While solar panels
could provide part of the solution, a team of engineering students and
faculty at the University of Nebraska-Lincoln believe that photovoltaics
alone can't consistently provide enough power. Instead, they devised
several systems that harness power from the rails themselves.
Amplifying light a few hundred times with magnifying lenses is easy.
Amplifying light by altering the resonant properties of light itself is a much
more difficult proposition. However, if recent research by engineers at the
University of Wisconsin-Madison engineers is anything to go by, the effort is
well worth it: They claim to have constructed a nanoscale device that can emit
light as powerfully as an object more than 10,000 times its size.
While many people may like the "pop-in-your-mouth" texture of caviar,
not everyone likes the taste ... or the price. That's why Montreal
entrepreneur Naor Cohen created the grandly-named Imperial
Spherificator. It takes a liquid of your choice, and converts it into
fish egg-like pearls. Sriracha caviar, anyone?
Most "new" products we see are really just minor evolutions of gadgets that have been around for years. But here's one that's completely unlike anything we've used before. Meet Thync, a wearable that zaps your brain to change your mood – like a drug that replaces chemicals with technology.
Thanks to the highly popular TV show Breaking Bad, new German e-bike company HNF Heisenberg immediately grabs your attention with its science-gone-meth-mad name. It is sure to hold that attention with the XF1, an innovative, high-performance electric mountain bike. The new bike uses a special swing arm developed by BMW i to lay claim to being the world's first mid-motor, belt-driven full-suspension e-bike.
Portable test kits represent an advance in disease diagnosis, as their
ready availability increases chances of earlier detection and treatment.
This type of technology is constantly evolving, and sometimes
inspiration can come from surprising sources. Such is the case with
research carried out by a Swiss team, which has borrowed from the
mechanics behind the firefly's glow to develop a sensitive molecule
Here's a neat idea from a young designer based in Bath, England. The BATH °C Thermo Colour Map offers a new take on the tourist map by highlighting certain areas of the city that are most suitable to visit, depending on the weather.
We already know that cardboard isn't just for packaging, but US company Ernest Packaging Solutions recently pushed the envelope to create a cardboard skateboard deck. The deck was put through its paces by pro-skating legend Tony Hawk.
The Garmin vivoactive fitness tracker is a smart(ish) watch which combines all-day activity and sleep tracking along with more detailed exercise monitoring thanks to built-in GPS capabilities. Gizmag recently spent a few weeks putting the device through its paces, as it put us through ours, to see what it can do and who it is best suited for.
Motorola usually launches new versions of the mid-range Moto G and top-end Moto X in September, but this year we've been treated to the new handsets a month or so early – and there's a third model to weigh up too. The Lenovo-owned company announced the 2015 editions in a global press event streamed live on its website.
