Gallium phosphide nanowires boost hydrogen yield in prototype solar fuel cell

By - July 20, 2015 2 Pictures

One of the most promising forms of artificial photosynthesis involves using solar energy to split liquid water to produce oxygen and hydrogen gas, which can be stored and used as a clean fuel. And one of the most promising semiconductor materials for such a task is gallium phosphide (GaP), which can convert sunlight into an electrical charge and also split water. Unfortunately, the material is expensive, but researchers have now used a processed form of gallium phosphide to create a prototype solar fuel cell that not only requires 10,000 times less of the precious material, but also boosts the hydrogen yield by a factor of 10.

Pill on a string pulls early signs of cancer

By - July 20, 2015 2 Pictures

As with every form of the deadly disease, early detection of oesophageal cancer is critical to recovery. The current approach of detecting the cancer through biopsy can be a little hit and miss, so the University of Cambridge's Professor Rebecca Fitzgerald and her team have developed what they claim to be a more accurate tool for early-diagnosis. Billed as "a pill on a string," the Cytosponge is designed to scrape off cells from the length of the oesophagus as it is yanked out after swallowing, offering up a much larger sample for inspection of cancer cells.

Massless particle discovery could radically accelerate electronics

By - July 20, 2015 3 Pictures
An exotic particle theorized more than 85 years ago has finally been discovered. Dubbed the "Weyl fermion", it is a strange but stable particle that has no mass, behaves as both matter and anti-matter inside a crystal, and is claimed to be able to create completely massless electrons. Scientists believe that this new particle may result in super-fast electronics and significant inroads into novel areas of quantum computing. Read More

Review: We flip the switch on MiPow's Playbulb Bluetooth LED bulbs

By - July 20, 2015 10 Pictures

The number of LED bulbs on the market has exploded in recent years, and with them has come a dizzying array of so-called smart bulbs featuring wireless connectivity and control, allowing users to set options for colors, schedules, and remote on/off functions. Although most of these look and perform similarly, consumer experience still varies as it generally comes down to the execution of the companion app. So how do the devices in MiPow’s Playbulb Studio compare? We lit up these LED bulbs to see how well they shine.

New cycling water bottle does away with the cage

Although most cyclists probably don't give much thought to their water bottle or bottle cage, the fact is that like just about anything else, those components can be lightened and simplified. That's just what British cycling design company Fabric has done, with its new Cageless water bottle.
