Scientists unveil 'world's first practical artificial leaf'
Leaves – the kind that grow on trees – create energy from sunlight and water through the process of photosynthesis. For over a decade, scientists have been kicking around the idea of creating an "artificial leaf." Such a device would use sunlight to split water into hydrogen and oxygen, which could then be stored in a fuel cell and used to create electricity. A functioning artificial leaf has been created before, but was impractical due to the fact that it was made from expensive materials, and was highly unstable. Now, however, scientists are reporting that they have created a cost-effective, stable artificial leaf. Read More
It’s certainly an established fact that electricity can cause fires, but today a group of Harvard scientists presented their research on the use of electricity for fighting fires. In a presentation at the 241st National Meeting & Exposition of the American Chemical Society, Dr. Ludovico Cademartiri told of how they used a unique device to shoot beams of electricity at an open flame over one foot tall. Almost immediately, he said, the flame was extinguished. On a larger scale, such a system would minimize the amount of water that needed to be sprayed into burning buildings, both saving water and limiting water damage to those buildings. Read More
With the World Cup always held in the European off-season in June and July, the awarding of the 2022 World Cup to Qatar offers the prospect of players and spectators sweating through the hottest part of the year. Doha sees an average top temperature of 41 degrees Celsius (106°F) in these months with the possibility of top temperatures as high as 50°C (122°F). While shifting the World Cup to the cooler month of January has been mooted and since rejected, a team of engineering scientists from Qatar University (QU) have taken a more high-tech approach to solving the problem – they've reportedly developed a type of artificial "cloud" designed to float above the World Cup venues and provide fans and players with relief from the blazing sun.

iPad accessories are once again a hot topic following the release of the iPad 2. Apps and covers are usually the highest priority accessories, but the iPad's lack of ports means if you want to connect it to anything other than the included dock connector then you'll need an add-on solution. The 5-in-1 Connection Kit for iPad ups the connectivity capabilities of the iPad by providing the convenience of – you guessed it – five ports in a single dongle. Read More
Festo has added to its robotic menagerie with the creation of a robotic seagull that weighs just 450 g (15.87 oz) and boasts a wingspan of 1.96 m (6.4 ft). Dubbed the SmartBird, the ultralight flying robot was inspired by the herring gull and can take off, fly and land autonomously, without the help of any additional drive systems. Read More
Building a robot, it’s probably safe to assume, is a daunting project. It would doubtless be considerably easier if designers didn’t have to build everything from scratch, but could instead use pre-built modules. That’s where the iMobot comes into play. Designed by University of California, Davis alumnus Graham Ryland and professor of mechanical and aerospace engineering Harry Cheng, the modular iMobot is a small robot in its own right, but could also be used as part of a larger robotic system.

The U.S. Air Force’s goal of acquiring 50 percent of its domestic aviation fuel via alternative fuel blends derived from domestic sources by 2016 got a boost on Friday March 18, when an F-22 Raptor was successfully flown at speeds of up to Mach 1.5 on a 50/50 fuel blend of conventional petroleum-based JP-8 (Jet Propellant 8) and biofuel derived from an inedible plant called camelina. The flight capped off a series of ground and flight tests carried out earlier in the week for the Raptor using the biofuel blend to evaluate its suitability in the F-22 weapons system. Read More
Researchers from the University of Minnesota have announced a breakthrough in the quest to create a viable fuel alternative using greenhouse gases. The process uses two types of bacteria to create hydrocarbons from sunlight and carbon dioxide. Those hydrocarbons can in turn be made into fuel, which the scientists are calling "renewable petroleum." Read More
The first Orion crew module has begun testing at Lockheed Martin's Space Operations Simulation Center (SOSC) in Denver, Colorado. This 41,000 square foot research facility will test the ability of NASA's next-gen multipurpose exploration spacecraft to safely fly astronauts through the severe environments of deep space. Orion will be phased in as the sun sets on the Space Shuttle Program with the first orbital flight test planned for 2013 and first crewed mission by 2016. Read More
Eurotech launches Zypad WL1500 wearable computer
Around the time I was hoping to swap my Olivetti typewriter for one of those new-fangled Apple Macintosh things, Seiko also created the UC-2000 wrist computer. The images of the device docked onto a QWERTY keyboard strapped to someone's arm still raise a smile even now. That was decades ago, and the industry has moved forward at an incredible pace, but Eurotech's new Zypad WL1500 definitely has the look of the Seiko. Happily, the technology in the new Zypad is much more up-to-date. Eurotech says that it's faster and lighter than other members of its wearable range, and also benefits from a longer battery life and numerous communication options. Read More
