This year is an historic one for nuclear power, with the first reactors winning U.S. government approval for construction since 1978. Some have seen the green lighting of two Westinghouse AP1000 reactors to be built in Georgia as the start of a revival of nuclear power in the West, but this may be a false dawn because of the problems besetting conventional reactors. It may be that when a new boom in nuclear power comes, it won't be led by giant gigawatt installations, but by batteries of small modular reactors (SMRs) with very different principles from those of previous generations. But though a technology of great diversity and potential, many obstacles stand in its path. Gizmag takes an in-depth look at the many forms of SMRs, their advantages, and the challenges they must overcome. Read More

The private spaceflight company SpaceX declared that 2012 would be the "Year of the Dragon" - a play on the current cycle of the Chinese calendar and the upcoming tests of SpaceX's Dragon space capsule. For a time, it seemed as if SpaceX was regretting that slogan. Dragon was chosen as one of five competitors for NASA's Commercial Orbital Transportation Services (COTS) contest to develop a cargo/passenger craft to service the International Space Station. The Dragon program had enjoyed considerable success and was scheduled to be the first private spacecraft to visit and, if all went well, dock with the International Space Station (ISS). Unfortunately, with the need for more testing of the Dragon capsule delaying the launch from its original February 7, 2012 date to late March or even into April, it looked as though the Year of the Dragon was starting a bit late.

This year marks the 60th anniversary of the Mercedes-Benz SL and to celebrate the occasion, Mercedes has completely restored the oldest surviving example to its original condition. Introduced to the press on 12 March 1952 on the autobahn between Stuttgart and Heilbronn, the prototype 300 SL (Super Lightweight) was powered by a 3-liter, six-cylinder in-line engine canted at 50 degrees with an overhead camshaft, three Solex twin carburetors and dry sump lubrication, which put out 170 bhp for a maximum speed of 143 mph (230 kph). Not bad for 1952. Read More

Russia's 13-ton (11.8-tonne) unmanned Phobos-Grunt interplanetary space probe that was launched from the Baikonur Cosmodrome in Kazakhstan on November 9, 2011 has reportedly burned up in the Earth's atmosphere. According to Russian Air and Space Defence Forces, the spacecraft was destroyed on Sunday, January 15th, 2012 at 1745 GMT as it made an uncontrolled re-entry and broke up 775 miles (1,250 km) west of Chile in the South Pacific.

The Amazon Kindle Touch is quite a remarkable little machine. In many ways, it can be seen as a halfway point between the Fourth Generation Kindle e-Reader and the Kindle Fire Tablet. However, it's not simply a glorified reader, nor is it a stripped down tablet. Rather, it is another way in which Amazon is building on its lead in the e-Reader market by optimizing the reader interface and user controls. With the Kindle Touch sure to find its way under many a tree this holiday season we put the device through its paces with a hands-on review. Read More

A new invention out of Norway promises to keep the skies of the world open. When a volcano in Iceland erupted in 2010, it spewed out invisible clouds of ash that spread across Europe–effectively shutting down all civilian and military air traffic, stranding millions of people and costing the world economy billions of dollars. Now, a new camera has been developed that will allow pilots to see and avoid volcanic dust clouds, making similar eruptions in the future much less disruptive. Read More

The ongoing search for Earth-like worlds has taken another promising step. On December 5, NASA announced the discovery of the planet most likely so far to sustain life outside of the Solar System. The exoplanet, given the undramatic name of Kepler 22b, was found by NASA's Kepler spacecraft as part of its mission to seek out Earth-type planets in our galaxy. Though Kepler 22b is not the first such planet to be detected in recent years, it is the first one orbiting a star similar to our Sun and at a distance where it is capable of possessing liquid water, which most scientists regard as essential for life to exist. Though this is a significant milestone, the question remains, how good a candidate for a second Earth is Kepler 22b? Could there be life there or is it a planetary blind alley? Read More

A duck pond may seem like the ideal place to spend a peaceful spring afternoon, but during mating season it can look like the scene of a gang attack. Though ducks as a species are famously monogamous, unattached drakes can be extremely aggressive. They attack any female in sight in a mating frenzy that often ends in the injury or death of the victim. This has resulted in the ducks developing ways to prevent unwanted matings and the drakes ways to overcome their defenses. Researchers in North America are developing a novel way to study this "evolutionary arms race" that uses high-speed cameras, force transducers and model duck oviducts made of glass. Read More

How much would you pay for a hamburger? How about US$345,000? No, it's not wrapped in edible gold leaf and held together with a skewer made out of a diamond stick pin that you get to keep. It's an ordinary burger that doesn't include the bun, lettuce, pickles or onions. It isn't even super-sized. This may seem like price gouging on a monumental scale, but it's actually the cost price for this particular burger. That's because even though it is a real hamburger made from real meat, it doesn't come from a cow at all. So where is all this heading? David Szondy investigates the past, present and future of lab-grown meat. Read More
