Unique droplet network 3D printer produces synthetic tissues
While the prospect of 3D printers pumping out biological tissues and replacement organs has many justifiably excited, researchers at Oxford University have gone in a slightly different direction with the creation of a custom 3D printer capable of producing synthetic materials that have some of the properties of living tissues. Rather than being intended for supplying spare parts for damaged replicants, the new materials could be used for drug delivery or replacing or interfacing with damaged tissues inside the human body.

3D printing has already gone well beyond the bounds of model making, and biotechnology is one of the new frontiers where the technology is set to make a huge impact. Nanoscribe GmbH, a spin-off of the Karlsruhe Institute of Technology (KIT), is pushing the boundaries of this space with the release of what's claimed to be the world’s fastest and highest resolution commercially available 3D printer of micro- and nanostructures – the Photonic Professional GT.

Highly prized by perfume makers, ambergris is a natural material that fetches thousands of dollars per pound. The high price tag is due to the material's rarity, which is a result of its source – the digestive system of sperm whales, from which it is expelled to float around the ocean and has led to it being dubbed "floating gold." While its cost and the endangered status of the sperm whale has caused many perfume manufacturers to turn to synthetic alternatives, the most popular of these is laborious to produce. Now a team of researchers has developed a method to sustainably produce large quantities of an ambergris alternative. Read More
Revealed: World Technology Network's innovators of 2012
The World Technology Network summoned leading thinkers to New York's TIME Conference Center on Monday and Tuesday to announce the winners of its 2012 World Technology Summit & Awards. The awards showcase the work of innovators across a diverse array of industry sectors and scientific fields. Gizmag reveals the list of winners, which includes no shortage of familiar faces.

Art and science combine to turn gold chloride into nuggets
For centuries, the world's great thinkers were consumed by the search for the mythical Philosopher's Stone. Franciscan friar Roger Bacon is said to have penned a formula for its creation in the 13th century, legend would have us believe that German friar Albertus Magnus actually found a substance capable of transmuting base metals into gold or silver, and English scientist and mathematician Isaac Newton was a known devotee of the magnum opus. Researchers at Michigan State University (MSU) have put a microbial spin on the ancient quest by creating a bioreactor that forces bacteria to transform a toxic liquid that, as team member Kazem Kashefi says, "has no value into a solid, precious metal that’s valuable."

Scientists at the Massachusetts Institute of Technology (MIT) have succeeded in genetically altering Ralstonia eutropha soil bacteria in such a way that they are able to convert carbon into isobutanol, an alcohol that can be blended with or even substituted for gasoline. It is hoped that once developed further, this technology could help reduce our reliance on fossil fuels, and lessen the amount of carbon dioxide released into the atmosphere by smoke stacks.

Having roamed the seas for at least 500 million years and holding the title of the oldest multi-organ animal on the planet, jellyfish have certainly stood the test of time. So it’s probably not surprising to see various research groups looking to the gelatinous, umbrella-shaped animals for inspiration in a number of areas, including the development of ocean-going robots. Now researchers at Harvard University and the California Institute of Technology (Caltech) looking to gain a better understanding of how biological pumps such as the heart work, have created an artificial jellyfish from rat heart muscle and silicon.

A strong and highly selective instant adhesive inspired by the bacterium Streptococcus pyogenes has been developed by Oxford University researchers. S. pyogenes is a common resident of human throats that is normally kept in check by the body's defenses, but when it gets out of control it can cause diseases ranging from strep throat to toxic shock syndrome or flesh-eating disease. By engineering a protein that is central to S. pyogenes' infectious arsenal, the researchers have developed a new superglue that can't be matched for sticking molecules together and not letting go.
