A new theory based on a simple but viable geologic model claims that over 80 percent of all commercial gold deposits were formed in a flash. Gold seams are formed when mineral-rich waters flow through networks of cracks in rocks some 5-30 km deep. But the exact mechanism through which the gold is deposited is [...]

Researchers have demonstrated for the first time the existence of a naturally occurring topological insulator – an exotic class of materials that possesses the unique ability to conduct electricity and the surface, but not on the inside. Previously, topological insulators have been studied and created in labs only, however now a mineral has been found [...]

Just a few days ago, we were telling you about the exciting new findings in lake Vostok – a new bacteria unlike anything else found so far retrieved from the lake sealed beneath 2 kilometers of ice for 1 million years. Now, the head of genetics laboratory at the Saint Petersburg Institute of Nuclear Physics [...]

If you were to lick the surface of Jupiter‘s icy moon Europa, you would actually be sampling a bit of the ocean beneath – at least that’s what a new paper by Mike Brown, an astronomer at the California Institute of Technology in Pasadena, Calif., and Kevin Hand from NASA’s Jet Propulsion Laboratory concludes. Their [...]

A team of international researchers from US and China have employed a novel method to link enzymes together and then encapsulate them in a polymer shell. This enables the enzymes to work sequentially in chemical reactions, just like in nature. To illustrate their enzyme batch, a group of mice were intoxicated with alcohol and then injected [...]

Researchers at University of Utah have recently demonstrated that it is indeed feasible to construct a topological insulator from organic compounds. Topological insulators are deemed very important by scientists because of their unique property of conducting electrons on their edges, while at the same time acting as an insulator on the inside. These capabilities make it [...]

Using 21st century nanotechnology, researchers have discovered a new mineral in samples from a meteorite discovered in Antarctica in 1969. The meteorite is 4.5 billion years old and originates from an asteroid orbiting between Mars and Jupiter. The new mineral has alluded scientists for some time since its discovery by a Japanese expedition team to Antarctica [...]

Scientists at  New York University have created a type of synthetic particles that can bind and assemble into clusters, similar to how flocks of birds or schools of fish organize themselves in complicated patterns. Self-assembling materials are far from being new, but what distinguishes this new research is that the particles eventually organize themselves in what [...]

Hydrogen is an extremely appealing energy source, despite the immense hurdles than come with storing it. Still fuel cells based on hydrogen are extremely useful, and a team of researchers at University at Buffalo may have found the fastest and most effective way of obtaining this element. Basically, it’s as easy as adding water. The scientists [...]

The cold, lifeless Vesta asteroid might be a lot more like our planet than astronomers believed – having a very active life in the early stages of the solar system evolution, a study of a Saharan meteorite shows. The planet that wasn’t Vesta might host a magmatic layer under its rocky exterior, allowing minerals to [...]
