To put it lightly, something sensational happens upon feeding large concentrations of toxic gold chloride (also known as liquid gold) to the bacteria Cupriavidus metallidurans. After about a week's time, the bacterium creates a 24-karat gold nugget from the digested toxins.

"Microbial alchemy is what we're doing, transforming gold from something that has no value into a solid, precious metal that's valuable," said Kazem Kashefi, assistant professor of microbiology and molecular genetics at Michigan State University, where the research is taking place. … Read more

Researchers are developing a special process meant to replace the custom "paper" found in home pregnancy and other tests with plain old office paper -- a way of creating ultracheap methods of medical testing that could quickly diagnose pregnancy, malaria, diabetes, and more.

Ultimately, the idea is to replace the current standard, which relies on a membrane called nitrocellulose that sticks to molecules of interest, with cheap and ubiquitous paper that can stick to a whole fleet of chemicals, including DNA, antibodies, and sugars. And a University of Washington researcher wants to make the already cheap tests even … Read more

Even if you have a dashboard display showing what's behind your car when you back up, it's hard to be 100 percent sure you won't hit something. Or someone. That's why researchers at Japan's Keio University are working on a system that makes the back seat invisible, so to speak.

From the driver's perspective, the back of a car, in this case a Prius, is transparent, thus eliminating blind spots that could conceal hazards. The system is called the "see-through Prius" and it's being showcased this month at the 2012 Digital Content Expo in Tokyo. … Read more

Sometimes real science sounds more like science fiction. Just the phrase "bionic bees" sounds like something out of an old paperback.

But that's the goal of a new project from two U.K. universities, the University of Sheffield and the University of Sussex. Engineers from the schools are planning to scan the brains of bees and upload the data into flying robots with the hope that the machines will fly and act like the real thing.

The goal of the project is to create the first robots able to act on instinct. Researchers hope to implant a honey bee's sense of smell and sight into the flying machines, allowing the robots to act as autonomously as an insect rather than relying on preprogrammed instructions.… Read more

There's a hierarchy of "Star Trek" inventions we would like to see become reality. We already have voice-controlled computers and communicators in the form of smartphones. A working Holodeck is under development. Now, how about we get some impulse engines for our starships?

The University of Alabama in Huntsville's Aerophysics Research Center, NASA, Boeing, and Oak Ridge National Laboratory are collaborating on a project to produce nuclear fusion impulse rocket engines. It's no warp drive, but it would get us around the galaxy a lot quicker than current technologies.… Read more

While the Mars rover explores the Red Planet, a group of engineers submitted plans for a new out-of-this-world space mission: landing a boat on the Saturn moon Titan, which NASA, the European Space Agency, and Italian space agency ASI explored in depth over the last decade as part of the Cassini-Huygens mission.

Building on the successful 2005 landing of the Huygens probe on Titan, the new mission would aim to explore and collect data from the weird liquid methane makeup of the lakes found on the Saturn moon's surface. To explore these uncharted methane flows, engineers at the aerospace company Sener -- working in collaboration with Spain's Centro de Astrobiologia -- submitted a proposal last week to the European Planetary Science Congress for a Talise (Titan Lake In-situ Sampling Propelled Explorer) boat probe. … Read more

It turns out my obsessive daily viewing of eye-searingly adorable animal pictures online is actually an integral part of of my work productivity plan. I am indebted to some Japanese scientists for this revelation.

Researchers from Hiroshima University conducted a study to examine the effects of viewing cute images on task performance. Guess what? Looking at images of baby animals boosted performance, I'm thrilled to report.… Read more

The same researchers who last year developed "electronic tattoos" that bend and stretch on skin are now unveiling similar ultra-thin electronics, only these dissolve when their job is done.

Made of silicon, magnesium, and magnesium oxide and surrounded by a protective layer of silk, these "transient" electronics aren't built to last but rather to melt away and, in the process, reduce the need to pass or surgically remove tiny medical implants, researchers from Tufts and the University of Illinois write in the current issue of Science.

The researchers -- who have begun using their devices … Read more

It's part of the conventional wisdom now that machines are smarter than us, especially when it comes to specific challenges. Chess, for instance. World champion Garry Kasparov's defeat at the hands of IBM's Deep Blue computer in 1997 was a milestone in the story of artificial intelligence.

But did the machine merely psych him out? Statistician Nate Silver's new book "The Signal and The Noise: Why So Many Predictions Fail--But Some Don't" contains an anecdote about how a glitch in Deep Blue may have led Kasparov to overestimate the machine's smarts, according to The Washington Post.

Despite the machine's ability to evaluate 200 million moves per second, Kasparov easily won the first game of the match. In the 44th move, however, Deep Blue made an inexplicable play, moving a rook for no apparent purpose. … Read more
