Siemens' smart C-Walker guides the cognitively impaired

By - January 8, 2014 6 Pictures
The C-Walker is a high-tech walking device that aims to safely guide people with cognitive impairments through public spaces like airports and shopping centers, reducing their reliance on visual signboards and avoiding obstacles in their way. Using onboard sensors, this "cognitive navigation prosthesis" monitors its environment in real time to figure out a path that poses little risk, actively re-planning it when it encounters problems like wet floors, or people dashing about. Aside from aiding senior citizens, the technology is expected to come in handy in factory settings, helping workers avoid danger zones and accidental collisions with machines. Read More

A good book can change your life ... and your brain

By - January 5, 2014 2 Pictures
Stories, whether fact or fiction, are at the heart of human culture. A strong narrative can resonate with your personality and experiences, and help set a framework for your future. "That book changed my life" is a cherished maxim. So can a book change your brain too? A recent study led by Emory University's Gregory Berns has demonstrated that reading a novel produces physical changes in the brain similar to those that would result from living as one or more of the characters.

Frankenstein's simulated worm is alive?

By - January 3, 2014 4 Pictures
The OpenWorm project is aimed at creating the first artificial lifeform – a bottom-up computer model of a millimeter-sized nemotode, one of the simplest known multicellular organisms. In an important step forward, OpenWorm researchers have completed the simulation of the nematode's 302 neurons and 95 muscle cells and their worm is wriggling around in fine form. Read More

Michigan Tech physicists search for time travelers on Twitter

By - January 2, 2014 1 Picture
At this juncture in time, humanity does not know how to travel into the past, or even if such a concept has any meaning. So if you are an astrophysicist who wants to uncover evidence of time travel, what do you do? If you're Michigan Technological University astrophysics professor Robert Nemeroff and his PhD student Teresa Wilson, you look for time travelers on Twitter. Read More

Algae to crude oil: Million-year natural process takes minutes in the lab

By - December 24, 2013 5 Pictures
Engineers at the US Department of Energy’s Pacific Northwest National Laboratory (PNNL) have created a continuous process that produces useful crude oil minutes after harvested algae is introduced. This new process does not require drying out the algae, which grows in water, saving time and energy that would be otherwise wasted. The final product can be refined into aviation fuel, diesel, or gasoline. Read More

Scientists grow liquid crystal "flowers" to use as lenses

By - December 24, 2013 6 Pictures
Scientists at the University of Pennsylvania have grown liquid crystal flowers, making it possible to create lenses as complex as the compound eye of a dragonfly. When perfected, the technology could allow the growth of lenses on curved surfaces, and structures to be assembled out of liquid crystals to build new materials, smart surfaces, microlens arrays and advanced sensors.

Plant-based magnetic microswimmers to deliver drugs more precisely

By - December 23, 2013 2 Pictures
If you remember the 1966 science fiction film Fantastic Voyage, you'll recall how miniaturized government agents traveled through blood vessels in a tiny submarine, in their attempt remove a blood clot from a scientist's brain. Synthetic nanomotors that can do the same job have been the subject of numerous research efforts and now University of California, San Diego (UCSD) researchers report that they've created powerful biodegradable "microswimmers" that can deliver drugs more precisely, derived from common plants like passion fruit and wild banana.
