Hydrogen Muscle Silences The Domestic Robot

From The New Scientist:

IF ROBOTS are ever going to be welcome in the home they will need to become a lot quieter. Building them with artificial muscles that run on hydrogen, instead of noisy compressed-air pumps or electric motors, could be the answer.

Kwang Kim, a materials engineer at the University of Nevada in Reno, came up with the idea after realising that hydrogen can be supplied silently by metal hydride compounds.

Quantcast Quantum Computers Could Tackle Enormous Equations

From U.S. News And World Report:

Trillions of variables may prove no match for envisioned systems.

A new algorithm may give quantum computers a new, practical job: quickly solving monster linear equations. Such problems are at the heart of complex processes such as image and video processing, genetic analyses and even Internet traffic control. The new work, published October 7 in Physical Review Letters, may dramatically expand the range of potential uses for quantum computers.

Video: Army’s Robot-Man Walks Like the Real Thing

From The Danger Room:

The makers of the eerily lifelike robotic mule have a new creation: a machine that walks around like a real human being. Boston Dynamics is building the “Petman” prototype for the U.S. Army, to test out protective clothing.

Crystals Hold Super Computer Key

From The BBC:

Tiny crystals could hold the key to creating computers with massive storage capacity, scientists believe.

The crystals could be used as storage devices for desktop computers capable of holding 100-times more data than current systems.

Scientists at the University of Edinburgh have been using low-energy lasers to make salt crystals in gel.

The development could allow users to store a terabyte of data in a space the size of a sugar cube within a decade.

This would be enough to hold the equivalent of 250,000 photographs or a million books.

New Software Could Smooth Supercomputing Speed Bumps

ONE SIZE DOESN'T FIT ALL: Researchers are increasingly turning to computers powered by a combination of graphics processing units (GPUs) and central processing units (CPUs), but they're looking for a better way to write software for these systems. © FOTOIE, VIA ISTOCKPHOTO.COM

From Scientific American:

Researchers turn to the Open Computing Language as a way to get graphics and general-purpose computer processors on the same page for more powerful number crunching

Supercomputers have long been an indispensable, albeit expensive, tool for researchers who need to make sense of vast amounts of data. One way that researchers have begun to make high-speed computing more powerful and also more affordable is to build systems that split up workloads among fast, highly parallel graphics processing units (GPUs) and general-purpose central processing units (CPUs).

Cheetah, Gecko And Spiders Inspire Robotic Designs

From Gadget Lab:

A cheetah can run faster than any other animal. A gecko’s feet can stick to almost any surface without using liquids or surface tension. And some roaches scurry at nearly 50 times their body length in one second, which, scaled up to human levels, can be around 200 miles an hour.

The wonders of the animal kingdom are not just for fans of National Geographic. Robotic designer Sangbae Kim, a professor at the Massachusetts Institute of Technology, is trying to understand how he can take some of the mechanisms animals use and replicate them in robots.

Fundamental Quantum Limit on Computing Speed of Any Information Processing System

The Next Big Future:

Physicists Lev Levitin and Tommaso Toffoli at Boston University in Massachusetts, have calculated a quantum speed limit on computing.

In a paper published in the journal Physical Review Letters, Levitin and Toffoli present an equation for the minimum sliver of time it takes for an elementary quantum operation to occur. This establishes the speed limit for all possible computers. Using their equation, Levitin and Toffoli calculated that, for every unit of energy, a perfect quantum computer spits out ten quadrillion more operations each second than today's fastest processors.

(A quadrillion is 10^15 or 1000 trillions)
