The marriage of high performance optics with microfluidics could prove the perfect match for making lab-on-a-chip technologies more practical. Microfluidics, the ability to manipulate tiny volumes of liquid, is at the heart of many lab-on-a-chip devices. Such platforms can automatically mix and filter chemicals, making them ideal for disease detection and environmental sensing. The performance of these devices, however, is typically inferior to larger scale laboratory equipment. While lab-on-a-chip systems can deliver and manipulate millions of liquid drops, there is not an equally scalable and efficient way to detect the activity, such as biological reactions, within the drops.

The aptly-named StickyBot is a gecko-like robot that can climb smooth surfaces using its feet, which are covered in small, dry rubbery hairs (called setae on the gecko) which provide enough surface tension for dry adhesion. While the original StickyBot has 4 toes per foot, the team at Stanford has created the SB2 which has only 2 toes per foot while still retaining its climbing ability.

The Care-O-bot® research initiative aims at making Care-O-bot® 3 available as high-tech research platform. The main objectives to reach this goal are to provide a common open source repository for the hardware platform provide simulation models of hardware components provide remote access to the Care-O-bot® 3 hardware platform

You may think that all of those crazy robot competitions that we like to cover are just fun and games, but there’s a serious side. Really, there is. For reals. Mindful of this, ROBO-ONE held the second annual Humanoid Helper Project last weekend, where teleoperated human-sized robots completed (or attempted to complete) three seemingly simple tasks, including pouring liquid from a plastic bottle into a cup, carrying ping-pong balls on a tray, and a 30 minute endurance race. I don’t know about you, but the last two would be a bit of a challenge for me, and they certainly were for the robots:

Piotr Zalewa has created a really great playground, jsFiddle, for testing sample code and playing with the Web. With an area for the holy trinity of the Web (HTML, CSS, JS) and an output region, you can get right to hacking. It goes beyond this though. You can also add resources, an Ajax echo backend, and auto load from a slew of JavaScript frameworks. You can also check out the examples and see great stuff such as Processing in action. And the finishing touch, share and embed. Piotr wrote all of this using CodeMirror and MooTools. Nice! Having worked on Bespin, and developed a playground like this (looking forward to show a new mobile one soon!) I appreciate the work!

Image stabilization remains a major challenge for video cameras, from high-end cinema and broadcast units down through consumer camcorders. Although a variety of technologies now exist to stabilize images, they are typically complex and come at a steep price, making them impractical for most applications. Yet some end users often swallow that cost simply because the alternative can be more expensive. For example, an intricate shot on a movie set could cost hundreds of thousands of dollars to recreate if the first take can't be used because it turned out to be too shaky. Of course, not every end user can justify that expense. So what's needed is a solution that can scale from the low end to the high end, with no trade-offs along the way in terms of price and performance. That's a tall order, but meeting it creates a huge market opportunity. For example, besides applications such as broadcast, cinema and consumer cameras, the technology also could be used in verticals such as government and security.

It seems robots are getting into acting more and more these days, which makes sense given acting is nothing more than a simulation of real feelings and situations.  Last year we took a look at a few examples, but a UK-based company has been at it since 2005; their latest being the RoboThespian RT3.  Developed by Engineered Arts Ltd, the robot is actuated primarily by Festo air muscles and dc servo motors.  You can see him in person at Pittsburgh’s Carnegie Science Center, where he was nicknamed Andy (short for android) as part of their permanent roboworld exhibit.

Supporting the Wind River Systems VxWorks operating system on Intel architecture is valuable for customers who would like to preserve their application software and evaluate other architectures for comparison purposes or for architecture conversion. Products from Wind River Systems, particularly VxWorks, offer a great opportunity to address multiple architectures with the same real-time operating system (RTOS). Furthermore, the continuous development and migration of multicore platforms has increased the focus on migrating software to multicore and performance optimizations given a specified software workload and certain hardware resources.

A fossil that was celebrated last year as a possible "missing link" between humans and early primates is actually a forebearer of modern-day lemurs and lorises, according to two papers by scientists at The University of Texas at Austin, Duke University and the University of Chicago.

Keeping an infrared telescope at very cold operating temperatures isn't an option, it's an absolute necessity. For the James Webb Space Telescope to see the traces of infrared light generated by stars and galaxies billions of light years away, it must be kept at cryogenic temperatures of under 50 Kelvin (-370°F). Otherwise, sunlight would warm the telescope and this heat from the telescope itself will swamp the very faint astronomical signals, effectively blinding the telescope's eye. The job of the huge, five-layer sunshield is to keep that from happening.

The main goal of this article is to focus on the difficulties encountered by SoC integrators when selecting an embedded microcontroller (MCU). Indeed, the selection is based on MCU performances, but the comparison can be difficult and compromised when considering all the parameters influencing these performances.In this article, we will detail how to assess rigorously power consumption, area, speed, code density and processing power for an embedded MCU. For each performance, we will describe how the parameters have to be selected to enable a fair comparison between processor cores.

Simulation enables people with a personal computer to develop very interesting robots, cars, spaceship, and an enormous range of scientific effects with the main limiting factors becoming time and imagination. A novice user with little to no coding experience can use simulation; developing interesting applications in a game-like environment.

While the new multicore system on chip (SoC) signal-processing architecture announced by Texas Instruments this week at Mobile World Congress hits all the right notes with respect to what's needed in next-generation basestation designs, it rings a bit hollow given how sketchy the architectural details remain when contrasted with more 'real' announcements from the likes of Freescale. For sure, the requirements of next-generation basestations will push all architectures to their limits and beyond. Balancing lower power and lower cost with increasingly parallel, math-intensive processing to meet multiuser demands for high-data-rate data in 3GPP Long Term Evolution (LTE) Release 8 all-IP networks is not going to be easy, especially with the introduction of MIMO, beam forming, OFDMA and many other enhancements engineered to maximize spectral efficiency.

Ted Marena of Lattice Semiconductor Corp., points out that designers of digital systems are familiar with implementing the 'leftovers' of their digital design by using FPGAs and CPLDs to glue together various processors, memories, and standard function components on their printed circuit board. In addition to these digital functions, FPGAs and CPLDs can also implement common analog functions using an LVDS input, a simple resistor capacitor (RC) circuit and some FPGA or CPLD digital logic elements to create an analog to digital converter (ADC).

Remember the last time that something a friend did caught you off guard? Probably—and that's because the human brain is specially tuned to remember things that are out of the ordinary. But just how the brain treats those instances has remained uncertain. Some scientists had hypothesized that an unexpected stimulus would trigger a loop that involved both the hippocampus (responsible in part for long-term memory) and nucleus accumbens (involved in reward and pleasure) to make those memories super sticky. But without peering into these centers, researchers could not know for sure.

Although any T. Rex–enthralled kid will tell you that a gigantic asteroid wiped the dinosaurs off the planet, scientists have always regarded this impact theory as a hypothesis subject to revision based on further evidence gathered from around the globe. Other possible causes, such as volcanism and smaller, multiple asteroid strikes, never actually went away, and over the years researchers raised important points that did not fully jibe with a history-changing celestial impact near the Yucatan peninsula one awful day some 65.5 million years ago. A group of 41 researchers have pored over the evidence and decided that—in accordance with the original postulate put forth 30 years ago by a team led by father and son researchers Luis and Walter Alvarez—it was, indeed, a massive asteroid that slammed into Earth, creating Chicxulub Crater on Mexico's Gulf Coast, that killed off many of the species on the planet, including the non-avian dinosaurs.

Today's FPGAs are doubling in capacity every 2 years and have already surpassed the 5 million equivalent ASIC gate mark. With designs of this magnitude, the need for fast flows has never been greater. At the same time, designers are seeking rapid feedback on their ASIC or FPGA designs by implementing quick prototypes or initial designs on FPGA-based boards. These prototypes or designs allow designers to start development, verification and debug of the design—in the context of system software and hardware—and also to fine tune algorithms in the design architecture. Quick and intuitive debug iterations to incorporate fixes are of great value. The ability to perform design updates that don't completely uproot all parts of the design that have already been verified is also a bonus! Whether the goal is aggressive performance or to get a working initial design or prototype on the board as quickly as possible, this paper provides information on traditional and new techniques that accelerate design and debug iterations.

Ice Energy has a novel solution for the electricity challenges of the 21st century: Make Popsicles. Put another way, the company wants to freeze water at night in refrigerator-like boxes adjacent to commercial air conditioners and then thaw it during the day, when power demand is highest. This would theoretically allow AC-hungry commercial buildings in warm climates to cut energy use during heat waves, by shutting air conditioners down while still providing cool air to buildings from melting ice. After seven years of development and testing, the Windsor, Colo.-based company signed an agreement recently with the Southern California Public Power Authority here to deploy some 6,000 Popsicle-making units at 1,500 locations in the utility's service territory around Los Angeles. Ice Energy says the units, called Ice Bears, will lead to a 30 percent fuel reduction for the utility through avoided use of so-called peaker generation plants, which are only turned on when demand is highest.
