#A New Chip Could Add Motion Sensing to Clothing A company called mcube has made a new kind of accelerometer, the device that senses motion from inside a smartphone or fitness monitor.
Accelerometers are made usually of two chips: a mechanical device that detects movement, and a microchip that makes sense of the signal from the first chip.
By integrating those components on a single chip, mcube has reduced not only the size of the device
but achieved a higher-quality signal. In fact, the company says its new accelerometer is sensitive enough to replace the gyroscope in a smartphone.

#Terahertz Chip Identifies Short Strands of DNA One of the more significant practical challenges currently occupying molecular biologists is to find better ways of identifying short strands of DNA.
#IBM Chip Processes Data Similar to the Way Your Brain Does A new kind of computer chip,
the chip consumes significantly less power, and is suited vastly better to processing images, sound, and other sensory data.
IBM Synapse chip processes information using a network of just over one million eurons, which communicate with one another using electrical spikess actual neurons do.
The chip uses the same basic components as today commercial chipsilicon transistors. But its transistors are configured to mimic the behavior of both neurons and the connectionsynapsesetween them.
The Synapse chip breaks with a design known as the Von neumann architecture that has underpinned computer chips for decades.
Although researchers have been experimenting with chips modeled on brainsnown as neuromorphic chipsince the late 1980s,
Details of the chip were published today in the journal Science. The new chip is not yet a product,
but it is powerful enough to work on real-world problems. In a demonstration at IBM Almaden research center, MIT Technology Review saw one recognize cars, people,
and it consumed 100,000 times as much power as the IBM chip. IBM researchers are now experimenting with connecting multiple Synapse chips together,
and they hope to build a supercomputer using thousands. When data is fed into a Synapse chip it causes a stream of spikes,
and its neurons react with a storm of further spikes. The just over one million neurons on the chip are organized into 4, 096 identical blocks of 250,
an arrangement inspired by the structure of mammalian brains, which appear to be built out of repeating circuits of 100 to 250 neurons,
Programming the chip involves choosing which neurons are connected, and how strongly they influence one another. To recognize cars in video, for example,
a programmer would work out the necessary settings on a simulated version of the chip, which would then be transferred over to the real thing.
or any chip IBM has made ever, with over five billion, it consumes strikingly little power.
Server chips with similar numbers of transistors consume tens of watts of powerround 10,000 times more.
IBM new chip doesn have separate memory and processing blocks, because its neurons and synapses intertwine the two functions.
The new chip ay be a historic development, he says. he very low power consumption and scalability of this architecture are really unique.
even the best programmers find learning to work with the chip bruising, says Modha: t almost always a frustrating experience.
Asking the industry to adopt an entirely new kind of chip and way of coding may seem audacious.
because it is becoming clear that current computers won be able to deliver much more in the way of performance gains. his chip is coming at the right time,
helping to further increase the amount of information that can be packed onto a single chip. RRAM can also operate a hundred times faster than flash.
so it should be easier to integrate the memory storage with other electronics on a chip.
But the individual memory units on a flash chip require three connections, which makes forming multiple layers of memory difficult and expensive.
It boasts blue-chip customers including General electric Procter & gamble and Schneider Electric but it faces blistering competition from EMC Syncplicity and Citrix Sharefile as well as Microsoft Onedrive Google Drive and a host of others.
