At 10mm across, the chip is small enough to be installed inside double glazing on the frame that separate the two glass panes. hanks to this window space,
On the chip are magnetic and acceleration sensors that measure how far the window is open,
and radio that communicates this information to a basestation. Challenge one was to deposit a solar cell directly on a die,
Secondly, the chip needed to run from a tiny solar cell, in the winter, and through the night. y keeping both processor and chip extremely small, the latter is extremely frugal.
In addition, the researchers constructed switches that consume little energy, and engineered very short radio protocols,
said Fraunhofer. dding to the overall conservation of power is the fact that the sensor always switches to sleep mode.
the sensor can be set so that it wakes up every few minutes, or even seconds,
In the window application, sensors on the chip measure tilt and report if it is open
The chip also detects shock, and Fraunhofer claims can differentiate between a ball hitting the glass

Bending light with a microchip The Defense Advanced Research Projects Agency (DARPA) has demonstrated solid-state optical phased array technology in a microchip bringing the ability to bend light to the battlefront.

DARPA breakthrough 3 uses a microchip to control the light, vastly different to existing methods.

Those researchers built a series of pipes for light (phase shifters) on a microchip, which is able to slows down
The timed light waves are delivered then to tiny array elements within a grid on the chip.
by means of a roll-on coating consisting of a honeycomb of electrodes (see bottom right image).
whereby opaque, charged particles (approx. 1 micron in size) are attracted to electrodes that posses an opposite charge.
Thus the electric field created between the two electrodes causes the flow of these particles back and forth.
The interaction of incoming light with each electrophoretic pixel (two electrodes) depends on the position of the particles relative to these electrodes,
In reference to these, the device uses electrophoresis to attract charged color particles to the top transparent electrode to preadtheir color,
which are adjacent to the electrode. The device is filled with dual-colour, dual-particle colloidal dispersion inks.
It is common in e-ink displays to use sub-pixels (i e. multiple electrodes to do some fancy charged transport),
They use three electrodes and by altering the applied voltages between them all, many color states are created during operation,

Even more ambitiously, the team also connected a camera to their antenna. This was a low-power sensor capable of producing 174×144 pixel black and white images,

#Rare case uncovers missing clue to Fragile X Fragile X syndrome may not only be a problem of receivers in the brain letting in too much information.
A new study finds that transmitters may be sending out too much data, as well. The findings raise the possibility that drugs recently tested as treatments for fragile X may be ineffective, at least in part,
because they only dialed down the brain receivers, presumably leaving transmitters on overdrive. Scientists made the discovery by studying the case of someone who doesn even have the disordernly two of its classic symptoms.
In patients with fragile Xhe most common cause of inherited intellectual disability key gene is disabled completely
Like radio transmitters and receivers, brain cells send and receive transmissions in fine-tuned ways that separate the signals from the noise.
Until recently, most fragile X research has focused on problems with overly sensitive receivers, those that allow in too much information.
published in the Proceedings of the National Academy of Sciences, suggests that fragile X likely also causes overactive transmitters that send out too much information. he mechanisms that researchers have thought long were the entirety of the problem with fragile X are obviously still very much in play,
In other words, the patient brain cells had entirely normal receivers, which appeared to work in ways that were indistinguishable from those in healthy people. his single point mutation does not seem to affect the classical,
Surprisingly, the fruit fly studies indicated that this single mutation increased the number of transmitters in brain cells, implicating a fundamental problem in
causing transmitters to send out too much information. In the new study researchers were able to verify the same effect from just the mutation and link it to human disease.

"The chip is designed to funnel blood through a field of microscopic triangle-shaped posts. The posts are arranged so that every two posts channels cells towards the tip of a third post.
