#Scientists Discover Nutrient Sensor That Senses Amino acid Arginine Through a variety of mechanistic interactions mtorc1 interprets cues in the cellular environment including the availability of nutrients
and signals the organism to act accordingly. mtorc1 is apt to trigger growth during times of abundance
and dial back metabolism when food is scarce. Owing to years of intense scrutiny in the lab of Whitehead Institute Member David Sabatini the key players of this pathway
--whose deregulation is associated with diseases ranging from diabetes to cancer to epilepsy--have gradually been brought to light.
what are the sensors? Now we've found what is likely the first nutrient sensor.
This is what connects that core machinery to the world around it. The finding suggests a model in
Taken together such compelling evidence points to SLC38A9 as an amino acid sensor tipping off the Rags to the availability of nutrients.
It has all the properties consistent with a sensor. As new components of the pathway are identified
Although the discovery of the first nutrient sensor in this pathway represents an important advance the researchers know much work lies ahead.
SLC38A9's specificity for arginine suggests that many more such sensors--for other amino acids and glucose for example--interact either directly or indirectly with mtorc1.

#NIST Develops 16-Antenna Array for Modeling of Wireless communications Channels at 83ghz To help solve the wireless crowding conundrum
and that could offer more than 1000 times the bandwidth of today's cell phone systems. Like pioneers who found land by going west telecom researchers can find open spectrum by going up--to higher frequencies.

Because high-speed digital circuits can easily distort mm wave signals even tiny errors can result in erroneous bits of information.

#Ultrafast Line Scan Sensor from Fraunhofer Identifies Faulty Safety Features in Banknotes In the first half 2014 alone,
For the development of a new sensor, the Austrian research institution has brought the Fraunhofer Institute for Microelectronic Circuits and Systems IMS in Duisburg on board.

#New MIT Power Converter Chip Harvests More than 80%of Energy Realizing that vision, however, will require extremely low-power sensors that can run for months without battery changes or, even better,
that can extract energy from the environment to recharge. Last week, at the Symposia on VLSI Technology And circuits, MIT researchers presented a new power converter chip that can harvest more than 80 percent of the energy trickling into it,
this new chip can do both, and it can power the device directly from the battery.
All of those operations also share a single inductor the chip main electrical component which saves on circuit board space
Nonetheless, the chip power consumption remains low. e still want to have battery-charging capability, and we still want to provide a regulated output voltage,
and we really want to do all these tasks with inductor sharing and see which operational mode is the best.
at very limited input power levels 10 nanowatts to 1 microwatt for the Internet of things. he prototype chip was manufactured through the Taiwan Semiconductor Manufacturing Company's University Shuttle Program.
To control the current flow across their chip, El-Damak and her advisor, Anantha Chandrakasan,
the Joseph F. and Nancy P. Keithley Professor in Electrical engineering, use an inductor, which is a wire wound into a coil.
When a current passes through an inductor, it generates a magnetic field, which in turn resists any change in the current.
Throwing switches in the inductor path causes it to alternately charge and discharge so that the current flowing through it continuously ramps up
however, the switches in the inductor path need to be thrown immediately; otherwise, current could begin to flow through the circuit in the wrong direction,
El-Damak and Chandrakasan use an electrical component called a capacitor, which can store electrical charge.
The higher the current, the more rapidly the capacitor fills. When it full, the circuit stops charging the inductor.
The rate at which the current drops off however, depends on the output voltage, whose regulation is the very purpose of the chip.
Since that voltage is fixed, the variation in timing has to come from variation in capacitance.
El-Damak and Chandrakasan thus equip their chip with a bank of capacitors of different sizes.
As the current drops, it charges a subset of those capacitors, whose selection is determined by the solar cell voltage.
Once again, when the capacitor fills, the switches in the inductor path are flipped. n this technology space,
there usually a trend to lower efficiency as the power gets lower, because there a fixed amount of energy that consumed by doing the work,

#New Conductive Ink Can Print Sensors Onto Wearables Researchers at the University of Tokyo have invented a new conductive ink that can be used to print sensors onto wearable technologies.
The ink will be used in printed electronics, which will allow sensors to be incorporated into electronic apparel for measuring biological data,
including heart rate and muscle contraction. At present, printed electronics, including LEDS, solar panels and transistors, are printed mainly on hard or rigid materials, such as paper or plastics.
For wearable devices, materials would need to be soft and stretchy to be comfortable and well fitting
but it has been challenging to produce an ink that is elastic as well as conductive and can be printed in a simple, single step process.
The team used this ink to produce a wrist-band muscle activity sensor. An elastic conductor was printed onto sportswear material,
and this was combined with an organic transistor amplifier circuit. The sensor features nine electrodes that are placed 2 cm apart from one another in a 3 x 3 grid
and can detect muscle electrical potentials to measure muscle activity y

Kathryn believes that new research integrating electronics directly into the fabric of clothing could move us a step closer to this smart technology.

which converts video images from a miniature video camera worn on his glasses. He can now make out the direction of white lines on a computer screen using the retinal implant.
The images are converted into electrical pulses and transmitted wirelessly to an array of electrodes attached to the retina.
The electrodes stimulate the remaining retina's remaining cells which send the information to the brain.
At present, level designs are limited by how much data can be stored in the RAM-or, strictly, a type of RAM chip called dynamic RAM (DRAM.
3d XPOINT does away with the need to use the transistors at the heart of Nand chips.
Nand works by moving electrons back and forth to an isolated part of the transistors known as their"floating gates"to represent the ones and zeros of binary code.
RAM's speed advantage over traditional storage has made long it the chip of choice to funnel data directly into processors.
One instance when you might want to use the new chips instead of flash would be to store operating system files that are required every time you boot up your machine.
A loop of microtubules encircles the inner plasma membrane of the terminal and anchors mitochondria.

which store the transmitters that convey information between neurons. An intriguing new study of their subcellular structure could help explain how bipolar synaptic terminals meet such excessive energy demands.
Using cutting-edge 3d microscopy, researchers from the National Heart Lung, and Blood Institute and Yale university examined the subcellular architecture of presynaptic terminals in retinal bipolar cells of live goldfish.
Goldfish retinal bipolar cells have giant presynaptic terminals that make them especially amenable for investigation.
Unexpectedly, the team discovered a thick band of microtubules, a component of the cell's cytoskeleton,
that extended from the axon of the neuron into the synaptic terminal and then looped around the interior periphery of the terminal.
The microtubule band appeared to associate with mitochondria--organelles known for providing energy to cells--in the synaptic terminal.
and never made it to the synaptic terminal. The findings suggest that these previously unknown microtubule structures provide a"roadway"for the transport of mitochondria crucial to maintain energy supplies into the synaptic terminals of these highly active neurons associated with vision.
