Engineers develop a computer that operates on water droplets The computer is nearly a decade in the making,
The work combines his expertise in manipulating droplet fluid dynamics with a fundamental element of computer science--an operating clock."
Because of its universal nature, the droplet computer can theoretically perform any operation that a conventional electronic computer can crunch,
or to operate word processors on this, "Prakash said.""Our goal is to build a completely new class of computers that can precisely control
and manipulate physical matter. Imagine if when you run a set of computations that not only information is processed
but physical matter is manipulated algorithmically as well. We have made just this possible at the mesoscale.""The ability to precisely control droplets using fluidic computation could have a number of applications in high-throughput biology and chemistry,
and possibly new applications in scalable digital manufacturing. Arrayarrayfor nearly a decade since he was in graduate school,
Computer clocks are responsible for nearly every modern convenience. Smartphones, DVRS, airplanes, the Internet--without a clock, none of these could operate without frequent and serious complications.
Nearly every computer program requires several simultaneous operations each conducted in a perfect step-by-step manner. A clock makes sure that these operations start
and stop at the same times, thus ensuring that the information synchronizes. The results are dire if a clock isn't present.
"The reason computers work so precisely is that every operation happens synchronously; it's what made digital logic so powerful in the first place,
Arraydeveloping a clock for a fluid-based computer required some creative thinking. It needed to be easy to manipulate,
allowing observation of computation as it occurs in real time. The presence or absence of a droplet represents the 1s and 0s of binary code
and the clock ensures that all the droplets move in perfect synchrony, and thus the system can run virtually forever without any errors."
and demonstrates building blocks for synchronous logic gates, feedback and cascadability--hallmarks of scalable computation. A simple-state machine including 1-bit memory storage (known as"flip-flop")is demonstrated also using the above basic building blocks.
"Prakash said the most immediate application might involve turning the computer into a high-throughput chemistry and biology laboratory.
and the droplet computer offers unprecedented control over these interactions. From the perspective of basic science, part of why the work is so exciting,
is that it opens up a new way of thinking of computation in the physical world.
Although the physics of computation has been applied previously to understand the limits of computation the physical aspects of bits of information has never been exploited as a new way to manipulate matter at the mesoscale (10 microns to 1 millimeter.
Right now, anyone can put these circuits together to form a complex droplet processor with no external control--something that was a very difficult challenge previously,
computation takes a special place. We are trying to bring the same kind of exponential scale up because of computation we saw in the digital world into the physical world
#How a gut feeling for infection programs our immune response An unexpected finding by an international team of scientists based at The University of Manchester
These cells are called rapidly to sites of infection and injury and have an amazing ability to change
It has always been assumed that the programming takes place once the cells arrive at the point of injury
Using mouse models Dr Grainger and his team looked at how and where monocytes are programs in response to toxoplasmosis,
and puts the early signals coming out from the gut at the centre of monocyte programming.
At the moment a lot of therapies are focused on the site of infection or injury itself but this data suggests that it's the signals that are being sent out from the gut that are impacting the whole immune system.
It might even be possible to develop drugs to target the programming mechanisms within the bone marrow,
although at the moment we don't know enough about the bone marrow to do this, which is why our research is so important."
"On top of uncovering the long-range signaling mechanisms the researchers were astounded by another aspect of the programming

#Supercomputers surprisingly link DNA crosses to cancer Supercomputers have helped scientists find a surprising link between cross-shaped (or cruciform) pieces of DNA and human cancer, according to a study at The University of Texas at Austin (UT Austin.
High performance computing at UT Austin's Texas Advanced Computing Center (TACC) with the Stampede and Lonestar supercomputers helped the researchers find short inverted repeats of 30 base pairs
and under in a reference database of mutations in human cancer that are somatic, meaning not inherited.
Bacolla is a research associate in the Vasquez Lab.'What we found in our study was that the sites of chromosome breaks are not random along the DNA double helix;
We used the TACC supercomputers for that aspect of the work.''''We have used both the Stampede and the Lonestar Linux clusters.
We usually back up our data on Corral, 'Bacolla said. The challenge and need for using HPC,
said Bacolla, is that the time required to find all combinations of inverted repeats, given a DNA sequence is enormous.
The Vasquez team designed their algorithm to take a string of letters corresponding to the DNA bases A-t-C-G
'We needed to compare the frequencies of inverted repeats found in the COSMIC data set with those that we would find in control, by chance.'
'COSMIC is maintained a database by the Sanger Institute in the U k. of mutations found in human somatic, or noninheritable cancer.'
'We had 20,000 translocations from human cancers from the COSMIC database; 200 bases of DNA for each translocation;
We certainly cannot do this kind of work on our laptop or anything like a normal system in our laboratories;
when he tried to scale up to 100 or more sequences on one processor.''To solve this, we had to get in touch with TACC support staff,
Finally, we ended up with a solution by giving to each processor fewer sequences.''This allowed Bacolla to scale his code up and use over 1, 000 processors at once.'
'It would not have been possible to do this job without the TACC resources, 'Bacolla said.''The center is an incredible resource in terms of its capacity and support.
'Our next steps are to go forward with a mouse model that can detect mutations and translocations in the mouse genome using human sequences from these cancer breakpoints,
'Vasquez said. Does this really occur now in the context of chromosomes in living organisms?
'Vasquez sees a bright future in the intertwining of computation and the life sciences.''I think the potential of the computational analysis is mind-blowing.
#Miniscule mirrored cavities connect quantum memories The enhanced interactions between light and atoms and the extended spin-coherence times are essential steps toward realizing real-world quantum memories and, hence, quantum computing systems,
which could solve some problems faster than conventional systems. Additionally, these advances could significantly impact the development of high-security, long-distance, cryptographic fiber optic communication networks.
Nanoscale mirrored cavities that trap light around atoms in diamond crystals increase the quantum mechanical interactions between light and electrons in atoms.
This improvement in the coherence time is more than two orders of magnitude better than previously reported times for cavity-coupled single quantum memories in solid state systems.

#Ultrasonic fingerprint sensor may take smartphone security to new level A new ultrasonic fingerprint sensor measures 3-D image of your finger's surface

#New method of quantum entanglement packs vastly more data in a photon A team of researchers led by UCLA electrical engineers has demonstrated a new way to harness light particles,

The ferrite cores are designed optimally to reduce the core volume by half, and their ability to transfer power is unaffected nearly by human bodies or surrounding metal objects,
This has made it possible for mobile devices to receive power from any direction. Although wireless-power technology has been applied to smartphones
it could not offer any substantial advantages over traditional wired charging because the devices still require close contact with the transmitter,
the WPT technology should provide mobile users with six degrees of freedom at a distance.
Until now, all wireless-charging technologies have had difficulties with the problem of short charging distance, mostly less than 10 cm,
