The new chips could help meet demands of future cloud computing and Big data systems, cognitive computing, mobile products and other emerging technologies, according to IBM,
which developed the chip as part of a $3 billion research effort with Samsung and Globalfoundries at the State university of New york at Albany.
Most chips today in PCS and other devices use microprocessors between 14 and 22 nanometers.
Scientists have wanted long to create a teensy"light bulb"to place on a chip, enabling what is called photonic circuits,
"Current applications for microfluidic chips include serving as miniaturized chemistry and biology laboratories. Instead of performing experiments with dozens of test tubes, each droplet in a lab-on-a-chip can serve as a microscopic test tube,
The core of the new microfluidic chip, which is about half the size of a postage stamp,
The layout of the bars on these new microfluidic chips is analogous to the layout of circuits on microchips, controlling interactions among the droplets.
"Making the droplets smaller will allow the chip to carry out more operations, "Prakash said. The researchers now plan to make a design tool for these droplet circuits available to the public,

like multiple-die stacking with flip-chip, side-by-side heterogeneous integration, and 3d partitioning of different CMOS dies issued from CMP runs. 3d integration is highly complementary to traditional CMOS scaling,
These 3d post-process technologies require very limited redesign of existing chips, and will be used initially for specific CMOS nodes available at CMP.
"The new technology--called Cluster-Chip--was developed with support from a Quantum Grant from NIBIB,
Toner and his collaborator Dr. Daniel Haber, M d.,Ph d.,also at MGH, recently used Cluster-Chip to capture
The chip is designed to slowly push blood through many rows of microscopic triangle-shaped posts.
and continue through the chip until reaching the next tip; however CTC clusters are left at the tip,
To determine the efficiency of Cluster-Chip, the researchers introduced fluorescently tagged cell clusters (ranging from 2-30 cells) into the chip
and counted the number of clusters that were captured and the number that flowed through undetected.
At a blood flow rate of 2. 5ml/hr, the chip captured 99 percent of clusters containing four or more cells, 70 percent of three-cell clusters,
Comparison of the clusters under a microscope before and after capture found that the chip had no negative effects on the integrity of the clusters as a whole.
The researchers next compared the efficiency of their novel chip to two currently-used methods that have had some success capturing CTC clusters.
the Cluster-Chip was significantly more efficient than a filter-based method, which pushes blood through a membrane with pores only large enough to let single cells pass through.
The chip was also more efficient than a different microfluidic chip--previously developed by Toner--that isolates CTCS
The results highlight the importance of the unique Cluster-Chip capture technique which is based on the structural properties of CTC clusters rather than their size or the presence of surface proteins.
This latter property makes the Cluster-Chip well-suited for capturing CTC clusters from a range of cancer types,
In this study, the chip captured CTC clusters in 11 of 27 (40.7 percent) breast cancer patients, 6 of 20 (30 percent) melanoma patients
"Toner anticipates that the Cluster-Chip will play an important role in stimulating new research on CTC cluster biology:"

#Toward quantum chips: Packing single-photon detectors on an optical chip is crucial for quantum-computational circuits Single-photon detectors are notoriously temperamental:
Of 100 deposited on a chip using standard manufacturing techniques only a handful will generally work.
In a paper appearing today in Nature Communications the researchers at MIT and elsewhere describe a procedure for fabricating
and then transferring those that work to an optical chip built using standard manufacturing processes.
The researchers'process begins with a silicon optical chip made using conventional manufacturing techniques. On a separate silicon chip they grow a thin flexible film of silicon nitride upon
They then press a tungsten probe typically used to measure voltages in experimental chips against the silicone.
Even on-chip detectors deposited individually have topped historically out at about 2 percent. But the detectors on the researchers'new chip got as high as 20 percent.
That's still a long way from the 90 percent or more required for a practical quantum circuit but it's a big step in the right direction n
