Call of Duty: Advanced Warfare DNA Bomb on Comeback 40-3 with 6 Dom Caps
DNA Bomb using my shiny new ASM1 Speakeasy! Played the objective at first but then decided to go for the DNA and got it right as we hit the point cap. Rough start, but finished with a 30 kill...

SEYNE-LES-ALPES, France Jewelry and pieces of clothing were being removed from Germanwings crash victims on Friday and helicoptered out, police said Friday, as forensics teams ramped up DNA testing.

The grim task of recovering and identifying the 150 bodies intensified after relatives provided DNA samples in emergency tents set up near the crash site in a remote corner of the French Alps. The Germanwings flight smashed into the ground at 430 mph on Tuesday, pulverizing the wreckage.

"Intense efforts continue today to recover bodies and evidence for identification of victims," French police spokesman Lt. Col. Xavier Vielenc told reporters at a staging site near the town of Seyne-Sur-Alpes. "Investigators are bringing back anything that can help to identify victims such as jewelry, pieces of clothing."

He said four helicopters were flying 15 investigators to the mountainside where the Airbus A320 crashed, with each investigator was accompanied by police officer.

"Each team of two is dropped down into the crash site like a buddy system in diving," Vielenc explained. "It is an 80 meter [260 feet] drop to the crash site by winch from the helicopter."

Ten of the 15 investigators are dedicated to DNA analysis, he said. Six more workers are responsible for transferring bodies and evidence back to the Post Command Operations site where tents have been erected for recovery teams and counselors.

Victims' relatives who on Thursday attended a memorial service and visited the area of the crash "gave DNA in these tents last night," he said.

Thirty forensic experts from the national French police service, IRCGN, are working in the tents, Vielenc added. Interpol has said its experts are assisting.

In the town of Le Vernet, a shrine set up by residents in memory of the victims was visited by a young Spanish couple who laid single flowers and a bouquet offered by officials from the Spanish embassy.

The mayor, Francois Baliquette, said the town "belonged" to the victims' families and that 19 of them had decided to stay on in the area after Thursday's visit.

Jewelry, Clothing: DNA Experts Toil Over Victims' IDs

The latest DNA nanodevices created at the Technische Universitaet Muenchen (TUM) -- including a robot with movable arms, a book that opens and closes, a switchable gear, and an actuator -- may be intriguing in their own right, but that's not the point. They demonstrate a breakthrough in the science of using DNA as a programmable building material for nanometer-scale structures and machines. Results published in the journal Science reveal a new approach to joining -- and reconfiguring -- modular 3D building units, by snapping together complementary shapes instead of zipping together strings of base pairs. This not only opens the way for practical nanomachines with moving parts, but also offers a toolkit that makes it easier to program their self-assembly.

The field popularly known as "DNA origami," in reference to the traditional Japanese art of paper folding, is advancing quickly toward practical applications, according to TUM Prof. Hendrik Dietz. Earlier this month, Dietz was awarded Germany's most important research award, the Gottfried Wilhelm Leibniz Prize, for his role in this progress.

In recent years, Dietz and his team have been responsible for major steps in the direction of applications: experimental devices including a synthetic membrane channel made from DNA; discoveries that cut the time needed for self-assembly processes from a week to a few hours and enable yields approaching 100%; proof that extremely complex structures can be assembled, as designed, with subnanometer precision.

Yet all those advances employed "base-pairing" to determine how individual strands and assemblies of DNA would join up with others in solution. What's new is the "glue."

"Once you build a unit with base pairs," Dietz explains, "it's hard to break apart. So dynamic structures made using that approach tended to be structurally simple." To enable a wider range of DNA nanomachines with moving parts and potentially useful capabilities, the team adapted two more techniques from nature's biomolecular toolkit: the way proteins use shape complementarity to simplify docking with other molecules, and their tendency to form relatively weak bonds that can be readily broken when no longer needed.

Bio-inspired flexibility

For the experiments reported in Science, Dietz and his co-authors -- doctoral candidates Thomas Gerling and Klaus Wagenbauer, and bachelor's student Andrea Neuner from TUM's Munich School of Engineering -- took inspiration from a mechanism that allows nucleic acid molecules to bond through interactions weaker than base-pairing. In nature, weak bonds can be formed when the RNA-based enzyme RNase P "recognizes" so-called transfer RNA; the molecules are guided into close enough range, like docking spacecraft, by their complementary shapes.

The new technology from Dietz's lab imitates this approach. To create a dynamic DNA nanomachine, the researchers begin by programming the self-assembly of 3D building blocks that are shaped to fit together. A weak, short-ranged binding mechanism called nucleobase stacking can then be activated to snap these units in place. Three different methods are available to control the shape and action of devices made in this way.

"What this has given us is a tiered hierarchy of interaction strengths," Dietz says, "and the ability to position -- precisely where we need them -- stable domains that can recognize and interact with binding partners." The team produced a series of DNA devices -- ranging from micrometer-scale filaments that might prefigure technological "flagella" to nanoscale machines with moving parts -- to demonstrate the possibilities and begin testing the limits.

For example, transmission electron micrographs of a three-dimensional, nanoscale humanoid robot confirm that the pieces fit together exactly as designed. In addition, they show how a simple control method -- changing the concentration of positive ions in solution -- can actively switch between different configurations: assembled or disassembled, with "arms" open wide or resting at the robot's side.

Virginia Polytechnic Institute and State University, more often known as Virginia Tech, is using high-performance computing (HPC) in the Microsoft Azure cloud, together with parallel laptop computing, to support a cancer research programme.

Wu Feng, a professor of computer science at Virginia Tech, said: We looked at trying to empower cancer biologists to tackle problems they would not be able to tackle by unleashing the power of parallel computing to the masses, enabling discoveries to be made faster.

Feng said the computer industry is unable to keep up with the data processing requirements of DNA sequencing. "DNA sequencing has accelerated faster than we can compute. The amount of data coming out of DNA sequencing doubles every six months, while computing power only doubles every 24 months."

The university has used Microsoft Azure to enable Feng and the team of researchers to keep up with DNA sequencing data growth.

When I first started this research, we doubled DNA data every 12 months, then it went to nine months, then to six, said Feng.

From a computational perspective, quadrupling the technology is cost prohibitive, since the requirements of the DNA researchers outpace the economic model based on Moores Law, which the IT industry generally follows.

While it is possible to buy twice as much for the same financial outlay every 18 months to two years, as stipulated by Moores Law, according to Feng the researchers needed four times as much IT every two years.

We needed to look at innovative tools to avoid having to quadruple IT resources every six months, he said.

An exhaustive search on the genome involves a medium-sized dataset, but Feng said processing involves big compute and big output data. He said next-generation DNA sequence analysis will involve big input data, big compute, and the application could output anything from small to very large datasets.

The university tried building a proof-of-concept application using its supercomputer, called HokiSpeed a 400-processor system with 2,400 CPU cores and 400 GPU cards, where each GPU card used 400 cores. This machine made the supercomputer Top500 list a few years ago but, according to Feng, it timed out when the researchers tried to run the proof-of-concept DNA analytics application.
