"or transferred quantum information carried in light particles over 100 kilometers (km) of optical fiber, four times farther than the previous record.
Arraythe lead author, Hiroki Takesue, was a NIST guest researcher from NTT Corp. in Japan.
"Until now, so much quantum data was lost in fiber that transmission rates and distances were low. The new NTT/NIST teleportation technique could be used to make devices called quantum repeaters that could resend data periodically
in order to extend network reach, perhaps enough to eventually build a"quantum internet.""Previously, researchers thought quantum repeaters might need to rely on atoms or other matter, instead of light,
a difficult engineering challenge that would also slow down transmission. Various quantum states can be used to carry information;
the NTT/NIST experiment used quantum states that indicate when in a sequence of time slots a single photon arrives.
The experiments were performed at wavelengths commonly used in telecommunications. Because the experiment filtered out and focused on a limited combination of quantum states
Tactile sensors are data acquisition devices that detect and measure a diversity of properties arising from physical interaction
Against the backdrop of healthy mouse tissue, rogue metastatic cells from the human tumor stick out like flares.
The researchers developed a new method using flow cytometry that let them capture individual human metastatic cancer cells traveling through the mouse's blood
Whereas 44 percent of control mice (11 of 25) developed secondary tumors within four weeks, researchers could only find metastatic cells in one drug-treated mouse (4 percent.

the researchers combed through databases of phage genomes looking for sequences that appear to code for the key tail fiber section, known as gp17.
-and-answer experiment Researchers used a brain-to-brain interface they developed to allow pairs of participants to play a'20 question'style game by transmitting signals from one brain to another over the Internet.
The respondent is shown an object (for example, a dog) on a computer screen, and the second participant,
With the click of a mouse, the inquirer sends a question and the respondent answers"yes"or"no"by focusing on one of two flashing LED LIGHTS attached to the monitor,
which flash at different frequencies. A"no"or"yes"answer both send a signal to the inquirer via the Internet
and activate a magnetic coil positioned behind the inquirer's head. But only a"yes"answer generates a response intense enough to stimulate the visual cortex
and cause the inquirer to see a flash of light known as a"phosphene.""The phosphene--which might look like a blob,
or by the brain signal transmission being interrupted by hardware problems.""While the flashing lights are signals that we're putting into the brain,

Because we use essentially the same device technology as existing computer chips, we believe it will be much easier to manufacture a full-scale processor chip than for any of the leading designs,
which rely on more exotic technologies.""This makes the building of a quantum computer much more feasible,
since it is based on the same manufacturing technology as today's computer industry, "he added. The advance represents the final physical component needed to realise the promise of super-powerful silicon quantum computers,
which harness the science of the very small--the strange behaviour of subatomic particles--to solve computing challenges that are beyond the reach of even today's fastest supercomputers.
In classical computers, data is rendered as binary bits, which are always in one of two states:
A qubit operation exploits this quantum weirdness by allowing many computations to be performed in parallel (a two-qubit system performs the operation on 4 values, a three-qubit system on 8, and so on."

MATLAB is a high-level language and interactive environment used by millions of engineers and scientists to explore
"Such data allows us to answer basic questions about developmental biology and the role of physics in shaping the developing body,"Heemskerk added.
The downside of high-resolution recordings is the resulting very large data set.""A 10-hour recording is easily 2 terabytes (TB),
which exceeds the hard drive capacity of most computers and would take 100 hours to transfer with a good Internet connection,
"said Heemskerk.""That makes it challenging to extract the information we want from the data."
"Often in biology, the action is curved on a surface of interest. Although the recording of the cube containing this surface is 2 TB,
the surface itself is only a few gigabytes. Imsane takes advantage of this by isolating the surface

#Sharp batshit crazy new smartphone isa robot PHOTOS If you ever thought the good olphablet was a bit cumbersome
Earlier today, Japanese electronics maker Sharp revealed a humanoid robot-shaped smartphone that I promise won fit in your skinny jeans. It hard to say if it more phone or robot,
but Robohon (yes, an amalgamation of robot and phone) attracted a whole lot of attention at this afternoon press-only preview event at the annual CEATEC convention just outside Tokyo.
The 19.5-centimeter (7. 7-inch 390 gram (0. 9-pound) Robohon sports a 2-inch touchscreen, a quad-core CPU,
and can connect to 3g, LTE, and wifi networks but who cares! It a freakinrobot that makes phone calls, shoots pictures and videos,
and sends emails! A Sharp spokesperson tells Tech in Asia that the robot has an original operating system that not based on Android (the company consumer smartphones have traditionally been powered by Google OS.
Robohon can sit, stand, walk, dance it can even beam a movie or slideshow on your wall with its built-in projector.
But wait, there more! Robohon also utilizes artificial intelligence that learns your likes, dislikes, daily habits,
and frequently-visited places the more you use it. Its facial and voice recognition functions allow it to tell users apart,
so it will respond differently when talking to your spouse or children. At this point, Robohon feels almost like a miniature version of Softbank Pepper robot
but Sharp spokesperson says that the cute little guy is not yet tied up with any of Japan major telcos.
