#Are self-driving cars a danger to cyclists? Google patents a way for autonomous vehicles to understand hand signals A Google patent has revealed that the firm self-driving cars will be able to detect
and respond to a cyclistshand signals. The documents reveals that the car array of sensors will notice a cyclist among other objects and vehicles on the road.
Google announced its self-driving cars would be capable of doing this last year, but the latest patent reveals new details about how it would work.
HOW DOES GOOGLE'S AUTONOMOUS CAR WORK? Google's prototype two-seater'bubble'cars have buttons to begin and end the drive,
leaving open different possibilities for exactly how Google self-driving cars could work. Google says it begun discussions with most of the world's top automakers in a bid to get self-driving cars on the road by 2020.
In March, a separate patent revealed that Google's self driving car could have airbags both inside and out.
It shows an external airbag system in action that inflates if the car hits a pedestrian or other object.
The head of self-driving cars for Google expects real people to be using them on public roads in two to five years.
Urmson wouldn't give a date for putting driverless cars on roads en masse saying that the system has to be safe enough to work properly.
self-driving cars must have a steering wheel and pedals. Several other states have passed laws formally allowing autonomous cars on public roads without that restriction.

Earlier this week, in response to questions from The Associated press, Google acknowledged 11 minor accidents in the six years it has been testing autonomous cars.
Consumers question whether they can trust self-driving cars to work all the time, who will be liable if there's an accident
and how self-driving cars will interact with regular cars, says the consulting firm J. D. Power and Associates.
In a 2013 survey of U s. drivers, J. D. Power found only one in five was interested in a fully autonomous car.
the head of software for the self-driving car project, says Google's software has gotten much better over the last year at classifying objects, like trees and mailboxes,
Google isn't alone in developing self-driving cars. Mercedes-benz Infiniti and other brands already have advanced driver assistance systems, like lane keeping and adaptive cruise control,
Unlike Google, automakers think self-driving cars will arrive feature-by-feature instead of all at once, giving people plenty of time to adapt to autonomous driving.

#Quantum computers take a leap forward after scientists build qubit logic gate on silicon chip A major step towards building quantum computers capable of performing formidable calculations at a fraction of the speed of current machines has been achieved.
Quantum computing takes advantage of the ability of subatomic particles to exist in more than one state at any time.
In traditional computers available today, data is expressed in one of two states known as binary bits which are either a 1 or a 0. A quantum bit,
or qubit as it is known, can exist in both of these states at once, meaning many computations can be performed in parallel.
For example, two qubits can encode four different values while a three qubit system encodes eight different values.
This would allow new types of computers to be constructed that would far surpass the capabilities of modern super computers.
'We've demonstrated a two-qubit logic gate-the central building block of a quantum computer-and, significantly, done it in silicon.'
'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.'
'Until a few years ago quantum computers were little more than theoretical possibilities, but recent research has shown they could become a realistic proposition.
Both Google and Nasa have been developing a quantum computer as part of their artificial intelligence work. However their D-Wave quantum computer needs to be kept at temperatures of around-273°C(-459°F). The latest research by Professor Dzurak and his colleagues,
which is published in the journal Nature, has shown it is possible to build them using more conventional materials like silicon.
Their work is the first time two qubits have been able to'talk'to each other in a logic gate.
In a quantum computer, data is encoded in the'spin, 'or magnetic orientation, of individual electrons. Not only can they be in one of two'up'or'down'spin states,
so that they can work with qubits instead of bits. Lead author Dr Menno Veldhorst, also from the University of New south wales
'We've morphed those silicon transistors into quantum bits by ensuring that each has only one electron associated with it.'
'The team has taken now out a patent on a full-scale quantum computer chip that could perform functions involving millions of qubits.
These quarks are bound together by strong nuclear force.''In particle physics, every force is mediated by a special kind of force particle,

#New graphene based inks for high-speed manufacturing of printed electronics A low-cost, high-speed method for printing graphene inks using a conventional roll-to-roll printing process,
the method allows graphene and other electrically conducting materials to be added to conventional water-based inks
the first time that graphene has been used for printing on a large-scale commercial printing press at high speed.
Graphene is a two-dimensional sheet of carbon atoms, just one atom thick. Its flexibility, optical transparency and electrical conductivity make it suitable for a wide range of applications,
widespread commercial use of graphene is yet to be realised.""We are pleased to be the first to bring graphene inks close to real-world manufacturing.
There are lots of companies that have produced graphene inks, but none of them has done it on a scale close to this,
"said Dr Tawfique Hasan of the Cambridge Graphene Centre (CGC), who developed the method.""Being able to produce conductive inks that could effortlessly be used for printing at a commercial scale at a very high speed will open up all kinds of different applications for graphene and other similar materials.""
""This method will allow us to put electronic systems into entirely unexpected shapes, "said Chris Jones of Novalia."
"It's an incredibly flexible enabling technology.""Hasan's method, developed at the University's Nanoscience Centre, works by suspending tiny particles of graphene in a'carrier'solvent mixture,
which is added to conductive water-based ink formulations. The ratio of the ingredients can be adjusted to control the liquid's properties,
The same method works for materials other than graphene, including metallic, semiconducting and insulating nanoparticles. Currently, printed conductive patterns use a combination of poorly conducting carbon with other materials, most commonly silver
whereas this new graphene ink formulation would be 25 times cheaper. Additionally, silver is not recyclable,
while graphene and other carbon materials can easily be recycled. The new method uses cheap, nontoxic and environmentally friendly solvents that can be dried quickly at room temperature,
The graphene-based inks have been printed at a rate of more than 100 metres per minute, which is in line with commercial production rates for graphics printing,
Two years ago, Hasan and his colleagues produced a prototype of a transparent and flexible piano using graphene-based inks,
which required no modifications in order to print with the graphene ink. In addition to the new applications the method will open up for graphene,
it could also initiate entirely new business opportunities for commercial graphics printers, who could diversify into the electronics sector."
"In the short to medium term, the researchers hope to use their method to make printed, disposable biosensors,
A zero-index material that fits on a chip could have exciting applications, especially in the world of quantum computing."

The lenses were enclosed then in an all-plastic, 3d printed microscope housing and objective. Once constructed, the microscope provided a field of view of 1. 2 millimeters,
and avenues for commercialization, including non-fouling medical tools and devices, such as implants and scalpels, nozzles for 3d printing and, potentially, larger-scale applications for buildings and marine vessels.
Another avenue for application is functional 3d printing and microarray devices, especially in printing highly viscous and sticky biological and polymeric materials where friction and contamination are major obstacles.
These properties make nitrogen vacancy centers in diamonds candidates for next-generation spin-based quantum devices such as magnetometers, quantum computers,
Individual nitrogen vacancy centers could essentially function as the basic units of quantum computers. Brighter fluorescence intensity is an essential aspect of improving the photon collection efficiency from nitrogen vacancy centers.
In terms of applications, the team's nanostructures may find use in highly sensitive magnetic sensors for making biological observations or within the computational science realm for quantum computing and cryptographic communications.

They tested nitrogen-doped graphene on its own and found it lacked the ability to kick the catalytic process into gear.

Researchers grow nanocircuitry with semiconducting graphene nanoribbons In a development that could revolutionize electronic ciruitry, a research team from the University of Wisconsin at Madison (UW)
and the U s. Department of energy's Argonne National Laboratory has confirmed a new way to control the growth paths of graphene nanoribbons on the surface of a germainum crystal.
and this method provides a straightforward way to make semiconducting nanoscale circuits from graphene, a form of carbon only one atom thick.
"UW researchers used chemical vapor deposition to grow graphene nanoribbons on germanium crystals. This technique flows a mixture of methane, hydrogen and argon gases into a tube furnace.
At high temperatures, methane decomposes into carbon atoms that settle onto the germanium's surface to form a uniform graphene sheet.
when graphene grows on germanium, it naturally forms nanoribbons with these very smooth, armchair edges,"said Michael Arnold, an associate professor of materials science and engineering at UW-Madison."
so all the desirable features we want in graphene nanoribbons are happening automatically with this technique.""Graphene, a one-atom-thick, two-dimensional sheet of carbon atoms, is known for moving electrons at lightning speed across its surface without interference.
This high mobility makes the material an ideal candidate for faster, more energy-efficient electronics. However, the semiconductor industry wants to make circuits start
As a semimetal, graphene naturally has no bandgaps, making it a challenge for widespread industry adoption.
researchers confirmed the presence of graphene nanoribbons growing on the germanium. Data gathered from the electron signatures allowed the researchers to create images of the material's dimensions and orientation.

#FDA approves first 3d printed pill, could signal era of custom medication A new anti-seizure medication has become the first-ever 3d printed medication to gain FDA approval.
The FDA has been pulled along into the future in recent years as prosthetics and other medical devices have been pumped out of 3d printers,
but never before has the technology proven so integral to the production of a pill.
Traditional 3d printing with plastics is done by heating a polymer, then applying it layer by layer to build an object.
The 3d printing technology (called Zipdose) developed by Aprecia Pharmaceuticals isn much different. Each pill is built layer-by-layer to form a porous material with a precisely tuned dose of the medication.
Levetiracetam Aprecia Pharmaceuticals sees Spritam as just the first step into the world of 3d printing pills.
but 3d printing could make it possible for medications to be made custom for patients, even if they require high dosages.
This sort of customization would have been prohibitively expensive prior to 3d printing technology. Aprecia Pharmaceuticals expects to begin selling Spritam in the US sometime in early 2016.
