Wonder which 3D printer she used?
Together with scientists, fashion designers have used graphene — a Nobel-Prize winning material that’s tougher than diamonds — to give their LBD a high-tech cut.
“We are trying to showcase the amazing properties of graphene,” Francesca Rosella, the co-founder of fashion company CuteCircuit, told CNN.
Graphene is extremely versatile and ideal for biosensor technology, BMI, etc. we really have just began understanding its capabilities.
An international team of researchers under the umbrella of the EU-funded Graphene Flagship have taken a significant step in thermal infrared (IR) photodetctors with the development of the most sensitive uncooled graphene-based thermal detector yet fabricated. These new photodetectors, known as bolometers, are so sensitive that they can register the presence of a scant few nanowatts of radiation. That level of radiation is about a thousandth of what would be given off by a hand waving in front of the detector.
In the research described in the journal Nature Communications, scientists from the University of Cambridge, UK; the Institute of Photonic Sciences (ICFO), Spain; the University of Ioannina, Greece; and from Nokia and Emberion found that the combination of graphene and pyroelectric materials—which generate a voltage when they are heated or cooled—yields a unique synergy that boosts the performance of thermal photodetectors.
The actual design of the device is fairly simple. The pyroelectric material acts as the substrate; a conductive channel made from single-layer graphene runs through it, and a floating gate electrode floats above it.
Wish these guys a lot of luck; however, they need to hurry up soon as China is already had a head start with QC.
As we saw during the 2016 US election, protecting traditional computer systems, which use zeros and ones, from hackers is not a perfect science. Now consider the complex world of quantum computing, where bits of information can simultaneously hold multiple states beyond zero and one, and the potential threats become even trickier to tackle. Even so, researchers at the University of Ottawa have uncovered clues that could help administrators protect quantum computing networks from external attacks.
“Our team has built the first high-dimensional quantum cloning machine capable of performing quantum hacking to intercept a secure quantum message,” said University of Ottawa Department of Physics professor Ebrahim Karimi, who holds the Canada Research Chair in Structured Light. “Once we were able to analyze the results, we discovered some very important clues to help protect quantum computing networks against potential hacking threats.”
Quantum systems were believed to provide perfectly secure data transmission because until now, attempts to copy the transmitted information resulted in an altered or deteriorated version of the original information, thereby defeating the purpose of the initial hack. Traditional computing allows a hacker to simply copy and paste information and replicate it exactly, but this doesn’t hold true in the quantum computing world, where attempts to copy quantum information-or qudits-result in what Karimi refers to as “bad” copies. Until now.
Nice write up. What is interesting is that most folks still have not fully understood the magnitude of quantum and how as well as why we will see it as the fundamental ingredient to all things and will be key in our efforts around singularity.
When it comes to studying transportation systems, stock markets and the weather, quantum mechanics is probably the last thing to come to mind. However, scientists at Australia’s Griffith University and Singapore’s Nanyang Technological University have just performed a ‘proof of principle’ experiment showing that when it comes to simulating such complex processes in the macroscopic world quantum mechanics can provide an unexpected advantage.
Griffith’s Professor Geoff Pryde, who led the project, says that such processes could be simulated using a “quantum hard drive”, much smaller than the memory required for conventional simulations.
“Stephen Hawking once stated that the 21st century is the ‘century of complexity’, as many of today’s most pressing problems, such as understanding climate change or designing transportation system, involve huge networks of interacting components,” he says.

Astronomers have discovered a large void in the universe and it appears that the Milky Way and our neighboring galaxies are running away from it at about 630 kilometers per second (1.5 million miles per hour).
In a paper published in Nature Astronomy, an international group of astronomers has studied the velocities of the galaxies around our own and how they compare to the cosmic microwave background. By combining the observations with rigorous statistical analysis, the researchers have been able to map the gravitational distribution of the (somewhat) local universe.
Astronomers know that what is called the “local group” of galaxies are moving towards a dense region called the Shapley attractor. The team, led by Yehuda Hoffman from the Hebrew University of Jerusalem, realized how the gravitational lines seemed to all point towards the Shapley attractor and away from an unknown region. They suspect this region is a large void we are “escaping”.
