Radar warns motorcycle pilots of nearby traffic before they even see the oncoming cars

Radar warns motorcycle pilots of nearby traffic before they even see the oncoming cars | numeric | Scoop.it

Radar warns motorcyclists of nearby traffic before they see oncoming cars. Motorcyclists are 18 times more likely to be killed in a collision. This new technology is about to change that. The claim is that this new radar could prevent nearly one-third of all motorcycle accidents.

RADAR technology initially developed for use in driverless cars has been adapted for motorcycles. Vehicle-to-vehicle communications developer Cohda Wireless from South Australia has partnered with Bosch, Ducati and Autotalks on a “digital protective shield” that warns riders of nearby traffic before they see oncoming cars. Bosch is commercializing the technology in Ducati production bikes but the radar could also be retrofitted to any car or motorcycle.

Production of the technology is being driven by a proposed mandate from the United States Department of Transportation that would require all new vehicles to have vehicle-to-vehicle radars installed. Cohda Wireless Managing Director Paul Gray said the radar was the next step in safety from seatbelts and airbags. “Technologists have gone as far as they can in terms of minimizing harm during an accident and now it is about avoiding the accidents before they even happen,” he said.

“If a motorcyclist is riding down the street, it will be alerted when a car turning onto the same road creates an opportunity for an accident. This can also happen when the car moving onto the road is not visible to the rider. The radar will also alert drivers who are changing lanes if someone is in their blind spot, which is quite an issue for motorcyclists.”

Gray said the technology would eventually be in every autonomous car as well. Cohda commands about 60% of the vehicle-to-vehicle communication market. The system uses the public WLAN standard (ITS G5) as the basis for the exchange of data between motorcycles and cars.

I expect my future workplace, no matter where it is, to employ new safety techniques and to be constantly thinking of new ways to improve safety.

 

In this article, the author talks about a technology called 'RADAR', which has been developed for motorcyclists. It warns 'motorcyclists of nearby traffic before they see the oncoming cars'. I believe this technology is essential to the safety development of any country. I hope to see RADAR or a similar program introduced into Australia in the years to come. Not only will it reduce the alarming number of motorcycle accidents, but with further advancement it could reduce the accident rate of bigger vehicles such as cars and trucks. 

 

In this growing 21st century, we can achieve amazing things, so why can we not reduce accident and injury rates?

Self-driving and electric cars will have tons of strange effects on society

Self-driving and electric cars will have tons of strange effects on society | numeric | Scoop.it

Autonomy and electrification will have bigger impacts on the world than you might expect.

First, a bit of managing expectations: without regulatory incentives, America’s electric car adoption looks like it will be slow to grow, and the first wave of autonomous cars might prove to be rather underwhelming. And while automakers and technology firms are indeed racing to reboot our cars—making these technologies seemingly inevitable—they are likely to take a while to get here.

What's less certain is how they'll change the world. Benedict Evans, a partner at the Silicon Valley venture capital firm Andreessen Horowitz and no stranger to tech trends analysis, has published some thoughts on what he calls second- and third-order effects of the disruption that’s going to play out on our highways. And his insights describe a future made fundamentally different by the technologies.

Consider electrification. We know that losing the internal combustion engine will be good for the planet. But, as Evans points out, a lot will change when the supporting infrastructure for gas guzzlers disappears: many repair shops will be out of a job, because most car maintenance is focused around the motor. And gas stations no longer have a purpose, so what happens to the convenience stores that they contain—and the half of America’s tobacco sales that gas stations account for?

As for self-driving cars, every company involved in the nascent industry is keen to point out that autonomous vehicles will crash less frequently than those driven by humans. But the benefits of a car that can drive itself aren't limited to moving folks from A to B: it can also go park itself somewhere usually considered too inconvenient for human passengers, ready to be beckoned when needed. That means that huge swaths of land in the hearts of cities, currently used as parking lots, could be repurposed—potentially upending the real estate market.

These are just a couple of the examples Evans provides, and there are far more to consider. He also traces out large-scale ramifications for the electricity industry, as home solar storage systems for car charging help solve the problem of peak demand; increased commute distances made possible by autonomous cars that drive faster and fender-to-fender; and huge shifts in the public transit sector as on-demand autonomous vehicles break down boundaries between cars, taxis, and buses.

But it's the combination of these outcomes that's really interesting. In an America without gas stations and inner-city parking lots, where on-demand transport rivals public transit, and car crashes are nonexistent, the urban landscape is redefined. In Europe, most cities predate cars by centuries, and were always built to be walkable. They could easily revert to type. American cities, on the other hand, have been designed around the car. That means that the way they’re used could change altogether.

“Increasingly, augmented and virtual reality are about more than gaming—companies are finding enterprise potential in the technology. The goal: to replace keyboards and flat displays with new paradigms for communication and collaboration, bringing a major shift in user engagement.”

Mixed reality elevates the potential of AR, VR, and IoT technology by combining the best of our digital and physical realities. Instead of removing users completely from the real world, or simply layering flat content on top of our immediate view, MR adds intelligence—physics, gravity, dimension, even personality—to digital content relative to the space around us. As a result, we are able to blur the lines between what is real and what is imagined while stripping away the barriers that interfere with our ability to make decisions quickly, absorb and process critical information, visualize possible scenarios before acting, or share knowledge and tasks between individuals and groups. Science fiction no longer, the future of engagement is here, and enterprises will likely be the first to embrace it.

Microsoft’s quest for a topological quantum computer

Microsoft’s quest for a topological quantum computer | numeric | Scoop.it

The race is on build a ‘universal’ quantum computer. Such a device could be programmed to speedily solve problems that classical computers cannot crack, potentially revolutionizing fields from pharmaceuticals to cryptography. Many of the world's major technology firms are taking on the challenge, but Microsoft has opted for a more tortuous route than its rivals.

IBM, Google and a number of academic labs have chosen relatively mature hardware, such as loops of superconducting wire, to make quantum bits (qubits). These are the building blocks of a quantum computer: they power its speedy calculations thanks to their ability to be in a mixture (or superposition) of ‘on’ and ‘off’ states at the same time.

Microsoft, however, is hoping to encode its qubits in a kind of quasiparticle: a particle-like object that emerges from the interactions inside matter. Some physicists are not even sure that the particular quasiparticles Microsoft are working with — called non-abelian anyons — actually exist. But the firm hopes to exploit their topological properties, which make quantum states extremely robust to outside interference, to build what are called topological quantum computers. Early theoretical work on topological states of matter won three physicists the Nobel Prize in Physics on 4 October, 2016.

The firm has been developing topological quantum computing for more than a decade and today has researchers writing software for future machines, and working with academic laboratories to craft devices.

Quantum computing closer as RMIT drives towards first quantum data bus

Quantum computing closer as RMIT drives towards first quantum data bus | numeric | Scoop.it

RMIT University researchers have trialled a quantum processor capable of routing quantum information from different locations in a critical breakthrough for quantum computing. The work opens a pathway towards the "quantum data bus", a vital component of future quantum technologies.

The research team from the Quantum Photonics Laboratory at RMIT in Melbourne, Australia, the Institute for Photonics and Nanotechnologies of the CNR in Italy and the South University of Science and Technology of China, have demonstrated for the first time the perfect state transfer of an entangled quantum bit (qubit) on an integrated photonic device.

Quantum Photonics Laboratory Director Dr Alberto Peruzzo said after more than a decade of global research in the specialised area, the RMIT results were highly anticipated. "The perfect state transfer has emerged as a promising technique for data routing in large-scale quantum computers," Peruzzo said. "The last 10 years has seen a wealth of theoretical proposals but until now it has never been experimentally realized. "Our device uses highly optimised quantum tunnelling to relocate qubits between distant sites. It's a breakthrough that has the potential to open up quantum computing in the near future."

The difference between standard computing and quantum computing is comparable to solving problems over an eternity compared to a short time. "Quantum computers promise to solve vital tasks that are currently unmanageable on today's standard computers and the need to delve deeper in this area has motivated a worldwide scientific and engineering effort to develop quantum technologies," Peruzzo said.

"It could make the critical difference for discovering new drugs, developing a perfectly secure quantum Internet and even improving facial recognition.'' Peruzzo said a key requirement for any information technology, along with processors and memories, is the ability to relocate data between locations.

Full scale quantum computers will contain millions, if not billions, of quantum bits (qubits) all interconnected, to achieve computational power undreamed of today. While today's microprocessors use data buses that route single bits of information, transferring quantum information is a far greater challenge due to the intrinsic fragility of quantum states.

"Great progress has been made in the past decade, increasing the power and complexity of quantum processors," Peruzzo said.

Robert Chapman, an RMIT PhD student working on the experiment, said the protocol they developed could be implemented in large scale quantum computing architectures, where interconnection between qubits will be essential.

Japanese man is first to receive 'reprogrammed' stem cells from another person

Japanese man is first to receive 'reprogrammed' stem cells from another person | numeric | Scoop.it

World-first transplant, used to treat macular degeneration, represents a major step forward in movement to create banks of ready-made stem cells.

On 28 March 2017, a Japanese man in his 60s became the first person to receive cells derived from induced pluripotent stem (iPS) cells donated by another person. The surgery is expected to set the path for more applications of iPS-cell technology, which offers the versatility of embryonic stem cells without their ethical taint. Banks of iPS cells from diverse donors could make stem-cell transplants more convenient to perform, while slashing costs. iPS cells are created by removing mature cells from an individual (for example, from their skin) and reprogramming these cells back to an embryonic state. They can then be coaxed into a type of cell useful for treating a disease.

In the latest procedure, performed on a man from the Hyogo prefecture of Japan, skin cells from an anonymous donor were reprogrammed into iPS cells and then turned into a type of retinal cell, which was in turn transplanted onto the retina of the patient, who has age-related macular degeneration. Physicians hope that the cells will stop the progression of the disease, which can lead to blindness.

In September 2014 at the Kobe City Medical Center General Hospital, a Japanese woman underwent a similar procedure to receive retinal cells derived from iPS cells. But these were reprogrammed from cells taken from her own skin. Cells prepared in the same way for a second patient were found to contain genetic abnormalities, and were never implanted. Cells from macular degeneration patients, who tend to be elderly, might have also accumulated genetic defects that could increase the risk of the procedure.

The team decided to redesign the study according to new regulations, and so no more participants were recruited. This month, however, the researchers reported that the Japanese woman fared well1. The introduced cells remained intact one year after surgery, and her vision had not declined, as would usually be expected with macular degeneration.

In Tuesday's procedure — performed at the same hospital and by the same surgeon, Yasuo Kurimoto — doctors used iPS cells that had been taken from a donor’s skin cells, reprogrammed and banked. Japan’s health ministry approved the study, which plans to enroll a total of five patients, on 1 February.

Personally, I'm not a fan of this decision, but it's as if they watched the classic West Wing clip and decided to roll with it. I think that the Peters projection map is better than the Mercator for most educational applications, but it isn't the "right, best, or true" map projection.  Many viral videos comparing the two love to exaggerate and say things like "The maps you use are lying to you" or "the world is nothing like you've ever seen."  Yes, Mercator maps distorts relative size, but it isn't a "wrong" map anymore than the Peters projection.  All maps have distortion and map readers need to under that all maps are a mathematical representation of the Earth.

How DNA could store all the world’s data and more

How DNA could store all the world’s data and more | numeric | Scoop.it
Modern archiving technology cannot keep up with the growing tsunami of bits. But nature may hold an answer to that problem already.

 

For Nick Goldman, the idea of encoding data in DNA started out as a joke. It was Wednesday 16 February 2011, and Goldman was at a hotel in Hamburg, Germany, talking with some of his fellow bioinformaticians about how they could afford to store the reams of genome sequences and other data the world was throwing at them. He remembers the scientists getting so frustrated by the expense and limitations of conventional computing technology that they started kidding about sci-fi alternatives. “We thought, 'What's to stop us using DNA to store information?'”

 

Then the laughter stopped. “It was a lightbulb moment,” says Goldman, a group leader at the European Bioinformatics Institute (EBI) in Hinxton, UK. True, DNA storage would be pathetically slow compared with the microsecond timescales for reading or writing bits in a silicon memory chip. It would take hours to encode data by synthesizing DNA strings with a specific pattern of bases, and still more hours to recover that information using a sequencing machine. But with DNA, a whole human genome fits into a cell that is invisible to the naked eye. For sheer density of information storage, DNA could be orders of magnitude beyond silicon — perfect for long-term archiving.

 

“We sat down in the bar with napkins and biros,” says Goldman, and started scribbling ideas: “What would you have to do to make that work?” The researchers' biggest worry was that DNA synthesis and sequencing made mistakes as often as 1 in every 100 nucleotides. This would render large-scale data storage hopelessly unreliable — unless they could find a workable error-correction scheme. Could they encode bits into base pairs in a way that would allow them to detect and undo the mistakes? “Within the course of an evening,” says Goldman, “we knew that you could.”

 

He and his EBI colleague Ewan Birney took the idea back to their labs, and two years later announced that they had successfully used DNA to encode five files, including Shakespeare's sonnets and a snippet of Martin Luther King's 'I have a dream' speech1. By then, biologist George Church and his team at Harvard University in Cambridge, Massachusetts, had unveiled an independent demonstration of DNA encoding2. But at 739 kilobytes (kB), the EBI files comprised the largest DNA archive ever produced — until July 2016, when researchers from Microsoft and the University of Washington claimed a leap to 200 megabytes (MB).

 

The latest experiment signals that interest in using DNA as a storage medium is surging far beyond genomics: the whole world is facing a data crunch. Counting everything from astronomical images and journal articles to YouTube videos, the global digital archive will hit an estimated 44 trillion gigabytes (GB) by 2020, a tenfold increase over 2013. By 2040, if everything were stored for instant access in, say, the flash memory chips used in memory sticks, the archive would consume 10–100 times the expected supply of microchip-grade silicon3.

"The same liquid we drink and that fills the oceans may be millions of years older than the solar system itself.

The clue comes in the form of something known as “heavy water.” Water, as you know, is made up of two hydrogen atoms and one oxygen atom. But some water molecules contain hydrogen’s chunky twin, deuterium. (It contains a neutron in its nucleus, whereas regular hydrogen does not.)

Deuterium-rich water is found on other planets and moons, even here on Earth, but researchers are not sure where it came from. One idea is that much of the heavy water formed in the interstellar cloud and then traveled across the solar system."
