Pilotless Cargo Flights By 2025

Pilotless planes would save airlines $35bn (£27bn) a year and could lead to substantial fare cuts – if passengers were able to stomach the idea of remote-controlled flying, according to new research. The savings for carriers could be huge, said investment bank UBS, even though it may take until the middle of the century for passengers to have enough confidence to board a pilotless plane. UBS estimated that pilots cost the industry $31bn a year, plus another $3bn in training, and that fully automated planes would fly more efficiently, saving another $1bn a year in fuel.

Passengers could benefit from a reduction in ticket prices of about a tenth, the report said. “The average percentage of total cost and average benefit that could be passed onto passengers in price reduction for the US airlines is 11%,” it said, although the savings in Europe would be less, at 4% on average but rising to 8% at RyanairAircraft costs and fuel make up a much larger proportion of costs at airlines than pilot salaries, but UBS said profits at some major airlines could double if they switched to pilotless.

More than half of the 8,000 people UBS surveyed, however, said they would refuse to travel in a pilotless plane, even if fares were cut. “Some 54% of respondents said they were unlikely to take a pilotless flight, while only 17% said they would likely undertake a pilotless flight. Perhaps surprisingly, half of the respondents said that they would not buy the pilotless flight ticket even if it was cheaper,” the report said. It added, however, that younger and more educated respondents were more willing to fly on a pilotless plane. “This bodes well for the technology as the population ages,” it said.

Nanoweapons Against North Korea

Unless you’re working in the field, you probably never heard about U.S. nanoweapons. This is intentional. The United States, as well as Russia and China, are spending billions of dollars per year developing nanoweapons, but all development is secret. Even after Pravda.ru’s June 6, 2016 headline, “US nano weapon killed Venezuela’s Hugo Chavez, scientists say,” the U.S. offered no response.

Earlier this year, May 5, 2017, North Korea claimed the CIA plotted to kill Kim Jong Un using a radioactive nano poison, similar to the nanoweapon Venezuelan scientists claim the U.S. used to assassinate former Venezuelan President Hugo Chavez. All major media covered North Korea’s claim. These accusations are substantial, but are they true? Let’s address this question.

Unfortunately, until earlier this year, nanoweapons gleaned little media attention. However, in March 2017 that changed with the publication of the book, Nanoweapons: A Growing Threat to Humanity (2017 Potomac Books), which inspired two articles. On March 9, 2017, American Security Today published “Nanoweapons: A Growing Threat to Humanity – Louis A. Del Monte,” and on March 17, 2017, CNBC published “Mini-nukes and mosquito-like robot weapons being primed for future warfare.” Suddenly, the genie was out of the bottle. The CNBC article became the most popular on their website for two days following its publication and garnered 6.5K shares. Still compared to other classes of military weapons, nanoweapons remain obscure. Factually, most people never even heard the term. If you find this surprising, recall most people never heard of stealth aircraft until their highly publicized use during the first Iraq war in 1990. Today, almost everyone that reads the news knows about stealth aircraft. This may become the case with nanoweapons, but for now, it remains obscure to the public.

Given their relative obscurity, we’ll start by defining nanoweapons. A nanoweapon is any military weapon that exploits the power of nanotechnology. This, of course, begs another question: What is nanotechnology? According to the United States National Nanotechnology Initiative’s website, nano.gov, “Nanotechnology is science, engineering, and technology conducted at the nanoscale, which is about 1 to 100 nanometers.” To put this in simple terms, the diameter of a typical human hair equals 100,000 nanometers. This means nanotechnology is invisible to the naked eye or even under an optical microscope.

NanoRobots Trap Bacteria And Clean Water

The lack of clean water in many areas around the world is a persistent, major public health problem. One day, tiny robots could help address this issue by zooming around contaminated water and cleaning up disease-causing bacteria. Scientists from the Max-Planck Institute for Intelligent Systems (Germany) and  the Institute for Bioengineering of Catalonia (IBEC) report a new development toward this goal in the journal ACS Applied Materials & Interfaces.

Drinking water contaminated with pathogenic bacteria can cause serious illnesses that, in areas with spotty medical services, are potentially life-threatening without proper treatment. Water can be disinfected with chlorine or other disinfectants, but there are some hardy bacteria and other microorganisms that are hard to remove. Treating water with a combination of disinfectants or increasing their concentrations can help. But they remain in the water, and their byproducts can be harmful to human health. In recent years, researchers have been exploring the use of self-propelled micromotors to degrade and capture pollutants in water. Building on this work, Diana Vilela, Samuel Sánchez Ordóñez (IBEC) and colleagues wanted to see if they could engineer tiny robots to remove waterborne bacteria.

The team designed “two-facedspherical particles to perform the task. One face is made with magnesium, which reacts with water to produce hydrogen bubbles to propel the microbots. The other face is made out of alternating iron and gold layers topped by silver nanoparticles. Bacteria stick to the gold and are killed by the silver nanoparticles. Lab testing showed that the particles can motor around in water for 15 to 20 minutes before the magnesium is spent. And they trapped more than 80 percent of E. coli in water spiked with a high concentration of the bacteria. Then, because of the iron’s magnetic properties, the microbots are removed easily with a magnet, without leaving behind any harmful waste in the water.

Nanotechnology Spacecraft

Renowned physicist Stephen Hawking is proposing a nanotechnology spacecraft that can travel at a fifth of the speed of light. At that speed, it could reach the nearest star in 20 years and send back images of a suspected “Second Earth” within 5 years. That means if we launched it today, we would have our first look at an Earth-like planet within 25 years.

Hawking proposed a nano-spacecraft, termed “Star Chip,” at the Starmus Festival IV: Life And The Universe, Trondheim, Norway, June 18 – 23, 2017. Hawking told attendees that every time intelligent life evolves it annihilates itself with “war, disease and weapons of mass destruction.” He asserted this as the primary reason why advanced civilizations from another part of the Universe are not contacting Earth and the primary reason we need to leave the Earth. His advocates we colonize a “Second Earth.”

Scientific evidence appears to support Hawking’s claim. The SETI Institute has been listening for evidence of extraterrestrial radio signals, a sign of advanced extraterrestrial life, since 1984. To date, their efforts have been futile. SETI claims, rightly, that the universe is vast, and they are listening to only small sectors, which is much like finding a needle in a haystack.

Your browsing history may be up for sale soon

A US House committee is set to vote on whether to kill privacy rules that would prevent internet service providers (ISPs) from selling users’ web browsing histories and app usage histories to advertisers. Planned protections, proposed by the Federal Communications Commission (FCC) that would have forced ISPs to get people’s consent before hawking their data – are now at risk. Here’s why it matters.

Your web browsing patterns contain a treasure trove of data, including your health concerns, shopping habits and visits to porn sites. ISPs can find out where you bank, your political views and sexual orientation simply based on the websites you visit. The fact that you’re looking at a website at all can also reveal when you’re at home and when you’re not.

spy your dataIf you ask the ISPs, it’s about showing the user more relevant advertising. They argue that web browsing history and app usage should not count as “sensitiveinformation.
Not all ISPs want to abolish the privacy protections. A list of several smaller providers – including Monkeybrains.net, Cruzio Internet and Credo Mobile – have written to representatives to oppose the decision. “One of the cornerstones of our businesses is respecting the privacy of our customers,” they said.
How does this differ from the way Google and Facebook use our data?
It’s much harder to prevent ISPs from tracking your data. You can choose not to use Facebook or Google’s search engine, and there are lots of tools you can use to block their tracking on other parts of the web, for example EFF’s Privacy Badger.

Consumers are generally much more limited for choice of ISP, in some cases only having one option in a given geographical area. This means they can’t choose one of the ISPs pledging to protect user data.

A Brain-computer Interface To Combat The Rise of AI

Elon Musk is attempting to combat the rise of artificial intelligence (AI) with the launch of his latest venture, brain-computer interface company NeuralinkLittle is known about the startup, aside from what has been revealed in a Wall Street Journal report, but says sources have described it as “neural lace” technology that is being engineered by the company to allow humans to seamlessly communicate with technology without the need for an actual, physical interface. The company has also been registered in California as a medical research entity because Neuralink’s initial focus will be on using the described interface to help with the symptoms of chronic conditions, from epilepsy to depression. This is said to be similar to how deep brain stimulation controlled by an implant helps  Matt Eagles, who has Parkinson’s, manage his symptoms effectively. This is far from the first time Musk has shown an interest in merging man and machine. At a Tesla launch in Dubai earlier this year, the billionaire spoke about the need for humans to become cyborgs if we are to survive the rise of artificial intelligence.

Over time I think we will probably see a closer merger of biological intelligence and digital intelligence,”CNBC reported him as saying at the time. “It’s mostly about the bandwidth, the speed of the connection between your brain and the digital version of yourself, particularly output.” Transhumanism, the enhancement of humanity’s capabilities through science and technology, is already a living reality for many people, to varying degrees. Documentary-maker Rob Spence replaced one of his own eyes with a video camera in 2008; amputees are using prosthetics connected to their own nerves and controlled using electrical signals from the brain; implants are helping tetraplegics regain independence through the BrainGate project.

Former director of the United States Defense Advanced Research Projects Agency (DARPA), Arati Prabhakar, comments: “From my perspective, which embraces a wide swathe of research disciplines, it seems clear that we humans are on a path to a more symbiotic union with our machines.

NanoMachine Lifts 15 times Its Weight

Using advanced 3-D printing, Dartmouth College researchers have unlocked the key to transforming microscopic nanorings into smart materials that perform work at human-scaleNanomachines (nanocomputers) can already deliver medication and serve as computer memories at the tiny nanometer scale. By integrating a 3-D printing technique pioneered at Dartmouth’s Ke Functional Materials Group, researchers may unlock even greater potential for these mini-machines.

Up until now, harnessing the mechanical work of nanomachines has been extremely difficult. We are slowly getting closer to the point that the tiny machines can operate on a scale that we can see, touch and feel.” said Chenfeng Ke, Assistant Professor for Chemistry at Dartmouth College and principle investigator for the research.

In an example provided by Ke, the first-generation smart material lifted a dime weighing 2.268g. The coin, 15 times the weight of the that lifted it, was raised 1.6 mm– the equivalent of a human lifting a car. “Creating nanomachine-based smart material is still extraordinarily complex and we are only just beginning, but this new technique could allow the design and fabrication of complex smart devices that are currently beyond our grasp,” said Ke.

The research was published on March 22 in the online edition of Angewandte Chemie, the journal of the German Chemical Society.

Shape-shifting Molecular Robots

A research group at Tohoku University and Japan Advanced Institute of Science and Technology has developed a molecular robot consisting of biomolecules, such as DNA and protein. The molecular robot was developed by integrating molecular machines into an artificial cell membrane. It can start and stop its shape-changing function in response to a specific DNA signal.

This is the first time that a molecular robotic system has been able to recognize signals and control its shape-changing function. What this means is that molecular robots could, in the near future, function in a way similar to living organisms.

Using sophisticated biomolecules such as DNA and proteins, living organisms perform important functions. For example, white blood cells can chase bacteria by sensing chemical signals and migrating toward the target. In the field of chemistry and synthetic biology, elemental technologies for making various molecular machines, such as sensors, processors and actuators, are created using biomolecules. A molecular robot is an artificial molecular system that is built by integrating molecular machines. The researchers believe that realization of such a system could lead to a significant breakthrough – a bio-inspired robot designed on a molecular basis.

The molecular robot developed by the research group is extremely small – about one millionth of a meter – similar in size to human cells. It consists of a molecular actuator, composed of protein, and a molecular clutch, composed of DNA. The shape of the robot’s body (artificial cell membrane) can be changed by the actuator, while the transmission of the force generated by the actuator can be controlled by the molecular clutch. The research group demonstrated through experiments that the molecular robot could start and stop the shape-changing behavior in response to a specific DNA signal.

The findings were published in Science Robotics.

Drones Re-Charging Wireless While Airborne

Scientists have demonstrated a highly efficient method for wirelessly transferring power to a drone while it is flying. The breakthrough could in theory allow flying drones to stay airborne indefinitely by simply hovering over a ground support vehicle to recharge opening up new potential industrial applications.

The technology uses inductive coupling, a concept initially demonstrated by inventor Nikola Tesla over 100 years ago. Two copper coils are tuned into one another, using electronics, which enables the wireless exchange of power at a certain frequency. Scientists have been experimenting with this technology for decades, but have not been able to wirelessly power flying technology.

prodrone

Now, scientists from Imperial College London (ICL) have removed the battery from an off-the-shelf mini-drone and demonstrated that they can wirelessly transfer power to it via inductive coupling. They believe their demonstration is the first to show how this wireless charging method can be efficiently done with a flying object like a drone, potentially paving the way for wider use of the technology.

To demonstrate their approach the researchers bought an off-the-shelf quadcopter drone, around 12 centimetres in diameter, and altered its electronics and removed its battery. They made a copper foil ring, which is a receiving antennae that encircles the drone’s casing. On the ground, a transmitter device made out of a circuit board is connected to electronics and a power source, creating a magnetic field.

The drone’s electronics are tuned or calibrated at the frequency of the magnetic field. When it flies into the magnetic field an alternating current (AC) voltage is induced in the receiving antenna and the drone’s electronics convert it efficiently into a direct current (DC) voltage to power it.

First Driverless Electric Bus Line Opened In Paris

Shuttling their way to a greener city. Paris opening its first driverless buses to the public on Monday. Fully electric and fully autonomous, the ‘EZ 10‘ transports up to 10 passengers across the Seine between two main stations. The buses use laser sensors to analyse their surroundings on the road and for now they don’t have to share it with any other vehicles.

“Fewer people come on board, its slower, its electric, it doesn’t pollute and it can be stored away more easily but it will never replace a traditional bus“, says Jose Gomes, who has been driving buses here for 26 years. He’ll oversee the smooth operation of the autonomous bus.

The shuttles come as Paris faces high pollution levels. City mayor Anna Hidalgo wants to reduce the number of cars, while authorities crack down on traffic restrictions. It may be a short 130m stretch for the buses but for Paris, it’s a big step towards promoting cleaner transport.

How To Fast Manufacture NanoRobots

A team of researchers led by Biomedical Engineering Professor Sam Sia at Columbia Engineering has developed a way to manufacture microscale machines from biomaterials that can safely be implanted in the body. Working with hydrogels, which are biocompatible materials that engineers have been studying for decades, Sia has invented a new technique that stacks the soft material in layers to make devices that have three-dimensional, freely moving parts. The study, published online January 4, 2017, in Science Robotics, demonstrates a fast manufacturing method Sia calls “implantable microelectromechanical systems” (iMEMS).

By exploiting the unique mechanical properties of hydrogels, the researchers developed a “locking mechanism” for precise actuation and movement of freely moving parts, which can function as valves, manifolds, rotors, pumps, and drug delivery systems. They were able to tune the biomaterials within a wide range of mechanical and diffusive properties and to control them after implantation without a sustained power supply, such as a toxic battery. They then tested the payload delivery in a bone cancer model and found that the triggering of releases of doxorubicin from the device over 10 days showed high treatment efficacy and low toxicity, at 1/10th of the standard systemic chemotherapy dose.

implantable nanorobot

Overall, our iMEMS platform enables development of biocompatible implantable microdevices with a wide range of intricate moving components that can be wirelessly controlled on demand and solves issues of device powering and biocompatibility,” says Sia, also a member of the Data Science Institute. “We’re really excited about this because we’ve been able to connect the world of biomaterials with that of complex, elaborate medical devices.  Our platform has a large number of potential applications, including the drug delivery system demonstrated in our paper which is linked to providing tailored drug doses for precision medicine.”

Robotic Sommelier Blends The Wine That Matches Your Personal Taste

It’s a device that may have wine aficionados spluttering into their claret. Vinfusion is a robotic sommelier that helps you blend a glass of wine to your specific taste. It’s pre-loaded with four distinct base wines that can be mixed together into hundreds of new flavour combinations.

wineCLICK ON THE IMAGE TO ENJOY THE VIDEO

We took about 30-odd wines into the lab and analysed the chemical profile of those individual wines… we narrowed it down to four base wines; these are a Chilean Pinot Noir, a Chilean Merlot, an Australian Shiraz and a French sweet wine which is a Muscat. And we chose these wines to represent the extremes of the flavour space that we developed,” says Sajith Wimalaratne, Manager at Cambridge Consultants. Using simple terms like full-bodied or light, and dry or sweet the user simply adjusts the parameters on a sliding scale. Vinfusion also makes recommendations based on the wine you’ve created.

I’m going to blend my own wine. So I’m going to have quite a full-bodied wine, pretty soft and fairly sweet. And it says that this wine is similar to a ruby port. And now I’m going to blend this wine; so you can see we’ve got four wines blending in the chamber here, they’re coming in the top and they’re also being aerated to open up the bouquet of the wine, just as you would open a red wine for a while before you drink it.” adds Andrew Stratton, fluids engineer at Cambridge Consultants.

The wine dispensed – while certainly quaffable – would be unlikely to pass muster with serious wine lovers. The makers deliberately chose base wines priced around the 10-dollars the average consumer spend on a bottle.  “Wine is a complex beverage. And a lot of people just tend to stick to one or two that they know. But what we wanted to do was actually make this amazing range of wines out there, and make it more accessible to the consumer,” comments Sajith Wimalaratne.   Winemaking is steeped in history, largely defying technological interference. Vinfusion could, in theory, be loaded with finer wines producing a higher quality beverage. For wine snobs, however, any Vinfusion vintage might just be too unpalatable.
