New Ultrahard Diamond Glass Synthesized Using Carbon Buckyballs

Posted by in categories: chemistry, particle physics

It is the hardest known glass with the highest thermal conductivity among all glass materials.

Carnegie’s Yingwei Fei and Lin Wang were part of an international research team that synthesized a new ultrahard form of carbon glass with a wealth of potential practical applications for devices and electronics. It is the hardest known glass with the highest thermal conductivity among all glass materials. Their findings are published in Nature.

Function follows form when it comes to understanding the properties of a material. How its atoms are chemically bonded to each other, and their resulting structural arrangement, determines a material’s physical qualities—both those that are observable by the naked eye and those that are only revealed by scientific probing.

AI must have its own goals to be truly intelligent

Posted by in categories: genetics, mathematics, robotics/AI

There are synergies between the two kinds of intelligence. The brain serves the genes by improving the organism’s capability to survive and reproduce. In exchange, evolution favors genetic mutations that improve the brain’s innate and learning capacities for each species (this is why some animals are born with the ability to walk while others learn it weeks or months later).

At the same time, the brain comes with tradeoffs. Genes lose some of their control over the behavior of the organism when they relegate their duties to the brain. Sometimes, the brain can go chasing rewards that do not serve the self-replication of the genes (e.g., addiction, suicide). Also, the behavior learned by the brain does not pass on through genes (this is why you didn’t inherit your parents’ knowledge and had to learn language, math, and sports from scratch).

As Lee writes in Birth of Intelligence, “The fact that brain functions can be modified by experience implies that genes do not fully control the brain. However, this does not mean that the brain is completely free from genes, either. If the behaviors selected by the brain prevent the self-replication of its own genes, such brains would be eliminated during evolution. Thus, the brain interacts with the genes bidirectionally.”

Ray Kurzweil — What’s the Far Future of Intelligence in the Universe?

Posted by in categories: futurism, Ray Kurzweil

Our universe has been developing for about 14 billion years, but human-level intelligence, at least on Earth, has emerged in a remarkably short period of time, measured in tens or hundreds of thousands of years. What then is the future of intelligence?

Spiderweb as inspiration for creating of one of the world’s most precise microchip sensors

Posted by in categories: cosmology, internet, nanotechnology, quantum physics, robotics/AI

A team of researchers from TU Delft managed to design one of the world’s most precise microchip sensors. The device can function at room temperature—a ‘holy grail’ for quantum technologies and sensing. Combining nanotechnology and machine learning inspired by nature’s spiderwebs, they were able to make a nanomechanical sensor vibrate in extreme isolation from everyday noise. This breakthrough, published in the Advanced Materials Rising Stars Issue, has implications for the study of gravity and dark matter as well as the fields of quantum internet, navigation and sensing.

One of the biggest challenges for studying vibrating objects at the smallest scale, like those used in sensors or quantum hardware, is how to keep ambient thermal noise from interacting with their fragile states. Quantum hardware for example is usually kept at near absolute zero (−273.15°C) temperatures, and refrigerators cost half a million euros apiece. Researchers from TU Delft created a web-shaped microchip sensor that resonates extremely well in isolation from room temperature noise. Among other applications, their discovery will make building quantum devices much more affordable.

Researchers suggest battery-powered trains could very soon be economically viable

Posted by in categories: energy, sustainability, transportation

A small team of researchers from Lawrence Berkeley National Laboratory and the University of California has found that battery-powered trains could become economical as soon as 2023. In their paper published in the journal Nature Energy, the group argues that improved battery technology and cheap, renewable energy could soon allow battery power to compete with diesel fuel to power trains. Federico Zenith with NTNU, Trondheim, has published a News & Views piece in the same journal issue outlining the reasons for converting trains to battery power and gives an overview of the work done by the team on this new effort.

Trains, as Zenith notes, haul approximately 40 percent of intercity freight in the U.S., and sending things by train is cheaper than using trucks. Most of the freight trains in the U.S. run on , he states, spewing approximately 0.6 percent of total U.S. carbon emissions. In this new effort, the researchers suggest that switching to could prevent these emissions.

Electric trains in the U.S. get their power from overhead lines—a system that is expensive and inefficient. The team suggests that batteries could provide a better option; more specifically, they claim that a single locomotive equipped with a 14-megawatt battery system would be sufficient to replace a train powered by a diesel engine. They further claim that such a locomotive could carry a train approximately 240 kilometers on a single charge. This would consume half the energy of a diesel-powered train. And if the battery is charged using a renewable resource, it would reduce the carbon footprint of an electric train to zero.

First ‘robotaxis’ enter service in Beijing

Posted by in categories: robotics/AI, transportation

It looks like a normal car but the white taxi by the kerb has nobody driving it, and communicates with customers digitally to obtain directions and take payment.

Beijing this week approved its first autonomous taxis for commercial use, bringing dozens of the so-called “robotaxis” to the streets of the Chinese capital.

The vehicles can only carry two passengers at a time and are confined to the city’s southern Yizhuang area.

Accelerated renewables-based electrification paves the way for a post-fossil future

Posted by in categories: climatology, innovation

Cost-slashing innovations are underway in the electric power sector and could give electricity the lead over fossil-based combustion fuels in the world’s energy supply by mid-century. When combined with a global carbon price, these developments can catalyze emission reductions to reach the Paris climate targets, while reducing the need for controversial negative emissions, a new study finds.

“Today, 80 percent of all energy demands for industry, mobility or heating buildings is met by burning—mostly fossil—fuels directly, and only 20 percent by electricity. Our research finds that relation can be pretty much reversed by 2050, making the easy-to-decarbonise electricity the mainstay of global energy supply,” says Gunnar Luderer, author of the new study and researcher the Potsdam Institute for Climate Impact Research. “For the longest time, fossil fuels were cheap and accessible, whilst electricity was the precious and pricier source of energy. Renewable electricity generation—especially from solar photovoltaics—has become cheaper at breath-taking speed, a pace that most climate models have so far underestimated. Over the last decade alone prices for solar electricity fell by 80 percent, and further cost reductions are expected in the future. This development has the potential to fundamentally revolutionize energy systems.

Stretchable pressure sensor could lead to better robotics, prosthetics

Posted by in categories: biotech/medical, cyborgs, robotics/AI

In the future, soft robotic hands with advanced sensors could help diagnose and care for patients or act as more lifelike prostheses.

But one roadblock to encoding soft robotic hands with human-like sensing capabilities and dexterity has been the stretchability of sensors. Although pressure sensors—needed for a robotic hand to grasp and pick up an object, or even take a pulse from a wrist—have been able to bend or stretch, their performance has been significantly affected by such movement.

Researchers at the Pritzker School of Molecular Engineering (PME) at the University of Chicago have found a way to address this issue and have designed a new pressure sensor that can be stretched up to 50 percent while maintaining almost the same sensing performance. It is also sensitive enough to sense the pressure of a small piece of paper, and it can respond to pressures almost instantaneously.

Creating deeper defense against cyber attacks

Posted by in categories: cybercrime/malcode, information science, internet

To address the growing threat of cyberattacks on industrial control systems, a KAUST team including Fouzi Harrou, Wu Wang and led by Ying Sun has developed an improved method for detecting malicious intrusions.

Internet-based are widely used to monitor and operate factories and critical infrastructure. In the past, these systems relied on expensive dedicated networks; however, moving them online has made them cheaper and easier to access. But it has also made them more vulnerable to attack, a danger that is growing alongside the increasing adoption of internet of things (IoT) technology.

Conventional security solutions such as firewalls and are not appropriate for protecting industrial control systems because of their distinct specifications. Their sheer complexity also makes it hard for even the best algorithms to pick out abnormal occurrences that might spell invasion.
