During a recent United Nations meeting about emerging global risks, political representatives from around the world were warned about the threats posed by artificial intelligence and other future technologies.

The event, organized by Georgia’s UN representatives and the UN Interregional Crime and Justice Research Institute (UNICRI), was set up to foster discussion about the national and international security risks posed by new technologies, including chemical, biological, radiological, and nuclear (CBRN) materials.

“The world is facing some huge problems. There’s a lot of talk about how to solve them. But talk doesn’t reduce pollution, or grow food, or heal the sick. That takes doing. This film is the story about a group of doers, the elegantly simple inventions they have made to change the lives of billions of people, and the unconventional billionaire spearheading the project.”

A few years ago, researchers created the world’s lightest metal for Boeing, and now the airline has shown it off for the first time in this new video. Called microlattice, the material is 100 times lighter than styrofoam but is as rigid as metal, which means that it has some pretty exciting applications — not limited to being able to balance on top of a dandelion.

Microlattice was inspired by the structure of our bones, which are very rigid on the outside but mostly hollow on the inside, which means they can’t be easily crushed, but are lightweight enough for us to carry around all day. The new Boeing metal mimics this, and despite its rigid exterior, it has a 3D open-cellular polymer structure, which means its structure is 99.99 percent air.

Professor Nick Bostrom briefed political representatives from around the world on the national and international security risks posed by artificial intelligence and other future technologies at a UN event last week.

Professor Bostrom, Director of the Future of Humanity Institute, Oxford Martin School, was invited to speak at a special side event examining the challenges posed by chemical, biological, radiological and nuclear (CBRN) materials and weapons, held during the UN’s 2015 General Assembly meeting.

The event was organised by Georgia’s UN representatives, in collaboration with the United Nations Interregional Crime and Justice Research Institute (UNICRI), with the aim of understanding the implications of new technologies, ensuring responsible development and mitigating against misuse.

A team of scientists from the University of Chicago and the Pennsylvania State University have accidentally discovered a new way of using light to draw and erase quantum-mechanical circuits in a unique class of materials called topological insulators.

In contrast to using advanced nanofabrication facilities based on chemical processing of materials, this flexible technique allows for rewritable ‘optical fabrication’ of devices. This finding is likely to spawn new developments in emerging technologies such as low-power electronics based on the spin of electrons or ultrafast quantum computers.

The research is published today in the American Association for the Advancement of Science’s new online journal Science Advances, where it is featured on the journal’s front page.

1) A heart of foam could replace your own. Existing artificial hearts have multiple moving parts, which increases the chance of failure, but this new device is just a single piece of material. Researchers inspired by soft robots have built a pumping artificial heart that could one day replace the real deal.
The team of Bioengineers at Cornell University build their robots out of a solid, plastic foam, which naturally has an interconnected network of tubes to let air flow – just as our muscles are permeated by blood vessels. A solid coating of plastic seals everything inside like a skin.

For decades, researchers have been trying to build a computer that harnesses the enormous potential of quantum mechanics. Now engineers from the University of New South Wales (UNSW) in Australia have overcome the final hurdle, by creating a quantum logic gate in silicon — the same material that today’s computer chips are made from.

The newly developed device allows two quantum bits — or qubits — to communicate and perform calculations together, which is a crucial requirement for quantum computers. Even better, the researchers have also worked out how to scale the technology up to millions of qubits, which means they now have the ability to build the world’s first quantum processor chip and, eventually, the first silicon-based quantum computer.

Physicists have developed a method to synthesise a unique and novel type of material which resembles a graphene nanoribbon but in molecular form. This material could be important for the further development of organic solar cells.

Following Moore’s law is getting harder and harder, especially as existing components reach their physical size limitations. Parts like silicon transistor contacts — the “valves” within a transistor that allow electrons to flow — simply can’t be shrunken any further. However, IBM announced a major engineering achievement on Thursday that could revolutionize how computers operate: they’ve figured out how to swap out the silicon transistor contacts for smaller, more efficient, carbon nanotubes.

The problem engineers are facing is that the smaller silicon transistor contacts get, the higher their electrical resistance becomes. There comes a point where the components simply get too small to conduct electrons efficiently. Silicon has reached that point. But that’s where the carbon nanotubes come in. These structures measure less than 10 nanometers in diameter — that’s less than half the size of today’s smallest silicon transistor contact. IBM actually had to devise a new means of attaching these tiny components. Known as an “end-bonded contact scheme” the 10 nm electrical leads are chemically bonded to the metal substructure. Replacing these contacts with carbon nanotubes won’t just allow for computers to crunch more data, faster. This breakthrough ensures that they’ll continue to shrink, following Moore’s Law, for several iterations beyond what silicon components are capable of.

“These chip innovations are necessary to meet the emerging demands of cloud computing, Internet of Things and Big Data systems,” Dario Gil, vice president of Science & Technology at IBM Research, said in a statement. “As technology nears the physical limits of silicon, new materials and circuit architectures must be ready to deliver the advanced technologies that will drive the Cognitive Computing era. This breakthrough shows that computer chips made of carbon nanotubes will be able to power systems of the future sooner than the industry expected.” The study will be formally published October 2nd, in the journal Science. This breakthrough follows a number of other recent minimization milestones including transistors that are only 3-atoms thick or constructed from a single atom.
