Computing at the speed of light: Team takes big step toward much faster computers

Posted by in categories: drones, engineering, robotics/AI, supercomputing

Circa 2015


University of Utah engineers have taken a step forward in creating the next generation of computers and mobile devices capable of speeds millions of times faster than current machines.

The Utah engineers have developed an ultracompact beamsplitter—the smallest on record—for dividing light waves into two separate channels of information. The device brings researchers closer to producing silicon photonic chips that compute and shuttle data with light instead of electrons. Electrical and computer engineering associate professor Rajesh Menon and colleagues describe their invention today in the journal Nature Photonics.

Engineers zap and unstick underwater smart glue

Posted by in categories: biotech/medical, cyborgs, engineering

With a small zap of electricity, biomedical engineers at Michigan Technological University take an underwater smart glue prototype from sticky to not in seven seconds.

Turning adhesion on and off is what makes a smart. It’s one thing to do this in the open air and quite another under water. Inspired by nature, catechols are synthetic compounds that mimic the wet-but-still-sticky proteins secreted by mussels and offer promise for smart adhesives that work in water. The technology could help with underwater glue, wound dressings, prosthetic attachments or even making car parts and in other manufacturing.

Anders Sandberg — Freeman Dyson, Galactic Megastructures, Physical Eschatology & the Fermi Paradox

Posted by in categories: alien life, bitcoin, computing, cryptocurrencies, engineering, existential risks, transhumanism

Many of you know the sad news that theoretical physicist & mathematician Freeman Dyson has passed away, so in celebration of his life and achievements, Anders Sandberg (Future of Humanity Institute) discusses Freeman Dyson’s influence on himself and others — How might advanced alien civilizations develop (and indeed perhaps our own)?
We discuss strategies for harvesting energy — star engulfing Dyson Spheres or Swarms, black hole swallowing tungsten dyson super-swarms and other galactic megastructures, we also discuss Kardashev scale civilizations (Kardashev was another great mind who we lost recently), reversible computing, birthing ideal universes to live in, Meinong’s jungle, ‘eschatological engineering’, the aestivation hypothesis, and how all this may inform strategies for thinking about the Fermi Paradox and what this might suggest about the likelihood of our civilization avoiding oblivion. though Anders is more optimistic than some about our chances of survival…

Anders Sandberg (Future of Humanity Institute in Oxford) is a seminal transhumanist thinker from way back who has contributed a vast amount of mind blowing material to futurology & philosophy in general. https://en.wikipedia.org/wiki/Anders_Sandberg

The Dutch shipbuilder Royal Huisman used an engineering process developed by the European Space Agency (ESA) for space missions in the design of the superyacht Sea Eagle II — expected to become the largest aluminum sailing yacht in the world upon delivery to its owner this Spring.


Engineering design used by the European Space Agency was used to create the largest aluminum superyacht.

Diabetes in mice cured rapidly using human stem cell strategy

Posted by in categories: biotech/medical, engineering

Researchers have converted human stem cells into insulin-producing cells and demonstrated in mice infused with such cells that blood sugar levels can be controlled and diabetes functionally cured for nine months.

The findings, from researchers at Washington University School of Medicine in St. Louis, are published online Feb. 24 in the journal Nature Biotechnology.

“These mice had very severe diabetes with blood sugar readings of more than 500 milligrams per deciliter of blood — levels that could be fatal for a person — and when we gave the mice the insulin-secreting cells, within two weeks their blood glucose levels had returned to normal and stayed that way for many months,” said principal investigator Jeffrey R. Millman, PhD, an assistant professor of medicine and of biomedical engineering at Washington University.

Cryo-chip overcomes obstacle to large-scale quantum computers

Posted by in categories: biotech/medical, engineering, quantum physics, supercomputing

QuTech has resolved a major issue on the road toward a working large-scale quantum computer. QuTech, a collaboration of TU Delft and TNO, and Intel have designed and fabricated an integrated circuit that can controlling qubits at extremely low temperatures. This paves the way for the crucial integration of qubits and their controlling electronics in the same chip. The scientists have presented their research during the ISSCC Conference in San Francisco.

Quantum computers

“This result brings us closer to a large-scale quantum computer which can solve problems that are intractable by even the most powerful supercomputers. Solutions to those problems can make a strong impact on , for instance in the fields of medicine and energy,” said team lead Fabio Sebastiano from QuTech and the Faculty of Electrical Engineering, Mathematics and Computer Science.

Correcting the jitters in quantum devices

Posted by in categories: computing, engineering, quantum physics

Labs around the world are racing to develop new computing and sensing devices that operate on the principles of quantum mechanics and could offer dramatic advantages over their classical counterparts. But these technologies still face several challenges, and one of the most significant is how to deal with “noise”—random fluctuations that can eradicate the data stored in such devices.

A new approach developed by researchers at MIT could provide a significant step forward in quantum correction. The method involves fine-tuning the system to address the kinds of noise that are the most likely, rather than casting a broad net to try to catch all possible sources of disturbance.

The analysis is described in the journal Physical Review Letters, in a paper by MIT graduate student David Layden, postdoc Mo Chen, and professor of nuclear science and engineering Paola Cappellaro.

“Reverse fuel cell” converts waste carbon to valuable products at record rates

Posted by in categories: energy, engineering

Fuel cells turn chemicals into electricity. Now, a U of T Engineering team has adapted technology from fuel cells to do the reverse: harness electricity to make valuable chemicals from waste carbon (CO2).

“For decades, talented researchers have been developing systems that convert electricity into hydrogen and back again,” says Professor Ted Sargent (ECE), one of the senior authors of a paper published today in Science. “Our innovation builds on that legacy, but by using carbon-based molecules, we can plug directly into existing hydrocarbon infrastructure.”

In a hydrogen fuel cell, hydrogen and oxygen come together on the surface of a catalyst. The chemical reaction releases electrons, which are captured by specialized materials within the fuel cell and pumped into a circuit.
