Part 1: Entrepreneur & Researcher Robert Bradbury

Posted by in categories: bioengineering, biotech/medical, computing, life extension, nanotechnology, neuroscience

This came up recently and it occurred I never posted this here. This is a lecture by Robert Bradbury, not not Ray Bradbury. I had the pleasure of exchanging a few emails with him. Unfortunately those emails are lost so I cannot share them. He was an advocate of life extension and he was a big thinker. I’ll post both vids and a link to the M-brain page. He is not with us anymore I regret to say. Ready?


Renown aging expert Robert Bradbury discusses whole genome engineering, evolution and aging and ways to defeat aging. His talk touches on many areas including nanotechnology, biology, and computer science.

Scientists create world’s first biologically powered computer chip

Posted by in categories: computing, engineering, mobile phones

The dream of melding biological and man-made machinery is now a little more real with the announcement that Columbia Engineering researchers have successfully harnessed a chemical energy-producing biological process to power a solid state CMOS integrated circuit.

According to study lead professor Ken Shepard, this is the world’s first successful effort to isolate a biological process and use it to power an integrated circuit, much like the ones we use in phones and computers.

The researchers developed the system by using an artificially created lipid bilayer membrane containing naturally occurring ion pumps, which are powered by the biological world’s “energy currency molecule,” ATP (adenosine triphosphate). ATP is the coenzyme that transfers chemical energy between living cells. It is an end product of processes such as photosynthesis and cellular respiration, and it powers the mechanical work of living systems such as cell division and muscle contraction.

Oxford team demonstrates ‘hybrid’ logic gate as work towards quantum computer continues

Posted by in categories: computing, particle physics, quantum physics

‘In a nice piece of “spin-off science” from this technological achievement, we were able to perform a “Bell test”, by first using the high-precision logic gate to generate an entangled state of the two different-species ions, then manipulating and measuring them independently. This is a test which probes the non-local nature of quantum mechanics; that is, the fact that an entangled state of two separated particles has properties that cannot be mimicked by a classical system. This was the first time such a test had been performed on two different species of atom separated by many times the atomic size.’

While Professor Lucas cautions that the so-called ‘locality loophole’ is still present in this experiment, there is no doubt the work is an important contribution to the growing body of research exploring the physics of entanglement. He says: ‘The significance of the work for trapped-ion quantum computing is that we show that quantum logic gates between different isotopic species are possible, can be driven by a relatively simple laser system, and can work with precision beyond the so-called “fault-tolerant threshold” precision of approximately 99% — the precision necessary to implement the techniques of quantum error correction, without which a quantum computer of useful size cannot be built.’

In the long term, it is likely that different atomic elements will be required, rather than different isotopes. In closely related work published in the same issue of Nature, by Ting Rei Tan et al, the NIST Ion Storage group has demonstrated a different type of quantum logic gate using ions of two different elements (beryllium and magnesium).

Scientists have built a functional ‘hybrid’ logic gate for use in quantum computers

Posted by in categories: computing, particle physics, quantum physics

As conventional computers draw ever closer to their theoretical limit, the race is on to build a machine that can truly harness the unprecedented processing power of quantum computing. And now two research teams have independently demonstrated how entangling atoms from different elements can address the problem of quantum memory errors while functioning within a logic gate framework, and also pass the all-important test of true entanglement.

Microsoft’s Latest HoloLens Is Here, and It’s Amazing

Posted by in categories: augmented reality, computing

Of all the recent advances in computing and consumer technology, This is BY FAR the one I’m most fascinated! Amazing tech.


The HoloLens headset from Microsoft is the world’s first untethered wearable that generates holograms before your eyes. It’s been nearly a year since we first strapped on a prototype, and as the tech goliath prepares to unleash a first batch of units to developers in the coming months, I was invited to check out just how far the technology has come.

Team adds to quantum computing toolkit with mixed-atom logic operations

Posted by in categories: computing, particle physics, quantum physics

Physicists at the National Institute of Standards and Technology (NIST) have added to their collection of ingredients for future quantum computers by performing logic operations—basic computing steps—with two atoms of different elements. This hybrid design could be an advantage in large computers and networks based on quantum physics.

The NIST experiment, described in the Dec. 17 issue of Nature, manipulated one magnesium and one beryllium ion (charged atom) confined in a custom trap (see photo). The scientists used two sets of laser beams to entangle the two ions—establishing a special quantum link between their properties—and to perform two types of logic operations, a controlled NOT (CNOT) gate and a SWAP gate. The same issue of Nature describes similar work with two forms of performed at the University of Oxford.

“Hybrid quantum computers allow the unique advantages of different types of quantum systems to be exploited together in a single platform,” said lead author Ting Rei Tan. “Many research groups are pursuing this general approach. Each ion species is unique, and certain ones are better suited for certain tasks such as memory storage, while others are more suited to provide interconnects for data transfer between remote systems.”

What do you call a DNA molecule that changes between high and low electrical conductance (amount of current flow)?

Answer: a molecular switch (transistor) for nanoscale computing. That’s what a team of researchers from the University of California, Davis and the University of Washington have documented in a paper published in Nature Communications Dec. 9.
