Transhumanism Is Tempting—Until You Remember Inspector Gadget

Posted by in categories: biotech/medical, computing, food, transhumanism

It’s comforting to think of the body as a machine we can trick out. It helps us ignore the strange fleshy aches that come with having a meat cage. It makes a fickle system—one we truly don’t understand—feel conquerable. To admit that the body (and mind that sits within it) might be far more complex than our most delicate, intricate inventions endangers all kinds of things: the medical industrial complex, the wellness industry, countless startups. But it might also open up new doors for better relationships with our bodies too: Disability scholars have long argued that the way we see bodies as “fixable” ultimately serves to further marginalize people who will never have the “standard operating system,” no matter how many times their parts are replaced or tinkered with.


Tech gurus are obsessed with treating bodies like machines—something a 30-year-old cartoon about a tricked-out detective suggests won’t work.

Study investigates how spin-orbit interaction protects Majorana nanowires

Posted by in categories: computing, nanotechnology, quantum physics

Researchers at Delft University of Technology have recently carried out a study investigating spin-orbit interaction in Majorana nanowires. Their study, published in Physical Review Letters, is the first to clearly show the mechanism that enables the creation of the elusive Majorana particle, which could become the building block of a more stable type of quantum computer.

“Our research is aimed at experimental verification of the theoretically proposed Majorana zero-mode,” Jouri Bommer, one of the researchers who carried out the study, told Phys.org via email. “This particle, which is its own antiparticle, is of particular interest, because it is predicted to be useful for developing a topological computer.”

Quantum computing is a promising area of computer science that explores the use of quantum-mechanical phenomena and quantum states to store information and solve computational problems. In the future, quantum computers could tackle problems that traditional computing methods are unable to solve, for instance enabling the computational and deterministic design of new drugs and molecules.

Quantum computing boost from vapour stabilising technique

Posted by in categories: biotech/medical, computing, nanotechnology, quantum physics

A technique to stabilise alkali metal vapour density using gold nanoparticles, so electrons can be accessed for applications including quantum computing, atom cooling and precision measurements, has been patented by scientists at the University of Bath.

Alkali metal vapours, including lithium, sodium, potassium, rubidium and caesium, allow scientists to access individual electrons, due to the presence of a single electron in the outer ‘shell’ of .

This has for a range of applications, including logic operations, storage and sensing in , as well as in ultra-precise time measurements with atomic clocks, or in medical diagnostics including cardiograms and encephalograms.

Production of more than 250,000 chips embedded within fibers in less than a year

Posted by in categories: biotech/medical, computing

In the summer of 2018, a team led by MIT researchers reported in the journal Nature that they had successfully embedded electronic devices into fibers that could be used in fabrics or composite products like clothing, airplane wings, or even wound dressings. The advance could allow fabrics or composites to sense their environment, communicate, store and convert energy, and more.

Research breakthroughs typically take years to make it into final products—if they reach that point at all. This particular research, however, is following a dramatically different path.

By the time the unique fiber advance was unveiled last summer, members of Advanced Functional Fabrics of America (AFFOA), a not-for-profit near MIT, had already developed ways to increase the throughput and overall reliability of the process. And, staff at Inman Mills in South Carolina had established a method to weave the advanced using a conventional, industrial manufacturing-scale loom to create fabrics that can use light to both broadcast and receive information.

The geometry of an electron determined for the first time

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

Physicists at the University of Basel have shown for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published in Physical Review Letters and the related theory in Physical Review B.

The spin of an electron is a promising candidate for use as the smallest information unit (qubit) of a computer. Controlling and switching this spin or coupling it with other spins is a challenge on which numerous research groups worldwide are working. The stability of a single spin and the entanglement of various spins depends, among other things, on the geometry of the —which previously had been impossible to determine experimentally.
