World’s First Battery-Free Bluetooth Chip Pulls Power from the Air

Posted by in categories: computing, internet

“Without batteries or other high-cost components,” he continued, “tags have unlimited power and lifespan, so [they] can be embedded inside of products that were previously unconnected to the Internet of Things.”

Asteroid Research Points to Planetary Defense Issues

Posted by in categories: asteroid/comet impacts, computing, existential risks

Not as easy as the movies show. Say it isn’t so.


Incoming asteroids may be harder to break than scientists previously thought, finds a Johns Hopkins study that used a new understanding of rock fracture and a new computer modeling method to simulate asteroid collisions.

The findings, to be published in the March 15 print issue of Icarus, can aid in the creation of asteroid impact and deflection strategies, increase understanding of solar system formation, and help design asteroid mining efforts.

Researchers harness mysterious Casimir force for tiny devices

Posted by in categories: computing, quantum physics

Circa 2017


Getting something from nothing sounds like a good deal, so for years scientists have been trying to exploit the tiny amount of energy that arises when objects are brought very close together. It’s a source of energy so obscure it was once derided as a fanciful source of “perpetual motion.” Now, a research team including Princeton scientists has found a way to harness a mysterious force of repulsion, which is one aspect of that force.

This energy, predicted seven decades ago by the Dutch scientist Hendrik Casimir, arises from quantum effects and can be seen experimentally by placing two opposing plates very close to each other in a vacuum. At close range, the plates repel each other, which could be useful to certain technologies. Until recently, however, harnessing this “Casimir force” to do anything useful seemed impossible.

Remembering ENIAC, and the Women Who Programmed It

Posted by in category: computing

ENIAC was the world’s first electronic digital computer, and though it was glossed over in the history books, it was programmed by a team of six women. Remembering their contributions could inspire young women looking to break into the male-dominated tech industry.

Momo Is as Real as We’ve Made Her

Posted by in category: computing

In the world of social media, this is just the most recent panic over children’s time on places like Youtube. however, it’s important to note that many of these things ARE just hoaxes. As the article mentions, this hoax plays on the guilt some parents have over how much time their children spend on computer screens.


The real “Momo Challenge” is the terror of parenting in the age of YouTube. Here’s the truth of what we know.

Quantum computing: Testing qubits has been put in a faster lane

Posted by in categories: chemistry, computing, finance, quantum physics, sustainability

A way to speed up quantum computer tech progress has arrived from Intel. If you are interested in following the waves and advances in quantum computing, then get familiar with this word trio: Cryogenic Wafer Prober. Before their design, the electrical characterization of qubits was slower than with traditional transistors. Even small subsets of data might take days to collect.

Drug development. Chemistry. Climate change. Financial modeling. Scientists in all areas look forward to more advancements to push quantum computers to the frontlines. Speeding progress could also mean speeding up advancements in science and industry.

“Quantum computing, in essence, is the ultimate in , with the potential to tackle problems conventional computers can’t handle,” said Intel.

Prospects for Bioinspired Single-Photon Detection Using Nanotube-Chromophore Hybrids

Posted by in categories: computing, cyborgs, nanotechnology, quantum physics

The human eye is an exquisite photodetection system with the ability to detect single photons. The process of vision is initiated by single-photon absorption in the molecule retinal, triggering a cascade of complex chemical processes that eventually lead to the generation of an electrical impulse. Here, we analyze the single-photon detection prospects for an architecture inspired by the human eye: field-effect transistors employing carbon nanotubes functionalized with chromophores. We employ non-equilibrium quantum transport simulations of realistic devices to reveal device response upon absorption of a single photon. We establish the parameters that determine the strength of the response such as the magnitude and orientation of molecular dipole(s), as well as the arrangements of chromophores on carbon nanotubes. Moreover, we show that functionalization of a single nanotube with multiple chromophores allows for number resolution, whereby the number of photons in an incoming light packet can be determined. Finally, we assess the performance prospects by calculating the dark count rate, and we identify the most promising architectures and regimes of operation.
