A device that eavesdrops on the quantum whispers of atoms could form the basis of a new type of quantum computer.
Researchers have designed a tile set of DNA molecules that can carry out robust reprogrammable computations to execute six-bit algorithms and perform a variety of simple tasks. The system, which works thanks to the self-assembly of DNA strands designed to fit together in different ways while executing the algorithm, is an important milestone in constructing a universal DNA-based computing device.
The new system makes use of DNA’s ability to be programmed through the arrangement of its molecules. Each strand of DNA consists of a backbone and four types of molecules known as nucleotide bases – adenine, thymine, cytosine, and guanine (A, T, C, and G) – that can be arranged in any order. This order represents information that can be used by biological cells or, as in this case, by artificially engineered DNA molecules. The A, T, C, and G have a natural tendency to pair up with their counterparts: A base pairs with T, and C pairs with G. And a sequence of bases pairs up with a complementary sequence: ATTAGCA pairs up with TGCTAAT (in the reverse orientation), for example.

An international research team has studied how photons travel in the plane of the world’s thinnest semiconductor crystal. The results of the physicists’ work open the way to the creation of monoatomic optical transistors — components for quantum computers, potentially capable of making calculations at the speed of light.
The fine art of adding impurities to silicon wafers lies at the heart of semiconductor engineering and, with it, much of the computer industry. But this fine art isn’t yet so finely tuned that engineers can manipulate impurities down to the level of individual atoms.
As technology scales down to the nanometer size and smaller, though, the placement of individual impurities will become increasingly significant. Which makes interesting the announcement last month that scientists can now rearrange individual impurities (in this case, single phosphorous atoms) in a sheet of graphene by using electron beams to knock them around like croquet balls on a field of grass.
The finding suggests a new vanguard of single-atom electronic engineering. Says research team member Ju Li, professor of nuclear science and engineering at MIT, gone are the days when individual atoms can only be moved around mechanically—often clumsily on the tip of a scanning tunneling microscope.
The incredible power of the GPU! Next gen consoles are gonna be lit! 😍.
Half-a-century has passed since mankind first set its foot on the moon. And while NASA is preparing to send the first woman to the moon, some humans still believe that space exploration done by US-based agency NASA was nothing more than a fake moon mission.

Aired on Gadget Lab Podcast: buddy Elon Musk because it’s always fun to talk about Elon Musk and this time the man wants to put a computer in your brain this past Tuesda.
The race is on to create new ways to protect data and communications from the threat posed by super-powerful quantum computers.
Researchers found that using a computer, playing games, and participating in social activities may reduce the risk of mild cognitive impairment.
New research suggests that playing games, using a computer, and having a rich social life can keep mild cognitive impairment at bay.
Our brains go through changes as we get older, and some people may experience issues with memory, thinking, or judgment.
“Get Out of My Head!”
For now, the phrase “Get out of my head,” is a lighthearted joke uttered when someone shares the same thought as a friend or colleague. But thanks to research in telepathic communications and computer technology by a team from the University of Washington, it could become a literal directive in the future.
Or, perhaps you’ll want to invite someone into your mind to help you solve a tricky problem. After all, two (or three) heads are better than one.
Pohoiki Beach appears to be step two of Intel’s process-architecture-optimization development model. Step three, a larger integration of Loihi chips to be called Pohoiki Springs, is scheduled to debut later this year. Neuromorphic design is still in a research phase, but this and similar projects from competitors such as IBM and Samsung should break ground for eventual commoditization and commercial use.
The new Pohoiki Beach builds on the 2017 success of Intel’s Loihi NPU.
