Xanadu Photonic Quantum Chip Solves Trillions of Times Faster

Posted by in categories: internet, quantum physics, supercomputing

Canadian quantum computer company, Xanadu, has used its photonic quantum computer chip, Borealis, to solve a problem in 36 microseconds versus classical supercomputers taking 9,000 years. This is 7,884 trillion times faster. This runtime advantage is more than 50 million times larger than that of earlier photonic demonstrations.

An earlier quantum photonic computer used a static chip. The Borealis optical elements can all be readily programmed.

Decoding a key part of the cell, atom

Posted by in categories: computing, genetics, nanotechnology, nuclear energy, particle physics

Whatever you are doing, whether it is driving a car, going for a jog, or even at your laziest, eating chips and watching TV on the couch, there is an entire suite of molecular machinery inside each of your cells hard at work. That machinery, far too small to see with the naked eye or even with many microscopes, creates energy for the cell, manufactures its proteins, makes copies of its DNA, and much more.

Among those pieces of machinery, and one of the most complex, is something known as the nuclear pore complex (NPC). The NPC, which is made of more than 1,000 individual proteins, is an incredibly discriminating gatekeeper for the cell’s nucleus, the membrane-bound region inside a cell that holds that cell’s genetic material. Anything going in or out of the nucleus has to pass through the NPC on its way.

Synapse Study Explores the “Dark Matter of the Brain”

Posted by in categories: biological, chemistry, cosmology, neuroscience

They are part of the brain of almost every animal species, yet they remain usually invisible even under the electron microscope. “Electrical synapses are like the dark matter of the brain,” says Alexander Borst, director at the MPI for Biological Intelligence, in foundation (i.f). Now a team from his department has taken a closer look at this rarely explored brain component: In the brain of the fruit fly Drosophila, they were able to show that electrical synapses occur in almost all brain areas and can influence the function and stability of individual nerve cells.

Neurons communicate via synapses, small contact points at which chemical messengers transmit a stimulus from one cell to the next. We may remember this from biology class. However, that is not the whole story. In addition to the commonly known chemical synapses, there is a second, little-known type of synapse: the electrical synapse. “Electrical synapses are much rarer and are hard to detect with current methods. That’s why they have hardly been researched so far,” explains Georg Ammer, who has long been fascinated by these hidden cell connections. “In most animal brains, we therefore don’t know even basic things, such as where exactly electrical synapses occur or how they influence brain activity.”

An electrical synapse connects two neurons directly, allowing the electrical current that neurons use to communicate, to flow from one cell to the next without a detour. Except in echinoderms, this particular type of synapse occurs in the brain of every animal species studied so far. “Electrical synapses must therefore have important functions: we just do not know which ones!” says Georg Ammer.

Graphene charge-injection photodetectors with a broader detection bandwidth

Posted by in categories: materials, particle physics

Photodetectors, sensors that can detect light or other forms of electromagnetic radiation, are essential components of imaging tools, communication systems, and various other technologies on the market. These sensors work by converting photons (i.e., light particles) into electrical current.

Researchers at Zhejiang University have recently developed a new photodetector that could detect light within a broader bandwidth. Their device, presented in a paper published in Nature Electronics, could be used to develop new and more advanced imaging technologies.

“Our recent project is based on traditional charge-coupled device (CCD) and complementary metal-oxide-semiconductor (CMOS) imaging technologies,” Prof. Yang Xu, one of the researchers who carried out the study, told TechXplore. “Our novel imaging devices combining CCD’s MOS photogate for and CMOS’s independent pixel structure can significantly benefit monolithic integration, performance, and readout.”

Scientists craft living human skin for robots

Posted by in categories: materials, robotics/AI

From action heroes to villainous assassins, biohybrid robots made of both living and artificial materials have been at the center of many sci-fi fantasies, inspiring today’s robotic innovations. It’s still a long way until human-like robots walk among us in our daily lives, but scientists from Japan are bringing us one step closer by crafting living human skin on robots. The method developed, presented June 9 in the journal Matter, not only gave a robotic finger skin-like texture, but also water-repellent and self-healing functions.

“The finger looks slightly ‘sweaty’ straight out of the culture medium,” says first author Shoji Takeuchi, a professor at the University of Tokyo, Japan. “Since the finger is driven by an , it is also interesting to hear the clicking sounds of the motor in harmony with a finger that looks just like a real one.”

Researchers envision wood-derived, self-powered biosensors for wireless devices

Posted by in categories: mobile phones, privacy

Wood-derived materials can be used to harvest electrical energy from everyday movements such as walking, according to University of Toronto and University of Waterloo researchers.

In a new study recently published in Nano Energy, the team demonstrated the use of lignocellulosic nanofibrils—derived from —in a prototype self-powered device capable of sending a wireless signal to a smartphone via bluetooth.

Such devices can be used to track biometric data such as heart rate, oxygen levels or skin conductivity. The innovation could improve the performance of these devices while lowering their environmental impact.
