We present a detection scheme to search for QCD axion dark matter, that is based on a direct interaction between axions and electrons explicitly predicted by DFSZ axion models. The local axion dark matter field shall drive transitions between Zeeman-split atomic levels separated by the axion rest mass energy m a.

C.
2. Axion-related excitations are then detected with an upconversion scheme involving a pump laser that converts the absorbed axion energy (~hundreds of μeV) to visible or infrared photons, where single photon detection is an established technique. The proposed scheme involves rare-earth ions doped into solid-state crystalline materials, and the optical transitions take place between energy levels of 4f.

Forget Google Search and Fuchsia. Researchers from Google, Stanford, Princeton, and other universities might have made a computer discovery so big we can’t fully comprehend it yet. Even Google researchers aren’t entirely sure that their time crystal discovery is valid. But if it turns out to be accurate, then Google might be one of the first companies to give the world a crucial technological advancement for the future. Time crystals will be an essential building block in quantum computers, the kind of computers that can solve complex problems with incredible speed and power technologies that aren’t even invented.

What is a quantum computer?

Google isn’t the only company building quantum computers, and these types of machines keep popping up in the news with regularity. Quantum computers won’t reach your phone, and they’re not going to play games. Even if they did, Nintendo will totally ignore the latest computer technology when designing future consoles.

Imagining how the dimension of mobility will evolve in the next few years, Haochen gives his imagination wings in the shape of this firefly-inspired Husqvarna Devil S Concept bike.

More often than not, motorbikes are tagged as unsafe since they expose the rider’s body to high-speed dangers in case of an accident. Two-wheelers typically have a very open stance that attracts the young generation and adds to the adrenaline rush. More than anything, the ride should be stylish and match the fashion statement of the young crowd. This inspired Haochen (Wenson) Wei to design a motorbike with a very stylish character and a safe design that’s radically different from what bikes are perceived to be.

The news we like: “In five to 10 years time from now, we’ll have a new, special kind of drugs: longevity drugs. And unlike today’s medication, which always focused on one disease, this kind of drug will will give us an opportunity to influence aging as a whole and a very fatalistic way, working on healthspan, not only on lifespan… it’s very likely that this new drug will be developed with the help of artificial intelligence, which will compress drug development cycle by two or three times from what they are today.”

Ahead of the launch of his new book Growing Young, Sergey Young joins us for a video interview to discuss longevity horizons, personal health strategies and disruptive tech – and how we are moving towards radically extending our lifespan and healthspan.

Sergey Young, the longevity investor and founder of the Longevity Vision Fund is on a mission to extend healthy lifespans of at least one billion people. His new book, Growing Young, is released on 24th August and is already rising up the Amazon charts.

Over the years, deep learning has required an ever-growing number of these multiply-and-accumulate operations. Consider LeNet, a pioneering deep neural network, designed to do image classification. In 1998 it was shown to outperform other machine techniques for recognizing handwritten letters and numerals. But by 2012 AlexNet, a neural network that crunched through about 1600 times as many multiply-and-accumulate operations as LeNet, was able to recognize thousands of different types of objects in images.

Advancing from LeNet’s initial success to AlexNet required almost 11 doublings of computing performance. During the 14 years that took, Moore’s law provided much of that increase. The challenge has been to keep this trend going now that Moore’s law is running out of steam. The usual solution is simply to throw more computing resources—along with time, money, and energy—at the problem.

As a result, training today’s large neural networks often has a significant environmental footprint. One 2019 study found, for example, that training a certain deep neural network for natural-language processing produced five times the CO₂ emissions typically associated with driving an automobile over its lifetime.

Particle accelerators are hugely important in the study of the matter of the Universe, but the ones we think of tend to be gigantic instruments – surrounding cities in some cases. Now scientists have made a much smaller version to power an advanced laser, a setup that could be just as useful as its larger counterparts.

The particle accelerator in question is a plasma wakefield accelerator, which generates short and intense bursts of electrons, and the laser it’s powering is what’s known as a free-electron laser (FEL), which uses its light to analyze atoms, molecules, and condensed matter in incredibly high resolutions.

While this scenario has been tried before, the resulting laser light hasn’t been intense enough to be useful at smaller scales. Here, the researchers were able to keep the setup enclosed in few normal-sized rooms while amplifying the final electron beam produced by the laser, increasing the intensity by 100 times in the last step of the process.

“I am used to being harassed online. But this was different,” she added. “It was as if someone had entered my home, my bedroom, my bathroom. I felt so unsafe and traumatized.”

Oueiss is one of several high-profile female journalists and activists who have allegedly been targeted and harassed by authoritarian regimes in the Middle East through hack-and-leak attacks using the Pegasus spyware, created by Israeli surveillance technology company NSO Group. The spyware transforms a phone into a surveillance device, activating microphones and cameras and exporting files without a user knowing.

Launching satellites is an expensive business — at least for now. But satellites are necessary in astronomy for one major reason — they get telescopes above the atmosphere.
