Future chips may feature watercooling integrated into the silicon.

TSMC is in the process of testing and designing water cooling delivery straight to the heart of your future chips — a mandatory exploration in wake of vertically-integrated silicon.

To the moon — and beyond.

A new partnership just announced by NASA makes it official that the space agency is very much in the business of getting back to the moon.

Many people with rheumatoid arthritis, or RA, report having trouble thinking clearly, problems with memory, and difficulty concentrating.

These symptoms, known as brain fog, are widespread in people with chronic inflammatory conditions, including RA, Sjogren’s syndrome, and multiple sclerosis.

A RIFF on what country is really about.

China currently has one of the most expansive and impressive high-speed rail networks on Earth, and they aren’t showing signs of slowing. As their network reaches the far corners of their nation, Beijing could be setting its eyes on what lies beyond – far, far beyond.

According to reports, China wishes to build a high-speed, 13000-kilometer (8078-mile) train that travels from mainland China, up through Siberia in Eastern Russia, under the sea through the Bering Strait into Alaska, across the rocky peaks of Canada’s Yukon and British Columbia, and into the USA. Once constructed, they have could further extend their international bullet train into every corner of the US.

The price of such an outlandish proposal? A cool $200 billion. A price tag so high, even the likes of Jeff Bezos probably couldn’t reach it.

A team of researchers affiliated with multiple institutions in China, working at the University of Science and Technology of China, has achieved another milestone in the development of a usable quantum computer. The group has written a paper describing its latest efforts and have uploaded it to the arXiv preprint server.

Back in 2019, a team at Google announced that they had achieved “quantum supremacy” with their Sycamore machine—a 54 qubit processor that carried out a calculation that would have taken a traditional computer approximately 10000 years to complete. But that achievement was soon surpassed by other teams from Honeywell and a team in China. The team in China used a different technique, one that involved the use of photonic qubits—but it was also a one-trick pony. In this new effort, the new team in China, which has been led by Jian-Wei Pan, who also led the prior team at the University of Science and Technology has achieved another milestone.

The new effort was conducted with a 2D programable computer called Zuchongzhi—one equipped to run with 66 qubits. In their demonstration, the researchers used only 56 of those qubits to tackle a well-known computer problem—sampling the output distribution of random quantum circuits. The task requires a variety of computer abilities that involve mathematical analysis, matrix theory, the complexity of certain computations and probability theory—a task approximately 100 times more challenging than the one carried out by Sycamore just two years ago. Prior research has suggested the task set before the Chinese machine would take a conventional computer approximately eight years to complete. Zuchongzhi completed the task in less than an hour and a half. The achievement by the team showed that the Zuchongzhi machine is capable of tackling more than just one kind of task.

Richard Branson has finally launched to the edge of space aboard his Virgin Galactic space plane, a flight more than 15 years in the making. The billionaire has narrowly become the first person to fly on a spacecraft of their own making, beating Blue Origin founder Jeff Bezos by a matter of days.

Thanks to recent breakthroughs, the insides of our refrigerators could work very differently in the coming years. Scientists at GE are perfecting a method of transferring heat that uses magnets to achieve temperatures cold enough to freeze water.

In 2015, after 85 years of searching, researchers confirmed the existence of a massless particle called the Weyl fermion. With the unique ability to behave as both matter and anti-matter inside a crystal, this quasiparticle is like an electron with no mass. The story begun in 1928 when Dirac proposed an equation for the foundational unification of quantum mechanics and special relativity in describing the nature of the electron. This new equation suggested three distinct forms of relativistic particles: the Dirac, the Majorana, and the Weyl fermions. And recently, an analog of Weyl fermions has been discovered in certain electronic materials exhibiting a strong spin orbit coupling and topological behavior. Just as Dirac fermions emerge as signatures of topological insulators, in certain types of semimetals, electrons can behave like Weyl fermions.

These Weyl fermions are what can be called quasiparticles, which means they can only exist in a solid such as a crystal, and not as standalone particles. However, as complex as quasiparticles sound, their behavior is actually much simpler than that of fundamental particles, because their properties allow them to shrug off the same forces that knock their counterparts around. This discovery of Weyl fermions is huge, not just because there is finally a proof that these elusive particles exist, but because it paves the way for far more efficient electronics, and new types of quantum computing. Weyl fermions could be used to solve the traffic jams with electrons in electronics. In fact, Weyl electrons can carry charges at least 1000 times faster than electrons in ordinary semiconductors, and twice as fast as inside graphene. This could lead to a whole new type of electronics called ‘Weyltronics’.
