Researchers at École Polytechnique Fédérale de Lausanne (EPFL) and the Hitachi Cambridge Laboratory have recently designed an integrated circuit (IC) that integrates silicon quantum dots with conventional readout electronics. This chip, introduced in a paper published in Nature Electronics, is based on a 40-nm cryogenic complementary metal-oxide semiconductor (CMOS) technology that is readily and commercially available.

“Our recent paper builds on the expertise of the two groups involved,” Andrea Ruffino, one of the researchers at EPFL who carried out the study, told TechXplore. “The goal of our group was to build cryogenic (Bi)CMOS for readout and control of quantum computers, to be co-packaged or co-integrated in the final stage with silicon quantum processors. On the other hand, the team at the Hitachi Cambridge Laboratory have been studying silicon for many years.”

Ruffino and his colleagues at EPFL joined forces with the team at the Hitachi Cambridge Laboratory with the common goal of uniting classical circuits and quantum devices on a . Their paper builds on some of their previous efforts, including the proposal of cryogenic CMOS ICs for quantum computing, as well as the realization of fast-sensing and time-multiplexed sensing of silicon quantum devices.

Under pressure to hit fourth-quarter sales goals while coping with widespread semiconductor shortages, Tesla decided to remove one of the two electronic control units that are normally included in the steering racks of some made-in-China Model 3 and Model Y cars, according to two employees and internal correspondence seen by CNBC.

Tesla did not disclose the exclusion, which has already affected tens of thousands of vehicles being shipped to customers in China, Australia, the U.K., Germany and other parts of Europe. It was not immediately clear whether Tesla would make similar changes to cars manufactured in or shipped to the U.S.

For children suffering from rare diseases, it usually takes years to receive a diagnosis. This “diagnostic odyssey” is filled with multiple referrals and a barrage of tests, seeking to uncover the root cause behind mysterious and debilitating symptoms.

A new speed record in DNA sequencing may soon help families more quickly find answers to difficult and life-altering questions.

In just 7 hours, 18 minutes, a team of researchers at Stanford Medicine went from collecting a blood sample to offering a disease diagnosis. This unprecedented turnaround time is the result of ultra-rapid DNA sequencing technology paired with massive cloud storage and computing. This improved method of diagnosing diseases allows researchers to discover previously undocumented sources of genetic diseases, shining new light on the 6 billion letters in the human genome.

Neuralink, the startup cofounded and run by Elon Musk that hopes to implant computer chips in people’s brains, may have misled federal securities regulators about the billionaire entrepreneur’s role at the company.

That’s according to government documents and Fortune interviews with securities lawyers and a half-dozen former employees of the company. The employees mostly spoke anonymously out of concern for violating nondisclosure agreements and possible retaliation from Musk.

The episode involves a 2018 letter in which an attorney representing Neuralink downplayed Musk’s leadership role at the company in a letter to the Securities and Exchange Commission. The attorney’s characterization contradicts former employees’ accounts, which depict Musk as very much in charge. Neuralink and the attorney involved in the filing did not respond to requests for comment. lawyer for Neuralink told the SEC that Musk had “no executive or management role” at the company. Former employees say that’s far from the truth.

ASUS Thor PSU won’t supply 600W of power through PCIe Gen5 connector ASUS’s first PCIe Gen5 power supplies won’t be 100% compliant with the new standard.

Earlier this week it was discovered that the ASUS 12-pin cable which is supposedly the Gen5 Ready, is actually the same cable that NVIDIA ships for its GeForce RTX 30 Founders Edition graphics cards. However, there is a small twist to this story.

It appears that we might finally know the difference between the PCIe Gen5 12-pin power cable and the 12+4-pin version. The latter is the full spec cable offering 12 pins alongside special 4 data signal paths. Those data pins are required to be fully compliant with the PCI-SIG’s “12VHPWR High Power Connector (H+)” standard, the supposed new high-power connector for next-gen GPUs.

In order to supply more than 450W of power, the cable must have one of those signals grounded. Since ASUS Thor PSUs only have 12-pin cable and the company has confirmed earlier it ‘pipes up to 600W of power’, then this signal must have been internally grounded.

Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have gained insight into a fundamental process found throughout the universe. They discovered that the magnetic fields threading through plasma, the charged state of matter composed of free electrons and atomic nuclei, can affect the coming together and violent snapping apart of the plasma’s magnetic field lines. This insight could help scientists predict the occurrence of coronal mass ejections, enormous burps of plasma from the sun that could threaten satellites and electrical grids on Earth.

The scientists focused on the role of guide fields, magnetic fields threading through blobs, or chunks, known as plasmoids. The guide fields add rigidity to the system and ultimately affect the ratio of large plasmoids to small ones and help determine how much reconnection occurs.

Plasmoid reconnection resembles the that occurs in smart phones or in high-powered computers that model the weather. During this computing, many processors are calculating simultaneously and making the overall calculation rate quicker. Similarly, plasmoids speed up the overall rate of reconnection by making it occur in many places at once.
