Raptor Lake Refresh processors are supposedly set to arrive in October, so we’ve not got long to wait — with Meteor Lake laptop chips also due in Q4.

The idea of solar energy being transmitted from space is not a new one. In 1968, a NASA engineer named Peter Glaser produced the first concept design for a solar-powered satellite. But only now, 55 years later, does it appear scientists have actually carried out a successful experiment. A team of researchers from Caltech announced on Thursday that their space-borne prototype, called the Space Solar Power Demonstrator (SSPD-1), had collected sunlight, converted it into electricity and beamed it to microwave receivers installed on a rooftop on Caltech’s Pasadena campus. The experiment also proves that the setup, which launched on January 3, is capable of surviving the trip to space, along with the harsh environment of space itself.
“To the best of our knowledge, no one has ever demonstrated wireless energy transfer in space even with expensive rigid structures. We are doing it with flexible lightweight structures and with our own integrated circuits. This is a first,” said Ali Hajimiri, professor of electrical engineering and medical engineering and co-director of Caltech’s Space Solar Power Project (SSPP), in a press release published on Thursday.
The experiment — known in full as Microwave Array for Power-transfer Low-orbit Experiment (or MAPLE for short) — is one of three research projects being carried out aboard the SSPD-1. The effort involved two separate receiver arrays and lightweight microwave transmitters with custom chips, according to Caltech. In its press release, the team added that the transmission setup was designed to minimize the amount of fuel needed to send them to space, and that the design also needed to be flexible enough so that the transmitters could be folded up onto a rocket.
Penn State researchers have discovered a protein found naturally in a bacterium (Hansschlegelia quercus) isolated from English oak buds exhibits strong capabilities to differentiate between rare earths. Harnessing its power could revolutionize the entire tech sector by fundamentally changing how critical minerals like rare earths are harvested and purified. Image Credit: Penn State. Creative Commons
The discovery is important because rare earth elements, like neodymium and dysprosium, are critical components to almost all modern technologies, from smartphones to hard drives, but they are notoriously hard to separate from the Earth’s crust and from one another.
By figuring out how this molecular handshake works at the atomic level, the researchers have found a way to separate these similar metals from one another quickly, efficiently, and under normal room temperature conditions. This strategy could lead to more efficient, greener mining and recycling practices for the entire tech sector, the researchers state. Related: U.S. Crude Trading At Big Discount To Dubai Oil.
WROCLAW, Poland/STOCKHOLM, June 16 (Reuters) — Intel (INTC.O) plans to invest up to $4.6 billion in a new semiconductor assembly and test facility near Wrocław, Poland, as part of a multi-billion-dollar investment drive across Europe to build chip capacity, it said on Friday.
The U.S. chipmaker last year announced plans to build a big chip complex in Germany along with facilities in Ireland and France as it seeks to benefit from European Commission’s eased funding rules and subsidies as the EU looks to cut its dependence on U.S. and Asian supply.
The facility in Poland will employ 2,000 workers and create several thousand additional jobs during the construction phase and hiring by suppliers, the company said in a statement.
Non-invasive methods, such as EEG and fNIRS, offer safer alternatives for BCI applications but must overcome obstacles related to signal quality and specificity.
The brain is regarded as one of the most complex known structures in the universe. It has billions of neurons, trillions of connections, and multiple levels ranging from cellular to molecular and synaptic. But the biggest challenge is that the brain is difficult to access.
“The brain is encased in a thick bone,” said Kinney, “and if you try to access, poke, or prod it, it will get really upset and hemorrhage, and delicate neurons will die.”
Nevertheless, Kinney said progress is being made on various fronts, particularly in the field of recording brain activity, which is good news for those trying to build brain-like computers.
By using error mitigation, IBM scientists believe they’ve worked around the quantum noise that plagues quantum processors.
The 12-qubit device will go out to a few academic research labs.
Intel does a lot of things, but it’s mostly noted for making and shipping a lot of processors, many of which have been named after bodies of water. So, saying that the company is set to start sending out a processor called Tunnel Falls would seem unsurprising if it weren’t for some key details. Among them: The processor’s functional units are qubits, and you shouldn’t expect to be able to pick one up on New Egg. Ever.
Tunnel Falls appears to be named after a waterfall near Intel’s Oregon facility, where the company’s quantum research team does much of its work. It’s a 12-qubit chip, which places it well behind the qubit count of many of Intel’s competitors—all of which are making processors available via cloud services. But Jim Clarke, who heads Intel’s quantum efforts, said these differences were due to the company’s distinct approach to developing quantum computers.
Typical superconducting quantum circuits, such as qubits—basic processing units of a quantum computer, must be operated at very low temperatures, of a few 10s of millikelvin, or hundredths of a degree from absolute zero temperature. These temperatures are today easily accessible in modern refrigerators. However, the intrinsic temperature of devices turns out to be much higher because the materials required to make good qubit circuits are by their nature very poor thermal conductors. This thermalization problem becomes more and more acute as the scale and complexity of circuits grow.
Much like water (or liquid nitrogen) cooling is sometimes used to effectively cool down high-performance digital computers, a quantum computer could benefit from similar liquid cooling. But at the very low temperatures that quantum circuits operate, most liquids will have turned into ice. Only two isotopes of Helium, Helium-3 and Helium-4, remain in the liquid form at millikelvin temperatures.
In recent work published in Nature Communications, researchers from the National Physical Laboratory, Royal Holloway University of London, Chalmers University of Technology and Google developed new technology to cool down a quantum circuit to less than a thousand of a degree above absolute zero, almost 100 times lower temperature than achieved before. This was made possible by immersing the circuit in liquid 3 He, chosen for its superior thermal properties.
