New material design for transistors could downsize next-gen tech

Posted by in categories: computing, materials

By better taming the Jekyll-and-Hyde nature of an alternative to the semiconductor—one that transitions from electricity-resisting insulator to current-conducting metal—Nebraska’s Xia Hong and colleagues may have unlocked a new path to smaller, more efficient digital devices. The team reports its findings in the journal Nature Communications.

The semiconductor’s ability to conduct electricity in the Goldilocks zone—poorer than a metal, better than an insulator—positioned it as the just-right choice for engineers looking to build transistors, the tiny on-off switches that encode the 1s and 0s of binary. Apply some voltage to the control knob known as a gate insulator, and the semiconductor channel allows electric current to flow ; remove it, and that flow ceases.

Millions of those nanoscopic, semiconductor-based transistors now coat modern microchips, switching on and off to collectively process or store data. But as minuscule as the transistors already are, the demands of consumers and competition continue pushing to shrink them even further, either for the sake of squeezing in more functionality or downsizing the devices that house them.

Nvidia reportedly selects Intel Foundry Services for GPU packaging production — could produce over 300,000 H100 GPUs per month

Posted by in category: computing

This is the first good news I’ve heard from Intel in about 5 years. All they are doing here is gluing memory chips made by others to GPUs made by others, but it is something!


Nvidia will start using Intel’s Foveros packaging technology for some of its high-performance datacenter grade GPUs in Q2, according to a report.

Tracing the evolution of sign languages using computer modeling

Posted by in category: computing

An international team of linguistics experts has traced the origins of the most common modern sign languages using a computer model to compare them against one another. The research is published in the journal Science.

In this new effort, the research team noted that while studies have traced the linguistic history of written languages, little work has been done on the of sign languages. They state that there are more than 300 sign languages used by hearing-impaired people around the globe, and little is known about their origins or how they might have impacted one another.

Sign languages, like spoken and written languages, are unique to groups or cultures, with many corresponding to their written counterparts—there is a Spanish sign language, for example, and French, Spanish and Japanese.

A physical qubit with built-in error correction

Posted by in categories: computing, information science, quantum physics

There has been significant progress in the field of quantum computing. Big global players, such as Google and IBM, are already offering cloud-based quantum computing services. However, quantum computers cannot yet help with problems that occur when standard computers reach the limits of their capacities because the availability of qubits or quantum bits, i.e., the basic units of quantum information, is still insufficient.

One of the reasons for this is that bare qubits are not of immediate use for running a quantum algorithm. While the binary bits of customary computers store information in the form of fixed values of either 0 or 1, qubits can represent 0 and 1 at one and the same time, bringing probability as to their value into play. This is known as quantum superposition.

This makes them very susceptible to external influences, which means that the information they store can readily be lost. In order to ensure that quantum computers supply reliable results, it is necessary to generate a genuine entanglement to join together several physical qubits to form a logical . Should one of these physical qubits fail, the other qubits will retain the information. However, one of the main difficulties preventing the development of functional quantum computers is the large number of physical qubits required.

Sub-Wavelength Light Confinement Demonstrated in New III-V Semiconductor Nanocavity

Posted by in categories: computing, nanotechnology, quantum physics

New nanocavities pave the way for enhanced nanoscale lasers and LEDs that could enable faster data transmission using smaller, more energy-efficient devices.

As we transition to a new era in computing, there is a need for new devices that integrate electronic and photonic functionalities at the nanoscale while enhancing the interaction between photons and electrons. In an important step toward fulfilling this need, researchers have developed a new III-V semiconductor nanocavity that confines light at levels below the so-called diffraction limit.

“Nanocavities with ultrasmall mode volumes hold great promise for improving a wide range of photonic devices and technologies, from lasers and LEDs to quantum communication and sensing, while also opening up possibilities in emerging fields such as quantum computing,” said the leading author Meng Xiong from the Technical University of Denmark. “For example, light sources based on these nanocavities could significantly improve communication by enabling faster data transmission and strongly reduced energy consumption.

‘Heart-on-a-chip’ to test chemotherapies and other cancer drugs for heart toxicity

Posted by in categories: biotech/medical, computing

Chemotherapy can be toxic to heart cells. To help protect the hearts of cancer patients, Cedars-Sinai investigators have created a three-dimensional “heart-on-a-chip” to evaluate drug safety. In a study published in the journal Lab on a Chip, they show that the heart-on-a-chip, created using stem cells, accurately predicts the effects of drugs on human heart cells.

The investigators worked with induced pluripotent stem cells, which are that have been reprogrammed into stem cells and can be turned into any cell type in the body. They used the stem cells to create two types of heart cells, but instead of placing them all together in an unstructured cell culture dish, as is usually done in heart toxicity testing, the investigators introduced the cells into specialized chips.

The 3D chips feature two channels that are arranged to cross each other, keeping each cell type separate but allowing them to interact. The chips also allow for movement and the introduction of fluids.
