The advance brings quantum error correction a step closer to reality.

In the future, quantum computers may be able to solve problems that are far too complex for today’s most powerful supercomputers. To realize this promise, quantum versions of error correction codes must be able to account for computational errors faster than they occur.

However, today’s quantum computers are not yet robust enough to realize such error correction at commercially relevant scales.

Researchers at ETH Zurich recently identified a previously unknown compartment in mammalian cells. They have named it the exclusome. It is made up of DNA rings known as plasmids. The researchers have published details of their discovery in the journal Molecular Biology of the Cell.

The new compartment is in the cell plasma; it is previously uncharacterized in the literature. It is exceptional because eukaryotic cells (cells with nuclei) usually keep most of their DNA in the cell nucleus, where it is organized into chromosomes.

Some of the plasmids that end up in the exclusome originate from outside the cell, while others—known as telomeric rings—come from the capped ends of chromosomes, the telomeres. Particularly in certain cancer cells, the ones from the telomeres are regularly pinched off and joined together to form rings. However, these don’t contain the blueprints for proteins.

A team led by Professor Choi Hong-Soo in the Department of Robotics and Mechatronics Engineering at DGIST has discovered a method to enhance the penetration of magnetic nanoparticles into cancer cells and their magnetic hyperthermia effects through research on chain disassembly and magnetic propulsion mechanisms using a rotational magnetic field.

Published in the journal ACS Nano, their study focused on the delivery of magnetic therapeutic agents using magnetic fields, an area receiving attention in the field of cancer treatment. It is expected to contribute significantly by improving drug delivery efficiency and therapeutic effects in targeted cancer treatments.

Recently, the development of targeted therapeutics that selectively treat cancer cells has been gaining attention in the field of cancer treatment. Among them, research on magnetic carriers that target cancer cells using magnetic fields is underway. However, a problem arises when magnetic nanoparticles are exposed to a uniform magnetic field with a general form; they form long chains in the direction of the magnetic field, making penetration into cancer cells or tumors difficult and reducing the therapeutic efficacy.

Starlink is upgrading its satellite constellation to rev up its internet service. The company launched 8,000 upgraded space lasers capable of transmitting data at speeds up to 100 Gbps.

On September 26, Starlink posted a look at the improved V2 Mini satellites, which will enhance the constellation’s speed, reliability, and reach.

“Our next generation Starlink optical space lasers (pew pew!) were launched to orbit on Monday,” Starlink tweeted on X (formerly Twitter).

Renewable energy grids need lots of energy storage – and EVs plugged into charging stations represent a huge, city-wide battery just waiting to help out. The Dutch city of Utrecht is about to pioneer a clever way to kickstart two-way charging.

The idea has been done plenty at the domestic level – where devices like Toyota’s V2H (vehicle-to-home) charging system can turn an electric car into a high-powered backup power supply capable of running your whole home for days at a time.

And people have been talking about it on a broader, city-wide scale since the dawn of the EV revolution; the same high power density batteries that makes EVs so quick to accelerate make them perfect for quickly sending power back into the grid to smooth out demand spikes.

Scholars at Carnegie Mellon University recently offered what they call a “High-Modality Multimodal Transformer,” which combines not just text, image, video, and speech but also database table information and time series data. Lead author Paul Pu Liang and colleagues report that they observed “a crucial scaling behavior” of the 10-mode neural network. “Performance continues to improve with each modality added, and it transfers to entirely new modalities and tasks.”

Scholars Yiyuan Zhang and colleagues at the Multimedia Lab of The Chinese University of Hong Kong boosted the number of modalities to a dozen in their Meta-Transformer. Its point clouds model 3D vision, while its hyper-spectral sensing data represents electromagnetic energy reflected back from the ground to fly-over images of landscapes.

The immediate payoff of multi-modality will simply be to enrich the output of a thing such as ChatGPT in ways that go far beyond the “demo” mode. A children’s storybook, a book with text passages combined with pictures illustrating the text, is one immediate example. By combining the language and image attributes, the kinds of pictures created by the diffusion process can be more subtly controlled from picture to picture.
