Computer simulations reveal how cells break down the endoplasmic reticulum

Posted by in category: computing

Inside cells, there exists an extensive system of canals known as the endoplasmic reticulum (ER), which consists of membrane-encased tubes that are partially broken down as needed—for instance in case of a nutrient deficiency. As part of this process, bulges or protrusions form in the membrane, which then pinch off and are recycled by the cell.

New ‘gold-plated’ superconductor could be the foundation for massively scaled-up quantum computers in the future

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

The interface superconductor underwent a transition under a magnetic field and became more robust, the scientists said in the paper This suggests it has transformed into a “triplet superconductor.” — a type of superconductor that is more resistant to magnetic fields than conventional superconductors.

They conducted the research in conjunction with the National Institute of Standards and Technology. In earlier work, they demonstrated that thin films of gold and niobium naturally suppress decoherence — the loss of quantum properties due to external environmental interference.

Given its robust quantum qualities and its ability to suppress decoherence, this new superconducting material promises to be ideal for use in quantum computers, the scientists said. Minimizing decoherence within the system is a key challenge, which necessitates extreme measures to isolate the quantum computer from external influences, such as shifts in temperature or electromagnetic interference, as well as the use of error-correcting algorithms to ensure calculations remain accurate.

Creating compact near-sensor computing chips via 3D integration of 2D materials

Posted by in categories: computing, materials

Polyethylene (PE) is one of the most widely used and versatile plastic materials globally, prized for its cost-effectiveness, lightweight properties and ease of formability. These characteristics make PE indispensable across a broad spectrum of applications, from packaging materials to structural plastics.

Could Data Be Stored in Plastic? Here’s How It Works

Posted by in categories: biotech/medical, computing

A new technique enables data storage in synthetic polymers, allowing direct bit access without full sequence decoding, significantly increasing storage density and stability, demonstrated by encoding a university address in ASCII within a polymer.

The need for data storage is growing, with many types of data requiring long-term preservation. Synthetic polymers present an efficient alternative to traditional storage media, as they can store information using less space and energy. However, conventional retrieval methods, like mass spectrometry, limit the length—and therefore the storage capacity—of individual polymer chains. Now, as reported in Angewandte Chemie, researchers have developed a new approach that overcomes this limitation, enabling direct access to specific data bits without having to read the entire chain.

Shocking New Memory Tech: Crystal-to-Glass Transformation Using a Billion Times Less Energy

Posted by in categories: computing, materials

A breakthrough discovery in indium selenide could revolutionize memory storage technology by enabling crystalline-to-glass transitions with minimal energy.

Researchers found that this transformation can occur through mechanical shocks induced by continuous electric current, bypassing the energy-intensive melting and quenching process. This new approach reduces energy consumption by a billion times, potentially enabling more efficient data storage devices.

Discover the Quantum Power Hidden Inside Diamonds

Posted by in categories: computing, quantum physics

The SPINNING project, under the leadership of the Fraunhofer Institute, is pioneering a quantum computer using diamond-based spin photons, promising lower cooling requirements, longer operating times, and lower error rates compared to conventional quantum systems.

This innovative approach leverages the unique properties of diamonds to create stable qubits, aiming for high scalability and fidelity in quantum computing. Recent achievements include the successful demonstration of qubit entanglement over long distances, significantly outperforming traditional quantum computers in error rate and coherence time.

Flexible circuits made with silk and graphene

Posted by in categories: computing, materials

After thousands of years as a highly valuable commodity, silk continues to surprise. Now it may help usher in a whole new direction for microelectronics and computing.

While silk protein has been deployed in designer electronics, its use is currently limited in part because silk fibers are a messy tangle of spaghetti-like strands.

Now, a research team led by scientists at the Department of Energy’s Pacific Northwest National Laboratory has tamed the tangle. They report in the journal Science Advances (“Two-dimensional silk”) that they have achieved a uniform two-dimensional (2D) layer of silk protein fragments, or “fibroins,” on graphene, a carbon-based material useful for its excellent electrical conductivity.

Real-Life Star Wars Tech: MIT Researchers Have Created a Miniature “Tractor Beam” To Capture Cells

Posted by in categories: biotech/medical, computing, tractor beam

MIT researchers have developed a miniature, chip-based “tractor beam,” like the one that captures the Millennium Falcon in the film “Star Wars,” that could someday help biologists and clinicians study DNA, classify cells, and investigate the mechanisms of disease.

Small enough to fit in the palm of your hand, the device uses a beam of light emitted by a silicon-photonics chip to manipulate particles millimeters away from the chip surface. The light can penetrate the glass cover slips that protect samples used in biological experiments, enabling cells to remain in a sterile environment.

Traditional optical tweezers, which trap and manipulate particles using light, usually require bulky microscope setups, but chip-based optical tweezers could offer a more compact, mass-manufacturable, broadly accessible, and high-throughput solution for optical manipulation in biological experiments.

Move Over Plastics: Revolutionary Soft, Sustainable Material Set To Transform Medical Devices and Wearable Tech

Posted by in categories: biotech/medical, computing, nanotechnology, wearables

Step aside, hard and rigid materials — a new soft, sustainable electroactive material is here, ready to unlock new possibilities for medical devices, wearable technology, and human-computer interfaces.

Using peptides and a snippet of the large molecules in plastics, Northwestern University materials scientists have developed materials made of tiny, flexible nano-sized ribbons that can be charged just like a battery to store energy or record digital information. Highly energy efficient, biocompatible, and made from sustainable materials, the systems could give rise to new types of ultralight electronic devices while reducing the environmental impact of electronic manufacturing and disposal.

The study was recently published in the journal Nature.
