Earlier today, Samsung announced its own solution for satellite communication on smartphones. The company unveiled the 5G non-terrestrial networks (NTN) modem so phones can communicate with satellites in locations where there is no cellular network connectivity.

The company said that it aims to integrate this tech into its own Exynos chip, which is used in a lot of Samsung smartphones — but not the current flagship device, the Samsung Galaxy S23. The Korean tech giant describes this tech as using “satellites and other non-terrestrial vehicles” to provide connectivity in remote areas.

The move follows Apple, which launched satellite connectivity with iPhone 14 and 14 Pro for off-grid connectivity. The company first made this tech available in the U.S. and Canada, later expanding it to France, Germany, Ireland and the U.K. Apple relies on Globalstar’s satellite network.

Today’s news from the frontier of quantum computing includes Amazon Web Services’ release of cloud-based simulation software for modeling the electromagnetic properties of quantum hardware, Google’s latest technological advance aimed at lowering the error rate of quantum calculations, and new recommendations about the public sector’s role on the frontier.

Apple has reportedly secured all available orders for N3, TSMC’s first-generation 3-nanometer process that is likely to be used in the upcoming iPhone 15 Pro lineup as well as new MacBooks scheduled for launch in the second half of 2023.

According to a paywalled DigiTimes report, Apple has procured 100% of the initial N3 supply, which is said to have a high yield, despite the higher costs involved and the decline in the foundry’s utilization rate in the first half of 2023. Mass production of TSMC’s 3nm process began in late December, and the foundry has scaled up process capacity at a gradual pace with monthly output set to reach 45,000 wafers in March, according to the report’s sources.

For the first time, an international team of researchers, including those from the University of Tokyo’s Institute for Solid State Physics, has demonstrated a switch, analogous to a transistor, made from a single molecule called fullerene.

By using a carefully tuned laser pulse, the researchers are able to use fullerene to switch the path of an incoming electron in a predictable way. This switching process can be three to six orders of magnitude faster than switches in microchips, depending on the laser pulses used. Fullerene switches in a network could produce a computer beyond what is possible with electronic transistors, and they could also lead to unprecedented levels of resolution in microscopic imaging devices.

More than 70 years ago, physicists discovered that molecules emit electrons in the presence of electric fields, and later on, in certain wavelengths of light. The electron emissions created patterns that enticed curiosity but eluded explanation. This has changed thanks to a new theoretical analysis, the ramification of which could not only lead to new high-tech applications, but also improve our ability to scrutinize the physical world itself.

Biodegradable, wood-based computer chips can perform just as well as chips commonly used for wireless communication, according to new research.

The inventors argue that the new chips could help address the global problem of rapidly accumulating electronic waste, some of which contains potentially toxic materials. The results also show that a transparent, wood-derived material called nanocellulose paper is an attractive alternative to plastic as a surface for flexible electronics.

In modern electronics, a large amount of heat is produced as waste during usage—this is why devices such as laptops and mobile phones become warm during use, and require cooling solutions. In the last decade, the concept of managing this heat using electricity has been tested, leading to the development of electrochemical thermal transistors—devices that can be used to control heat flow with electrical signals.

Currently, liquid-state thermal transistors are in use, but have critical limitations: chiefly, any leakage causes the device to stop working.

A research team at Hokkaido University lead by Professor Hiromichi Ohta at the Research Institute for Electronic science has developed the first solid-state electrochemical thermal transistor. Their invention, described in the journal Advanced Functional Materials, is much more stable than and just as effective as current liquid-state thermal transistors.

A multidisciplinary Northwestern University research team has created a groundbreaking transistor that is expected to be optimal for bioelectronics that are high-performance, lightweight, and flexible.

The new electrochemical transistor is compatible with both blood and water and has the ability to amplify significant signals, making it highly beneficial for biomedical sensing. This transistor could make it possible to develop wearable devices that can perform on-site signal processing right at the biology-device interface. Some potential applications include monitoring heart rate and levels of sodium and potassium in the blood, as well as tracking eye movements to study sleep disorders.

“All modern electronics use transistors, which rapidly turn current on and off,” said Tobin J. Marks, a co-corresponding author of the study. “Here we use chemistry to enhance the switching. Our electrochemical transistor takes performance to a totally new level. You have all the properties of a conventional transistor but far higher transconductance (a measure of the amplification it can deliver), ultra-stable cycling of the switching properties, a small footprint that can enable high-density integration, and easy, low-cost fabrication.”

Do we see the world as it really is, or are we creating our own reality? We delve into the neuroscience behind the world that we experience.

Such credentials in the wrong hands could be dangerous, experts say, potentially allowing physical access to data centers. The affected data center operators say the stolen information didn’t pose risks for customer IT systems.
