For the first time, scientists have invented a liquid ink that doctors can print onto a patient’s scalp to measure brain activity. The technology, presented December 2 in the journal Cell Biomaterials, offers a promising alternative to the cumbersome process currently used for monitoring brainwaves and diagnosing neurological conditions. It also has the potential to enhance non-invasive brain-computer interface applications.

“Our innovations in sensor design, biocompatible ink, and high-speed printing pave the way for future on-body manufacturing of electronic tattoo sensors, with broad applications both within and beyond ,” says Nanshu Lu, the paper’s co-corresponding author at the University of Texas at Austin.

Electroencephalography (EEG) is an important tool for diagnosing a variety of neurological conditions, including seizures, , epilepsy, and brain injuries. During a traditional EEG test, technicians measure the patient’s scalp with rulers and pencils, marking over a dozen spots where they will glue on electrodes, which are connected to a data-collection machine via long wires to monitor the patient’s brain activity. This setup is time consuming and cumbersome, and it can be uncomfortable for many patients, who must sit through the EEG test for hours.

In recent years, quantum physicists and engineers have been trying to develop quantum computer processors that perform better than classical computers on some tasks. Yet conclusive demonstrations proving that quantum systems perform better than their classical counterparts (i.e., realizations of a quantum advantage) remain scarce, due to various experimental challenges.

Researchers at Henan Key Laboratory of Quantum Information and Cryptography and the S. N. Bose National Center for Basic Sciences carried out an experiment aimed at establishing the of an elementary quantum system for .

Their paper, published in Physical Review Letters, demonstrates that a single qubit can outperform a classical bit in a communication task that does not involve any shared randomness (i.e., classically correlated random variables between communicating parties).

A new quantum algorithm developed by University of Georgia statisticians addresses one of the most complex challenges in single-cell analysis, signaling significant impact in both the fields of computational biology and quantum computing.

The study, “Bisection Grover’s Search Algorithm and Its Application in Analyzing CITE-seq Data,” was published in the Journal of the American Statistical Association on Sept. 20.

While traditional approaches struggle to handle the immense amount of data generated from measuring both RNA and in individual cells, the new enables analysis of data from a single-cell technology known as CITE-seq. It allows for selection of the most important markers from billions of possible combinations—a task that would be formidable using classical methods.

Leading by example is a core belief. I’ve always advocated for a leadership approach that empowers the team and fosters a culture of continuous learning. The focus on sustainability isn’t just about technology—it’s about cultivating an environment where innovation thrives and where every team member is aligned with the vision of creating a more energy-efficient future.

Operating on three core principles (empowerment, communication and accountability) drives success and ensures every decision made is in line with long-term goals of sustainability and growth. Empowering the team means trusting them to innovate and make decisions that move the company forward, while open communication ensures alignment as the organization scales.

Looking ahead, the future of data centers lies in sustainability and transparency. As the demand for computing power grows, so too will the need for solutions that minimize environmental impact.

The manipulation of mechanical strain in materials, also known as strain engineering, has allowed engineers to advance electronics over the past decades, for instance enhancing the mobility of charge carriers in devices. Over the past few years, some studies have tried to devise effective strategies to manipulate strain in two-dimensional (2D) semiconductors that are compatible with existing industrial processes.

Researchers at Stanford University recently introduced a CMOS-compatible approach to engineer the (i.e., stretchiness) in monolayer semiconductor transistors.

This approach, outlined in a paper published in Nature Electronics, relies on the use of silicon nitride capping layers that can impart strain on monolayer molybdenum disulfide (MoS2) transistors integrated on silicon substrates.

The classic strategy of continually shrinking transistors in silicon chips to create faster, more powerful computers is starting to fail us.

“Even though silicon works at these extremely small dimensions, the energy efficiency required to do one calculation has been going up, and this makes it highly unsustainable,” Deep Jariwala, an engineering professor at the University of Pennsylvania, told the Wall Street Journal in 2022. “Energy-wise it doesn’t make sense anymore.”

We need to solve this sustainability issue if we want to continue improving our tech without causing further damage to the environment, and the hunt for solutions has some researchers taking a closer look at chips made from semiconducting materials other than silicon, including gallium nitride, a compound made of gallium and nitrogen.

A team of engineers at the University of Science and Technology of China has developed a new way to code data onto a diamond with higher density than prior methods. In their paper published in the journal Nature Photonics, the group notes that such optical discs could hold data safely at room temperature for millions of years.

Prior research has shown that it is possible to code data onto a diamond, allowing for much longer data than any other known method. But such efforts have produced low-density storage. In this new effort, the research team developed a new method for etching data onto a diamond that allows for much denser data storage, and thus for storing more information onto a single diamond.

In their work, the researchers used diamond pieces just a few millimeters in length—they were pursuing a proof of concept, not a true storage medium. Future versions, they note, could be the size of a Blu-ray disc. The new method involved the use of a to remove single carbon atoms from the surface of the diamond, leaving a tiny cavity. The cavity, the researchers note, exhibits a certain level of brightness when another laser is shone on it.
