Cultured neural tissues have been widely used as a simplified experimental model for brain research. However, existing devices for growing and recording neural tissues, which are manufactured using semiconductor processes, have limitations in terms of shape modification and the implementation of three-dimensional (3D) structures.

By "thinking outside the box," a KAIST research team has successfully created a customized 3D neural chip. They first used a 3D printer to fabricate a hollow channel structure, then used capillary action to automatically fill the channels with conductive ink, creating the electrodes and wiring. This achievement is expected to significantly increase the design freedom and versatility of brain science and brain engineering research platforms.

In 2024, 3.4 billion people lacked safely managed sanitation

Sustainable Development Goal 6 has a target to achieve access to adequate and equitable sanitation and hygiene for all by 2030

Portable toilet service of container-based sanitation is having a positive impact

An international study on container-based sanitation (CBS) systems has found that this portable toilet option significantly improves the quality of life for people living in urban slums in Kenya, Peru and South Africa.

CBS systems use sealed, portable toilet containers that are collected, emptied, and cleaned regularly as part of a subscription-based service. Unlike traditional sanitation solutions that require heavy infrastructure, CBS offers a flexible and practical alternative for densely populated urban areas.

In August, Pensoft had the honour of welcoming colleagues from the Vietnam Academy of Science and Technology (VAST) to the headquarters of the open-access scholarly publisher and technology provider in Sofia, Bulgaria. The visit was marked by engaging discussions on scholarly publishing, future innovations, current challenges in academia and potential collaborations. The highlight of the meeting was the formal signing of a Memorandum of Understanding (MoU) between Prof. Dr. Lyubomir Penev, Pensoft’s CEO and founder, and Prof. Dr. Thai Hoang, Vice Chairman of the Scientific Council of Materials Science at VAST and the Editor‑in‑Chief of the Vietnam Journal of Science and Technology.

It is anticipated that, within just a few decades, the surging volume of digital data will constitute one of the world’s largest energy consumers. Now, researchers at Chalmers University of Technology, Sweden, have made a breakthrough that could shift the paradigm: an atomically thin material that enables two opposing magnetic forces to coexist – dramatically reducing energy consumption in memory devices by a factor of ten. This discovery could pave the way for a new generation of ultra-efficient, reliable memory solutions for AI, mobile technology and advanced data processing.

This discovery paves the way for more cost-effective and efficient catalysts that could significantly lower the barriers to industrial-scale CO₂ conversion processes. The technology holds promise for contributing to the development of renewable energy sources, reducing reliance on fossil fuels, and mitigating the impacts of climate change. It may also inspire further research into other catalyst-support combinations, potentially leading to breakthroughs in various electrochemical applications.
