(Press-News.org)
A research paper by scientists at Westlake University presented a novel 3D cell culturing and noninvasive characterization technique of neural spheroids, holding a potential application in development of brain organoids.
The new research paper, published on Mar. 5 in the journal Cyborg and Bionic Systems, designed a wire-embedded 3D neural spheroid culture device that not only supports the culture and growth of neural spheroids but also facilitates real-time monitoring of both interior and exterior neural signals without damage.
“In recent years, the field of in vitro neural tissue modeling has undergone substantial advancements, providing researchers with powerful tools to investigate the complexities of neural circuitry. For instance, Osaki et al. explored an in vitro neural tissue model for interregional connections, connecting 2 cerebral organoids using a bundle of reciprocally extended axons. The interconnected organoids displayed a more intricate and robust oscillatory activity compared to conventional or directly fused cerebral organoids, indicating that axonal connections between organoids augment and sustain complex network behaviors. These groundbreaking studies herald the advent of novel pathways for elucidating the intricacies of the human brain.” explained study author Sumin Bian, a professor at Westlake University. Based on recent advances in neuroscience, the authors introduce an innovative in vitro neuroglobular model specifically designed to study interregional neural connections. The model incorporates a novel line embedded device that supports the cultivation and growth of neuroglobules in a controlled environment.
“In this study, a novel wire-inserted cell culture device for noninvasive recording signals from inside NCs of spheroids was proposed, enabling the systematic investigation of their structural and functional properties. While our culturing device for neural spheroids offers numerous advantages and insights, it is important to acknowledge its limitations.” said Sumin Bian. Totally, authors have presented a novel wire-inserted cell culture device that substantially elevates the capacity to noninvasively record signals from within neural spheroids. This approach not only permits a systematic examination of structural and functional properties of neural spheroids but also exhibits numerous advantages over existing methods. Our device fosters the successful cultivation and integration of axons within the spheroids, establishing robust interconnections between paired neural spheroids. This represents a pivotal advancement in modeling intricate neural networks and elucidating their dynamics.
Authors of the paper include Hongyong Zhang, Nan Huang, Sumin Bian, Mohamad Sawan.

A research team led by Dr. Ju-Yul Lee and Dr. Seil Kim from the Energy & Environment Materials Research Division at the Korea Institute of Materials Science (KIMS) has developed the world’s first eco-friendly silver (Ag) plating technology using a phosphorus (P) compound as a key plating component. This breakthrough technology enables silver plating without the use of highly toxic cyanide, by formulating an acidic plating solution based on phosphorus compounds that successfully produces uniform and stable silver thin films.
Silver plating is an essential process for enhancing electrical signal transmission in semiconductors, electronic components, and circuit boards. Conventional ...

Microbial research suggests that biodiversity does not always increase ecosystem stability. Although many conservationists believe biodiversity is intrinsically valuable, the protection of biodiversity has also been argued for on the basis that diversity makes ecosystems healthier and more stable. But are highly diverse ecosystems more stable and productive than ecosystems with low diversity? The question has been investigated in plants and animals, where some evidence suggests a link between biodiversity and various measures of ecosystem function, but few studies have investigated the hypothesis’ applicability among microbes, ...

Researchers have demonstrated a new quantum sensing technique that widely surpasses conventional methods, potentially accelerating advances in fields ranging from medical imaging to foundational physics research, as shown in a new study published today in Nature Communications.
For decades, the performance of quantum sensors has been limited by decoherence, which is unpredictable behavior caused by environmental noise. “Decoherence causes the state of a quantum system to become randomly scrambled, erasing any quantum sensing signal,” said Eli Levenson-Falk, senior author of the study, associate professor of physics and astronomy at the USC Dornsife College of Letters, ...

Long term field study confirms effectiveness of new technology
Oxford & Harpenden, UK. 29 April 2025. Enhancing wheat plants’ sugar signalling ability could deliver increased yields of up to 12%, according to researchers from Rothamsted, Oxford University and the Rosalind Franklin Institute in a study published today in the journal Nature Biotechnology. That is an order of magnitude greater than annual yield increases currently being achieved through breeding.
The effect was achieved by applying a Trehalose 6-phosphate (T6P) pre-signalling molecule to the plants. T6P is a signalling molecule that ...

Depression in young teens could be easier to treat than in adulthood due to the symptoms being more flexible and not yet ingrained, a study shows.
Researchers found that interactions between depressive symptoms – like sadness, fatigue and a lack of interest – are less predictable in teens but become more fixed in adults, which can lead to persistent depression.
The findings highlight the importance of targeting depression at an early age, when symptoms are still changing, experts say.
Depression is a complex condition, characterised by a range of connected symptoms. Current interventions treat overall depression severity and do not consider ...

Researchers from the Sant Pau Research Institute (IR Sant Pau), in collaboration with Sant Pau Hospital and the Josep Carreras Leukaemia Research Institute, have developed an innovative CAR-T cell therapy targeting the CD30 protein (HSP-CAR30), which has shown high efficacy in patients with refractory CD30+ lymphoma. A Phase I clinical trial, whose results have been published in the prestigious journal Blood, reveals that this new CAR-T30 therapy promotes the expansion of memory T cells, leading to long-lasting responses and improved clinical outcomes in treated patients.
Hodgkin lymphoma and other CD30+ lymphomas have posed ...

Much of the work devoted to exploring potential sex-specific differences in exercise or sports performance has been derived from laboratory-based studies. While these studies are typically well-controlled and guide our understanding of physiological mechanisms, they may lack pragmatic or practical relevance to the ‘real world’.
