(Press-News.org) Bioengineered organs are no longer just structural substitutes. A new review published in Trends in Biotechnology introduces a groundbreaking concept: biohybrid-engineered tissue (BHET) platforms—living constructs integrated with electronics that can monitor, modulate, and even autonomously control their own functions.
The review, authored by Dr. Uijung Yong (Future IT Innovation Laboratory, Pohang University of Science and Technology (POSTECH)), Jihwan Kim (Department of Mechanical Engineering, POSTECH), and Prof. Jinah Jang (Department of Mechanical Engineering, Convergence IT Engineering, and School of Interdisciplinary Bioscience and Bioengineering, POSTECH), outlines how recent advances in biofabrication and biomedical electronics have pushed tissue engineering into new frontiers. Traditional bioengineered organs have been limited in their ability to replicate the complex and dynamic nature of human organs. BHET platforms aim to change that by turning passive constructs into intelligent systems.
The authors classify BHET platforms into three main types:
Tissue-sensor platforms capture real-time physiological data, such as electrical activity or metabolite levels, offering continuous insights into tissue health and function.
Tissue-electromodulator platforms actively control tissue behavior using targeted electrical stimulation, accelerating tissue maturation or modulating hormone release.
Tissue-communicator platforms integrate both sensing and stimulation to enable closed-loop feedback, allowing tissues to adapt autonomously to environmental cues, much like living organs do.
These systems have already shown promise in diverse applications: brain organoids learning through neural feedback, cardiac tissues synchronizing contractions with external pacing, and engineered β cells releasing insulin in response to electrical signals. Such platforms blur the line between biology and machine, turning tissues into responsive and programmable devices.
The review also explores future directions, including AI-driven control systems, conductive hydrogel electrodes, and scalable 3D bioprinting techniques that can bring intelligent tissue platforms closer to clinical applications.
“By incorporating bioelectronics into tissue engineering, we can create more functional and intelligent bioengineered organs,” said Prof. Jinah Jang. “Combining this with AI-based analytics will allow bioengineered organs to autonomously monitor and regulate their functions with unprecedented precision.”

Cassava witches’ broom disease takes flight in South America
2025-07-18
Alliance researchers and partners, including Embrapa, Brazil’s largest agricultural research organization, launched a rapid response plan to slow the spread and mitigate potentially devastating consequences for food security and livelihoods.
In 2023, cassava farmers in remote French Guiana watched in shock as their crops withered. They pulled dilapidated stems from the ground. Instead of unearthing massive root bunches, which are cornerstones of diets across South America, they found nothing larger ...
Recycled tyre tech boosts railway resilience and cuts waste
2025-07-18
New research has shown that a world-first system of rubber shock absorbers made from recycled tyres can significantly protect railway tracks from damage, addressing the dual challenges of high maintenance costs and national tyre waste.
The technology was validated over a two-year period by a collaborative team from the University of Technology Sydney (UTS), Sydney Trains, Transport for NSW, and industry partners EcoFlex and Bridgestone, following extensive monitoring at a live Sydney Trains freight line in Chullora.

From kelp to whales: marine heatwaves are reshaping ocean life
2025-07-17
New research from the University of Victoria (UVic) highlights how marine heatwaves can dramatically impact marine ecosystems and offers a stark preview of how future ocean warming will reshape ocean life.
From 2014 to 2016, the Pacific coast of North America experienced the longest marine heatwave ever recorded, with temperatures reaching two to six degrees above historical averages over a prolonged period. Researchers from UVic’s Baum Lab have compiled a comprehensive overview of the heatwave’s ecological impacts, reviewing the findings from 331 primary studies and governmental reports.
“The marine heatwave resulted in unprecedented ecological disturbance across thousands ...
Short-term digital mental health interventions reduces depression and anxiety in Ukrainian children and adolescents displaced by war

Short-term digital mental health interventions reduces depression and anxiety in Ukrainian children and adolescents displaced by war
In a first of its kind randomised controlled trial, researchers found delivering a problem solving digital mental health intervention to young Ukrainian refugees significantly reduced symptoms of depression and anxiety. The findings show that a small, low-cost, scalable intervention delivered in schools through mobile devices may support the ...
Guselkumab demonstrates superior efficacy in landmark clinical trials and offers new hope to Crohn’s disease patients
2025-07-17
New York, NY — July 17, 2025 — In a major advance for patients with Crohn’s disease, a new study led by researchers at Mount Sinai Health System found that guselkumab, a medication with a mechanism of action that is new to inflammatory bowel disease (IBD) treatment, outperformed an established standard of care in promoting intestinal healing and symptom relief.
These findings from two pivotal phase 3 trials known as GALAXI 2 and 3, published today in The Lancet, provided the basis for the recent Food and Drug Administration approval of guselkumab (brand name Tremfya) for the treatment of moderately to severely active Crohn’s ...
Here’s how the U.S. military can trim its massive carbon footprint
2025-07-17
As an institution, the U.S. military is the world’s single largest consumer of energy and emitter of climate-altering carbon pollution, on par with the entire nation of Venezuela.
Now for the first time, research by a University of Utah sociologist documented how military spending tracks in near lockstep with emissions. Brett Clark and his coauthors conclude that reducing those expenditures can lead to significant reductions of energy use and, thereby, carbon emissions.
Can the military play a role in climate ...
What is chronic venous insufficiency?
2025-07-17
DALLAS, July 17, 2025 — In light of reports from the White House that President Donald J. Trump has been diagnosed with Chronic Venous Insufficiency (CVI), the American Heart Association is sharing important information on the condition and its association with cardiovascular risk factors, disease and increased risk of death.
According to the Association, the world’s leading nonprofit organization focused on heart and brain health for all, chronic venous insufficiency (a form of chronic venous disease) is highly prevalent - especially in older adults. ...
Gene editing offers transformative solution to saving endangered species
2025-07-17
Gene editing technologies - such as those used in agriculture and de-extinction projects - can be repurposed to offer what an international team of scientists is calling a transformative solution for restoring genetic diversity and saving endangered species.
In a new Nature Reviews Biodiversity Perspective article published today, the authors explore the promises, challenges and ethical considerations of genome engineering, and propose an approach for its implementation into biodiversity conservation.
They argue that gene editing could recover lost genetic diversity in species at risk of extinction using historical samples, such as DNA from museum collections, biobanks ...

Cracking the code of force-driven chemistry
2025-07-17
When asked to think of a chemical reaction, you might picture bubbling liquids in a beaker, or maybe applying heat to a mixture until something transforms. But some of the most important reactions in nature and industry don’t need heat or solvents. Instead, they need force.
Mechanochemistry is where physical pressure or stress triggers chemical reactions. Imagine molecules being rammed together like bumper cars, or shaken up in a giant cocktail shaker. That shaking and colliding happens every day inside ...
