Soft bioelectronic devices are made from polymer-based and hybrid electronic materials that form natural interfaces with the human body. In this Review, the authors present recent developments in soft bioelectronic sensors and actuators, and discuss system-level integration for wearable and implantable medical applications.

Organic electrochemical neurons and synapses with ion mediated spiking
The integration of artificial neuromorphic devices with biological systems plays a fundamental role for future brain-machine interfaces, prosthetics, and intelligent soft robotics. Harikesh et al. demonstrate all-printed organic electrochemical neurons on Venus flytrap that is controlled to open and close.
AI-based approach matches protein interaction partners
Proteins are the building blocks of life, involved in virtually every biological process. Understanding how proteins interact with each other is crucial for deciphering the complexities of cellular functions, and has significant implications for drug development and the treatment of diseases.
New security loophole allows spying on internet users visiting websites and watching videos
Many people are familiar with oncogenes—genes long known to be involved in cancers in humans, such as the gene Src. What’s less widely understood is that oncogenes didn’t evolve just to cause cancer in species, but rather to control events of normal growth and differentiation.
Resource: List of Biotechnology Companies to Watch
To help myself and others keep track of the fast-paced world of biotech, I have put together this list of 107 companies and notable research nonprofits! I wrote down some important facts about each entry as well as included links to their websites.
PDF version: List of Biotechnology Companies to Watch – by Logan Thrasher Collins
I created this list of organizations (107 total to date) to serve as a resource to help people learn about and keep track of key biotechnology companies. Some of these are emerging startups, some are established giants, and some provide useful services. Some notable nonprofit organizations are included as well. Though this list is far from comprehensive, I have tried to cover as many of the key players as possible. It is also important to realize that this landscape is constantly changing, so some of the information on this list will eventually transition into antiquity. The list was originally started over the course of 2021, updated during the summer of 2022, and updated again during the summer of 2024. I hope you enjoy delving into the exciting world of biotechnology!
UK boy has brain implant fitted to control epilepsy seizures in world first
A UK teenager with severe epilepsy has become the first person in the world to be fitted with a brain implant aimed at bringing seizures under control.
Oran Knowlson’s neurostimulator sits under the skull and sends electrical signals deep into the brain, reducing his daytime seizures by 80%.
His…
His mother, Justine, said that her son had been happier, chattier and had a much better quality of life since receiving the device. “The future looks hopeful, which I wouldn’t have dreamed of saying six months ago,” she said.
Martin Tisdall, a consultant paediatric neurosurgeon who led the surgical team at Great Ormond Street hospital (Gosh) in London, said: “For Oran and his family, epilepsy completely changed their lives and so to see him riding a horse and getting his independence back is absolutely astounding. We couldn’t be happier to be part of their journey.”
Oran, who is 13 and lives in Somerset, had the surgery in October as part of a trial at Gosh in partnership with University College London, King’s College hospital and the University of Oxford. Oran has Lennox-Gastaut syndrome, external, a treatment-resistant form of epilepsy which he developed at the age of three.
New research points to possibility for testing to explore early-stage Alzheimer’s disease
Research in nonhuman primates is opening the possibility of testing treatments for the early stages of Alzheimer’s and similar diseases, before extensive brain cell death and dementia set in. A study published in Alzheimer’s & Dementia shows up to a six-month window in which disease progress could be tracked and treatments tested in rhesus macaques.
99% gene transmission: China’s CRISPR tool boosts food security
Chinese scientists have engineered a solution by which they could bypass natural plant gene inheritance. They aim to deploy a CRISPR-based gene editing system to help the transmission of preferred genes even when they aren’t suitable for a plant.
The scientists devised a system that would use both a toxin and an antidote which would directly affect the male plant germline. Through this process, the researchers could overcome the natural Mendelian transmission rate. This can help increase the gene transmission rates up to 99% over two generations.
TERT activation targets DNA methylation and multiple aging hallmarks
This study identifies a small molecule (TAC) that restores physiological levels of TERT throughout aged tissues, resulting in the rejuvenation of multiple tissues. Specifically, TAC administration in very aged mice alleviates multiple aging hallmarks such as cellular senescence and systemic inflammation, promotes new neuron formation with improved cognitive ability, enhances neuromuscular function, and is well tolerated with no evidence of toxicity.
