New organoid culture method can verify human toxicity of nanomaterials

Posted by in categories: biotech/medical, nanotechnology

The organoids were treated with zinc oxide nanoparticles (ZnO NPs), which are a liver toxic material, and nontoxic gold nanoparticles (AuNPs). The comparison showed that the toxicity of each material could be accurately observed, in contrast to the conventional method.

Ahruem Baek, a senior researcher at KRISS, said, “Based on our results, we will establish standard nanomaterial and nanomedicine safety assessment procedures using organoids, contributing to the advancement of Korea’s nano-industry.”

The results from this study may allow for rapid and accurate safety assessment of nanomaterials and nanomedicine using organoids, contributing to the safe utilization of nanomaterials in various strategic technical fields.

AI-based approach matches protein interaction partners

Posted by in categories: biotech/medical, robotics/AI

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

Posted by in categories: biotech/medical, internet, security

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

Posted by in category: biotech/medical

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

Posted by in categories: biotech/medical, neuroscience

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…

New research points to possibility for testing to explore early-stage Alzheimer’s disease

Posted by in categories: biotech/medical, neuroscience

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

Posted by in categories: bioengineering, biotech/medical, food

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

Posted by in categories: biotech/medical, life extension, neuroscience

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.
