The Ethics and Security Challenge of Gene Editing

Posted by in categories: bioengineering, biotech/medical, ethics, genetics, military, neuroscience

The weaponization of the scientific and technological breakthroughs stemming from human genome research presents a serious global security challenge. Gene-editing pioneer and Nobel Laureate Jennifer Doudna often tells a story of a nightmare she once had. A colleague asked her to teach someone how her technology works. She went to meet the student and “was shocked to see Adolf Hitler, in the flesh.”

Doudna is not alone in being haunted by the power of science. Famously, having just returned home from Los Alamos in early 1945, John von Neumann awakened in panic. “What we are creating now is a monster whose influence is going to change history, provided there is any history left,” he stammered while straining to speak to his wife. He surmised, however, that “it would be impossible not to see it through, not only for military reasons, but it would also be unethical from the point of view of the scientists not to do what they knew is feasible, no matter what terrible consequences it may have.”

According to biographer Ananyo Bhattacharya, von Neumann saw what was happening in Nazi Germany and the USSR and believed that “the best he could do is allow politicians to make those [ethical and security] decisions: to put his brain in their hands.” Living through a devastating world war, the Manhattan Project polymath “had no trust left in human nature.”

Research to merge human brain cells with AI secures national defence funding

Posted by in categories: bioengineering, biological, neuroscience, robotics/AI, security

“The new research program, led by Associate Professor Adeel Razi, from the Turner Institute for Brain and Mental Health, in collaboration with Melbourne start-up Cortical Labs, involves growing around 800,000 brain cells living in a dish, which are then “taught” to perform goal-directed tasks. Last year the brain cells’ ability to perform a simple tennis-like computer game, Pong, received global attention for the team’s research.”


Monash University-led research into growing human brain cells onto silicon chips, with new continual learning capabilities to transform machine learning, has been awarded almost $600,000 AUD in the prestigious National Intelligence and Security Discovery Research Grants Program.

According to Associate Professor Razi, the research program’s work using lab-grown brain cells embedded onto silicon chips, “merges the fields of artificial intelligence and synthetic biology to create programmable biological computing platforms,” he said.

Robot made of LEGOs produces DNA machines

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

A team of ingenious bioengineers at Arizona State University (ASU) has harnessed the power of childhood nostalgia, unveiling a creative solution to a long-standing challenge in DNA origami research.

They’ve successfully employed a LEGO robotics kit to build an affordable, highly effective gradient mixer for purifying self-assembling DNA origami nanostructures. This innovative breakthrough, detailed in a paper published one PLOS ONE, promises to revolutionize how scientists approach DNA origami synthesis.

The creation of DNA origami structures is an intricate process, requiring precise purification of nanostructures. Traditionally, this purification step involved rate-zone centrifugation, relying on a costly piece of equipment called a gradient mixer. However, the maverick minds at ASU have demonstrated that even the iconic plastic bricks of LEGO can be repurposed for scientific advancement.

A synthetic biology platform enabling control over aging-associated stress response

Posted by in categories: bioengineering, biotech/medical, genetics, life extension, robotics/AI, virtual reality

Integrated Biosciences, a biotechnology company combining synthetic biology and machine learning to target aging, in collaboration with researchers at the University of California Santa Barbara, today announced a drug discovery platform that enables precise control of the integrated stress response (ISR), a biological pathway that is activated by cells in response to a wide variety of pathological and aging-associated conditions.

A new publication, “Optogenetic control of the integrated stress response reveals proportional encoding and the stress memory landscape,” authored by company founders and featured on the cover of Cell Systems describes a technique that triggers the ISR virtually using light and demonstrates how the accumulation of stress over time shifts a cell’s reaction from adaptation to apoptosis (programmed cell death).

“In a very real way, our platform puts cells into a virtual reality, making them experience stress in the absence of physical stressors,” said Maxwell Wilson, Ph.D., a co-founder of Integrated Biosciences and Assistant Professor of Molecular, Cellular, and Developmental Biology at the University of California Santa Barbara.

Scientists get a new view of digestion

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

Our gut microorganisms, collectively known as the gut microbiota, affect far more than digestion. Bacteria in our intestinal tracts influence brain activity — and even the likelihood of developing mental disorders. Decades of research have shown that a bacterially imbalanced gut can disrupt many systems in the human body, contributing to obesity, malnutrition and even cancer. In a study published May 10 in Nature, Stanford Medicine researchers and collaborators used an ingestible device to capture the diversity of microorganisms, viruses, proteins and bile in the small intestine.

The proof-of-concept results provide early evidence that there are more comprehensive ways to measure microbiota in the digestive system than current sampling methods — which mostly focus on stool — and shed new light on how resident gut microbes might contribute to human physiology and disease.

“This paper demonstrates a big leap forward in microbial detection and captures the living gut microbiota in a nutshell,” said co-senior author KC Huang, PhD, a professor of bioengineering and of microbiology and immunology, co-senior author with David Relman, MD, a professor of medicine and of microbiology and immunology. “Samples from current tools don’t fully represent what’s going on inside of us. But it’s all we’ve had — until now.”

Genetic engineering giants: is China poised to lead the way?

Posted by in categories: bioengineering, biotech/medical, genetics, law enforcement

For many people, when they hear China and genetic engineering in the same sentence, it is often synonymous with scandal, and gene-edited babies may spring to mind.

And, although it is true that nearly five years ago, researcher He Jiankui infamously claimed he had created the first ever gene-edited babies, before going to prison for three years, China has continued to pour a lot of money into genetic engineering research, and aims to become a global leader in the field.

“The accumulative amount of financing in the gene therapy field in China has exceeded $3.3 billion. Also, according to a Frost & Sullivan study, it is estimated that by 2025, gene therapy will reach a scale of nearly $17.89 billion in China,” said Fiona Gao, founding partner of Chinsiders.

Gene-edited trees are more sustainable and can boost fibre production

Scientists have used CRISPR gene editing to reduce the lignin content in poplar trees by as much as 50%, offering a potentially more sustainable and efficient method of fibre production.

Lignin is a complex organic polymer that is integral to the structure of cell walls in many types of plants, especially in wood and bark. It acts as a type of binder in these walls, giving wood its hardness and resistance to rot. Lignin is the second most abundant natural polymer in the world, next to cellulose, and makes up between 15% and 25% of the composition of wood.

Artificial Intelligence Unlocks New Possibilities in Anti-Aging Medicine

Posted by in categories: bioengineering, biotech/medical, information science, life extension, robotics/AI

A recent paper published in Nature Aging by researchers from Integrated Biosciences, a biotechnology company combining synthetic biology and machine learning.

Machine learning is a subset of artificial intelligence (AI) that deals with the development of algorithms and statistical models that enable computers to learn from data and make predictions or decisions without being explicitly programmed to do so. Machine learning is used to identify patterns in data, classify data into different categories, or make predictions about future events. It can be categorized into three main types of learning: supervised, unsupervised and reinforcement learning.
