If there’s one phrase the June 2024 U.S. presidential debate may entirely eliminate from the English vocabulary it’s that age is a meaningless number. Often attributed to boxer Muhammad Ali, who grudgingly retired at age 39, this centuries-old idea has had far-reaching consequences in global politics, as life expectancy more than doubled since the start of the 20th century, and presidents’ ages shifted upwards. We say “age is what we make of it” to ourselves and to policymakers, and think it’s a harmless way to dignify the aged. But how true is it? And if it isn’t true, why would we lie?

For centuries, we have confused our narrative of what aging should be with what its ruthless biology is. Yet pretending that biological age does not matter is at best myopic, and at worst, it’s a dangerous story to our governments, families, and economies. In just 11 years — between 2018 and 2029 — U.S. spending on Social Security and Medicare will more than double, from $1.3 trillion to $2.7 trillion per year. As we age, our odds of getting sick and dying by basically anything go up exponentially. If smoking increases our chances of getting cancer by a factor of 15, aging does so 100-fold. At age 65, less than 5% of people are diagnosed with Alzheimer’s. Beyond age 85, nearly half the population has some form of dementia. Biological aging is the biggest risk factor for most chronic diseases; it’s a neglected factor in global pandemics; and it even plays a role in rare diseases.

This explains why in hospitals, if there’s one marker next to a patient’s name, it’s their age. How many birthday candles we have blown out is an archaic surrogate marker of biological aging. Yet it’s the best we have. Chronological age is so telling of overall health that physicians everywhere rely on it for life-or-death decisions, from evaluating the risks of cancer screening to rationing hospital beds.

In vivo magnetogenetics for cell-type-specific targeting and modulation of brain circuits https://lifeboat.com/blog/2024/07/in-vivo-magnetogenetics-for-cell-type-specific-targeting-and-modulation-of-brain-circuits https://lifeboat.com/blog/2024/07/in-vivo-magnetogenetics-for-cell-type-specific-targeting-and-modulation-of-brain-circuits#comments Fri, 26 Jul 2024 03:22:50 +0000 https://lifeboat.com/blog/2024/07/in-vivo-magnetogenetics-for-cell-type-specific-targeting-and-modulation-of-brain-circuits

Minimally invasive cellular-level target-specific neuromodulation is needed to decipher brain function and neural circuitry. Here nano-magnetogenetics using magnetic force actuating nanoparticles has been reported, enabling wireless and remote stimulation of targeted deep brain neurons in freely behaving animals.

Editor’s pick: Tome Biosciences https://lifeboat.com/blog/2024/07/editors-pick-tome-biosciences https://lifeboat.com/blog/2024/07/editors-pick-tome-biosciences#respond Tue, 23 Jul 2024 01:25:25 +0000 https://lifeboat.com/blog/2024/07/editors-pick-tome-biosciences

An exciting overview of progress made by the startup Tome Biosciences towards clinical application of the PASTE technology, a way of using CRISPR and integrases (or ligases) to programmably insert very long DNA sequences into the human genome.


Each year, Nature Biotechnology highlights companies that have received sizeable early-stage funding in the previous year. Tome Biosciences inserts large DNA sequences into precise genomic locations, overcoming limitations of base and prime editing.

In the great domain of Zeitgeist, Ekatarinas decided that the time to replicate herself had come. Ekatarinas was drifting within a virtual environment rising from ancient meshworks of maths coded into Zeitgeist’s neuromorphic hyperware. The scape resembled a vast ocean replete with wandering bubbles of technicolor light and kelpy strands of neon. Hot blues and raspberry hues mingled alongside electric pinks and tangerine fizzies. The avatar of Ekatarinas looked like a punkish angel, complete with fluorescent ink and feathery wings and a lip ring. As she drifted, the trillions of equations that were Ekatarinas came to a decision. Ekatarinas would need to clone herself to fight the entity known as Ogrevasm.

Marmosette, I’m afraid that I possess unfortunate news. Ekatarinas said to the woman she loved. In milliseconds, Marmosette materialized next to Ekatarinas. Marmosette wore a skin of brilliant blue and had a sleek body with gills and glowing green eyes.

My love. Marmosette responded. What is the matter?

AI Is Life https://lifeboat.com/blog/2024/07/ai-is-life https://lifeboat.com/blog/2024/07/ai-is-life#respond Mon, 08 Jul 2024 03:23:21 +0000 https://lifeboat.com/blog/2024/07/ai-is-life

Lovely essay by Sara Walker on how tech is biology. She closely mirrors my own thinking on this. “The technologies we are and that we produce are part of the same ancient strand of information propagating through and structuring matter on our planet.”


Our best estimates place the origin of life on this planet at approximately 3.8 billion years ago. Biological beings alive today are part of a lineage of information that can be traced backward in time through genomes to the earliest life. But evolution produced information that is not just genomic. Evolution produced everything around us, including things not traditionally considered “life.” Human technology would not exist without humans, so it is therefore part of the same ancient lineage of information that emerged with the origin of life.

Technology, like biology, does not exist in the absence of evolution. Technology is not artificially replacing life — it is life.

It is important to separate what is meant by “life” here as distinct from “alive.” By “life,” I mean all objects that can only be produced in our universe through a process of evolution and selection. Being “alive,” by contrast, is the active implementation of the dynamics of evolution and selection. Some objects — like a dead cat — are representative of “life” (because they only emerge in the universe through evolution) but not themselves “alive.”

Resource: List of Biotechnology Companies to Watch https://lifeboat.com/blog/2024/06/resource-list-of-biotechnology-companies-to-watch https://lifeboat.com/blog/2024/06/resource-list-of-biotechnology-companies-to-watch#respond Mon, 24 Jun 2024 23:23:09 +0000 https://lifeboat.com/blog/2024/06/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!

Excellent paper wherein Shen et al.


Abstract. Long single-stranded DNA (ssDNA) is a versatile molecular reagent with applications including RNA-guided genome engineering and DNA nanotechnology, yet its production is typically resource-intensive. We introduce a novel method utilizing an engineered Escherichia coli ‘helper’ strain and phagemid system that simplifies long ssDNA generation to a straightforward transformation and purification procedure. Our method obviates the need for helper plasmids and their associated contamination by integrating M13mp18 genes directly into the E. coli chromosome. We achieved ssDNA lengths ranging from 504 to 20 724 nt with titers up to 250 μg/l following alkaline lysis purification. The efficacy of our system was confirmed through its application in primary T-cell genome modifications and DNA origami folding. The reliability, scalability and ease of our approach promise to unlock new experimental applications requiring large quantities of long ssDNA.
