E. coli rewired to control growth as experts let them make proteins for medicine

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

Experts have equipped biotech workhorse bacteria with feedback control mechanism to balance growth with making protein products.

Medicines like insulin and interferon are manufactured using genetically engineered bacteria, such as E. coli. E. coli grow quickly and can be given DNA that instructs them to make proteins used in medicines and other materials.

However, the extra burden of producing new proteins hampers bacterial growth, which slows production. Solving this problem is an area of great interest for biotechnology and synthetic biology.

Deniers and Critics of AI Will Only Be Left Behind

Posted by in categories: biotech/medical, ethics, genetics, geopolitics, health, policy, robotics/AI, transhumanism

This month I’m participating in Cato Institute’s Cato Unbound discussion. Cato is one of the world’s leading think tanks. Here’s my new and second essay for the project:


Professor David D. Friedman sweeps aside my belief that religion may well dictate the development of AI and other radical transhumanist tech in the future. However, at the core of a broad swath of American society lies a fearful luddite tradition. Americans—including the U.S. Congress, where every member is religious—often base their life philosophies and work ethics on their faiths. Furthermore, a recent Pew study showed 7 in 10 Americans were worried about technology in people’s bodies and brains, even if it offered health benefits.

It rarely matters what point in American history innovation has come out. Anesthesia, vaccines, stem cells, and other breakthroughs have historically all battled to survive under pressure from conservatives and Christians. I believe that if formal religion had not impeded our natural secular progress as a nation over the last 250 years, we would have been much further along in terms of human evolution. Instead of discussing and arguing about our coming transhumanist future, we’d be living in it.

Interventions to extend healthspan and lifespan 2018- Dr. Andrei Gudkov

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

Elena Milova is at the Interventions to extend healthspan and lifespan 2018 conference in Kazan this week. This is an important conference in the aging research field, and it includes a variety of leading experts giving talks about their research. One of these experts is Andrei Gudkov, and Elena had the opportunity to talk with him about his research.

Dr. Andrei V. Gudkov, Ph.D., D.Sci, is a Scientific Co-Founder of Cleveland Biolabs, Inc. and has been its Chief Scientific Officer since June 2003. Dr. Gudkov serves as Chief Scientific Officer and Founder at Everon Biosciences, Inc. He co-founded Mega Biotech & Electronics Co., Ltd. and serves as its Chief Scientific Officer. Dr. Gudkov serves as Senior Vice President of Basic Science at Roswell Park Cancer Institute. He has over 25 years of experience in biomedical research. Prior to 1990, he worked with the National Cancer Research Center in Moscow (USSR), where he led a broad research program focused on virology and cancer drug resistance.

In 1990, he re-established his lab at the University of Illinois at Chicago, where he became a tenured faculty member in the Department of Molecular Genetics. In 1999, he defined p53 as a major determinant of cancer treatment side effects and suggested this protein as a target for therapeutic suppression. In 2001, Dr. Gudkov moved his laboratory to the Lerner Research Institute at the Cleveland Clinic Foundation, where he served as Chairman of the Department of Molecular Biology and Professor of Biochemistry at Case Western Reserve University. He has served as a Director of Cleveland Biolabs, Inc. since June 2003.

Refining the Epigenetic Clock

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

A team of researchers, including professor Steve Horvath, the pioneer of the epigenetic clock, report in this new paper about an improved version of that clock [1]. His original epigenetic clock measures the age of a person by looking at DNA methylation patterns; these patterns correlate closely with the actual age of a person, with a margin of error of around two years or so.

Since the original clock was first created, work has continued on refining the process and how aging is measured. In terms of aging biomarkers, it is generally considered the gold standard, given how reliable it is as a way to determine biological age.

While chronological age is linked to the likelihood of us developing age-related diseases and dying, it is important to distinguish the difference between chronological age and biological age. Individuals of the same chronological age may not age in quite the same way or even at the same rate, showing differences in their susceptibility to different age-related diseases.

Researchers use CRISPR to edit DNA outside of the cell for the first time

Posted by in categories: bioengineering, biotech/medical, genetics, health

Wilmington, DE, April 19, 2018 — Scientists at Christiana Care Health System’s Gene Editing Institute have developed a potentially breakthrough CRISPR gene-editing tool. It could allow researchers to take fragments of DNA extracted from human cells, put them into a test tube, and quickly and precisely engineer multiple changes to the genetic code, according to a new study published today in the CRISPR Journal.

Investigators at the Gene Editing Institute, which is part of the Helen F. Graham Cancer Center & Research Institute at Christiana Care, said their new “cell-free” CRISPR technology is the first CRISPR tool capable of making multiple edits to DNA samples “in vitro,” which means in a test tube or petri dish. The advance could have immediate value as a diagnostic tool, replicating the exact genetic mutations found in the tumors of individual cancer patients. Mutations that cause cancer to spread can differ from patient to patient, and being able to quickly identify the correct mutation affecting an individual patient can allow clinicians to implement a more targeted treatment strategy.

“With this new advance, we should be able to work with laboratory cultures and accomplish gene edits in less than a day, significantly reducing the time required for diagnostics compared to other CRISPR tools, and with much greater precision,” said Eric Kmiec, Ph.D., director of the Gene Editing Institute and principal author of the study. “This is particularly important for diagnostics linked to cancer care where time is critical.”

Natural Causes

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

“Old age isn’t a battle,” she says, quoting Philip Roth, “old age is a massacre.” In the past few years, she has given up on screenings and scans. Not that she is lazy or suicidal. But at 76, she considers herself old enough to die. All the self-help books aimed at her age group tell her otherwise; they talk of “active ageing”, “productive ageing”, “anti-ageing”, even “reverse-ageing”, with a long life promised to anyone who makes an effort, regardless of factors such as genetics or poverty. But to her, ageing is “an accumulation of disabilities”, which no amount of physical activity or rigorous self-denial can prevent. If she has symptoms, she’ll have them investigated. But when a doctor tells her there could be an undetected problem of some kind, she won’t play along.


A great iconoclast has written a polemic about ageing that sends up New Age platitudes and is full of scepticism of the wellness industry.

Peripheral Elevation of a Klotho Fragment Enhances Brain Function and Resilience in Young, Aging, and α-Synuclein Transgenic Mice

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

Peripheral Elevation of a #Klotho Fragment Enhances Brain Function and Resilience in Young, Aging, and α-Synuclein Transgenic Mice.


Klotho is a longevity factor associated with cognitive enhancement when genetically and widely overexpressed over the lifetime of mice. Leon et al. show that peripheral delivery of a klotho fragment, αKL-F, acutely enhances cognition and neural resilience in young, aging, and disease model mice, establishing its therapeutic relevance and dissecting its underlying mechanisms.
