Surprise! Our Bodies Have Been Hiding a Trojan Horse for Gene Therapy

Posted by in categories: biotech/medical, genetics

The problem? Our bodies aren’t big fans of foreign substances—particularly ones that trigger an undesirable immune response. What’s more, these delivery systems aren’t great with biological zip codes, often swarming the entire body instead of focusing on the treatment area. These “delivery problems” are half the battle for effective genetic medicine with few side effects.

“The biomedical community has been developing powerful molecular therapeutics, but delivering them to cells in a precise and efficient way is challenging,” said Zhang at the Broad Institute, the McGovern Institute, and MIT.

Researchers develop program to read any genome sequence and decipher its genetic code

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

Yekaterina “Kate” Shulgina was a first year student in the Graduate School of Arts and Sciences, looking for a short computational biology project so she could check the requirement off her program in systems biology. She wondered how genetic code, once thought to be universal, could evolve and change.

That was 2016 and today Shulgina has come out the other end of that short-term project with a way to decipher this genetic mystery. She describes it in a new paper in the journal eLife with Harvard biologist Sean Eddy.

The report details a new computer program that can read the of any organism and then determine its genetic code. The program, called Codetta, has the potential to help scientists expand their understanding of how the genetic code evolves and correctly interpret the genetic code of newly sequenced .

Making science serve humanity: Jennifer Doudna, PhD, says CRISPR gene-editing technology should be accessible to all

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

The path that led Jennifer Doudna, PhD, and her colleagues to the development of CRISPR, the gene-editing tool that has revolutionized science and earned her a Nobel Prize, started with their deep curiosity and drive to understand how the most basic building blocks of life function.

When Doudna first decided to investigate precisely what systems bacteria use to adapt their immune systems to fight off viral infections, she had little expectation that the findings would ultimately provide the key to technology that could be used to safely alter genetic code.

“All of us [on the research team] realized that what had started as a fundamental research question was morphing into a very different kind of project; namely, one with enormous technical potential and also risks and opportunities that we had not appreciated when we started the work,” Doudna explained during a conversation with J. Larry Jameson, MD, PhD, chair of the AAMC Board of Directors and executive vice president of the University of Pennsylvania Health System, at the opening plenary of Learn Serve Lead 2021: The Virtual Experience, on Monday, Nov. 8.

Powerful New Tool Can Peer Into the Vast Genetic Library Inside of Your Cells

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

The human genome can be thought of as a massive library, containing over 20,000 different “instruction manuals”: your genes. For example, there are genes which contain information to build a brain cell, a skin cell, a white blood cell, and so on. There are even genes that contain information about regulating the genome itself—like books that explain how to organize a library. The ability to regulate gene expression —in other words, the cell’s ability to turn various constellations of genes on or off—is the basis of why different cells (such as a muscle cell or a brain cell) have different forms and functions.

For any library to be useful to a reader, it needs to be organized in an easily searchable way. For example, all the books pertaining to world history may be on one shelf, whereas the cookbooks may be in an entirely different section of the library. In a cellular nucleus, there is over six feet of genetic material packed into a space 50 times smaller than the width of a human hair. How is the “library” in the nucleus organized? When a cell needs to regulate certain genes, how does the cellular machinery find the right ones amongst 20,000 others?

A new paper from the laboratory of Mitchell Guttman, professor of biology, uses a powerful new tool that can peer into the world of the cell’s genetic material (DNA.

Cellular aging: A basic paradox elucidated

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

In a study published in Nucleic Acids Research, the team of cancer researcher Francis Rodier, an Université de Montréal professor, shows for the first time that cellular senescence, which occurs when aging cells stop dividing, is caused by irreversible damage to the genome rather than simply by telomere erosion.

This discovery goes against the scientific model most widely adopted in the last 15 years, which is based on one principle: telomeres, caps located at the ends of chromosomes whose purpose is to protect genetic information, erode with each cell division. When they get too short, they tell the cell to stop dividing, thus preventing damage to its DNA. Made dormant, the cell enters senescence.

For this model to be valid, the inactivation of a single should be sufficient to activate the senescence program. Rodier’s laboratory and many others had already observed that several dysfunctional telomeres were necessary.

If Female Condors Can Reproduce Without An Assist From Males, Why Can’t Humans And All Other Animals? 15 Points That Help Explain ‘Parthenogenesis.’

Posted by in categories: biotech/medical, genetics

1. In a paper published on October 28 2021, in the peer-reviewed Journal of Heredity, scientists from the San Diego Zoo revealed that at least two California condors born over the last 40 years or so are biologically fatherless. A genetic database maintained since the 1980s showed no trace whatsoever of paternal genes in their DNA.

2. No one knows whether reproducing asexually is a new talent for California condors. Maybe the species has always been capable of it. California condors almost went extinct in the 1980s, and they are still endangered. Because of this, the number of animals in the genetic database is too small for anyone to address the question reasonably.

THIS PILL makes you Live Forever — The Government’s Longevity Project

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

The USA Government is secretly working on a real Anti Aging Pill which aims to extend peoples lifespan and improve their health. This new longevity research project even made Aubrey De Grey interested as he said in an interview. Although he’s working on other kinds of medication to make people live forever or at least to stop peoples aging.

Dr. David Sinclair’s main research interest is the epigenetics of aging, with a focus on epigenetic reprogramming of aging, NAD+ metabolism and sirtuins, and NAD+ precursors like NR and NMN. David Sinclair is also working on supplements that are supposed to slow down the aging process.

Plans Of A Technocratic Elite: ‘The Great Reset’ Is Not A Conspiracy Theory

Posted by in categories: 3D printing, biotech/medical, genetics, information science, internet, nanotechnology, quantum physics, Ray Kurzweil, robotics/AI, singularity, transhumanism

According to Klaus Schwab, the founder and executive chair of the World Economic Forum (WEF), the 4-IR follows the first, second, and third Industrial Revolutions—the mechanical, electrical, and digital, respectively. The 4-IR builds on the digital revolution, but Schwab sees the 4-IR as an exponential takeoff and convergence of existing and emerging fields, including Big Data; artificial intelligence; machine learning; quantum computing; and genetics, nanotechnology, and robotics. The consequence is the merging of the physical, digital, and biological worlds. The blurring of these categories ultimately challenges the very ontologies by which we understand ourselves and the world, including “what it means to be human.”

The specific applications that make up the 4-R are too numerous and sundry to treat in full, but they include a ubiquitous internet, the internet of things, the internet of bodies, autonomous vehicles, smart cities, 3D printing, nanotechnology, biotechnology, materials science, energy storage, and more.

While Schwab and the WEF promote a particular vision for the 4-IR, the developments he announces are not his brainchildren, and there is nothing original about his formulations. Transhumanists and Singularitarians (or prophets of the technological singularity), such as Ray Kurzweil and many others, forecasted these and more revolutionary developments,. long before Schwab heralded them. The significance of Schwab and the WEF’s take on the new technological revolution is the attempt to harness it to a particular end, presumably “a fairer, greener future.”
