Gene Editing Just Got So Precise, Researchers Can Change Single Letters of DNA Code

MhAX, or Microhomology-Assisted eXcision.

Gene editing has the power to completely reshape our world.

It promises everything from fixing the genetic faults that lead to disease, to destroying disease-causing microbes, to improving the nutrition of the foods we eat and even resurrecting extinct species like the wooly mammoth — all largely thanks to the genetic editing tool CRISPR, which has both popularized this work and made it possible.

Now, researchers in Japan have developed a new gene editing technique that uses CRISPR alongside a DNA repair system to modify a single DNA base in the human genome, with what the team’s press release calls “absolute precision.”

Bioquark Inc. — Conferences on Death / Death Reversal — Ira Pastor

Two pivotal conferences on the topic of “death” coming up!!

First at the INSERM Liliane Bettencourt School on March 16–18 will be “Death: From Cells to Societies — Aging, Dying, and Beyond” -

Then, April 11–13 at Harvard Medical School, will be “Defining Death: Organ transplantation and the 50-year legacy of the Harvard report on brain death”

An important inflection point for all!!

New synthetic polymer kills antibiotic-resistant superbugs from the inside out

A research team composed of scientists from the Institute of Bioengineering and Nanotechnology (IBN) of the Agency for Science, Technology and Research (A*STAR) and IBM Research has produced a new synthetic molecule that can target and kill five multidrug-resistant bacteria. This synthetic polymer was found to be non-toxic and could enable entirely new classes of therapeutics to address the growing problem of antibiotic-resistant superbugs.

The synthetic molecules are called guanidinium-functionalized polycarbonates and were found to be both biodegradable and non-toxic to human cells. Essentially, the positively-charged synthetic polymer enters a living body and binds specifically to certain bacteria cells by homing in on a microbial membrane’s related negative charge. Once attached to the bacteria, the polymer crosses the cell membrane and triggers the solidification of proteins and DNA in the cell, killing the bacteria.
