Octopuses are like aliens living among us — they do a lot of things differently from land animals, or even other sea creatures. Their flexible tentacles taste what they touch and have minds of their own. Octopuses’ eyes are color-blind, but their skin can detect light on its own (SN: 6/27/15, p. 10). They are masters of disguise, changing color and skin textures to blend into their surroundings or scare off rivals. And to a greater extent than most creatures, octopuses squirt the molecular equivalent of red ink over their genetic instructions with astounding abandon, like a copy editor run amok.

These edits modify RNA, the molecule used to translate information from the genetic blueprint stored in DNA, while leaving the DNA unaltered.

B cells of our immune system have the incredible capability to generate up to 10,000,000,000,000 different antibodies. How do they do it? | Genetics And Genomics.

The new tool has the capacity to undertake strand-specific gene editing without any cuts.

Chinese researchers claim to have created a new gene-editing technique called CyDENT that is more effective than Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) technology.

This is according to a report by the South China Morning Post (SCMP) published on Saturday.

Gene therapy for longevity and targeted disease treatment.

Gene therapy has the power to extend healthy longevity and treat a litany of organ-specific conditions.

The eye is one outstanding candidate.

In the form of DNADNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

The organism fared better at converting organic waste to electricity than even some famous and exotic electricity producing microbes.

Scientists at the Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland have successfully engineered E.coli.

Escherichia coli, commonly known as E.coli, is a rod-shaped bacterium commonly found in the lower gut of organisms. However, it has become a favorite of microbial researchers worldwide for the ease with which its genetic structure can be manipulated. It has, therefore, become an indispensable part of research and industrial projects.

This is a big deal, kids.

For the past five years, Silicon Valley biotech Rejuvenation Technologies has been quietly working on a therapeutic platform to extend telomeres in the human body, with the goal of boosting longevity and healthspan. Yesterday, the company emerged from stealth with a healthy seed funding round of $10.6 million, led by Khosla Ventures.

Rejuvenation has developed a synthetic mRNA-based approach to restoring telomeres to a “healthy length” – capable of reversing a decade of telomere shortening in a single dose. The mRNA produces telomerase, an enzyme that plays a critical role in maintaining the length of telomeres. Following positive preclinical results in lung and liver disease indications, the company is now preparing the path towards its first in-human trials.

The researchers claim it’s the first “complete” embryo model for simulating all the important components that form in the early embryo.

The science of baby-making is clear. A sperm cell (which contains genetic material from the father) and an egg cell (which contains genetic material from the mother) must fuse in order for a human embryo to develop.

However, science and technology are constantly improving in the fields of embryology and stem cell research.
