The CRISPR-Cas9 system has revolutionized genetic manipulations and made gene editing simpler, faster and easily accessible to most laboratories.

To its recognition, this year, the French-American duo Emmanuelle Charpentier and Jennifer Doudna have been awarded the prestigious Nobel Prize for chemistry for CRISPR.

Experts say that COVID-19 almost certainly arose naturally, rather than being bioengineered.

But that doesn’t mean the next pandemic won’t involve a deadly virus designed by an adversary, as distinguished fellow at Harvard Law Vivek Wadhwa argues in a new essay for Foreign Policy.

“It is now too late to stop the global spread of these technologies — the genie is out of the bottle,” he wrote. “We must treat the coronavirus pandemic as a full dress rehearsal of what is to come — unfortunately, that includes not only viruses that erupt from nature, but also those that will be deliberately engineered by humans.”

One of the most remarkable recent advances in biomedical research has been the development of highly targeted gene-editing methods such as CRISPR that can add, remove, or change a gene within a cell with great precision. The method is already being tested or used for the treatment of patients with sickle cell anemia and cancers such as multiple myeloma and liposarcoma, and today, its creators Emmanuelle Charpentier and Jennifer Doudna received the Nobel Prize in chemistry.

While gene editing is remarkably precise in finding and altering genes, there is still no way to target treatment to specific locations in the body. The treatments tested so far involve removing blood stem cells or immune system T cells from the body to modify them, and then infusing them back into a patient to repopulate the bloodstream or reconstitute an immune response—an expensive and time-consuming process.

Building on the accomplishments of Charpentier and Doudna, Tufts researchers have for the first time devised a way to directly deliver gene-editing packages efficiently across the blood brain barrier and into specific regions of the brain, into immune system cells, or to specific tissues and organs in mouse models. These applications could open up an entirely new line of strategy in the treatment of neurological conditions, as well as cancer, infectious disease, and autoimmune diseases.

Perhaps in the future, gene editing may allow retinal regeneration in humans to reverse age-related vision deterioration.

Damage to the retina is the leading cause of blindness in humans, affecting millions of people around the world. Unfortunately, the retina is one of the few tissues we humans can’t grow back.

Unlike us, other animals such as zebrafish are able to regenerate this tissue that’s so crucial to our power of sight. We share 70 percent of our genes with these tiny little zebrafish, and scientists have just discovered some of the shared genes include the ones that grant zebrafish the ability to grow back their retinas.

Although it’s clearly NOT the approach taken for ultracold vitrification of patients undergoing life extension cryonization. (ULTRA🥶COLD being the exact opposite of ULTRA-BLOODY-H🥵T, obviously!)

Still, given the vast number of scientific and engineering discoveries and creations born on the backs of unexpected results, accidental discoveries, and outright screw up, it might have very useful data that has practical applications that would never otherwise have even been considered.

Italian scientists found intact brain cells in a man who was killed during the eruption of Mount Vesuvius in 79 AD.

Synthetic biology startups raised some $3 billion through the first half of 2020, up from $1.9 billion for all of 2019, as the field brings the science of engineering to the art of life.

The big picture: Synthetic biologists are gradually learning how to program the code of life the way that computer experts have learned to program machines. If they can succeed — and if the public accepts their work — synthetic biology stands to fundamentally transform how we live.

What’s happening: SynBioBeta, synthetic biology’s major commercial conference, launched on Tuesday, virtually bringing together thousands of scientists, entrepreneurs, VCs and more to discuss the state of the field.

Two active genetics strategies help address concerns about gene-drive releases into the wild.

In the past decade, researchers have engineered an array of new tools that control the balance of genetic inheritance. Based on CRISPR technology, such gene drives are poised to move from the laboratory into the wild where they are being engineered to suppress devastating diseases such as mosquito-borne malaria, dengue, Zika, chikungunya, yellow fever and West Nile. Gene drives carry the power to immunize mosquitoes against malarial parasites, or act as genetic insecticides that reduce mosquito populations.

Although the newest gene drives have been proven to spread efficiently as designed in laboratory settings, concerns have been raised regarding the safety of releasing such systems into wild populations. Questions have emerged about the predictability and controllability of gene drives and whether, once let loose, they can be recalled in the field if they spread beyond their intended application region.

David Sinclair wants to slow down and ultimately reverse aging. Sinclair sees aging as a disease and he is convinced aging is caused by epigenetic changes, abnormalities that occur when the body’s cells process extra or missing pieces of DNA. This results in the loss of the information that keeps our cells healthy. This information also tells the cells which genes to read. David Sinclair’s book: “Lifespan, why we age and why we don’t have to”, he describes the results of his research, theories and scientific philosophy as well as the potential consequences of the significant progress in genetic technologies.

At present, researchers are only just beginning to understand the biological basis of aging even in relatively simple and short-lived organisms such as yeast. Sinclair however, makes a convincing argument for why the life-extension technologies will eventually offer possibilities of life prolongation using genetic engineering.
