CRISPR-induced immune diversification in host-virus populations

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

Just like humans, microbes have equipped themselves with tools to recognize and defend themselves against viral invaders. In a continual evolutionary battle between virus and host, CRISPR-Cas act as a major driving force of strain diversity in host-virus systems.

A new study led by Professor of Life Sciences Shai Pilosof (Ben-Gurion University of the Negev, Beer-Sheva, Israel), Professor of Microbiology Rachel Whitaker (University of Illinois Urbana-Champaign), and Professor of Ecology and Evolution Mercedes Pascual (University of Chicago) highlights the role of diversified immunity in mediating -pathogen interactions and its eco-evolutionary dynamics. The study also included Professor of Bioengineering and Bliss Faculty Scholar Sergei Maslov (University of Illinois Urbana-Champaign), Sergio A. Alcal´a-Corona (University of Chicago), and Ph.D. graduate students Ted Kim and Tong Wang (University of Illinois Urbana-Champaign).

Their findings were reported in the journal Nature Ecology & Evolution.

Autopsies Show Microplastics in Major Human Organs

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

It looks like micro-plastics are now found inside human bodies.


Researchers found evidence of plastic contamination in tissue samples taken from the lungs, liver, spleen and kidneys of donated human cadavers.

“We have detected these chemicals of plastics in every single organ that we have investigated,” said senior researcher Rolf Halden, director of the Arizona State University (ASU) Biodesign Center for Environmental Health Engineering.

[Burning Issue] CRISPR Technology and Associated Concerns

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

We ask students to login via google as we share a lot of our content over google drive. To access the same, a google account is a must.


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.

Harvard Fellow: Next Pandemic Could Be Engineered by Terrorists

Posted by in categories: bioengineering, biotech/medical

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.”

Engineers create nanoparticles that deliver gene-editing tools to specific tissues and organs

Posted by in categories: bioengineering, biotech/medical, chemistry, genetics, nanotechnology, neuroscience

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 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 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 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.

Some Fish Can Regenerate Their Eyes. Turns Out, Mammals Have Those Genes Too

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

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.

Volcanic eruption turned man’s brain into glass, ‘froze’ brain cells 2,000 years ago, scientists find

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

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 brings the hard science of engineering to the basics of life

Posted by in categories: bioengineering, biological, computing, science

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.

New Genetic Systems Created by Biologists to Neutralize Gene Drives

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

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.
