CRISPR-COPIES: New Tool Accelerates and Optimizes Genome Editing

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

CRISPR/Cas systems have undergone tremendous advancement in the past decade. These precise genome editing tools have applications ranging from transgenic crop development to gene therapy and beyond. And with their recent development of CRISPR-COPIES, researchers at the Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) are further improving CRISPR’s versatility and ease of use.

“CRISPR-COPIES is a tool that can quickly identify appropriate chromosomal integration sites for genetic engineering in any organism,” said Huimin Zhao, CABBI Conversion Theme Leader and Steven L. Miller Chair of Chemical and Biomolecular Engineering (ChBE) at the University of Illinois. “It will accelerate our work in the metabolic engineering of non-model yeasts for cost-effective production of chemicals and biofuels.”

Gene editing has revolutionized scientists’ capabilities in understanding and manipulating genetic information. This form of genetic engineering allows researchers to introduce new traits into an organism, such as resistance to pests or the ability to produce a valuable biochemical.

Debate simmers over when doctors should declare brain death

Posted by in categories: bioengineering, biotech/medical, ethics, law, neuroscience

Benjamin Franklin famously wrote: “In this world nothing can be said to be certain, except death and taxes.” While that may still be true, there’s a controversy simmering today about one of the ways doctors declare people to be dead.

Bioethicists, doctors and lawyers are weighing whether to redefine how someone should be declared dead. A change in criteria for brain death could have wide-ranging implications for patients’ care.

3D-Printed Electronic Skin provides promise for Human-Machine Interaction

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

With more than 1,000 nerve endings, human skin is the brain’s largest sensory connection to the outside world, providing a wealth of feedback through touch, temperature and pressure. While these complex features make skin a vital organ, they also make it a challenge to replicate.

By utilizing nanoengineered hydrogels that exhibit tunable electronic and thermal biosensing capabilities, researchers at Texas A&M University have developed a 3D-printed electronic skin (E-skin) that can flex, stretch and sense like human skin.

“The ability to replicate the sense of touch and integrate it into various technologies opens up new possibilities for human-machine interaction and advanced sensory experiences,” said Dr. Akhilesh Gaharwar, professor and director of research for the Department of Biomedical Engineering. “It can potentially revolutionize industries and improve the quality of life for individuals with disabilities.”

This new 3D printing method could solve the organ transplantation crisis

Posted by in categories: 3D printing, bioengineering, biotech/medical

In the United States, the shortage of available organs for transplantation remains a critical issue, with over 100,000 individuals currently on the waiting list. The demand for organs, including hearts, kidneys, and livers, significantly outweighs the available supply, leading to prolonged waiting times and often, devastating consequences.

It is estimated that approximately 6,000 Americans lose their lives while waiting for a suitable donor organ every year.

Researchers at Carnegie Mellon University have developed a novel tissue engineering technique that aims to potentially bridge the gap between organ demand and availability, offering a beacon of hope.

Jennifer Doudna: Delivering the future of CRISPR-based genome editing

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

Nobel laureate details new applications at Kuh Distinguished Lecture.

Jennifer Doudna, Nobel laureate and Li Ka Shing Chancellor’s Chair and Professor in the Departments of Chemistry and of Molecular and Cell Biology, presented this year’s Ernest S. Kuh Distinguished Lecture, “Delivering the Future of CRISPR-Based Genome Editing,” on February 2 at UC Berkeley. The sold-out event — produced by Berkeley Engineering in collaboration with the Society of Women Engineers — marks the 11th talk in the lecture series, which features scientists and engineers tackling the world’s most pressing problems.

Doudna is known for developing CRISPR-Cas9, a groundbreaking technology that some call “genetic scissors.” With it, scientists can snip and edit DNA — the genetic code of life — unlocking remarkable possibilities in biology, including treatments for thousands of intractable diseases. This work has changed the course of genomics research, allowing scientists to rewrite DNA with unprecedented precision, and won Doudna and collaborator Emmanuelle Charpentier the 2020 Nobel Prize in Chemistry.

SynMoss project grows moss with partially synthetic genes

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

A Chinese team of life scientists, microbiologists, plant researchers and seed designers has developed a way to grow engineered moss with partially synthetic genes. In their project, reported in the journal Nature Plants, the group engineered a moss that is one of the first living things to have multiple cells carrying a partially artificial chromosome.

Several research projects have been working toward the goal of creating plants with synthetic —such plants could be programmed to produce more food, for example, or more oxygen, or to pull more from the air. Last year, one team of researchers developed a way to program up to half of the genome of yeast cells using synthetic genes.

In this new effort, the team in China upped the ante by replacing natural genes with genes created in a lab—moss is far more genetically complex than yeast. They call their project SynMoss.
