CRISPR-Cas9: Reagent selection to experimental optimization

Posted by in categories: bioengineering, biotech/medical

A webinar presented by: James Goldmeyer, PhD

The use of CRISPR-Cas9 for gene editing has opened up many new avenues for scientific exploration around gene function. The rapid expansion of the field has led to a wide range of technology formats for use in both gene knockout and precision knockin genome engineering experiments. The seemingly ever-increasing toolset has also led to a widening knowledge gap for newcomers to the field to overcome in determining the proper reagents for performing experiments.

During this webinar we will discuss the basics of CRISPR-Cas9 gene editing and the key criteria and decision points in selecting reagents based on your desired application. We will review all types of guide RN…A and Cas9 nuclease formats and discuss the advantages and disadvantages of each.

Researchers improve accuracy of synthetic clock

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

Nice.


(Phys.org)—A team of researchers with Harvard University and the University of Cambridge has successfully improved the accuracy of a synthetic clock known as a repressilator. In their paper published in the journal Nature, the team describes the steps they took to reduce the amount of noise in the biological system and how well it worked. Xiaojing Gao and Michael Elowitz with the California Institute of Technology offer a News & Views piece on the work done by the team and explain how their results could improve understanding of natural gene circuits.

Scientists have noted the high precision that some living cells demonstrate in keeping track of time, such as those that are part of the circadian clock, and have tried to duplicate the process. Sixteen years ago, Michael Elowitz and Stanislas Leibler developed what is now known as the repressilator—a synthetic oscillating genetic circuit. Their results demonstrated that it was possible for genetic circuits to be designed and built in the lab. The resulting circuit functioned, but was noisy, and therefore much less accurate than natural cell clocks. In this new effort, the researchers improved several of the design of the repressilator, each greatly reducing the amount of noise, and in so doing, increased the precision.

With New Program, DARPA To Encourage Safety “Brakes” For Gene Editing

Posted by in categories: bioengineering, biotech/medical, finance, genetics, health, military

Xconomy National —

Drugs that use molecular scissors to snip out or replace defective genes. Altered mosquitoes meant to sabotage entire disease-carrying populations. Both are potential uses of genome editing, which thanks to the CRISPR-Cas9 system has spread throughout the world’s biology labs and is now on the doorstep of the outside world. But with its first applications could also come unintended consequences for human health and the environment. The U.S. Defense Advanced Research Projects Agency—a famed military R&D group—wants to finance safety measures for the new gene-editing age.

The idea for the funding program, called Safe Genes, is to get out ahead of problems that could bring the field to a screeching halt. “We should couple innovation with biosecurity,” DARPA program manager Renee Wegrzyn, said Tuesday at the SynBioBeta conference in South San Francisco. “We need new safety measures that don’t slow us down. You have brakes in your car so that you can go fast but can stop when you need to.”

(Im)mortality: Researchers Find That Human Lifespan Has A Max Limit

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

In Brief.

  • New research concludes that human lifespan has already reached its peak of 125 years.
  • The research does not take into account synthetic biology and advancements in biotech that could extend lifespans further.

Scientists at the Albert Einstein College of Medicine assert that they have discovered the maximum lifespan of human beings, and it’s a range we may no longer be able to exceed. Dr. Jan Vijg, professor of ophthalmology and visual sciences at Einstein, lead the research, which was published online today in the journal Nature.

CRISPR Cas9: Will it Cure Aging? — Talk

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

How we can use CRISPR/Cas9 to treat the processes of aging.


Oliver Medvedik, Cofounder of the Life Extension Advocacy Foundation and the Lifespan.io Crowdfunding platform, discusses the CRISPR/Cas9 gene editing system in depth and highlights how it may be used to help overcome the diseases and disabilities of aging. He also gives an overview of other promising areas in aging research, such as senescent cell-clearing drugs, or “senolytics”, and “augmentive” compounds that may help restore the body to youthful functionality.

Bioengineered bacteria could be used to 3D print food, medicine, and tools on Mars

Posted by in categories: 3D printing, bioengineering, biotech/medical, food, solar power, space travel, sustainability

Just like checking your bag on a commercial airline, space travel comes with some pretty big weight restrictions. How big? According to estimates, reaching space costs a whopping $10,000 per pound, which means that every ounce saved has a big impact on the bottom line.

That’s where a group of Danish researchers comes in. The team is working on a synthetic biology project called CosmoCrops, which hopes to use bacteria to make it possible to 3D print everything needed for a respectable space mission, using a cutting-edge co-culturing system. And it could even make life better for those of us back on Earth in the process.

“We are trying to make space exploration cheaper, because many inventions we use in our daily life were invented because of space exploration, like Velcro and solar energy,” Joachim Larsen, one of the students working on the project, told Digital Trends. “The way we want to achieve this is to [be] able to produce everything from food to medicine and bioplastic for 3D printers out in space — making the space rocket a lot lighter.”
