Doctors use CRISPR gene editing inside a person’s body for first time

Posted by in categories: bioengineering, biotech/medical

Scientists say they have used the gene editing tool CRISPR inside someone’s body for the first time, a new frontier for efforts to operate on DNA, the chemical code of life, to treat diseases.

A patient recently had it done at the Casey Eye Institute at Oregon Health & Science University in Portland for an inherited form of blindness, the companies that make the treatment announced Wednesday. They would not give details on the patient or when the surgery occurred.

It may take up to a month to see if it worked to restore vision. If the first few attempts seem safe, doctors plan to test it on 18 children and adults.

Our Genetic Future Is Coming… Faster Than We Think

If there was a public vote about human gene enhancement, would you vote YES or NO?


Our species is on the cusp of a revolution that will change every aspect of our lives but we’re hardly talking about it.

Is Sex for Reproduction About to Become Extinct?

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

As the coming genetic revolution plays out, we’ll still have sex for most of the same reasons we do today. But we’ll increasingly not do it to procreate.


Another rocket booster will be the application of gene editing technologies like CRISPR to edit the genomes of pre-implanted embryos or of the sperm and eggs used to create them. Just this week, Chinese researchers announced they had used CRISPR to edit the CCR5 gene in the pre-implanted embryos of a pair of Chinese twins to make them immune to HIV, the first ever case of gene editing humans and a harbinger of our genetically engineered future. The astounding complexity of the human genome will put limits on our ability to safely make too many simultaneous genetic changes to human embryos, but our ability and willingness to make these types of alterations to our future children will grow over time along with our knowledge and technological ability.

New platform for engineering ribosomes to ‘cook new cuisines’

Posted by in categories: bioengineering, biotech/medical

Synthetic biology researchers at Northwestern University have developed a system that can rapidly create cell-free ribosomes in a test tube, then select the ribosome that can perform a certain function.

The system, called synthesis and evolution (RISE), is an important step toward using ribosomes beyond their natural capabilities. The key feature of RISE is the ability to evolve ribosomes without cell viability constraints. The result could be new ways to synthesize materials, like nylon, or therapies, like that could address rising antibiotic resistance.

“Ribosomes have an extraordinary capability as the protein synthesis machinery of the cell,” said Michael Jewett, Walter P. Murphy Professor of Chemical and Biological Engineering and director of the Center for Synthetic Biology at Northwestern’s McCormick School of Engineering, who led the research. “But to synthesize proteins beyond those found in nature, we have to design and modify the ribosome to work with non-natural substrates. Developing ribosomes in vitro is an important part of that system, and we are very excited to have this new capability.”

Meet Xenobot, an Eerie New Kind of Programmable Organism

Posted by in categories: bioengineering, information science

Under the watchful eye of a microscope, busy little blobs scoot around in a field of liquid—moving forward, turning around, sometimes spinning in circles. Drop cellular debris onto the plain and the blobs will herd them into piles. Flick any blob onto its back and it’ll lie there like a flipped-over turtle.

Their behavior is reminiscent of a microscopic flatworm in pursuit of its prey, or even a tiny animal called a water bear—a creature complex enough in its bodily makeup to manage sophisticated behaviors. The resemblance is an illusion: These blobs consist of only two things, skin cells and heart cells from frogs.

Writing today in the Proceedings of the National Academy of Sciences, researchers describe how they’ve engineered so-calleds (from the species of frog, Xenopus laevis, whence their cells came) with the help of evolutionary algorithms. They hope that this new kind of organism—contracting cells and passive cells stuck together—and its eerily advanced behavior can help scientists unlock the mysteries of cellular communication.

Should we edit our DNA? An imagined future of gene editing – video

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

There are decisions being made right now that could have an effect on global populations for generations to come. As part of this project, we commissioned an artist to investigate some of the themes raised in the podcasts. This work of fiction imagines a future where gene editing has become mainstream and discusses the moral, ethical and political divides that this might create.

Building a Positive Genetic Future for All

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

Nearly every day, new discoveries are pushing the genetics revolution ever-forward. It’s hard to imagine it’s been only a century and a half since Gregor Mendl experimented with his peas, six decades since Watson and Crick identified the double helix, fourteen years since the completion of the human genome project, and five years since scientists began using CRISPR-cas9 for precision gene editing. Today, these tools are being used in ways that will transform agriculture, animal breeding, healthcare, and ultimately human evolution.

Common practices like in vitro fertilization (IVF) and preimplantation embryo selection make human genetic enhancement possible today. But as we learn more and more about what the genome does, we will be able to make increasingly more informed decisions about which embryos to implant in IVF in the near term and how to manipulate pre-implanted embryos in the longer-term. In our world of exponential scientific advancement, the genetic future will arrive far faster than most people currently understand or are prepared for.
