Gene Editing Can Now Change An Entire Species Forever

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

In Brief CRISPR has opened up limitless avenues for genetic modification. From disease prevention to invasive species control, Jennifer Kahn discusses the discover, application, and implications of gene drives.

Jennifer Kahn, a science journalist for the New York Times, recently did a TED Talk in which she discussed the discovery, application, and implications of a CRISPR gene drive used to make mosquitoes resistant to malaria and other diseases like chikungunya, and Zika.

Real ‘Jurassic World’ Scientist Says We Could Bring Back Dinosaurs As Pets

Posted by in categories: bioengineering, entertainment

Paleontologist Jack Horner participates in a “Jurassic World” Q&A at the Natural History Museum.

Here at Popular Science, we can’t wait to see Jurassic World, which opens in theaters nationwide today. I mean, who can resist velociraptor biker gangs:

But we were also curious about the real scientific research that inspired the movie. So we talked with Jack Horner, a noted paleontologist who has consulted on the entire Jurassic Park movie franchise, including Jurassic World.

Jurassic Farm: Scientists Are Planning to Resurrect an Extinct Cattle Species

Posted by in category: bioengineering

In Brief

  • The Rewilding Europe project seeks to bring back an extinct cattle species called aurochs which inhabited the wilds of Europe and Asia until 1627.
  • Using back breeding, scientists think in about seven to 10 years we will have a stabilized group of cattle, which will help shape the European landscape.

America’s refusal to embrace gene editing could start the next Cold War

New version of this out:…-cold-war/ #transhumanism #biohacking

Unlike other epic scientific advances…the immediate effect of genetic editing technology is not dangerous. Yet, it stands to be just as divisive to humans as the 70-year proliferation of nuclear weaponry.

The playing field of geopolitics is pretty simple: If China or another country vows to increase its children’s intelligence via genetic editing, and America chooses to remain “au naturel” because they insist that’s how God made them, a conflict species-deep will quickly arise.

Genetic researchers discover ‘stop’ button for CRISPR gene editing tool

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

Researchers have discovered a technique that could block the effects of a powerful gene-editing tool to protect adjacent genes against accidental alteration. The breakthrough could be the beginning of a major step forward for genetic engineering.

Scientists at the University of California (UC) in San Francisco researchers have discovered how to switch off the effects of the CRISPR gene editing system. CRISPR has been a major advance for gene editing, but there are difficulties in limiting its effects on adjacent genes. So far this has militated against its use in research, most obviously, into the human genome.

The Ethics of Synthetic Biology

Posted by in categories: bioengineering, biological, ethics, law

Nice article raising old concerns and debates on ethics. Synbio like any technology or science can in the wrong hands be used to do anything destructive. Placing standards and laws on such technologies truly does get the law abiding researchers, labs and companies aligned and sadly restricted. However, it does not prevent an ISIS, or the black market, or any other criminal with money from trying to meet an intended goal. So, I do caution folks to at least step back assess and think before imposing a bunch of restrictions and laws on a technology that prevents it from helping those in need v. criminals who never follow ethics or the law.

When artists use synthetic biology, are they playing God, or just playing with cool new toys? Scientists Drew Endy and Christina Agapakis weigh in on the ethics.

Model‐guided combinatorial optimization of complex synthetic gene networks

Posted by in categories: bioengineering, biological, genetics

Constructing gene circuits that satisfy quantitative performance criteria has been a long‐standing challenge in synthetic biology. Here, we show a strategy for optimizing a complex three‐gene circuit, a novel proportional miRNA biosensor, using predictive modeling to initiate a search in the phase space of sensor genetic composition. We generate a library of sensor circuits using diverse genetic building blocks in order to access favorable parameter combinations and uncover specific genetic compositions with greatly improved dynamic range. The combination of high‐throughput screening data and the data obtained from detailed mechanistic interrogation of a small number of sensors was used to validate the model. The validated model facilitated further experimentation, including biosensor reprogramming and biosensor integration into larger networks, enabling in principle arbitrary logic with miRNA inputs using normal form circuits. The study reveals how model‐guided generation of genetic diversity followed by screening and model validation can be successfully applied to optimize performance of complex gene networks without extensive prior knowledge.

College Students Show How Easy It Is to Use Terrifying Genetic Engineering Technology

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

The gene drive is quickly becoming one of the most controversial technologies of our time. Its possibilities are at once spectacular and alarming: by using genetic engineering to override natural selection during reproduction, a gene drive could allow scientists to alter the genetic makeup of an entire species. This could be used to eliminate diseases and protect natural habitats —but could also go horribly wrong in the wrong hands.
