The US Military Is Genetically Engineering New Life Forms To Detect Enemy Subs

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

The Pentagon is also looking at living camouflage, self-healing paint, and a variety of other applications of engineered organisms, but the basic science remains a challenge.

How do you detect submarines in an expanse as large as the ocean? The U.S. military hopes that common marine microorganisms might be genetically engineered into living tripwires to signal the passage of enemy subs, underwater vessels, or even divers.

It’s one of many potential military applications for so-called engineered organisms, a field that promises living camouflage that reacts to its surroundings to better avoid detection, new drugs and medicines to help deployed forces survive in harsh conditions, and more. But the research is in its very early stages, military officials said.

CRISPR has many promising applications—but the gene-edited twins represent something more troubling

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

Last week Chinese researchers rocked the world with reports that twin babies whose genes the scientists’ edited prior to birth had been born, the product of secret experiments that are being widely decried as unethical. Even as that story plays out, it is true that CRISPR gene editing is already being used in humans, in ways that illustrate just how unethical this recent use was.

“Patients’ parents have been emailing me a lot,” says Hye Young Lee, a researcher at the University of Texas San Antonio whose work looks at alternative delivery methods for CRISPR. Lee says she normally gets a few emails a month from the parents of the patients she works with, but that the number of emails went up recently—in relation, she suspects, to the news of the CRISPR babies, which is creating the illusion that CRISPR and other gene editing techniques are ready for extensive use in humans.

The scientific community’s current consensus is that they’re far from being at that stage—and it’s impossible to know now when or if they will be. But gene editing is being used in adult humans, to early trials to treat genetic diseases. In terms of gene editing for adults, “I know that there are things going on,” Lee says, but it’s nothing like this week’s news. Although her own work is at least a few years away from being ready for human testing, there are some cautiously progressing trials at drug companies using CRISPR in adult humans who have diseases that are the result on mutations in a single gene.

Precision genome engineering

Biotechnology
Genome editing through CRISPR-Cas systems has the potential to correct genetic mutations that occur in diseased cells, such as cancer cells. However, the ability to selectively activate CRISPR-Cas systems in diseased cells is important to ensure that gene editing only occurs where it is wanted. Zhu et al. developed a system whereby gene editing could be activated by a magnetic field, thus allowing spatial control. The use of nanomagnets in their system also improved transduction into target cells in tumor-bearing mouse models. This approach could potentially allow the translation of CRISPR-Cas systems into therapeutic agents.

New research could fine-tune the gene scissors CRISPR

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

The introduction of the gene editing tool CRISPR in 2007 was a revolution in medical science and cell biology. But even though the potential is great, the launch of CRISPR has been followed by debate about ethical issues and the technology’s degree of accuracy and side effects.

However, in a new study published in Cell, from the Novo Nordisk Foundation Center for Protein Research have described how Cas12a, one of the CRISPR technologies, works at the molecular level. This makes it possible to fine-tune the gene-editing process to achieve specific desired effects.

“If we compare CRISPR to a car engine, what we have done is make a complete 3D map of the engine and thus gained an understanding of how it works. This knowledge will enable us to fine-tune the CRISPR engine and make it work in various ways—as a Formula 1 racer as well as an off-road truck,” says Professor Guillermo Montoya from the Novo Nordisk Foundation Center for Protein Research.

Syfy’s Nightflyers asks whether humanity deserves to be saved

Posted by in categories: bioengineering, genetics, neuroscience, space travel

Showrunner Jeff Buhler has built a fascinating world around Martin’s story seeds, starting by setting the action within the foreseeable future, rather than in an incomprehensibly distant one. The invented technologies here are particularly intriguing, like the genetic modifications first officer Melantha Jhirl (Jodie Turner-Smith) has to make her better suited for space travel, or the cybernetics technician Lommie (Maya Eshet) uses to interface with machinery. Given the state of real-world technological developments in genetic engineering and research into brain-machine interfaces, the series feels plausible and grounded, even though it’s set in a spacefaring future.


The 10-episode space series adapts a 40-year-old George R.R. Martin novella.

Would I Want a Designer Baby?

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

A couple of days ago, news about the first designer babies has shaken the world. A Chinese researcher, Jiankui He, and his team at the Southern University of Science and Technology of China have been recruiting couples in order to create the world’s first babies with artificially increased resilience to HIV. The embryos were modified using the CRISPR/Cas9 gene editing tool before being implanted in their mother.

According to the research lead, the twins were born healthy a few weeks ago, and genetic testing performed after they were born confirmed that the editing had actually taken place. While the academic community discusses whether it is acceptable or not to modify human genes, taking into account that the changes made will be inherited by these babies’ offspring and are now added to mankind’s genetic pool, I want to share my own views on designer babies.
