When microbiologist Emmanuelle Charpentier and RNA expert and biochemist Jennifer Doudna met at a conference in 2011, their shared passion for science led to a profound discovery; a new technique to engineer genomes known as CRISPR-Cas9. The technological and economic revolution that ensued still reverberates through labs around the world. CRISPR-Cas9 has created a seismic shift in how science operates making genome editing fast, flexible, inexpensive and easily accessible to anyone with a modicum of lab equipment. But is CRISPR-Cas9 a bio-hacker revolution or a potential scientific nightmare? Based on a bacterial CRISPR-associated protein-9 nuclease (Cas9) from Streptococcus pyogenes, CRISPR-CAS9 allows researchers to edit parts of a genome, using the same adaptive immune system mechanism bacteria use to recognize viral DNA and trigger its destruction. The CRISPR-CAS9 kit allows sections of DNA sequences to be snipped out and replaced, giving scientists the ability to essentially mutate the DNA. Further complicating the issue are synthetic elements which can now be added to … [Read more...] about Designer DNA: Will CRISPR-Cas 9 Create a BioHacker Revolution or a Nightmare?
Boston Dynamics Terrifying and Astounding Handle Robot
One day in the future, when an engineer discovers a robot has become self aware, there is a good chance that technician will be working at Boston Dynamics. The robotics and engineering company works with various government agencies such as DARPA, the US Army, Navy and Marine Corps, and corporations like Sony. Using sensor-based controls and computation, Boston Dynamics's experimental robots mimic the capabilities of complex organisms, exhibiting remarkable agility, dexterity and speed. If you are a robot watcher like I am, Boston Dynamics's creations are startling in their ability to conjure both utopian possibilities and surreal nightmares. Robots like these could have powerful applications navigating hostile terrains like Mars, or become mindless weapons of war. Boston Dynamics' latest creation is Handle, a research robot with 10 actuated joints which resembles a bucking horse. Handle stands 6.5 ft tall with the ability to retract and extend its legs. The robot has uncanny balance, travels at 9 mph and is able to jump 4 feet vertically into the air, and lift 100 pounds. … [Read more...] about Boston Dynamics Terrifying and Astounding Handle Robot
