Scissors get stuck—another way bacteria use CRISPR/Cas9

Posted by in categories: bioengineering, biotech/medical

In biotech these days, CRISPR/Cas9 is a hot topic, because of its utility as a precise gene editing tool. Before humans repurposed it, CRISPR/Cas9 was a sort of internal immune system bacteria use to defend themselves against phages, or viruses that infect bacteria, by slicing up the phages’ DNA.

Scientists at Emory University School of Medicine and the Max Planck Unit for the Science of Pathogens have found that the “scissors” component of CRISPR/Cas9 sometimes gets stuck.

Cas9, an enzyme that cuts DNA, can also block without doing any cutting. In the pathogenic bacterium Francisella novicida, Cas9 regulates that need to be shut off for the bacteria to cause disease.

How a healthy microbiome could supercharge the body’s natural cancer-fighting cells

Posted by in categories: biotech/medical, health

The ways in which the communities of bacteria living within our bodies influence our overall well-being are becoming better understood all the time, and with that better understanding comes potential new ways to intervene for better health outcomes. Adding to this is a new discovery by researchers in Melbourne, who have described how a healthy microbiome can boost the activity of killer immune cells that are vital to fighting off infections and cancer.

Three ways robots can save lives in war

Posted by in categories: futurism, robotics/AI

Robots like the Pointman Tactical Robot and the iRobot Negotiator are already capable of entering buildings, climbing stairs and moving over obstacles to search buildings. Future versions are more likely to be armed, have more advanced sensors, hold greater autonomy, and be classified.

More agile humanoid (or animal-like) versions of these robots could be used to clear buildings of booby traps and enemy fighters seeking to ambush troops.
