Researchers are engineering microbes to deliver therapeutics specifically to tumors, maximizing the treatments’ efficacy while minimizing side effects.

Autonomous, living microrobots that seek and destroy cancer are not as futuristic as one might imagine, thanks to a fusion of robotics and synthetic biology.

Inhaling combustion-produced particles may lead to the development of brain tumors.

DNA-coated gold nanorods enable cells to be activated by light without genetic manipulation.

DNA-loaded nanoparticles that respond to infrared light provide an alternative way to control cell behavior.

Researchers injected the retinas of mice with nanoparticles that bound to photoreceptors and converted near-infrared light to green light that the animals could see.

Small RNA-containing particles in ginger root are found to promote the growth of beneficial bacteria and alleviate colitis in mouse guts.

Small microRNA-containing particles found in the plant can boost populations of healthy gut bacteria, and even improve colitis symptoms in mice.

Whether it’s aligning software or prepping samples, researchers share their tips for studying the metabolome with this underused approach.
