People who owned black-and-white television sets until the 1980s didn’t know what they were missing until they got a color TV. A similar switch could happen in the world of genomics as researchers at the Berlin Institute of Medical Systems Biology of the Max Delbrück Center (MDC-BIMSB) have developed a technique called Genome Architecture Mapping (“GAM”) to peer into the genome and see it in glorious technicolor. GAM reveals information about the genome’s spatial architecture that is invisible to scientists using solely Hi-C, a workhorse tool developed in 2009 to study DNA interactions, reports a new study in Nature Methods by the Pombo lab.

With a black-and-white TV, you can see the shapes but everything looks grey. But if you have a color TV and look at flowers, you realize that they are red, yellow and white and we were unaware of it. Similarly, there’s also information in the way the genome is folded in three-dimensions that we have not been aware of.

Scientists have developed a pill-shaped, swallowable camera that can be controlled by physicians once ingested to help doctors diagnose digestive issues.

Ingestible pill-shaped endoscopes are not a new idea. Last year, PetaPixel reported on the Pillcam which is just such a device, but it had limitations just like all other swallowable pill cameras: doctors can’t control it once it is ingested.

Traditional pill cameras are driven only by gravity and the natural movement of a subject’s body, which limits what doctors can actually see. That is poised to change as scientists from George Washington University have developed a first-of-its-kind system that allows physicians to remotely “drive” a pill capsule through all the regions of the stomach to see and photograph potential problem areas.
