The study by Rahim Rahimi and colleagues was published in April and was covered in several news outlets. Purdue University News describes the invention: Purdue University researchers built a way to swallow a tool that acts like a colonoscopy, except that instead of looking at the colon with a camera, the technology takes samples of bacteria. The technology could also move throughout the whole GI tract, not just the colon. This tract, in addition to the colon, includes the mouth, esophagus, stomach, pancreas, liver, gallbladder, small intestine and rectum. Essentially, this tool would make it possible to conduct a “gut-oscopy”. A video showing how it would work is on YouTube.
‘It’s all about being able to take samples of bacteria anywhere in the gut. That was impossible before,’ said Rahim Rahimi, a Purdue assistant professor of materials engineering.

Over the year, our reviewers and Associate Editors have handpicked articles of particular interest and marked them as HOT. We are very pleased to highlight some outstanding 2020 biological chemistry HOT articles:
Molecular crowding induces primer extension by RNA polymerase through base stacking beyond Watson–Crick rules
Shuntaro Takahashi, Naoki Sugimoto et al., DOI: 10.1039/D0RA06502A
In their article Shuntaro Takahashi, Naoki Sugimoto and colleagues investigated the effect of chemical environments on gene replication of the virus RNA polymerase, providing insight into not only the evolution of life but also the mechanism of mutation of the virus genome including SARS-CoV-2.
“The stability of the Watson-Crick base pair is NOT always the most stable, which can be perturbed by molecular environments. Therefore, we speculated that the replication of nucleic acids in the enzyme could also be affected by molecular environments and cause replication errors”, says Professor Sugimoto. “We were excited to find the replication rules became dependent on the stacking interactions more than Watson-Crick base pairing under molecular crowding conditions. This indicates that the replication error can be simply explained by the changes in dielectric constant.”
Their results suggest that the molecular environment could take part in the evolution of life by enhancing the replication error of genome sequences and highlight the significance of molecular environments of patients’ cells for spreading viruses.
