In case you missed it (ICYMI), here are some of the stories that made headlines in the world of cleanrooms and nanotechnology in the past week.

A team at Harvard’s Wyss Institute for Biologically Inspired Engineering has, for the first time, been able to tell apart features distanced only 5 nanometers from each other in a densely packed, single molecular structure and to achieve the so far highest resolution in optical microscopy. Reported on July 4 in a study in Nature Nanotechnology, the technology, also called "discrete molecular imaging" (DMI), enhances the team’s DNA nanotechnology-powered super-resolution microscopy platform with an integrated set of new imaging methods. The Wyss Institute’s scientists have benchmarked the ultra-high resolution of DMI using synthetic DNA nanostructures. Next, the researchers plan to apply the technology to actual biological complexes such as the protein complex that duplicates DNA in dividing cells or cell surface receptors binding their ligands.

The BBC has reported that British universities are feeling the effects of the recent Brexit referendum, with European academic bodies pulling back from research collaboration with U.K. academics. Academics based in the U.K. are being asked to withdraw their applications for future funding by European partners. The BBC cited concerns raised by academics at Bristol, Oxford, Cambridge, Exeter and Durham. Several vice-chancellors told the BBC that researchers in European countries are wary of partnering with the U.K. because they don't have confidence in the future, and they also say that they’ve received calls from prospective future EU students about their access to student loans and their immigration status.

A 3D paper-based MFC system is developed to produce current. The device allows flow of the streams of Shewanella Oneidensis MR-1 (yellow) and the Potassium Ferricyanide (white) into the chambers. Proton exchange membrane is placed between the two chambers to separate the two liquids as well as allow the positively charged ions released in the biocatalytic breakdown of the anolyte to flow from the anode to the cathode.

Finally, a team of researchers from Iowa State University has demonstrated a proof-of-concept three-dimensional paper-based microbial fuel cell (MFC) that could take advantage of capillary action to guide the liquids through the MFC system and to eliminate the need for external power. Their report appears in the forthcoming issue of the journal TECHNOLOGY. The paper-based MFC runs for five days and shows the production of current as a result of biofilm formation on anode. The system produces 1.3 µW of power and 52.25 µA of current yielding a power density of approximately 25 W/m3 for this experiment. These results show that the paper-based microbial fuel cells can create power in an environmentally friendly mode without the use of any outside power.
