Check out this report about researchers at Cincinnati Children's Hospital Medical Center who successfully created stomach fundus tissue in the lab using human pluripotent stem cells. Their research, published in Nature, demonstrated that the tissue was able to produce stomach acid and digestive enzymes, indicating high potential for use as a model system. Imaging was performed using a Nikon A1Rsi resonant-scanning confocal microscope with spectral detector.

Researchers at the UC San Diego and University of Groningen have published an open-access article in PLOS Biology that provides proof for a mechanism of collective resistance in microbial communities via intracellular antibiotic deactivation. Deactivation of the antibiotic chloramphenicol by resistant bacteria dropped the overall concentration in the growth medium to the point that non-resistant bacteria began to proliferate and even outcompete resistant cells. Live cell imaging was performed with a Nikon Ti-E inverted research microscope.

Researchers at Northwestern University Feinberg School of Medicine have demonstrated that the microRNA-103/107 family regulates macropinocytosis and end-stage autophagy in the stem cell-enriched limbal epithelium of the eye. Their research, published in the Journal of Cell Biology, found that loss of microRNA-103/107 results in dysregulation of macropinocytosis and formation of large vacuoles. In collaboration with Josh Rappoport of the Nikon Imaging Center at Northwestern, vacuole morphology was characterized using the Nikon N-SIM super-resolution system.

New open-access research in Scientific Reports details a 3D microwell array system for culturing human tumor cells infected with Kaposi’s sarcoma-associated herpesvirus (KSHV). Cells grown in 3D had higher KSHV genome copy numbers than those grown in 2D control (measured by fluorescence microscopy) and higher rates of lytic reactivation, providing a more physiologically relevant model for infection. Live cell imaging was performed using a Nikon Ti-U inverted fluorescence microscope.

Most of us have probably had an overdue library book, but likely not 122 years overdue. This NPR article covers how the headmaster at Hereford Cathedral School received a package containing a copy of Walter Benjamin Carpenter’s The Microscope and Its Revelations that was originally checked out of the school library in 1894. Fortunately the library does not charge late fees.

Here’s a news article from Science about recent research using stem cell genes to rejuvenate mice exhibiting symptoms of Hutchinson-Guilford Progeria Syndrome – a genetic disorder resulting in signs of premature aging. Activation of just four genes helped ameliorate several symptoms of old age – helping to thicken skin, reduce deterioration of the kidney and spleen, and improve cardiac function.

Nikon Instruments Inc. today unveiled the winners of the sixth annual Nikon Small World in Motion Photomicrography Competition, awarding First Place to William Gilpin of Stanford University for his video depicting an eight-week-old starfish larva churning the water around its body as it searches for food. Gilpin and his colleagues studied the starfish larva as a model system for how physics shapes evolution, and were surprised and intrigued that a common organism like a starfish could create such an intricate and unexpected pattern in the water.

Check out this new article in Nature Microbiology detailing the structure of archaellum using cryo electron microscopy. Archaellum are analogous to bacterial flagella (driving cell motility), but found in Archaea. Researchers at UCLA used CryoEM to image archaellum at 3.4 angstrom resolution, finding significant structural differences compared to flagella.

Researchers have developed fluorescent cell-permeable “super-binding” peptides for specific labeling of gephyrin - a marker of the inhibitory postsynaptic density - demonstrating conventional and super-resolution imaging of inhibitory postsynaptic sites for the first time. These peptides also act as modulators of inhibitory neurotransmission. The authors hope to expand the desigin and use of fluorescent “super-binding” peptides to other cellular targets.

Researchers from UCSF and the University of Illinois at Urbana-Champaign have succeeded in pausing the development of mouse blastocysts for up to one month via inhibition of the mTOR protein. Briefly paused embryos retained the ability to develop normally. This strategy also worked on cultured embryonic stem cells, inducing a pluripotent state that can last for weeks in vivo. Their research has implications in a variety of fields, including ageing, cancer, assisted reproduction, and more.
