Our paper in #cephalopods #cuttlefish is out! With beautiful- interesting results
Holly L. Lutz@fieldomics14 May 2019
Check out our latest work on #cephalopods - Cuttlefish #FISH and a simple #microbiome. A new experimental system perhaps? @microtabi @gilbertjacka @NeilGottel @camouGuy @MBLScience @CMIdigest @microbiomecntr msystems.asm.org/content/4/4…

Have you ever tried hybridizing a biofilm with no success? Our new paper provides a universal solution for visualizing all bacteria in polymicrobial communities by physically slicing through the cell wall barrier before FISH. 🔬✨ Check it out!

#MicrobiologyMonday: Seeing all bacteria in a biofilm is tough—G+ cells walls block probes, and fixes harm G- cells. A new method slices bacteria embedded in plastic resin, letting probes in without damage for clear visualization. #JournalSpectrum: asm.social/2JF
Sectioning enables visualization of complex bacterial communities. Five-micron-thick sections of tongue dorsum biofilm hybridized with probes targeting the problematic Gram-positive bacteria Actinomyces, Schaalia, and Streptococcus, along with six other abundant taxa. Actinomyces and Schaalia are detected as individual branching rods with a strong signal, while Streptococcus cocci exhibit a strong and homogeneous signal. Clusters of intermixed taxa with distinct signals are also observed. Right panels: high magnification images of the dotted squares in the left panel.

Why do bacteria live in specific parts of the mouth? Forsyth scientists have been working to answer this question. @julian_tom and the @JMarkWelch / Gary Borisy labs recently published a paper that adds to our understanding. Read the full article here ow.ly/z4U350OZKia

I am thrilled to share with you my recently published work showcasing the distribution of Gemella species in the oral cavity using metapangenomics. This accomplishment was made possible by the extraordinary team at @Forsyth. Congratulations! tandfonline.com/doi/full/10.… – at Cambridge, MA

Site-specialization of human oral Gemella species

Gemella species are core members of the human oral microbiome in healthy subjects and are regarded as commensals, although they can cause opportunistic infections.Our objective was to evaluate the ...

You can't leave out microbes when talking about the tongue! @ScienceMagazine's deep dive covered it all and featured some Forsyth imaging. Scroll to the bottom of the article to see @JMarkWelch's explanation of microbial communities on the tongue. science.org/content/article/…

How the tongue shaped life on Earth

By specializing for catching, ingesting, and swallowing all sorts of food, tongues had dramatic impact on animal evolution

At a recent conference, most talks ended with an ad for postdocs. Unchanged @NIH modular budgets, low postdoc salaries, visa complications, uncertain career prospects, are problems. Yet the U.S. research model depends on postdocs. Something has to change. nature.com/articles/d41586-0…

Lab leaders wrestle with paucity of postdocs

Nature - Even high-profile scientists are struggling to recruit qualified postdoctoral researchers.

#MicroscopyMonday🔬| Kelp forests can tower up to 150 feet high, but like many living things, kelp survival depends on microorganisms associated with its surface. This image of kelp blade shows microbial biofilm on both sides of the blade. Credit: Ramírez-Puebla et al.(2022)
