The National Summer Undergraduate Research Project (NSURP) #nolabnoproblem initiativeProjects & Presentations

September 11, 2020

Greetings, friends!

This summer I’ve spent a lot of time outside, going on hikes and enjoying nature. Pennsylvania has a high rate of lyme disease so I’m always careful to check myself for ticks after I spend time outdoors. With that in mind, I want to highlight the review article included in today’s digest that focuses on the interactions between Borrelia burgdorgei and ticks. If you’re looking for a book recommendation, Bitten: The Secret History of Lyme Disease and Biological Weapons by Kris Newby is an excellent pairing!

The summer is also a time where many undergraduates gain important research experience. For those of you thinking ahead to next year, today’s digest also includes an article which provides 10 simple rules for an inclusive summer coding program for non-computer-science undergrads.

Finally, I am very excited to promote Black in Microbiology week, which will be held on Twitter and Instagram during the week of September 28th. I’m looking forward to “meeting” lots of new microbiologists and learning about their research! Each day has unique programming and hashtags, so check out the website for more information.

Happy reading!

Greetings!

Today’s digest is heavy on environmental microbiology with topics ranging from marine microplastics to carbon budgets to kitchen waste. I want to especially highlight a study that examines the phyllosphere of the mānuka. They found that the mānuka, or tea tree, has a stable core microbiome and variation in the non-core taxa is explained by biogeographical patterns.

Enjoy!

Good morning from Massachusetts! Dr. Elisabeth Bik will be giving a Zoom talk today on research misconduct in biomedical research. You can register at the link under events. Fittingly, today’s digest includes a preprint on the effects of retraction after misconduct on citations. Other highlights today include an entire theme issue on the microbiome and host evolution and a paper on phylogenomic analyses of archaea attempting to elucidate the DPANN lineage. In early life, the placental microbiome debate rages on with a paper demonstrating evidence for contamination rather than an actual placental microbiome. Finally, I have highlighted a paper studying whether soil archives can give us a glimpse into soil microbial communities of the past.

Have a great weekend!

July 15, 2020

There are several notable entries in today’s digest. Registration is open for the European Learning Laboratory for the Life Sciences’ “Introducing Your Microbiome” virtual training course. The course is for European secondary school science teachers and is 5 weeks long. The 3rd Microbiome Movement will also be held this year, both virtually and in-person. Links are in the Events section.  

Today I’ve highlighted a bioinformatics paper on variant calling for cpn60 barcode sequencing and an early life paper on pre-term infant stem cell proliferation upregulated by microbial metabolites. While putting this digest together, I learned algae turns snow different colors! This is so cool to me that I’ve highlighted that paper as well. Finally, the News section includes an article for Smithsonian Magazine by Rob Dunn on quarantine’s effects on our microbial passengers.  

Happy reading!
