Releasable SNAP-tag Probes for Studying Endocytosis and Recycling Site-specific labeling of cellular proteins with chemical probes is a powerful tool for live cell imaging of biological processes. One popular system, known as the SNAP-tag, is based on an engineered ...

How about a SNAP or tetracysteine tag? pubs.acs.org/doi/10.1021/...

It was a pleasure working with you and Martin!

Virus-like proteins help our cells respond to environmental stress

Endogenous retrovirus-like proteins recruit UBQLN2 to stress granules and shape their functional biology Virus-like proteins help our cells respond to environmental stress.

Our paper discovering novel roles for the retrovirus-like proteins RTL8 and PEG10 in shaping stress granule biology is now online on Science Advances! #llps #stressgranules

Thank you, Chelsey!

Thank you and no worries, Mara!

Earlier this month, I defended my PhD in front of friends and family. As a teenager, I dreamed of this moment and I’m glad it finally came true. Thanks to my mentors, Drs. Paulson and Sharkey and my committee members! I will be starting a postdoctoral position in Dr. Roy Parker’s lab at CU Boulder.

Title: SOME GRAMMATICAL VOICES FOR USE IN SCIENTIFIC WRITING ACTIVE VOICE e.g. Our team collected samples and then we tested them. CLICKBAIT VOICE e.g. We collected some samples... You won't believe what happened next! PASSIVE VOICE e.g. Samples were collected and tested. HAIKU VOICE e.g. Quiet science lab. Workers arrive with samples. The testing begins. PASSIVE-AGGRESSIVE VOICE e.g. We did all the collecting and testing. No need to thank us. Just doing our job. CONSPIRACY VOICE e.g. Mysterious "Samples" were harvested and covertly "tested" by so-called scientists.

Reprogramming site-specific retrotransposon activity to new DNA sites - Nature A study of retrotransposon activity repurposes a retroelement called R2Tocc to create a programmable system called STITCHR that enables diverse genome edits including efficient, scarless large pa...

So excited to share our new paper out today in @nature.com. We repurposed R2 retrotransposons to create STITCHR, a tool that can make virtually any kind of edit in mammalian genomes including the scarless multi-kilobase scale insertions 🧵

Contrary to popular belief, what is important in science is as much its spirit as its product: it is as much the openmindedness, the primacy of criticism, the submission to the unforeseen, however upsetting, as the result, however new that may be. – Francois Jacob

Drosophila follicle showing retrotransposons (pink & yellow) expressed in somatic cells infecting the oocyte

1/ Transposable elements are often called "jumping genes" because they mobilize within genomes. 🧬
But did you know they can also jump 𝘣𝘦𝘵𝘸𝘦𝘦𝘯 cells? 🤯
Our new study reveals how retrotransposons invade the germline directly from somatic cells.

This is so cool. Do you think it would work to segment and quantify 3D STED images?

Estimated Single Year Loss of NIH Funding if 15% Indirect Cost Rate is Imposed Based on analysis of 2024 NIH funding data. Sums are totals of losses in funding to programs if indirect costs had been capped at 15%

Helpful table to determine how much your University or health system is set to lose if the NIH indirect cap is suddenly lowered to 15%. For SJSU it is $374k which is on the smaller end but devastating considering our other budget issues. datawrapper.dwcdn.net/l0ZqA/8/
