Three scientists in semi-fpormal wear stand in a lab space. One of them cuts a ribbon with big scissors in front of a new microscope that says "DALISPIM" on it. There is a large "GRAND OPENING" banner hanging in the front of the picture, and colorful balloons everywhere.

Four scientists stand in casual wear in a lab space, smiling, around a microscope with "DALISPIM" written on the front. One of them stands behind the microscope comically pointing at it dramatically.

Happy #MicroscopyMonday! Our Head of Innovation Hsuan Lee shared these photos from Peter Sorger's lab (@harvardlab.bsky.social), where we just installed our first #DALISPIM open-top light sheet microscope. Stay tuned for another exciting announcement later this week!

A fluorescence image showing two curved, kidney-shaped plant guard cells forming a stomatal pore. The cells glow in bright magenta, outlining their overall shape, while clusters of distinct round and irregular structures inside them fluoresce green and yellow. The background is completely black.

I pulled this image from the archives of my PhD work, back when I was working with plant and yeast mitochondria.
These are two Arabidopsis guard cells, with their cytosol in magenta, mitochondria in yellow, and chlorophyll autofluorescence in green.

An early stage Kalanchoe foliar embryo. Blue: DAPI; green dots: STM mRNA; red dots: WOX11 mRNA.

#MicroscopyMonday An early stage Kalanchoe foliar embryo. Blue: DAPI; green dots: STM mRNA; red dots: WOX11 mRNA. STM mRNA appears throughout the embryo, but WOX11 appears in the junction between the embryo and the mother plant.

This polychromatic polarizing microscope image of 0.3µ thick calcite film shows real colors, as it is seen by naked eye. The vibrant colors are produced as the calcite crystals form, revealing their molecular orientation.

Cyanobacteria isolated from desert "microbiotic" crust soil. @zcardon.bsky.social's group is exploring how these tiny green algae and cyanobacteria can completely dry out in deserts and then opportunistically pop back to activity when a raindrop hits.

A blob of white signal staining the nuclei of kalanchoe foliar embryo

Close up of the foliar embryo with mRNA detected by fluorescence in situ hybridization. Green and red signals can be seen at the base of the embryo.

#MicroscopyMonday A kalanchoe foliar embryo emerging (white signal staining for DNA). STM (green signal) and WUS (red signal) mRNA can be detected at the basal region of the embryo. WUS has a more narrow expression domain.

Happy #MicroscopyMonday everyone! 🔬🤩
Today’s image comes from Lillian and it’s her first immuno!🐁🧪
In the image, red ❤️ highlights myo7a, which shows the hair cell bodies! Beautiful!

Fluorescence microscopy image of a spherical cluster of chloroplasts, showing magenta-stained interiors surrounded by bright green outlines against a black background.

Moss (Physcomitrium patens) protoplasts (wallless cells) transformed with chloroplast envelope protein tagged with mGFP (green). The chlorophyll autofluorescence is in magenta.
The protrusions of the chloroplast envelope are called stromules.

Fun fact: most of the sophisticated live/super-resolution correlative microscopy we do rests on a (less buggy now) ImageJ macro that transforms stage positions between two microscopes #MicroscopyMonday

Happy #MicroscopyMonday!

Here we have Dermacentor variabilis, aka the American dog tick, showing its distinct markings.

These #ticks carry diseases such as Rocky Mountain Spotted Fever or tick paralysis, and, less typically, #Lyme disease.

Fortunately, they tend to be larger and easier to spot.

This beautiful #MicroscopyMonday shows how maternal regulation governs early embryonic development by coordinating gene expression in both time and space to direct proper embryonic growth. 🔬 @gopalkushawah.bsky.social (@bazzinilab.bsky.social)
