There were so many Ctenophore larvae in this week’s plankton sample! Ctenophores aka comb jellies are gelatinous animals that use ctenes (combs) to move about, and some have sticky tentacles to capture prey.

Many sea stars begin life as young fairy-like creature (called a brachiolaria) that float through the open ocean. Eventually, a small star forms within them (here in yellow). The fairy-like brachiolaria sinks under the star’s weight, and the star pops out!

In celebration of World Octopus Day, we wanted to revisit one of our favorite cephalopod sightings, the glass octopus — Vitreledonella richardi filmed during a month-long #PhoenixIslandsCoral expedition in 2021.

It's #WorldOctopusDay! These beauties from our collection are both by French pharmacist and naturalist Jean Baptiste Vérany (1800-65).

Octopus vulgaris - the common octopus, which can grow to 9kg and change colour to match its surroundings.
Common octopus with brown and yellow colouring with hints of blue. It has yellow eyes and fills the image.

McGill Physics researchers have developed a new device that can trap and study DNA molecules without touching or damaging them. The device offers scientists unprecedented control over how DNA behaves in real time, creating the opportunity for faster, more precise molecular analysis. mcgill.ca/x/iRJ

It’s Ctenophore Day! (‘Cos it’s the 4th of Oct and in the States you’d say it’s 10/04 ten-oh-four ctenophore. See? See?) So here’s a Ctenophore juvenile for #ctenophoreday ! Now the word ctenophore doesn’t make any sense to me, I’ve said it too many times.

Happy Ctenophore day! Its a perfect day to celebrate such a small yet beautifully diverse phyla that comes in a wide array of shapes and colors. #Ctenophoreday

🌱 Using ‘compelling’ methods, including #CryoET, researchers mapped spinach thylakoid membranes at single-molecule precision, revealing how photosynthetic complexes are organised and settling long-standing debates on chloroplast architecture.

New paper from our lab: The use of #microplastics as case-building material by larval caddisflies facilitates the transfer of plastic (& potentially its associated contaminants) to predatory fish.
Larval caddisflies (Limnephilidae) that had been exposed to microplastics (PET) and natural materials will readily incorporate plastic into their cases. Plastic in gastrointestinal tract of a freshwater fish (brown bullhead) exposed to larval caddisflies whose cases incorporate plastic.

For this #FluorescenceFriday, a gorgeous image of an adult mouse kidney labeled with AQP2 and alpha SMA antibodies. AQP2 (green) marks the collecting duct and distal connecting segment while SMA marks the arterial tree. Courtesy of talented postdoc Sarah McLarnon.
Image of a fluorescently labeled adult mouse kidney showing AQP2 staining of collecting ducts and connecting segment in green and alpha SMA staining of the arterial tree in magenta. The collecting ducts look like squiggly branches.
