What is this critter in the neighborhood urban creek?

Hello Foldscopers! It is cold outside where I am, but if it is a nice sunny day, I like to go for a walk and explore the creeks in my neighborhood. I love creeks. There is something about following the movement of water that calms me down. But if you live in an urban area…

Prepare a saturated solution of NaCl I.e adding NaCl to water till it stops dissolving. 2. Put a drop of this…

Butterfly scales through the lens of a Foldscope

I was really excited to receive a new Foldscope kit recently, and after corresponding with Manu online, we agreed that butterfly scales represent a nice project that others can easily get involved with! Here are some previous posts on the subject: https://microcosmos.foldscope.com/?p=10080, & https://microcosmos.foldscope.com/?p=16562 Here’s magnification of a butterfly eyespot and through the lens of a #Foldscope below,…

Interesting creature in the neighborhood stream

Sampled moss from a neighborhood stream in Dublin, CA, and found this interesting fellow. No idea what it could be but it looks like it holds to something with its back while it opens its mouth wide and eats (at least that is my interpretation of what is going on). Any idea on what creature…

Some pond creatures, large and small

I collected some water from an artificial pond in the campus. Despite finding itself in the middle of an urban area, in springtime you can hear frogs calling all around. Now it’s winter and the pond is silent, full of rotting leaves fallen from the trees surrounding it. I went there looking for a pond…

Life in a drop o water; secret handshakes

I love the secret handshakes every organism in this video has for one another. They all react when interacting to other organisms – but quiet differently. In the past we have discussed on toxins presented on the surface; but I had not appreciated the diversity of “reactions” a single felled organism would have when seeing…

Watching swimming bacteria in our spit

After a lovely Christmas dinner, my 6-year old nephew (H) and I settle down with a foldscope. And off course we decide to look at spit; in search of bacteria. This is video with the regular basic foldscope without light module. We use just the hanging light in the room as our light source. Enjoy!!…

Symsagittifera roscoffensis

I have the chance to live by the sea in the north west of France, in Brittany. Here, it’s quite easy to sample Symsagittifera roscoffensis directly on the beach during the low tide. They basically look like this under the foldscope : These free-living acoelomorph worms, formerly called Convoluta roscoffensis, have a characteristical green color…

Carbon dioxide sinks

  Yesterday,  whilst I was strolling in my city , I found some spiderwort species growing vigorously nearby and instantly This is what I saw:  epidermal cells and beautiful stomata amongst them. To my surprise, some (four?) subsidiary cells sorround the two guard cells that  make an stomata, a fact I did not know before…

Exploring the sea…at the dining table

Hi there Foldscopers, Hello from Japan! Manu asked me to explore planktons while I’m in Japan visiting family, and I even made my own plankton net a few weekends ago (more on this another day). But I’m finding that the ocean is not as accessible as I had imagined. Why? It’s because the coastline is…

Mites that spin silk; a tutorial for using micro-well slides

Here is a quick example of how to use micro-well glass slides in your kits to trap and keep alive organisms. Spider mites hiding on my #croton plant. They are really small; smaller than a dot in a sentence. Count the legs – and you know they are arachnids. But I did not know that…

Foldscoping on a sailboat – adventures in Yvinec

Thrilled to have a chance to #Foldscope with adventurer Guirec Soudée on Yvinec (boat). Momo (chicken) was not on the boat that day; since some repairs were planned – but we all got to share our love for science and the ocean. In the new year, let’s promise to protect this incredible ecosystem we call…

Glowing hemolymph in an insect

I made a really puzzling observation today. I found a very small flying insect (~1mm) at a friends house. I could not identify if it was a really small fly, wasp or something else. Intrigued; I ended up putting it inside a foldscope. As luck would have it; I squashed the big and a whole…

Ant in foldscope.

First exploration! Its an ant.  Could anyone help me identify those canals in the photos? 🙂

What are these specks on my hot pepper plant leaves?

A colleague noticed whitish specks on the leaves of a pepper plant growing on my window ledge. After examining them with the foldscope (in situ, without a slide), they appear as droplets. But of what? Any ideas? To help give context, here are three different views of what we observed. -Paul Stinson   PS We…
