Where ants come from?

I am often perplexed with how many ants I have in my house. If someone could dissolve the whole house but the ants; I think you will still see a skeleton of my house made out of ants. Anyway, I love ants – so I have no problem. My family, not so much. So while…

Biodiversity in an old flower vase in my yard

To celebrate biodiversity day, I am sharing a few observations that I made from a mini-zoo in my yard. This is inspired by both laks and manu who regularly create long-term cultures and follow them to observe how life evolves in a mini-ecosystem.  Here’s the old vase that I let fill with rainwater a few…

Foldscope Fun At Moss Landing Beach

Hello foldscopers! I decided to explore the Moss Landing Beach because I work near there every day and have yet to explore the beach up close and personal! Moss Landing, California sits at the head of the Monterey Submarine Canyon, which is over twice the size of the Grand Canyon but underwater!  I took this…

Exploring Tide Pools At Carmel Point

Hey there foldscopers! My marine science class had a lot of fun going to explore the tide pools at Carmel Point in Carmel, California! There was so much cool stuff to see! Carmel Point is a Rocky Intertidal ecosystem residing along an erosional coastline and in the center of Carmel Bay. It was raining on...

Brine shrimp, up close and personal

Brine shrimp, take 2 Our brine shrimp buddies survived the night and I invented a new mounting method so as not to squish them! We also got a better handle on lighting and focus conditions which was very exciting. Here we can see the body of the shrimp pulsating – perhaps the heart working hard!…

Brine shrimp!

Hello (Foldscope) world! I am excited to share my first presentable video with you. I am still working on my focusing technique, but am just so happy that we were able to get the lighting right to see some brine shrimp wiggling around! These cute little guys were collected from the fish room of our…

Moss suspended in water #BIO 60

Hello hello! This time I collected some moss on the ground and trees in a small water bottle and let it sit for about a day. I was hoping to see some tardigrades in it but I wasn’t expecting to. And I did not see tardigrades.   However, I got a couple nice moss pictures…

Snake Skin #Bio60

Snake Skin Film This is a short clip of a piece of shed snake skin that I observed in class. In the clip, I was looking at the boundary between two scales. I was fascinated by the complex structure of the scales, and wanted to know more about how snake scales are formed – why do…

#Bio 60 Ibuprofen Dissolving

Ibuprofen was crumbled onto a glass slide. Water was then added by a dropper, which began to dissolve the medication.

Beauty is in the eye of the Bee(wing)-Holder #Bio60

The phrase “as busy as a honey bee” has never quite been so applicable. On my way to class, I found a dead bee on the side of a busy cross-section on Stanford’s campus. (I admit, I feel a little guilty about the thought crossing my mind first being: “I can look at it with…

Folscope Presentation Wins 1st Place in the Louisiana STEM Expo!!

Our school competed at this year’s Louisiana STEM Expo.  Our presentation of foldscope and its many applications for use got loads of attention!  We were even invited to present to the Louisiana State Board of Elementary & Secondary Education (BESE) to explain how this technology can be used in public & private schools across the…

Bayland Sludge Nematode #BIO60

These videos are of organisms found in sludge water taken from the Baylands near Stanford. The water was teeming with life, including this roundworm. At first, we identified it as a polychaete, a type of annelid worm. However, upon further inspection, we have concluded that it is most likely a nematode. Annelids tend to have larger bodies…

Live Ant exploration in class #bio60

Today in class, I was able to view a twitching ant using the foldscope. With the foldscope, I could clearly see the ant’s eyes and watch its legs and muscles twitch. It was a bit difficult getting the ant onto the slide, so I had to crush it a bit in order to secure it…

Gliding Filament Showing Fragmentation

Hello Everyone, This time I’ve observed this filamentous form which appeared to gliding just like the cyanobacteria we observed in Manu Sir’s post a few days ago. I could see it moving back and forth but not rotating. I haven’t been able to recognize what organism this is. Please help me identify it, I’d love…

Sand and Algae near Monterey Fishermen’s Wharf

I stumbled upon a cool little beach next to Monterey’s Fishermen’s wharf.  It seemed very protected, and was currently inhabited by a few harbor seal, who were laying on rocks just past the shore.  It was low tide, and there were lots of exposed tide pools to the south side of the beach. I took…

Day 7: Lichen culture– part 2

Continuing from my previous post, the April22-plate 3 was really remarkable. Without much ado, here is a sampling of what I saw. Looking forward to your feedback and also can you identify the mystery objects: 1. Nematode (Nematode-24728-1-LI): A fairly large nematode. You can see the pharynx and a bit of the digestive track. There…

Bizarre Tetrahedron diatom from bedwell bayfront park

I drove a fellow lab-mate to collect samples from the bedwell bayfront park. I did some collections myself and observed the most bizarre diatom that I have ever seen. I’m calling it a tetrahedron but not sure if that’s right. If anyone can help id this  beast,that would be much appreciated! I first saw this…

Loch Ness micro-monsters. (Diatoms)

A few weeks ago, Julie F. shared with me another bottle of water sample that her generous friend Kathy had brought. This time the sample was from Loch Ness (Lake Ness) in Scotland. If you recall, this is the same duo who had previously shared samples from the Ganges River in India. Kathy seems to…

Detritus worm in Plant Vase water

Looking for something in the water taken from my plant vase, I came across this Detritus worm! It can be seen moving and even feeding on something. Look closely, you can even see its mouth moving and the digestive track. Can’t wait to look through more water samples and see what I find there!

Day 7: Lichen cultures

Continuing from my previous post, I am going to try and keep an eye on the succession of life in my lichen cultures. For this, I have 6 different lichens collected from different trees put into petridishes containing RO water. Below, I categorize all life I could see after 1 week. Here are results from three…

Kelilalina high school, Ranomafana National Park, Madagascar

With our partners at PIVOT, CVB and Stanford; we had an incredible opportunity to run large scale workshops in schools in Madagascar. We were fortunate that the workshop was documented by an incredible Japanese crew that documented this. I am quickly sharing this video; that allows you to see what it takes to run an…

Life in a Creek Next to a Sidewalk

My worm-san is still alive and well after 20 minutes of scrutiny. This one was very patient with me. Thank you worm-san. You can go safely back to the soil now. This worm-san kept wiggling around in between two pieces of tape (I made sure it’s not too tight). I could quite clearly observe its…
