Biodiversity in a small drop of pondwater

Yesterday was Biodiversity day. Biodiversity is usually celebrated with pictures or collages of a wide range of animals and plants. To think that it is only about 1% of life on earth is mind-boggling.  We are so sensitive to extinctions of mammals, birds, insects and plants today thanks to a few remarkable individuals who have…

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…

ராஜாஜி பூங்காவில் மடிப்பு நுண்ணோக்கி

ராஜாஜி பூங்காவில் கடந்த 18ம் தேதி குழந்தைகளுக்கு நுண்ணுயிர் குறித்த விளக்க உரை நிகழ்த்தப்பட்டது. இதில்  மதுரையின்  பல்வேறு பகுதியிலிருந்து சுமார் 168 மாணவர்கள் பங்கேற்றனர். குறிப்பாக அனைவரும் சேரி பகுதியிலிருந்தும், பின் தங்கிய பகுதியிலிருந்தும் வந்திருந்த குழந்தைதகள். அவர்களுக்கு மடிப்பு நுண்ணோக்கியின் பயன்பாடு பற்றி விளக்கம் அளிக்கப்ட்டது. அவர்களுக்கு பூங்காவிலிருந்த பூக்களின் மகரந்தம் மற்றும் இலைகளின் உற்பகுதியை காட்டினோம். குழந்தைகள் உற்சாகம் அடைந்தனர். இதில் மதுரையின் தெற்கு முன்னாள் எம்.எல்.ஏ. திரு நன்மாறன் பங்கேற்றது கூடுதல்…

புளிச்சிக் கீரை

புளிச்சிக் கீரை. விவசாயிகளின் காட்டு உணவு. பொதுவாக இது காடுகளில் வரப்புகளில் வளர்க்கப்படும். இது பயிர்களின் வேளியாகவும் இருக்கும். அதன் உற்பகுதியை மடிப்பு நுண்ணோக்கியில் பார்த்தோம். அற்குள் கறுப்பு நிறத்திலிலும், வெளிரிய சிவப்ப நிறத்திலும் காணப்படுகிறது. இதுதான் அந்த புளிப்புக்கு காரணமாக இருக்குமா? தெரியவில்லை. ஆனால் விவசாயிகளுக்கு காட்டில் உணவு உண்பதற்கு இது ஒரு ஊருகாய் போன்றது.

Exploring at Point Carmel

Hello Foldscope Community, With my Marine Ecology class we’ve been to Point Carmel, which was so beautiful and it got a lot to explore! The intertidal zone is the area where land and sea meet. It is covered in water during high tide and is out of the water when it is low tide. Through…

Microscopic movement

Hello Foldscope Community! Also from the breakwater at Monterey harbor, I’ve been able to document the movement of something that looked like a shrimp. I was totally impressed to see some movement under my foldscope and I wanted to share this with you! There are so many amazing microorganism just at the surface! This foldscope…

Exploring the Monterey Harbor

Hey Foldscope Community! My name is Freya and I am an international student at CSUMB, so I got this awesome opportunity to get to work with a foldscope. These pictures originated from samples I collected with my Marine Ecology class in the Monterey Harbor. We were using a 202 micron net to collect microorganisms from…

Foldscope Fun At Point Lobos

Hey there foldscope friends! I wanted to share my Point Lobos experience with you because there were lots of things to see and explore! Point Lobos is a State Natural Reserve  located in Monterey County, California along the Central California coast. It is absolutely beautiful and people come from all over the world to get a…

ஈ இவற்றின் பாகங்களின் உள்பகுதி

தமிழ்நாடு நீலகிரி மாவட்டத்தில் உள்ள கோத்தகிரியில் நடைபெற்ற ஆசிரியர்களுக்கான பயிற்சி முகாமில் மடிப்பு நுண்ணோக்கி பயிற்சி வழங்கப்பட்டது. இதில் 52 ஆசிரியர்கள் மற்றும் மாணவர்கள் பங்கேற்றனர். மலை கிராமத்தைச் சேர்ந்த மாணவர்களும், அக்கிராமங்களில் பணி செய்கிற ஆசிரியர்களும் பங்கேற்றது மற்றொரு சிறப்பு. மலை கிராமங்களில் உள்ள மாணவர்கள் பெரிதும் பயன்படுத்த முடியும்.  மலை கிராமங்களுக்கு மடிப்பு நுண்ணோக்கியை கொண்டு சேர்க்க வேண்டிய கடமையும் எனக்கு இருப்பதை உணர முடிந்தது. இது வரை இது போன்ற அறிவியல் உபகரணங்களை…

Bio 60 Baylands Sample

The following video is of a sample taken from the baylands of the San Francisco Bay Area. The mixture of sludge, mud, and plant material makes for a really cool pattern close up, especially with the light module installed behind the lens. The sample was prepared by laying two stack of 3 pieces of double…

#BIO60 Sample of Mud from the Baylands Nature Preserve

This is a video I took while examining a sample of mud from the Baylands Nature Preserve. What was most remarkable to me about viewing this sample up close was the color: the mud has a black, tar-like appearance from a distance but, under the Foldscope, it turned out to be various shades of green.

How ticks come for a ride? 

This is a story of an animal that is a master of hitching a free ride on you; even if you like it or don’t. I am talking about ticks. With all the challenges with Lyme disease – it’s something that all of us should take seriously.  On a beach in Northern California – I…

BIO 60 Flatworm/Larvae Observed in Bay Water Sediment

                For my first post I looked at some Bay water microscopic life among filaments of algae. Using the high powered lens I had spotted particularly small single-celled organisms. This time I again looked at Bay water but at the soil sediments from the Bay and not algae in…

Strawberry #Bio60

I decided to look at the inside of a strawberry from the dining hall. I took a small piece of it, smashed it, and put it on the slide. It was difficult to focus the pictures, but on some you could see vein-like structures and bold curves.

Fuzzy Flower Close-up #BIO60

Cool flower ALERT For this foldscope pic, I looked at a close-up for a fuzzy flower that I found on my way to class one day. I’m not really a flower guy, but it was really interesting to have a close-up on the strands that I didn’t quite expect to be there! At first, I…

Fruit Fly #Bio60

I examined a fruit fly given to me by a TA in class. I placed it onto the slide and taped the ends to create a little room before placing a cover slide on top. However, it seems as though the fruit fly was still squished. When viewing the fly, I could see some liquids…

Bayland Sludge Video #BIO60

This is a short clip from my explorations with the bayland sludge liquid sample brought to class by the instructors. This sample, despite its pungent sample, led to some interesting observations with the foldscope. There were some organisms (possibly an amoeba, or a paramecium) that moved rapidly throughout the foldscope screen. The fact that I…

Rhodophyta

There are three divisions of algae, which are red, brown and green seaweeds. Rhodophyta is the latin name for the division red algae. This division contain over 6200 species of algae and 90 % lives in the ocean. Rhodophyta is evolutionary the oldest, and it is now acknowledged that these photosynthetic groups evolved independently of each other. Actually, one…

Red Flower Petal #BIO60

This is from a red flower petal outside my dorm. The cells are very interestingly shaped, clustered together. It looks very different from other flower petals that I’ve observed with my Foldscope.

Tussock Moth #Bio60

These are images from different parts of a Tussock Moth. These moths are seen all around Stanford’s campus during the spring months. It took me around forty minutes to actually catch one of them, and I probably looked ridiculous in my attempts. It was certainly worth it however, as under the Foldscope the wing and…

Macrocystis pyrifera

Macrocystis pyrifera is the common name for the giant kelp, which is the largest of all seaweeds. This species is the major canopy-forming seaweed and it can be up to 55 m (180 ft) in length. When Charles Darwin saw this seaweed in 1834, he was very fascinated by the kelp, and after he first…

Desmarestia ligulata

One gloomy foggy April day in Still Water Cove, Monterey, CA a desmarestia ligulata was found in the drift on the beach. . I am in the class ‘Marine botany’ in Moss Landing Marine Labs, and this day we had our last field trip. This species of brown seaweed is commonly called flattened acid leaf because…

Sludge Life #BIO60

IMG_7476.MOV This was a few minutes of film from our analysis of the dark pond sludge that was brought in to Bio 60 lecture. Though only a few drops were administered, the abundance of material and life were incredible. Peep our skills in tracking paramecium and other critters.

Bio60: Fruit Fly

In class, I was given some sort of fly - most likely a fruit fly - that had stuck to a piece of tape, so I placed it on the slide and analyzed it (dry slide). Unfortunately, the coverslip crushed it a tad bit, but you can still see some features such as the eyes/head...

Bio60: Wasp

I found a wasp that had molten its outer shell or died leaving simply it’s skin, which ever is more likely to happen. I decided to cut part of it up, and examine it. I found that some areas are more dense than others, and even though it looks very lace-like under the foldscope, when…
