Trichomes from a peppermint plant #BIO60

What we see here is the edge of a leaf from a peppermint plant that I am growing in my room. We can see trichomes sprouting from the edges and we can also see what looks like individual cells. Notice how the cells get smaller as we move closer to the edge. Indeed, this leaf is…

#BIO60 Post 1: Hand Callus

#BIO60: Anonymous Person’s Callus from their Palm A person that wanted to be kept anonymous was playing with a callus on their palm while in my dorm room. The callus was eventually torn off, and they volunteered to put it on a slide for me. The callus was not recently washed and therefore still had…

வண்ணத்துப் பூச்சியின் இறகு

   இறந்து போன வண்ணத்துப் பூச்சியை இனியன் தன்னுடைய ஜியாமெண்டரி பாக்ஸ்லிருந்து எடுத்து வந்திருந்தான். அதன் இறகை தொட்டதும் கைகளில் பவுடர் போல ஒட்டிக்கொண்டது.  வண்ணத்துப் பூச்சியின் இறகு. அதனை தொட்டதும் கையில் ஒட்டிக்கொள்ளும் பவுடர் போன்ற பகுதியை எடுத்து Foldscope ல் வைத்து பதிவு செய்யப்பட்டது. அற்புதமான பதிவு. அது மீன் செதில்கள் போல காணப்பட்டது. வெளியில் பார்க்கும் போது பச்சை மற்றும் கறுப்பு வண்ணத்தில் இருந்தது. உள்ளே பார்த்தபோது அதற்கான அறிகுறியே தெரியவில்லை. வேறு…

#BIO60 – Leaf and Flower

I started my adventure with the foldscope by looking at a green leaf. I observed the patterns and even got to see a couple of individual cells near the corners of the leafs. Unfortunately, because the leaf was too dark I could not capture very clear images, and the media I posted mostly is composed…

Sample of Unknown Microbe Taken Off Hand #BIO60

This is a photo of a colony of some unknown microbe. The sample shown in this photo was obtained from a culture of microbes found on my right hand. The culture was performed by swabbing my hand for ten seconds with a cotton swab that was then swabbed on an agar plate. The plate was…

Moss #Bio60

Here are some photos of moss I found growing next to a bush. The sample I used also contained tiny pieces of dirt that would not separate from the moss. I placed a few drops of water on the slide to help the moss flatten and stick to the slide. It is interesting to see…

Caterpillar Hair #Bio60

This is an image of caterpillar hairs I found on a leaf outside of my dorm. I took the hairs off of the leaf and placed it onto a glass slide with the ends of the slide taped. Next, I added a few drops of water and taped a cover slip on top to keep the…

Feather #Bio60

So I discovered a little too late that my pillow actually is down-stuffed, and decided to look at one of the feathers under the Foldscope. There’s a lot of detail here; you can see individual fibers from the microscope, which I thought was great. The light from my laptop made it easier for me to…

Flower Petal #Bio60

Image of a flower I found walking near Green Library. In the image you can see a piece of the petal along with a defined vein running through it, as well as a piece of the green stem that it is connected to.

Grass Eaten by Sick Mouse #BIO60

Near Lake Lagunita at Stanford University, there was a small, brown field mouse near the edge of the path. Upon moving closer, the mouse seemed to not have any visible fear of me. It carried on as normal, eating the ends of the grasses nearby, but there were black flies settling onto its back and…

Bush Leaf #BIO60

This is an image of a a small piece of a leaf that I obtained off a bush outside the STLC a few weeks back and prepared onto a slide in class. The piece was ripped off, and put onto a glass slide with a drop of water put with a pipette. Then the cover…

Dead Skin #BIO60

This is a picture of dead skin. Using my iPhone light, i was able to photograph the skin with only slight difficulty. I chose the best of several pictures I took at different areas of the sample. I found the dark ridges and lines in the skin very interesting. The skin is effectively translucent which…

Plant Stem Cross-Section

   Using a razor blade, I cut a thin, transparent perpendicular cross-section of a stem I found outside the courtyard of my dorm.  You can see the individual cells pretty clearly in the image. I’m also not sure what the green circles in the second frame are, but am curious as to what purpose they serve.

Calanus copepodite?

I selected a small copepod to try out my first real attempt at a dry mount, again using a glass slide and cover slip. I was unable to get my phone to focus on something this small, but here you can see that the copepod is about 2mm long. I tried not to crush my…

Wet-mount preparation of red alga from Monterey Bay

I love to I.D. algae in the intertidal, but red algae can be especially cryptic.  Here I am preparing my sample with a glass slide, and a glass slip that I am holding together with some Scotch tape so that I can wiggle it into place within my foldscope. The water in my wet mount…

Adventures in Oregon #BIO60

As a member of the Stanford softball team, I had the unique opportunity to explore the outdoors while playing a three game series against Oregon State in Corvallis. In my downtime, the Foldscope was pulled out to better observe nature. My teammates were very curious with this device and ended up being consumed by it….

Flower Petal #BIO60

These photographs came from a flower petal taken from a fresh flower. The petal had a gradient of colors, which was clear under the foldscope. The more “zoomed out” photos show the individual cells on the petal, which also carry the color pigment evident in the multicolored flower. I had trouble focusing my phone camera…

இட்லி மாவின் மேல் படர்ந்த பூஞ்சை

இது இட்லி மாவின் மீது படர்ந்திருந்த பூஞ்சையின் பதிவு. போல்ட்டு ஸ்கோப்பில் வைத்துப் பதிவு செய்தது. அவைகள் நூல் போன்று இருப்பதை பார்க்க முடிகிறது. தண்ணீரை கயிறு திரித்தது போல அற்புதமாக தெரிந்தது. இது முதின்ஸ் குழுவினரின் பதிவு.

Spider Web #Bio60

This photo was taken of the thicker portion of the spider web. When I was transferring the web onto my slide the web bunched up a bit and caused this bundle to appear. This photo was taken of a single strand of the spider web.

Leg of a Sand Crab #bio60

I collected this sand crab leg from the exoskeleton of a sand crab I found on Half Moon Bay State Beach earlier today. Because the entire exoskeleton itself was too large to put onto a slide, I removed the lower half of one of the legs because it was much smaller and much flatter. I…

Expo Markers #Bio60

I was having trouble seeing things clearly since a lot of what I tried to look at was too thick for light to get through. I finally resorted to drawing on a slide with Expo markers to test if that would work, and I thought the results were pretty cool. I was surprised by how much…

Andrew’s Hair (Bio 60)

I tried photographing many things with my foldscope from a dead fly (way too small to get a good look at) to a flower pedal (too thick to get enough light through). The best image I got was of my hair.

porella sporophyte – spores and elaters

this image is of a cross-section of the sporophyte of the liverwort porella - the spores are dark red and surrounded by helical elaters - the elaters function to spring the spores out when the capsule breaks

snakeskin

this image shows the ridge at the corner of one scale of snakeskin - taken with LED backlighting

vane of feather

this image is of the vanes of the tip of a feather - barbs and barbules can be seen - taken with LED backlighting

moth wing scales

this image is of the wing of a moth - the powder on moth wings is actually the scales that can be seen here - taken with LED backlighting

Flower Petal #BIO60

I collected this flower petal a few weeks ago from a flower outside my Chemistry building. The petal itself was quite rounded, so I sliced the petal sample in half so that it would lay more flat in the slide. This picture was taken a few weeks after the sample was collected, so it is…

insect wing
