Piel de un ejote

La observación de hoy fue la piel de un ejote que encontramos en la cocina. Primero corté la vaina del ejote. Después tomé un pedacito de su piel e hice la muestra. Lo que logramos observar fueron las células que forman parte de la piel del ejote.

Cochinillas algodonosas

La observación de hoy fue una cochinilla algodonosa que estaba en una equeveria. Logré ver unas unas manchitas grises y se le ven unas patas. En la parte de su cola vimos algunas líneas y unas manchas cafés. Aquí logré ver la parte central del cuerpo y se le ven algunas patas también.

Observation of intestinal mesentery of Frog

The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products like carbon dioxide. The three basic components of the circulatory system include blood, blood vessels, and the heart. Bloood is pumped by the heart and then flows through the vessels – a net work of interconnecting arteries, arterioles, cappilaries, venules, and…

Pollinators’ paradise

Bees are a rare sight in the city. They are seen as a threat, and we humans are driving them to extinction. Yet, without them no life is possible on Earth. A passion fruit vine in my garden sees scores of pollinators every afternoon. What’s admirable is that both species that visit, honeybees and stingless…

Larva de Mosquito

Esta es la observación que hice con una larva de mosquito. Logré observar la cola de una larva de mosquito y vi que en su cola tiene algunos pelos. Observé en su cabeza que tiene algunas líneas y unas antenas que son para detectar el olfato. Logré observar una línea café dentro del cuerpo y…

Pupa de Mosquito

Hola soy Rocío, vivo en Xalapa Veracruz y me estoy capacitando en Join the Node y esta es la observación que hice a la pupa de un mosquito. Aquí logré observar que en su cola tiene algunos pelos. Aquí pude observar unas líneas que son las que componen su cuerpo. Logré ver sus trompetillas que…

Thin Layer Chromatography (TLC)

Thin Layer Chromatography (TLC) is a solid – liquid form of chromatography where the stationary phase is normally a polar absorbent and the mobile phase can be a single solvent or combination of solvents. In thin layer chromatography, the stationary phase is a polar absorbent which finely ground alumina or silica particles. This absorbent is…

Cells: The Fundamental Units of Life

Cell is the unit of life. All living organisms are constructed from cell Reference: Essential Cell Biology. 4th Edition 2013; Photos experment when I have learned General Biology Labwork for 1 year.

Observaciones de plantas

Hola soy Rocío, vivo en Xalapa Veracruz y me estoy capacitando en Join the Node y esta es la observación que hice. Lo que creí que se podría ver desde los pétalos de la flor eran unas células en forma de bolitas, como si fueran cristales. Miramos una hoja de trébol, cuando pudimos verla notamos…

‘Hair’ Goes Nothing!

Intro Growing up, I always had short hair. It was barely ever longer than a classic buzz cut. I swam all the way through college, so having shorter hair was just easier since it was always getting exposed to absurd amounts of chlorine. Cue COVID, graduating college and finishing my swim career, and living with…

Roasted seaweed snack

Presented are the methods and experimentally obtained images of a roasted seaweed snack under magnification via a Foldscope. This exercise was performed as part of Stanford’s BIOE 301C: Diagnostics Devices Lab. Methods. A Foldscope was obtained and assembled using the typical procedure. To hold the sample, the paper slides with rectangular windows (Fig. 1) was…

Outer and inner onion epidermises – stained at home!

The first time I sampled an onion peel was a bit different from the introductory experiment in a biology textbook (I observed the outer epidermis, without staining it). Till now I haven’t been able to get the same “3D” effect again (https://microcosmos.foldscope.com/?p=197449), but today’s observations were equally beautiful! This time, I observed and compared the…

#EarthDay Plant Box Treasures

In celebration of #EarthDay, our youngsters headed outside to our plant boxes. We do not have open grounds since we live in the city but this did not stop them from enjoying the little treasures outside. #Kalachuchi #FoldscopePhilippines #foldscope #foldscopePH # #CitSci #CitizenScience #7lakesscience #7lakescistizenscience #7lakescitizenscientists #7lakescitizenscientiststeam

Spores, pollen, wonder and more

This is a documentation of two intended samples and one hitch-hiked sample, all very different from each other yet peacefully inhabiting the same square foot habitat. Plus one bonus sample at the end! When I first learnt about fern spores, I was intrigued by how an entire plant grew out of a microscopic grain, and…

Lilac Closeup

I examined three purple spring flowers in my yard (tulip, lilac, wild violet) expecting them to look similar at the cellular level. I was surprised how different they looked! Here is a picture of the lilac. Please see my other posts for pictures of the other flowers.

Tulip Closeup

I examined three purple spring flowers in my yard (tulip, lilac, wild violet) expecting them to look similar at the cellular level. I was surprised how different they looked! Here is a picture of the tulip. Please see my other posts for pictures of the other flowers.

Wild Violets in My Yard

I examined three purple spring flowers in my yard (tulip, lilac, wild violet) expecting them to look similar at the cellular level. I was surprised how different they looked! Here is a picture of the wild violet. What are the little alien-like tentacles? See my other posts for pictures of the other flowers.

A Camera-shy Tardigrade!

My first tardigrade – and a surprise at that. I looked into my Foldscope, and, without panning or focusing, the first thing that I saw was a slightly blurred, but recognisable little creature! Yesterday I scraped off some lichens from two trees on my street. I think they were the same kind of lichens; they…

கொசுவின் பாகங்கள்

இன்று 100% வாக்கு அளிக்க வேண்டும் என்பதை மக்களுக்கு பிரச்சாரம் எடுத்துச் செல்லப் பட்டது. ஓய்வு நேரத்தில் மடிப்பு நுண்ணோக்கியில் என்னை கடித்த கொசுவின் பாகங்கள் இவை. பார்த்து ரசிக்க கூடியது.

Scales on a gecko tail

A gecko that was sitting above my garden door took fright when I opened the door and dropped its tail. I took advantage of this situation and saved the tail for some Foldscope explorations. It was incredible to see the variability in the pigment distribution, colour and pattern on the scales. Some areas are sparsely…

I. Understanding the earliest farmers: The “crops”

Lockdown and working from home have their own advantages (let us only talk about good things). My favorite new pastime is interacting with an 11-year-old and her everyday school lessons, sometimes even as the class is done. A few days ago, the 11-year-old lectured me on the earliest farmers in the fertile crescent, the Indian…

Mosquito larva

The end of the larvae has a siphon that stays outside the water so that the larva can breath. The other is the anal segment of the larva.
