Electron Microscope Images
from the 2011 Embryology Summer Course
at the Marine Biological Laboratory in Woods Hole, Massachusetts

Every year, some of the coolest images taken during the course compete to be on the cover of an issue of the scientific journal Development

The winner was: [1] The ventral surface of a skate (genus Raja) treated with alcian blue (which stains cartilage) and alizarin red (which stains bone). The squiggly lines surrounding the face are ampullary canals, which act as an electro-sensory system.  Taken by David Gold, Lynn Kee and Meghan Morrissey and chosen by readers of the Node

Malamp: Reliquaries  >  Biological Specimens as Art
By Kyle Hill  || April 8, 2014 || DiscoverMagazine

These Frogs Are Nature’s Mistakes…And They Are Beautiful

Since 1996, visual artist and biologist Brandon Ballengée has been fascinated with the physical deformities of amphibians. As you can see, his interest goes beyond his extensive scientific research on the topic. In an ongoing art project entitled Malamp: Reliquaries, Ballengée uses the unique process of “clearing and staining” biological specimens to highlight the hidden beauty in terminally deformed frogs.

Célula Vegetal.
La cara es el Núcleo.
Las burbujas rosadas cerca del nucleo es el retículo Liso
La cosa punteada el retículo Rugoso.
En naranjo está el aparato de Golgi.

re-use of salad/lettuce hearts :)

  1. first cut it out from the leaves

  2. then cut a little from the edge but not too much

  3. then cut it into a cube-similar - cut as less leaves and material away as possible but leaves do get moldy and then the whole heart will get moldy too and die

  4. put it in wet soil so that just the tip looks out

  5. put on a plastic cup or something similar to get a high humidity around the sprouting meristem - don’t forget to give it fresh air here and there like every 2-3 days

  6. put the pot to a warm location and wait

  7. after a few days - 2 weeks the new plant will sprout

enjoy your new growing salad plants :)
I’ve tried it and it works with iceberg salad, romaine lettuce, butterhead, lollo rosso salad actually with every lettuce/salad with a heart

En français ci-dessous :)

Sensitive Plant

Mimosa pudica

"Pudica" is the Latin word for "shy" or "bashful," which is an apt description of the sensitive "Touch-Me-Not." Native to South and Central America, this shade-lover often grows as a weed under trees and shrubs. It is popular among collectors as a specimen plant worldwide, because of its unique sensitivity to touch.

The foliage retracts when touched to prevent consumption by herbivores, and it also exhibits nyctinastic movement, meaning circadian rhythms affect the leaves to close at night, and re-open during the day. 

This trait is present in many other members of the legume family as well.

You can buy seeds for this plant and grow it yourself:

Canada / USA / UK & Europe / Worldwide
