On distingue clairement des cellules sphériques plus volumineuses (Hétérocystes) qui ont la faculté de fixer l'azote de l'air pour le fournir aux cellules ( maillons plus petits de ces chaines) afin qu'elle puissent réaliser la photosynthése qui leur permet de fixer le carbone contenu daéns l'air sous forme de sucres. C'est ainsi que dès l'apparition de ce type de cyanobactéries sur Terre (1 à 1.3 milliards d'années), ces dernières ont commencé à réduire le CO2 (dioxyde de carbone) de l'atmosphère primitif (alors dépourvu d'oxygène) pour absorber le carbone et rejetter l'oxygène. C'est ainsi que s'est opéré l'accroissement de la teneur en oxygène de l'atmosphère terrestre que nous connaissons aujourd'hui.

 

Lorsque nous rejetons du CO2 dans l'atmosphère, nous détruisons nos propres ressources vitales issues de centaines de millions d'années de travail de ces cyanobactéries, auxquelles pourtant nous devons d'avoir pu voir le jour il y a à peine 1.5 million d'années. Ce processus porte un nom : AUTODESTRUCTION ...

23 shots stacked shot with a 10x microscope objective and home made tube lens. I think im getting around 5x out of the objective.

The microscope was broken but I kept the eyepiece to use as a powerful hand lens.

Low key colour image of a No. 3/A 100x magnification student microscope made by Signalling Equipment Ltd (SEL) of England.

Leitz SM Medical Microscope setup for Photomicroscopy. The microscope was made in 1958, the first year of production for this model. It includes a Swing out Abbe condenser, coaxial mechanical stage, four objectives - 3.5/0.10, 10/0.25, 45/0.65 and an OEL 100/1.30. I replaced the regular "S" binocular head with an "FS" Trinocular head. Attached to the trinocular head is a Leitz MIKAS camera adapter. The MIKAS adapter allows for the attachment of any LTM/M39 camera. In this photo I have a Nikon M-35 microscope camera attached. I can also adapt a digital camera, an M42 camera or just about any camera with the proper adapter.

taken through a microscope using phase contrast and polarized light. The size is about 70 micrometers.

Professor Christina Hydron is pleased with this new equipment... :D I bought her again recently, kinda missed her... I can't remember what happened to the previous minifig whether I sold it or gave it away...

 

The microscope is seen from one of Lynn's older photos where she bought set from a fair or something, with laboratory stuff...

We were checking out different materials under her microscope for curiosity and fun. :)

An interesting look at everyday things.

I bought a cheap USB powered Microscope and then started exploring. Some of the images were very unexpected so I thought I would post a few.

 

Held the microscope flush with an LCD screen

- The weight of the Eyepiece Tubes offsets the weight of the head so nothing is glued.

Taken with my cellphone's camera in the laboratory today, through the eyepiece of the microscope. (Sony Ericsson S500i.)

Here is just a couple of Ian's Microscopes, on show in the lounge room. He has a few more all tucked away. I know one of them was made in Germany.

Dutch photographer Maurice Mikkers is fascinated with tears. His photos reveal the structure of tears at a molecular level. In his images we see the crystallized tears, each one different, reminding us of the uniqueness of snowflakes.

this is a specimen of Expectorii maltacopescado (magnified 1011½x) with clearly identifiable nucleus, hypochondria, capacitors, noisegate, and fignuts.

it lives in the human digressive system, and typically spreads through sexual tension and not looking both ways when crossing a one-way street.

its favourite colour is brouwn.
