Ruwaidix / A moving scientific archive
Moving evidence.
The zebrafish heart is difficult to describe from a still image. These short recordings let me revisit its motion, the apparatus used around the laboratory and the sound of a colleague explaining a reaction.
01 / Observation of living systems
Under the microscope.
Three short recordings show zebrafish under the microscope. Movement can be observed directly, although its scientific interpretation depends on the imaging conditions and associated measurements.
Cardiovascular microscopy
A recorded cardiovascular sequence in a zebrafish. The motion is visible; quantitative assessment of function requires the associated experimental measurements.
A second cardiovascular sequence
A second zebrafish microscopy sequence shows cardiovascular movement.
Zebrafish optical microscopy
A further view of zebrafish movement under the microscope.
These recordings preserve cardiovascular motion under the microscope. The related 2018 ATVB study addresses endothelial primary cilia and vascular development; the clips are not labelled as reproductions of its published figures.
02 / Developmental models
An avian preparation.
A separate short recording from chick-embryo work. It belongs to the avian research archive rather than the zebrafish primary-cilia narrative.
Chick-embryo preparation
A brief film of an opened avian egg preparation. Its specimen details, timing and precise procedure have not been independently reconstructed from the surviving clip. No developmental outcome is inferred.
03 / Instrumentation
The machinery between results.
The camera stayed on a piece of laboratory apparatus while it moved. It was the sort of routine activity that rarely reaches the figures of a paper.
A laboratory apparatus in motion
The recording shows a pump-like assembly moving beside laboratory equipment. The apparatus is shown as recorded.
04 / Chemistry explained aloud
At the reaction board.
Khaled Jama Mohamoud explains a chemistry reaction associated with his thesis in this original recording. His spoken explanation is preserved with the video.
A reaction explained by a colleague
Khaled Jama Mohamoud speaks about the reaction associated with his thesis. The video retains his original audio, as recorded during the discussion.
05 / Institutional record
Research across institutions.
Qatar University Research's recorded seminar discusses international research collaborations through the Qatar University and Medical College of Wisconsin partnership. It is an institutional recording, not original footage owned by this site.
A recorded institutional seminar
The university seminar examines opportunities and challenges of international research collaboration. Its relevance to this archive is the institutional setting of the zebrafish vascular-development work, not a claim that the whole seminar documents the author's individual experimental activities.
