H&E Staining

submitted by: abnova

Abnova - H&E stain is a popular staining method in histology. Its a combination of two dyes: the basic dye (hematoxylin) and the alcohol-based dye (eosin). In an H&E stain you will usually see both eosinophilia and basophilia: the nuclei of cells basophilic (blue), while eosinophilia is typical of cytoplasmic constituents (pink).

Lightweight Energy Efficient Self Balancing Two Wheel Car or Transporter

submitted by: Clem
The Video shows a demonstration model of a self balancing two wheel car. The "car" would be very, very much lighter than our current cars, and use much less fuel, with consequent reductions of energy, and therefore the production of green house gases. The vehicle could run on electricity, or have a small petrol/gas motor. Indeed, the wheels themselves could be part of a large electric motor. The video shows quite a small cabin in between the wheels - I would envision a larger cabin -...

Ecological Economics: Economy Out-Growing Earth

submitted by: kanaan
This is a public awareness activist skit that was demonstrated on the streets of Granville Island in Vancouver, BC. Our current economic system relies on constant growth to ensure functionality. This skit is meant to show that infinite economic growth is unreasonable on a finite planet. Our Earth cannot keep up with our ever-increasing needs. While scientific progress will provide great advances in technology, innovation alone will never resolve the problem of the overconsumption of our...

Antibody Conjugation-Biotinylation

submitted by: abnova

Abnova - Antibodies labeled with biotin provide the user with a tool for increasing the sensitivity of an assay by its ability to amplify a given reaction. A biotin/streptavidin (avidin) system offers low background, enhanced sensitivity and the ability to detect minute amounts of antigens. For more videos, visit Abnova!
