2000s – Significant advancements in real-time 3D imaging

Medical imaging took a noteworthy step forward with the introduction of the capacity for 3-dimensional imagery during the early 2000’s. Enhanced computer software and imaging devices, such as the CT, PET, and MRI scans have provided researchers the ability to view target areas with exceptional levels of detail further reducing the necessity for vivisection. 3D […]

1983 – Polymerase Chain Reaction developed

Since its original development by American biochemist Kary Mullis in 1983, the Polymerase Chain Reaction (PCR) has become one of the most widely used and important technologies in molecular biology.  The ability for researchers to target a specific section of DNA and recreate multiple copies of identical sequences provides an invaluable tool for a variety […]

1980s – CR, MRI, and colour Doppler ultrasound imaging developed

Major advancements in medical imagery took place in the 1980s with the advent of Computer Radiology, Medical Resonance Imaging, and Colour Doppler ultrasound. Each technology varies in its conception and applications, yet all would prove pivotal in the movement towards non-invasive techniques for diagnosis, surgery, and drug testing.

1907 – Harrison grows from nerve cells by ‘hanging drop’ technique

The turn of the century witnessed an influx of cell culture in experimentation. However, few of the advancements made were as pivotal as the work conducted by Ross Granville Harrison at Johns Hopkins University in 1907. To this point, in vitro work had become quite good at observing organic tissue microscopically, however, attempts to manipulate […]

1895 – Discovery of X-rays

German physicist Wilhelm Rontgen is recognised as the first individual to study the properties of X-rays in 1895. Roughly a decade later, X-rays would be adopted as a medical tool to non-invasively observe patients. The ability to study a subject without the need for vivisection provided an important new alternate methodology to many animal studies. […]

1885 – Roux maintains embryonic chick cells in saline solution

The groundwork for modern tissue culture was established in 1885 by German Wilhelm Roux. An embryologist who studied developmental mechanics, Roux was curious about the evolutionary machinery at the cellular level. Roux’s work to isolate the medullary plate (a key structure in the developing nervous system) of a chicken embryo and sustain the cells’ viability […]

1677 – van Leeuwenhoek’s early work on microscopy validated

Dutchman Antonie van Leeuwenhoek’s ground-breaking early work on microscopy and observations of single-celled organisms has him fondly referred to as the ‘Father of Microbiology’. A talented lens-maker and passionate naturalist, Leeuwenhoek pioneered the process of identifying microscopic organisms under his own hand-crafted microscopes. He referred to his findings as animaluculs. This paved the way for […]
