Wild Dog Thought To Be Extinct Rediscovered In The Wild

We’ve heard of many animals gone extinct – the dodo, the Tasmanian tiger; and we’ve heard of many being rediscovered by scientists after decades of ‘extinction’. This miraculous feat has once again been achieved in 2016, confirming the existence of another species previously thought to be extinct.

For over 40 years, the New Guinea Highland Wild Dog has been thought to be extinct in the wild. They are believed to be one of the rarest and most primitive species of canines, and a variant of the New Guinea Singing Dog (Canis dingo hallstromi) – the two are thought to once be the same species, before humans took wild dogs from the highlands and bred them into the Singing Dogs we know now. Although the Singing Dog are still bred in zoos, little has been heard of the Highland Wild Dog. However, in 2016, this all changed.

Lung Organoids

Organoids, it’s in the name. They are 3D, miniature and basic versions of organs that help scientists further understand the anatomy and function of various organs. Recently, researchers of Columbia University Medical Centre have created miniature lung organoids (as seen in the image bellow) to aid their knowledge on treating various diseases.


So how are they made? Technology has rapidly improved in the past 7 years and has been used for research in order to help scientists improve their understanding on biological functions. This technology began with attempts to create organs on a dish, which started as a dissociation – reaggregation experiment lead by Henry Van Peters Wilson. The results of this experiment showed that sponge cells could re-organise themselves after being separated, back into one whole organism. After this experiment, there were many similar experiments that were able to generate different types of organs artificially through the dissociation and reaggregation of organ tissues. These experiments often used amphibians as their subjects.

The Dimensions Of The Universe

Have you ever wondered whether or not parallel universes exist? And if they do, how is it possible? To answer this question, let’s take a look at the notion of dimensions. Dimensions are simply the different facets of what we perceive to be real. We live in a three dimensional world and are familiar with the components that make up the three dimensions – that is we see objects in our immediate world as having a length, width and depth.shirley two.png

However, it seems that the three dimensional world is not the limit. In the light of string theory, scientists now believe that there may be many more dimensions beyond the three we are familiar with. In fact, the string theory postulates that it could be possible that 10 dimensions exist in the universe.
