Carl Sagan guided the maiden voyage of Cosmos a generation ago. He was the most successful science communicator of the 20th century, but he was first and foremost a scientist. Carl contributed enormously to our knowledge of the planets. He correctly predicted the existence of methane lakes on Saturn’s giant moon Titan. He showed that the atmosphere of the early Earth must have contained powerful greenhouse gasses. He was the first to understand that seasonal changes on Mars were due to wind-blown dust. Carl was a pioneer in the search for extraterrestrial life and intelligence. He played a leading role in every major spacecraft mission to explore the solar system during the first 40 years of the space age.
Raise your hand if you think the best part of the new Cosmos were the amazing shots of Carl Sagan’s life and work.
I love you Neil, but so many Carl feels.
"This video shows a rabbit heart that has been kept beating outside of the body in a nutrient and oxygen-rich solution. The new cardiac device — a thin, stretchable membrane imprinted with a spider-web-like network of sensors and electrodes — is custom-designed to fit over the heart and contract and expand with it as it beats."
What Are The Odds? – Kermode Bear
The Spirit Bear is actually a white Black Bear, which sounds funny and incredibly contradictory but it is the truth. They are not albino and as such don’t have the pink eyes that is normally associated with albino animals, rather the colour of their fur is a result of two recessive genes being expressed. It is believed that 1 out of 10 Black Bears carry this recessive “white-coat” gene, so in theory, they should be able to exist anywhere that Black Bears live. Interestingly enough, the main population of Kermode Bears can be found on the islands off the coast of British Columbia, Canada in a temperate rainforest appropriately named the Great Bear Rainforest. The population of Spirit Bears is most likely greatest in this area as a result of conservation efforts of the First Nation tribes. These groups valued the Kermode Bear and as such didn’t hunt or trap this beautiful creature. As a result it is believed that the population of the Spirit Bear is between 400-1000 individuals in this area. How is that for proof that animal conservation can truly help a species (or sub-species) survive.

I really dislike the way this and most articles are written about the Kermode Bear so I am also going to link in the well known Nat Geo article for a full understanding.
- occurs mainly in elderly constipated patients
- colicky abdominal pain, rapid dilation of sigmoid loop
- abdominal distension
- AXR - "coffee bean sign" = dilated sigmoid colon
- Risk of necrosis and perforationif left untreated
- Management - passage of rectal tube (causes passage of flatus + faeces), if this fails surgical untwisting of volvulus
- Repeated sigmoid volvulus = elective resection of sigmoid loop
