Sweet little kittens brought into emergency #ilovemyjob
I'm a graduate of animal and veterinary biosciences and am now undertaking my doctor of veterinary medicine masters degree at the university of melbourne.
This blog is a record of my experiences while studying for my dream job. every all nighter, every caffeine fuelled early morning and every exciting adventure.

Big brains are all in the genes
Scientists have moved a step closer to understanding genetic changes that permitted humans and other mammals to develop such big brains.
During evolution, different mammal species have experienced variable degrees of expansion in brain size. An important goal of neurobiology is to understand the genetic changes underlying these extraordinary adaptations.
The process by which some species evolved larger brains – called encephalization – is not well understood by scientists. The puzzle is made more complex because evolving large brains comes at a very high cost.
Dr Humberto Gutierrez, from the School of Life Sciences, University of Lincoln, UK, led research which examined the genomes of 39 species of mammals with the aim of better understanding how brains became larger and more complex in mammals.
To do this, the scientists focussed on the size of gene families across these species. Gene families are groups of related genes which share similar characteristics, often linked with common or related biological functions. It is believed that large changes in the size of gene families can help to explain why related species evolved along different paths.
The researchers found a clear link between increased brain size and the expansion of gene families related to certain biological functions.
Dr Gutierrez said: “We found that brain size variations are associated with changes in gene number in a large proportion of families of closely related genes. These gene families are preferentially involved in cell communication and cell movement as well as immune functions and are prominently expressed in the human brain. Our results suggest that changes in gene family size may have contributed to the evolution of larger brains in mammals.”
Mammalian species in general tend to have large brains compared to their body size which represent an evolutionary costly adaptation as they require large amounts of energy to function.
Dr Gutierrez explained: “The brain is an extremely expensive organ consuming a large amount of energy in proportion to its volume, so large brains place severe metabolic demands on animals. Larger brains also demand higher parental investment. For example, humans require many years of nurturing and care before their brains are fully matured.”
Dr Gutierrez’s research concluded that variations in the size of gene families associated with encephalization provided an evolutionary support for the specific physiological demands associated with increased brain size in mammals.
When is it ok to get your patients drunk?
If you bring your dog to the emergency room with Ethylene Glycol toxicity and the vet pops out for a minute to the local liquor store don’t worry he doesn’t have a drinking problem!
Well he could but that isn’t relevant..He’s off to save your dogs life!
Ethanol is just the thing to use in this case as it competitively inhibits the enzyme Alcohol Dehydrogenase which breaks down ethylene glycol into toxic metabolites. So spiking a bag of IV fluids with vodka is a completely relevant way to save your dog (please don’t try this at home!) and let him excrete the ethylene glycol before it gets too nasty… your pooch may be a little groggy though!
Just had a “pretend” Clin Path case with ethylene Glycol toxicity!
You can also calm an agitated sow - one who’s likely to savage her piglets in particular - by giving her beer! #porcinemedicine101

Punctured trachea from a dog fight wound. Poor puppy got picked up by a bigger dog and got tossed around like a toy :(
Jeter is happy to say that there has been TWENTY cat adoptions so far today as part of our Cat-o-Ween event!!!!
There are still plenty of cats looking for new homes so come on down to 2 Gracie Street, North Melbourne to meet your match!
You can find more information at http://dogshome.com/cat-o-ween-half-price-cat-adoptions-this-halloween/
(at The Lost Dogs’ Home)
Wonderful event for these beautiful creatures to find homes <3 well done LDH!
Biologists are jerks.
Our sense of humor is infectious.
This post grows on you.
The Remarkable Dinosaur Footprint Wall
Located 3 miles (5 km) from Sucre, Bolivia is Cal Orko, an imposing limestone slab 0.9 miles (1.5 km) long and over 328 feet (100 m) high. On this steep face with an inclination of 72 degrees, visitors can look back in time to when dinosaurs roamed the Earth over 68 million years ago.
At Cal Orko you will find 462 distinct dinosaur tracks from at least 8 different species, totaling an incredible 5,055 dinosaur footprints. So how do thousands of dinosaur footprints come to be, on a seemingly vertical rock face hundreds of feet high? The location used to be the shore of a former lake, that attracted large numbers of dinosaurs.
The creatures’ feet sank into the shoreline in damp weather, leaving marks that were solidified by later periods of drought. Wet weather then returned, sealing the prints below mud and sediment. The wet-dry pattern was repeated several times, preserving multiple layers of prints. Tectonic upheaval then pushed the flat ground up to the brilliant viewing angle that it is today.
Behold the pinnacle of the evolution of fast, the grand champion of terrestrial velocity, the prima ballerina of deadly grace … the cheetah.
When you’re done looking under the hood, check out this amazing slow-motion video of a cheetah at full speed, from National Geographic. It is one of the most beautiful things you’ll ever watch.
I mean, just … wow:

REST IN PEACE, GIANT GEORGE - “George, a Tucson Great Dane who was once crowned the Guinness World Records World’s Tallest Dog, died at age 7, a month before his eighth birthday…”
A Great Dane in Arizona named George was the previously recognized as the world’s tallest dog. Sadly, he passed away recently at the age of seven. Thanks to his large size, Giant George gained many followers and he was beloved because of his gentle nature. Read more from the Arizona Daily Star:
George, who measured 43 inches from foot to shoulder, reigned as the record holder from February 2010 to September 2012, when he was overtaken by Zeus, a 44-inch-tall Great Dane from Otsego, Mich.
George was the star of a popular book co-written by his owner, real estate agent Dave Nasser, and made the rounds on national talk shows. His Facebook page racked up nearly 200,000 likes.
“George passed away peacefully surrounded by loved ones, one month before his eighth birthday,” a George handler wrote on his Facebook page.
“We appreciate the love and support you have given Giant George over the last several years. We look forward to honoring his spirit by continuing his charitable works.”
