MONKEY TEACHES HUMAN HOW TO CRUSH LEAVES
he’s so concerned and seems frustrated when the leaves aren’t sufficiently crushed ha
THIS IS THE BEST THING OMG
Holy crap, these are the smallest testicles I’ve ever seen. I mean, look how freaking tiny they are; they’re smaller than peas. The doctor is going to have to put the loupe on to even see them.
Hey, you know how we have an additional fee for difficult procedures like fat dogs or cats in heat? Is there some kind of charge for this? A “nano-neuter” or a “small ball” fee?(via overheardatthevet)

The dating website eHarmony has published a wonderfully upbeat, but sadly unrealistic list of reasons why dating a veterinarian is a good idea.
So in the interests of singletons everywhere, I’ve written a few corrections to save everyone the time…
Lab mice trained to fear a particular smell can transfer the impulse to their unborn sons and grandsons through a mechanism in their sperm, a study reveals.
The research claims to provide evidence for the concept of animals “inheriting” a memory of their ancestors’ traumas, and responding as if they had lived the events themselves.
It is the latest find in the study of epigenetics, in which environmental factors are said to cause genes to start behaving differently without any change to their underlying DNA encoding.
"Knowing how ancestral experiences influence descendant generations will allow us to understand more about the development of neuropsychiatric disorders that have a transgenerational basis," says study co-author Brian Dias of the Emory University School of Medicine in Atlanta, Georgia.
And it may one day lead to therapies that can soften the memory “inheritance”.
For the study, Dias and co-author Kerry Ressler trained mice, using foot shocks, to fear an odour that resembles cherry blossoms.
Later, they tested the extent to which the animals’ offspring startled when exposed to the same smell. The younger generation had not even been conceived when their fathers underwent the training, and had never smelt the odour before the experiment.
The offspring of trained mice were “able to detect and respond to far less amounts of odour… suggesting they are more sensitive” to it, says Ressler co-author of the study published in the journal Nature Neuroscience.
They did not react the same way to other odours, and compared to the offspring of non-trained mice, their reaction to the cherry blossom whiff was about 200 percent stronger, he says.
The scientists then looked at a gene (M71) that governs the functioning of an odour receptor in the nose that responds specifically to the cherry blossom smell.
The gene, inherited through the sperm of trained mice, had undergone no change to its DNA encoding, the team found.
But the gene did carry epigenetic marks that could alter its behaviour and cause it to be “expressed more” in descendants, says Dias.
This in turn caused a physical change in the brains of the trained mice, their sons and grandsons, who all had a larger glomerulus - a section in the olfactory (smell) unit of the brain.
"This happens because there are more M71 neurons in the nose sending more axons" into the brain, says Dias.
Similar changes in the brain were seen even in offspring conceived with artificial insemination from the sperm of cherry blossom-fearing fathers.
The sons of trained mouse fathers also had the altered gene expression in their sperm.
"Such information transfer would be an efficient way for parents to ‘inform’ their offspring about the importance of specific environmental features that they are likely to encounter in their future environments," says Ressler.
Happening in humans?
Commenting on the findings, British geneticist Marcus Pembrey says they could be useful in the study of phobias, anxiety and post-traumatic stress disorders.
"It is high time public health researchers took human transgenerational responses seriously," he said in a statement issued by the Science Media Centre.
"I suspect we will not understand the rise in neuropsychiatric disorders or obesity, diabetes and metabolic disruptions generally without taking a multigenerational approach."
Wolf Reik, epigenetics head at the Babraham Institute in England, says such results were “encouraging” as they suggested that transgenerational inheritance does exist, but cannot yet be extrapolated to humans.
How does the sequester affect research?
With the December 13th budget deadline fast approaching, once again the topic of ending the sequester has come up.
One of the things not often cited are the effects on education and research funding. Some examples of this include:
- NIH (National Institutes of Health) and NSF (National Science Foundation) - Grant money has been reduced that normally goes toward research exploring how diseases spread and issues around obesity.
- UC San Diego Scripps Institution of Oceanography was affected by having to reduce the number of new science and technology centers. These centers provide long term funding to complex research such as developing new medicines or new ways to reduce energy consumption.
- The National Labs have had to reduce staff and delay major research projects due to budgetary constraints. The National Labs have a broad range of research from national defense, climate science and many innovations for clean energy.Overall this funding affects the ability for researchers to hire graduate students and post-docs. This essentially means future generations of researchers will lose out on valuable experience and training in advanced fields of science and technology.We’re urging congress to act on fixing these problems. You can also help by contacting your lawmaker or writing a letter to the editor in your local newspaper.
Signal boost, people need to know these things.
I was in JFK airport waiting patiently for my flight home to Manila when I checked my email on my phone and saw this:
I did it. I finally, finally did it. I’m going to vet school. I’m going to be a vet. I have 7 more schools to wait to hear back from, but from now on I’ll know that I have a school that will take me. The dream is real. I did it.
I’m going to vet school.
I will keep you guys posted on the rest of the details of my application process (especially what this “Taster Day” is), but for now brb crying in airplanes on my way home. Thank you so much to people I don’t know in real life who have kept encouraging me throughout this process - it means so much to me that you thought I could make it. And I did! I MADE IT! I’M GOING TO BE A VET!
Going to sleep (or not - jetlag is a bitch) with a smile on my face tonight.
