The Warrior Gene, Back from the Grave

by nooffensebut in The Unsilenced Science

Recently two meta-analyses on the gene, monoamine oxidase A, and its relationship with violence came to opposite conclusions. I review those studies and pose the questions that the scientists were too afraid to answer.... Read more »

Revealed: The Secret Of An Intellectual Brain

by Shyamali Sharma in Workout Trends

“Do you love to write? I do… Do you prefer typing rather than writing? I do…” Well, I might sound like a bride standing on the altar in front of my groom. The priest asks me the most obvious questions and I nonchalantly reply, “Yes, I do.” Students and tech savvy people are also most likely […]

The Bigfoot Question: A Genetic Analysis of Yeti Hair

by Melissa Chernick in Science Storiented

It’s been a while since I’ve written about Bigfoot, and that’s a shame because he’s pretty fun to write about. As with many things, I like to keep it in a scientific context. That’s why I was pretty stoked to see a recent Sasquatch paper in Proceedings of the Royal Society B. A paper that takes an interesting approach: genetics. Right off the bat the paper does not assume non-existence, both pointing out that there are numerous reports and sightings yet no bodies or recent fossils. Theories abound about what these animals are, ranging from surviving populations of collateral hominids to unlikely hybrids. As a general rule, modern science shies away from the yeti-finding field, to the point that they make believers feel rejected. Admittedly, believers have point in that science should not accept or reject anything without examining the evidence and testing hypotheses. Pretty much the definition of science, right? So that's what authors Sykes et al. do, take a scientific approach.The researchers collected a total of 57 Bigfoot hair samples submissions from museum and individual collections. They went about it all officially with a joint press release in May 2012 by Museum of Zoology, Lausanne and the University of Oxford. Then, to eliminate obvious non-hairs, they subjected the samples to macroscopic, microscopic and infrared fluorescence examination. Based on provenance or historic interest, thirty-seven of the samples were selected for genetic analysis. Hairs were first cleaned to remove surface contamination - just consider how many people had handled a sample, so you need to eliminate known human DNA to leave just sample DNA. The meticulously cleaned hair samples were then ground in a buffer to homogenate, incubated with proteinase K, and extracted for PCR amplification. This amplification was of the ribosomal mitrochondrial DNA 12S fragment corresponding to bps 1093-1196 of the human mitrochondrial genome, using a permissive primer combination that allows for a wide range of mammalian DNA. The results were then compared to GenBank accessions for species identification.Perhaps it is important to point out what the 12S mitochondrial DNA is and how it works. Even within fur-bearing species, there is a large amount of variation in hair appearance that can be identified under the microscope to determine species. But, in the absence of an experienced hair examiner (yes, those exist), a reliable, alternative analysis must be used. This analysis comes in the form of highly conserved mitochondrial DNA regions, these are particular sequences that have been maintained by evolution despite speciation, probably because they are functional. Mitochondrial 12S ribosomal RNA has an amplification size that renders it useful for even problematic and/or degraded samples. Highly conserved primer regions and the high nucleotide species diversity present within the portion of the 12S gene examined allows for identification at least to genus and often species. Studies examining the extent of 12S homology within and between species have shown a high degree of confidence in the test's ability to match species from biological samples, usually hair. This includes primate homologies like the chimpanzee, who shares a 98% homology with the human 12S region, Gorilla (97%) and rhesus macaque (90%). These studies have shown that it is unlikely that a non-human primate hair could be confused with human hair using this system.Now knowing all of this, back to the results of the Bigfoot study. Despite multiple attempts, seven of the samples yielded no DNA sequences, leaving the researchers with 30 samples. These 30 samples were each matched to a known species. Ten belonged to various bear species, four were cows, four were horse, four were wolves/dogs, two were raccoons, one was a deer, one a Malaysian tapir, one a sheep, one a serow, and one was human (exact match).There has been quite a few articles in the news about this study, and that’s good because this paper is a nice example of using hard science to test a theory. It is also works towards bridging the gap between two rather disparate groups of people. So kudos to you Sykes et al. Sykes, B., Mullis, R., Hagenmuller, C., Melton, T., & Sartori, M. (2014).

Igniting Sparks, Surviving Fireworks and Dog Science July!

by Cobb & Hecht in Do You Believe In Dog?

Hey Julie, well, here I am, back in chilly, wintry Melbourne. #SPARCS2014 was an amazing event - such an intense three days with early feedback suggesting over 40,000 people joined in online for canine science, excitement, wonderful researchers and inspiration!  You've done a great job capturing the essence and feedback of this international conference over at DogSpies on the Scientific American Blog Network. I'm so pleased someone took photos, or I think I would have convinced myself it was all just a rather lovely dream! I loved our time together in Rhode Island and New York - especially the bit where we ate Peter Pan donuts and talked about - actually, all I remember now is the original glazed. Ahhhh. Donnuuuuttttttttttts.I'm betting we were probably talking about what a crazy month July is shaping up to be - and by crazy, I mean in all the best ways. We've both returned home only to launch into full conference-prep-mode the Canine Science Forum (this year also featuring, for the first time, the Feline Science Forum) July14-17th - people can follow on Twitter @CSFFSF2014 at #CSFFSF2014.I'm excited that we are both sharing our own research at the conference in the form of oral presentations and posters, so we've both got plenty to prepare. I've enjoyed reading over the newly-released Scientific Programme to see what other topics are being presented! These 30-ish original research presentations represent the latest in our field in the two years since the 3rd CSF in Barcelona (where we met!) as well as the introduction of a new 'Controversies in Canine Science' talks (with topics like 'To what extent does hybrid vigour exist in dogs?'). Talks are sure to ignite more passionate discussions, like those we enjoyed in the panel discussions at SPARCS 2014. With just two weeks to go, I'm thinking things might get a little quiet here on the blog as we focus on preparing to share our research. I know I am going to need every spare moment to get organised and travel to the UK where I also get to see my gorgeous sister in law get married before we meet up again in Lincoln. I hope everyone who enjoys our blog will keep in touch with our updates on Facebook and Twitter during July.Perhaps it's a good time to review some posts from our archives? So much great canine science discussed over the two years since we launched the Do You Believe in Dog? project. It's actually really fun to reflect on how much we've shared in the course of writing to each other. With 4th of July hitting various parts of the world this week, I'd probably recommend the series of posts we've both contributed to about helping our canine companions with fireworks:Fireworks: not fun for everyone (or every dog)What kinds of dogs are troubled by fireworks, and what to do about itHow to make fireworks less upsetting for dogsI'm going back to drafting my presentation powerpoint for #CSFFSF2014 now Julie - see you in Lincoln, UK soon!Mia...

What the pug is going on?

by Cobb & Hecht in Do You Believe In Dog?

Hi Julie,thanks for that awesome list of canine-related citizen science projects that anyone can sink their teeth into. I have a question for you: What do you see when a pug comes into your field of vision?I'm asking you because (at the risk of inciting wrath of many) - honestly? I'm really bamboozled by some pedigree breeds and their popularity with so many people. How I feelI'm not hating on pugs or pedigree dogs, and I don't mean any offence to people who hold their love of pugs close to their hearts. I really don't. I appreciate some people are very passionate about breeding certain kinds of dogs. I don't mean them disrespect. I think I just see dogs differently to them.Pugs do make an excellent example to lay on the table for discussion when we consider inherited health and welfare issues in dog breeds. We could just as easily choose to look at any other breed where physical characteristics have been strongly selected for, like the Dalmatian, Great Dane, British Bulldog, Basset Hound, Dachshund, German Shepherd, Shar Pei, Pekingese, Neapolitan Mastiff... I could go on... but let's take the Pug as a case study today.Flickr/pugSo tell me - what do you see?Flickr/HelenMcDonaldI see a companion dog who can't really fit into the body we've given it. And by 'the body we've given it', I mean that through successive generations of human-dictated breeding that selects for an increasingly shortened muzzle (flat face), round head, big eyes, curly tail and rolls of skin, we've changed the face and body of pugs from this...Pug circa 1890 (source)...to this. I'll grant you this is an extreme example, but by golly, the fact that we've produced a dog lacking a defined muzzle like this makes me worry for the health and welfare of the dog. This dog really has no discernible nose or muzzle: Dogs should not have a concave face (source)Does it matter? Well, if you DON'T want a dog that can breathe effectively, maybe not. The (in)ability to breatheAlthough of course, it kind of makes for a sucky life for the dog. Not being able to breathe or moderate their temperature easily. I don't think many people in chronic respiratory distress report it feeling great. I don't think it's unreasonable to extrapolate that it causes dogs similar discomfort. The compromised breathing of these dogs isn't (as the tags on YouTube might lead some to believe) funny, nor ...

Preventing dog bites when you don't have a hero cat

by Cobb & Hecht in Do You Believe In Dog?

(source)Hey Julie! So much going on I need to take three deep breaths to calm down! Firstly - we have a winner! Actually - thanks to the awesome crew at SPARCS, we have two! Very excited to meet Marsha P and Kristi M at #SPARCS2014 and want to thank all the excellent people who responded to our giveaway shoutout on Facebook, Twitter and Google+. We hope those of your who weren't successful will consider still coming along or joining us on the livestream broadcast. Secondly - I loved learning about the differences in UK and US shelter workers perceptions of pit bulls and all the associated bits and pieces that went along with that in our latest guest post by Dr Christy Hoffman. Really, really interesting research and I look forward to the next piece of the puzzle (aka 'new science') in that area.Thirdly - it's dog bite prevention week in the USA right now! We can't all own Tara the Hero Cat (and to be fair, as much as she is worthy of her notoriety and 20million+ hits on the viral video showcasing her ninja skills, she didn't actually prevent the bite - although I'm pretty confident she helped prevent it being a whole lot worse). If you somehow missed what on earth I'm talking about - check out this clip of amazing Tara (but a warning, it does show security camera footage of a child being attacked by a dog and the subsequent wounds): Which brings us back to Dog Bite Prevention Week. We don't have a week like this in Australia, so I did some web trawling to check out what you guys have going on over there.  The AVMA have put up a whole lot of great information and resources about dog bite prevention, including this neat summary infographic: I was really pleased to see this analysis of information about the role of breed in dog bite risk and prevention, which reminded me of this piece on The Conversation by researcher Dr Rachel Casey from Bristol University in the UK, who has been part of a team investigating aggressive behaviour in dogs. The research highlights similarities across Australia, the UK and the US with most serious dog bites occurring to children by a known dog in a familiar area without direct adult supervision at the time of the attack. But of course - as Hero Cat Tara has shown us this week, not all dogs stick to these trends. It seems that there are many commonalities to serious dog bites that we can all be aware of to help reduce the risk, given that any dog can bite: Supervise children <14yo around dogs, even known dogsDon't try to pat a dog you don't know, even if it is on the other side of a fenceMake sure your dog is well socialised and trained in basic commandsKeep your dog healthyTeach your children to be mindful and careful of their actions around dogs, especially when the dog is tied up, eating or sleeping...

Finally Solved: Why Zebra’s Wear Black And White Stripes

by Chiara Civardi in United Academics

The origin of zebra stripes has long been a mystery: in over a century, scientists developed various hypotheses. Social factors, cooling mechanisms and camouflage against predators, were proposed as possible explanations. However, no striking evidence could support one particular theory, so the black and white striping in zebra was believed to remain a grey area.... Read more »
