Is Parapsychology a "Taboo" Subject in Science?

by Scott McGreal in Eye on Psych

An opinion piece recently published in Frontiers in Human Neuroscience, endorsed by 90 signatories calls for a more “open-minded” consideration of the subject. What particularly struck me about this piece was the claim that investigation into the subject is not just controversial, but actually “taboo”. Examination of the history of parapsychology indicates that the scientific mainstream has shown considerable open-mindedness towards the subject, and that claims that it has been treated as some sort of “forbidden” topic are both hyperbolic and disingenuous....

Stereotypical dogs: repetitive and pointless?

by Cobb & Hecht in Do You Believe In Dog?

"I'm a labrador" does not = "I'm hungry" (source)Hey Julie,it's great to get an updated view of what's on the canine science cards for you in 2014 - looks like we're both going to be keeping busy - and wouldn't have it any other way!I can't believe we're already into February, to be honest. There are so many great new publications coming out, it's quite exciting to be able to share them with you here! You know I'm always thinking about the welfare of kennelled dogs (because PhD!) and I noticed a new study from the University of Bristol titled Repetitive behaviour in kennelled domestic dog: Stereotypical or not? (reference given below). Now of course, you know we're not talking about "all labradors are greedy" or "all little dogs are yappy" kind of stereotypes here, we're talking about describing a specific type of behaviour.I know you're interested in stereotypical animal behaviour too, so I wanted to share this with you! As you know, stereotypical behaviours have traditionally be thought of as repetitive and invariant behaviour patterns with no obvious goal or function.  Typical stereotypies that many people would be familiar with, include elephants in zoos/circuses swinging their trunks and/or swaying side to side; horses 'weaving' in stables; and bears route tracing when in captivity:In these situations, it's generally understood that the behaviour is the result of the animal feeling frustrated, fearful, restrained, stressed or lacking stimulation and when seen frequently, is often considered an indicator of poor welfare. Determining whether such behaviours are 'without function' has proven difficult. Research over the past decade has shed more light on the reasons animals might develop these behaviour patterns, and suggests that performing the behaviour is not always without a function, but can actually serve a role in helping animals to cope. We have discovered that the animals showing frequent stereotypical behaviour may not be the individuals suffering the most (you know that old saying - it's the quiet ones you've got to watch!).   As such, a refined definition better separates 'abnormal repetitive behaviours' from 'stereotypical behaviours' (which are considered to be caused by inadequate housing that causes frustration and may be overcome with appropriate change of environment including social and/or environmental enrichment). Dog-focussed research in this area has shown that kennelled dogs kept in restricted environments (such as laboratories or rescue shelters) may show behaviour as pacing, circling, spinning, wall bouncing or barking:The new research from Bristol set out to investigate if every dog observed in a working dog facility showing repetitive behaviour could really be described as stereotypical (which would suggest they were experiencing compromised welfare). The researchers examined the behaviour and physiology (using the urine's cortisol/creatinine ratio) of 30 German Shepherd Police dogs. They saw repetitive behaviours in over 40% of the behavioural samples in response to ten deliberately arousing activities (such as a kennel staff member standing outside the kennel yard, clicking the clip of a leash - indicating exercise time; or a full food bowl being placed outside the front of the kennel enclosure; or a stranger walking through the kennel complex). Only two individual dogs were not observed performing any repetitive behaviour.The study confirmed that dogs housed in kennel facilities long-term commonly exhibit repetitive behaviours when presented with a variety of routine activities as stimuli; also showing that individual dogs differ in the way that they respond.Some dogs only engaged in repetitive behaviours only during husbandry events when a person was there. Most dogs showed more than one of: circle, spin, bounce, pace, generally in some kind of combination (the spin an... Read more »

Poo Power! Global Challenge

by Cobb & Hecht in Do You Believe In Dog?

Hey Julie,it's not every week I get to issue an invitation to the entire world, but that's exactly what I'm doing today! MiaStudents invited to compete in global dog poo competition:Poo Power! Global Challenge launches Monday 25 November 2013Students and classes will be pitched against each other to see who can identify the most and largest dog waste 'hotspots' in their local neighbourhood in the 'Poo Power! Global Challenge'. Participants use a GPS-enabled iPhone to download the free Poo Power! App from the App Store. Their task is to identify and map dog poo 'hotspots' in dog parks and public spaces from their neighbourhood from Monday 25 November 2013.  While the initial competition is being run for students and schools, anyone, anywhere can participate and contribute to this citizen science initiative.Duncan & Diesel from Poo Power!This eyebrow-raising project is a collaboration between dog poo entrepreneur Duncan Chew from Poo Power! and me (!), as a way to say thanks to all the students who voted for me to win I'm a Scientist, Get Me Out of Here! in Australia recently. The collected information will be uploaded onto the Global Poo Map and provides a platform for students to discuss the scientific, social and environmental issues of dog waste. The students are then encouraged to write a letter to their local Government representative of their findings and recommendations. Citizen science at it's finest! Scientific American are currently featuring Poo Power! on their Citizen Science website"From our research only 3% of Australians see uncollected dog waste as an environmental concern," explains Duncan Chew. "When it rains, uncollected dog poo gets washed down drains, effecting water quality and habitat for native animals, as well as making rivers and creeks unpleasant for us to visit."  I just think this is a great way to utilise the prize money from winning the I’m A Scientist – Get Me Out of Here! competition; it raises awareness of new sustainable energy sources, environmental issues and responsible dog ownership, all while increasing student engagement in a citizen science activity.The collated information has the poo-tential to identify sites for biogas-powered lights for parks as proposed by the Melbourne-basedproject, Poo Power!, currently in development. The methane that is released from the dog waste as it breaks down inside a 'biogas generator' can be used as a viable renewable energy source.Photo: Steven PamCompetition prizes and giveaways are up for grabs for students whose submissions are received between 25th November and 9th December 2013. After this initial competition period closes, the project will continue to run, collecting ongoing hotspot data worldwide.... Read more »

Biology of Love: are we made to live happily ever after?

by Koko Beers in United Academics

While we learn from songs, movies and fairy tales that life is all about finding the perfect partner, about romance, soul mates and lifelong relationships; biology tells us otherwise.

Neuroscientists and neurobiologists have looked at the neuronal correlates of love, using brain imaging techniques and animal models. Reviewing various studies, Dutch researchers explain the evolution and neurobiological factors of our romantic love. Learn what evolution, biological substances and the course of relationships tell us about human relationships. Is romance and monogamy nothing but a myth?... Read more »

When equipment fails: paws and assess

by Cobb & Hecht in Do You Believe In Dog?

Photo: Steven PamThere is an industry in Australia that relies on an integral piece of equipment, but the system behind product development process is flawed, and lives are at stake. From farm dogs to military explosive detection dogs, guide dogs to greyhounds, Australia’s working and sporting dog industry claims a 50-70% fail rate as normal. The welfare of these dogs is intimately linked to their working performance. It can be an emotive topic, so let’s take the emotion out of it and objectively consider current practice.A diverse industry, with four sectors operating in different domains, is dependent on one key piece of equipment. A tool that can vary in price from free to $40,000, can be purchased new or second hand, but is unequivocally required to get the job done. Hundreds of thousands of units are currently used daily throughout Australia in government, human health, sporting and private operations.SourcePractitioners invest resources in this equipment, only to find that the tool doesn't work. It’s unsuitable. It operates at the wrong speed. It breaks. It just doesn't do the work it was meant to - at least half of the time! In some industry sectors, the equipment fail rate is estimated as high as eighty percent. Waste units are disposed of and new ones sourced. Perhaps from a large scale manufacturer, perhaps from a private artisan, or some people go ahead and take a crack at making their own. Recycling within the industry is extremely low, at less than ten percent. The production of this equipment is currently inefficient; the industry has no validated minimum standards in place and the product lacks quality assurance. From an industry business and performance perspective, what should be done? A review of the purpose and production life-cycle analysis for this tool seems indicated? Absolutely. A review of how the equipment is being employed, handled, maintained and stored by practitioners? Yes. Perhaps a review of the training courses and educational materials available to the practitioners and the people who train them? For sure.SourceWithout objective review and subsequent improvement, this industry is leaving itself open to scrutiny by the media and risks losing public support. Review of this kind is common. In industrial design and quality management fields, validation of product integrity, ongoing review and updating of evidence-based best practice are standard. Re-purposing of surplus or malfunctioning stock into other areas rather than directly to landfill may require additional resources. However, this extra spend is important as tolerance for unnecessary waste in the 21st century is limited. Indeed, the sustainability and economic viability of this industry into the future relies on improved accountability, higher transparency and demonstrated responsibility.We owe this commitment to review and refine the production, management and education surrounding this device to the industry, the people involved and the tasks they achieve. It’s sound business practice. And we owe it to the dogs.Hi Julie,I wrote this because I wanted to consider if there was a good case to be made for improving the welfare of working dogs, without the emotion or emotive slant often inherent in animal welfare discussions. This came about after recent conversations with people who have suggested my work towards improved working dog welfare is based on me 'loving dogs' or having bleeding-heart, idealistic expectations about the way dogs should be cared for. I hope I have been able to demonstrate that this is a) not about me, and b) that a good argument for objective review and assessment of how working dogs are produced can be made, even before adding consideration for the fact these are sentient animals with capacity to thrive or suffer as a result of how we manage their lives.I'm looking forward to continuing these conversations at the Working Dog Conference 2013 next week.Wish you were here,...

To Call a Player’s Poker Hand, Look to the Arms

by amikulak in Daily Observations

Professional poker players rely on the ability to divorce their facial expressions from their emotional state – no matter how good, or how bad, their hand is, they have to maintain an inscrutable “poker face.” But new research suggests that they may do well to focus on another body part: The arms. The research, published in Psychological Science, suggests that homing in on only the player’s arms may be the most reliable way to call a bluff.... Read more »

The Selective Clearance of Senescent Cells – a Promising Target for Ageing

by Robert Seymour in NeuroFractal

When cells are put under stress (e.g. UV light, ionising radiation, reactive oxygen species) they undergo a process known as cellular senescence in which cell division (mitosis) is arrested. This is thought to contribute to ageing. In their 2013 paper Naylor and colleagues outline a strategy to selectively remove in vivo senescent cells expressing p16Ink4A .... Read more »

Researchers Discover Link Obesity And Liver Cancer

by Pieter Carrière in United Academics

Is life worth living? It all depends on the liver, postulated ‘Father of American psychology’ William James (1842-1910). His famous quote underlines the central role the liver plays in detoxification, digestion of lipids, storage of nutrients to maintain homeostasis and so on.

Sadly, liver cancer is one the most common cancers worldwide, with 750.000 new patients each year and presumably causing almost 700.000 deaths annually. These figures reveal that liver cancer is extremely lethal and we need to understand more about its etiology.... Read more »
