Insomnia, euphoria, anxiety and obsession; modern science shows us that these symptoms are just as likely to be found in someone who is deeply in love as someone who is having mental problems. Should these people be once again diagnosed as having “lovesickness”, as they would have been in the past? Or do we now have a better way to approach the connection between these conditions?...

In Africa people eat monkey meat for the protein it contains. You can guess this is bad news for the monkey population, but it actually has far bigger consequences for the whole forrest and eventually for humans themselves. It could lead to less fruits and nuts, typically those that men also eat, like mango’s.... Read more »

Male fiddler crabs face two major challenges to their dominance; attracting females, and fending off other males competing for those females. The crabs rely on an extra-large claw to achieve both these goals. However, most scientists studying these crabs have assumed that as the male crab evolved, it was forced to make a tradeoff between an attractive, long claw, and a shorter one that’s more effective in combat....

One of the many revelations about the new Pope Francis I is that he has one lung, surgically removed when he was a teenager. At age 76, clearly he has been able to function, but his condition begs two questions: can you thrive with just one lung? And, why do we have two, anyway?... Read more »

Sociological research into the world of prostitution and sex work has always been accompanied by references to the role and impact of the infamous pimp. This name, which carries with it many associations and assumptions, has actually been the source of changing and controversial meaning. A meaning that researchers like Holly Davis at the University of Edinburgh, see as badly needing explicit definition. By using data from in-depth interviews with pimps, Davis seeks “to draw attention to the problematic definitional trends, and propose new foundations for defining ‘pimp’ within social research.”...

Hey Julie, All those conferences sound completely AMAZING! I love that both dog urine and poo are totally appropriate topics for us to discuss in our conversations. All the other scientists are so jealous right now!I hope you've been well since getting home again. We've just been through the longest heatwave ever recorded in Melbourne over the past fortnight (9 days over 30oC / 90oF in a row) and today it's finally cooled off, hooray! I haven't posted you the TimTams I promised you on Twitter yet, for fear they'd melt before leaving Australia!Speaking of heat, I made a heat map of canine welfare for one of my presentation slides at the recent RSPCA Australia Scientific Seminar. It was very colourful and looked like this (click to embiggen):Cobb's colourful heat map, depicting perceived welfare levels of different dog types.This is based on data I gathered in an online survey that was conducted as part of my PhD. I asked participants to rate the welfare of different dog types on a scale of 1-5 from very poor to very good. Consequently, this image is a representation of the perception of welfare of different types of dogs rather than an indication of actual welfare. But perceptions are important! Proceedings from the day, including my full paper, should be available early next week on the RSPCA Australia website. I'll make sure to put a note up on Facebook when it does. We wish we had a quick and easy indicator of animal welfare, but we don't!My presentation covered:- the increasing expectation from the general public for transparency and best practice from industries using animals in work and sport;- how we have traditionally measured animal welfare in science;- I used working dogs as an example to talk through the life cycle stages (breeding/sourcing; raising/training; housing/healthcare and retirement/endpoints), exploring what we have learned through our recent research projects in regards to welfare, current practices and where there is room for improvement. - I also spoke briefly about research currently under way that is using cognitive bias (often referred to as testing to see if animals are optimistic/pesimistic) as an indicator of canine emotions.Yep, I actually used this image in my presentation (source) - I related the changing dynamic within animal welfare science from researching welfare outcomes (how do we understand and limit the bad stuff) toward studying affective states (how can we understand and promote the good stuff) to similar trends in other fields of research such as human positive psychology and education.So now I'm home again and focussing my attention on writing up the results of the data analyses (from that online survey) into a paper. I want to submit the paper for publication in a peer-reviewed academic journal. As you know, this can be a lengthy process. I first have to draft the paper to a standard that I am happy with; then forward it to my PhD supervisors who may (probably will!) suggest changes and redraft. I then need to decide which journal to submit it to, and format the paper accordingly. There are lots of factors involved in selecting which journal to submit to, including impact factors...

Most economists, business people and even educators and scientists assume the merits of competition; it’s supposed to lead to lower prices and improvements in quality. But, as a study on the automobile smog-testing industry shows, competition can lead to corruption and even public health problems.
A research group led by University of Southern California management professor Victor Bennett found that the structure of the smog-testing industry can lead many firms to cheat on their customers’ smog-check results. And this cheating takes place because it can actually lead to better customer relationships.... Read more »

A new study underscores a chronic problem in American (and European) society; a lack of scientific literacy. A recent study from the universities of Bristol and Cardiff found that science was one of the most difficult-to-understand topics by the average reader (environmental issues, politics, economics and religion topped out the rest of that list).
Unfortunately, these are issues somewhat vital to functioning in complex society. So, what’s the problem? Why is science in particular, so hard to understand?... Read more »
When he was running for the U.S. Senate last summer, Rep. Todd Akin, a Republican from Missouri, made a huge gaffe; he claimed that female rape victims’ bodies “just shut down,” preventing pregnancy from occurring. Therefore, according to that logic, any rape that resulted in pregnancy was, instead, consensual. His statement was in support of proposed policies that would restrict the availability of abortion even in the case of rape or incest.... Read more »

Why does gay and lesbian sex exist? If the purpose of sex is reproduction, it makes no evolutionary sense. But recent work by a group at Uppsala University in Sweden has turned that notion on its head.

I grew up going back and forth between New Jersey and New York City, which often meant going over a bridge. And that is probably my earliest memory of sitting in the car wondering, what if we drive off this bridge? Years later I would find my way to the top of sky scrapers and spires overlooking cities around the world, naturally to marvel at the view, but each time with that strange familiar thought, what if I jump or fall off this building?

Together with getting married and buying a house, the decision to immigrate is one of the most important decisions that a person can make. So, it’s important that immigrants feel that they have satisfactory input into the process of deciding whether or not to migrate.
