Today: “The end of men? Expert predicts males will be extinct in five million years… and the process has already started!” by Daily Mail. Last week, Daily Mail published a story on research conducted by Dr. Jenny Graves, Distinguished Professor of Molecular Science at La Trobe University, Melbourne. According to the story’s headline and taglines, males are basically living on borrowed time. “Professor Graves, one of Australia’s most influential scientists, believes that women will win the battle of the sexes – and in the most definitive way possible.”...

When observing homosexual behavior in animals, are biologists too quick to explain the gay away?
Two years ago, public outcry occurred when the zookeepers at Toronto Zoo separated Buddy and Pedro, a ‘gay’ penguin couple. The African penguins had been together for years, but were split up in the hope that they would find a female mate and produce some offspring. A necessary evil, the zookeepers explained, as the African penguin is an endangered species.... Read more »

A lot of people study intelligence, or at least take it for granted. We speak, listen (sometimes—more on that in a bit), form social groups that other animals don’t. Pretty smart, eh? But humans also do some colossally dumb things—engage in unnecessary stereotyping, stick our tongues to a frozen pole, or trigger a worldwide financial crisis.... Read more »

The paper was a bombshell. Felisa Wolfe-Simon, a microbiologist at the US Geological Survey and NASA, found very strange bacteria in a very strange lake that energized itself in a very strange way. The bacteria lived in Mono Lake, California, and used the usually toxic chemical arsenic to sustain life, whilst most other living things used the chemically similar phosphorus.... Read more »

I guess you would be pretty surprised if you went to a psychotherapist and he or she started crying. But it sounds weirder than it actually is. In a survey among 684 American psychologists and trainees it turned out that most of them shed tears during therapy. And this wasn’t a women’s issue.... Read more »

Oral films have gained interest in the last couple of years. Films for oral application offer an interesting new approach for drug administration. Active pharmaceutical ingredients (API) can be implemented in thin-sheeted polymer film matrices. These dosage forms are intended to be placed in mouth to dissolve in the saliva without the need of additional liquid and without swallowing of a solid dosage form.... Read more »

How do you catch a dragon? Do you go looking for a brave knight to send forth on a difficult quest? Or a legendary hunter without fear?
No. You use cameras to capture their image.
To be clear, the dragons we’re talking about here are Komodo dragons (Varanus komodoensis), the largest living lizards, which can be found on some Indonesian islands and can reach a length of 3 meters. Their size, along with the absence of large mammalian carnivores on the islands, makes them apex predators in their habitat.... Read more »

How often have you accidentally or purposefully spread a rumor through a tweet, status update, or text message? Sometimes you hear or see a piece of information that you’re not totally sure is accurate, but it is so compelling, you pass it on anyway. The epitome of rumor spreading in the 21st century. You would think that with all our followers, friends and all those contacts stored in smart phones, more rumors would get circulated than ever before. That may even be true, but the new discovery in the world of networks and communication is that the stronger the ties you have to the people in your network, the less likely it is that rumors will spread....

One of the discoverers of DNA’s structure, James Watson was never known for his modesty. Now, 60 years after the discovery that earned him, Francis Crick and Maurice Wilkins a Nobel Prize, Watson’s at it again; he’s criticizing cancer researchers worldwide for being too lazy, and relying too much on genetic answers. “The now much-touted genome-based personal cancer therapies may turn out to be much less important tools for future medicine than the newspapers of today lead us to hope,” he says in his latest “manifesto” in Open Biology. At a conference in San Diego, he actually touted the benefits of Metformin, a drug commonly used against diabetes.... Read more »

Hello Julie,My, oh my! What an exciting time it was last week, witnessing Dog Spies' migration to the Scientific American Blog Network. Such a great day for dogs, for science and for YOU! Yah! for this recognition of your fabulous writing achievements, communicating the field of canine science to a broader audience. WELL DONE!As for your question about writing and how I do it, I have to admit I'm 'between systems' currently. By this, I mean that I sometimes map out ideas and plan my writing on paper before hitting the laptop; other times I just let rip straight onto the keyboard. I don't know if I'll ever migrate to a completely paperless system, but I feel that I'm moving in that direction. I still take most of my notes in meetings on paper, which is ridiculous as my handwriting is barely legible, even to me!Thanks also for the link to that piece by Clive Wynne about academic writing - I really enjoyed reading it.META-ANALYSIS You said it. I'm neck-deep in meta-analysis goodness right now and I'd love to tell you more about it. The meta-analysis data set I'm currently involved in compiling is about canine salivary cortisol (that just means cortisol found in dog spit). Cortisol is a hormone (more detail here) regularly used in research concerning animal stress and welfare. I've been interested in canine salivary cortisol for a while now. That's partly because I collected a lot of it (dog spit, that is) from dogs living in home environments and working dog kennels as part of my PhD research; and partly because its really interesting! But my data alone is just one piece of a bigger puzzle. While it's really valuable information (of course it's valuable, it's part of my PhD!), it only offers insight into around 75 dogs from one population of purpose-bred dogs in one geographic area during one two-year period. How do the results of these dogs in my study compare to 'normal' dogs?Well, you see - that's the thing. What is the normal range for salivary cortisol in dogs? We don't really know. What is it?Meta-analysis is a way of evaluating and interpreting the results from research about a particular topic. It adds together the data from different studies, then looks at the compiled data pool to see what patterns and relationships might emerge in the larger body of available information created by the many research projects.Throw another dog in the (data) pool! (source)Why use it?The patterns and groups we might look at within a meta-analysis of salivary cortisol (often used as an indicator of stress/welfare in dog research) are things like: Effects of different environments (do all the results from dogs housed in 'unfamiliar kennel environments' or 'familiar home environments' clump together at different or similar points within the range of values as a whole?); Effects of breed/age (is the range for labradors the same as that for german shepherds? Are all the young dogs in the same place as the old dogs?); Methodological aspects (such as what collection media was used: cotton swabs / synthetic rope / swabs with a saliva stimulant, etc. - does this effect where the cortisol results lie within the whole range?) All this information (and much more!) can be investigated and the information will help to provide further context for the existing studies, while also informing the design and interpretation of future studies. ...

Mindfulness is a technique that encourages people to become more aware of the present moment by paying attention to current sensations, thoughts and feelings in a non-judgemental way. Previous research already demonstrated that mindfulness-based meditation can enhance multitasking behavior, improve skin conditions, and sooth pain.

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?...

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....
