3:16 PM | Feb 2015: Damien Farine, penguins who can't taste, and shiny tree swallows
This month, I find out that penguins can’t tell the difference between savoury and sweet. I also chat with Sonia Van Wijk from The Université de Sherbrooke in Quebec, Canada, about what makes a male tree swallow attractive to a female who's on the look-out for more than one partner. And in the Scientific spark, I talk to social network whizz Damien Farine, from the University of Oxford, about his path into science. Download the MP3Adelie penguins […]

Methylation and cell type differences Watch for other articles from Nugent et al., that attest to the obvious involvement of epigenetic effects on RNA-mediated cell type differentiation. Eventually, these researchers will need to differentiate cause and effect that has been...Read more
3:32 PM | Gut Feelings
This boy may be influencing who he will marry when he grows up. Photo by Orrling at Wikimedia Commons.Animals (including humans) are swarming with microorganisms both on and in our bodies. Humans harbor so many different microorganisms that we have over 150 times more microbial genes than mammalian genes, and it is reasonable to suspect that this scenario is similar for most animals. But before you run to soak in a tub of hand sanitizer, you should realize that many of these microorganisms are […]

4:00 AM | Pond Dwellers (Friday Five)
I’ve been spending a lot of time photographing aquatic insects recently.  I’ve been very busy at work, so I find it relaxing to sit and watch my little tank full of insects in the evenings, observing their behaviors and photographing them.  Next week I’ll share another developmental series like the snail series I posted last week, […]

4:00 PM | Music to a Cat’s Ears
 A recently published study has shown that cats are attracted to music that was specifically designed for them. This is important work, given all the claims that are made about effect of music “designed for” dogs and cats. Although there are several interesting studies this issue, the studies have traditionally compared different types of musical […]

2:08 AM | A Spring in His Step (Well-Nigh Wordless Wednesday)
Yesterday was an absolutely perfect day outside and I spent a half hour after work looking for cool bugs in the pond to photograph.  I found a great diversity of pond critters, but one of the things I was most excited to try my hand at photographically were the springtails I found hopping about on the […]

8:14 PM | All About Dog Poop
Because it isn’t necessarily a fun topic, I thought I’d start off with my favorite story about dog poop. Imagine being at a sit-down lunch at two-day seminar I was giving on canine behavior and training. Picture a large room, with 150 people or so, sitting at round tables covered in white table cloths, the […]

2:34 PM | Komodo Dragons: Their Bite is Worse than Their Bark
By Shelly Sonsalla Komodo Dragon. Image by Arturo de Frias Marques on Wikimedia. Komodo dragons are the world’s largest living lizard and can be found only on select islands in the Indonesian archipelago. These massive lizards can grow to be 10 feet in length and up to 150 pounds! Their natural prey includes wild boars, deer, and water buffalo—animals which may outweigh them by several hundred pounds. So how does a lizard, even such a large one, manage to take down prey so […]

10:22 PM | Sept 2013: Amy Cuddy and power posing, honeyguides, and bower bird cognition
Amy Cuddy joins me in this month's Beepcast, telling me what ignited her interest in how people judge and influence each other. I explore the darker side of bird behaviour, looking at the sneaky tactics African honeyguides use to trick other birds into raising their young. In the second of my interviews from the Behavior 2013 conference, I speak to Jess Isden of Exeter University who explains what female bowerbirds look for in a male’s fancy display. Download the […]

10:19 PM | Dec 2013: Steve Jones, slime mold, and spiders that mimic ants
This month, we leave backbones behind, for an invertebrate and protist special. I speak to Chris Reid from the the New Jersey Institute of Technology in Newark, USA, about an ancient single cell animal that looks like a glob of luminous yellow gunge, that doesn't have a brain but may be smarter than human beings. I find out about a double deception in the animal kingdom: how an ant-mimicking spider sends misleading visual and chemical cues to different predators. And, in the scientific spark I […]
10:18 PM | Jan 2014: Lesley Morrell, prairie dogs, and stinky parrots
This month, I speak to Milla Mihailova from Deakin University in Australia, who tells me about parrots with a particularly pungent stench. I get up close and personal with some black tailed prairie dogs, to find out why they can’t help following the leader. And, in the Scientific Spark I ask Lesley Morrell (@biosciencemum), from the University of Hull what made her want to be a biologist, and how she came to work on why animals live in groups, rather than enjoying the single life.Download […]
10:18 PM | Feb 2014: Kirsty MacLeod and meerkats, birds and airplanes, and New Zealand conservation with James Russell

The social lives of animals is this month's theme. I talk to Damien Farine from the Edward Grey Institute at Oxford University, who tells me how weaver birds decide how many house mates they want to live with.
