3:10 AM | Friday 5 (on Saturday): Insect Haikus for the End of Summer
For some reason, I was feeling poetic today.  I started making up poems in my head on my way home from work and made excellent progress on a multi-stanza educational poem about dragonflies I might share with you sometime.  But I also came up with a series of haikus, inspired by the changing seasons and some […]

8:26 PM | Sea Lions’ Whiskers are Sensitive, Dynamic
You know the classic circus trick of a sea lion balancing a ball on its nose? It turns out whiskers are the key to making it work. Researchers filmed sea lions to investigate whether they use whisker control to coordinate ball balancing. See what they found in my latest Zoologic post: Sensitive Sea Lion Whiskers Get the Job Done .

My ‘friend’ Adam Hayward is a postdoctoral researcher at the University of Edinburgh. His research involves the study of ageing, for which he typically uses detailed life history records from long-term studies of mammals (including sheep, elephants and humans). This means he does not have to perform experiments, instead waiting patiently until the data thwacks […]
