Chick and Tilda, its mother (photo © and courtesy of Hannele Luhtasela-El Showk)It’s probably not a surprise that humans aren’t the only animals with a sense of numbers. While they’re probably not actually counting, a variety of species seem to be able to tell the number of objects in a group; they can distinguish between groups with greater or fewer objects and react with surprise when the number changes unexpectedly. However, a recent study suggests that this numerical understanding may go deeper than we’ve previously thought. Continue reading →

Book review: We Are Our Brains

'We Are Our Brains' by Dick SwaabI have mixed feelings about We Are Our Brains. The author, Dick Swaab, is a professor of neurobiology at Amsterdam University with decades of research experience and many awards to his name, so the book is full of fascinating and intriguing information. Unfortunately, I felt like the delivery was somewhat lacking, leaving me with more questions and wanting more information. That’s not inherently a bad thing, but I feel like the book could have done a much better job of handling some of the inevitable questions and challenges it raises — it could benefit from engaging in dialogue with the reader rather than simply making assertions.

Old woman or young lady?Humans have an exquisite sense of vision. It’s the primary sense for most of us and our making way of interacting with the world around us.  We process the massive amount of visual data generated by sight using trillions of interconnections between billions of neurons spread across half our cerebral cortex.  Despite this, our visual system falls prey to illusions, constructing ambiguous interpretations and objects that can’t or don’t exist.  How do these illusions work and why do they succeed in fooling us even when we know about them?

How are humans like ants?

Last year, I wrote about how some ants can find their way home after finding food.  They have the remarkable ability to account for all the twists and turns they made while foraging and calculate a direct path leading straight back to their nest.  A reader emailed to ask if I thought humans would ever be able to do something similar or to achieve the level of co-ordination shown by ants.  This post is based on my reply, where I pointed out several things that humans are amazingly good at doing  — in fact, we do them so well and with such ease that you might be surprised by how difficult they actually are!  I’ve spent a lot of time on Inspiring Science talking about behaviours and abilities which show that other animals aren’t just simple automata because I think it’s important to make the point that although humans are unique, we aren’t special; we’re just another species with our own particular tricks for surviving in this world.  I’ll take a different tack in this post and talk about some of the ways we stand out!

Rats with (not quite) telepathy

BeermanTen years ago,  Professor Miguel Nicolelis and his team at Duke University made history.  They implanted electrodes — sensors — into a monkey’s brain and trained her to control a robotic arm with her thoughts. That may sound like the stuff of science-fiction, but his latest work is even more incredible.  In a paper recently published in Scientific Reports, Professor Nicolelis and his team used similar technology to enable a pair of rats to communicate — one brain to another — even when they were a continent apart.  If you’ve read some of the news coverage of this story, you may have gotten the idea that it’s some kind of telepathy, mind control or mind meld. It’s not, but the truth, though more down-to-earth, is no less exciting. Continue reading →

January has been a busy month.  In addition to writing here, I worked on some websites for my family and submitted entries to a couple of science writing competitions for the first time!  I’ve also optimistically nominated Inspiring Science for the annual “Bloggies” awards; if you think it deserves a chance, why not head on over and add your voice? I’ve really enjoyed working on this blog for the past year and I’m looking forward to writing being an even bigger part of my life in 2013!  Anyway, here’s another batch of tidbits I found during my wanderings.  As always, feel free to add more links in the comments.
