3:40 AM | More Insect Haikus (Friday 5)
The insect activity was a bit sparse this week, in spite of some lovely warm days and some exciting things that happened.  Because there are so few insects to report, I’m going to share some haikus of recent insect and insect-related observations I’ve made over the past few weeks.  Hope you enjoy them! Ode to […]

4:08 AM | Mute points: most are afraid to mention them
In discussion of anthropic theory and the fact that fundamental physical constraints underlie our life-enabling universe, Andrew Jones wrote: “Pathogenicity of E. coli 0157 has nothing to do with its temperature stability.” Like others who are biologically uninformed, Jones defies...Read more

7:17 PM | New on Zoologic: Can Spiders Count?
Golden orb-web spiders are sit and wait hunters that accumulate prey larders on their webs. If prey items are removed from their webs, golden orb-web spiders search for them. They search longer when they have lost more prey items as well as when they have lost larger prey items. A new experiment looked at whether these spiders have a sense of numerosity: the ability to track the number of prey items in their larders. Read my latest Zoologic post: Can Spiders Count?

6:41 PM | The Beaten Angels of our Nature. Is Steven Pinker right?
Could we affirm that we have become more peaceful than people from some centuries ago? Some renowned scientists say that we have become indeed more peaceable and they have some apparently good explanations for their statements. The evolutionary psychologist Steven Pinker, a notorious scientist, one of the most influential contemporary thinkers, claims that human aggression […] The post The Beaten Angels of our Nature.

8:19 PM | Making the Medicine Go Down: Giving a Dog a Pill
Can you give your dog a pill? More to the point, can you give your dog a pill three times a day without any stress on you or your pooch? A recent online discussion reminded me how difficult it can be to get some dogs to take their medicine, and I thought it might be […]

5:18 PM | Why You Can’t Hibernate the Winter Away
You open your eyes, slap the alarm, and pull the covers a little tighter around your shoulders. It’s still dark outside and you dread the moment that you step out from under the warm comforter and the cold sucks your breath out. Can’t you just hibernate and sleep the winter away?A dormouse in his snuggly hibernation state. Image by Krysztof Dreszer at Wikimedia. Actually, no. Hibernation and sleep are two completely different physiological processes (shown by studies of brain […]

5:12 AM | 2015: Puppy New Year! Get some science into your dog
2015 is a bright and shiny new year for canine science! But first, this face:After being a dog-less household for eight months (you might remember we sadly farewelled Elke in 2013 and gut-wrenchingly, also old man Caleb, in the first half of 2014) we welcomed a new member to the family at the end of 2014. Those paws. Not photoshopped.If I'm honest with you, I'd been stalking PetRescue quietly for a month or so, not really sure if the time was right, but also open to being inspired to […]

3:03 PM | New on BrainFacts: Recovering from Spinal Cord Injuries
Every year, between 250,000 and 500,000 people around the world suffer a spinal cord injury, leaving many to face a lifetime of permanent, debilitating symptoms. For years, there was little hope for treatment options. Now scientists are exploring new ways to preserve and rewire nerve tissue and restore function, offering hope for recovery in the future.

3:41 PM | Journal Club: Birds pick nest materials with camouflage in mind
SUMMARY: A recent study by a research team in Scotland reveals that birds intentionally choose colour-matching materials to camouflage their nests thereby reducing predation risk. The old saying, “Don’t put all your eggs into one basket” belies the very thing that many bird species must do. For this reason, predation is a major cause of loss of eggs, nestlings and the brooding hen, especially for birds that build open-cup nests. So how do birds protect their nests from […]

3:24 PM | Collective Personality and Our Environment
We are all familiar with the concept of the personality of an individual. We are less familiar with group- or collective personalities (although most teachers can tell you at length about the personalities of each of their classes). The concept is the same: whereas an individual personality relates to an individual’s consistent behaviors across time and contexts, a collective personality relates to a group’s consistent behaviors across time and contexts. Collective personalities can […]
