The Late Jurassic was the heyday of sauropod dinosaurs in prehistoric North America. Apatosaurus, Diplodocus, Barosaurus and Brachiosaurus were among the titans found in the 156- to 146-million-year-old Morrison Formation. But after this slice of geologic time, North American sauropods all but disappear.
There have been just a few discoveries of Cretaceous sauropods in North America. [...]... Read more »

For a blog called Reaction Norm, it’s about time I wrote something about gene-environment interactions. First, the term itself. It is trivial to say that genes and the environment “interact” since broadly speaking we know that all organisms and therefore all phenotypic traits at some level depend on the environment and at some level depend [...]...

The toll is horrendous. Each year, some 100 people – and 50 elephants – are killed in farmer-pachyderm clashes around some of Sri Lanka’s lush rice paddies. Now, two researchers are wondering if a rice “deodorant” could reduce the carnage.

Considering the many diverse environments that bacteria live in, it isn't surprising that they have many different ways of moving. Swimming, swarming, gliding, twitching, floating: these aren't just different ways of describing the same movement, these are specifically different mechanisms that bacteria use to manouvre themselves across surfaces, through liquids and towards their preferred environments and food sources.Most bacteria use their flagella to swim. These are long proteinous threads w........ Read more »

Studies suggest that chronic fatigue may not only have the power to change a person’s personality but that certain personality traits may also put a person at higher risk of developing chronic fatigue.

It’s a little embarrassing.
Despite being about as familiar and as commonplace as you can get, we still don’t have a clear understanding of why humans yawn.
We know we start yawning early. We know we yawn when we’re tired. We know we yawn when we’re bored. And we know that yawning can sometimes be contagious. But the function, the why, has been elusive.
A new paper by Giganti and Zilli ties together a couple of yawning’s features: that the amount people yawn varies throughout the d........ Read more »

With the help of five to eight 'confederates' (research assistants posing as naive participants), Solomon Asch in the 1950s found that when it came to making public judgments about the relative lengths of lines, some people were willing to agree with a majority view that was clearly wrong.
Asch's finding was hugely influential, but a key criticism has been his use of confederates who pretended to believe unanimously that a line was a different length than it really was. They might well have beh........ Read more »

When I sit down to use my computer, the first thing I usually do is double-click the icon that opens up an internet browser. I do this so often, that even when I need to use the computer for purposes other than internet-browsing, I mindlessly open up the internet browser anyway.
