If you had to sum up the past 40 years of research on the mind, you could do worse than to call it the Rise of the Zombies.

We like to see ourselves as being completely conscious of our thought processes, of how we feel, of the decisions we make and our reasons for making them. When we act, it is our conscious selves doing the acting. But starting in the late 1960s, psychologists and neurologists began to find evidence that our self-aware part is not always in charge. Researchers discovered that we are deeply influenced by perceptions, thoughts, feelings, and desires about which we have no awareness. Their research raised the disturbing possibility that much of what we think and do is thought and done by an unconscious part of the brain—an inner zombie.

“I’m happy to send you my very own science tattoo — a buckyball net. I’ve always been fascinated by carbon and its presence on our planet — but I didn’t want to choose an ordinary representation of carbon for my…uh…lifetime ink commitment. Behold the carbon 60 molecule, which just happens to fit my idea and look ridiculously cool, especially when “unfolded.” I initially wanted the design to be small and discreet, but my tattoo artist thought it was such a cool design that he insisted I get it bigger. I’m happy I took his advice.”

New Zealand is home to 2,065 native plants found nowhere else on Earth. They range from magnificent towering kauri trees to tiny flowers that form tightly packed mounds called vegetable sheep.

When Europeans began arriving in New Zealand, they brought with them alien plants–crops, garden plants and stowaway weeds. Today, 22,000 non-native plants grow in New Zealand. Most of them can survive only with the loving care of gardeners and farmers. But 2,069 have become naturalized: they have spread out across the islands on their own. There are more naturalized invasive plant species in New Zealand than native species.

There’s a very cool paper in the latest issue of Science that pinpoints a particular chunk of DNA that may have played a role in the evolution of a human-like hand from the hands of our primate ancestors. Not Exactly Rocket Science has the details. For some reason, a number of articles on the paper are using the hook that this segment of DNA was once dissed as junk. “A patch of DNA once regarded as ‘junk’ may hold the key to upright walking and opposable thumbs,” according to Wired. These reports seem to be following the language from the original press release.

The “Wow! Junk DNA is not junk after all” news hook is a tempting one, but it needs to be resisted. At the very least, science writers need to recall some history.

I can’t help finding the Irish elk wonderfully ridiculous. The reaction probably has something to do with the fact that we are all familiar today with deer, moose and other animals that look for the most part like the Irish elk, except for that extravagant rack. Irish elk grew the biggest antlers ever recorded, stretching over ten feet across and weighing about 90 pounds. Of course, for the people who lived alongside the Irish elk in Europe and Asia before its extinction 7000 years ago, it probably didn’t seem terribly ridiculous at all–no more ridiculous than an orangutan or a river dolphin look to us today.
