Hey Julie, I absolutely LOVE Project: Play with your Dog study and how the Horowitz Dog Cognition Lab are crowd sourcing using citizen science! I don't think a better way of contributing to scientific understanding can possibly exist! I look forward to hearing updates about how the research goes. I will certainly participate - next time we head to the river to play, we'll take our camera to get some video! So you might have noticed the silly season of festivity has landed upon us...

There is a companion article exploring the issue from the perspective of environmental monitoring over at ArkFab.

My first impression upon hearing the hypothesis that Dickinsonia (Fig. 1) may be a lichen was that it does not look like any lichen I’ve ever seen. To be fair, the more normal interpretation that it is a marine animal, a segmented worm, sparks the same response…it does not look like any animal I’ve ever seen or heard of. What it actually resembles is a giant diatom, but that is pretty silly. This uncertainty is exactly what has been nagging paleontologists since the 1940’s….what are th........ Read more »

Gold is not considered a dietary micronutrient, and is the one of the most inert metals. But this is not to say it has no role in living systems; in fact, this metal is a veritable gold mine of biology. Recent studies have shown that at least one bacterium uses gold in the active site of a NADH oxidase enzyme, and several microorganisms can accumulate gold and precipitate out pure flakes of gold. Saprobic fungi are now used to survey the gold in an area and point the way to new gold mines. Most ........ Read more »

Covering yourself with garbage is a great way to look less delicious to predators. More than a hundred million years ago, one insect species took this strategy to the extreme by growing a kind of giant trash can on its back. Scientists could identify the new species thanks to a remarkable specimen that was preserved—along with an informative topping of trash—in amber.
The insect that kindly died in a blob of tree resin in early-Cretaceous Spain was a young green lacewing. Modern-day gree........ Read more »

While scientists like to bandy origin of life theories around, they seldom make the connection to astrobiological research.

If shots of whiskey make you dizzy, shots of laser stun. NASA stunned me this week, when I discovered that they provide millions such shots of Greenland from which to construct detailed images of the landscape. The shots are free, no age-limit. This is better than the usual remote sensing or photography of “just” brightness. The laser gives us height, and not just the perception of it by shadows and fake angles of illumination, but hard and direct measurements of, well, height above sea leve........ Read more »

What would happen if the Earth’s axis suddenly tilted by 50 degrees or more? It may sound like the plot of a bad science fiction movie, but scientists say it’s not an academic question — geological records show such shifts have happened several times throughout the planet’s history, with dramatic effects on climate and sea level.
Harvard researchers are now answering one of the key questions related to such shifts: Once its axis tilts, how does the Earth “know&rd........ Read more »

It was crabnapping for a just cause. But the crustaceans that found themselves suddenly plucked from their burrows, stuffed into opaque sacks, and carried off through the forest couldn't know that. When the scientists freed their captives, they waited to see whether the crabs would find their way home or be stranded forever. They'd be watching—from space.
The best way to find out exactly where and how far an animal travels is to tag it with a GPS tracker. But if you're interested in invert........ Read more »

A number of times over the past one billion years, the Earth's surface has "wandered" relative to its rotational axis – before returning to its original position. Now, a team of geophysicists from the US and Canada says it has developed a theory that explains this curious phenomenon of "oscillatory true polar wander". Understanding the mechanics behind polar wander is crucial, as a shift could tip the Earth over by as far as 50° over a period of 10–100 mi........ Read more »
