Jared Diamond's account of the collapse of Easter Island society is well known by now — how the Islanders decimated their ecosystem and drove themselves to the brink of starvation by using up the island's natural resources at a furious rate. But that's not the only possible explanation for how Easter Island lost its tree cover and ended up with a much-reduced population. In fact, some anthropologists say there's not really any hard evidence that the Islanders were practicing slash-and-burn agriculture, clearing the land with fire.
Instead, this other theory blames the little creature pictured above — the Polynesian rat, an invasive species that stowed away on canoes and chewed its way through the roots, sprouts, and seeds of Easter Island's trees. Instead of willfully destroying themselves, this scenario has the islanders desperately adapting to a quickly changing environment. It's not that the changes had nothing to do with people — the rats got there with human help, after all — but the angle of the story changes somewhat, becoming less about the destructive aspects of human nature and more about the lengths humans will go to in order to survive.

Despite Trump’s denial of climate change the the ghastly attacks on climate science and mitigation in the new proposed budget, the Carbon Bubble — which overprices hydrocarbons and the industries that rely on them, as though we’ll be burning all of them with impunity — is about to pop.
South American polka dot tree frogs are pretty cool, but Julián Faivovich and Carlos Taboada found out they are even cooler when an ultraviolet flashlight is trained on them. They fluoresce. Many animals can see beyond the spectrum visible to humans, and these frogs adapted with this trait. From the abstract: Fluorescence, the absorption of […]
A small (51 men aged 24 +/- 3 years) study published in Neuron tasked experimental subjects with practicing the ancient Greek mnemonic technique of “memory palaces” and then scanned their brains with functional magnetic resonance imaging, comparing the scans to scans from competitive “memory athletes” and also measuring their performance on memorization tasks.
The Lightning port has thus far resisted the cruel fate that befell the headphone jack, and despite rumors that it may be disappearing come iPhone 8, for the present and foreseeable future, Lightning cables are a hot commodity for iPhone users. As such, we must make do in this strange time in which long, glorified […]
All the filters in the world won’t save your smartphone pics from a shaky hand. To really step up your mobile photography game, you’ll need some kind of mount to hold it steady. You could buy a smartphone attachment for a conventional camera tripod, but who wants to carry that kind of gear everywhere they […]
The forced transition from analog to digital TV signals was probably met with relative indifference from people with Netflix subscriptions and the “I don’t even own a TV” snoots. But anyone living in the vast swaths of the country that don’t have guaranteed high-speed internet, broadcast TV is a perfectly valid (and 100% free) way […]
