So, apparently, some people think the snow that fell on Atlanta wasn't actually snow, but some kind of synthetic material dumped on the town by the government in order to cause chaos. The proof: The Atlanta snow won't melt and it turns black when you hold a lighter to it.
Except, that, well, the same stuff will happen to snow when you hold a lighter to it anywhere. In this video, Phil Plait demonstrates the effect in Colorado and explains what's actually going on. The key is that the snow really is melting, you just can't see it. Snow absorbs liquid. Plait has a really good analogy here with snowcones. You pour the syrup on, and the shaved ice absorbs it. Same thing with the snow that's turning to water in the heated snowball. Up to a certain point, the rest of the snow will absorb that water. Heat the ball long enough, though, and you will, eventually, get a puddle. The conspiracy videos just stop well short of that point.
And the burn marks? That's just soot from imperfectly burned butane from the flame itself.
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.
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 […]
When Apple revealed the new MacBook in 2016, one of the biggest issues raised with the notebook’s new design (aside from ire over the slew of new adapters you’d inevitably have to buy) was the removal of one of its most beloved proprietary features, the magnetic charging cable. Thankfully, third-party peripheral makers have taken up […]
