This tube worm’s glowing slime may help sustain its own shine
Snot oozed by a marine tube worm can glow for up to 3 full days. The secret of how this works might lead to long-lasting lights that glow on and on.

Rock Candy Science 2: No such thing as too much sugar
Making rock candy at home takes a lot more sugar than you might think. Why? This experiment will show you why.

Banana plant extract can slow how fast ice cream melts
Food scientists now show that adding these tiny plant particles to ice cream may delay the rate at which this treat melts into a soupy mess.

Scientists Say: Catalyst
Sometimes a chemical reaction can take a while. If speed is needed, a catalyst can help.

Trees can make summer ozone levels much worse
The greenery can release chemicals into the air that react with combustion pollutants to make ozone. And trees release more of those chemicals where it gets really hot, a new study finds.

Ancient Arctic ‘gas’ melt triggered enormous seafloor explosions
Methane explosions 12,000 years ago left huge craters in bedrock on the Arctic seafloor. Scientists worry more could be on the way today as Earth’s ice sheets melt.

How Earth got its moon
How did our moon form? Scientists are still debating the answer. It may be the result of some one big impact with Earth — or perhaps many small ones.

Here’s how hot water might freeze faster than cold
There’s a new explanation for how hot water freezes faster than cold water. But not everyone agrees it’s right, or that the effect can happen at all.

Sunlight + gold = steaming water (no boiling needed)
Nano-gold is the new black, at least when it comes to absorbing heat. When tiny gold particles get together, they become energy super-absorbers — turning them black.

Carbon dioxide could explain how geysers spout
A new study overturns 150 years of thinking about Yellowstone’s geysers. Carbon dioxide, not just hot water, may be driving those spectacular eruptions.

Cool Jobs: Big future for super small science
Scientists using nanotechnology grow super-small but very useful tubes with walls no more than a few carbon atoms thick. Find out why as we meet three scientists behind this huge new movement in nanoscience.
