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.

EarthAncient 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.

ChemistryHere’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.

PhysicsSunlight + 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.
