The loathsome, lethal mosquito
AdultsAnimalsScienceEnvironmentWildlifeHealthBiologyEveryone hates mosquitos. Besides the annoying buzzing and biting, mosquito-borne diseases like malaria kill over a million people each year (plus horses, dogs and cats). And over the past 100 million years, they've gotten good at their job -- sucking up to three times their weight in blood, totally undetected. So shouldn't we just get rid of them? Rose Eveleth shares why scientists aren't sure.
The Most Amazing Thing About Trees
AdultsEcologyNatureScienceEnvironmentBiologyTrees create immense negative pressures of 10's of atmospheres by evaporating water from nanoscale pores, sucking water up 100m in a state where it should be boiling but can't because the perfect xylem tubes contain no air bubbles, just so that most of it can evaporate in the process of absorbing a couple molecules of carbon dioxide. Now I didn't mention the cohesion of water (that it sticks to itself well) but this is implicit in the description of negative pressure, strong surface tension etc.
Dead stuff: The secret ingredient in our food chain
AdultsEcologyFoodScienceBiologyEnvironmentNatureWhen you picture the lowest levels of the food chain, you might imagine herbivores happily munching on lush, living green plants. But this idyllic image leaves out a huge (and slightly less appetizing) source of nourishment: dead stuff. John C. Moore details the "brown food chain," explaining how such unlikely delicacies as pond scum and animal poop contribute enormous amounts of energy to our ecosystems.

How we found the giant squid
AdultsAnimalsWorldEnvironmentOceanWildlifeBiologyHumankind has been looking for the giant squid (Architeuthis) since we first started taking pictures underwater.
