Why Carrots Taste Sweeter In Winter
UCLA’s Liz Roth-Johnson explains why carrots have more sugar when it’s cold outside.
Because plants are immobile, they must develop defense techniques against predators and the severe cold in winter. For example, carrots have developed the physiological response of increasing their sugar content when it’s cold outside. This helps stop ice crystal formations and prevents damage to the carrot’s cells.
Frost can do a lot of damage to a plant cell. It can squeeze and rupture the cells until they are completely demolished. But in some cases, the plant’s defense mechanism means a tastier vegetable for us to eat. When a carrot defends itself from frost, we get the benefit of enjoying sweeter carrots all winter long.

When many individual organisms, like locusts, bacteria, anchovies, or bats, come together and move as one coordinated entity, that’s a swarm. From a handful of birds to billions of insects, swarms can be almost any size. Gigantic swarms can host millions of insects and travel thousands of miles, devastating vegetation and crops. They stay close to each other, but not too close, or they might get eaten by their hungry neighbors.
What all swarms have in common is that there’s no leader. Members of the swarm interact only with their nearest neighbors or through indirect cues. Each individual follows simple rules: Travel in the same direction as those around you, stay close, and avoid collisions. There are many benefits to traveling in a group like this. Small prey may fool predators by assembling into a swarm that looks like a much bigger organism. And congregating in a large group reduces the chance that any single individual will be captured. Moving in the same direction as your neighbors saves energy by sharing the effort of fighting wind or water resistance. It may even be easier to find a mate in a swarm. Swarming can also allow groups of animals to accomplish tasks they couldn’t do individually. When hundreds or millions or organisms follow the same simple rules, sophisticated behavior called swarm intelligence may arise.
