We've all been caught jaywalking. You will NOT see jaywalking during your vacation here, even though it is rather widespread in other world areas.

Fortunately, in a densely populated city such as Seoul, this results in safer streets and fewer traffic accidents.

Austen wrote an epistolary novel called Love and Friendship (sic), a satire of the trend of sensibility in fiction, when she was 14 years old, in 1790. By the age of 18, Austen had made a career out of writing and had experimented with writing drama and longer works.

The US Geological Survey (USGS) studies the invaders using marine lampreys caught in traps. They separate the females and kill them to restrict their reproduction. Before being released back into the Lakes, the males are injected with a sterilant to prevent subsequent progeny. It's unknown why they don't kill the males as well, but it's possible that such attempts would be too swift and disrupt the ecosystem's equilibrium (even if it is currently weighted in favour of the destructive sea lampreys).
