How Crypto Disappeared Into Thin Air
Carnage in the cryptocurrency market is nothing new.

Genetic predictability steadily erodes during evolution, new study shows
A critical goal in genetics and evolution is predicting the effects of mutations that may happen in the future and inferring the effects of those that happened in the past. To make these predictions, scientists generally assume that a mutation's effects tested in the present apply to past and future versions of the same gene.

Study finds why baby leatherback marine turtles can't 'see the sea'
When sea turtle hatchlings emerge from their nests, typically at night, they crawl toward the ocean in what is known as "seafinding." They have to discriminate between the brighter seaward versus a dimmer landward horizon and then move toward the source of the light. That difference in radiance between opposing horizons enables them to find the ocean even when the uneven surface of the beach precl
