Evolution's recipe book: How 'copy paste' errors cooked up the animal kingdom

A series of whole genome and gene duplication events that go back hundreds of millions of years have laid the foundations for tissue-specific gene expression, according to a new study.

Как изобрели письменность? Часть 1: от рисунков, токенов и прото-письма к клинописи

Наш современный мир переполнен, буквально затоплен текстами на разных языках, написанными разными системами письма. Они окружают нас везде, в оффлайне и тем более в онлайне. Человек XXI века ежедневно прочитывает столько информации, сколько образованные люди древности порой читали за всю жизнь. Обитателям сети очень трудно представить то, как жило подавляющее большинство человечества в прошлые эпохи — когда и текстов, и умеющих их читать было несопоставимо меньше. А большую часть истории...

Suddenly, Travis Touchdown's world had broken free of the TV, and I was thrilled. Oxenfree developer Night School's brisk new... Read more

Practice may do more than make perfect. Researchers found that extensive training physically reorganizes the brain, allowing learned tasks to bypass the prefrontal cortex and run through specialized circuits instead. By freeing the brain's "thinking" center, people became better at performing another task at the same time, challenging the long-held idea that humans only switch rapidly between tasks rather than truly multitask.
