New CME Brief Report: Optimizing Treatment for Insomnia

Dr Krystal describes a new paradigm for managing insomnia in which clinicians can select interventions that best target the sleep problem of each patient. The result is an improved risk-benefit ratio.

Milhões de pessoas migraram para cidades próximas, para centros maiores ou para outras regiões

(crédito: MAURO PIMENTEL/AFP)

Em meados do século 20, a agricultura passou por mecanização e, com isso, liberou mão de obra rural em direção aos centros urbanos no Brasil. Milhões de pessoas migraram para cidades próximas, para centros maiores ou para outras regiões. Em tese, no meio urbano, os migrantes encontrariam postos de trabalho que exigissem baixa qualificação técnica. Com isso, acelera-se o processo de urbanização. A caminhada para os grandes aglomerados urbanos aconteceu ao redor do mundo e não poderia deixar de acontecer no Brasil. Nessa época, portanto, o país deixou de ser agrário para se tornar urbano. Costuma-se referir que as cidades intermediárias receberam população por oferecerem equipamentos e serviços, tornando-se atrativas aos imigrantes. Essas cidades intermediárias não chegam a competir ou rivalizar com as/.../

What is the smallest particle in the universe? (What about the largest?)

By JoAnna Wendel - Live Science Contributor 17 days ago

The smallest weighs way less than an electron.

The universe is a big place, but it's made out of small pieces. The periodic table includes elements such as oxygen, carbon and other building blocks that make up stars, cats or cups of coffee. But since the turn of the 20th century, scientists have been thinking about and finding smaller and smaller fundamental particles — those tinier than atoms that fill up the universe. So which of these fundamental particles is the smallest? And, conversely, which is the largest?

Don Lincoln, a senior scientist at Fermi National Accelerator Laboratory (Fermilab), near Chicago, is one of the scientists trying to answer this question. At Fermilab, scientists use a particle accelerator to smash individual particles together and look at the debris — or possible new fundamental particles — that come out. Lincoln said there are two ways to measure the size of particles: investigating their mass and measuring their physical size, like calculating the diameter of a ball./.../
