Beauty
The Science of Beauty*by Maria Popova* *“Attitudes toward beauty are entwined with our deepest conflicts surrounding flesh and spirit.”* *“That is the best part of beauty, which a picture cannot express,”* Francis Bacon observed in his essay on the subject. And yet for as far back as humanity can peer into the past, we’ve attempted again and again to capture and define beauty. For Indian philosopher Tagore, beauty was the Truth of eternity. For Richard Feynman, it was the mesmerism of complexity. For E. B. White, it was the power of simplicity. For the influential early art theorist ... mais »
Bad memories
Repairing bad memoriesJuly 1, 2013 (Credit: iStockphoto) Recent research has shown that memories are not unchanging physical traces in the brain. Instead, they are malleable constructs that may be rebuilt every time they are recalled, *MIT Technology Review* reports. Doctors (and psychotherapists) might be able to use this knowledge to help patients block the fearful emotions they experience when recalling a traumatic event, converting chronic sources of debilitating anxiety into benign trips down memory lane. Research argues that we can alter the emotional impact of a memory by addin... mais »

In our Milky Way galaxy alone, 60 billion planets may be orbiting red dwarf stars in …more…

The release of seven ultrasharp, large-field images from the instrument’s first science observations demonstrate its remarkable discovery potential./..../
Exercise and Anxiety
Exercise reorganizes the brain to reduce stress and anxietyJuly 5, 2013 [image: more-new-neurons-in-runners_400] A research team based at Princeton University found that physical activity reorganizes the brain so that its response to stress is reduced and anxiety is less likely to interfere with normal brain function. Running produced a large increase in the number of new neurons in the hippocampus — a brain region shown to regulate anxiety — of a mouse that ran for six weeks (above). The brown cells are new neurons, which are more numerous in active mice than sedentary mice, and the ... mais »

*Prezados colaboradores da luta diária e, necessariamente, crescente contra o tabaco e o tabagismo:* Esta notícia sobre a criação do "dia do fumicultor" chega a parecer surrealista, mas não surpreendente, pois isto acontece quando se trata de vultosas quantias envolvidas em negócios de um setor, e indeclaráveis interesses eleitoreiros de políticos que se entregam mercenariamente às necessidades corporativas destas empresas bilionárias, mesmo que isto represente graves prejuízos para a saúde e a vida da população. Pelo noticiário, tanto o Deputado Heitor Schuch, quanto o Governador... mais »
