Amanda Palmer Reads Polish Nobel Laureate Wislawa Szymborska’s Poem “Life While-You-Wait”*by Maria Popova* *Consolation for those moments when you feel “ill-prepared for the privilege of living.”* One spring evening not too long ago, I joined the wonderful Amanda Palmer on a small and friendly stage at Chicago’s Old Town School of Folk Music and we read some Polish poetry together from *Map: Collected and Last Poems*(*public library*) — the work of Nobel laureate*Wislawa Szymborska* (July 2, 1923–February 1, 2012), for whom we share deep affection and admiration. When Szymborska was a... mais »

Swedish scientists create an artificial neuron that mimicks an organic one Could remotely stimulate neurons based on specific chemical signals received from different parts of the body, or doctors could artificially bridge damaged nerve cells and restore neural functions June 29, 2015 Chemical-to-electrical-to-chemical signal transmission. A conventional neuron (upper panel) senses chemical signals (orange circles), which trigger an electrical pulse of membrane depolarization (action potential) along the axon, causing chemical release at the axon terminals (blue circles).

Walking in nature lowers risk of depression, scientists find in MRI study July 1, 2015 [image: rumination to sgPFC-ft] Urbanization is associated with increased levels of mental illness A new study has found quantifiable evidence that supports the common-sense idea that walking in nature could lower your risk of depression. The study, published in Proceedings of the National Academy of Science, found that people who walked for 90 minutes in a natural area, as opposed to participants who walked in a high-traffic urban setting (El Camino … more…

stem cells communication

Long-term memories in mice are maintained by prion-like proteinsJuly 3, 2015 *Columbia University Medical Center | Long-term Memories Are Maintained by Prion-like Proteins* The molecules that maintain long-term memories in mice are a normal version of prion* proteins and work the same way as mechanisms in prions that cause mad cow disease, Creutzfeld-Jakob disease in humans, and other degenerative brain diseases. That’s the conclusion of research from the lab of Nobel-winning neuroscientist Eric Kandel, MD, of Columbia University Medical Center (CUMC). When long-term memories are cre... mais »

End of the Universe

Aloyzio AchuttiemAMICOR - Há 41 minutos
This is how the universe will end: not with a bang but a rip July 3, 2015 [image: This is a time line of life of the universe that ends in a Big Rip. (credit: Jeremy Teaford, Vanderbilt University)] First the galaxies are destroyed. Then the solar system breaks apart and the Earth explodes. Finally, the atoms themselves are ripped apart. Vanderbilt University mathematicians have come up with a new theory of “cosmological viscosity” (how sticky the universe is) that challenges current theories. For decades, cosmologists have had trouble reconciling the classic notion of viscosity base... mais »

*A paretir de mensagem do AMICOR Jorge Rocha Gomes: * *Eu também não sabia que o Ruy havia falecido. Tivemos vários momentos comuns em nossa vida. Ele da Cardiologia também se interessou pela Epidemiologa. Um momento especialmente gostaria de citar, inclusive por que foi um ponto de partida para muito de minha trajetória posterior: ele participou daquele estudo sobre mortalidade em 12 cidades das Américas e da Inglaterra que serviu de base para a constatação pela Assembléia Mundial da Saúde de que países em desenvolvimento tinham dupla carga: além das peculiares ao subdesenvolvimen... mais »
