Reading List of the 14 Best Books of 2014

Aloyzio AchuttiemAMICOR - Há 9 segundos
The Definitive Reading List of the 14 Best Books of 2014 Overall*By: Maria Popova* *From the origin of the universe to the unusual stories behind people’s tattoos, by way of secular spirituality, the hummingbird effect, and Werner Herzog.* I consider my annual best-of reading lists a kind of Old Year’s resolutions in reverse — unlike traditional resolutions, which lay out an aspirational list of priorities for the new year, these represent a look back at the books that proved themselves most worth prioritizing over the setting year. After such reverse-resolution reading lists for the... mais »

Primo Emil Achutti Bered

Aloyzio AchuttiemAMICOR EXTENSION - Há 24 minutos
Com minhas irmãs (Lia Maria e Maria Helena) visitamos na tarde de ontem nosso primo e tivemos momentos muito agradáveis com a família dele (Rosinha, sua esposa, e três de suas filhas). Registramos o encontro com uma foto. Ele, e seu neto Bruno, planejaram e executaram nosso novo consultório (há 3 anos) no 10 andar do Prime Offices, junto ao Praia de Belas Shopping. Um irmão dele, Walter (mais moço) fez o mesmo há 45 anos atrás, no centro da cidade, onde Valderês e eu atendemos nossos clientes durante 41 anos.

Restoring Memories

It might be possible to restore lost memories Memories not stored in synapses, neurobiologist finds December 22, 2014 Synapse (credit: Curtis Neveu/Wikimedia Commons) New UCLA research indicates that lost memories can be restored, offering hope for patients in the early stages of Alzheimer’s disease. For decades, most neuroscientists have believed that memories are stored at the synapses — the connections between brain cells, or neurons — which are destroyed by Alzheimer’s disease. The new study provides evidence contradicting the idea that long-term memory is stored at synapses. “Long-... mais »

Color-coding brain cellsDecember 23, 2014 *[+]* Multicolor tracing of newborn neurons. (credit: University of Southampton) University of Southampton neuroscientists have developed a method called “multicolor RGB tracking” to improve our understanding of how the brain works by color-marking individual brain cells in mice allows them to be tracked over space and time.*/.../

Molecular structures in proteins

Hidden molecular structures in proteins revealed Improved X-ray diffraction software uses statistical methods December 23, 2014 A membrane protein called cysZ, imaged in three dimensions with Phenix software, using data that could not previously be analyzed (credit: Los Alamos National Laboratory) Los Alamos National Lab scientists have developed statistical methods that allow for creating three-dimensional pictures of previously hidden molecular structures in proteins. To view the proteins, researchers produce billions of copies, dissolve them in water, and grow crystals of the protei... mais »

Quantum "uncertainty principle"

Aloyzio AchuttiemAMICOR - Há um dia
Quantum physics just got less complicated Is "wave-particle duality" simply the quantum "uncertainty principle" in disguise? December 23, 2014 *[+]* Quantum physics says that particles can behave like waves, and vice versa. Researchers have now shown that this “wave-particle duality” is simply the quantum uncertainty principle in disguise (credit: Timothy Yeo/CQT, National University of Singapore) An international team of researchers has proved that two peculiar features of the quantum world previously considered distinct are different manifestations of the same thing. They found that... mais »

Existing drug riluzole may prevent foggy ‘old age’ brain December 24, 2014 [image: When researchers looked at certain neurons (similar to the one shown on top) in rats treated with riluzole, they found an important change in one brain region, the hippocampus: more clusters of so-called spines, receiving connections that extend from the branches of a neuron (bottom). (Credit: Dr. John H. Morrison's lab, The Icahn School of Medicine at Mount Sinai)] New experiments suggest that riluzole, a drug already on the market as a treatment for ALS (Lou Gehrig’s disease), may help prevent the fad... mais »

Optogenetics captures synaptic transmission in live mammalian brain for the first time Could significantly expand our knowledge of connectivity between various types of neurons as a more realistic alternative to in vitro studies December 26, 2014 A reconstruction of a pair of synaptically connected neurons (credit: Aurélie Pala/EPFL) EPFL scientists Aurélie Pala and Carl Petersen have observed and measured synaptic transmission in a live animal for the first time, using optogenetics* to stimulate single neurons in the mouse barrel cortex (which processes sensory information from the m... mais »

Uma foto histórica - autor: Bortolo Achutti

José Antonio BrenneremBrenner de Santa Maria - Há 6 dias
Em 30 de junho de 1985, o Centro de Tecnologia da UFSM completou 25 anos de fundação. Organizei, na época, uma exposição comemorativa, no saguão de Centro de Tecnologia, com fotos, documentos e instrumentos. A coleta de documentos e, principalmente, de fotografias exigiu uma laboriosa busca em vários setores da Universidade. Uma das fotos expostas tem grande valor histórico para o Centro de Tecnologia e para a UFSM. Não sei em que dia foi tomada, mas eu a denominei *O “Dia do sim”* No ano de 1958, o Prof. José Mariano da Rocha Filho, então presidente da ASPES-Associação Santa-Mariens... mais »
