Finding Meaning in a Crazy World

Aloyzio AchuttiemAMICOR - Há 6 minutos
** Anne Lamott on How We Endure and Find Meaning in a Crazy World We live in a culture of dividedness and fragmentation of the self. When we contemplate what it takes to live a full life, we extol mindfulness and wholeheartedness. But being wholehearted is only sufficient if your heart is your whole self; being mindful is only sufficient if your mind is all you are. We are, of course, so much more expansive than our hearts and our minds and our perfect abs, or whatever fragment we choose to fixate o... mais »

Longer life?

Aloyzio AchuttiemAMICOR - Há 10 horas
*Selecionado pela AMICOR Maria Inês Reinert Azambuja* *AGING The downside of living a longer life * SCIENCE 30 JANUARY 2015 • VOL 347 ISSUE 6221 517 Over the years, scientists have identified many factors that increase longevity in animal models. But do these interventions also let animals stay healthy longer, giving them an extended “healthspan”? To find out, Bansal et al. measured a range of physiological parameters over the lifetime of worms with mutations that extended their lifespans. The effect of these mutations on healthspan was variable. In fact, control worms ... mais »

Brain-to-brain communication

[image: TED] TALK OF THE WEEK Miguel Nicolelis: Brain-to-brain communication has arrived. How we did it 18:57 minutes · Filmed Oct 2014 · Posted Jan 2015 · TEDGlobal 2014 You may remember neuroscientist Miguel Nicolelis — he built the brain-controlled exoskeleton that allowed a paralyzed man to kick the first ball of the 2014 World Cup. What’s he working on now? Building ways for two minds (rats and monkeys, for now) to send messages brain to brain. Watch to the end for an experiment that, as he says, will go to "the limit of your imagination." Watch now »

Looser Hypertension Guidelines Could Still Save Lives, $$ Even the less aggressive 2014 targets would be better than the status quo, study shows. If new and controversial treatment recommendations for adults with hypertension were fully implemented, there would be 13,000 fewer deaths annually than if the status quo was continued, claims a new study that simulated costs over 10 years.

Genome-wide search reveals >750 worm genes involved in long-term memoryJanuary 25, 2015 Whole-genome expression data reveals new genes involved in long-term memory formation in worms (credit: Murphy lab) A new Princeton University study has identified more than 750 genes involved in long-term memory in the worm — part of research aimed at finding ways to retain cognitive abilities during aging, including compounds. The study takes a different approach than the recentENIGMA study, which identified genetic mutations in humans related to brain aging. The new study, published in the jour... mais »

Higher dementia risk linked to more use of common drugsJanuary 27, 2015 (Credit: iStock) A large study links a significantly increased risk for developing dementia, including Alzheimer’s disease, to taking commonly used medications with anticholinergiceffects at higher doses or for a longer time. Many older people take these medications, which include nonprescription diphenhydramine (Benadryl) and related drugs. *JAMA Internal Medicine *published the report, called “Cumulative Use of Strong Anticholinergic Medications and Incident Dementia.” It’s been known for some time that memory or ... mais »

The cell nucleus is stained blue. (Credit: Franklin F. Duan et al./Diabetes) Imagine a pill that helps people control diabetes with the body’s own insulin to lower blood glucose levels. Cornell researchers have achieved this feat in rats by engineering human lactobacilli, a common gut bacteria, to secrete a protein that modifies inte... mais »

Were Cellular Powerhouses Once Parasites?*Thomas Fuchs* Mitochondria may have started out stealing energy rather than producing it Jan 20, 2015 |By Annie Sneed Mitochondria, the organelles known to every junior high school student as “the powerhouses of the cell,” go back some two billion years. Although these energy producers were identified in the 1800s, how they became fixtures in cells is still under debate. Mitochondria's ancestor was a free-living bacterium that another single-celled organism ingested. Most biologists think that the bacterium benefited the host: in one hypothe... mais »

Nossa turma de estudantes da Faculdade de Arquitetura da UFRGS, quando cursava o 4º ano, fez uma viagem de estudos a Rio Pardo, em 1957, possivelmente em setembro ou outubro. A viagem foi promovida pelo Prof. João Baptista Pianca, da disciplina de Arquitetura no Brasil, para conhecer o patrimônio edificado, notadamente a Matriz N. S.ra do Rosário e a Capela de São Francisco, além da estatuaria sacra. Matriz N. Senhora do Rosário Rio Pardo é um dos mais antigos e importantes municípios da história rio-grandense, que tem suas raízes no forte Jesus, Maria e José, construído em 175... mais »
