Marcus Aurelius on Mortality
Marcus Aurelius on Mortality and the Key to Living Fully“The only thing that isn’t worthless: to live this life out truthfully and rightly. And be patient with those who don’t.”BY MARIA POPOVA *“Death is our friend,”* Rilke wrote in an exquisite 1923 letter, *“precisely because it brings us into absolute and passionate presence with all that is here, that is natural, that is love.”* And yet one of the defining features of the human condition is that we long for immortality despite inhabiting a universe governed by impermanence. Eighteen centuries before Rilke, the great Roman emperor ... mais »

AD and Corticotropin
Modulating brain’s stress circuity might prevent Alzheimer’s disease November 17, 2015 [image: AD drug treatment ft] Drug significantly prevented onset of cognitive and cellular effects in mice In a novel animal study design that mimicked human clinical trials, researchers at University of California, San Diego School of Medicine report that long-term treatment using a small-molecule drug that reduces activity of the brain’s stress circuitry significantly reduces Alzheimer’s disease (AD) neuropathology and prevents onset of cognitive impairment in a mouse model of the … more…
Exercise and neurodegenerative diseases
Exercise may protect against neurodegenerative diseases November 19, 2015 [image: (credit: iStock)] Exercise may protect aging brains against the neurodegenerative diseases resulting from energy-depleting stress caused by neurotoxins and other factors, according to researchers at the National Institute on Aging Intramural Research Program and Johns Hopkins University School of Medicine. They found that running-wheel exercise increased the amount of SIRT3 in neurons of normal mice and protected … more…

brain’s genetic patterns
Allen Institute scientists identify human brain’s most common genetic patterns BY ALAN BOYLE on November 16, 2015 at 8:00 am [image: Gene expression in human brain]An image from the Allen Brain Explorer shows gene expression across the human brain. (Credit: Allen Institute for Brain Science) Researchers say they’ve traced 32 of the most common genetic patterns at work in the human brain, as part of a mapping project that could lead to new insights about Alzheimer’s and other diseases. “We’re really trying to understand the genetic basis for the architecture of the human brain,” said ... mais »
AD drug harms
Alzheimer’s drug found to cause harm to mouse brain cells [image: Alzheimer's drug found to cause harm to mouse brain cells] Could it make Alzheimer’s worse? Animal studies suggest that an antibody similar to one being trialled in people for the treatment of Alzheimer’s might actually be harmful. Antibodies are currently undergoing trials in humans, as they have been found to break down the sticky plaques that build up in the brain. But in mice with a version of Alzheimer’s, antibodies that work the same way seem to make brain cells hyperactive and then eventually stop functioning. “We... mais »

Urban Food Foraging
Urban Food Foraging Looks Fruitful Fruits growing wild in urban areas were found to be healthful and to contain lower levels of lead than what's considered safe in drinking water By Cynthia Graber | November 18, 2015 00:00 01:45 Download MP3 Foraging for food in urban areas is on the rise. Not dumpster diving. Collecting fruits and herbs. Throughout cities, forgotten fruit trees still produce, well, produce. For example, there was a peach tree in my former backyard in Somerville, near Boston. And today there are even maps to some of those trees so foragers can take advantage of free ... mais »

Exploring Our Bacterial Ecosystem By Katherine S. Pollard, PhD / Gladstone News / November 17, 2015 [image: Dr. Katie Pollard] The human microbiome plays a role in processes as diverse as body composition, immune function, and mental health. Katherine Pollard studies these microbes to learn how they influence health and disease. [Photo: Chris Goodfellow] Cellularly and genetically, we are more “other” than human. The human microbiome—the diverse array of bacteria, yeast, parasites, and other single-celled organisms that live in and on our bodies—is comprised of more microbes than the... mais »

Prostate Cancer Screening
Early Prostate Cancer Cases Fall Along With Screening By DENISE GRADYNOV. 17, 2015 Fewer men are being screened for prostate cancer, and fewer early-stage cases are being detected, according to two studies published Tuesday in The Journal of the American Medical Association. - - The number of cases has dropped not because the disease is becoming less common but because there is less effort to find it, the researchers said. The declines in both screening and incidence “could have significant public health implications,” the authors of one of the studies wrote, but they a... mais »
