Targeting Brain's Drainage Pathways Rejuvenates Memory (neurosciencenews.com)
Now, researchers at Washington University School of Medicine in St. Louis report they have found a way around that problem by targeting the network of vessels that drain waste from the brain. Rejuvenating those vessels, they have shown, improves memory in old mice.

For Many of America's Aging Workers, 'Retirement Is a Distant Dream' (time.com)
Walter Carpenter walks across the ski resort’s dining room on a knee that needs to be replaced and a hip that’s going bad. Lumbering into the kitchen, he deposits a brown bin of dirty dishes on a counter before heading back out to collect more bowls of half-eaten tomato soup and plates littered with sandwich crusts. “One foot in front of the other,” he jokes to kitchen prep worker Kim Hopper, 72, as they pass each other.

Body wasn't built to last: a lesson from human mortality rates (2009) (wordpress.com)
What do you think are the odds that you will die during the next year? Try to put a number to it — 1 in 100? 1 in 10,000? Whatever it is, it will be twice as large 8 years from now.

Changes in brain's 'sugar shield' could be key to understanding effects of aging (news.stanford.edu)
What if a critical piece of the puzzle of brain aging has been hiding in plain sight? While neuroscience has long focused on proteins and DNA, a team of Stanford researchers dared to shift their gaze to sugars – specifically the complex sugar chains that cover all our cells like chain mail.

Facing the Music or Burying Our Heads in the Sand? (nlm.nih.gov)
Defenses that keep threatening information out of awareness are posited to reduce anxiety at the cost of longer-term dysfunction. By contrast, socioemotional selectivity theory suggests that preference for positively-valenced information is a late-life manifestation of adaptive emotion regulation.
