Rebooting immune cells’ metabolism shields the aging brain in mice – NIA

Scientists recently discovered a process by which immune cells can drive aging in the brain, and how to block this pathway to improve memory and maze navigation in older mice. The findings suggest a potential avenue to develop new treatments for cognitive conditions like Alzheimer’s disease. The study, led by researchers from Stanford University, was published in Nature on Jan. 20.

Inflammation is part of the immune system response to infection or injury. But as people age, they may have chronic low-level inflammation, which is linked to age-related diseases and cognitive decline.

Normally, immune cells — including a group of cells called macrophages — create immune responses that protect the brain, such as disposing of abnormal forms of proteins that are tied to neurodegeneration. But as people — and mice — age, immune cells can start encouraging inflammation rather than protecting against it.

Musicians have faster reflexes – Study

I always loved that famous William Congreve quote – ” Music has charms that soothe the savage breast.” It’s often misquoted as the savage breast. I confess, I am a music lover. Sadly, the only instrument I play is my stereo. I never got around to actually learning how to play an actual instrument. More’s the pity.


Researchers at University of Montreal’s audiology school find that musicians have faster reaction times than non-musicians – and that could have implications for the elderly.

Could learning to play a musical instrument help the elderly react faster and stay alert?

Quite likely, according to a new study by Université de Montréal’s School of Speech Language Pathology and Audiology, part of UdeM’s medical faculty.

Published in the U.S. journal Brain and Cognition, the study shows that musicians have faster reaction times to sensory stimuli than non-musicians have.

And that has implications for preventing some effects of aging, said lead researcher Simon Landry, whose study is part of his doctoral thesis in biomedical science.

“The more we know about the impact of music on really basic sensory processes, the more we can apply musical training to individuals who might have slower reaction times,” Landry said.

“As people get older, for example, we know their reaction times get slower. So if we know that playing a musical instrument increases reaction times, then maybe playing an instrument will be helpful for them.”
