Striking accumulation of PUFA in aged cells

Peat has written many times about the changes that occur in “aged” cells. Those changes are virtually indistinguishable from the ones that occur in “sick” cells and are characterized by reduced mitochondrial number/size and a shift in lipid composition away from saturated and towards unsaturated fats. The crucial mitochondrial lipid enzyme cardiolipin (CL) comprises at … Read more Striking accumulation of PUFA in aged cells

Millennials will likely die earlier than Gen X due to poor(er) health

This study is perhaps the pearl in the crown of at least 20 studies that have come out over the 2-3 years. It finally states what has been abundantly clear from those prior studies in individual diseases. Namely, there are no young / healthy people any more. Both the Generation X (Gen X) and Millennials … Read more Millennials will likely die earlier than Gen X due to poor(er) health

Poverty makes people dumb and prematurely old

A common debate in public policy is whether people slide into poverty because they are stupid or being poor makes people stupid and unable to cope with life. The study below adds some evidence to the latter claim and found that extended poverty (20 years or longer) exposure also causes premature aging. Perhaps one of … Read more Poverty makes people dumb and prematurely old

New science blooms after “stars” die

As the article aptly quotes Max Planck, the running joke in physics for the last 100+ years has always been that science advances “one funeral at a time”. However, up until the study below came out this informal statement/knowledge was viewed as little more than the gripe of cynical, disillusioned, overworked post-docs. Shockingly, it appears … Read more New science blooms after “stars” die

If current trends hold, within a decade the entire population may become autistic

Peat published a newsletter not long ago in which he presented evidence that not only are autism rates rising but the general population is starting to exhibit some signs/symptoms of the condition. I think he called the phenomenon a “generation-wide autism”. The study below alarmingly predicts that if current trends hold within the next decade … Read more If current trends hold, within a decade the entire population may become autistic

Deficiency of vitamin K involved in age-related disability / frailty

A nice study illustrating that vitamin K deficiency may be one of the reasons people become frail with age. Age-relate disability/frailty is one the leading causes of death in the elderly, behind infections and iatrogenic causes. Given the role of vitamin K in the synthesis of osteocalcin and consequently insulin and steroids, the findings of … Read more Deficiency of vitamin K involved in age-related disability / frailty
