 Adult Physical Activity Keeps Immune System Young

It is widely accepted that aging is accompanied by remodelling of the immune system including thymic atrophy and increased frequency of senescent T cells, leading to immune compromise. However, physical activity, which influences immunity but declines dramatically with age, is not considered in this literature. We assessed immune profiles in 125 adults (55–79 years) who had maintained a high level of physical activity (cycling) for much of their adult lives, 75 age-matched older adults and ...

As we store more of our memories externally and create avatars, it is also becoming increasingly apparent that the bounda...

 Watson's Afterward Concerning Rosalind Franklin

All of these people, should they desire, can indicate events and details they remember differently. But there is one unfortunate exception. In 1958, Rosalind Franklin died at the early age of thirty-seven. Since my initial impressions of her, both scientific and personal (as recorded in the early pages of this book), were often wrong, I want to say something here about her achievements. The X-ray work she did at King's is increasingly regarded as superb. The sorting out of the A and B forms, ...

 Animal Instinct and Child Birth

What, then, is the difference between human and other animals? Are their bodies made differently? As a matter of fact they are remarkably similar. Cat and dog bodies are used in premedical anatomy studies due to the similarity of structures with identical name and function. Is it that they just can't experience pain? Following a natural-childbirth newspaper article, an indignant letter to the editor asserted cats can have kittens without pain because they cannot feel pain as human beings do...
