Stem cells, ageing and the quest for immortality

Adult stem cells reside in most mammalian tissues, but the extent to which they contribute to normal homeostasis and repair varies widely. There is an overall decline in tissue regenerative potential with age, and the question arises as to whether this is due to the intrinsic ageing of stem cells or, rather, to the impairment of stem-cell function in the aged tissue environment. Unravelling these distinct contributions to the aged phenotype will be critical to the success of any therapeutic application of stem cells in the emerging field of regenerative medicine with respect to tissue injury, degenerative diseases or normal functional declines that accompany ageing.

黑洞研究中的重要疑难及可能的解答

介绍了黑洞理论和广义相对论中的几个重要疑难,涉及霍金辐射、信息佯谬、奇性定理和钟速同步,并给出了可能的解答。介绍了计算动态黑洞温度的方法,给出了由于不可逆性而导致霍金辐射过程中信息丢失的论证,还给出了类光测地线固有加速度发散的论证。指出了钟速同步与热力学第零定律的关系,以及奇性定理与热力学第三定律的关系。     

Oxidants, oxidative stress and the biology of ageing

Living in an oxygenated environment has required the evolution of effective cellular strategies to detect and detoxify metabolites of molecular oxygen known as reactive oxygen species. Here we review evidence that the appropriate and inappropriate production of oxidants, together with the ability of organisms to respond to oxidative stress, is intricately connected to ageing and life span.
