Similarities and Differences between Induced Organ Regeneration in Adults and Early Fetal Regeneration by Professor IV Yannas

The interest of this article to the public centres on the discovery that non-functioning organs can be regenerated in adults by use of scaffolds alone (or scaffolds seeded with the subject's own epithelial cells). This development may obviate the use of organ transplants in the future. Also note that, in this treatment, stem cells are not required to be used by the investigator. It has been widely thought previously that only the early mammalian foetus can regenerate an organ spontaneously following severe injury to that organ. It is now clear that the adult is capable of a regenerative potential that was previously considered to have become lost just before birth. This discovery suggests the possibility that adults (you and I) have managed to retain their early foetal potential to regenerate organs; and that this dormant potential can be reactivated provided that medical researchers can identify the appropriate agents (scaffolds, small molecules, etc.) that awaken the early foetal response to injury. The emerging field of Regenerative Medicine is based on this new treatment that leads to organ regeneration and provides an outlook toward increased longevity.

Diving behaviour of whale sharks in relation to a predictable food pulse by Dr RT Graham, Professor CM Roberts and Dr JCR Smart

We present diving data for four whale sharks in relation to a predictable food pulse (reef fish spawn) and an analysis of the longest continuous fine-resolution diving record for a planktivorous shark. Fine-resolution pressure data from a recovered pop-up archival satellite tag deployed for 206 days on a whale shark were analysed using the fast Fourier Transform method for frequency d
