‘The genome was subjected to some durable deletion mechanisms.’ Plant exclusive among close relatives There is likely a solid evolutionary benefit to removing redundant DNA, the researchers speculated. ‘If you have the type of rampant DNA deletion that we discover in the bladderwort, genes that are less important or redundant are easily lost,’ says Albert. ‘The genes that remain – and their features – will be the types that were in a position to withstand this deletion pressure, therefore the selective advantage of having these genes must be pretty high.’ Certainly, the researchers discovered that the bladderwort was particularly more likely to delete genes that didn’t directly relate to survival, also to retain those linked to traits such as wearing down food or maintaining solid cell walls.The Kaiser Daily Health Policy Report is published for Kaisernetwork.org, a free of charge services of The Henry J.

Artificial pancreas breakthrough presents solution for health ramifications of eating artificial food It’s downright amazing: A biomedical engineer at Boston University has developed a so-called artificial pancreas that helps diabetics maintain well balanced blood sugar levels by monitoring the bloodstream and releasing either insulin or glucagon as required. Now all those people who eat artificial food advertised through artificial worlds on television can truly add an artificial pancreas to their artificial health care plan.
