How worms survive desiccation
While life requires water, many organisms, known as anhydrobiotes, can survive in the absence of water for extended periods of time. Although discovered 300 years ago, we know very little about the fascinating phenomenon of anhydrobiosis. In this paper, we summarize our previous findings on the desiccation tolerance of the Caenorhabditis elegans dauer larva. A special emphasis is given to the r...
متن کاملHow robins find worms
An understanding of diet selection in animals requires knowledge of not only what animals eat in relation to what is available, but also how they perceive the foods available to them. Birds use auditory, visual, olfactory and possibly vibrotactile cues to find prey, but vision is the predominant mode of prey detection. In a series of controlled experiments in an aviary, four American robins, Tu...
متن کاملSex Determination: How Worms Count to Two
A century ago, Bridges proposed that male genes on the autosomes and female genes on the X chromosome compete to determine sexual identity. New genetic and molecular studies establish Caenorhabditis elegans as the first animal known to use this mechanism.
متن کاملSeparating cause from effect: how does insulin/IGF signalling control lifespan in worms, flies and mice?
Ageing research has been revolutionized by the use of model organisms to discover genetic alterations that can extend lifespan. In the last 5 years alone, it has become apparent that single gene mutations in the insulin and insulin-like growth-factor signalling pathways can lengthen lifespan in worms, flies and mice, implying evolutionary conservation of mechanisms. Importantly, this research h...
متن کاملHow many guests, what sort of hosts?
To the Editor: Lansing et al. (1) offer an intriguing approach to the prehistory of the island of Sumba. There is at least one critical f law in the reasoning used, the assumption that the languages of Sumba form a subgroup, being all derived from a single ancestral language, Proto-Sumba. The comparative method used by the authors allows us to subgroup languages together if two criteria are met...
