Using Nematode worms
, scientists found even those given enhanced antioxidant powers to deal with tissue damaging "free radicals" did not live longer.

By studying the process of symmetry breaking in zygotes from the nematode worm
Caenorhabditis elegans, his team previously revealed how forces generated on the cortex by the contractions of the actin cytoskeleton (a filamentous framework made of actin and myosin proteins) could direct the movement of polarity regulators to their destined locations.
HGT is thought to play an important role in the evolution of some animals, including nematode worms
which have acquired genes from microorganisms and plants, and some beetles that gained bacterial genes to produce enzymes for digesting coffee berries.
The disease is caused by the nematode worm
Their work, which hinged around studies of a tiny nematode worm
, identified key genes regulating organ development and the programmed death of cells.
The work on the nematode worm
is described as a breakthrough on a par with the cloning of Dolly the sheep.
The nematode worm
Anisakis simplex can cause serious health problems, especially in pregnant women and elderly people.
We also share many genes with more humble organisms - about half with the fruitfly and the nematode worm
, and about a fifth with yeast.
The creature is a soil-dwelling nematode worm
, less than one millimetre long.
There is even the little-known nematode worm
which invades humans, animals, soil and plants.
Sirtuins had previously been linked to ageing and longevity in yeast, the nematode worm
and the fruit fly, organisms commonly used as models for the biology of human ageing.
