The presence of male roundworms may shorten females' lifespan
Researchers at the Stanford University School of Medicine have discovered that males of the laboratory roundworm secrete signaling molecules that significantly shorten the lifespan of the opposite sex.The scientists speculate that, if carried out after reproduction, this "male-induced demise" could serve to conserve precious resources for a male's offspring or to decrease the supply of mates for other males.For several years, it's been known that the presence of some male worms and flies can shorten the lifespan of their female or hermaphroditic counterparts.

Worm study provides clues to better fat-loss therapies for humans
Scientists at The Scripps Research Institute (TSRI) have discovered key details of a brain-to-body signaling circuit that enables roundworms to lose weight independently of food intake. The weight-loss circuit is activated by combined signals from the worm versions of the neurotransmitters serotonin and adrenaline, and there are reasons to suspect that it exists in a similar form in humans and other mammals...

Could niacin be the fountain of youth?
The vitamin niacin has a life-prolonging effect, as Michael Ristow has demonstrated in roundworms. From his study, the ETH-Zurich professor also concludes that so-called reactive oxygen species are healthy, not only disagreeing with the general consensus, but also many of his peers. Who would not want to live a long and healthy life? A freely available food supplement could help in this respect, scientists from ETH Zurich have demonstrated in roundworms...

Right combination of sugars regulates brain development, from worm to man
If the development of our nervous system is disturbed, we risk developing serious neurological diseases, impairing our sensory systems, movement control or cognitive functions. This is true for all organisms with a well-developed nervous system, from man to worm. New research from BRIC, University of Copenhagen reveals how a tiny molecule called mir-79 regulates neural development in roundworms. The molecule is required for correct migration of specific nerve cells during development and malfunction causes defects in the nervous system of the worm...

Biologists uncover details of how we squelch defective neurons
Biologists at the University of California, San Diego have identified a new component of the cellular mechanism by which humans and animals automatically check the quality of their nerve cells to assure they're working properly during development. In a paper published in this week's issue of the journal Neuron, the scientists report the discovery in the laboratory roundworm C. elegans of a "quality check" system for neurons that uses two proteins to squelch the signals from defective neurons and marks them for either repair or destruction...

Five diseases that are, thankfully, consigned to the past | Richard Sugg
Richard III's roundworm was just one of the gruesome diseases that killed and maimed the British population through the agesThe news that Richard III suffered from roundworm reminds us how grateful we should be for the advances of modern sanitation and medicine. In both Richard's era and long after, rich and poor were horribly vulnerable to diseases that either killed you efficiently or made you wish you were dead.1. Sweating sicknessIf Richard had not died at Bosworth field in 1485, he might well have been struck down by this malady. First recorded in Shrewsbury in mid-April 1485, this terrifying new disease had reached L...
