Stem Cells In A Human Parasite Revealed Through Study
2013-02-26 09:31:26

University of Illinois From the point of view of its ultimate (human) host, the parasitic flatworm Schistosoma mansoni has a gruesome way of life. It hatches in feces-tainted water, grows into a larva in the body of a snail and then burrows through human skin to take up residence in the veins. Once there, it grows into an adult, mates and, if it´s female, starts laying eggs. It can remain in the body for decades. A new study offers insight into the cellular operations that give...

Understanding Organ Regeneration Using Planarian Flatworms
2012-10-25 12:26:38

In a new study published in the October 16 issue of Developmental Cell, corresponding author Professor of Cell and Developmental Biology and Howard Hughes Medical Institute Investigator Phillip Newmark and colleagues report the identification of genes that control growth and regeneration of the intestine in the freshwater planarian Schmidtea mediterranea. How animals repair their internal organs after injury is not well understood. Planarian flatworms are useful models for studying this...

A study of peptide hormones in the brain of a seemingly primitive flatworm reveals the surprising complexity of its nervous system and opens up a new approach for combating a major parasitic disease, researchers report. The study appears in the open-access journal PLoS Biology. The planarian flatworm, Schmidtea mediterranea, is perhaps best known for its prodigious powers of regeneration. Cut it in half (lengthwise or crosswise) and each fragment will regrow its missing parts, including its...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
