Stowers team develops novel assay to identify genes controlling pharynx regeneration in flatworms As multicellular creatures go, planaria worms are hardly glamorous. To say they appear rudimentary is more like it. These tiny aquatic flatworms that troll ponds and standing water resemble brown tubes equipped with just the basics: a pair of beady light-sensing "eyespots" on their head and a feeding tube called the pharynx (which doubles as the excretory tract) that protrudes from a belly sac...

One Of The 100 Worst Invasive Alien Species In The World Now Found In Europe
2014-03-04 10:34:12

PeerJ One of the consequences of globalization and increased worldwide freight trade is the introduction of invasive alien species. In the list of the 100 worst invasive alien species in the world , there is only one terrestrial flatworm: Platydemus manokwari, also called New Guinea flatworm. This species has now been found in France, Caen, and was identified by an international team led by Jean-Lou Justine of Institute of Systematics, Evolution, Biodiversity, Paris, France (Muséum...

Mahal

April Flowers for redOrbit.com - Your Universe Online A famous orangutan that lived an extraordinary life, died in a rather extraordinary way as well. Mahal, one of the stars of the Milwaukee County Zoo, was an emblem of survival for a dwindling species. Mahal was born in the Cheyenne Mountain Zoo in Colorado Springs, Colorado, five years ago. He was rejected by his birth mother, which is how he ended up in Milwaukee. The young primate was flown aboard a private jet to a surrogate...

Planarian flatworms have come under intense study for their renowned ability to regenerate any missing body part, even as adults. But now they may take on a starring role as a model system for studying eye development and eye diseases in vertebrates, including humans. This expansion of the planarian job description comes courtesy of Whitehead Institute researchers, who this week are publishing in Cell Reports an exhaustive catalog of genes active in the planarian eye. "It's exciting to...

Researchers at the University of California, San Francisco and the Stowers Institute for Medical Research have discovered that planarians, tiny flatworms fabled for their regenerative powers, completely lack centrosomes, cellular structures that organize the network of microtubules that pulls chromosomes apart during cell division. The flatworms' unique and unexpected characteristic, detailed in the Jan. 5, 2012 issue of Science Express, not only allowed lead author Juliette Azimzadeh,...

Flatworms provide new insight into organ regeneration and the evolution of mammalian kidneys Our bodies are perfectly capable of renewing billions of cells every day but fail miserably when it comes to replacing damaged organs such as kidneys. Using the flatworm Schmidtea mediterranea"”famous for its capacity to regrow complete animals from minuscule flecks of tissue"”as an eloquent example, researchers at the Stowers Institute for Medical Research demonstrated how our distant...

Researchers of the Berlin Institute for Medical Systems Biology (BIMSB) at the Max Delbrck Center for Molecular Medicine (MDC) Berlin-Buch have gained new insights into planarian flatworms, which are an attractive model for stem cell biology and regeneration. Close collaboration between four laboratories at the BIMSB led by Stefan Kempa, Christoph Dieterich, Nikolaus Rajewsky and Wei Chen has led to the identification of thousands of gene products, many of which are expressed and are...

Worm with abundant ability to regenerate relies on ancient gene to make decisions Most people don't think worms are cool. But the tiny flatworm that Northwestern University scientist Christian Petersen studies can do something very cool indeed: it can regenerate itself from nearly every imaginable injury, including decapitation. When cut in half, it becomes two worms. This amazing ability of the planarian flatworm to regenerate its entire body from a small wedge of tissue has fascinated...

Scientists reorganise the animal phylogenetic tree An international team of scientists including Albert Poustka from the Max Planck Institute for Molecular Genetics in Berlin has discovered that Xenoturbellida and the acoelomorph worms, both simple marine worms, are more closely related to complex organisms like humans and sea urchins than was previously assumed. As a result they have made a major revision to the phylogenetic history of animals. Up to now, the acoelomate worms were viewed as...

"Man is but a worm" was the title of a famous caricature of Darwin's ideas in Victorian England. Now, 120 years later, a molecular analysis of mysterious marine creatures unexpectedly reveals our cousins as worms, indeed. An international team of researchers, including a neuroscientist from the University of Florida, has produced more evidence that people have a close evolutionary connection with tiny, flatworm-like organisms scientifically known as "Acoelomorphs." The research in the...

Nightcrawler, Lumbricus terrestris
2014-01-12 00:00:00

The nightcrawler (Lumbricus terrestris), also known as the lob worm or the common earthworm in Britain and the dew worm in Canada, is a species of earthworm that is classified within the Annelida phylum. It is native to Europe, but has been introduced into other areas around the world. Although the species is not as abundant as other worms in its range, it is a widely known species in gardens of temperate habitats, where it moves about on the surface of the soil. The nightcrawler can reach...

Rodent Tapeworm. Hymenolepis microstoma
2014-01-12 00:00:00

The rodent tapeworm (Hymenolepis microstoma) is a parasitic worm that is classified within the Platyhelminthes phylum. This species affects rodents across the world, causing hymenolepiasis, but it does not often affect humans. Most of the available information regarding tapeworms is derived from the studies conducted on this worm and the other members of its genus, Hymenolepis. These worms have been present in laboratories since the 1950's and can either be raised and kept in a culture or be...

Dwarf Tapeworm, Hymenolepis nana
2014-01-12 00:00:00

The dwarf tapeworm (Hymenolepis nana) is a species of tapeworm that is classified in the Platyhelminthes phylum. It once held three other scientific names including Vampirolepis nana and Taenia nana. It is found throughout the world but occurs most often in temperate regions. As its common name implies, the dwarf tapeworm is small, reaching an average body length of 1.5 inches. The head, or scolex, holds a retractable beak like organ that has twenty to thirty hooks and four string suckers,...

Beef Tapeworm

The beef tapeworm (Taenia saginata or Taeniarhynchus saginata) is a species of tapeworm that is classified within the Platyhelminthes phylum. It can affect both cattle and humans, and causes the disease taeniasis in humans. It can be found in many areas that have a beef market including Africa, the Philippines, Latin America, and Eastern Europe, although it is not abundant in this area. It does occur in the United States, but it is not common due to high sanitation standards. The beef...
