Decreasing the intake of calories and tweaking the activity of the hormone insulin are two methods long known to increase lifespan in a wide range of organisms. In particular, studies have shown that longevity can be extended by reducing activity in the insulin-signaling pathway -- a chain of events through which insulin influences numerous biological processes, including metabolism, stress response and development. Now, a team of Princeton biologists has found the first evidence that these...

Scientists at The University of Nottingham have discovered the gene that enables an extraordinary worm to regenerate its own body parts after amputation "” including a whole head and brain. Their research into the Planarian worm is another piece in the scientific jigsaw that could one day make the regeneration of old or damaged human organs and tissues a real possibility. The research led by Dr Aziz Aboobaker, a Research Councils UK Fellow in the School of Biology shows for the first...

A new combination drug treatment for parasitic intestinal roundworms shows promise in a test on a common laboratory species. Several drugs currently in use or in development control parasitic worms in the same way. That concerns health workers In developing countries where reinfestations often require repeated treatments. If worms develop resistance to one drug, the other treatments would likely fail as well. Raffi Aroian's research group at the University of California, San Diego recently...

Biologists at UC San Diego have discovered that a protein from a soil bacterium used to kill insects naturally on organic crops is a highly effective treatment for intestinal parasitic roundworms. These parasites, which include hookworms and whipworms, infect about two billion people in underdeveloped tropical regions and are cumulatively one of the leading causes of debilitation worldwide. The scientists report in the March 2 issue of the open-access journal PLoS Neglected Tropical Diseases,...

In an advance with overtones of Star Trek phasers and other sci-fi ray guns, scientists in Canada are reporting development of an internal on-off "switch" that paralyzes animals when exposed to a beam of ultraviolet light. The animals stay paralyzed even when the light is turned off. When exposed to ordinary light, the animals become unparalyzed and wake up. Their study appears in the Journal of the American Chemical Society (JACS). It reports the first demonstration of such a light-activated...

Microscopic nematode worms can be a potent organic insecticide, killing crop-raiding bugs without harming plants or beneficial insects and without the environmental side effects of chemicals. But when the worms are mass-bred for agricultural purposes, they tend to, as Byron Adams says, "wimp out," and are not as deadly as their cousins that grow in the wild. The Brigham Young University biology professor and his students analyzed the genetic changes in lab-raised worms that make them less...

A Nobel-winning process for testing new drugs to treat diseases such as Huntington's, Parkinson's, and muscular dystrophy is getting an electrical charge. Researchers at McMaster University have developed a way to propel and direct microscopic-sized worms (C. elegans nematodes) along a narrow channel using a mild electric field. The discovery opens up significant possibilities for developing high-throughput micro-screening devices for drug discovery and other applications. "This is the first...

It sounds like a classic horror story"”eyeless, mouthless worms lurk in the dark, settling onto dead animals and sending out green "roots" to devour their bones. In fact, such worms do exist in the deep sea. They were first discovered in 2002 by researchers at the Monterey Bay Aquarium Research Institute (MBARI), who were using a robot submarine to explore Monterey Canyon. But that wasn't the end of the story. After "planting" several dead whales on the seafloor, a team of biologists...

The females of the recently discovered Osedax marine worms feast on submerged bones via a complex relationship with symbiotic bacteria, and they are turning out to be far more diverse and widespread than scientists expected. Californian researchers investigating the genetic history of Osedax worms have found that up to twelve further distinct evolutionary lineages exist beyond the five species already described. The new findings about these beautiful sea creatures with unusual sexual and...

Caecilian
2014-01-28 12:32:06

The Sagalla caecilian (Boulengerula niedini) is a long, earthworm-like amphibian from the family Caeciliidae. The species is native to the tiny area of south-eastern Kenya called Sagalla Hill. The Sagalla caecilian has a slender body, perfect for burrowing. Its skin is extremely pigmented, lending it a brownish color with a pinkish-red hint, and white cross segments that give the appearance of grooves. They can grow up to 12 inches in length. Along with tough skin and a bony head, the...

Trumpet Worm, Lagis koreni

The trumpet worm (Lagis koreni) is a species of polychaete worm that is classified within the Annelida phylum. It can be found in the waters around Europe including the North Sea, the Arctic Ocean, the Mediterranean Sea, the Atlantic Ocean, and the Adriatic Sea. This species is typically found submersed in sand in the neritic zone. The trumpet worm can reach an average length of about one inch and is typically light pink in color, with visible red veins and two pairs of red gills. This...

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...

The Pompeii worm (Alvinella pompejana) is a species of polychaete worm, or bristle worm that is only found in the Pacific Ocean. It resides at hydrothermal vents, making it an extremophile, and was first discovered French marine biologists of the coat of the Galapagos Islands in the 1980s. It was described by Lucien Laubier and Daniel Desbruyeres as a deep-sea polychaete that could withstand extreme amounts of heat. The Pompeii worm can reach an average length of up to five inches and is...

Hydroides norvegica

Hydroides norvegica is a species of worm that is classified within the Annelida phylum. This species is known as a tube-forming worm, because its builds tube-shaped reefs in order to shelter itself. Its range includes the waters of the Persian Gulf, the Red Sea, the Mediterranean Sea, the Atlantic Ocean, and the Indian Ocean.
