Marine biologists of the University of Vienna publish in PNAS Marine shallow water sandy bottoms on the surface appear desert-like and empty, but in the interstitial space between the sand grains a diverse fauna flourishes. In addition to bacteria and protozoa numerous animal phyla have been found here, some only here. One of the strangest members of this interstitial fauna is Paracatenula, a several millimeters long, mouth and gut-less flatworm, which is found from tropical oceans to the...

A species of algae long known to associate with spotted salamanders has been discovered to live inside the cells of developing embryos, say scientists from the U.S. and Canada, who report their findings in this week's Proceedings of the National Academy of Sciences.This is the first known example of a eukaryotic algae living stably inside the cells of any vertebrate."It raises the possibility that more animal/algae symbioses exist that we are not aware of," said Indiana University Bloomington...

The evolution of complex life is strictly dependent on mitochondria, the tiny power stations found in all complex cells, according to a new study by Dr Nick Lane, from UCL (University College London), and Dr William Martin, from the University of Dusseldorf. "The underlying principles are universal. Energy is vital, even in the realm of evolutionary inventions," said Dr Lane, UCL Department of Genetics, Evolution and Environment. "Even aliens will need mitochondria." For 70 years scientists...

Researchers at the Sven Lov©n Centre for Marine Sciences at the University of Gothenburg have discovered a brand new species of bacterium found only in the Gullmarsfjord north of Gothenburg. The bacterium has been named Endoxenoturbella lov©nii to honor the newly founded marine research center. Researcher Matthias Obst from the Department of Zoology is one of many marine scientists based at the Sven Lov©n Centre for Marine Sciences, a new institute owned by the University of...

The human gut is a breeding ground - in a good way - for a wide variety of bacteria, according to a new study. An international effort to catalog millions of non-human genes found inside people, found more than 170 different bacteria species living in the average person's digestive system. The study also found that people with inflammatory bowel disease had fewer unique species than healthier people. More than 99 percent of all the different gene types in the human body are not even human,...

A study by scientists from the University of Valencia sheds new light on how the cockroach organism works. A research team from the Cavanilles Institute for Biodiversity and Evolutionary Biology, led by professors Amparo Latorre and Andr©s Moya, has shown why the German cockroach (Blatella germanica) eliminates excess nitrogen by excreting ammonia, in contrast to most terrestrial insects that commonly produce uric acid as a waste compound. The research is published November 13 in the...

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...

Finding could lead to new understanding of substance harmful in kidney disease and other human diseases What life form can use materials as nutrients that we, and most other animals, would consider waste products? None other than the giant cockroaches that infest sewer systems and erupt from people's bathtub drains, according to scientists Nancy Moran and Zakee Sabree of the University of Arizona, and Srinivas Kambhampati of Kansas State University. The researchers published their results in...

MOFFETT FIELD, Calif., Aug. 19 /PRNewswire-USNewswire/ -- Humans might not be walking on Earth today if not for the ancient fusing of two microscopic, single-celled organisms called prokaryotes, NASA-funded research has found. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) By comparing proteins present in more than 3000 different prokaryotes -- a type of single-celled organism without a nucleus -- molecular biologist James A. Lake from the University of California at Los...

A NASA-funded study suggests humans might not exist today if not for the ancient fusing of two microscopic, single-celled organisms called prokaryotes. Biologist James Lake of the UCLA Center for Astrobiology compared proteins present in more than 3,000 different prokaryotes -- a type of single-celled organism without a nucleus -- and discovered two major classes of relatively simple microbes fused together more than 2.5 billion years ago. That endosymbiosis, or merging of two cells, he said,...

Aphids or greenfly, plant lice (superfamily Aphidoidea) are small plant-feeding insects (1 to 10 mm). Of the 4,000 species of known aphids (distributed in 10 families), around 250 are serious pests for agriculture and forestry as well as an annoyance for gardeners. Natural predators include ladybirds, hoverfly larvae and lacewings. Aphids have two compound eyes and two ocular tubercles made up of 3 lenses, each of which is located behind and above the compound eyes. They have 2 tarsal...
