Discarded human debris threatens global biodiversity
Discarded human debris is encouraging colonization of exotic marine animals in the world`s oceans and threatening global biodiversity, particularly in the Southern Ocean. The findings, reported in this week`s NATURE, are based on a 10-year study of human litter (mostly plastic) washed ashore on 30 remote islands around the globe, from the Arctic... view more...

Ducks go quackers for dishy drakes
Good-looking males produce healthiest families Every parent wants to ensure their offspring get the best start in life, but it seems that offspring of attractive parents might be getting a better start than others. Studies of mallard ducks carried out by scientists based at the University of Cambridge show that females are laying bigger eggs for... view more... (2000-02-29)
Old before their time? Aging in flies under natural vs. laboratory conditions
Evolutionary studies of aging typically utilize small, short-lived animals (insects, worms, mice) under benign conditions - constant temperature and humidity, no parasites, superabundant food - in the laboratory. Oddly enough, very little is known about aging in such animals in their harsh, stressful natural environments. Could it be that these... view more... (2008-09-08)
Hidden sponges determine coral reef's nutrient cycle
Marine organisms hidden in caves, such as sponges, play an extremely important role in the nutrient cycle of coral reefs. view more (2005-09-15)
Almost 7 million pregnant in sub-Saharan Africa infected with hookworms; at risk of anaemia
A study published today in the open-access journal PLoS Neglected Tropical Diseases reveals that between a quarter and a third of pregnant women in sub-Saharan Africa, or almost 7 million, are infected with hookworms and at increased risk of developing anaemia. view more (2008-09-18)
Short RNAs show a long history
MicroRNAs, the tiny molecules that fine-tune gene expression, were first discovered in 1993. But it turns out they've been around for a billion years. view more (2008-10-02)
Gene exchange common among sex-manipulating bacteria
Certain bacteria have learned to manipulate the proportion of females and males in insect populations. Now Uppsala University researchers have mapped the entire genome of a bacterium that infects a close relative of the fruit fly. view more (2009-03-26)
Possible new hope for crops battling parasitic infection
Scientists from Ghent University and VIB (The Flemisch Institute for Biotechnology) have demonstrated how nematodes, also known as roundworms, manipulate the transport of the plant hormone auxin in order to force the plant to produce food for them. view more (2009-01-16)
Less trouble at mill, thanks to earthworms
Waste from the textiles industry could with the assistance of earthworms and some animal manure become a rich compost for agriculture, according to a report in the International Journal of Environment and Pollution. view more (2009-07-16)
Fossilised Embryos - 500 Million Years Old
Evidence from fossilised embryos of worm-like creatures that lived 500 million years ago shows that embryos developed then in much the same way as their living relatives do today. The implications of this remarkable discovery, reported in this week's issue of Nature, is that embryological processes that occur today must have been established very... view more... (2004-01-12)
Discovery of a unique symbiosis between bacteria and a marine worm
Dr. Nicole Dubilier, a scientist in the Molecular Ecology research group of Dr. Rudolf Amann at the Max Planck Institute of Marine Microbiology in Bremen, and her colleagues have discovered a unique symbiosis between bacteria and a marine worm, described in the journal Nature, issue May 17th 2001. The term symbiosis typically evokes an image of... view more... (2001-05-17)
Learning the language of DNA
An international consortium of scientists, including a team from The University of Queensland's Institute for Molecular Bioscience (IMB), is a step closer to the next generation of treatments to combat disease, after publishing a comprehensive analysis of the human and mouse transcriptomes. view more (2006-05-03)
The clustering of Hox genes, involved in the determination of body segments, is not necessary for their proper function
The Hox genes (also known as homeotic genes) play a crucial role in the development of animals, being involved in the determination of segment identity along the body axis. These genes were discovered in the fruit fly Drosophila melanogaster 90 years ago and have been found later in all animals, including humans. The Hox genes are arranged in the... view more...

U of M study finds new insight on therapy for a devastating parasitic disease
University of Minnesota Medical School researchers have discovered an important new insight into how a commonly prescribed drug may work to treat those infected by a parasitic flatworm. view more (2009-06-24)
Wales hosts world workshop for better conservation
These special scientists, known as taxonomists are members of BioNET International, the brainchild of Professor Tecwyn Jones of Cardiff University. They are skilled in the science concerned with identifying, classifying and understanding the relationships of the myriad species of organisms which form the Earth's biodiversity. view more (1999-08-16)
Stem cell protein offers a new cancer target
A protein abundant in embryonic stem cells is now shown to be important in cancer, and offers a possible new target for drug development, report researchers from the Stem Cell Program at Children's Hospital Boston. view more (2009-06-02)
Viral hitchhiker inhibits Wolbachia bacteria's ability to proliferate
Scientists studying the widespread symbiotic bacteria Wolbachia have long been interested in its ability to proliferate. view more (2006-05-19)
Researchers go underground to reveal 850 new species
Australian researchers have discovered a huge number of new species of invertebrate animals living in underground water, caves and "micro-caverns" amid the harsh conditions of the Australian outback. view more (2009-09-28)
To swim or to crawl: For the worm it's a no brainer
A study at the University of Leeds has shown, for the first time, that C. elegans worms crawl and swim using the same gait, overturning the widely accepted belief that these two behaviours are completely different. view more (2009-03-31)
Logging changed ecological balance for monkeys, damaged health
Twenty-eight years after intense selective logging stopped in the region now known as Uganda's Kibale National Park, the red-tailed guenon (Cercophithecus ascanius) is a primate still in decline. view more (2005-06-15)
