Copying Nature in the Lab
Successful total synthesis of muricatetrocin -- a potential new cancer-fighting agent Muricatetrocin is the name of a natural substance that may someday gain important victories against certain cancers of the prostate, pancreas, and lungs. It was discovered in the leaves of Rollina mucosa, a magnolia-like plant of the tropical rainforest,... view more... (2000-10-12)
Natural-born divers and the molecular traces of evolution
An aquatic lifestyle imposes serious demands for the organism, and this is true even for the tiniest molecules that form our body. view more (2009-06-29)
Study of flower color shows evolution in action
Scientists at UC Santa Barbara have zeroed in on the genes responsible for changing flower color, an area of research that began with Gregor Mendel's studies of the garden pea in the 1850's. view more (2009-06-30)

Obesity genetics
New evidence that genetics plays a key role in obesity is published today in the International Journal of Bioinformatics Research and Applications. The findings relate to the genetics of modern Pima Indians who have an unusually high rate of obesity but could be extrapolated to all people. view more (2007-10-16)
Inconspicuous leaf beetles reveal environment's role in formation of new species
Unnoticed by the nearby residents of St. Johnsbury, Vermont, tiny leaf beetles that flit among the maple and willow trees in the area have just provided some of the clearest evidence yet that environmental factors play a major role in the formation of new species. view more (2009-11-02)
`Glowing` technique could detect river pollution
New technology used to analyse dissolved organic matter in river water could also help scientists detect and monitor pollution, according to a new research published in the journal Hydrological Processes (1). Dissolved organic matter is found in all river water, and can come from both a natural source such as the soil, as well as human sources... view more... (2002-10-07)

New company learns from spider`s ability to spin
A new spin-out from Oxford University, Spinox, is aiming to devise novel ways to copy spiders` ability to spin silks. The new silks may be used for sutures or woven material for surgical implants, protective clothing and in sports equipment. Spinox has been set up to fully develop a spinning process to create high performance fibres from natural... view more... (2002-03-07)
Adverse reactions of natural health products/drugs under-reported, study shows
