Cougar predation key to ecosystem health

...declining biodiversity. This "trophic cascade" of environmental degradation, all linked to the decline of a major predator, has been shown in a new study to affect a broad range of terrestrial and aquatic species, according to scientists from Oregon State University. The research was just published ...

Solvent exposure linked to birth defects in babies of male painters

...niversity of Alberta professor of occupational and environmental health, who co-authored the study with researchers from Radboud University Nijmegen Medical Centre in the Netherlands. "This is the first time we have good exposure data in such a study, but more robust investigations are needed to guide policy-maker...

Biotech cotton provides same yield with fewer pesticides

...- we must look at those all together to assess the environmental impacts of transgenics," Carrière said. "The take-home message is that transgenic crops are very promising for reducing the impact of agriculture, but we need to study how they're integrated into the way we do agriculture. It depends on how the produ...

Scientists solve 30-year-old mystery of mutant mouse's kidney woes

...ilure and death. Scientists suspect a variety of environmental and genetic factors contribute to fetal hydronephrosis. However, they frequently cannot tie it to any causative factors, making it difficult to determine how normal molecular and cellular processes in kidney development break down in infants affected...

Scientists' cell discovery unearths evolutionary clues

... multi-cellular structures in response to changing environmental conditions. Previously, there was almost no molecular data for social amoeba ?Dictyostelia ?which are a hugely diverse and ancient group. Social amoebas are a group of organisms with a genetic diversity that is greater than that of fungi and simil...

Gut reaction: Researchers define the colon's genome

... TIGR and elsewhere have recently scooped up whole environmental samples, from soil to sea, to study the diverse ge...amining how whole ecosystems of genomes respond to environmental perturbations--and, in the case of humans, how microbial ecosystems contribute to health and disease...

Major cancer study aims to identify protein markers for early-stage disease

Gibson, PhD, a professor and di...

Epstein-Barr virus might kick-start multiple sclerosis

...The susceptibility to acquire MS is inherited, but environmental insults such as viral infections are thought to trigger the disease, and Epstein-Barr virus is one of the leading candidate triggers," said first author Jan Lünemann, a neurologist and immunologist at The Rockefeller University in New York. "Epstein-...

Gene therapy prevents the onset of diabetic symptoms in mice

Acid rain, the environmental consequence of burning fossil fuels, running factories and driving cars, has altered soils and reduced the number of sugar maple trees growing in the Northeast, according to a new study led by Cornell University researchers. The sugar maple is the ...

Acid rain causing decline in sugar maples, say researchers

Acid rain, the environmental consequence of burning fossil fuels, running factories and driving cars, has altered soils and reduced the number of sugar maple trees growing in the Northeast, according to a new study led by Cornell University researchers. The sugar maple is the ...

Eminent inventor of DNA fingerprinting gains new recognition

...Jeffreys has concentrated on genetic mutations and environmental factors. He is, for example, studying how irradiation may have caused genetic mutations in families from Chernobyl."Luton-born Sir Alec has formerly studied in Amsterdam as a postdoctoral fellow in the laboratory of Piet Borst, a 1994 Heineken prizew...

No-mow grass may be coming to your yard soon

In recent years, through the methods of genetic engineering, more precise methods for altering industrial plant strains have c...

Race to halt global amphibian crisis boosted by rediscovery of endangered Colombian frogs

... extinction crisis is wiping out so many important environmental indicator species, such as Atelopus frogs, before our very eyes, so this is a real boost for conservation efforts." The Alliance for Zero Extinction ( www.zeroextinction.org ) issued a report in December 2005 that pinpointed 595 sites around the wo...

Potato blight pathogenicity explained by genome plasticity

...Understanding genome plasticity as a mechanism for environmental response and ecological adaptation in pathogenic organisms has important implications. "The efforts of plant breeders to obtain resistant varieties by introducing R genes, either by classical breeding or by genetic modification, may be a waste of ...
