Climate change complicates plant diseases of the future (June 26, 2010) -- Human-driven changes in the earth's atmospheric composition are likely to alter plant diseases of the future. Researchers are studying the impact of elevated carbon dioxide, elevated ozone and higher atmospheric temperatures on plant diseases that could challenge crops in these changing conditions. ... > full story
Pleasing to the eye: Even brooding female birds are sensitive to visual stimulation (June 26, 2010) -- In a breeding experiment with Houbara bustards -- a North African bird species with a very distinctive courtship behavior -- scientists have concluded that visual stimulation from attractive males of the same species positively affects brooding females, improving offspring growth. ... > full story
Scientists create 3-D models of whole mouse organs (June 26, 2010) -- Engineers have for the first time created 3-D models of whole intact mouse organs, a feat they accomplished using fluorescence microscopy. ... > full storyAggressive action to reduce soot emissions needed to meet climate change goals, experts say (June 26, 2010) -- Without aggressive action to reduce soot emissions, the time table for carbon dioxide emission reductions may need to be significantly accelerated in order to achieve international climate policy goals such as those set forth in last December's Copenhagen Accord, according to a new study. ... > full story
Virus works with gene to cause Crohn's-like illness (June 25, 2010) -- Scientists have shown that a specific virus can interact with a mutation in the host's genes to trigger disease. The observation may help explain why many people with disease risk genes do not actually develop disease. ... > full story
Four-leaf clover gives up its secrets (June 25, 2010) -- Ending a period of "bad luck" for clover researchers, scientists report finding the gene that turns ordinary three-leaf clovers into the coveted four-leaf types. Masked by the three-leaf gene and strongly influenced by environmental condition, molecular markers now make it possible to detect the presence of the gene for four-leaves and for breeders to work with it. ... > full story
Ecological change in the abyss: The Amperima event (June 25, 2010) -- Even in the dark abyss of the deep ocean animal communities can undergo rapid, widespread and radical changes. Scientists are monitoring these changes and understanding the mechanisms responsible. ... > full storySmall amount of common preservative increases toxins from harmful bacteria in food, study finds (June 25, 2010) -- In response to consumer demand for more natural food, the food industry has reduced the amount of preservatives in food over recent years. A common preservative is acetic acid, which is used to stop bacterial growth in dressings, sauces, cheese and pickles. However, new research shows that a small amount of acetic acid does not have the intended effect, but rather the opposite -- it increases the amount of toxin from the harmful bacteria in the food. ... > full story
NASA radar images show how Mexico quake deformed Earth (June 25, 2010) -- Minerals in northern Mars craters seen by two orbiters suggest that a phase in Mars' early history with conditions favorable to life occurred globally, not just in the south. ... > full story
Biomedical scientist concerned about effects of oil spill on human health (June 25, 2010) -- A biomedical researcher says that some of the same chemicals found in diesel fumes and cigarette smoke are also found in the tar balls produced as a result of the oil spill, and he is worried about the effect they will have on the health of clean-up workers and wildlife. ... > full storyFreshwater fish eyes: Great home for parasites (June 25, 2010) -- The limited immune response in the eyes of freshwater fishes has created a great home for parasites, according to new research. The study provides a lens into the evolutionary world of the larval flukes that parasitize Canadian fish. ... > full story
