...e year 2050. SoyFACE has added a unique element by introducing surface-level ozone, which also is rising. Ozone is toxic to plants. SoyFACE is the first facility in the world to test both the effects of future ozone and CO2 levels on crops in the open air. Older, closed-condition studies occurred in greenhouses,...For diseases, when it comes to sharing a home, only close relatives will do
...ules apply to disease-causing microbes. They tried introducing a sexually-transmitted disease of plants, called "anther smut," into hosts that were already infected, and found that strains are more likely to share a host if they are more closely related. In this way "pathogens seem to interact as we would," say...Origen publishes in Nature a robust and versatile method for creating transgenic chickens
...anging their commitment -- proved to be the key to introducing genetic elements into the chicken genome. As a result, we can now take transgene designs that work well in model systems and breed flocks of birds depositing therapeutic proteins in their eggs.

...produced no changes in their hiding behavior. But introducing plants changed larvae behavior under both day and night conditions. Six pots of three uninfested corn plants - plants that had never been grazed - were placed around the cups of larvae. After eight hours, about 20% more larvae went into hiding when t...Modeling head and neck cancers
...I) in epithelial cells of the oral cavity. By then introducing activating mutations in either H-ras or K-ras (two different isoforms of the Ras GTPase), the researchers were able to induce invasive HNSCC with 100% incidence.

...e. The researchers first tested their approach by introducing a gene for green fluorescent protein into human T cells, and using siRNA to inhibit that gene's expression, and dim its fluorescent glow. They then applied their approach to HALP, a gene naturally active in T cells. Dr. Finkel previously discovered ......d colleagues achieved HOXB4 overexpression through introducing an active copy of the gene into the cells. However, because HOXB4 protein is available in recombinant form (i.e. produced in cell culture, much like human insulin), it should be possible to treat HSCs directly with the protein, avoiding the potential...Open source and open medicine take centre stage at UN research symposium
