the standard C3 pathway. This CO2-concentrating mechanism allows plants in a hot and dry climate to take up CO2 at night and store it, and release it again inside bundle sheath cells during the day, thus solving the problem of how to maintain a high ...
Study helps explain why botulinum toxin is so deadly
...e investigator. "A major question is how the toxin enters
neurons," he says. The research was a close collaboration with Ray Stevens of Scripps, who crystallized the structure that forms when botulinum toxin links to the protein receptor on a nerve cell. "This is the first paper to show in atomic detail th...

the soil. Because it binds strongly to organic molecules, mercury is most prevalent in the top several inches of soil, where organic matter is concentrated. By comparing the mercury content of burned soil with that of unburned soil, the researchers c...
