Nevertheless, while the climate-velocity concept is still crude, it's promising enough that Ackerly is collaborating with an organization called the Bay Area Open Space Council on habitat conservation strategies in central California.

"What we bring," says Ackerly, "is the ability to think about how topography might affect those decisions...
...Further research revealed that the same proteins also help cells resist illnesses such as West Nile virus, dengue fever, and yellow fever. But the proteins did not seem to be effective in defending cells from HIV or hepatitis...
...drug that increases the presence of IFITM proteins in humans without provoking negative side effects may be an effective means of preventing influenza. Another area of potential research is the possibility of inserting the IFITM genes into the genomes of animals like swine and poultry—the strains of influenza most dangerous to humans typically emerge from these animals...
