Mice exposed to heat wave temperatures ate less and showed weakened immune responses to the virus.

Tiny insects carry the tomato spotted wilt virus, which causes infected plants to develop discolored ring-shape blotches.

Using his expertise in microbiology and bioinformatics, he is bringing a new understanding to microbial immune systems.

Dampening the immune response to stay up in the air may have helped bats become tolerant to viral infections.

Some of our resident viruses may be beneficial.

Diverse viruses can be found commingling with human and bacteria cells in and on people’s bodies. Scientists are just beginning to understand how these viruses help and when they can turn pathogenic.
