New research will improve early warning of devastating megastorms
Scientific research will make it easier to predict the path of some of the world's most powerful storms, enabling communities to better protect themselves from severe flooding. A new study has found that land surface conditions frequently affect the direction and intensity of mesoscale convective systems after they have formed.

Safer, more comfortable soldier uniforms are in the works
Uniforms of U.S. Army soldiers must meet a long list of challenging requirements. They need to feel comfortable in all climates, be durable through multiple washings, resist fires and ward off insects, among other things. Existing fabrics don't check all of these boxes, so scientists have come up with a novel way of creating a flame-retardant, insect-repellent fabric that uses nontoxic substances.
