It takes cellular teamwork to heal the intestine

A meticulous single-cell analytical approach to study the repair process of rotavirus-caused injury in an animal model revealed that the damaged epithelium contains a variety of cell types involved in repairing it through broad coordinated responses that ultimately heal the damaged tissue.

Comparing photosynthetic differences between wild and domesticated rice

Millions of people in Asia are dependent on rice as a food source. Believed to have been domesticated as early as 6000 BCE, rice is an important source of calories globally. In a new study from the RIPE project, researchers compared domesticated rice to its wild counterparts to understand the differences in their photosynthetic capabilities. The results can help improve future rice productivity.

History of insect invasions offers insight into the future

Over the past two centuries, thousands of non-native insects have hitchhiked to the United States in packing material, on live plants, and in passenger baggage. Scientists with two U.S. Department of Agriculture (USDA) agencies and their partners used the history of live plant imports and invasion by a common group of insects to estimate the rate at which new insects are arriving and how many new...

History of insect invasions offer insight into the future

Results from a recently published study suggest that efforts to reduce biological hitchhiking on live plant imports, often referred to as 'biosecurity,' are working. However, more than a century of invasion by Hemiptera insects also suggests that increased trade might offset the effects of improved biosecurity. As many as 25 percent of invading Hemiptera insects may have yet to be detected in the...
