New Cotton Gauze Stops Bleeding Fast

Uncontrolled bleeding is the main cause of preventable death in people who experience traumatic injury. This can happen in 5 to 10 minutes if severe blood loss from the injury site isn’t slowed or stopped.

Now, Agricultural Research Service (ARS) scientists in New Orleans, Louisiana, have helped develop a nonwoven cotton gauze that quickly stanches bleeding and promotes healing.

REE Gives the Gift of Agricultural Research and Innovation in 2018

Like many of you, I bask in the excitement of the holidays—wrapping gifts, planning holiday dinners, and spending time with loved ones. However, this month also means the end of the year is near, ushering in a time of reflection and anticipation. In USDA’s Research, Education, and Economics (REE) mission area, this time of year serves as neither a beginning nor an end. For us, it is a continuation of the scientific research needed to solve the agricultural challenges ahead.

The Name, the Pin, and the Bee

She leans over her dead subject and deftly pushes a pin through its body, securing it to the foam below. To be clear, this is not about a morgue or a serial killer. This is about taxonomy, or the science of identifying, classifying, and naming organisms. The woman in question is a scientist, and her pinned subject is a bee.

USDA’s Role in Combatting Antimicrobial Resistance

Scientists from USDA developed the tools to mass produce penicillin, which was used for treating wounded soldiers over 70 years ago during World War II. Antibiotics are still important in treating microbial infection in humans, animals, and plants. However, microbes can develop resistance to some antibiotics, making them less effective. USDA agencies continue to work on numerous issues related to antibiotics and antimicrobial resistance (AMR).

The Makings of a Good Sweet Potato

Sweet potatoes, which are native to the Americas, sustained our founding pioneers with beneficial nutrients like beta carotene, calcium, fiber, and a host of vitamins. No wonder it’s a holiday favorite, especially during Thanksgiving. But what makes a good sweet potato?

USDA Research Progress Towards Global Food Security

Most of us living in the United States are fortunate enough not to wonder where our next meal will come from. Yet across the globe, at least some time during the year, nearly 800 million people do. Not having access to stable and nutritious food sources – or food insecurity — negatively impacts people’s lives. Food security, on the other hand, means access by all people at all times to enough food for an active, healthy life.
