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.

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?

Vertical Farming for the Future

Imagine walking into your local grocery story on a frigid January day to pick up freshly harvested lettuce, fragrant basil, juicy sweet strawberries, and ripe red tomatoes – all of which were harvested at a local farm only hours before you’d arrived. You might be imagining buying that fresh produce from vertical farms where farmers can grow indoors year-round by controlling light, temperature, water, and oftentimes carbon dioxide levels as well. Generally, fresh produce grown in vertical farms travels only a few miles to reach grocery store shelves compared to conventional produce, which can travel thousands of miles by truck or plane.
