Bathed in an otherworldly purple glow, James Santiago points to a curled leaf at the base of a spinach plant. “This is an issue we saw all the time at the vertical farm where I worked in Virginia. We don't know exactly what's going on, but I think it has something to do with water stress, which is weird because the plants are growing in water.”

The energy that plants capture from sunlight through photosynthesis provides the source of nearly all of humanity’s food. Yet the process of photosynthesis has inefficiencies that limit crop productivity, especially in a rapidly changing world. A new review by University of Illinois scientists and collaborators reflects on how improving photosynthesis can bring us closer to food security.

The U.S. is largely self-sufficient in agricultural food production, supported by a well-developed storage and interstate trade system. However, extreme weather events put increasing pressure on agriculture, potentially impacting the country’s ability to provide food for its growing population and underscoring the importance of maintaining a resilient food supply chain. 

The ubiquitous plastic beverage bottle makes up about half of plastic waste collected for recycling in the U.S. Most recycled plastic is processed domestically, but a portion is traded overseas.

Open-access biological databases have long served as pillars for life science research, providing freely accessible data that drive discovery across fields like genetics, ecology, and neuroscience.

 Scientists have long known that Black women with estrogen-receptor positive breast cancer and those who live in disadvantaged neighborhoods often have more aggressive forms of the disease and poorer survival rates. However, the underlying factors that link these outcomes with women’s living environments have remained unclear.

Agricultural producers and manufacturers often need information about crop attributes, from nutrient content to chemical composition, to make management decisions. In recent years, multispectral imaging has emerged as a useful tool for product analysis, but the required equipment is expensive. Standard RGB cameras are much more affordable, but their images show only visible attributes.

Chronic Wasting Disease, a prion protein disease that is fatal in elk, deer, and other cervids, has spread rapidly across the United States since it was first identified in 1967. CWD has now reached Idaho near the Oregon border, causing concern for the Columbian white-tailed deer, a rare subspecies found only in two regions in Oregon.

On a 2009 hike in the Huachuca Mountains of southeastern Arizona, a group of birders heard an otherworldly, ethereal bird song floating, flute-like, through the canyon. The hikers identified the singer as a brown-backed solitaire, recognizing immediately that the bird was very far from home.

Zoos and private collections teach, inspire, and connect people to animals they may never encounter in the wild. And, in some cases, those animals represent valuable ‘assurance populations’ — essentially, backups that could be used to revive critically endangered populations in their native ranges.
