A peptide that inhibits virus transmission among ferrets may point to a promising treatment

A newly engineered peptide has been shown to prevent virus transmission among ferrets when given two days prior to co-housing with infected animals. The peptide's stability and effectiveness in reducing infection rates make it a promising candidate for developing an intranasal prophylaxis treatment against SARS-CoV-2 in humans.

Out of this world: U of I researchers measure photosynthesis from space

Researchers at the University of Illinois developed a model to accurately calculate GPP in bioenergy crops using satellite data. The SLOPE GPP product explains 85% of spatial and temporal variations in GPP, overcoming previous inefficiencies in image-based, time-based, and latency precision.

Role of diet in risk of colorectal cancer

A new study published in JAMA Network Open examined the association between diet and colorectal cancer risk. The research found that a diet high in processed foods and added sugars is linked to an increased risk of colorectal cancer.
