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.

3D model shows off the insides of a giant permafrost crater

Researchers from Skoltech and Russian Academy of Sciences have surveyed the newest known 30-meter deep gas blowout crater on the Yamal Peninsula, forming a 3D model to study its structure and composition. The 3D model reveals a unique underground cavity with an elliptical shape and a circular dome, providing clues about the crater's en...

How to improve gender equity in medicine

Addressing gender inequity requires a multi-pronged approach, including embedding equity principles in policies, communicating gender statistics, and championing structural change. Implementing flexible schedules, non-gendered parental leave, and career support will help realize equity in pay and opportunities for all.

Harnessing socially-distant molecular interactions for future computing

Researchers have discovered that individual molecules on a metal surface can interact with each other over large distances, potentially revolutionizing the field of computing. This phenomenon has significant implications for the development of new electronic and optoelectronic technologies based on organic molecules and 2D materials.

Groundwater recharge rates mapped for Africa

A recent study has quantified groundwater recharge rates across Africa using ground measurements, helping to identify the sustainability of water resources. The results show that approximately 2% of all groundwater storage is replenished in Africa every decade, and recharge can occur even in semi-arid areas.

Star employees get most of the credit - and blame

Research by Cornell University's ILR School found that collaborating with a star employee reduces non-star employees' credit and gains in professional status during successful collaborations. However, it can mitigate or outweigh the loss of professional status associated with collaborative failure.

Slow motion precursors give earthquakes the fast slip

Scientists at Cornell University have discovered a connection between slow-motion fault slips and fast earthquakes, finding that 'slow slips' precede dozens of large magnitude 7 earthquakes. These precursory slips are directly involved in starting the earthquake and migrate towards where the fast slip begins.
