Complex illnesses are not caused by one gene but groups of genes. The number of gene combinations is too enormous to analyze comprehensively. New AI model focuses on gene expression changes to identify key genes and their collective influence on disease.

As solar energy becomes more affordable and widespread, farmland has emerged as a prime location for large-scale solar development. But with this expansion comes a persistent question: Do nearby property values suffer when solar farms move in? In a new paper published in the Proceedings of the National Academy of Sciences, researchers in Virginia Tech’s Department of Agricultural and Applied Economics in the College of Agriculture and Life Sciences looked at millions of property sales and thousands of commercial solar sites to shed some light on one of the mostly commonly cited downsides of large-scale solar adoption. 

A study in Science Advances that describes a new soft robotic system was co-led by Harvard Professor L. Mahadevan in collaboration with Professor Ho-Young Kim at Seoul National University. Their work paves new directions for future, low-power swarm robotics.

The new robots, called link-bots, are comprised of centimeter-scale, 3D-printed particles strung into V-shaped chains via notched links and are capable of coordinated, life-like movements without any embedded power or control systems. 

Mycorrhizal fungi help regulate Earth’s climate and ecosystems by forming underground networks that provide plants with essential nutrients, while drawing carbon deep into soils. Scientists and conservationists have been racing to find ways to protect these underground fungi, but they keep finding dark taxa – species that are known only by their DNA sequences that can’t be linked to named or described species.

The Center for Bioenergy Innovation, or CBI, at the Department of Energy’s Oak Ridge National Laboratory has promoted Melissa Cregger and Carrie Eckert to serve as chief science officers, advancing the center’s mission of innovations for new domestic biofuels, chemicals and materials.
