UNIVERSITY PARK, Pa. The presence of high salt and nitrogen concentrations in high- tunnel soils may make it more challenging to rebuild a healthy soil microbiome following a soil-clearing event, according to microbial ecologists in Penn State’s College of Agricultural Sciences.
Their research findings have important implications for soil fertility, and by extension, crop health and yield, explained Laura Kaminsky, a doctoral candidate in plant pathology, who led the investigation under the guidance of Terrence Bell, assistant professor of phytobiomes.

As any cook knows, some liquids mix well with each other, but others do not. For example, when a tablespoon of vinegar is poured into water, a brief stir suffices to thoroughly combine the two liquids. However, a tablespoon of oil poured into water will coalesce into droplets that no amount of stirring can dissolve. The physics that governs the mixing of liquids is not limited to mixing bowls; it also affects the behavior of things inside cells. It s been known for several years that some proteins behave like liquids, and that some liquid-like proteins don t mix together. However, very little is

How Your Brain Decides To Put in Effort
Researchers have clear visual evidence that a region of the human brain known as the ventral striatum kicks in during decision-making to weigh the costs versus the benefits of making a physical effort.
The research gives the first detailed view of ventral striatum activity during three phases of effort-based decision-making the anticipation of initiating an effort, the actual execution of the effort, and the reward, or outcome, of the effort.

As aircraft become more electric, engines become more efficient and spacecraft seek to conquer new frontiers, the aerospace and defense industry needs fresh ideas from younger generations that grew up with a passion for sustainability and innovative technologies.
Through the annual 20 Twenties program, the Aviation Week Network and the American Institute of Aeronautics and Astronautics (AIAA) recognize young, rising stars within the industry. Top students working to solve aerospace challenges are nominated by universities around the world, and a judging panel comprised of hiring managers, engineers and academics selects 20 exceptional winners. Nominees are evaluated based on academic performance, civic contribution and the value of their research or design projects.
