UTA mathematicians to improve curricula for future high school mathematics teachers
Mathematicians at The University of Texas at Arlington are conducting research to refine and supplement curriculum materials used in college mathematics courses designed for students who plan to become high school math teachers. The project specifically aims to enhance materials currently used in UTeach Arlington, UTA's version of the highly successful science and mathematics secondary teacher preparation program which has been replicated at 43 universities across the United States.

Flowers critical link to bacteria transmission in wild bees
A team of researchers, including several from the University of California, Riverside, have found that flowers are a hot spot of transmission of bacteria that end up in the microbiome of wild bees.

Farming adaptations needed to combat climate change to impact crop yields in 2050
As the globe continues to spin toward a future with higher temperatures, crop yields will likely decrease if farmers do not adapt to new management or technology practices. Establishing new strategies is particularly difficult for sorghum farmers in West Africa where seed varieties and fertilizer are scarce, while drought and unpredictable rainfall are prevalent. Using more heat-resistant sorghum varieties may yield the most benefits, research shows.

OU study demonstrates seasonality of bird migration in response to environmental cues
A University of Oklahoma study demonstrates for the first time that remote sensing data from weather surveillance radar and on-the-ground data from the eBird citizen science database both yield robust indices of migration timing, also known as migration phenology. These indices can now be used to address the critical gap in our knowledge regarding the cues that migrants use for fine tuning their migration timing in response to climate.

Nature Materials
Researchers design solids that control heat with spinning superatoms
Superatom crystals are periodic arrangements of C60 fullerenes and similarly sized inorganic molecular clusters. There are two nearly identical formations, one with rotating (i.e. orientationally disordered) C60s and low conductivity, and one with fixed C60s and high thermal conductivity. Superatom crystals represent a new class of materials with potential for applications in sustainable energy generation, energy storage, and nanoelectronics. Additional research could lead to controlling rotational disorder in new kinds of thermal switches and transistors.

Friends help friends on Facebook feel better
Personal interactions on Facebook can have a major impact on a person's feelings of well-being and satisfaction with life just as much as getting married or having a baby, a new study by Carnegie Mellon University and Facebook researchers shows. What really makes people feel good is when those they know and care about write personalized posts or comments.

Location matters in the self-assembly of nanoclusters
Scientists at Iowa State University have developed a new formulation that helps to explain the self-assembly of atoms into nanoclusters and to advance the scientific understanding of related nanotechnologies. Their research offers a theoretical framework to explain the relationship between the distribution of 'capture zones,' the regions that surround the nanoscale 'islands' formed by deposition on surfaces, and the underlying nucleation or formation process.

Super-resolution microscope builds 3-D images by mapping negative space
Scientists have demonstrated a method for making 3-D images of structures in biological material under natural conditions at a much higher resolution than other existing methods. The method may help shed light on how cells communicate with one another and provide important insights for engineers working to develop artificial organs such as skin or heart tissue.

During drought, dry air can stress plants more than dry soil
Newly published research finds that low relative humidity in the atmosphere is a significant, growing and often under-appreciated cause of plant stress in hot, dry weather conditions. The finding suggests that models used to gauge the impact of drought on ecosystems should be refined to more accurately account for the role of low atmospheric humidity.

Scientists from Rice University, Stanford University and the Carnegie Institution for Science said data from one of the world's longest-running climate-change experiments show that California grasslands will become less productive if the temperature or precipitation increases substantially above average conditions from the past 40 years.

Grassland tuned to present suffers in a warmer future
One of the longest-running, most comprehensive climate change experiments produced some surprises. Researchers subjected grassland ecosystems to sixteen possible future climates and measured ecosystem performance and sustainability. The study covered 17 years of plant growth, an important bellwether of ecosystem health. Plant growth varied tremendously from year to year; it peaked under conditions near the average over the last several decades. As conditions moved away from the averages, as happens with climate change, plant growth fell.

'Materials that compute' advances as Pitt engineers demonstrate pattern recognition
The potential to develop 'materials that compute' has taken another leap at the University of Pittsburgh's Swanson School of Engineering, where researchers for the first time have demonstrated that the material can be designed to recognize simple patterns. This responsive, hybrid material, powered by its own chemical reactions, could one day be integrated into clothing and used to monitor the human body, or developed as a skin for 'squishy' robots.

Crop domestication is a balancing act
The ancestors of leaf-cutter ants swapped a hunter-gatherer lifestyle for a bucolic existence on small-scale subsistence farms. A new study at the Smithsonian Tropical Research Institute in Panama revealed that living relatives of the earliest fungus-farming ants still have not domesticated their crop, a challenge also faced by early human farmers.

Pitt chemical engineer receives NSF grant to study self-assembly of large-scale particles
'Fabricating the self-assembly of larger particles had been done a handful of times before we started trying it, but we've pushed the possibilities a lot further,' said McCarthy. 'Other researchers noticed the phenomenon occurring empirically, but we are trying to formalize it. We are working with particles that are at least 100 times bigger than anything that has been done before.'
