Researchers have developed soft yet durable 3D-printed materials that glow in response to mechanical stress, such as compression, stretching or twisting. The materials derive their luminescence from single-celled algae known as dinoflagellates, which are embedded within the materials. The work was inspired by the bioluminescent waves caused by dinoflagellates during red tide events at San Diego’s beaches.

For hundreds of years, business owners engaged in New Jersey’s commercial fisheries industry have weathered adversity, from coastal storms to species shifts. Recognizing this resilience, and acknowledging the challenges posed by global climate change, Rutgers scientists have come to their assistance. One of the results of recent efforts is a guide that researchers have developed for marine businesses, A Resilience Checklist for New Jersey’s Commercial Fishing Industry.

Genetic evidence looked at how salmon were affected by two major culvert replacements near the city of Bellingham. One project, a major upgrade under Interstate-5, had a big impact, while the other old culvert may have been less of a barrier to fish. Researchers at the University of Washington and NOAA are studying the use of eDNA in future environmental impact reporting.

Under normal conditions, the floating macroalgae Sargassum spp. provide habitat for hundreds of types of organisms. However, the Great Atlantic Sargassum Belt (GASB) that emerged in 2011 has since then caused unprecedented inundations of this brown seaweed on Caribbean coastlines, with harmful effects on ecosystems while posing challenges to regional economies and tourism, and concerns for respiratory and other human health issues.

Recent conservation efforts have proven effective at controlling wild pig populations in the Southeastern United States, according to new research from the University of Georgia’s Savannah River Ecology Laboratory and Warnell School of Forestry and Natural Resources. Within 24 months of the start of control efforts in the study area located around the Savannah River Site in Aiken, South Carolina, researchers found a reduction of about 70% in relative abundance of pigs and a corresponding decline in environmental rooting damage of about 99%.

•New Michigan State University research published in the journal Proceedings of the National Academy of Sciences shows that plants such as oak and poplar trees will emit more of a compound called isoprene as global temperatures climb. •Isoprene from plants represents the highest flux of hydrocarbons to the atmosphere behind methane. •Although isoprene isn’t inherently bad — it actually helps plants better tolerate insect pests and high temperatures — it can worsen air pollution by reacting with nitrogen oxides from automobiles and coal-fired power plants. •The new publication can help us better understand, predict and potentially mitigate the effects of increased isoprene emission as the planet warms.

This asynchronous beating comes from how the flight muscles interact with the physics of the insect’s springy exoskeleton. This decoupling of neural commands and muscle contractions is common in only four distinct insect groups. For years, scientists assumed these four groups evolved these ultrafast wingbeats separately, but research from the Georgia Institute of Technology and the University of California, San Diego (UC San Diego) shows that they evolved from a single common ancestor. This discovery demonstrates evolution has repeatedly turned on and off this particular mode of flight. The researchers developed physics models and robotics to test how these transitions could occur.

For the first time, big data and artificial intelligence (AI) are being used to model hidden patterns in nature, not just for one bird species, but for entire ecological communities across continents. And the models follow each species’ full annual life cycle, from breeding to fall migration to nonbreeding grounds, and back north again during spring migration.

Plants have highly evolved mechanisms to shed or drop organs (abscission) in response to environmental or developmental cues. It’s why you have to rake leaves in the Fall! But in agriculture, the natural shedding of flowers or seeds is detrimental, and cereal crops with abscission-inhibiting mutations in certain genes, like SHATTERING1, have been bred to dramatically increase yield. Using Crispr gene editing and detailed analyses, Yu et al. show for the first time some mechanistic features of abscission in the grasses, including the role of the plant hormone auxin.

A new study, which combines satellite thermal and in situ warming experiment data from across the world’s tropical forests, looks at the variation of leaf temperatures within forest canopies. The data collected revealed that a small percentage of tropical leaves are already reaching, and occasionally exceeding, the temperatures at which they can no longer function—suggesting that as climate change continues, entire canopies could die, eliminating a key regulator of Earth’s climate and putting the world’s biodiversity at risk.
