An international team of researchers has discovered that previously observed variations in brightness of a free-floating planetary-mass object known as SIMP 0136 must be the result of a complex combination of atmospheric factors, and cannot be explained by clouds alone.

A research team has identified a new species of tiger swallowtail butterfly living in eastern parts of North America. In their study, published in the journal ZooKeys, Julian Dupuis, B. Christian Schmidt, Charles J. DeRoller and Xi Wang captured and compared samples of Papilio glaucus and Papilio canadensis hybrids and compared them with both species,…
Two new studies show how a seeming tangle of DNA is actually organized into a structure that coordinates thousands of genes to form a sperm cell. The work, published as two papers in Nature Structural & Molecular Biology, could improve treatment for fertility problems and developmental disorders. Two new studies show how a seeming tangle of…
The amount of nitrogen fertilizer needed to maximize the profitability of corn production in the Midwest has been increasing by about 1.2% per year for the past three decades, according to new Iowa State University research.

When the COVID-19 pandemic first began, we saw how quickly the SARS-CoV-2 virus evolved. New variants emerged with mutations that increased transmissibility or helped the virus evade our immune systems. But predicting which mutations would be most successful—and why—has remained a challenge. When the COVID-19 pandemic first began, we saw how quickly the SARS-CoV-2 virus evolved….
When wind or other disturbances detach winged maple seeds called samaras from their parent tree, they spin through the air—and can even spin when it’s raining. Impacts by high-speed raindrops only briefly interrupt the seed’s spinning because the seed can shed the drop rapidly and restart its spinning in less time than it takes to…
The recent volatility of egg prices in the United States has been a hot topic. Media coverage has consistently made the connection between supply problems and virulent strains of avian flu that has been afflicting poultry birds since 2022. The recent volatility of egg prices in the United States has been a hot topic. Media coverage…
