From glaciers to rainfall: Understanding unexpected rain

In 2018, a group of students from the Universities of Innsbruck, Austria, and Hamburg, Germany, were on a research excursion close to the village of Llupa in the Rio Santa valley in the Peruvian Andes. While they were busy installing a weather station in preparation for their research project, they were surprised by unexpected rainfall—a brief yet notable shower.

Forget social distancing: House finches become more social when sick

Social distancing when sick has become second nature to many of us in the past few years, but some sick animals appear to take a different approach. A new study of house finches led by Marissa Langager, a Ph.D. student in the Department of Biological Sciences in the College of Science, has uncovered a surprising result. Unlike other social animals who passively or actively isolate themselves when...

Research highlights data gap in SARS-CoV-2 cases in animals

COVID-19 in animals? The question got lost in the shuffle during the ongoing global pandemic. Research on SARS-CoV-2 has primarily focused on its implications for humans, despite the virus most likely being a zoonosis, a disease transmitted from animals to humans.

Given the hostile conditions of extraterrestrial environments, unmanned rovers play a critical role in the exploration of planets and moons. NASA's Mars and lunar exploration rovers have significantly contributed to our understanding of these extraterrestrial bodies. Planetary surfaces often present challenging landscapes with slopes, craters, and dunes.

Children's spelling skills found to improve when teaching integrates movement
