Many of North America's migratory songbirds, which undertake awe-inspiring journeys twice a year, are declining at alarming rates. For conservation efforts to succeed, wildlife managers need to know where they go and what challenges they face during their annual migration to Latin America and back. For a new study published by The Condor: Ornithological Applications, researchers in six states assembled an unprecedented effort to track where Prothonotary Warblers that breed across the eastern U.S. go in winter—their "migratory connectivity"—and found that nearly the entire species depends on a relatively small area in Colombia threatened by deforestation and sociopolitical changes.

Scientists studying how large-scale environmental disruptions affected ancient societies
John Day, Distinguished Professor Emeritus in LSU's College of the Coast & Environment, has collaborated on a new analysis of societal development with Joel Gunn of the University of North Carolina at Greensboro, William Folan of the Universidad Autonoma de Campeche in Mexico, and Matthew Moerschbaecher of the Louisiana Oil Spill Coordinators Office. Gunn and Folan are Mayan archaeologists and Moerschbaecher is a graduate of LSU's oceanography program. They report that over the past 10,000 years humanity has experienced a number of foundational transitions, or "bottlenecks." During these periods of transition, the advance or decline of societies was related to energy availability in the form of a benign climate and other factors.

Microfluidics device captures circulating cancer cell clusters
Cancer touches nearly everyone in one way or another, and regrettably, it will claim another 600,000 lives in the U.S. in 2019, according to the American Cancer Society. Researchers from San Diego State University, TumorGen MDx Inc., and Sanford Burnham Prebys Medical Discovery Institute set out to explore a seemingly basic question: What is it about cancer that kills?

Food neophobia may increase the risk of lifestyle diseases
Food neophobia, or fear of new foods, may lead to poorer dietary quality, increase the risk factors associated with chronic diseases, and thus increase the risk of developing lifestyle diseases, including cardiovascular diseases and type 2 diabetes.

To improve drones, researchers study flying insects
The unmanned aircraft known as drones, used by hobbyists, researchers and industry to take aerial images and perform other tasks, are growing ever more popular—and smaller. But that miniaturization, which has produced drones that fit in a person's palm, has started to bump into the laws of physics.

Collegiate affirmative action bans tied to rise in smoking among minority high schoolers
College affirmative action bans may adversely affect the health of underrepresented minority high school students, according to the results of a new study from researchers at Penn Medicine. Between 1996 and 2013, nine U.S. states banned consideration of race and ethnicity in college admissions. A new study in PLOS Medicine shows that the action bans had unanticipated effects, specifically resulting in increased rates of smoking among minority high school students. The researchers also found evidence to suggest these effects could persist, as these students were also more likely to smoke into young adulthood compared to those who lived in states where an affirmative action ban was not enacted.

Applying active inference body perception to a humanoid robot
A key challenge for robotics researchers is developing systems that can interact with humans and their surrounding environment in situations that involve varying degrees of uncertainty. In fact, while humans can continuously learn from their experiences and perceive their body as a whole as they interact with the world, robots do not yet have these capabilities.
