Microscopic plastic pollutants drifting through the air are lodging in the lungs of birds, a new University of Texas at Arlington study finds. Researchers worldwide are increasingly alarmed by how pervasive these harmful particles are in the air humans breathe and the food they eat. Shane DuBay, an assistant professor of biology at UTA and co-author of the study published in the Journal of Hazardous Materials, said birds were chosen for the study because they are found in almost every corner of the world and often share environments with humans.
The Hertz Foundation, a nonprofit dedicated to empowering the nation’s most promising innovators in science and technology, has named Chris Loose as chair of its Fellowship and Programs Council and ex-officio member of the board of directors.
A study co-authored by Filippo Radicchi at Indiana University proposed a theoretical framework specifically designed for understanding complex higher-order networks. The work could lead to breakthroughs in disciplines such as physics, neuroscience, computer science, climate science and finance.
Sleep is as important to humans as food and water, but it is often sacrificed to work, especially for farm workers. Dairy farming, in particular, can involve long hours and substantial physical activity, especially on farms that practice block calving—when cows in a herd all calve during a set period of time, usually over six to 12 weeks. Research into how these management practices affect the sleep quality of farm workers is extremely limited. A recent article in the Journal of Dairy Science documents how researchers in New Zealand are working to fill in the research gaps, illustrating that dairy farmers’ are generally getting less sleep and experiencing more stress during spring calving season—and highlighting ways farms can combat these trends.
