For the last century, inflammatory bowel disease (IBD) has been a challenge for patients and the medical community in the western world. New research published today in The Lancet by Dr. Gilaad Kaplan shows that countries outside the western world may now be facing the same pattern of increasing IBD rates.
Researchers in Germany find that streetlights near waterways attract flying insects from the water and change the predator community living in the grass beneath the lights. The findings show that artificial night-time lighting could have implications for the surrounding ecosystem and biodiversity, which should be considered when designing new lighting concepts.
Environmental disturbances such as El Niño shake up the marine food web off Southern California, new research shows, countering conventional thinking that the hierarchy of who-eats-who in the ocean remains largely constant over time.
Biologist Douglas McCauley examines the benefits and drawbacks of virtual and augmented reality in teaching environmental science.
In 2013, an influenza virus began circulating among poultry in China. It caused several waves of human infection and as of late July 2017, nearly 1,600 people had tested positive for avian H7N9. Nearly 40 percent of those infected had died. In 2017, Yoshihiro Kawaoka of the University of Wisconsin-Madison received a sample of H7N9 virus isolated from a patient in China who had died of the flu. He and his research team subsequently began work to characterize and understand it.
New statistical simulations suggest that Northern Hemisphere flu pandemics are most likely to emerge in late spring or early summer at the tail end of the normal flu season, according to a new study published in PLOS Computational Biology by Spencer Fox of The University of Texas at Austin and his colleagues, Lauren Ancel Meyers (also at UT Austin) and Joel C. Miller at the Institute for Disease Modeling in Bellevue, Wash.
Interactions between species play a key role in shaping biodiversity. A team of researchers including members of UZH has now shown that the coevolution of species that are embedded in complex networks of interactions is not only influenced directly by their partners but also indirectly by other species. This slows down the ability of complex communities to adapt to environmental change. Rapid climate changes are therefore likely to increase species' risk of becoming extinct.
Populations of largemouth bass, bluegill, catfish and other sportfish are at the highest levels recorded in more than a century in the Illinois River, according to a new report. Their dramatic recovery, from populations close to zero near Chicago throughout much of the 20th century, began just after implementation of the Clean Water Act, the researchers say.
Duplications of large segments of noncoding DNA in the human genome may have contributed to the emergence of differences between humans and nonhuman primates, according to results presented at the American Society of Human Genetics (ASHG) 2017 Annual Meeting in Orlando, Fla. Identifying these duplications, which include regulatory sequences, and their effect on traits and behavior may help scientists explain genetic contributions to human disease.
For conservation to be effective, wildlife managers need to know how many individuals of a species are out there. When species are spread out over large areas and occur at low densities, this can be tricky. However, a new study applies an old technique called 'mark-recapture' in a novel way to count golden eagles, eliminating the need to actually capture and mark eagles with math that allows scientists to turn individual observations into population estimates.
