...matopoietic, or blood-forming, stem cells prefer a solitary life. "We took time-lapse movies of sections from mouse leg bone as seen under a fluorescent microscope," says Douglas Engel, Ph.D., chair and professor of cell and developmental biology at the U-M Medical School, who is the corresponding author for...ASU researchers find link between social behavior, maternal traits in bees

...miles or more, often in just one night. "The first solitary coyote we tracked covered five adjacent cities in a single night," Gehrt said. Urban coyotes survive far longer than their rural cousins. A coyote living in urban Chicago has a 60-percent chance of surviving for one year, while a rural coyote has a 3......-accepted. Some species (of mole-rat) are strictly solitary while others, such as the naked mole-rat, are highly social." DNA markers, like the satellites, are important because they can reveal how traits pass from one mother to her multitude of babies conceived by various interrelated fathers. That may help ...America's public forests landlocked by sea of development
... says Radeloff. If trends continue, he adds, these solitary moments and discoveries will be more and more difficult to experience. Housing in and around forests not only affects biodiversity, it impacts hydrology cycles and accelerates the spread of invasive species. Wildfires and animal-human conflicts are ...Genome of a social amoeba sequenced for the first time
...vel therapeutic approaches. Starvation prompts the solitary cells to aggregate and develop as a multicellular organism consisting of up to 100,000 cells, where individual members of the community sacrifice themselves to ensure the survival of others. In terms of its developmental lineage, the social amoeba da...Symbiotic bacteria protect hunting wasps from fungal infestation
...microbes. In the new work, researchers show that a solitary ground-nesting wasp, the European beewolf, harbors Streptomyces bacteria in unique structures within its antennae and that females utilize these bacterial symbionts to protect the wasp larvae against pathogenic fungi.
