Fossilized corals from tropical Tahiti show that the behavior of ice sheets is much more volatile and dynamic than previously thought, scientists have found.
Biologists researching the behavior of field crickets have found that female crickets remember attractive males based on the latter’s song, and use this information when choosing mates. The researchers found that female crickets compare information about the attractiveness of available males around them with other incoming signals when selecting attractive males for mating. The finding [...]

Researchers can now describe one of the missing triggers that controls calcium inside cells, a process important for muscle contraction, nerve-cell transmission, insulin release and other essential functions. The researchers believe the findings will enhance the understanding of how calcium signals are regulated in cells and shed light on new ways to treat many diseases, [...]

A longitudinal study of American children finds that children who witnessed domestic violence against their mothers were almost four times more likely than other children to develop emotional or behavioral problems. The study also finds that more than half of the children exposed to violence adapted well, at least in part because of their easy-going [...]

Living beings and inanimate phenomena may have more in common than previously thought. What two researchers believe connects the two worlds is a theory that flow systems — from animal locomotion to the formation of river deltas — evolve in time to balance and minimize imperfections.
