In a paper published this week in the Royal Society's journal Interface, Waldrop explained that crabs use their bristly sense organs to find food in murky environments, track down mates, and avoid becoming someone else's lunch. To ensure that they were only relying on their sense of smell, the researchers had their subjects get down on all fours while blindfolded, ear-muffed and wearing thick knee pads and gloves. However, thanks to the work of conservationists, it seems like their numbers are increasing. That theory lacked any analysis of humans' actual olfactory abilities, McGann notes now. Slower upward strokes close the bristles and trap scents against chemosensory cells in the hairs to give the crab a whiff of what's nearby. The groundbreaking promise of cellular housekeeping. One of Earth's loneliest volcanoes holds an extraordinary secret. Other animals are especially well, lets say skilled at farting.
