Holding Breath
TIME breaks cockroaches and other bug periodically stop breathing. Scientists still can not understand this. A hypothesis says it is caused by the closure of a small valve on the breathing of their exoskeleton called the vent (spiracle). Recently, the researchers tested the truth of this theory through the placement of cockroaches in the room with different humidity levels for five weeks. After adjusting to the climate, fleas in the dry room to open their vents about 40 percent less than in the humid room. So the researchers report, The Journal of Experimental Biology edition of September 1.
