Smithsonian's National Zoo researchers use electronic eggs to help save threatened species
...gs surface as well as in the eggs interior. Motion detectors record how frequently the mother turns the egg during incubation. The data are recorded 24 hours a day and downloaded to a computer every 48 hours. National Zoo staff use the information to mimic natural incubation in a controlled setting in the lab....Nanotechnology helps scientists make bendy sensors for hydrogen vehicles
..., could not be easily detected by individual rigid detectors because the locations of pinholes are not predetermined, said Sun. However, laminating a dense array of flexible sensors on the surfaces of the pipe can detect any hydrogen leakage prior to diffusion to alert control units to take action. Flexible ...
