91.   Scientists have used tiny globules of fat to carry genes into damaged brain cells.

92.   Scientists use computer models to hunt for the genes.

93.   Scientists use high-performance liquid chromatography machines, probes, sensors, mass spectrometers and other instruments to separate and analyze chemicals.

94.   Scientists usually use the notion of God metaphorically.

95.   SETI scientists never use the network of dish antennas there because they are not suited for their aims.

96.   Seed said he plans to use the same technology that scientists used to clone a sheep.

97.   Scientists already use unpiloted high-altitude balloons extensively to conduct some kinds of environmental monitoring and astronomical studies that require a perch high above most of the atmosphere.

98.   Scientists are using lasers to nudge clouds of atoms into tiny traps where the properties of the particles can be studied.

99.   Scientists are using this knowledge to develop windows that reflect heat back into a house in winter, and reduce heat gain in the house during summer.

100.   Scientists then use these models to forecast climate conditions around the globe.
