Rockets and space shuttles can now fly into outer space. Weather and Weather-related Disasters Through meteorological science and technological advancements, weather forecasts are predicted with varying degrees of accuracy.
Predictions help keep people safe in areas where major storms are going to hit. These predictions give enough warning now for people to be able to evacuate for the storms arrive.
This includes hurricanes, tornadoes and earthquakes. In less extreme ways, weather forecasts help people plan for travels or daily treks. This might include hailstorms, thunderstorms, floods, snow or excessive heat or cold. Science in Medicine Science makes life safer in medicine. Antibiotics heal bacterial infections.
Vaccinations protect people from diseases that were once considered fatal, such as tuberculosis and polio.
Current vaccinations prevent shingles and influenza. Blood tests can determine cholesterol and sugar levels as well as vitamin deficiencies. Medical equipment offer views of the inside of human and animal bodies to detect abnormalities.
This is done through the use of X-rays, magnetic resonance imaging and computed tomography, among others. Medicine is one of the quickest changing and evolving forms of science.
Plants and Food Science is responsible for plants that grow in greenhouses. It keeps farmers working more efficiently and irrigation systems watering large fields of crops.
A sprinkler waters a small yard to keep the grass green. Foods can be bought out of season due to botanical advancements and transportation options. Hybrids and more varieties of foods are offered.
Vitamins, minerals and caloric values in foods can be calculated to maintain health benefits.
Pesticides can ward off contaminants. Fertilizers improve growth in plants and blossoms in flowers.
