Day 43 ------speaker The conversation is about how parents manage kids’ media consumption. The doctor suggested that touch screen apps provide opportunities for kids to interact with environment, which is good to their learning process and brain development. While for TV consumption, overstimulation and fast pace are common for kids. Experiment conducted within mice showed that hyper-stimulated mice who watched fast pace TV programs regularly demonstrated deficits in cognition, and they are more risk-taking and have few friends. For new devices like ipads, researches have not catch up with new techs for their slow pace. The doctor indicated that ipad might be fine and beneficial to kids as it draws attention of kids and help them to interact by using touch screen. ----speed 1. 0’51 Recent new studies show that northern Alabama and South America used to be neighbors, and rocks beneath North America were formed before tectonic activity separated the two areas. 2. 1’27 Researchers are investigating new methods to treat binge eating disorder. They want to identify patterns that trigger the disorder and develop strategies to change eating habits. Trails will be studied and comparison of traditional treatments will be performed. 3. 2’00 As pests will develop resistance to toxins after a period of time, switch crop plants is a method to resist pests. 4. 1’15 New tech can develop two toxins in one crop, however the effect is limited as it is only the time issue for pests to develop resistance to the toxins. New tech combines with old crop rotation method is the best way to kill pests. 5. 0’51 Some string quartet players follow one leader while some payers equally rotate the role of leader. Further researchers are needed to investigate patterns hold up. -----obstacle 5’32 Observation of gravitational wave indicates that the universe expanded exponentially in the very first moment, which demonstrates how the universe was born. Gravitational wave was observed from their effects on cosmic microwave background in Antarctic. And polarization pattern was observed twice stronger than what we expected, showing more strongly gravity we assumed before. All these observation help researchers to make sure that the universe grow exponentially and create gravitational wave in the very fist second of the big bang, and the universe reached a size far larger than human being can observe.
