1'42''[217]: scientists could track the dash plume after the expulsion of a space rocket.
1'31''[271]: Scientists find a coating ingredient formed in water and constitute by iron and other compounds. This coating ingredient is safe and easy to make. It can be used in various area, such as delivering drug, cosmetic, and food. It can be kept intact in a long period, and it also can be easily disseminated through simple steps.
2'27''[371]: A report shows that US behavior researchers, compared with non-US behavior researchers are more likely to exaggerate their research result. It is called US-effect. The effect is not shown in non-behavior research area. Scientists think that it is because behavior experiment is more flexible for researchers to report extreme result, because behavior research involves more behavior variables. This methodology is flexible and has various behavior factors .
2'20''[373]: This experiment is based on a larger volume than previous research. However, it merely shows that there is a correlation between US behavior research and extreme report. An explanation of this result is that behavior research is more various than non-behavior research. But people are curious about why the final results are always in favor of authors' hypotheses. Someone guess that it might be caused by the phenomenon that scholars intend to publish paper in high-level journals in order to earn research funding.
2'28''[308]: There is a new technique to distinguish Kopi Luwak coffee from fakes. Kopi Luwak is an expensive type of coffee. A research reveals that Kopi Luwak coffee, compared with other coffees or their mixture, contains high concentration of malic acid and citric acid, and higher ratio of A to B. Although experts and specific device can tell authentic Kopi Luwak coffee, it is the first time that we can analyze the chemicals of authentic Kopi Luwak .
obstacle 8'40''[1209]:
An iphone might cost much energy than does a refrigerator .
6 devices in your home might burn much power than you expected.
(introduce how does each device cost your energy and how to fix this problem)
set-top box: connect the cable to your entertainment system, always run on full power,
furnace fan: under your basement, circulate the air,
Microwave oven: cost power when it is not be used
cooling pump: cost much power than warming systems
charger: developed in old fashioned technology, cost power
game consoles: do not forget to turn it off
