Main idea: Artificial sweeteners might influence gust becterias associated with obesity.
Atitude: contains multitude
structure: microbiome -immune system
study mice intestinal beat but robust
mice fed sweeteners have no gust.
difference between mice and human.
find weight loss in people who consumes sweeteners
tend to eat less; many things contain sweeteners--无法控制变量
individuals differ-affect only some

thank you. Very useful topic.

The author simply introduces the report about the future plan of US nuclear fusion research. The report says that in order to free up more money, the US should focus on development and thus close other two operations. However, some scientists show their unsatisfaction about this report, and they may try to solve the problem of funding by themselves.

In, A team of astronomers using the BICEP2 radio at the South Pole announced that they detected a twist, which was probably caused by gravitational waves. However, another team, Planck team, asserted that the tiny twist was due to ordinary dust rather than gravitational waves. In order to prove that, the Plank team released a map showing the twist owing to dust over the entire sky. According to this map, the dust level was much higher in the region around the South Pole than was estimated by BICEP2 team, making it possible that the twist was caused not by gravitational waves but by dust. However, some scientists mentioned that such twist might be caused by both gravitational waves and dust.

Scientists have created Diet Coke, which contains no sugar at all but can be tasted as sweet as Coca-Cola can. That is because of artifical sweetners, than these sweetners may be able to help people loss weight. However, some scientists argues that such antifical sweetners can even cause people to gain weight, even though they don't contain any sugar at all. By making an experiment on some groups of mice, these scientists prove that sweetners will have a bad effect on the microbes that live in mice's guts, indicating that such sweetners will also influence the microbes that live in people's guts. But the epidemiological research shows that people who drink sweetened with aspartame and the like actually reduce their weight. Because of the discrepancy, it still needs some experiments to make a conclusion.

after the chicxulub meteorite, more than 1/2 plant species perished along with the dinosaurs,and the composition of thrived species changed markedly, which were fast growing and more adaptable seasonal plants.

the latest interstella dust map could guide astronomurs to detect gravitational waves, which would have constituted proof for universe inflation.

[Time 5]00:01:56.40
Plank team released the map.which show that dust polarization is signficantly higher in the region around the south pole than was estimated by the BICEP2 team.

[Time 6]00:01:43.38
the amount of dust polarization affects the detection of gravitational waves from the early universe.

[Paraphrase 7]00:09:20.42
artifical sweetener are not directly bad for people. but they may be bad for microbes that live in people's gut.and in turn may be bad for their human host.
