J leads the twitter usage in Africa.
South African has the largest smartphone users in Africa.
A company start a research about a goe-tap twitter, but it cannot represent the total number.
The most popular topics are about xx products and xx service.
Companies, organizations and sports teams evolve in twitters use also.

Time 2 02:43.21
A research introduce a kind of warble to eat the insect in coffee planting farm, but this will lead a increase of trees and a reduce of the number of the coffee plants. The good news is the coffee yields will increase. So more trees =more coffees.

Time 3 03:16.11
Beer will help to reduce the production of PAHs in BBQ. Black beer reduce more PAHs than light beer does.

Time 4 02:42.30

time2 01:41To plant coffee trees close to forest might be a good idea. When planty birds are attracted to the coffee tree, oversize population will harm the harvest, but if there are forest around, birds will have plenty place to nest, and coffee tree will be benefit.
time301:48 BBQ comes with the harmful free radicals, but surprisingly beer could compromise the free radicals, esp black beer.
time4 02:02baby would change their habit from eating everything to be picky about new food. Research found that baby starts to form taste system during ages 2 to 6, when it resists dangerous food. But baby will accept what ever mom ate when she`s pregnant, because it felt familiar. So mom should eat whatever baby need to eat in the future.
time5 01:20 baby will accept certain flavor if it has been tried for 6-14 times, so parents should try more. There`s a tip about this method, try to give the baby all kinds of flavor, but in small portion.
time6 02:20 birds like to stay with frozen people, and such finding explains that birds are just like human, they like to perform collective movements.
obstacle 07:29
MI:how did the new stars form
the new stars just like earth distance and orbit, helping scientists to do research on its forming.
conventional opinion suggested that the stars are gas from magellanic clouds, however, new evidence proved that they are from the milky way galaxy.
They were formed by gravity from milky way galaxy, and gas was grabbed, while stars was sculpted into a significant grandeur. and as time passed by, stars have been used for many times, so it is a gaint now.

It talks about a good idea that mixing trees with coffee bushes could boost bird populations while improving crop yields.
[Time3]1’11’’
Adding some bear when barbecuing meat can reduce the risk of getting cancer due to eating barbecued food,and the black beer has the best effect.
[Time4]1’25’'
Kids between ages 2 and 6 are picky eaters and after that ages they turn to have taste preference.The taste preference starts in the womb and is due to the food which the pregnant women eat.

The main problem the coffee bean growers faced is a insect named borer. One solution is to introduce warbler, a insect eating bird, can keep insects in check. But sustaining a population of the birds is challenging. Biologists create a series of computer simulations of ecosystem in the coffee plantations and find that the replacement with 5% of random tress can increase the number of birds and reduce the infestation rate of borer thus increase corp yields.
Time3: 01'50''
The process of grilling creates molecules named PAHs which can damage DHA and thus increase the probability of developing colon cancer. A group of researchers found that by adding beer can avoid this heath killer since beers contained some chemicals called antioxidants will eradicate the free radicals in roasted meat.
