Even though people found the water bridge 120 years ago, the reason why the bridge couldn't collapse hasn't been discovered. Now scientists surprisingly find that maybe two reasons together can explain the situation, the de tension and surface tension. The discovery may help us to design better screen of e-book.

Lucy, the ancient skeleton found by people, gets a new makeover, showing that she might spend a lot of time on ground because of her big feet, even though she also climbed in the tree. Researchers find some new ribs and other fossils of Lucy, so they make a new image of Lucy. The model is exhibited in a museum.

T is the third and the strongest typhoons this year, causing 30 people died in HongKong and thousand of mainland residents to evacuate. Actually, typhoons, hurricanes, and cyclones are the same weather phenomenon, but we judge them in terms of the location where they are formed. Besides, we classify different levels of hurricanes, typhoons, and cyclones accoring to their speeds.

The seasons of hurricanes, typhoons, and cyclones may be distinctive. No matter what kind of hurricanes, they have their own hurricane eyes. Some hurricanes may be so strong that they can destory everything that they come across. On the other hand, with the evidence that since 1970 there have been more and stronger hurricanes than before, people suspect that the global warming which is related to human activities may result in the increasing hurricanes around the world. However, we cannot make the judge until we find more convincing evidence.

C, a new battery, has recently been devised, with such advantages that it can be made cheaply and safely. Then the author talks about how the battery can be produced. For example, there are two electrodes and a thin membrane to separate the electrodes. In addition, the material is metal, such as zinc, not expensive. The advantage of the battery is that it involves a near neutral solution to react, much safer than the conventional batteries. In the end, the author points out that the researchers are trying to attract more investment to improve the production.
