Researchers recently have found some remains of an ancient body, maybe belonging to Rechard III,a king of U.K. Surprisingly, they discovered some roundworms' eggs, which are highly suspected to cause the death of the king, because there are few eggs around the body, suggesting that these eggs came from the body itself. Even though some people may get some worms in their guts by eating some meat, cooking prevents infection. Maybe Rechard III got these worms from water or raw food.

Conducting a series of experiments, scientists find that a kind of speices, usually thought to be parasites, may be helpful for the hosts to defend against invaders. When S ants live without G, which is the parasites, M ants can occupy S ants' nest and hurt S ants. However, When S ants live with G, M ants won't come to hurt S ants and instead will combat with other M ants. It's really amazing.

Fathers who care more about their children may have smaller testicles than other fathers, a result suggested by some recent studies. Scientists make comparison betwwen different primates and find that those with large testicles pay less time taking care of their children. Also, scientists do a research about many fathers and their children, observing father's brains.

On one hand, when some fathers with smaller testes are showed their children's pictures, their VTP is active. What's more, these fathers are thought highly of caring their children by mothers. On the other hand, other fathers who are thought to care little about their children by mothers shows low level of VTP, while looking at their children's pictures. Scientists relate VTP to the care of children. However, some scientists think other factors except the size of the testis can also play a role in child care. For example, the social pressure or the care that these fathers got from their fathers in childhood. So further researches may produce more convincing results.

Showing a large amount of carbon around the center of the star, a faraway denying star is observed by a radio telescope, helping us to analyze the construction of the star, such as the amount of carbon, oxygen, and hydrogen.

The author cites the debate about plate tectonics to show that different views can be valid until a consensus occurs. Even though people can deny some explanations, they should admit the right one when they are showed valuable evidence.
