1 . That dinosaurs ate the mammals (哺乳动物) that ran beneath their feet is not in doubt. Now an extraordinary fossil newly described in Scientific Reports, unearthed by a team led by Gang Han at Hainan Vocational University of Science and Technology in China, shows that sometimes the tables were turned.
The fossil -dated to about 125 million years ago, during the Cretaceous period-was formed when a flow of boiling volcanic mud swallowed two animals seemingly locked in a life-and-death fight. The one on top is a mammal. This animal is a herbivorous species closely related to the Triceratops (三角恐龙). Animal interactions such as this are exceptionally cam e in the fossil record.
One possibility is that the mammal was eating something already dead, other than hunting live prey. These days it is uncommon for small mammals to attack much larger animals. But it is not unheard of. And Dr. Han and his colleagues point out that those mammals which eat dead bodies typically leave tooth marks all over the bones of the animals. The dinosaur’s remains show no such marks. There is also a chance the fossil could be a fake. More and more convincing fake s have emerged, as this one did -though Dr. Han and his colleagues argue that the complexly connected nature of the skeletons (骨骼) makes that unlikely, too.
Assuming it is genuine, the discovery serves as a reminder that not all dinosaurs were enormous during the Cretaceous and not all mammals were tiny. From nose to tail, the dinosaur is just 1.2 meters long. The mammal is a bit under half a meter in length. Despite being half the size, the mammal has one paw firmly wrapped around one of its prey’s limbs, and another pulling on its jaw. It is biting down on the dinosaur’s chest, and has ripped off two of its ribs. Before they were interrupted, it seems that the mammal was winning.

4 . Women were less likely than men to support the Vietnam war, the Gulf war, or the invasions of Afghanistan and Iraq. They commit far fewer murders. They are less likely to favor strikes. For some scholars, these are grounds for thinking that a world run by women would be more peaceful.
But European history suggests otherwise, according to political scientists Oeindrila Dube and S. P. Harish. They studied how often European rulers went to war between 1480 and 1913, and found that states ruled by queens were 27% more likely to get involved in wars than those ruled by kings.
This was not all the queens’ fault: men, seeing them as soft targets, tended to attack them. Frederick the Great of Prussia once declared: ”No woman should ever be allowed to govern anything.“ Shortly after becoming king, he attacked the newly crowned Archduchess of Austria, Maria Theresa, and seized Silesia province. Despite years of war, she never recovered it.
But perceived weakness is not the whole story. Queens, the researchers found, were more likely to gain new territory. Catherine the Great expanded her empire by some 200,000 square miles. And married queens were more aggressive than single queens or kings, whether single or married.
The authors suggest several reasons for this. First, married queens may have been able to form more military alliances(联盟),making them confident enough to pick fights. Their husbands had often served in the army before they married, and were well placed to strengthen military ties between their homelands and their wives’ states.
Second, unlike most kings, queens often gave their husbands a lot of power,putting them in charge of foreign policy or the economy. During the 1740s, Maria Theresa’s husband, Francis I, reformed the Austrian economy and raised money for the armed forces while his wife ruled much of central Europe. Prince Albert was Queen Victoria’s most trusted adviser, shaping her foreign policy until his death in1861. This division of labor, the authors suggest, freed up time for queens to pursue more aggressive policies.
The modern era, too, has witnessed female leaders in wars: Golda Meir and the Yom Kippur war, or Margaret Thatcher and the Falklands. The number of countries led by women has more than doubled since 2000, but there is plenty of room for improvement: the current level of 15 represents less than 10 % of the total. A world in which more women took power might be more equal. Whether it would be more peaceful is a different question.

8 . Walled Cities Of The World
There are numerous historical walled cities across the world, whose walls date back several centuries. These walls were fortification (碉堡), a necessity throughout medieval eras for defense. They have been preserved as historical monuments and popular tourist attractions in the modern time.
York, England
The city of York is a medieval city situated in the north of England. Historically, the city was ruled by the Romans, Angles, and the Vikings before being incorporated as part of the Kingdom of England in 954. Located in the city are walls built in 71 AD which have been restored and extended with time.
Xi’an, China
The city of Xian is one of the oldest cities in China. It prospered economically as the eastern last station of the Silk Road. The existing walls were originally built in 770 BC and reconstructed in the 14th century under the Ming Dynasty. The walls are well preserved and are a major tourist attraction in the city.
Quebec City, Canada
Quebec City was a colonial (殖民地的) town which was fortified by the settling Europeans. The walls began to be built in 1608 under both British and French regimes (政权). A fort was constructed by the British as an additional defensive measure and remains undamaged to date. The city’s fortifications were listed as a UNESCO World Heritage Site in 1985.
Mexico City, Mexico
Historically, the City of Mexico gained importance as the Aztec Capital. The Spanish then drove out the Aztecs and rebuilt it as the Spanish Capital. The walls protecting the city were built in 1521. Mexico City is also home to numerous colonial-era buildings which together with the walls are major tourist attractions in the city.
