9．From self-driving cars to deep sea explorers，more and more of humans'tasks are being taken over by robots．But technology doesn't stop there．In mid-August，reported the BBC，scientists from Cambridge University developed a robotic system that meant a robot could"build other robots，each one better than the previous（以前的） generation"．
The BBC noted that"those concerned about machines taking over the world shouldn't worry"．
However，over 1，000 scientists and numerous artificial intelligence （AI，人工智能） researchers-including UK astrophysicist Stephen Hawking and Apple cofounder Steve Wozniak of the US-brought the danger of fully autonomous weapons（自主武器），known as"killer robots"，to our attention earlier this summer．
"If any major military（军事的） power pushes ahead with AI weapon development，a global arms race is inevitable（不可避免的），"warned an open letter released at the International Joint Conference on Artificial Intelligence held in Buenos Aires，Argentina．
Unlike drones（无人机），which need a human hand，this kind of robot would have some decision-making abilities and the ability to act by itself．While what the BBC called these"solders that never sleep"could help reduce battlefield deaths，they might also make countries more likely to go into battle，which would lead to more deaths overall，noted the scientists．The risks，they said，could be far greater than those posed by nuclear weapons．
Scientists called for a"ban on offensive（攻击性的） autonomous weapons beyond meaningful human control"，reported The Huffington Post．
In fact，in an interview with the BBC in 2014，Hawking warned that the"development of full artificial intelligence could spell the end of the human race"．
And according to the BBC，many leading thinkers have been thinking about the AI-powered killing machine of the not-too-distant future．"Killer robots could be here within years，not decades，"as Stuart Russell，professor of computer science at UC Berkeley，US，put it．
Authorities are gradually waking up to the risk of robot wars．Last May，for the first time，the United Nations brought governments together to begin talks on so-called killer robots in a hope of stopping such weapons while there is still time．
Meanwhile，there are scientists who are less worried．They believe all technologies have potential（潜力） for being used for good and evil ends，and argue that the ban called for by the open letter could close the door to developing AI technology that could save lives．"Technology can clearly do better than human beings in many cases，"Ronald Arkin，dean at the Georgia Institute of Technology in Atlanta，US，told The Christian Science Monitor．"If we are willing to turn over some of our decision making to these machines，we may actually get better outcomes．"

8．Restaurants in Miami BeachSteve's Pizza
So many pizza chains compete for the attention of tourists in South Beach，but ask a Miami Beach local where to get the best pizza and they'll tell you about Steve's．This is New York style pizza，handmade with care and good ingredients（成分）．New branches of Steve's Pizza are opening elsewhere in Miami，all in non-tourist areas．
Opening hours：11a．m．-10a．m．
Cattleman's Steakhouse
This place is 20 miles east of the city，but local folks would probably drive 200 miles to eat here．The food is good，and the scenery is even better．Come early and wander around the grounds of Indian Cliffs Ranch，where you'll see everything from rabbits to buffalo （水牛），then catch the sunset either before or after your meal．
Opening hours：5p．m．-10p．m．
Absolute Baking & Café
The screen door is always swinging open at this town hot spot with giant breakfasts．Try the green chili on eggs-it's made from scratch，as are the organic（有机的） breads．Lunch includes salads，big sandwiches and local grass-fed beef burgers．Don't miss a square of soft，fresh carrot cake．
Opening hours：7a．m．-2p．m．
Walt's Wharf
Everybody's favorite for fresh fish （some drive in from LA）．Walt's packs them in on weekends．You can't make reservations for dinner （though they're accepted for lunch），but it's worth the wait for the tree fire-grilled seafood and steaks in the many-windowed ground floor or upstairs in captain's chairs．
Opening hours：11a．m．-10：30p．m．

4．Thanks largely to the Kepler space telescope，astronomers have discovered more than 2，000 planets in the universe．Kepler's final goal is to find worlds similar to Earth-places where there's a chance that alien life might exist．
But the search for life will still not be easy．It will be important to choose the best possible targets．That's the reasoning behind two new rating systems （评估体系）proposed by Washington State University environmental scientist Dirk Schulze-Makuch，along with nine other colleagues．
The first rating system is called the Earth Similarity Index，or ESI．That's just what it sounds like：it's a measure of how closely an alien world matches Earth in terms of size and temperature．The temperature is important because liquid water is an important part for life．
The size of the planet seems important too．If a planet is too small，like Mars，it might not have enough gravity （引力） to hold on to its atmosphere．If the planet is too big，gravity might have pulled in too much atmosphere，which would create too much pressure at the surface．A world four or five times as large as Earth might be able to support life．But anything bigger than that could cause problems．
This second system is called the Planetary Habitability Index，or PHI．It includes planets that have a solid surface of some kind，protected by an atmosphere of some kind．Other things necessary under the PHI system are some sort of energy source（sunlight）；some sort of chemical environment that allows the formation of complex molecules（分子）； and the presence of liquid-but not necessarily water．
The search will get easier as technology improves．Still，these new ways of looking for alien life give us our best chance of learning if somewhere out we have galactic （银河的）relatives．
