1 . For people, many other animals, family matters. Consider how many jobs go to relatives. Or how an ant will cruelly attack intruder (入侵的) ants but rescue injured, closely related nest-mates. There are good evolutionary reasons to aid relatives, after all. Now, it seems, family feelings may stir in plants as well.

A Canadian biologist planted the seed of the idea more than a decade ago, but many plant biologists regarded it as heretical-plants lack the nervous systems that enable animals to recognize kin (家族), so how can they know their relatives? But with a series of recent findings, the belief that plants really do care for their most genetically close peers-in a quiet, planty way-is taking root. Some species control how far their roots spread, others change how many flowers they produce, and a few tilt (倾斜) or shift their leaves to minimize shading of neighboring plants, favoring related individuals.

“We need to recognize that plants not only sense whether it’s light or dark or if they’ve been touched, but also whom they are interacting with,” says Susan Dudley, a plant evolutionary ecologist, whose early plant kin recognition studies sparked the interest of many scientists.

Beyond broadening views of plant behavior, the new work may have a practical side. In September 2018, a team in China reported that rice planted with kin grows better, a finding that suggested family ties can be used to improve crop yields. “It seems anytime anyone looks for it, they find a kin effect,” says Andre Kessler, a chemical ecologist at Cornell University.

3 . Vancouver has had a crazy property (房地产) market since it hosted the winter Olympics in 2010. The downtown area is forested with new apartment blocks. Prices have risen by nearly 60% in the past three years. But until recently developers have largely avoided Chinatown. It is an underdeveloped area. Many Chinatown residents are old and poor.

Developers now have Chinatown in their sights. Two years ago one built a 17-storey apartment building on its edge. This alarmed many residents, who had formed a group to stop the high-rise advance, now called SaveChinatownYVR. Ms. Melody Ma is its leader. Recently it has been successful.

The main theatre of battle is a car park known as 105 Keefer, where Beedie Living plans to build a nine-storey brick-and-glass apartment block. The developer promises 111 luxury flats, with rooftop landscaping and shops below.

105 Keefer is in an area rich with cultural associations. Just to the south is a monument to Chinese-Canadian builders of the Canadian Pacific Railway and veterans of the Second Word War. Across the street is the Sun Yat-sen Classical Chinese Garden and the Chinese Cultural Centre Museum. “A lot of people were frightened” because of the building’s “closeness to sacred sites in the heart of Chinatown,” says Ms. Ma. Some residents also fear that it will push up rents.

Conservationists hope that the parking lot is where they can stop development, which they say has spoilt the charm of other Vancouver neighborhoods such as Mount Pleasant. The dispute (分歧) is part of a debate about the city’s identity, says Andy Yan, an urban planner. Vancouverites, he says, are asking themselves, “Who are we? And what are we building for?” The people who might want to buy the flats that do not yet exist are, of course, not being consulted.

5 . Vijay Gupta is known to classical music lovers across the United States. He serves as the first violinist for the Los Angeles Philharmonic. In that job, he often plays to large crowds, including many very rich people. When he is not performing, he organizes concerts for homeless people. “They have reminded me why I became a musician.” He said.

Last week, Gupta was recognized for being a founder and the artistic director of Street Symphony. The group has performed at homeless shelters, jails and halfway houses for about eight years. Gupta is among the 25 winners of the 2018 MacArthur Fellowship, commonly known as the “Genius Grant”. Each winner will receive $ 625,000 over five years to use as they wish. The money is coming from a private group, the John D. and Catherine T. MacArthur Foundation. It awards grants (补助金) to people whose work it considers exceptional and whose work “inspires hope in us all”. Gupta said he got the idea for Street Symphony while teaching Nathaniel Ayers, a trained musician whose mental illness led to his homelessness.

The 31-year-old winner said he did not know yet how he would spend the money. He has been a performer since the age of seven and the award will give him “space to breathe, plan and look ahead”.

Another winner is Rebecca Sandefur, an associate professor (副教授) of sociology and law in the University of Illinois. The Associated Press says her research actively supports new ways to involve poor communities in the U. S. justice system.

47-year-old Sandefur created the first national mapping of civil legal aid providers. It shows which states have the financial(金融的)resources to provide such aid and which don’t. She also found that the cost of legal services was only one of the things preventing poor people from getting lawyers. Among the others were fears of unfairness(不公平)in the legal system. Sandefur noted that a lot of attention had been paid to problems with the criminal justice system, but more attention must be paid to the civil side of the law, which also affected millions of people.

7 . The United States rose to global power on the strength of its technology, and the lifeblood that technology has long been electricity. By providing long-distance communication and energy, electricity created the modern world. Yet properly understood, the age of electricity is merely the second stage in the age of steam, which began a century earlier.

"It is curious that no one has put together a history of both the steam and electric revolutions." writes Maury Klein in his book The Power Makers, Steam, Electricity, and the Men Invented Modern America. Klein, a noted historian of technology, spins a narrative so lively that at times it reads like a novel.

The story begins in the last years of the 18th century in Scotland, where Watt perfected "the machine that changed the world". Klein writes, "America did not invent the steam engine, but once they grasped its passwords they put it to more uses than anyone else. "

Meanwhile, over the course of 19th century, electricity went from mere curiosity to a basic necessity. Morse invented a code for sending messages over an electromagnetic circuit. Bell then gave the telegraph a voice. Edison perfected an incandescent bulls that brought electric light into the American home.

Most importantly, Edison realized that success depended on mass electrification, which he showed in New York City. With help from Tesla, Westinghouse's firm developed a system using alternating current, which soon became the major forms of power delivery.

To frame his story, Klein creates the character of Ned, a fictional witness to the progress brought about by the steams and electric revolutions in America during one man's lifetime. It's a technique that helps turn a long narrative into an interesting one.
