As they migrate(迁移), butterflies and moths(飞蛾) choose the winds they want to fly with, and they change their body positions if they start floating in the wrong direction. This new finding suggests that insects may employ some of the same methods that birds use for traveling long distances. Scientists have long thought that insects were simply at the mercy of the wind.

    Fascinating as their skills of flight are, migrating behavior has been difficult to study in insects because many long distant trips happen thousands of feet above ground. Only recently have scientists developed technologies that can detect such little creatures at such great heights.

    To their surprise, though, the insects weren't passive but active travelers on the winds. In autumn, for example, most light winds blew from the east, but the insects somehow sought out ones that carried them south and they positioned themselves to navigate(导航) directly to their wintering homes.

    Even in the spring, when most winds flowed northward, the insects didn't always go with the flow. If breezes weren't blowing in the exact direction they wanted to go, the insects changed their body positions to compensate(抵消). Many migrating birds do the same thing.

    The study also found butterflies and moths actively flew within the air streams that pushed them along. By adding flight speeds to wind speeds, the scientists calculated that butterflies and moths can travel as fast as 100 kilometers an hour. The findings may have real-world applications.

    With climate warming, migrating insects are growing in number. Knowing how and when these pests move could help when farmers decide when to spray their crops.

Fire Prevention Information

    The University of Adelaide employs a full-time staff of fire prevention professionals. They inspect all campus buildings and test and maintain all sprinkler(喷水灭火装置）systems, fire alarms, and fire extinguishers (灭火器). They also provide educational programs or fire safety in the residence hall. Whenever you move to a new area, you should locate the fire alarm pull stations and the two exits nearest your room.

Fire Alarms

    The floors of all campus buildings are equipped with manual(手动的）fire alarm systems which include fire alarm pull stations and pipes. Most are also equipped with automatic fire alarm systems consisting of heat detectors, smoke detectors and sprinklers. For your safety, never tamper with(胡乱摆弄）these systems. False fire alarms are illegal and may lead to imprisonment.

Fire Drills

    A fire drill will be conducted in your residence hall every semester. During a fire drill, please do the following:

    •Take your room key and ID, close and lock the door to your room.

    •Exit immediately from the nearest emergency exit do not use a lift.

    •Meet outside of your residence hall and wait for further instructions.

Fire Extinguishers

    Fire extinguishers are located on each floor and in each apartment. Use a fire extinguisher only if you have been trained to do so. Irresponsible use of a fire extinguisher can create a dangerous situation for other residents and could result in damage to personal property. Misuse of a fire extinguisher will result in fines.

Smoke Detector

    A smoke detector is on the ceiling in your room. Some buildings also have heat detectors on the ceilings. Do the following to ensure the safe operation of your smoke detector:

    •If your smoke detector is working properly, the red light should be on. If the red light is not blinking（闪动），contact residence hall staff immediately.

    •Do not cover or block your smoke detector in any way.

    •If a smoke detector sets off an alarm and there is no fire or smoke, inform your hall staff.

    Does the future of filmmaking lie in virtual reality (VR) films?

   An ambitious team led by Yale senior Celine Tien might hold the answer to that question.

    Tien produced,directed and acted in Pippa's Pan,which she says is “one of the world's first live-action VR films.”The film,which was completed in April,mixes live action with VR sections.Some of the characters were created via animation（动画）and other techniques that distinguish the film from 360° VR videos like the ones frequently seen on YouTube.

    “360° VR videos are stagnant,which means you don't move with them and see a 360° view of whatever they're filming.”Tien explained.“What we're doing is immersive（沉浸式的）VR.When you put on the goggles (a kind of special glasses) you can physic.ally walk around in the space,pick up objects and engage with the environment.It's a huge difference.”

    The immersive VR film experience is different for everyone who interacts with the medium,but that doesn't mean the film's ending will change for each viewer.

    The film stars two Chinese-speaking actors."It's a love story about a woman suffering from Alzheimer's disease who is trying to bring back memories of her husband,"Tien said.

    The film has already been recognized by the VR industry.After handing in a short demo to the AT&T Developer Summit Conference,Tien and her team were invited to Las Vegas in January,where they came in third place.

    If you're dying to see the film already,your choices area bit limited: Pippa's Pan can't be seen in movie theaters unless they happen to have VR goggles available.According to Tien,many theaters in China will soon have the ability,which makes sense considering China is the film's target market.

    Pippa's Pan will be released in three languages: Chinese,English and Korean.“It can get spread in different ways: at film festivals with VR set ups and through HTC or Oculus headset stores,”Tien says.“If you have VR goggles you can download it and experience it yourself.We will also cooperate with movie theaters that have VR set ups.”

    Alibaba started taking the lead in China by connecting big Chinese manufacturers（制造商）with big buyers across the world. Its business-to-business site, Alibaba.com allowed business to buy almost everything. Alibaba's advantage wasn't hard to judge: size. Alibaba is just big, even by Chinese standards. Its market attracts 231 million active buyers, 8 million sellers, 11.3 billion orders a year—and Alibaba is just the middleman. It encourages people to use its markets—not charging small sellers a percentage of the sale.

    If you want a quick look into the influence of Alibaba on daily Chinese life, take my experience. I moved to Beijing a year ago and quickly got tired of visiting small stores across the crowded, polluted city of 20 million people in search of new electronics, bathroom furnishings, and anything else my wife wanted. “You're looking for what exactly? Why not try it?” My Chinese teacher asked me one day. With that, my wonderful new relationship with Alibaba began.

    Alibaba's original business-to-business model now is second to consumer buying. Chinese retail（零售）buying makes up 80% of Alibaba's profit, and leading that group is Taobao, with 800 million items for sale and the most unbelievable selection of things you'll ever find. TMall.com is Alibaba's other big site, where you can find brand name goods from Nike and Unilever near the lowest prices.

    What I have a hard time explaining to friends and family back in the U.S.is how China has gone beyond traditional shopping—big-box retailers especially—in favor of online purchases on Taobao and a few other sites. In smaller towns than Beijing, where big retailers have not yet traveled, shopping online is shopping, and shopping is Taobao.

    I have a list of some of my recent purchases on Taobao for a sense of how wide the marketplace is. Almost everything arrived a day or two after ordering with free shipping. I'm not even a big buyer, because I need friends to help me search the Chinese-language site. When I was searching my purchase history on my Chinese teacher's iPad, which helps me buy goods, I looked through with great difficulty about 10 of her purchases for every one of mine.

    Having a busy schedule can result in disorder as well as the lack of not completing various tasks at hand.{#blank#}1{#/blank#}. Below are some tips of how to improve it.

    Establish a planning system

    There are several planning systems you can use.{#blank#}2{#/blank#}. With a planning system in place, when you have a task to do, you need to record the details of the task. Record what you need to do, the date it should be done and the time to complete the task.

    {#blank#}3{#/blank#}

    Having a busy day can result in disorganization and many tasks will not be done. When you check your planner before starting your day, you will know what should be done, at what time and for how long.

    Karen Bystedt was born in Israel, but lived in London and California as a child. In 1982, as a photography (摄影) student at New York University, she was photographing male models for a book when she came across an ad featuring Andy Warhol, a very famous artist. She thought it would be really great to put him in her book.

    So she called Andy Warhol at his studio in Union Square and asked if she could photograph him.

Two weeks later, Bystedt took a rented Hasselblad camera and lights to Warhol's famed "Factory" on 14th street. She ended up taking 36 pictures, and published two in her book, Not Just Another Pretty Face, published in 1983. Warhol came to its launch (发行) party—and that was the last time she saw him.

    A few years later, she packed the portraits in a box and moved to Los Angeles. But after she'd gotten settled, she couldn't find them. She couldn't remember whether she had given the photos away or just left them in some forgotten storage unit. Either way, she thought they were lost forever.

    In 2011, Bystedt became determined to find the missing films(底片). She spent two weeks going through two old garages, where she had put a bunch of belongings decades before. In a cardboard box, she found ten of the original films, covered in dust. She and a friend spent four months digitizing and cleaning the images up, pixel(像素) by pixel.

    Bystedt was not content to merely publish the unseen photos. She invited contemporary artists to paint over and around her Warhol pictures, breathing new life into her old work. So she began reaching out to artists, seeing if they would be interested in putting their own stamp on the pictures.

    The responses was overwhelming. Bystedt's new exhibit, "The Lost Warhols," opened on May 1, 2018 at 178 Sixth Avenue in Soho, New York, included 66 different interpretations of her portraits from 34 artists.
