3 . One Saturday in June, I got off the train from Vienna at Altenberg station, in the midst of a gathering of bathers, such as often flock to our village at fine weekends.
I had gone only a few steps along the street and the crowd had not yet scattered when, high above me in the air, I saw a bird whose species I could not at first determine. It flew with slow, measured wing-beats, varied at set intervals by longer periods of gliding. It seemed too heavy to be a hawk; for a stork (鹳), it was not big enough and, even at that height, neck and feet should have been visible. Then the bird made a sudden turn so that the setting sun shone for a second full on the underside of the great wings which lit up like stars in the blue of the skies. The bird was white. By Heaven, it was my cockatoo (凤头鹦鹉)! The steady movements of his wings clearly indicated that he was setting out on a long-distance flight.
“What should I do? Should I call to the bird?” Well, have you ever heard the flight-call of the greater cockatoo? No? But you have probably heard pig-killing in the traditional method. Imagine the loudest long cry a pig could make, picked up by a microphone and amplified many times over by a powerful speaker. A man can imitate it quite successfully, though somewhat weak, by shouting at the top of his voice “O-ah”. I had already proved that the cockatoo understood this imitation and promptly “came to heel”. But would it work at such a height? A bird always has great difficulty in making the decision to fly downwards at a steep angle. To yell, or not to yell, that was the question. If I yelled and the bird came down, all would be well, but what if it sailed calmly on through the clouds? How would I then explain my song to the crowd of people?
Finally, I did yell. The people around me stood still, rooted to the spot. The bird hesitated for a moment on outstretched wings, and then, folding them, it descended in one dive and landed upon my outstretched arm. Once again I was master of the situation.

5 . A songbird jumps around in the woods near Washington, D. C. On its back it carries a very small, lightweight electronic device called a tag (标签). Ecologist Emily Williams watches from behind a bush. On this clear spring day, she says, “Now I’m watching to see whether he’s found a mate.” The bird has moved to a nearby tree where there is another robin. When the bird leaves, this new device it carries will send data about its position to a special satellite, then back to Williams’ computer.
The Georgetown University researchers have been attaching tracking (跟踪) tags on birds and animals for many years. But, the International Space Station and the involved satellite now provide new ways to receive the information sent by the tags. The new system permits scientists to watch songbird movements from a faraway place in much greater detail than before.
“We’re in a sort of golden age for bird research,” said Adriaan Dokter, an ecologist at Cornell University, adding that the technology is improving as the tags are made smaller and smaller. “We can track a robin by satellite with smaller and smaller chips. The device that the robin wears can report its immediate place on Earth, within about 10 meters. Ten years ago, that was unthinkable,” said the scientist, who is not involved in Williams’ study.
A second new device, for only the heaviest robins, provides more information about the bird’s movements; future versions may also measure the humidity and barometric pressure of the space the bird occupies. The devices are known as ICARUS tags.
Martin Wikelski is director of the Max Planck Institute of Animal Behavior. His scientific team is working to improve the ICARUS technology. He hopes that more and better devices could help develop what he called “an Internet of animals”—a collection of sensors around the world giving us a better picture of the movement of life on the planet.

8 . The Thermo Fisher Scientific Junior Innovators Challenge is a science competition for U. S. middle-school students. It's run by Society for Science, which also publishes Science News Explores. The 30 finalists in this year's competition traveled to Washington, D. C. and also showed off their research projects.
Sharanya Chudgar, 14 years old, is one of the finalists in the competition and built a trash-collecting robot. The wheeled machine of the robot uses sensors to spot litter and a pan to pick it up. The robot's metal-detecting sensor helps it sort garbage from recyclables. And a light sensor can let the robot's solar panel angle itself toward the sun, collecting as much energy as possible.
Sharanya got the idea to build her trash collector by participating in litter cleanups. "When I signed up to volunteer at our local trash cleanup, I saw how much litter poliution there was and I knew that I had to fix this problem," Sharanya says. "People do have very limited time and resources, right? But robots don't. So it was then that my project idea formed in my head."
"Building the robot is my favorite part of this project," Sharanya says. "Ever since first grade, I've loved building Legos and building my robot felt just like building a Lego. But this project was a completely new experience since I hadn't ever had any experience in robotics before. Throughout the project, I had to use tons of power tools and I even had to cut pieces of metal to certain lengths. Whenever I needed to use a power tool, I had to turn to my dad who was always there to help out if necessary."
"It might seem difficult at times, but sticking to this and changing just one variable at a time gets you the best results," Sharanya says. This middle school scientist is solving global problems of litter pollution. For some, a science project might be an assignment or a fun hobby. But for Sharanya, doing research can also be a chance to help others and make the world a better place.

9 . Until recently, gravitational waves could have been the stuff of Einstein’s imagination. Before they were detected, these waves in space time existed only in the physicist’s general theory of relativity, as far as scientists knew. Now, researchers are on the hunt for more ways to detect the waves. “The study of gravitational waves is booming,” says astrophysicist Karan Jani of Vanderbilt University in Nashville. “This is just remarkable. No field I can think of in fundamental physics has seen progress this fast.”
Just as light comes in a variety of wavelengths, so do gravitational waves. Different wave lengths point to different types of origins of the universe and require different kinds of detectors. Gravitational waves with wavelengths of a few thousand kilometers—like those detected by the United States, Italy and Japan—come mostly from pairs of black holes 10 or so times the mass of the sun, or from collisions of dense cosmic blocks called neutron stars (中子星). These detectors could also spot waves from certain types of exploding stars and rapidly moving neutron stars.
In contrast, huge waves that span light-years are thought to be created by orbiting pairs of bigger black holes with masses billions of times that of the sun. In June, scientists reported the first strong evidence of these types of waves by turning the entire galaxy (星系) into a detector, watching how the waves make slight changes to the timing of regular blinks from neutron stars throughout the Milky Way.
Physicists now hope to dive into a vast, cosmic ocean of gravitational waves of all sorts of sizes. These waves could reveal new details about the secret lives of exotic objects such as black holes and unknown parts of the universe.
Physicist Jason Hogan of Stanford University thinks there are still a lot of gaps in the coverage of wavelengths. “But it makes sense to cover all the bases. Who knows what else we may find?” he says. The search for capturing the full complement of the universe’s gravitational waves exactly could take observatories out into the moon, to the atomic area and elsewhere.
