1 . One debate about chicken eggs is why white eggs usually cost more than brown ones. Some people think white eggs are more nutritious (有营养的). Is that true? According to Sherman Hickman, the director of community outreach and education for Hickman’s Family Farms, it’s first important to know why chickens have different egg colors.
Jesse LaFlamme is the CEO of Pete and Gerry’s Organic Egg. She says, the chicken breed (品种) decides whether or not hens have pigment genes, the natural chemical that results in a colored shell. Although all eggs start out white in color, shell color can change from white to brown and even blue in some rare breeds. An interesting way to know what color eggs a hen lays is to look at the color of its ear feathers (羽毛), LaFlamme says. Breeds such as the Leghorn chickens lay white eggs, while Orpington chickens lay brown eggs and Ameraucana chickens produce blue eggs.
Hickman notes that the Leghorn breed is a popular choice for farmers because it lays more eggs. Hens that produce colored eggshells, however, usually are larger and require more feed and energy to create that painted shells. Since those breeds cost more to feed, their eggs are more expensive.
Although eggs sometimes look different and are priced differently, it’s impossible to know their nutrition according to shell color alone. “Choosing between brown and white eggs is a matter of personal preference,” Malina Linkas Malkani, media spokesperson for the Academy of Nutrition and Dietetics, says. “But it’s important for people to know that the color of the eggshell is related to the breed of the hen, not the egg’s nutrition, quality or shell thickness.” What does affect the nutrition is the specific food the hen eats, according to Malkani.

6 . To study the behavior of wild animals, scientists routinely tag them with solar-powered GPS location trackers. But such devices’ battery capacity limits how long they operate, often bringing a nearly end to vital conservation work. Solar-powered trackers break easily, making them a poor choice for devices fastened to larger mammals and they don’t work for night creatures.
So biologist Rasmus Worsoe Havmoller of the University of Copenhagen and his colleagues turned to another abundant power source: kinetic energy generated by an animal’s movements. It is also lighter and cheaper to make than its battery-powered counterparts (对应的事物). “The design is creative and exciting,” says Mark Hebblewhite, a habitat ecologist at the University of Montana. The proof-of-concept kinetic tracker works by means of a magnetic pendulum (摆钟) that swings around a copper coil, generating electricity as it moves.
Their kinetic tracker, which Havmoller’s team recently tested on domestic dogs, a wild pony and a European bison, could theoretically survive for the entire lifespan of an active animal. The dogs and the bison in the study were active enough to create the energy to transmit one location signal per day for 14 days and 17 days, respectively. However, one of the less active wild pony’s trackers lasted at least 146 days but didn’t produce enough power for daily transmissions, the researchers reported in PLOS ONE. The limited power generated by the animals’ movements means the technology isn’t ready for primetime just yet, says ecologist Emily Studd of British Columbia’s Thompson Rivers University, who wasn’t involved in the study.
When researchers want to keep close tabs on animals, they often need GPS fixes more than once a day. But Studd says that “with a bit more development, this could be a game changer for wildlife animal research and monitoring.”
Rasmus and his colleagues hope conservation workers can one day use this technology to track species such as tigers, leopards and wolves, which can easily destroy solar-powered trackers and which hunt and travel at night.

7 . Chinese scientists have collected seeds of several plants at a height of about 6,200 meters above sea level on the world's highest peak—Mount Qomolangma and will permanently preserve them in a place where seeds can be kept alive for as long as thousands of years.
The seed haven, namely the Germplasm (种质) Bank of Wild Species (GBWS), is located in an ordinary four-story building in a research institute in Kunming, Yunnan Province.
As the genes of most plants are contained in their seeds, germplasm resources have become the carriers of plants' genetic information. A seed bank serves as the most important facility for preserving such resources.
The fast loss of biodiversity and germplasm resources is the main reason for the establishment of seed banks around the world. Construction of the germplasm bank in Kunming started in 2004, and it was put into operation three years later.
“Wildlife germplasm resources have great application potential in the biological industry, attracting global attention, especially for the collection and preservation of wild plants,” said a researcher. Currently, seeds can only be accepted by the GBWS if they tick at least one of the three boxes: endangered, endemic (特有的) or “of economic importance”.
The long-term conservation of a seed is a complex procedure, involving more than 70steps, at the end of which the seed will be stored at -20℃. If properly stored, the seed could theoretically stay alive for decades or even thousands of years.
“When a species is destroyed by natural disasters, we will activate these seeds and bring the species to life,” said Li Dezhu, director of the seed bank.

8 . It seems that some people go out of their way to get into trouble. That’s more or less what happened on the night when Nashville Police Officer Floyd Hyde was on duty.
“I was on the way to a personal-injury accident in West Nashville. As I got onto Highway40, blue lights and sirens (警笛) going, I fell in behind a gold Pontiac Firebird that suddenly seemed to take off quickly down the highway. The driver somehow panicked at the sight of me. He was going more than a hundred miles an hour and began passing cars on the shoulder (路肩).”
But Hyde couldn’t go after him. Taking care of the injured people is always more important than worrying about speeders, so the officer had to stay on his way to the accident. But he did try to keep the Firebird in sight as he drove, hoping another nearby unit would be able to step in and stop the speeding car. As it turned out, keeping the Firebird in sight was not that difficult. Every turn the Pontiac made was the very turn the officer needed to get to the accident scene.
Hyde followed the Pontiac all the way to his destination. At that point he found another unit had already arrived at the accident scene. His help wasn't needed. Now he was free to try to stop the driver of the Firebird, who by this time had developed something new to panic about.
“Just about that time,” Hyde says, “I saw fire coming out from under that car, with blue smoke and oil going everywhere. He’d blown his engine. Now he had to stop.”
“After I arrested him, I asked him why he was running. He told me he didn't have a driver’s license.”
That accident cost the driver of the Firebird plenty — a thousand dollars for the new engine — not to mention the charges for driving without a license, attempting to run away, and dangerous driving.

My son David was injured in his forehead so I had to take him to a hospital. I looked around the crowded waiting room in the hospital and sighed. I thought, “Will the doctor be able to see my eight-year-old son soon?” I tried steadying the ice pack (冰袋) over his forehead, but it was no use. I couldn’t stop shaking. The injury in his forehead was deep, but at least blood wasn’t pouring from it anymore.
His face was full of tears, but he seemed really brave for his age. I handed him the ice pack, and he covered his forehead with it. He was doing a much better job than I had. We were at the hospital because another child had thrown a rock at David during a break between classes as he was running around the corner. His teacher called me, and when I arrived, I found him sitting in front of her. His teacher was caring for his injury, trying to keep him calm. She felt terrible about what had happened, but I knew none of it was her fault.
David received four stitches (缝线) and didn’t cry once throughout the whole treatment. For the next two days, his forehead was swollen and black and blue. I felt like I’d had a mini nervous breakdown. Every time I tried to sleep or tend to housework, horrible thoughts crept into my mind. Fear had taken over, and then the fear turned to anger. I was angry with the child who’d thrown the rock. I just couldn’t shake it. What was she thinking? She should have known about that better.
David’s headmaster and teacher called me that evening to see how David was feeling and told me Cherry, the girl, felt terrible. I wanted to stand up for my son, do the right thing and protect him.
The next day, David’s teacher stopped by to see how David was feeling and dropped off a get-well card that Cherry had made. David and I read it several times, and I couldn’t help but feel a little choked up. It was a sincere apology.
