【推荐1】Hello! Wait! Don't run away. Yes, I know I am a roach. So, what's wrong with that?

You are speaking to the most successful species on the planet, you know! We've been around for 350 million years!

So what's the secret of our success? Sure, we've had plenty ofenemies. If you're small and full of protein, everything wants to eat you. So what did we do? We got quick, is what. We learned to hide, is what. We can squeeze so flat that we can fit through gap no bigger than a coin. Really! I dare you, try it.

And we never skip a meal! What do we eat? What have you got? Rotting leaves, garbage glue, paper, leather...and if you like to eat dead things, I tell you, the world is your refrigerator! But just don't offer me a cucumber or plastics!

Once humans came along, we went everywhere humans went. In ships, on planes, in camepacks across the desert Roach road trin! We even followed them to space! That's Uncle Anton. He hid on board the A pollo capsule — he was so mad when they just came right back to earth.

You can't have too many roaches. I say. Now there are 4.000 species of us: Asian, American. German... hope you get to meet them all someday.

Some of the family get pretty strange That's Reginald. He thinks if he pretends to be a firefly, birds won't oat him. That's tough old Ant Elo. She worked for some scientists trying to figure out ways to get rid of us ...ha! Poison, radiation, heat, cold…whatever they throw at us, we just get tougher. Bring it on!

Aw, look. that's me just after my 15 brothers and sisters and I hatched （孵化) out from egg case. Yeah. I look pretty much the same. That's another roach wonder — we skip the larva stage(幼虫期).Our eggs hatch all ready to roll! Still pretty cute, though.

Yep, that's how we got to be the most successful species on the planet!

【推荐2】Robbie Gay is a young boy with a massive heart. He had a terrible start to life, hospitalized twice with brain injuries before entering the foster (寄养的) home. When he was finally adopted by his parents, Maria and Charles, he was so frightened by his experiences that he was unable to cry.

However, the youngster found treatment in a most unlikely place — his local animal shelter. There he took comfort in caring for the older dogs who’d been left behind. When his mom Maria asked for his opinion, Robbie explained, “Because people don’t want older people and older dogs. They only want babies and puppies.”

His ability to empathize (共情) with the older dogs obviously comes from his own shocking experiences. He knows what it’s like not to be loved and cared for. Now in a safe and loving home environment, he’s able to open his heart completely to these unfortunate dogs. And it was this kindness that led him to find his own tears again when one of his foster dogs died.

Obviously, one of the difficulties in caring for these older dogs is that many don’t stay alive for long. But Robbie is insistent in staying with them right up until they pass away, as he quite rightly says, “I don’t think of when they’re going, I think of how they feel right now.”

Robbie is particularly unusual in that he not only wants to care for these aging dogs in their final moments, he also hopes to foster older people when he grows up. He is truly devoted to compassion and understanding, even if it leaves him heartbroken when his four-legged friends depart too soon.

Hopefully, Robbie will continue to change his negative experiences into caring for others. Through his beautiful heart, may he continue to heal and feel loved with his wonderful furry family, and his human one, too!

【推荐3】It is not always easy to understand animal behavior, especially when it’s related to other species (物种). For decades, researchers have observed orca (虎鲸) attacking and even killing porpoises (鼠海豚) in the Pacific Northwest. But it confuses people that these expert hunters don’t eat them. So what’s going on here?

Southern Resident orcas are a different population of orcas that live in the Pacific Northwest. The lives of these orcas are closely tied to those of the salmon (鲑鱼). So if the salmon disappear, so too will the orca. But despite their preference for salmon, these whales are known to attack and kill other smaller marine mammals (海洋哺乳动物)without eating them.

To better understand this unusual behavior, an international team of researchers did a research and examined more than 60 years of recorded interactions between Southern Resident orcas and porpoises in the Salish Sea.

“Why don’t the Southern Residents just eat porpoises instead?” Deborah Giles of Wild Orca said. “It’s because fish-eating killer whales have a completely different ecology and culture from orcas that eat marine mammals. So we must conclude that their interactions with porpoises serve a different purpose, but this purpose has only been a guess until now.”

According to Giles and her colleagues’ work, the orca may be attacking the porpoise as a form of social play. It is possible these large animals may be attacking the smaller mammals as a way to build up social cohesion (凝聚力). Similarly, the behavior could represent hunting practice, by which the orcas are practising their teamwork and cooperation skills for hunting salmon. Finally, the behavior could be a way of “mismothering” where the orca see the smaller porpoises as weaker or ill and so in need of care.

This work highlights the need for the protection of salmon populations in the area as well as the orcas’ entire hunting range. The threat (威胁) to the salmon’s future is not just a threat to a single species, but an entire ecosystem.

【推荐2】Recycling

Recyclable items are waste materials that can be processed to make new products. The recycled materials go through an intense process of separating the materials and converting into reusable products. At Waste Control, we offer a suite of on-site and off-site recycling services to meet the needs of our residential and business customers.

ON-SITE RECYCLING SERVICES

At the Waste Control facility, we have Drop-off Recycling and Buy-back Recycling Centers.

【推荐2】In business，there’s a speed difference:It’s the difference between how important a firm’s leaders say speed is to their competitive strategy and how fast the company actually moves.The difference is important regardless of industry and company size.Companies fearful of losing their competitive advantage spend much time and money looking for ways to pick up the speed.

In our study of 343 businesses，the companies that chose to go，go，go to try to gain an edge ended up with lower sales and operating incomes than those that paused at key moments to make sure they were on the right track.What’s more，the firms that “slowed down to speed up” improved their top and bottom lines，averaging 40% higher sales and 52% higher operating incomes over a three­year period.

How did they disobey the laws of business physics，taking more time than competitors yet performing better？They thought differently about what “slower” and “faster” mean.Firms sometimes fail to understand the difference between operational speed (moving quickly) and strategic speed (reducing the time it takes to deliver value).Simply increasing the speed of production，for example，may be one way to try to reduce the speed difference.But that often leads to reduced value over time，in the form of lower­quality products and services.

In our study，higher­performing companies with strategic speed always made changes when necessary.They became more open to ideas and discussion.They encouraged new ways of thinking.And they allowed time to look back and learn.By contrast，performance suffered at firms that moved fast all the time，paid too much attention to improving efficiency，stuck to tested methods，didn’t develop team spirit among their employees，and had little time thinking about changes.

Strategic speed serves as a kind of leadership.Teams that regularly take time to get things right，rather than plough ahead full bore，are more successful in meeting their business goals.That kind of strategy must come from the top.

The process is a less costly alternative to conventional 3-D printing with collagen, a key protein mainly existing in the mammal’s (哺乳动物) cells. Researchers in Assam, a state in India, are investigating using local silkworm species for the task—they recently submitted a patent for bioinks using a combination of proteins obtained from local silkworms. The scientists have woven them into tissue structures ranging from ears to heart.

Silk is a natural substance which is strong and completely biodegradable (可生物降解的), well suited for applications in tissue engineering. For instance, to bio-print an ear, researchers dissolve silk fibers. They carefully mix the sticky liquid with a patient’s stem cells, then build structures layer by layer with a 3-D printer. Finally, the cells grow and replace the silken proteins and finally change into a natural substance in human body.

Compared with common—used chemicals as adhesive (黏合剂), wild silk is also perfect to cross-link silky tissues, which helps to maintain a 3-D structure. Also, the wild silk has spots that cells naturally attach to, which allows cells to stick to the silk structure rapidly. “These silks are ideal candidates for bioinks because they can be combined to build strong human tissues” says Mandal, the lab’s lead investigator. “This is important, for example, when making bones,” he add.

“Obtaining and purifying collagen from animal remains is complex and expensive.” says David Kaplan, an expert in biomedical engineering, when asked about the advantages. Compared with collagen, silks have an immense advantage in terms of supply and processing. Local sourcing is also a clear plus in their use in India.”

Mandal and his colleagues have already created original structures, including bone and soft tissues of the heart and liver. Reconstructing a human knee complex tissue at the ends of a bone will be next.

【推荐2】Recognized as “The goddess scientist”, Ning Yan, 42, is a leading biology researcher at Princeton University in the US. On April 30, she was included among 100 new members and 25 foreign associates into The National Academy of Sciences, a famous scientific institution that to recognize out research in the US.

Yan is a rising star in the science world and her resume（履历）is impressive. After graduating from Tsinghua University and Princeton, she was invited to set up her own laboratory at Tsinghua in2007. At age 30, she became one of China’s youngest-ever female professors.

It was a long road to get where she is now. She told People magazine that she always believes that scientists need to have a pure mind and determination.

Yan likes to work at night, because she can focus when he outside is quiet. She also works at least 14 hours a day, but she’s energetic, because research is the most “comfortable” job for her, according to an interview with People magazine.

Yan also enjoys TV dramas and classic novels. Surprisingly, the novel Journey to the West inspired her to become a structural biologist. In the book, the Monkey King turns into other animals. She wondered what it would be like to change herself. Luckily, Yan now lives in that world every day, exploring how proteins work at the level of atoms. “It was almost destined（命中注定的）that I would become a structural biologist,” she said in an interview with Nature.

As she realizes her own dreams, Yan tries to encourage more women to follow careers in science. In her eyes, there is no difference between men and women in the scientific fields.

“Women can work as excellently as men and live the way they choose to,” she said in a public interview.
