On a Saturday night at home while relaxing with friends, a dog showed up at the house. In an attempt to find the legal owner and return the dog, we knocked on the door of the legal owner and an old man opened the door. This was the start of an interesting week.

    The old man sat down, made himself at home, and gifted us the dog. After a brief visit, he left, and we were now the proud owners of this dog. It takes experience and knowledge to know that our lifestyle can't satisfy the needs of this dog; the owner that gifted us the dog was mismatched for him as well.

    Three attempts to return the dog to his old owner failed. (I think he was avoiding us.) Because our lifestyle didn't allow us to give this poor dog the attention he needed, he disturbed the neighbors. They got involved. After we shared the story, they gained a new perspective and wisely stepped in to help us find a solution.

    One week later it was decided that dog would be picked up from us by the old neighbor. He would then return it to the previous owner who was more equipped to care for it.

    When faced with unexpected challenges in life, it helps to see everyone's perspective. We have to look at one another's perspective to solve a problem with honesty, experience and knowledge. That's the sign of a leader. Although the old neighbor typically has little to do with leadership, it did bring a neighborhood together to understand one another and work as a team to solve a problem.

    Have you ever run into a careless cell phone user on the street? Perhaps they were busy talking, testing or checking updates on WeChat without looking at what was going on around them. As the number of this new “species” of human has kept rising, they have been given a new name — phubbers (低头族).

    Recently, a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities bury themselves in their phones. A doctor plays with his cell phone while letting his patient die, a pretty woman takes selfie in front of a car accident site and a father loses his child without knowing about it while using his mobile phone. A chain of similar events eventually leads to the destruction of the world.

    Although the ending sounds overstated, the damage phubbing can bring is real. Your health is the first to bear the effect and result of it. “Constantly bending your head to check your cell phone could damage your neck,” Guangming Daily quoted doctors as saying. “The neck is like a rope that breaks after long-term stretching.” Also, staring at cell phones for long periods of time will damage your eyesight gradually, according to the report.

    But that's not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends, many people tend to stick to their cell phones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported.

    It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cell phones in broad daylight.

    Scientists around the world are striving for effective detection of cancer in the early stages,which is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body,and a Chinese scientist may have found a quick way of knowing whether malignant tumors（恶性肿瘤）exist in a patient's body,with just one drop of blood.

    Malignant tumors in early phases can be cured.However,it's extremely difficult to be aware of cancer in its early stages,as patients don't show obvious symptoms and thus it can only be found in its later stages,which is already too late,so to detect cancer early remains a global challenge for scientists.

    Back in 1989,scientists have found a kind of heat shock proteins (HSP),named Hsp90α,which existed in human bodies and can be used as a cancer biomarker detection kit.Scientists around the globe have been working on it since then,and more than 10,000 journals have been published on accredited magazines,yet no one has actually turned their research results into medical products.

    However,Luo Yongzhang and his team in Tsinghua University's School of Life Sciences in Beijing seemed to have cracked the code,after working on the problem since 2009.The team has produced an artificial Hsp90α protein for clinical use that gains structural stability by regrouping proteins.The test kit can diagnose multiple kinds of cancer by analyzing a drop of human blood.This means they are able to "create" the protein,in any quantity,and at any time they wish to.

    The kit has since been used in clinical trials involving 2,347 patients at eight hospitals in China.It was the first clinical trial in the world to test if the protein could be a useful tumor biomarker for lung cancer,and it succeeded. Now,the kit has been approved to enter the Chinese and European markets,24 years after Hsp90α was discovered.

    Mobile Safety App Powered by LiveSafe

    The Mobile Safety App powered by LiveSafe, manage by the USC Department of Public Safety and the USC Department of Emergency Planning, is a free downloadable app that that mobile users can use to initiate contact with emergency responders around the campus. Features include: immediate “push button” calls to DPS, easy reporting for suspicious activity or crimes in progress, and location services to notify friends of your route through campus.

    Blue Light Phone Locations

    The University Park has multiple blue light phones that are strategically placed throughout campus. Take note of where the closest ones are on your route. They come in handy in case you lose your phone or in an emergency. These phones are directly connected to USC's Department of Public Safety's 24-hour communications center. Besides emergency needs, it can also be used to report suspicious activity, request for an escort (护送) if you feel unsafe and to report a crime.

    Trojans Alert

    Trojans Alert is an emergency notification system that allows university officials to contact you during an emergency by sending messages via text message or email. When an emergency occurs, authorized USC senders will instantly notify you with real-time updates, instructions on where to go, what to do (or what not to do), whom to contact and other important information. All members of the USC community, as well as parents and regular visitors to campus, are strongly encouraged to sign up for Trojans Alert.

    Mid-afternoon on a particularly busy Tuesday, I took leave of my desk at work and walked into a local Starbucks, only to find a space where neither my clients (客户) nor my children would ask me to do something.

    Inside, I ran into Kate, a co-worker of mine. The topic of parenthood came up. I complained about how packed my schedule was. From the minute I woke up to the minute I fell asleep, I was constantly in demand and always had someone knocking at the door. But a bit of sadness seemed to come over Kate's face.

    "Well, my daughter's in San Francisco and she doesn't seem to need me at all these days." Kate said. It was in that moment that I realized although I might often feel in high demand, there will come a day when I'll actually miss that same stress I now complain about.

    And as our conversation continued, it turned to our children's younger years, with Kate smiling proudly, thinking of the little boy and girl she raised who are now a man and a woman. But I noticed her smile was marked with regret. She explained that she often wondered about what she could have done differently when her children were in their earlier years.

    This got me thinking Is regret an unfortunate footnote (注脚) to parenthood? With that in mind, I asked six older parents one question: What is your biggest regret from your early days as a parent?

    It turned out that all of them thought they could have done it better. But, each of them also has a strong, healthy relationship with their kids. Whatever regrets their parents might have had about their upbringing, one thing is clear—it didn't affect them in a meaningful way.

    The bottom line is, we all feel like we could be doing this parenting thing better, And quite clearly, years later, we're still going to look back and wish we tried things differently. But the past can't be changed, and neither should it.
