Our risk of cancer rises dramatically as we age. So it makes sense that the elderly should be routinely screened for new tumors — or doesn't it?

    While such vigilant(警觉的) tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly. With the percentage of people over age 65 expected to nearly double by 2050, it's important to weigh the health benefits of screening against the risks and costs of routine testing.

    In many cases, screening can lead to additional biopsies(活检) and surgeries to remove cancer, which can cause side effects, while the cancers themselves may be slow-growing and may not pose serious health problems in patients' remaining years. But the message that everyone must screen for cancer has become so ingrained(根深蒂固的) that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a riotous reaction among doctors, patients and advocacy groups.

    It's hard to uproot deeply held beliefs about cancer screening with scientific data. Certainly, there are people over age 75 who have had cancers detected by routine screening, and gained several extra years of life because of treatment. And clearly, people over age 75 who have other risk factors for cancer, such as a family history or prior personal experience with the disease, should continue to get screened regularly. But for the remainder, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy(预期寿命).

    A recent study suggests that doctors start to make more objective decisions about who will truly benefit from screening—especially considering the explosion of the elderly that will soon swell our population.

    It's not an easy calculation to make, but one that make sense for the whole patient. Dr. Otis Brawley said, “Many doctors are ordering these tests purely to cover themselves. We need to think about the rational(合理的) use of health care and stop talking about the rationing of health care.”

    That means making some difficult decisions with elderly patients, and going against the misguided belief that when it comes to health care, more is always better.

Distance runners often worry about “hitting the wall” during training or races—that terrible moment when negative thoughts become so overpowering that they make it difficult to continue.

Hitting the wall typically happens around 20 miles in a marathon, when the body's supplies become exhausted. At this point, many runners feel exhausted and discouraged, slow their pace, have trouble focusing and want to quit or walk.

“Generalized tiredness, unintentionally slowing their pace, the desire to walk, and shifting focus to just surviving the marathon appear to be particularly common characteristics of it,” said Dr. Alistair McCormick, an exercise psychologist in England who co-authored a new study. “A marathon becomes a real mental battle when runners ‘hit the wall.'”

    Psychological blocks are an extremely common experience for recreational endurance (耐力) athletes, according to the study. To learn how they affect people, sports psychologists asked 30 recreational runners and cyclers about the psychological demands of training, preparing for and participating in competitions.

     “Recreational runners and cyclists found it stressful trying to find the time to train, McCormick said. “What was also interesting was the number of potential banana skins they met with before and during competition-disasters that could cause the athletes to lose their focus and their motivation to keep persevering.”

    These roadblocks included difficult environmental conditions and equipment failure, problems with nutrition or making a mistake, the study reported. The athletes in the study said they fell these obstacles (障碍) affected their motivation and concentration, negatively affecting their overall performance.

According to the study, 43 percent of marathoners are likely to hit the wall during a race. Finding ways to move past those kinds of experiences, then, could have major benefits for an athlete's performance and well-being.

    Stephen Hawking, the brilliant British theoretical physicist who published wildly popular books exploring the mysteries of the universe, has died, according to a family spokesman. He was 76.

    Considered by many to be the world's greatest living scientist, Hawking was also a cosmologist, astronomer, mathematician and author of numerous books including the landmark“A Brief History of Time,” which has sold more than 10 million copies.

    With fellow physicist Roger Penrose, Hawking combined Einstein's theory of relativity with quantum theory(量子理论) to suggest that space and time would begin with the Big Bang and end in black holes. He also discovered that black holes were not completely black but emit(释放) radiation and would likely eventually evaporate(蒸发) and disappear. “It will be difficult enough to avoid disasters on planet Earth in the next 100 years, let alone next thousand, or million. The human race shouldn't have all its eggs in one basket or on one plant. Let's hope we can avoid dropping the basket until we have spread the load.”

    Hawking suffered from ALS (amyotrophic latcral sclerosis), a disease which is usually fatal within a few years. He was diagnosed in 1963, when he was 21, and doctors initially gave him only a few years to live. The disease left Hawking wheelchair-bound and paralyzed. He was able to move only a few fingers on one hand and was completely dependent on others or on technology for everything—bathing, dressing, eating, even speech. “I have been lucky that my condition has progressed more slowly than is often the case. But it shows that one need not lose hope.” Dramatically, he even guest-starred in the “Star Trek”, “The Simpsons” and the 2014movie “The theory of Everything”.

    Hawking leaves behind three children and three grandchildren. “We are deeply saddened that our beloved father passed away today,” Hawking's children, Lucy, Robert and Tim, said in a statement. “He was a great scientist and an extraordinary man whose work and legacy will live on for many years. His courage and persistence with his brilliance and humor inspired people across the world. “We will miss him forever.”

    When hospital staff are in full scrubs (手术衣), their faces are almost completely covered by their caps and face masks, and we can only see their eyes and eyebrows. In order to solve the problem, a doctor in Sydney, Australia, called Rob Hackett launched a campaign named "Theatre (手术室) Cap Challenge"-encourage hospital staffs to write their' names and roles on their caps. At first, his colleagues didn't take it seriously. However, with time going on, it has been adopted around the world with studies from the US and UK reporting how this simple idea can decrease human errors in healthcare.

    "I went to a theatre where there were about 20 doctors and nurses in the room," Dr. Rob Hackett said. "I struggled to even ask to be passed some gloves because the person I was pointing to thought I was pointing to the person behind them, because I don't know their names." said Rob. As we all know, doctors are a stressful profession. When faced with life and death, they need to save the patient's life for a second. At the moment, effective communications are important.

    "The 'Theatre Cap Challenge' is in response to concerns about how easily avoidable mistakes and poor communication are contributing to rising harmful events for our patients." said Rob. "We need to develop systems which reduce mistakes and misunderstanding without causing harm. For this to happen, we need to let everyone know we're human." he added On the other hand, from the patients' viewpoint, caps with names on them can make patients more unworried. When everyone appears the same, it is extremely difficult to distinguish who is who. Knowing them relaxed.
