Airbags, now found in almost every vehicle, have saved countless lives and largely reduced the severity of injuries in crashes. Similar technology could greatly reduce broken hips (髋部) resulting from a fall, something most seniors fear.

    Dr. Robert Buckman and his start-up company, Active Protective in Allentown, Pennsylvania, has developed a promising solution, a wearable airbag that can protect hip bones in the event of a fall. The idea was the result of Dr. Buckman's years as a doctor at Temple University. He noticed how many elderly people were being brought into hospitals with broken hip due to falls, and how they often never completely recovered from the injuries. He started to ask what he could do for these people, and that was when he started trying to figure out whether there was a way of helping people who were at the highest risk of falling and suffering these kinds of injuries.

    The device is worn much like a regular belt, but on the outside of the clothing, and it includes sensors that monitor the movement of hips. If the device detects that the person, is falling, an airbag opens before the person hits the ground, cushioning the fall. When the wearer hits the ground, the bag reduces the force to the hip bones by 90 percent, enough to avoid the majority of hip injuries.

    With one out of every three people aged 65 and older suffering serious falls each year, Active Protective has a big market for its wearable device. It also has the potential to sizably reduce hip - related health care expenses: Hip injuries among the elderly cost the US health care system in 2012 $30 billion, which doesn't include the long-term care expenses associated with the high percentage of patients that can no longer live independently.

    What's more exciting than having a fresh hot pizza delivered to your door?  How about having it brought to you by a robot?  Thanks to Domino's Robotic Unit or DRU, that just became a reality! On March 8, the three-foot tall robot delivered its first pizza to some lucky residents in Brisbane, Australia.

    The fully autonomous DRU is the result of cooperation between Domino's Pizza Australia and Marathon Robotics. The 450-pound machine that travels at a maximum speed of 12. 4 miles an hour can traverse a distance of up to 12 miles and back, before requiring to recharge the battery. LIDAR, a laser-based sensor technology similar to the one used in self-driving cars, enables DRU to detect and avoid obstacles, while traditional sensors, much like those used in vacuum robots ensure its path is safe as it heads to its destination.

    The robot can fit up to ten pizzas and even has a separate cold area to accommodate drink orders. To access their food, customers have to enter the unique code provided for them by the company. This not only ensures that they pick up the right pizza, but also prevents the pies from getting stolen.

    Scientists expect additional DRU's to be ready for service in their various Queensland locations within the next six months. But don't expect these super cute robots to replace humans anytime soon. According to Domino's the DRU still needs extensive testing, which the company believes could take up to two years.

    And then there is also the issue of regulations. The public use of autonomous vehicles is still banned in most countries. But Don Meij, the CEO and Managing Director of Domino's Pizza Australia New Zealand Ltd, is not worried. He is“confident that one day DRU will become an integral part of the Domino's family. ”

    Snoring(打鼾) is noisy breathing during sleep. It is a common problem among all ages and it influences about 90 million American adults. People most at risk are males and those who are overweight, but snoring is a problem of both genders, although it is possible that women do not present this complaint as frequently as men.

    Snoring is often the loud or harsh sound that can occur as you sleep. You snore when the flow of air makes the tissue in the back of your throat vibrate(颤动) as you breathe. The sound most often occurs as you breathe in air, and can come through the nose, mouth or both two organs. It can occur during any stage of sleep.

    About half of people snore at some point in their lives. Snoring is more common among men, though many women snore. It appears to run in families and becomes more common as you get older. About 40 percent of adult men and 24 percent of adult women are habitual snorers. Men become less likely to snore after the age of 70.

    Sleeping on your back may make you more likely to snore. You may snore when your throat or tongue muscles are relaxed. And substances(物质) that can relax these muscles may cause you to snore. These include alcohol, muscle relaxants and other medicine.

    Snoring can be a nuisance to your partner and anyone else nearby. You may even snore loudly enough to wake yourself up. Though, in many cases people do not realize that they snore. Snoring can also cause you to have a dry mouth when you wake up.

    Light snoring may not disrupt your overall sleep quality. Heavy snoring may be connected with a risk factor in the heart disease, stroke and many other health problems. So never take it lightly.

    Patients with light or moderate depression can be successfully treated by swimming with dolphins, researchers said on Saturday.

    The study was carried out in Honduras, including patients who were thought by the doctors with light of moderate depression coming from the United States and Honduras.

    For two weeks, half of the group swam and snorkeled (潜泳) with dolphins for an hour a day. At the same time the other half group carried out the same type of water activities, but with the absence of dolphins. Researchers want to find out the influence of water and the natural setting.

    All the study volunteers didn't continue to take any drugs or psychotherapy ( 心理治疗) at least for weeks before the start of the study and did not take any drugs during the study, said the researchers from the division of clinical Psychiatry at t e the University of Leicester Medical School.

    By the end of the study, those people who swam with the dolphins had a greater average reduction in their depressive symptoms than those who did not.

    The researchers noted that the study supports the theory of biophilia, which thinks that human health and well-being depends partly on the human connection with the natural world. The findings appeared in the issue of the British Medical Journal.

    Coming from the Greek, biophilia means “love of life”, and it has been developed by biologists to reflect the humans' natural tendency to connect with nature and animals, leading to interactions and positive emotions that result in psychological treatment.

    Friends always ask why I, a middle-aged woman with no athletic talent, travel to perilous places—the jungles of Thailand or Borneo, for example, where the water is often unsafe and the food risky; places with infectious diseases, poisonous snakes and the wildest animals; some places where the locals are just a few generations past headhunting.

    I never know how to answer. My travel decisions assumed a new gravity nine years ago after I suffered a stroke. To prevent another stroke, my doctors told me, I'd have to take dangerously high levels of blood thinner (血液稀释剂) for the rest of my life and any travel would be risky.

    I had to think about what was important to me: family, of course, and friends. But then what? No matter how many times I thought about it, no bucket list was complete without travel. Then I had to decide how I might manage the risk. I had to decide how lucky I felt.

    My return to travel after my stroke came in baby steps. The first real test of my travel courage came nine months after my stroke when I joined my husband, Jack, on a business trip to China. After we'd toured the remains of a Tang dynasty temple on a high mountain, Jack wanted to ride down on a toboggan (长雪橇).

    Before the stroke it would've seemed like fun. But now? I hesitated. My mental klaxon (高音喇叭) screamed warnings about the consequences of a cut, a fall, and a crash. Then, gaining confidence from who knows where, I lowered myself carefully into the toboggan, which marked my adventure travel comeback.

    In the years since then, I've traveled about twenty-five percent of the time. Through it all, my lucks held out—no deadly falls, no car accidents or serious infections. For me, adventure travel is a risk worth taking. Travel broadens my world and keeps me connected to nature. What's more, saying "yes" to travel keeps me connected to myself.
