Kangaroos have long been a nuisance to many Australian farmers. Keeping these kinds of animals away from their crops and water supplies has become a continuous fight. A traditional way has been a series of the huge screaming (尖叫) from loudspeakers. Researchers have found that kangaroos often become used to these man-made sounds and take little notice of them.

Australian farmers could be about to get an unusual new weapon (武器) to protect their crops from kangaroos. Researchers in Melbourne have found that kangaroos can be frightened away by the loud sound of their own large feet. It appears to be quite a breakthrough. This is the noise these animals make when they feel danger before running away quickly. Using the animals' own alarm system could be what angry farmers have been looking for.

Animal rights protectors are happy about this new finding. When people complain that the number of kangaroos has risen quickly, they see that a large number of kangaroos have been killed or injured on Australian roads by cars and trucks. Also, they don't want several million to be shot dead every year by human beings. Researchers, who are hoping to develop their footstep sound technology, believe it could also be used to lead kangaroos away from busy highways. The protectors are in favour of this solution which can prevent kangaroos from being harmed and also please the farmers.

    Asking a patient to hum(哼唱)piano tunes and play fin instrument while undergoing brain surgery(手术)may sound like a strange request from a doctor．However，that is exactly what a team of brain specialists，led by Pilcher，requested Dan Fabbio to do．

    In 2015，the then 25-year-old musician was diagnosed with a brain tumor(肿瘤)，which was located in the part of the brain known to be active when people listen to and make music．“Removing a tumor from the brain can have significant consequences depending on its location，”Pilcher says．“Both the tumor and the operation can damage tissue and affect communication between different parts of the brain．”

    Fabbio，therefore，feared the surgery would cause him to lose his musical ability．To prevent that from happening，Pilcher and his colleague designed many tests，including asking Fabbio to listen to piano tunes and hum back during MRI scans．This enabled the physicians to locate the area that is vital for music and language processing and create a 3-D map of Fabbio's brain．

    Despite the great starting point，it was not a perfect way to prevent possible damage to the．The only way was to keep the patient awake and ask him to hum piano tunes during the surgery so that the surgeons could identify the areas to avoid．While the surgery went smoothly，the real test came when Fabbio was asked to play a song on his saxophone．The tunehad been simplified to ensure that it would not require too much strength and cause harm to the stitches(缝线)in the brain．He played it faultlessly，and when he finished，the entire operating room erupted in applause．

    The researchers say that a year after the groundbreaking surgery，the young musician can once again hear tunes in everything—even his electric toothbrush．

Serious measures are needed to make the people in Oman fitter, healthier and rid of the several factors that cause overweight and obesity (肥胖). According to Dr Noor al Busaidi, obesity is a global problem, not only in Oman and the MENA region but around the world, too. The prevalence (普遍) of obesity has been increasing steadily over the past 20-30 years. In Oman, the latest survey conducted by the Ministry of Health together with the World Health Organisation has revealed that overweight and obese people has reached 66 per cent in Oman, of which female obesity accounts for 40 per cent.

She further explained that those with a BMI (Body mass index) of 30 and above can be termed as obese while those with a BMI of 25-29.9 can be termed as overweight. Research shows that over 200 various diseases and health conditions including 30 types of cancer, diabetes, hypertension, heart disease, etc are associated with obesity, she said, adding, "Obesity is the mother of all diseases, hence it is necessary for people in Oman to watch their weight and take corrective measures."

"Over the last few years, the World Obesity Federation has also been stressing on obesity- related abuse and laughter. People tend to tease obese people without realizing that many people become obese for reasons beyond their control, like genetic factors or following an accident," Dr Noor said, adding that we need to fight discrimination against obese individuals in society.

Lastly, Dr Noor emphasized that health is not just the responsibility of the Ministry of Health and that concerted efforts are necessary from the government institutions, non-governmental organizations and individuals in society to make the nation healthy.

    When it comes to mental illness, many people often find it tough to get the help they need. This is especially true for young students making the transition(过渡) to college life.

    “Sometimes, students don't realize how hard it is to adjust to college,” said Laura Smith, associate dean of students at the University of Texas at Dallas. “You're not the big fish in your classes anymore; you have all kinds of personal stress; you're away from home. Dealing with these things is not easy.”

    Students who are going through these problems sometimes want to reach out. But if students don't feel comfortable seeking help, many feel that it's the responsibility of their university to help them.

    “I really wish that there was more importance placed on how counseling(咨询) centers help students,” said Comnie Trinh. “Counseling services are just as important as academics and sports.”

    Trinh, 27, graduated from Texas Woman's University in 2015. During college, she hosted various workshops on how to handle mental health conditions. Trinh used her own story to connect with students who might be facing similar problems. High academic pressures, cultural differences as an Asian American and stressful social situations stood out as some of the most common causes of Trinh's anxiety.

    It was only after years of personal problems that she could admit that reaching out isn't a sign of weakness.

    ”If you feel you can't connect with other people around you, you should address the issue without shame,” Trinh said. “You'll find that there are a lot of people out there who sincerely want to help you.”

    Have you ever lost your direction? Then you might find satellite navigation(satnav) systems(卫星定位系统) helpful.

    A satnav system uses groups of satellites. They send information to a receiver(接收器), such as your smartphone. Then they can find where you are.

The earliest satnav system is the Global Positioning System(GPS) of the United States. The US has put 24 satellites into space to make sure GPS can locate(定位) a person correctly and globally. Likewise, Russia's GLONASS and European Union's Galileo can also work globally.

    But China is catching up, building its own BeiDou Navigation Satellite System. BeiDou is China's homegrown satnav system, reported Xinhua. It was set up in 2000, when China sent BeiDou's first navigation experiment satellite into space. With it, China became the third country to build a satnav system after the US and Russia.

    BeiDou can find you wherever you are. It helps you go faster by finding shortcuts(捷径) and using correct directions. When you are in trouble and call the police, they will know exactly where you are if you have a cellphone that uses BeiDou.

    Today, there are more than 20 BeiDou satellites above our heads. And the system is able to offer open services to the Asia-Pacific region(亚太地区).

    In November, China plans to send more BeiDou-3 satellites into space. BeiDou-3's position accuracy(准确度) is less than five meters, Ran Chengqi, a senior designer of the satellite navigation system, told China Daily.

    By 2020, BeiDou is planned to have 35 satellites and begin serving globally, reported Xinhua.
