    Wolves travel shorter distances and move slower during snowfall events, according to new research by University of Alberta biologists. The effects were most pronounced at night, when wolves hunt, and behaviour returned to normal within a day. Wolf tracks across snow in northeastern Alberta.

    "Our findings suggest that there is something about actively falling snow that causes wolves to slow down," said Amanda Droghini, a former MSc student in the Department of Biological Science and lead author on the study. "We don't know the exact mechanism behind that. It's unlikely that they were staying still because they were feasting on a recent kill. Instead, active precipitation(降雪量)might affect wolves' hunting abilities. Like rain, snow clears the air column of scent molecules. So, maybe falling snow makes it harder for wolves to detect the smell of prey."

    Over the course of two winters, the researchers used remote cameras to disclose snowfall events and estimate snow depth. To study wolf movement, they collected telemetry(测距仪) data from 17 wolves to calculate travel speed and duration, as well as resting periods. It is the first study to examine how large flesh-eating animals respond to snowfall events.

    With the effects of climate change on precipitation in the north forest region uncertain, it is difficult to predict the implications for wolf populations. Studies such as these increase our understanding of how large mammals react to normal snowfall events, but the type and amount of winter precipitation will likely have an impact on animal behavior and the energetic cost of movement.

    "Winter is already challenging for many wildlife species because moving through snow requires more energy. Snow can also make it harder for animals to access food resources," said Droghini, who conducted the research under the supervision of Professor Stan Boutin, Alberta Biodiversity Conservation Chair.

    "Anything that increases those costs, such as increased rain-on-snow events, could lead to lacking in nutrition, poor body condition, and even starvation as animals are unable to make up for those additional costs. That is one of the worst-case scenarios(设想)but, in truth, we know very little about potential changes to precipitation patterns and how wildlife will respond to those changes."

A、identify B、overlook C、overcome D、disturb
(2)、Increased precipitation might have the following effects on animals except _______.

    When most of us look at our hands, we might notice that we need to clean, or stop biting our fingernails, and that's about it. But if you ask a doctor, he can see a whole lot more. Everything from poor diet and stress to serious kidney (肾) problems can be revealed by a glance at your fingernails.

    There are about 30 different nail signs that can be associated with medical issues, though may indicate more than one problem, according to Dr. Amy Derick, a clinical instructor of dermatology at Northwestern University.

    Here are five of the things a doctor can tell about your health based on your fingernails.

    ⒈People who aren't eating well and lack vitamin or dietary may have thinner than normal nails, which are more likely to break.

    ⒉Horizontal lines are associated with serious physical stress. They frequently occur in people who have gone through chemotherapy(化疗).They can also occur after some illnesses, injuries, or with severe malnourishment(营养不良).Interestingly, there may be an altitude connection too. They've also been found in people who dove 1,000 feet and others who participated in an Everest exploration.

    ⒊Vertical lines, however, are generally not such a big deal. Some people are more genetically prone to them than others, but they're commonly associated with aging.

    ⒋When people lack iron, their nails can turn spoon-like. Instead of curving down and covering the finger normally, they'll start to rise up on the sides and front, like the part of a spoon that holds liquid.

    ⒌Kidney and liver problems can create “half-and-half nails”, where one part of the nail is white and the other part dark or pink, according to Derick.

    Doctors note that because disease diagnosis is complex and some symptoms can be associated with different diseases, you should always see a medical professional if you are concerned about something you notice.

    Mention the word superhero, and the images that come to mind are of fictional characters like Spiderman, Wonder Woman, or Batman. However, photographer Josh Rossi has used his camera to show the world's real superheroes — young children who are battling severe diseases and disabilities.

    The event leading to the creative project began in 2016, when Rossi fulfilled his then three­year­old daughter's dream of becoming Wonder Woman. Thanks to the handmade costume and Rossi's impressive Photoshop skills, the photoshoot instantly became a hit.

    Since it was Wonder Woman that brought about the idea, Rossi decided to focus on the superheroes that will appear alongside her in the upcoming movie, Justice League. To make the photo shoot more meaningful to the kids, he matched each child with a superhero with whom they had the most in common.

    The first member of the real­life "Justice League" was Kayden Kinckle. The five­year­old uses prosthetics (假肢) to walk because both his legs had to be cut off due to a born disorder. To Rossi, Kayden's perfect superhero was Cyborg, who was a healthy boy before a terrible accident left him injured, forcing his father to keep him alive with robotic parts.

    Teagan Pettit was born with only half a heart and has already gone through three open­heart surgeries. According to Rossi, the nine­year­old fits the bill for Superman because they both have a weak heart. The fictional superhero grows weak when near Kryptonite (氪), while Teagen's half heart is too weak to control his body temperature. The photographer says, "Superman and Teagan both have hearts of steel!"

    The latest data from the Office for National Statistics shows that one in every 12 kids is living in homes where no one has worked for at least a year. That may be due to unemployment or issues such as sickness or disability that mean they can't work, and aren't required to. This is known as being in a "long term workless" family.

    The issues faced by children in workless families have very bad influence on their development and education, limiting their future employment prospects, and reducing their opportunities to succeed throughout their lives.

    Not only does worklessness reduce family income, it can also damage families' health and stability, and thus destroy children's development. This is because many workless families are held back by disadvantages such as debt, drug and alcohol dependency, and by homelessness. Suffering from the family problems, many children face a greater and greater possibility of repeating the poor outcomes of their parents. Government research has shown that children in workless families are almost twice as likely not to reach the expected level at all stages of their education. For example, three-quarters of children from families where no one works failed to reach the expected level at General Certificate of Secondary Education (GCSE), compared to around half of children in lower-income working families.

    So attention should be paid to children in out-of-work homes. Having working parents means a child is more likely to do better at school, to have better health, education and development, and also means they are less likely to fall into crime.

    But for some families, worklessness, or not employment, is the norm. They just choose not to work. These families often face huge barriers to getting on with their lives but they take the opportunities offered by the society. Parents' ability to work is frustrated by issues like low skills or poor mental or physical health, or drug and alcohol dependency, leaving children without the stability they need.

    We all want to help workless families with complex problems so that their children can take advantage of the opportunities in Britain. We all want parents to have the chance to go out to earn a living and to enjoy the pleasure of work, so that their children can benefit from the good examples of working parents. In doing so, we should know the need to understand the complex issues that some families face and to develop a new approach to deal with poverty. Because the root causes are not financial. It is about helping families overcome the problems they face so that they can go as far as their talents and hard work will take them. We shouldn't retreat from acting to deal with disadvantages, because we know the costs of inaction to individuals, communities and society.

    Eating red meat is linked to cancer and heart disease, but are the risks big enough to justify giving up juicy burgers and delicious steaks? Probably not, according to researchers who reviewed data from 12 clinical trials involving about 54,000 people. In a series of controversial papers, the researchers argue that the increased health risks tied to red meat are small and uncertain, and that cutting back likely wouldn't be worth it for people who enjoy meat.

    Those conclusions go against established medical advice. They were swiftly attacked by a group of famous U.S. scientists who took the unusual step of trying to stop the papers from being published until their criticisms were addressed.

    The new work does not say red or processed meats like hot dogs and bacon are healthy, or that people should eat more of them. The team's reviews of past studies generally support the ties to cancer, heart disease and other bad health outcomes. But the authors say the evidence is weak, and that there's not much certainty meat is really the cause, since other diet and lifestyle factors could be at play.

    If the latest example of how divisive nutrition research has become, with its uncertainties leaving the door open for conflicting advice. Critics say findings often aren't backed by strong evidence. Defenders counter that nutrition studies can rarely be conclusive because of the difficulty of measuring the effects of any single food, but that methods have improved.

    Based on their analyses, the researchers said people do not have to cut back for health reasons. But they noted that their own advice is weak, and acknowledged that they didn't consider factors such as animal welfare and the environment. Indeed, the case that meat production is bad for animal welfare and the environment is stronger than the case that it's bad for human health, according to an editorial that accompanies the report.

    Not all of the report authors agreed with its conclusions. Three of the 14 researchers said they support reducing red and processed meats. A coauthor of one of the reviews is also among those who called for a publication delay.

    Those who pushed to postpone publication also questioned why certain studies were included in the reviews while others were left out.

    As for his own diet, Dr. Gordon Guyatt, a member of the international research team that conducted the reviews, said he no longer thinks red or processed meats have significant health risks. But he said he still avoids them out of habit, and for animal welfare and environmental reasons.
