    When it comes to climate change, there are always some new, terrifying consequences to worry about—like ancient viruses and bacteria coming from the ice as the earth warms. Unfortunately, researchers fear we may see more of this in the future.

    Some of these viruses and bacteria may have been trapped for thousands of years, and it's not even totally clear yet what they are, let alone what kind of damage they might have.

    Researchers have met complex “giant viruses” in the melting permafrost(永久冻土) of Siberia. One such virus, 30,000 years old, was still infectious when it was discovered in 2015, though it posed no danger to humans. It turns out that permafrost is excellent at preserving bacteria and viruses that are temporarily inactive, and then become reactivated with warming.

    Scientists have discovered Spanish flu viruses in dead bodies buried in 1918 in the Alaskan tundra (冻原). When close to half of the population of a Siberian town in the 1890s died of smallpox (天花), their bodies were buried in the permafrost along the Kolyma River. The banks of that river are now beginning to wear away amid global warming, the BBC reports.

    In Siberia in August 2016, some 100 people and 2,300 deer were infected with anthrax(炭疽) in the first outbreak in the area since 1941. One boy died from the disease. Scientist believed the anthrax had been trapped in the body of a long-frozen dead deer and became active during particularly hot summer of 2016, releasing the bacteria cells into the environment.

But even in warmer climates, rising temperatures can help grow and spread dangerous diseases. Over a decade ago, researcher Paul Epstein prophesied the possible spread of mosquito-born illnesses as a result of climate change. “Mosquitoes are sensitive to temperature changes,” he said. “Warming speeds up their rates of reproduction and the number of blood meals they take, makes their breeding (繁殖) season long, and shortens the maturation period for the germs they spread” — all of which makes them more efficient at spreading disease.

    Some people dream about becoming engineers. Luckily, the new IMAX film Dream Big shows how engineering can improve people's lives. It teaches viewers how engineers use high-tech to help the world. The film hits IMAX theaters nationwide on February 17 to celebrate Engineers Week.

    The film, taking place in locations like China, Dubai and Africa, tells the stories of engineers who try to come up with creative ideas to save energy and help people.

    Dream Big was directed by Greg MacGillivray who has 38 films under his belt, including some of the most successful films ever shown in IMAX theaters.

    How did MacGillivray get into the moviemaking business? “I grew up at the beach. My first movies were about surfing and the ocean. As time went on, I saw the changes in the ocean including polluting and overfishing. So I started making films about conservation of nature.” He told TFK. Now, his films cover a variety of topics, from the natural world to human creation.

    One of the engineers in Dream Big is Angelica Hernandez. In high school, she was on a team that best MIT, a university, in an underwater robotics competition. Today, the engineering work she does focuses on helping people use less energy and save money and resources. “I work with companies to promote energy efficiency with their commercial customers, so it's really trying to push forward all the measures that customers and high-energy users can apply, she explains.

    Engineering is such a good job-you make good money, travel around the world, solve amazing problems and help people.” She says.

    The mission of Dream Big is to show people the good that engineers can do to the world. “That was the impulse of making this movie”, MacGillivray explains, “We want to explain engineering in a way that will get the kids very excited about it.” “Whoever and wherever you are, you can become an engineer,” he adds, “All you need is the creative spirit.”

    A typical school day in the UK starts around 8:30 am. This is often even earlier elsewhere in the world, with students sitting down to their first lesson at 7:30 am in the US. The average teenager ideally needs eight to nine hours' sleep each night, but in reality a lot of teenagers struggle to get this much. A lot of the problems happen because our sleep patterns are not fixed, and they change as we grow.

    So a later school start time could help to solve this problem, by ensuring to get their eight plus hours of sleep and react properly to their body's natural rhythms(规律). There has been a general change over the past 25 years to shorten the school day. This is not at the cost of teaching time (which has remained constant) but at the cost of natural breaks, which has led to reduced lunch time and lesson breaks.

    Later start times could help teens' grades and health. This is mainly because it makes the management of children easier. Managing hundreds of children "playing" requires effective staffing. And there is always the fear that behavior worsens during breaks. So the theory goes that having them in class and strictly managed must be better.

    But this means that students barely have enough time to absorb what they were doing in maths before suddenly they are forced to study ancient history. And teaching staff also move through from one class to another, with hardly a rest or time to refocus.

    Clearly rethinking the school day could benefit everyone included. Anyway, it could also lead to better achievement in teenagers and less of a struggle for parents in the mornings. For teachers, it could also mean a less stressful day all around and what could be better than that?
