“We haven't found anything that we can't recycle!”

    Cigarette ends are everywhere—littering our streets and beaches—and for decades they've been thought of as“unrecyclable”. But a New Jerseybased company, called TerraCycle, has taken on the challenge, and has come up with a way to recycle millions of cigarette ends and turn them into industrial plastic products. Its aim is to recycle things that people normally consider impossible to reuse.

    Obviously it would be even better for the environment if everyone just stopped smoking, but the statistics show that although there has been an increase in anti-smoking ads and messaging, between 2000 and 2014, global sales of cigarettes increased by 8 percent, and a whole lot of those cigarette ends are ending up as trash. Since most of our litter eventually ends up in waterways, cigarette ends can surely pollute the surrounding environment. “It only takes a single cigarette end to pollute a liter of water, ” TerraCycle founder, Tom Szaky, said. “Animals can also mistake littered cigarette ends for food.”

    So how do you go about turning all those poisonous ends into something useful? TerraCycle does this by first breaking them down into separate parts. They mix the remaining materials, such as the tobacco and the paper, with other kinds of rubbish; and use it on non-agricultural land, such as golf courses. The filters (过滤嘴) are a little harder. To recycle these, TerraCycle first makes them clean and cuts them into small pieces, and then combines them with other recycled materials, making them into liquid for industrial plastic products.

    They're now also expanding their recycling offerings to the rest of the 80 percent of household waste that currently can't be recycled, such as chocolate packaging, pens, and mobile phones. The goal is to use the latest research to find a way to stop so much waste ending up in landfill (垃圾填埋), and then get companies to provide money for the process. And so far, it's working.

    “We haven't found anything that we can't recycle,”communications director of Terra Cycle, Albe Zakes, said. “But with the amount and variety of packaging and litter in the world, we are always looking for new waste streams to address.”

    Can exercise during childhood protect you against memory loss many decades later?Exercise early in life seems to have lifelong benefits for the brain,in rats at least.

    "This is an animal study,but it shows that physical activity at a young age is very important一not just for physical development,but for the whole lifelong track of cognitive（认知的）development during ageing,"says Martin Wojtowicz of the University of Toronto,Canada."In humans,it may delay the appearance of Alzheimer's symptoms（阿兹海默氏症）,possibly to the point of preventing them."

    Wojtowicz's team divided 80 young male rats into two equal groups,and placed running wheels in the cages of one group for a period of six weeks.Around four months later—when the rats had reached middle age—the team taught all the rats to connect an electric shock with being in a specific box.When placed in the box,they froze with fear.

    Two weeks later,the team tested the rats in three situations: exactly the same box in the same room,the same box with the room arranged differently,and a completely different box in a different room.

    The rats without access to a running wheel when they were young now froze the same percentage of times in each of these situations,suggesting they couldn't remember which one was dangerous.But those that had been able to run in their youth froze 40 to 50 percent less in both changed box settings.

    “The results suggest the amount of physical activity when we're young,at least for rats,has influence on brain and cognitive health—in the form of better memories—when we're older,"says Arthur Kramer of Northeastern University in Boston,who has found that,in humans,exercise promotes the growth of new brain cells.

    Only￡695 per child!

    More than one billion young people risk damaging their hearing through the overuse of smartphones and other audio devices, the UN warned Tuesday, proposing new safety standards for safe volume levels.

    Currently, about five percent of the global population, or some 466 million people, including 34 million children, suffer from disabling hearing loss. Young people are particularly likely to develop such risky listening habits. Around half of those between the ages of 12 and 35, or 1.1 billion people, are at risk due to "long and severe exposure to loud sounds, including music they listen to through personal audio devices," the UN health agency said.

    In a bid to safeguard hearing, the World Health Organization and International Telecommunications Union issued an international standard for the manufacture and use of audio devices. WHO considers a volume above 85 decibels for eight hours or 100 decibels for 15 minutes as unsafe. The safe listening devices and systems standard calls for a "sound allowance" software to be included in all audio devices, to track the volume level and duration of a user's exposure to sound, and to evaluate the risk posed to their hearing. This system could alert a user if they have dangerous listening habits.

    WHO is also calling for parental as well as automatic volume controls on audio devices to prevent dangerous use. While some smartphones and other audio devices already offer some of these features, the UN would like to see a uniform standard used to help protect against disabling hearing loss.

    "Think of it like driving on a highway, but without a speedometer in your car or a speed limit," Shelly Chadha of the WHO told reporters in Geneva. "What we've proposed is that your smartphones come fitted with a speedometer, with a measurement system which tells you how much sound you're getting and tells you if you are going over the limit".

My, what a big beak you have!

For humans, adapting to climate change will mostly be a matter of technology. More air conditioning, better-designed houses and bigger flood defenses may help to make the effects of a warmer world less harmful. {#blank#}1{#/blank#}In a paper published in Trends & Evolution, a team led by Sara Ryding, a PhD candidate at Deakin University, shows that is already. happening. Climate change is already changing the bodies of many animal species: bigger beaks (喙), limbs and ears.

In some species of Australian parrot, for instance, beak size has increased by between 4% and 10%since 1871. Another study, this time in North American dark-eyed juncos, another bird, found the same pattern.{#blank#}2{#/blank#}.

All that is perfectly consistent with evolutionary (进化) theory, "Allen's rule". Allen suggested it in 1877, holding that warm-blooded animals in hot places tend to have larger body parts than those in temperate (温带的) regions.{#blank#}3{#/blank#}Being richly filled with blood vessels (血管), and not covered by feathers, beaks make an ideal place for birds to get rid of heat.

Ms. Ryding examined museum specimens (标本) to prove that climate change was the cause of an anatomical (解剖学的) changes. All sorts of other factors might have been driving the changes. Her team combined data from different species in different places. They have little in common apart from living on a warming planet.{#blank#}4{#/blank#}.

For now, at least, the increase is small, never much more than 10%{#blank#}5{#/blank#}Since any evolutionary adaptation comes with trade-offs (妥协), it is unclear how far the process might go.

A. Therefore, climate change is the most reasonable explanation.

B. That may change as warming accelerates (加速).

C. Animals will have to rely on changing their bodies or their behaviors.

D. It seems that the future world is going to be hotter than humans are used to.

E. Therefore, the negative effects of a warmer world are visible in these animals' bodies.

F. Such adaptations boost an animal's surface area relative to its body, helping it to release extra heat.

G. Similar trends are seen in mammals, with species of mice and bats evolving bigger ears, legs and wings.
