1 . You’ve heard that plastic is polluting the oceans — between 4.8 and 12.7 million tonnes enter ocean ecosystems every year. But does one plastic straw or cup really make a difference? Artist Benjamin Von Wong wants you to know that it does. He builds massive sculptures out of plastic garbage, forcing viewers to re-examine their relationship to single-use plastic products.
At the beginning of the year, the artist built a piece called “Strawpocalypse,” a pair of 10-foot-tall plastic waves, frozen mid-crash. Made of 168,000 plastic straws collected from several volunteer beach cleanups, the sculpture made its first appearance at the Estella Place shopping center in Ho Chi Minh City, Vietnam.
Just 9% of global plastic waste is recycled. Plastic straws are by no means the biggest source (来源) of plastic pollution, but they’ve recently come under fire because most people don’t need them to drink with and, because of their small size and weight, they cannot be recycled. Every straw that’s part of Von Wong’s artwork likely came from a drink that someone used for only a few minutes. Once the drink is gone, the straw will take centuries to disappear.
In a piece from 2018, Von Wong wanted to illustrate (说明) a specific statistic: Every 60 seconds, a truckload’s worth of plastic enters the ocean. For this work, titled “Truckload of Plastic,” Von Wong and a group of volunteers collected more than 10,000 pieces of plastic, which were then tied together to look like they’d been dumped (倾倒) from a truck all at once.
Von Wong hopes that his work will also help pressure big companies to reduce their plastic footprint.

2 . On Christmas Eve, a team of reindeer (驯鹿) will help Santa Claus deliver gifts to children all around the world. The reindeer, led by their fearless leader Rudolph, won’t be the only ones doing something special. Back in the highest Arctic, their cousins have a remarkable ability changing their eye color.
During the summer months, when the days are long and the sun is bright, reindeer’s tapetum lucidum (荧光膜), a mirror-like layer at the back of their eye, appears golden, which helps bounce the majority of light off the eyes, effectively acting like a pair of natural sunglasses. As winter comes, and the days become shorter and darker, the tapetum lucidum turns blue to absorb more light, allowing reindeer to improve their night vision and see clear in low light conditions.
With these adaptations, reindeer can adapt and thrive in one of the harshest environments on Earth. Unlike humans, reindeer can see well into the shorter Ultra Violet (UV) range. This UV vision enables them to spot food and predators more effectively in the snowy landscape. Lichens, a key part of their winter diet, absorb UV, so they show up dark against UV-reflecting white snow. Wolf and polar bear fur also absorb UV, so instead of disappearing against snow they pop out in high contrast, allowing reindeer to spot potential threats from a distance.
Reindeer change their eyes by adjusting their tapetum lucidum, which is made of collagen fibers. In winter, the collagen fibers become packed tighter, causing the tapetum lucidum to mainly reflect blue light. This change happens when reindeer dilate their pupils (瞳孔). In summer, the reindeer’s pupils return to a smaller size, which helps reindeer reduce the amount of light entering the eye.
But their unique adaptation may hurt them. Today, the increasing use of artificial lighting, especially during the winter months, poses a potential threat to their sensitive eyes. It can make reindeer lose their way, affecting their ability to survive in their challenging environment. So it is crucial for us to be mindful of our use of electricity and make efforts to minimize light pollution to ensure the well-being and survival of these magnificent creatures.

5 . Plastic is everywhere, from the Arctic ice to vital organs in the human body. In fact, previous estimates suggest that the average person swallows a credit card-worth of microscopic plastic particles(颗粒) every week. But new research shows that this could actually be an understatement.
Microplastics are plastics smaller than 5 millimeters, found in industrial waste, beauty products, and formed during the degradation of larger plastic pieces. Over time, they break down into even smaller nanoplastics. These tiny particles can pass through our intestines and lungs into our bloodstreams, reaching vital organs like the heart and brain.
While the idea of eating plastic is unsettling in itself, the major concern here is that these plastic particles contain chemicals that can interrupt our body’s natural release of hormones, potentially increasing our risk of reproductive disorders and certain cancers. They can also carry toxins(毒素) on their surface like heavy metals.
In the past, researchers have shown bottled water can contain tens of thousands of identifiable plastic fragments in a single container. However, until recently, only the larger microplastics were detectable with available measuring tools, leaving the area of nanoplastics largely a mystery.
Using Raman microscopy (显微镜学), capable of detecting particles down to the size of a flu virus, the team measured an average of 240, 000 particles of plastic per liter of bottled water, 90 percent of which were nanoplastics, a revelation 10 to 100 times larger than previous estimates.
These plastics likely originate from the bottle material, filters used to “purify” the water, and the source water itself. “It is not totally unexpected to find so much of this stuff, ” the study’s lead author, Columbia graduate student Naixin Qian, said in a statement. His team hopes to expand their research into tap water and other water sources to better inform our exposure to these potentially dangerous particles. “The idea is that the smaller things get, the more of them I reveal, ” he added.

6 . A new study by researchers at the University of British Columbia (UBC) and the University of Victoria has shown that common levels of traffic pollution can damage human brain function in only a matter of hours.
“For many decades, scientists thought the brain may be protected from the harmful effects of air pollution,” said senior study author Dr. Chris Carlsten. “This study, which is the first of its kind in the world, provides fresh evidence supporting a connection between air pollution and cognition.”
For the study, the researchers briefly exposed 25 healthy adults to diesel exhaust (柴油废气) and filtered air at different times in a laboratory setting. Brain activity was measured before and after each exposure using functional magnetic resonance imaging (fMRI).
The researchers analyzed changes in the brain’s default mode network (DMN), a set of inter-connected brain regions that play an important role in memory and internal thought. The fMRI revealed that participants had decreased functional connectivity in widespread regions of the DMN after exposure to diesel exhaust, compared to filtered air.
“We know that altered functional connectivity in the DMN has been associated with reduced cognitive performance and symptoms of depression, so it’s concerning to see traffic pollution interrupting these same networks,” said Dr. Jodie Gawryluk, a psychology professor at the University of Victoria and the study’s first author. “While more research is needed to fully understand the functional impacts of these changes, it’s possible that they may impair (损害) people’s thinking or ability to work.”
Notably, the changes in the brain were temporary and participants’ connectivity returned to normal after the exposure. Dr. Carlsten assumed that the effects could be long lasting where exposure is continuous. He said that people should be mindful of the air they’re breathing and take appropriate steps to minimize their exposure to potentially harmful air pollutants like car exhaust.

8 . Noise pollution has a long-term effect on tree populations that may persist even after the sources of noise are removed, according to research published Wednesday.
Man-made noise from industry and the building of infrastructure such as roads and pipelines has increased greatly since the middle of last century. While previous research has documented the short-term effect noise has on tree populations as it scares off pollinators (传粉者) such as insects and animals, few studies have covered the long-term effect.
Researchers in the United States looked at tree populations in New Mexico that had been “hearing”a high level of man-made noise for 15 years. They found 75 percent fewer pinyon pine seedlings (矮松苗) in noisy places than quiet ones.
Then they looked at other places in New Mexico, where sources of noise had recently been added and then removed, and examined how populations recovered. The team assumed that populations of the trees — in this case pinyon seedlings — would recover as the pollinators would return to the places once the noise had disappeared. Instead, they found a long-term drop in seedling numbers as the birds refused to revisit the places.
“The effects of human noise pollution are growing into these woodland communities,” said Clinton Francis, lead researcher from California Polytechnic State University. “What we’re seeing is that removal of the noise doesn’t necessarily immediately result in a recovery of ecological function.”
Jennifer Phillips, co-author of the research, said the findings showed how the effect of noise pollution could put pollinators off even after the noise is removed. “Animals like the birds that are sensitive to noise learn to avoid particular areas.” said Phillips. “It may take time for animals to come back to pollinate trees in these previously noisy areas, and we don’t know how long that might take.”
As governments continue to face growing evidence of the damage to nature caused by urbanization (城市化), Phillips held that the influence of noise pollution should also be factored into planning decisions.

9 . The increased use of light-emitting diodes (LED) and other forms of lighting are now brightening the night sky at a dramatic rate. Research has revealed that light pollution is now causing the night sky to brighten at a rate of around 10% a year, an increase that threatens to ruin the sight of all but the most brilliant stars in a generation. A child born where 250 stars are visible at night today would only be able to see about 100 by the time they reach 18.
Physicist Christopher Kyba, of the German Centre for Geosciences told the Observer. “A couple of generations ago, people would have regularly encountered this glittering (闪耀) vision of the universe—but what was formerly universal is now extremely rare.” Nevertheless, the introduction of only a modest number of changes to lighting could make a considerable improvement, Kyba argued. These moves would include ensuring outdoor lights are carefully capped, point downwards, have limits placed on their brightness, and are not predominantly blue-white but have red and orange components.
The problem is that light pollution is still not perceived by the public to be a threat. As Professor Oscar Corcho, of Universidad Politécnica de Madrid, has put it: “The negative consequences of light pollution are as unknown by the population as those of smoking in the 80s.”
Yet action is now urgently needed. Apart from its astronomical impact, light pollution is harming human health. “When reddish light shines on our bodies, it stimulates mechanisms including those that break down high levels of sugar in the blood. Since the introduction of LEDs, that part of the spectrum (光谱) has been removed from artificial light and it is playing a part in the waves of obesity (肥胖) and rises in diabetes cases we see today,” said Prof Fosbury from University College London (UCL),
UCL researchers are preparing to install additional infrared (红外线) lamps in hospitals and intensive care units (ICU) to see if they have an effect on the recovery of patients who would otherwise be starved of light from this part of the spectrum.

10 . Rain is vital to life on Earth. However, rain isn’t just made of water anymore—it’s partly made of plastic.
Millions of tiny pieces of plastic, called microplastics, are wandering around Earth’s atmosphere and traveling across entire continents, according to a study published in the journal Proceedings of the National Academy of Sciences on April 12. Another study, published in the journal Science in June 2020, has revealed that every year more than 1,000 tons of the particles (颗粒)—equivalent to over 120 million plastic bottles—fall in rain.
Microplastics are plastic particles less than 5 millimeters in diameter (直径) and come from a number of sources. Plastic bags and bottles released into the environment break down into smaller and smaller bits. Some microplastics are manufactured deliberately to provide abrasion (研磨) in a host of products, such as toothpaste and cleansers, according to the Daily Mail. Another major source is your washing machine. When you wash synthetic (合成的) clothing, tiny microfibers get flushed (冲掉) away with the wastewater. Even though the water is treated by a wastewater plant, the microplastics remain, and they are released into the sea, according to American magazine Wired.
Plastic rain may remind people of acid rain, but the former is far more widespread and harder to deal with. The tiny particles, too small to be seen with the naked eye, are collected by the wind from the ground. They are so light that they stay in the air to be blown around the globe. As they climb into the atmosphere, they are thought to act as nuclei (核心) around which water vapor (水蒸气) condenses (凝结) to form clouds. Some of the dust falls back to land in dry conditions, while the rest comes down as rain, according to the Daily Mail.
Microplastics have been found everywhere you can imagine. From fish and frogs to mice and mosquitoes, their bodies have been found, on average, to contain 40 pieces of microplastic, reported Daily Mail. As the top of the food chain, humans are exposed to microplastics, too. “We live on a ball inside a bubble,” microplastic researcher Steve Allen at University of Strathclyde, Scotland, told Wired. “There are no borders, there are no edges. It (plastic rain) raining on the land and then getting blown back up into the air again, to move somewhere else. There’s no stopping it once it’s out.”
