1 . Voters in Colorado narrowly approved an initiative (计划), setting the stage for the return of gray wolves, which were wiped out in this area by the 1940s. This is the first time that a state has reintroduced an animal like this.

The Colorado Parks and Wildlife department will lead the effort to establish a sustainable population of gray wolves in the western part of the state, beginning in 2022 or 2023. The Southern Rocky Mountains, where there used to be a lot of them, contain millions of acres of suitable habitat that could support several hundred wolves or more, biologists say.

However, some say it’s unwise to leave the question to voters. “State biologists have previously declined to introduce wolves. There's a reason it's never been done before.” says Shawn Martini, spokesperson for Coloradans for Protecting Wildlife, noting that most supporters are from urban areas and they don't have to live alongside the animal, unlike people living in the countryside. Farmers and hunters don't favor the initiative, either. Farmers worry wolves will kill their cattle while hunters worry they will lose elk (驼鹿) to the predators.

On the other hand, according to Jonathan Proctor, a conservationist with the Defenders of Wildlife, reintroducing wolves will restore Colorado's natural balance. They help thin out sick animals, maintaining healthy populations of deer and elk. The remains of wolf kills also provide food for “eaters of the dead”, including wolverines, eagles, and bears. He also emphasizes the experience of living with wolves in other places, like the Northern Rockies, has shown that wolves are not the threat people sometimes make them out to be. Reintroduction program biologists promise to make it a priority to work with people living alongside wolves, providing training and resources to keep the wolves out of the farms in the first place. And a program will be funded to pay farmers for their lost cattle.

4 . China's historic 23-day Chang'e 5 mission has not only obtained precious rock and soil samples from the moon, but has also brought back a group of seeds that traveled the furthest in the nation's agricultural and forestry histories. More than 30 kinds of seeds, including that of rice, oats etc., were placed inside the multi-module Chang'e 5 spacecraft and orbited around the moon for about 15 days.

Scientists wished to check what would happen to the seeds after being exposed to extraterrestrial (地外的) forces in lunar orbit and also hoped that they could develop beneficial mutations (突变). This mission offered good opportunities to scientists, which enabled them to deepen their studies on the effect of cosmic rays on the growth and evolution of life on Earth.

Space-based mutation breeding refers to the process of exposing seeds to forces such as microgravity, vacuums and cosmic radiation during a spaceflight and then sending them back to Earth for further observation and planting. Researchers observe and examine several generations of plants grown from space-bred seeds and investigate their mutations-some are positive and desirable while others are negative. Those with positive mutations will be kept and analyzed, and will be introduced to farmers after their certification and approval.

Space breeding can generate mutations faster and more conveniently than ground-based experiments and can bring about some desirable traits that are otherwise hard to introduce. Compared with natural or conventionally bred types of plants, space-developed versions with positive mutations usually feature higher nutritional content, greater annual yields, shorter growth periods and better resistance to diseases and insect pests.

China conducted its first space breeding experiment in 1987, using a satellite to carry seeds into space. Since then, hundreds of kinds of seeds and seedlings have traveled with dozens of Chinese spaceships. Space breeding has helped to produce more than 200 new types of mutated plants in China that have been approved for large-scale cultivation, ranging from grains to vegetables and fruits. The Chang'e 5 robotic mission returned 1,731 grams of lunar rock and soil to Earth, marking a historic accomplishment 44 years after the last lunar substances were taken back.

8 . Have you ever noticed little specks (斑点) in the iris (the colored part) of your eyes? The specks, which occur in about 60% of the population, are clusters (组,族) of abnormal melanocytes (黑素细胞).Experts suspect that, like skin freckles, they may develop in response to sun exposure."We think that the pathway involved in iris freckles formation could be quite similar." Christoph Schwab, MD, wrote in an email to Health.

To investigate this theory, Dr.Schwab teamed up with other ophthalmologists (眼科医生) and dermatologists (皮肤病专家) to examine the skin and eyes of more than 600 people.Seventy-six percent of the participants possessed at least one eye freckle.They tended to be older than folks who had no eye freckles.And they were also more likely to report a high number                    of sunburns during their lifetime, and have sun-damaged skin and age spots.The researchers also noted that the participants were recruited（招募） from public swimming pools.They may have led outdoorsy lifestyles, with greater exposure to UV light than the average person.

While eye freckles themselves are usually not dangerous to health, they may serve as a warning sign for sun-related health problems, the researchers concluded."The presence of iris freckles also indicates sun damage to the skin, a risk factor for several different kinds of skin cancer.Within this context, there is certainly a need for further studies investigating the association between skin cancer and iris freckles, they wrote.

"The investigation of iris freckles in several eye diseases could lead to new knowledge regarding their pathogenesis (病原)," says Dr.Schwab.

For now, Dr.Schwab urges caution: If someone exhibits iris freckles, especially at a young age, I would reconsider current sun protection strategies."To keep your skin safe and your eyes freckle-free, remember to apply plenty of SPF even when it's cloudy, and wear shades or a hat to protect your eyes from the sun.

9 . Have you ever had the feeling that you can't think when there is too much noise around? Did you ever think a fish could experience that feeling too? A recent paper published in Science titled “Soundscape(声景)of the Anthropocene Oceans”, combined over 10,000 scientific papers, confirming that undersea life knows that exact same feeling, more often than not. Anthropogenic(人为的)ocean noise, also known as underwater noise pollution, has created a dramatic impact on marine life due to “human-caused” activity within and neighboring our oceans.

Disney Pixar's animated film Finding Nemo educated us about the ocean, and specifically within the ordinary world of a clown fish. A fact many may not know is that clown fish spend the first part of their lives as larvae(幼体), drifting with the current(洋流)of the ocean until they become strong enough to swim against it. Once they are powerful and strong, they head home in sheltered coral reefs. There is only one disadvantage-the fish can't physically see the reef, but they can hear it. The only problem is, if they can't hear it, will they ever make it home?

Our anthropogenic ocean noise, such as cargo ships, ship and boat propellers, surfing, deep sea mining. etc. are causing destruction of marine life. According to Time, sound is the sensory signal that travels the farthest through the ocean. Anthropogenic noise drowns out the natural soundscapes, putting marine life under immense stress. Altogether, this stress then affects their general health, disturbs their behavior, physiology. reproduction and, in extreme cases, causes death. Marine life can adapt to noise pollution, however, only if they can escape it. This only renders further complications(困难, 问题)of straying(使偏离)species from their traditional breeding regions or separating them from their families.

Now, what if we told you there is already a solution? Multiple remedies, ideas and designs are currently in the works or already exist to get rid of and change the damage of anthropogenic ocean noise. As Time explains, from wind-powered ships to noise-reducing propellers(螺旋桨)，floating wind turbines(风力发电机)and “bubble curtains” that muffle construction noise, the solutions are already available and in some cases, cost-effective(划算的). The authors of the paper hope it will catch the attention of policymakers, who historically speaking, have ignored the mater still to this day.

Of all the challenges ocean creatures are battling, luckily sound pollution is the easiest compromise humans can make. Once the noise has decreased, marine life will be able to better manage everything else it is up against.
