3 . Studies have shown that walking among trees makes us relaxed.
For the study, researchers worked with 296 children between the ages of 9 and 12. To measure how connected they were to nature, the kids were asked how much they enjoy activities like seeing wildflowers and wild animals, hearing sounds of nature and touching animals and plants.
So exposure to nature is related to active behaviors and happiness of children. What does that mean to adults? As we all know, children usually tend to follow adults, especially their parents’ behaviors.
Researchers say that children need role models who can guide them to nature with excitement and an attitude of a lifelong learner. Parents don’t have to be experts in environmental science or nature studies.

4 . Have you ever found that you were able to sleep better with an air conditioner or fan running or perhaps with the sound of rain falling outside? If so, then you’re already familiar with white noise.
White noise refers to a noise that has a mixture of all the audible (听得见的) frequencies that the human ear can detect. It is a combination of all the frequencies of sound played at once. It can cover the sounds of other noises because of its various frequencies, leading many people to experience its calming effects.
Researchers have studied the effect of white noise on humans for many years, finding evidence it can reduce crying in infants and improve work performance. Many studies have also examined how white noise may affect human sleep. They found that listening to white noise positively affects sleep. For example, people living in a high-noise area of New York City fell asleep faster and spent more of their time in bed asleep while listening to white noise. In another study, listening to white noise through headphones improved sleep quality for seriously ill patients in a loud hospital room.
However, a recent analysis of multiple studies looking at white noise’s effect on sleep has produced mixed results. The researchers are doubtful about the quality of existing evidence and conclude that further research is necessary in order to widely recommend white noise as a sleep aid. They also note that in some instances, white noise can perturb a person and may affect their hearing.
Despite that, researchers are still optimistic that the steady white noise might reduce a sleeper’s sensitivity to unpredictable noises from the environment, such as transportation sounds like cars and planes, which are considered a major contributor to poor sleep.

6 . It’s a sweet moment, as a chimp reaches up to kiss his mother’s face. The touching photo was taken by the famous conservationist and activist Jane Goodall in 1993 in Gombe National Park in northwest Tanzania where she has studied chimpanzees for more than six decades.
The image is part of Vital Impacts consisting of a group of 100 photographers. The women-led non-profit was founded by award-winning photographer Ami Vitale and visual journalist Eileen Mignoni. They are selling fine arts images, most of which focus on wildlife and nature, with earnings benefiting conservation organizations including Jane Goodall Institute’s Roots and Shoots program.
“Our purpose is to use photography to create awareness and understanding; to help us see that the survival of the planet is closely connected with our own survival. As photographers, we have a huge opportunity to inform and influence change, but pressing the shutter (快门) is just the start,” Vitale said.
“For an image to have significance, it needs to reach people. To this end, we are working to get the photographs of Vital Impacts photographers and our students into high-profile media and exhibitions around the world.”
The organization gives special attention to photographers who are committed to the planet. Funds will be used to support global conservation and environmental initiatives and the group will offer two $20,000 environmental storytelling awards.
Vital Impacts has raised more than $1.5 million from the sale of fine art prints since the organization was set up in late 2021. Some of its profits were donated to the organization Direct Relief, which shipped more than 1,400 tons of medical supplies worth $545 million to support 351 healthcare equipment in disaster zones. Other profits were able to provide fuel and vehicle assistance to support wildlife corridors (廊道), a monitoring program, and the restoration of the Snake River in the Pacific Northwest.

9 . A team of researchers at ETH Zurich has the perfect long-lasting solution to our fog problem. They have developed a very thin and gold-based transparent coating (涂层) that can convert sunlight into heat, which can be applied to glass and other surfaces to prevent them from fogging.
The special coating is developed using titanium oxide and gold particles. It selectively absorbs infrared radiations (红外线辐射) from the sunlight and creates a heating effect that is powerful enough to keep fog away from the surface of an object. The coating basically employs heat to stop fogging. The coating absorbs a large part of the infrared radiation, which causes it to heat up-by up to 8℃.
Previously, products like anti-fogging sprays (喷雾) create a very thin film of water on the surface to remove fog. The problem with such surfaces is pollution. Along with water, the sprays also attract dirt, dust, oil, and various other dirty substances, and just a little dirt on the surface makes it useless. However, the new coating repels (排斥) water. Furthermore, the coating is significantly thinner, which makes it more transparent as well as flexible. It is heated passively and requires, during daytime, no additional energy source.
Gold might be expensive, but the researchers stress that their coating requires so little that the material costs remain low. Their coating is produced with standardized and readily scalable methods, all cost-effectively. However, although this product can work at very low levels of solar radiation, it does rely on a certain amount of light.
The researchers will develop the coating further for other applications. In the process, they will examine whether other metals work just as well as gold. There is no need to fear. However, this would cause a car or a building to heat up more in the summer. The researchers have already filed a patent. Hopefully, this groundbreaking product will soon be available on the market.
