1 . Plants and exposure to greenery have been found to have multiple mental health benefits, such as lowering stress, decreasing feelings of depression, increasing sociability, restoring focus, improving cognitive performance, improving mood, and increasing self-esteem.
Gardening and care for plants can help to turn people away from negative thoughts or emotions. So with all that, what do these experts recommend as the best plant?
Snake plant. It’s very easy to care for, thrives in spaces with low sunlight, has visual appeal, and cleans the air, and they are drought resistant if you forget to water them.
Spider plants. Spider plants, with plenty of light-green leaves, are another low-maintenance selection.When a spider plant thrives, it will grow new offshoots that can be clipped and potted as a new plant.
Aloe Vera. Drought-resistant and easy to grow. Aloe Vera is low-maintenance, you can just water it monthly, and it helps clean the airspace and is helpful for burns, cuts, and scrapes to help injuries heal faster or soothe pain.
Lavender is well-known for its relaxing scent, and it has a calming effect, aids in reducing stress, promotes sleep.This means it’s great both in the garden, or clipped and dried in a bowl inside your space .
Basil is a summertime herb that loves the sun. Not only is it delicious in meals, but eating basil has health benefits, too. It has properties which help to relieve stress and anxiety.
Lemon balm. This fragrant green herb is part of the mint family and is simple to cultivate. Known for its calming properties, it has a light lemony scent that can be wonderfully intensified by rubbing the leaves between your fingers. It has been used to improve sleep, reduce stress and anxiety, improve appetite, and help with indigestion.

2 . From Latin America to Sichuan province, chili peppers and their famous burning taste have become a worldwide sensation (热门) .But how could something that burns so hot possibly be any good for people?
In a study by researchers at Marshall University in the Us, scientists made the first complete description of capsaicin (辣椒素)—a chemical found in spicy chilies—and its anti-cancer properties. Although capsaicin is not normally a good medicine due to some negative properties such as its spicy flavor, the study found that there are ways to bring out its anti-cancer benefits while overcoming these negatives.
In nature, capsaicin evolved as a defense mechanism in plants to drive away unwanted animals while attracting those that could spread the seeds, such as birds which cannot taste or feel the spice. From a scientific point of view, capsaicin works by triggering a pain receptor called TRPV1, causing the body to react as if it had actually touched something hot and dangerous. Yet, this natural repellent (驱虫剂) for most animals has instead become a favorite food for many people, often called “chiliheads”.
So, what is it that attracts humans to capsaicin, chili peppers and spicy food in general? Besides its many health benefits — such as pain relief, weight loss, and body heat regulation—people love eating chili peppers precisely because it hits the pain receptors in just the right way.
As Scientific American noted: “People seem to enjoy — and actively seek out—many other sensations ... the sensation of falling provided by roller coasters or skydiving, the feelings of fear and anxiety while watching horror movies, the physical pain experienced upon jumping into icy water, or even the feelings of sadness that come while watching a tearjerker.”
So, the next time you bite into a hot chili pepper, remember: its not just healthy, but fun too!

3 . With no special equipment, no fences and no watering, two abandoned agricultural fields in the UK have been rewilded (重新野化), in large part due to the efforts of jays, which actually “engineered” these new woodlands. Researchers now hope that rewilding projects can take a more natural and hands-off approach and that jays can shed some of their bad reputations.
The two fields, which researchers have called the New Wilderness and the Old Wilderness, had been abandoned in 1996 and 1961 respectively. The former was a bare field, while the latter was grassland—both lay next to ancient woodlands. Researchers had suspected that the fields would gradually return to wilderness, but it was impressive to see just how quickly this happened, and how much of it was owed to birds.
Using aerial data, the researchers monitored the two sites. After just 24 years, the New Wilderness had grown into a young, healthy wood with 132 live trees per hectare, over half of which (57%) were oaks. Meanwhile, the Old Wilderness resembled a mature woodland after 39 years, with 390 trees per hectare.
“This native woodland restoration was approaching the structure (but not the species composition) of long-established woodlands within six decades,” the researchers explained in the study.
Part of this reforestation was done by the wind, and researchers suspect that previous ground disturbance may have aided the woodland establishment—which is good news, as it would suggest that agricultural areas may be reforested faster than anticipated. However, animals—Eurasian jays, thrushes, wood mice, and squirrels—also played an important role in helping the forests take shape. This handful of species provided much of the natural regeneration needed for the forest to develop. Jays, in particular, seem to have done a lot of heavy lifting.

4 . Our world is full of sounds. Sound is so essential to life and survival that it made Tel Aviv University researcher Lilach Hadany ask: What if it wasn't just animals that could sense sound—what if plants could, too?
“Sounds are a natural resource-one that plants would be wasting if they didn’t take advantage of it as animals do,”said Hadany. If plants had a way of hearing and responding to sound, she figured, it could help them survive and reproduce.
Hadany's team started their study by investigating flowers. Evening primrose（夜来香）, which grows wild on the beaches and in parks around Tel Aviv, emerged as a good candidate, since it has a long bloom time and produces measurable quantities of nectar（花蜜）.
To test the primroses in the lab, Hadany's team exposed plants to five sound treatments: silence, recordings of a honeybee from four inches away, and computer generated sounds in low, intermediate（中等的）, and high frequencies. Plants given the silent treatment had no significant increase in nectar sugar concentration. The same went for plants exposed to high-frequency（158 to 160 kilohertz）and intermediate-frequency（34 to 35 kilohertz）sounds.
But for plants exposed to playbacks of bee sounds（0.2 to 0.5 kilohertz）and similarly low-frequency sounds（0.05 to 1 kilohertz）, the final analysis revealed an unmistakable response. Within three minutes of exposure to these recordings, nectar sugar concentration in the plants increased by 20 percent.
A sweeter treat for pollinators（传粉者）, their theory goes, may draw in more insects, potentially increasing the chances of successful cross-pollination. Indeed, in field observations, researchers found that pollinators were more than nine times more common around plants another pollinator had visited within the previous six minutes.
“We were quite surprised when we found out that it actually worked.” said Hadany.“But after repeating it in other situations, in different seasons, and with plants grown both indoors and outdoors, we feel very confident in the result.”
