1 . 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.

7 . By the end of the century, if not sooner, the world’s oceans will be bluer and greener thanks to a warming climate, according to a new study.
At the heart of the phenomenon lie tiny marine microorganisms(海洋微生物) called phytoplankton. Because of the way light reflects off the organisms, these phytoplankton create colourful patterns at the ocean surface. Ocean colour varies from green to blue, depending on the type and concentration of phytoplankton. Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the ocean’s appearance.
Phytoplankton live at the ocean surface, where they pull carbon dioxide(二氧化碳) into the ocean while giving off oxygen. When these organisms die, they bury carbon in the deep ocean, an important process that helps to regulate the global climate. But phytoplankton are vulnerable to the ocean’s warming trend. Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunlight and carbon dioxide to grow, but also nutrients.
Stephanie Dutkiewicz, a scientist in MIT’s Center for Global Change Science, built a climate model that projects changes to the oceans throughout the century. In a world that warms up by 3℃, it found that multiple changes to the colour of the oceans would occur. The model projects that currently blue areas with little phytoplankton could become even bluer. But in some waters, such as those of the Arctic, a warming will make conditions riper for phytoplankton, and these areas will turn greener. “Not only are the quantities of phytoplankton in the ocean changing. ” she said, “but the type of phytoplankton is changing.”
And why does that matter? Phytoplankton are the base of the food web. If certain kinds begin to disappear from the ocean, Dutkiewicz said, “it will change the type of fish that will be able to survive.” Those kinds of changes could affect the food chain.
Whatever colour changes the ocean experiences in the coming decades will probably be too gradual and unnoticeable, but they could mean significant changes. “It’ll be a while before we can statistically show that the changes are happening because of climate change,” Dutkiewicz said, “but the change in the colour of the ocean will be one of the early warning signals that we really have changed our planet.”

8 . An extremely enthusiastic truth seeker who runs the YouTube channel Bright Insight claims（声称）to have found the mysterious city of Atlantis and insists that its true location has been hiding in plain sight for thousands of years.
In a video, YouTube blogger Jimmy Bright argues that the Richat Structure, a geologic dome（穹状物）in northwest Sahara also referred to as the Eye of the Sahara, is the most likely location of Atlantis.
He mentioned measurements from the famous Dialogues of Plato, which gave birth to the mystery. The Greek philosopher（哲学家）claimed that Atlantis was a long-gone kingdom, which stretched into Europe as far as Italy and into Africa as far as Egypt thousands of years ago. The giant island was said to be wiped off the face of the planet by a natural disaster“in a single day and night of misfortune”.
At first sight, this has nothing to do with the land-based Richat Structure, but Jimmy claims that the so-called Younger Dryas theory could be a possible explanation. According to it, a massive change in global temperatures caused unexpected climate change and sea level to rise.
In what can be viewed as another proof to the Sahara theory, the diameter（直径）of the Richat Structure’s outer circle is 23.5 km according to Google Map’s measurements, which matches those mentioned by Plato — 127 stadia, which is roughly 23.5 km in today’s terms.
Another thing that helps solve the mystery is a theory that the Eye of the Sahara closely matches the description from Plato’s dialogues. The ancient philosopher wrote that the main city of Atlantis consisted of circles of water and land, which, Jimmy said, looks very similar to the circular form of the Richat Structure.
Although the majority of researchers believe that Plato’s story was nothing but a moral story used to describe a failed idea of seeking power and searching for fortune, it has raised quite a few theories, Since the Middle Ages, explorers have been pointing fingers at different places around the world, including the Atlantic Ocean and the Mediterranean Sea, with the most amazing theories linking the location of Atlantis to the Antarctic and the North Sea.
