2 . It’s a fascinating story of how nature is reclaiming and transforming the broken soil we leave behind. Wildlife filmmaker Dan O’Neill and zoologist Yussef Rafik are on a mission to uncover the wildlife secrets hidden inside some abandoned places.
Inchkeith IslandThis island off the Scottish coast had been an important strategic location for military defences for over 500 years by 1957. While its buildings might be empty and in bad condition, the wildlife has bloomed. Dan and Yussef watch young seal pups on the beach and spot seabirds and European cave spiders.
Dinorwi c QuarryDan and Yussef visit this former slate quarry(采石场) in Wales. Dinorwic closed its doors in 1969 and nature has slowly been reclaiming the land ever since. Dan and Yussef are searching for the fastest animal in the world, the peregrine falcon(游隼) and spot rare wild mountain goats.
Chatterley WhitfieldToday it looks more like a set from a film, but at its peak Chatterley Whitfield was a busy coalmine. Since it was closed in 1977, wildlife has taken hold. Dan and Yussef find plants including sunflowers that have sprung up in the most unlikely places. And hidden cameras capture footage of the rabbits and foxes wandering these empty buildings at night.
Nunhead CemeteryDan and Yussef explore one of the seven great graveyards in London, which was closed right after the Second World War and soon became neglected. Now hundreds of species live alongside the dead. Dan spots bright green ring-necked parakeets, the non-native bird that’s made London its home and the pair sample blackberries growing among the graves.

4 . Any schoolchild knows that a whale breathes through its blowhole. Fewer know that a blowhole is a nostril (鼻孔) slightly changed by evolution into a form more useful for a mammal that spends its life at sea. And only a dedicated expert would know that while toothed whales, such as sperm whales, have one hole, baleen (鲸须) whales, such as humpback and Rice whales, have two.
Even among the baleen whales, the placing of those nostrils differs. In some species they are close together. In others, they are much further apart. In a paper published in Biology Letters Conor Ryan, a marine biologist at the Scottish Association for Marine Science, suggests why that might be. Having two nostrils, he argues, helps whales smell in stereo (立体空间).
Many types of baleen whales eat tiny animals known as zooplankton (浮游动物), which they catch by filtering (过滤) them from seawater using the sheets of fibrous baleen that have replaced teeth in their mouths. But to eat something you first have to find it. Toothed whales do not hunt by scent. In fact, the olfactory bulb—the part of the brain that processes smell—is absent in such creatures. But baleen whales still have olfactory bulbs, which suggests smell remains important. And scent can indeed give zooplankton away. Zooplankton like to eat other tiny creatures called phytoplankton (浮游植物). When these are under attack, they release a special gas called dimethyl sulphide, which in turn attracts baleen whales.
Most animals have stereoscopic senses. Having two eyes, for instance, allows an animal to compare the images from each in order to perceive depth. Having two ears lets them locate the direction from which a sound is coming. Dr Ryan theorized that paired blowholes might bring baleen whales the same sorts of benefits.
The farther apart the sensory organs are, the more information can be extracted by the animal that bears them. The researchers used drones to photograph the nostrils of 143 whales belonging to 14 different species. Sure enough, baleen whales that often eat zooplankton, such as the North Atlantic right whale, have nostrils that are farther apart than do those, such as humpback whales, that eat zooplankton occasionally. Besides allowing them to breathe, it seems that some whales use their blowholes to determine in which direction dinner lies.

7 . People depend on insects to pollinate the plants that make many of the fruits, nuts and vegetables we eat. Past studies had shown urban air pollution might veil the smells insects use to find flowers. Computer models predicted this would cause problems for insects, seeking flowers for a meal. But scientists weren’t sure that would happen in real life.
James Ryalls, a biologist, and his team decided to find out if it would. Working in a field, his group crafted a system made up of large rings. Each area was open, so nearby insects could fly into it. The researchers pumped pollutant gases into these rings. Then during each field season, the scientists recorded how many times pollinators visited the flowers in each ring.
“The results were much more severe than we thought,” Ryalls says. Adding pollution “caused up to 90 percent fewer insects to be able to find the flowers that they need for food,” he says. This was in comparison to the pollutant-free rings. In some cases, only some 30 percent of the pollinating insects even entered the circles with polluted gases.
Counting insects proved easier than getting the pollution into the rings, notes Ryalls. He spent much of his time working on parts of the system that needed fixing. Along the way, gas spills occurred. “By the end of each summer experiment I smelt like a petrol station,” he says. One effect: “Insects now avoid me.”
Later, they counted seed pods on the plants. Overall, only around seven in every 10 flowers had been pollinated. That means there were far fewer seeds in polluted circles. If these were fruit or vegetable plants, there would have been far less food produced.
This study focused on insects finding flowers. But insects also use smells for communication and attracting mates. If air pollution covers those smells too, these tiny animals might face more threats to their survival.

8 . Seven out of the eight planets in our solar system were named after Greek or Roman Gods. You’re living on the only exception to that rule.
The word “earth” has roots in the Old English term “eorþe”. Eorþe had multiple meanings like “soil”, “dirt”, “ground”, “dry land” and “country”. Yet the story didn’t begin there. Old English is the earliest known stage of what became our modern English tongue. Used until about 1150 C.E., it evolved from a parent language that scholars call “Proto-Germanic”. The German that’s spoken today is part of the same linguistic family. “Earth” and “eorþe” are therefore related to the modern German word “Erde”. Not only is this the German language’s name fox our home planet, but it can also be used to refer to dirt and soil.
Our dear Each has relatives in some other languages, too, For example, there’s the Old Saxon “ertha”, the Old Frisian “erthre” and the Dutch word “aarde”. All these likely originate from a Proto-Germanic term that was never recorded. Nevertheless, linguists have been able to go back and reconstruct this mystery word. Spelled “ertho” in scholarly texts, it’s always marked by an asterisk (星号). This asterisk acknowledges the lack of written confirmation that the word was really used.
Nobody knows when people started using words like “Earth” or “Erde” to refer to the planet as a whole and not just the ground they walked on. Back in 1783, German astronomer Johann Elert Bode named the seventh planet from our sun “Uranus” (after a Greek god). And though Pluto is no longer considered a planet, we know that 11-year-old Venetia Burney named it in 1930. But if a single person gave planet Earth its English name, his or her identity has been lost to the sands of time.
Still, it’s clear that while Mercury, Venus, Mars, Jupiter, Saturn, Uranus and Neptune all started out as the proper names of ancient gods, “Earth” did not. That’s why our planet is sometimes called “the earth” with a lowercase (小写字母) “e”.

9 . Dogs need regular exercise to stay healthy and to stop them from getting bored. But the amount of time dogs need outdoors varies based on their age, size and breed.
Based on their age
While puppies are often bundles of energy, it is important not to over-exercise young dogs. A good rule of thumb for puppies is that they should enjoy five minutes of a movement twice a day per month of their age; so, for example, if your puppy is 12 weeks old, keep walks or play sessions to around 15 minutes each.
Elderly dogs may struggle to take long walks, but should still be given the opportunity to go outside and move around at their own pace at least twice daily.
Based on their size
All dogs should be let outside for exercise twice a day, but how intense that exercise should be depends, partly, on the size of the dog. Larger breeds need more space to wander around so, in addition to regular play in the house or garden.
Smaller dogs often require less space of a workout, so letting them out for a runaround, in addition to their daily walk, can be an appropriate form of exercise.
Based on their breed
Some breeds, such as border collies, springer spaniels, German shepherds and Siberian huskies, have been bred as “working dogs”, so are suited to covering long distances. Dogs such as labradors and poodles have bundles of energy, so they are also great companions for a long walk.
Brachycephalic breeds, such as pugs or bulldogs, are more likely to struggle with intense exercise. For these breeds, two shorter walks each day may be the best option; make sure to incorporate some rest breaks, and plenty of drinking opportunities, too.
