1 . A shocking news report has revealed that more than one in five species of maple trees faces extinction, warning that 75% of the threatened species are “geographically restricted” in their native regions.
The trees are experiencing a vast decline in habitat, due to urban development, wood harvesting and agricultural expansion. Time is running out for the world's biodiversity. Every recent survey of plants and animals in the wild points to this. This is happening nearly everywhere rarer maples exist. And because of climate change, the narrow habitats that support species at the edges of dry places and at the tops of mountains are quickly disappearing.
The trees can be found in subtropical and tropical regions, as far south as Indonesia. The only species found in the UK, the field maple is not under threat. Not only are the trees a popular attractive feature in parks and public spaces, but they are a key part of the natural ecosystem in woodlands, as well as being an important wood crop in several countries. Although the sugar maple in North America, which produces maple juice, is not endangered, two of the closest relatives to the species are endangered.
The report notes that conserving at-risk species in their natural habitat is the best conservation tactic. But collections in botanical gardens and seed banks-called "ex situ collections" can act as insurance policies against extinction. There are currently 14 species of maple, including four that are critically endangered, which are absent from these types of collections.
One species in Mexico, the Acer binzayedii, is in “desperate need of conservation"”despite only being discovered in 2017. “It is at risk from climate change in its cloud forest habitat and threatened by logging and forest fires while it is also absent from 'ex situ collections',” the report adds. The report recommends developing conservation plans, monitoring species currently not at risk to ensure populations are maintained, and adding those missing maple species to seed banks.

2 . A sleepover (过夜) program, which is designed to make kids believe that their favorite toys enjoy reading, can help encourage children to pick up more books, a new study suggests.
Toys sleepover programs are designed to get children interested in books. Children take their toys to a library for the night. At this point, workers and volunteers take photos of the toys which explore the library and read books. The next day, the children collect their toys and the photos of what the toys did during the night. They are given the books their toys chose to read.
It was found that before the sleepover the children did not spend time looking at the books in their play area at preschool. Immediately after the sleepover, the number of children who read to the toys was higher than the number who did not, but after three days the effect decreased gradually.
The researchers also tested a method for sustaining the effect. They reminded the children of the sleepover a month later, by hiding the toys and showing them the photos again the next day. This simple method brought an increase in the number of children reading to their toys.
The study proves for the first time that children who take part in sleepover programs read picture books to their toys more. “We wanted to know if there really was an effect, and if so, how long it lasts. Surprisingly, not only did the children show interest in the books, but they also began to read to their toys. This means that a new behavior pattern appeared that the children hadn’t had before. We did not expect anything like this,” said one of the researchers.
Reading is important for the development of children’s language skills and imagination. When parents read to their children, it is a passive way of reading for the child. However, when children read to their toys, it is a more active, self-directed way of reading, helping them develop into more active readers, researchers said.

3 . There are hundreds of types of birthday cake in the world. You are likely to enjoy one during at least one of your birthday parties. But have you ever stopped and wondered, “Why am I eating this? What makes this dessert fit to celebrate the day of my birth?”
It’s because you are as important and beloved as the gods.
The ancient Egyptians are thought to have “invented” the celebration of birthdays. They believed when pharaohs (法老) were crowned, they became gods, so their coronation (加冕) day was their “birth” as a god.
Ancient Greeks borrowed the tradition, but realized that a dessert would make the celebration more meaningful. So they baked moon-shaped cakes to offer up to the goddess of the moon. They decorated them with lighted candles to make the cakes shine like the moon. It is the reason why we light our birthday cakes on fire.
Modern birthday parties are said to get their roots from an 18th century German celebration. On the morning of a child’s birthday, he or she would receive a cake with lighted candles that added up to the kid’s age, plus one. This extra candle was called the “light of life,” representing the hope of another full year lived.
And then, torture — because no one could eat the cake until after dinner. The family replaced the candles as they burned out throughout the day. Finally, when the moment came, the birthday child would make a wish, try to blow out all the candles in one breath, and dig in.
Since the ingredients (原料) to make cakes were pretty expensive, this birthday custom didn’t become popular until the Industrial Revolution. More ingredients were available, which made them cheaper, and bakeries even started selling pre-baked cakes.
