3 . There’s been lots of concern recently about the potential dangers of microwave popcorn (爆米花), but is this concern founded, or just overmuch fear-spreading? The answer is that many of the chemicals that caused worry in earlier decades have been removed from microwave popcorn, but some critics still are not satisfied.
“You may consider popcorn to be a low-calorie, high-fiber snack, but microwave popcorn isn’t a healthy choice,” explains nutrition expert Dan DeFigio. That’s because microwave popcorn bags were coated with perfluorinated chemicals (PFCs) to prevent oil substance from leaking out. One particular type of PFC, known as perfluorooctanoic acid (PFOA), has been linked to certain cancers, but the American Cancer Society says the evidence is unsure and more research is being done about this.
Nevertheless, in response to concerns about PFCs, the U.S. Food and Drug Administration (FDA) worked with popcorn makers back in 2011 to remove PFOA from their packaging. Three more PFCs were banned in the next five years. So today’s microwave popcorn doesn’t have these chemicals, but critics say that the alternatives could cause problems as the old ones, but less is known about them.
That’s not the only problem, however. The chemical that for decades lent buttery deliciousness to popcorn has also been connected in rare cases with major lung damage. Known as diacetyl (二乙酰), it’s long been a documented problem with workers in popcorn making facilities, but also can be risky for people who just eat the snack a lot. A 2007 study published in the journal Critical Reviews found that more than 80 percent of chemical release happened when the bag was opened post-popping. Although diacetyl has been removed from most products, some critics claim that the alternative to diacetyl is also harmful.
Most of the exposure to diacetyl came from inbreathing rather than eating popcorn. Therefore, experts recommend at least waiting for the bag to cool before you open it to reduce potentially harmful chemical exposure. Better yet, make your own fresh at home with an air popper. If you like to flavor it, add organic butter or some cheese.

4 . In recent studies we have been investigating mirror writing by typical 4- to 6-year-old children. The term is used because the characters — numbers and capital letters — are reversed (反向), yet are correct when looked at in a mirror.
Mirror writing entered the scientific literature in 1878. The explanations for the phenomenon were not only insufficient but also often wrong. One of them is — writing with the left hand. Throughout the 20th century, scientific journals have published mirror writing mostly produced by left-handed children. Even today, left-handedness is often the favorite explanation of teachers when children produce mirror writing.
The explanation we find for the phenomenon of mirror writing of characters works on two successive levels, the first cerebral and the second behavioral. The cerebral level shows that the brain removes orientation (left or right) when storing images, a process called symmetrisation or mirror generalization. This mirror-generalization process leads children aged 5 to know, from memory, the shape of the characters, but not their left/right orientation. Given the features of the process — horizontal mirror in the visual modality (视觉模式) — it is important to note that the initial learning of the form of the characters by the children is mainly visual, and that the children only produce horizontal mirror writing.
At the behavioral level, when children write the characters from memory, they must give them an orientation. In countries whose primary languages are written in Latin characters — written from left to right — children most often point them toward the right. This leads them to reverse mainly the left-oriented characters: J, Z, 1, 2, 3, 7, and 9. However, when spatial constraints cause them to write from right to left, the children instead reverse the right-oriented letters.
Since this explanation has nothing to do with the handedness of the children, it can be predicted that right-handed children will reverse characters almost often as left-handed children, and that – left-handed or right-handed – children will primarily reverse left-oriented characters in Western culture. This is because they strictly orient the characters in the direction of writing.

9 . Most people, if you quizzed them, probably wouldn’t know how much of all global trade is done by sea. It’s one of several reasons that the pollution and carbon emissions from shipping gain much less attention than those from road transport and other industries. It’s over the horizon, out of sight and out of mind.
Today, the international shipping industry is the main mode of transport for around 90 per cent of world trade. It’s powered almost entirely by fossil fuels. Studies show that alternative technologies and zero-emission fuels — including electrofuels such as hydrogen, ammonia and methanol — have the potential to significantly reduce the industry’s carbon footprint and thus require urgent implementation (实施). There’s just one catch: they don’t exist yet.
Even if the technology were available, the infrastructure (基础设施) for that technology or fuel is going to take time to develop. And an even bigger challenge is going to be whether that methanol or ammonia fuel is green, which touches on other industries such as renewable electricity. Do we even have enough renewable electricity in the world to be able to generate these fuels? It’s a complex supply chain that requires cooperation across the industry. It’s not something that one company can solve by itself.
According to Piotr Konopka, senior manager for energy and decarbonisation (碳减排) programs at DP World, there are some simple behavioral changes that can help cut down on fuel used in the meantime, from the regular maintenance and reduced idling of port equipment to the implementation of weather routing that helps ships avoid rougher, more fuel-intensive stretches of water. “Of course, efficiency is unlikely to ever reduce emissions by more than five or ten per cent, but it’s definitely a low-hanging fruit,” he says.
“This is the last moment for the IMO to act decisively to eliminate shipping emissions” says Delaine McCullough, shipping emissions policy manager at environmental NGO Ocean Conservancy. “We need countries to demand that the IMO set strong emission-reduction goals and take action at home if the IMO fails to do the right thing.”

10 . A common claim states that a sheet of paper cannot be folded in half more than seven times. But is this true?
In 2002, Britney Gallivan, then a junior in high school in Pomona, California, folded a single piece of paper in half 12 times. She currently holds the Guinness World Record for the most times to fold a sheet of paper in half.
The prompt that led Gallivan to accomplish this was an extra-credit challenge in math class to fold anything in half 12 times. Her teacher asked the students to fold something thicker: a piece of paper.
Gallivan said “it was very frustrating, as I had many unsuccessful attempts at trying to fold different papers in half. I began to question if folding paper in half more than eight times could be impossible.” However, Gallivan recalled. “I knew I needed to understand what was limiting the folding progression.”
The equations (方程式) that Gallivan came up with calculated how many times a sheet of paper could be folded. She found that in order to fold many times, a long thin sheet is needed — the more a sheet is folded, the thicker the resulting stack becomes, and once the stack becomes thicker than it is long, there is nothing left to fold. She ultimately set her record with a sheet of tissue paper she found online that was 4,000 feet (1,219 meters) — more than three-quarters of a mile, or over a kilometer long, Guinness World Records noted.
“Working on the problem took a tremendous amount of time and effort,” Gallivan said. “As frustrating as it was at times, I learned an immense amount from the experience, which has been valuable to me throughout my life in more capacities than one would expect.”
Since Gallivan set her record, others have made claims of folding a sheet of paper more than 12 times. Still, “I anticipate that my current record will be surpassed,” Gallivan said.
