Eating on a plane used to be common practice. But in the age of COVID-19, many passengers are     1     less inclined to remove their masks to take a mid-flight bite ― or to even have a snack at the airport.

As a result, it’s more common to eat at home before embarking on a flight. Those with longer travel journeys may even eat a large meal to carry them through the day. Still, not all preflight eats are created     2    .

Tracy Lockwood Beckerman, a registered dietitian based in New York City, said it’s worth considering your overall health as you prep for travel, including what you eat and drink. “It’s important to eat foods that will keep your immune system strong, keep you hydrated and are easily digested before flying,” Beckerman said.

So, which foods are best     3     on a day when you’re traveling by plane?

“It’s super common for dehydration to set in when flying, thanks to the lack of humidity and dry air in the     4    ,” Beckerman said. “That’s why it’s not the smartest to have a meal high in sodium (钠) the day before or morning of your flight.” Beckerman also advised going easy on the salt shaker, opting for snacks without added salt to avoid dehydration-related headaches.

Alcohol consumption tends to cause dehydration and has a different effect on the body than if you were to have a drink at ground level due to the low pressure in the cabin and the low oxygen     5     in blood. Therefore you are more likely to get drunk faster and urinate frequently.

A cup of coffee can leave you dehydrated in an already dry environment and coffee also has a mild diuretic effect, which can lead to more frequent trips to the bathroom.

Beyond the dehydrating effects, caffeine can also keep you awake during a flight, which is often an opportunity to catch up on sleep. The need for more frequent bathroom visits can also     6     with your ability to doze during your travels.

If you have a sensitive stomach, you might want to     7     clear of foods that can mess with your digestion. That includes highly     8     snacks like candy and fast food, which often contain ingredients that could     9     your digestive system.

A balanced meal that satisfies your     10     with water and hydrating fruits contains moderate amounts of complex carbohydrates and lean protein, and is low in added sugars and sodium is ideal.

From roughly the 16th to 19th centuries, much of the Earth was caught by a persistent freezing cold. During this time, the Northern Hemisphere (半球) experienced long stretches of temperatures so cold that people witnessed crops     1     and rivers freezing — like the Scheldt River. Thousands of people walking and playing across the frozen River Thames; Soldiers on horseback seeing ships     2     in the ice; Natives using snowshoes to outsmart the English army…These were some of the images that define the Little Ice Age — a period of several centuries last millennium in which parts of the Northern Hemisphere struggled with a(n)     3     cold. But what caused the Little Ice Age, how long did it last, how did people     4     to the freezing cold — and what lessons can we learn as we enter our own period of climatic change?

The Little Ice Age was not a true ice age —     5    cooling was probably only in the order of 0.5 degrees Celsius, or 1 degree Fahrenheit — or was it consistently cold. Dagomar Degroot, associate professor of environmental history at Georgetown University has     6    to the era as a series of “little ice ages.”

Although some researchers argue it may have begun earlier, NASA defines the Little Ice Age as beginning around 1550 and     7     of three cold peaks-around 1650,1770 and 1850.

Scientists are still working out     8     what caused the Little Ice Age too. Theories     9     from decreased solar activity to increased volcanic eruptions, to the decline of populations in North America, which allowed forests to replace agricultural land, in the process removing about seven billion tons of carbon from the atmosphere. A 2022 study argued that the     10     trigger was actually a rise of extremely warm water flowing north from the tropics in the late 1300s,which pushed Arctic ice into the North Atlantic.

Whatever the cause, the consequences of the Little Ice Age have a lasting effect on history, although to what extent is still controversial.

Britain appears to be in a mental-health crisis. In the past decade no European country has seen a greater increase in the use of antidepressants(抗抑郁药); now only the Portuguese and Icelanders are popping more of the     1    . Around 4.5m Britons were in contact with mental-health services in 2021-22, a rise of almost l m in five years.

There are a few reasons why Britons might be unhappier than their     2    . One global poll found that teenagers in Britain were some of the loneliest in the world, with few supportive relationships and a low sense of purpose and meaning: all risk factors for poor mental health. Britain’s poorest households are also     3     off than their equivalents in France and Germany, for example, which makes them more vulnerable to conditions such as anxiety and depression. And Britain’s health system can seem more     4     than those in most other rich countries. In England alone, some 3.8 m are waiting for mental-health treatment.

Those factors might explain why more people are     5     to medication. Another reason is increased awareness. Campaigns around depression and anxiety have been particularly successful in Britain. That is     6     a good thing. A reduction in humiliation (蒙羞) has encouraged more people to seek help. Taking antidepressants – or using mental-health services — has become much more acceptable.

But there is a     7     to this, as The Economist recently reported. Surveys suggest that Britons are increasingly     8     common human emotions, such as stress and grief, as mental illnesses. “You’re going to lose any sense of what mental illness is if you start to     9     it to 30%, 50% of the population,” says Adrian Massey, author of a book called “Sick-Note Britain”.

For all the focus on anxiety and depression in campaigns, severe mental illnesses still receive too little attention. This is a problem: according to the GBD, Britain has the highest rates of severe mental illness in Europe. The causes of such conditions are unclear, but seem to involve a     10     interplay of genetic and environmental factors. Illegal drug misuse, for which Britain has among the highest rates in the region, also plays a role.

Dolphin Senses

New research involving trained dolphins seems to further prove that these animals can sense electricity. The     1     may allow them to better lock onto hidden fish hunted and direct the path.

The ability to sense electric fields is known as electroreception(电感受). All animals produce a weak electric field, but electroreception has almost     2     been found in water creatures. About a decade ago, scientists published research suggesting that some dolphins have passive electroreception. And in 2021, researchers in Germany released their own study finding that dolphins likely have it, too.

This new research is a follow-up to that latter study by the same team—one intended to better describe the     3     of electroreception in bottlenose dolphins. The researchers teamed up with scientists from the Nuremberg Zoo, which currently     4     six dolphins. They specifically worked with two bottlenose dolphins named Donna and Dolly. They first trained them to rest their jaws on a metal bar in the water, and then to respond to an electric field     5     them by swimming away within five seconds. They then gradually     6     the strength of this field to test the dolphins’ sensitivity.

The findings further prove that bottlenose dolphins can indeed sense electricity, but suggest that some dolphins are better at it than others. Donna, for instance, was a bit more     7     and able to respond correctly to a weaker field than Dolly.

The electroreception found in dolphins doesn’t     8     to be as strong as it is in the typical shark, but it’s probably still useful enough for them to find fish     9     underneath sand, stones or mud within a few centimeters away. Other studies have suggested that dolphins also possess a sense that acts as a sort of     10     GPS for them. So these dolphins’ electroreception might provide an explanation for that ability as well, Huttner said.

Several deep-sea fish have been mysteriously washed up on California’s beaches this year, leaving marine biologists     1    .

The latest Pacific football fish to be washed     2     in the state was spotted near Encinitas last Friday. A surfer found the strange fish dead on Swami’s Beach and alerted lifeguards, who then notified scientists. Scientist Ben Frable then collected the unusual animal for research and     3     purposes.

The fish is black, almost spherical in shape and has sharp teeth. It has a strange external body sticking out from its head with multiple branches, used to attract prey in the     4     blackness of the deep ocean.

The fish found on Swami’s Beach is a mature     5     measuring nearly 13 inches in length and weighing around 5.5 pounds.

Pacific football fish are very rarely seen considering that they are     6     found at depths of between 650 and 2,600 feet. Only 31 known fish have ever been collected     7    and it has never been seen in the wild, so scientists know very little about the species.

Despite the fact that the fish are rarely seen, three of them have been washed up on California’s beaches this year —including one that was spotted last month at Black’s Beach, north of San Diego. The three sightings this year     8     the total number of sightings on record in California, and it’s the     9     of the town among the experts working at the Los Angeles County Natural History Museum, which has four fish in its collection.

Despite the series of recent sightings, experts said, it’s hard to jump to any     10    about why this is happening.

What Is 2023’s Word of the Year, According to Dictionaries?

What word defined the past year for you? Find out if your answer matches the actual word of the year from four famous dictionaries.

Cambridge Dictionary’s     1     for 2023 is hallucinate. The common definition of hallucinate is “to see or hear things that are not really there because of illness or drugs.” In 2023, however, to hallucinate can mean something different, thanks to AI. According to Cambridge’s alternate definition of hallucinating, “when an artificial intelligence hallucinates, it produces false information.” Sure, using AI can be fun for creating dog selfies or could even help you     2     a job, but it’s likely to produce misleading or made-up facts — or “hallucinating.”

Those dictionary people are     3     all on the same page. Similar to Cambridge, Collins Dictionary’s word of the year is the broader term AI. ChatGPT was released in late 2022, with companies attempting to use it to cut costs, worrying employees that it would     4     their jobs. AI pioneers and creators began     5     concerns that AI could be “dangerous” and operated by “bad actors.” President Biden even issued an executive order on “safe, secure and     6     artificial intelligence.”

With Merriam-Webster’s word authentic, we have an AI trifecta (三连胜)! While its core meaning is the same — “not false or imitation” — it should     7     its popularity in 2023 to AI, with the rise in deepfake videos and the potential use of AI in entertainment. However, being authentic is also about being “true to one’s own personality, spirit or character.” Are the public figures you look up to being true to themselves? As people search for authenticity, Merriam-Webster notes, “    8    , with ‘authentic content creators’... authenticity has become a performance.”

Oxford slides in at the last minute with a totally different word of the year for 2023: rizz. This noun means “style, charm or attractiveness”. It’s believed to be a shortened     9     of the word charisma, a special magnetic charm or appeal. It also hints at a changing attitude in 2023. “It’s interesting to see a contrasting word like rizz come to the forefront, perhaps showing that this year more of us are opening ourselves after a few     10     years and finding confidence in who we are,” notes Casper Grathwohl, president of Oxford Languages.

College Rankings Are Something, but Not Everything

I am always confused when reading statements like “Princeton University is the number one college in the United States.” Are those who attend Princeton inherently brighter than their     1    ? Is Princeton able to produce more geniuses upon graduation?

High-ranking colleges in global education leagues attract greater talent in staff and students, and     2     better facilities, therefore generating more profits. In the United States, however, this virtuous cycle can turn vicious when financially-challenged parents end up spending their life savings on their children’s education, while     3     individuals can simply buy their way in. Besides, these rankings face criticism for potentially influencing colleges to make minor adjustments in     4     to improve their position on the table.

I didn’t care about college rankings for years until I recently saw something different. This past October, Shanghai Ranking Consultancy     5     the Global Ranking of Academic Subjects 2023, which assesses universities worldwide across 55 subjects in five disciplines. It is said to employ a more in-depth     6     to evaluate the performance of universities. And this makes it easier for prospective students to choose the best college for their specific subject. But how much weight should you give to these rankings?

In my opinion, college rankings can serve as a reference, offering a     7     into the reputation and strengths of institutions. However, they should not be the only determining factor for you. There are many aspects to a university education that can only be     8     when you are clear about your goals.

I once taught a three-month program to prepare university students for overseas exchange programs in England. But some of them displayed low     9    . It wasn’t merely due to a language barrier. These individuals seemed to lack communication skills, critical thinking and, more importantly, a     10     of purpose, which might help determine their future academic quality. After all, what lies in the heart of education is “U” .
