Less Snowy Winters
Winter might mean snowball fights in many places. But this might not be the case for much longer. While many people around the world are currently experiencing heavy snowfall, Earth is getting less snowy — a trend that isn’t temporary. That’s because the planet is heating up and winter is warming faster than any other season in America. The water falling to earth in winter is more commonly falling as raindrops than snow.
With water falling as rain instead of snow, and then freezing, some animals may struggle to feed on grass on frozen ground. Species with white coats could be at higher risk of being eaten as food, while polar bears may have fewer options to build their snowy habitations. Not every species can adapt or move to snowier climates, which may cause the extinction of some animals.
As air temperatures warm, trees release water into the atmosphere through a process called evapotranspiration, loss of water from the soil. When there hasn’t been much snow, the soil can’t replace lost moisture, and forests experience more heat stress, making severe wildfires more likely. “When a fire does spark, it runs away as fast as possible and burns as much area as it can,” says Andrew Schwartz, lead scientist at UC Berkeley’s Central Sierra Snow Laboratory.
For humans, less snowfall is “problematic because snow supplies so much of our water,” says Schwartz. About 1.9 billion people rely on snowpacks and big mass of ice for drinking water. Snow on the mountains acts like a natural lake used to store water. As it slowly melts into streams, snow supplies water through spring and summer, while rain flows immediately downstream and can be wasted. “It becomes more difficult to manage our water when we have these wild swings from year to year,” says Schwartz.

Why Are You Still Coughing?
Have you caught a cold recently — but can’t get rid of the cough? You’re not alone. The symptom can stick around for weeks after our bodies have cleared a virus. Michael Shiloh, a physician specializing in infectious disease research at UT Southwestern Medical Center, says coughing patients often report that they were sick as many as eight weeks prior to seeing him. He says, “
The United States saw a sharp rise in cases of influenza in late 2023 that’s dragged on into 2024. And though positive tests for the illness have leveled off or decreased countrywide over the past weeks, the number of people seeking healthcare for respiratory (呼吸的) diseases is still elevated across much of the U.S.
Coughing is an important reaction that protects the airway from dangers like water or bits of mis-swallowed food, says doctor and researcher Lorcan McGarvey of Queen’s University Belfast.
While it may seem obvious that coughing is meant to clear our throats, it’s also possible that viruses cause the reaction to help themselves spread.
“We don’t know,” says electrophysiologist Thomas Taylor-Clark of the University of South Florida. “But what we can say is that we do know some things, one being that viruses cause infection.”

How Long Is a Second?
The length of a second depends on how you’re measuring it. There are 24 hours in a day, 60 minutes in an hour, and 60 seconds in a minute — so surely a second is 1/86400, of a day, right? Well, it turns out that

8 . Recent years have seen a small increase in unemployment rates due to slowing of the economy. The fact that many college graduates are finding it difficult to land a job has sparked online discussions on the cost of education and the returns on it, with many agreeing with the notion that “education is useless”.
Stories like a person with a doctorate’s degree from Zhejiang University is delivering food, and overseas-returned graduates are selling hot-pot ingredients have caused many to question the value of education. Moreover, the fact that about 36,000 fewer candidates have applied to take the postgraduate exam in 2024, the first decline in numbers in years, has also fueled the “education is useless theory.
Is education truly worthless? This question has resurfaced due to several factors.
The wide spread of higher education has significantly increased the number of college graduates, reducing the value of college degrees. As the job market becomes over-crowded with graduates, the scarcity of high-level talents has become apparent, particularly in fields such as the humanities. For example, more than 900 institutions in China offer English major, making it the most common degree program, yet there’s a shortage of top talents who are proficient in English and have a good knowledge about the differences in Chinese and foreign approach to fields such as international relations and journalism.
The declining returns on the investment in education have given rise to the “education is useless” theory. Given the challenging job market, many believe college education does not guarantee any sort of employment, let alone a suitable job. And with various economic opportunities available, the notion that one can become financially successful even without formal education is becoming increasingly acceptable.
In light of these developments, combined efforts need to be made to change the situation. For instance, universities must take measures to integrate education, research and industry, while enhancing cooperation with enterprises through tailored talent training programs. Additionally, the authorities need to pay greater attention to vocational education, an important part of China’s educational system. Students, parents and society, on their part, should abandon their bias against vocational training, because it integrates education with career prospects throughout the learning process, offering targeted, technical and practical training which allows students to master their skills which can get them well-paying jobs in the future.
Developing a correct view of employment and career choice is key to abandoning the notion of “education being useless”. People, especially students, must understand the current employment landscape, their positioning, and strengths and weaknesses. While realizing that a college degree is no longer a ticket to employment, college students should leverage education resources to enrich their professional knowledge and competitiveness. And youths should approach vocational education with an open mind in order to make the most of what the job market has to offer.
Education is not synonymous with earning money, nor does a college degree guarantee financial success. The value of education is knowledge, which we need to make informed decisions not only in our professional life but also in our social and other fields of life.
