At this very moment around the world, athletes are stepping almost naked into freezing cold rooms. Why on earth are they doing this? Because it’s supposed to help them feel better.
The treatment is called whole-body cryotherapy (冷冻疗法). Basketball star LeBron James, soccer great Cristiano Ronaldo, and boxing champion Floyd Mayweather Jr. have all tried it. The therapy works like this. You take off everything but your underwear. Then you put on warm socks and gloves and step into a small room that looks sort of like a shower, except your head sticking 16% out the top. Once you’re locked in, air cooled to below -200°F (-129°C) fills the room. That’s way colder than Antarctica (南极洲). You stay in for two to three minutes.
Supporters believe the extremely cold air helps muscles recover faster and reduces other body pain. After his first cryotherapy sessions, Phil Mackenzie, a professional rugby player, felt noticeably better. He told Scientific American, “I felt refreshed right away. My sleep was better.” Soon, he was using it four times a week. Those who promote cryotherapy make all sorts of wild claims about its benefits. Supposedly, that extremely cold air can increase focus, improve skin tone, make you happier, burn calories, slow aging, and much more.
Is there any evidence to back up these incredible claims? Nope. Several small scientific studies have looked at whether the therapy can improve muscle recovery after exercise, with encouraging results. But there just isn’t enough evidence to show that the therapy works. The benefits some people experience may just be the placebo effect. That’s when a patient’s expectation that a treatment will work leads to an improvement.
The US Food & Drug Administration has actually issued a warning about whole-body cryotherapy. It cautions that the liquid nitrogen (氮) used to cool the room may make it difficult to breathe. Frost bite is another potential risk, which is why participants wear gloves and socks.
What do you think? Is it a chance for a better athletic performance worth the risk?

【推荐1】The Supreme Court’s decision on physician-assisted suicide carry important implications for how medicine seeks to relieve dying patients of pain and suffering.
Although it ruled that there is no constitutional right to physician-assisted suicide, the Court in effect supported the medical principle of “double effect”, a centuries-old moral principle holding that an action having two effects — a good one that is intended and a harmful one that is foreseen — is permissible if the actor intends only the good effect.
Doctors have used that principle in recent years to justify using high doses of morphine to control terminally ill patients’ pain, even though increasing dosages will eventually kill the patient.
Nancy Dubler, director of Montefiore Medical Center, contends that the principle will shield doctors who “until now have very, very strongly insisted that they could not give patients sufficient mediation to control their pain if that might hasten death.”
George Annas, chair of the health law department at Boston University, maintains that, as long as a doctor prescribes a drug for a legitimate medical purpose, the doctor has done nothing illegal even if the patient uses the drug to hasten death. “It’s like surgery,” he says. “We don’t call those deaths homicides because the doctors didn’t intend to kill their patients, although they risked their death. If you’re a physician, you can risk your patient’s suicide as long as you don’t intend their suicide.”
On another level, many in the medical community acknowledge that the assisted-suicide debate has been fueled in part by the despair of patients for whom modern medicine has prolonged the physical agony of dying.
Just three weeks before the Court’s ruling on physician-assisted suicide, the National Academy of Science (NAS) released a two-volume report, “Approaching Death: Improving Care at the End of Life”. It identifies the under-treatment of pain and the aggressive use of “ineffectual and forced medical procedures that may prolong and even dishonor the period of dying” as the twin problems of end-of-life care.
The profession is taking steps to require young doctors to train in hospices, to test knowledge of aggressive pain management therapies, and to develop new standards for assessing and treating pain at the end of life.
Annas says lawyers can play a key role in insisting that these well-meaning medical initiatives translate into better care, “Large numbers of physicians seem unconcerned with the pain their patients are needlessly and predictably suffering,” to the extent that it constitutes “systematic patient abuse”. He says medical licensing boards “must make it clear that painful deaths are presumptively ones that are incompetently managed and should result in license suspension”.

【推荐2】You’ve probably heard the saying, “Laughter is the best medicine.” Comedy on Referral has taken that idea and run with it, using standup comedy to help treat people struggling with depression and anxiety in partnership with the NHS.
The idea stemmed from comedian Angie Belcher’s experiences of teaching comedy at Bristol University. She found that students often told her how much stronger and more resilient (恢复力强的) they were thanks to standup comedy.
Inspired, she teamed up with the NHS in Bristol to create a six-week comedy course for patients struggling with depression in January 2022. Following the success of this initial course, Comedy on Referral won NHS funding to help men at risk of killing themselves in London.
Belcher will work alongside psychologists and men who have experienced self-killing events to use comedy as a form of therapy (疗法).
Talking to The Bristol Post, Belcher said, “Past depressions are perfect for comedy. Comedy doesn’t come from the happy, perfect moments of your life, but from our everyday struggles and major life events. People who’ve been through big life experiences such as the death of a close relation and ill health often can’t wait to tell me their story, mostly because there’s always something strangely funny about the situation.”
Research has shown that laughter has positive psychological effects, such as decreasing levels of cortisol (the stress hormone) and increasing endorphins (chemicals making you feel relaxed).
It can even have physiological benefits, although less research has been done in this area. Current research has linked laughter and humour with increased levels of pain tolerance as well as short-term cardiovascular (心血管的) benefits. More research is needed to prove these findings.
Nonetheless, the mental health benefits of regular laughter are widely accepted, and using comedy to treat mental health struggles could be a real breakthrough in the treatment of mental health.

【推荐3】A new medicine developed in China has been recently introduced, which is expected to significantly enhance the prevention and control of malaria in Africa. Compared with the previous medicines, this latest medicine is not only more efficient but also easier to administer. Its introduction is anticipated to result in a sharp decline in the number of deaths caused by malaria.
In case studies conducted in Kenya, second-generation artesunate(青蒿琥酯) for injection, developed by Chinese medicine company Fosun Pharma, has proved highly effective in treating severe malaria in children, Kenyan health experts said.
In addition, the new drug—produced under the brand name Argesun—can be easier and faster to prepare, and safer to inject, than its previous generation, which was produced under the name Artesun, and which was widely used in dozens of countries for more than10 years.
“We think that this is a very good development. It is really going to cut our rate of deaths and also the complications caused by malaria,” Walter Otieno said, a Kenyan Medical researcher.
Argesun was pre-qualified by the World Health Organization in June and has been registered in 18 African countries, according to Fosun Pharma.
Both Artesun and Argesun are innovative antimalarial drugs based on artemisinin (青蒿素), which was discovered by Nobel Prize winner Tu Youyou in the 1970s,and which has made significant contributions to malaria control and prevention in the world during the past two decades.
Wu Yifang, chairman of Fosun Pharma, said the company recognized the strategic value of antimalarial drugs based on artemisinin and restructured its sub company Guilin Pharmaceutical in 2004 to start introducing the drugs to the international market. Its first antimalarial drug entered Africa in 2007,and the company launched a training program for front-line medical workers in Africa in 2014.
“To win the battle against malaria, we have to get rid of it worldwide,” Wu said, adding that the company is pushing to transform its antimalarial drugs from “made in China and used in Africa” to “made in Africa and used in Africa”, in order to increase the accessibility and affordability of the drugs there.

【推荐1】Successfully making your morning to-do list could start with the first thing you put it in your mouth.
If you’re feeling like zombie (僵尸) in the morning, an unbalanced breakfast made primarily of simple sugars could be to blame, said Nancy Z. Farrell Allen, a registered nutritionist and spokesperson for the Academy of utrition and Dietetics.
“Carbohydrates — whether from fruits and vegetables or from sweets and cookies-break down to sugar in the body,” said McKel Kooienga, the creator of the Mindful Nutrition Method, via email. “Think of sugar as energy in the body.’
After we eat carbs, the pancreas (胰腺) produces the insulin (胰岛素) hormone to clear the sugar from the bloodstream, Kooienga explained. The type, timing and amount of carbs eaten determines how much sugar is introduced to the bloodstream at one time Simpler or processed carbs — such as muffins or maple syrup — introduce sugar to the blood at faster rate if not eaten with other nutrients like protein and fat, she said, resulting in short-term energy that causes.
Instead, think about delicious eggs, beans and cheese for protein, complex carbs and healthy fats. Or raspberries, oats and coconut for the same benefits.
“A balanced breakfast sets the pace and the tone for the day. It provides food that feeds both our brain and our body so that we can be mentally intact and productive out of the starting gate,” Allen said.
Having low blood sugar levels from regularly not eating breakfast can cause people to constantly reach for sugary and processed foods, which might “lead you down a path with food that can impact your mental health as well,” Kooienga said. That can lead to higher risk of turning to disordered eating behaviors, she added.
The concept of balance, Kooienga said, includes a combination of complex, fiber-rich sources of carbs, protein and healthy fats that would release sugar to the blood at a slower rate, supporting longer-lasting energy.
“There are so many wonderful options at breakfast time that provide the opportunity to explore cultural, delicious, healthy and mindful eating,” Farrell Allen said.

【推荐2】Food waste is both a problem for the industry and public health. Mori is considered as an “anti-waste company” and its mission is to make healthy food more accessible by keeping it fresher and longer. It is pioneering a natural, extremely-thin water-based coating that is applied to food to slow the exchange of gases that cause the food to go bad. About the thickness of two red blood cells, the coating is tasteless and unseeable, giving food a longer shelf life. The coating also enables less or alternative packaging.
Professors Fiorenzo Omenetto and Benedetto Marelli were investigating the power of silk to stabilize drugs when Marelli had the idea to stabilize something significantly larger: a strawberry. He coated the fruit with a silk solution and waited. Days later the strawberry still looked fresh—the coating worked.
When one compares a bunch of uncoated cabbage with those coated by the startup, the differences are striking. The uncoated cabbage is brown, dry, and uneatable. The coated foods look fresh and untouched.
What appears to be magic is thanks to the power of silk. Not silk threads like those used in the textile (纺织) industry, but a water-based solution made with silk molecules (分子). The startup’s core technology makes silk unseeable, but maintains its key molecular properties. Being a solution, the patent coating can be applied quickly and easily to any shape or size.
The technology Mori has developed works. But to make any progress in the global food waste problem, it must be able to come out in a massive way. Thankfully, silk is plentiful. The startup can use any grade of the natural material, including those rejected by the textile industry. As Marelli notes, “We could coat every apple in the U. S. today for only a small amount of the silk used in textile industry.” That’s a lot of apples.

【推荐3】Look up in the sky. See that French poodle? Before your eyes it morphs into an elephant. A few seconds later, it becomes the profile of Taylor Swift floating by. Cloud-watching has captured our imaginations since we were children. Many people even have found the International Cloud Appreciation Society.
In 2003 Gavin Pretor-Pinney was living in Rome while on holiday. After seven months glancing into the heavens at the mostly clear blue Roman skies, he discovered he missed the constantly changing cloud formations that were an everyday event in his native United Kingdom. He returned home and was engrossed in learning about clouds. The subject dominated his conversation for a year. Then a friend invited him to speak about clouds at a small literary festival. Pretor-Pinney titled his presentation "The Inaugural Lecture of the Cloud Appreciation Society." Afterward, he had to inform audience members who wanted to join the society that it did not exist. A few months later he launched a website, and the society was born. Five years ago it became his full-time occupation.
Today, the Cloud Appreciation Society enjoys a membership of more than 50,000 people scattered in 120 countries, all united through their appreciation of celestial mist. It is divided into local groups that include a chapter in St. Louis, and another in central Missouri. Illinois cloud spotter groups are near Chicago.
Pretor-Pinney thinks of the society as reconnecting people with their early relationship to the sky as children finding images in the clouds. "Clouds are for dreams, and a deep thinking of them benefits the soul. If you consider the shapes you see in clouds, it will save you money on psychoanalysis bills," Pretor-Pinney jokes.
In a positive Ted Talk about the Cloud Appreciation Society accessible on the Internet, Pretor-Pinney points out that clouds are common to everyone no matter where they are in the world. They are the most egalitarian (平等主义者) of nature's displays, because people all have a fantastic view of the sky.
