Growing up, I never wore makeup and I was always more afraid of the mirror than anything else. I hadn't thought makeup was meant for me, a disabled woman, until I saw Ulta's new advertisement: a huge full-color photo of a model in a wheelchair.
The world of fashion and beauty is rarely related to disabilities, and even though Hollywood has made steps toward greater inclusion and clothing brand Aerie has featured women with disabilities in their advertisements, seeing disabilities in the mainstream is definitely unusual. The reason why these things make headlines is that they're so rare.
I learned from a very young age that because of my disability, I would never be connected with beauty or charm. I'd spent so long feeling separated from so many parts of society, but Ulta is sending a powerful message with a single photo：It's time to challenge conventional beauty standards because beauty comes in all forms.
We all want to feel included. When it comes to disabilities, it is so important, especially for children and teens with disabilities. I was well into my 30s when I rolled into a makeup store for the first time. I had no idea what I was doing and felt like entering a new world without a map；I felt like I was out of place, as if I was peeking at a club without being invited. Imagine how my experience would have been different if I had seen a model in a wheelchair, smiling, as if to say, "Welcome. Yes, you belong!"
That message of inclusion was loud and clear for Maren Anderson, a 4-year-old girl who has a rare genetic disease and just started using a wheelchair. The moment she spotted the advertisement was caught on camera by her mom Carolyn Anderson, and quickly spread last month on Facebook. "It's just really saying that she feels included, and she feels like she identifies with that, and belongs here just like everybody else. So, thank you, Ulta," said Carolyn Anderson.
Foreseeing a time when a patient's own cells may be harvested, multiplied, and fashioned into a replacement organ, researchers in Boston have successfully transplanted laboratory grown bladders (肾) into six dogs.
For a century, physicians have replaced diseased or damaged bladders by removing sections of a person's intestines (肠子) and shaping them into a substitute bladder. While the procedure offers some relief to patients, complications often develop because nature designs intestinal tissue for a purpose-absorbing nutrients-other than holding waste liquid of the body. "You start absorbing stuff that should be removed," says Anthony Atala of the Children's Hospital in Boston.
Other physicians have turned to human-made materials to create artificial bladders, but those efforts have also run into problems. Consequently, to build a better bladder, Atala and his colleagues decided to employ the organ's own cells.
To turn the cells into an organ, the researchers first form plastic which can break down naturally into bladder-shaped shell. They then coat its outside and inside with layers of cells needed.
To test this strategy, Atala's group obtained bladder tissue from dogs and grew it into organs. After removing the dogs' bladders, the investigators implanted (移植) the artificial ones coming from the dogs' own cells. Within a month, the organs began to perform like normal bladders.
Within three months, the plastic shells had broken down naturally, and the implanted organs were hard to distinguish from natural ones. Blood vessels (血管) quickly grew into them. Moreover, nerves seem to form proper connections with the new organs, allowing the dogs to regain normal control of their bladders. Some dogs have had the artificial bladders for nearly a year without any problems.
While the bladders of dogs closely resemble those of people, Atala warns that more testing of this transplant strategy must occur before artificial bladders are ready for the clinic.
Since the beginning of the summer in 2022, China has been sweltering under the worst heatwave in decades. A number of people in Zhejiang, Henan, Jiangsu and Sichuan provinces were diagnosed with thermoplegia (热射病), the most severe form of heatstroke, and some even died of this disease.
In a warming world, the hazards of heatwaves are increasing. According to a study, the number of deaths caused by heatwaves in China has increased rapidly since 1979, from 3, 679 persons per year in the 1980s to15, 500 persons per year in the 2010s.
"Over the past four decades, the main drivers of the large increase in heatwave-related deaths in China are the rapid increase in the frequency of heatwaves, followed by population growth, population aging, and rising baseline mortality(基线死亡率), "said Prof. Huang Cunrui, a researcher from Tsinghua University.
High temperatures would accelerate the loss in soil moisture (水分) and hurt the growth of corn, cotton, trees and fruits. What's more, each additional degree of warming will increase crop losses to insects by 10-25 percent, threatening food security for billions of people. China has witnessed a range of extreme weather events, including heavy rainfall, flooding, tornadoes and record heatwaves this year. Meteorological officials said the country had an average temperature of 21. 3 degrees Celsius in June, 0.9 degrees Celsius higher than the same period on average, and the highest record for the same period since 1961.
Experts say that while extreme summer heat is not entirely new, these sorts of occurrences could be something that becomes a standard part of life, requiring people to start learning how to cope with heatwaves that may continue for the rest of summer and well into the future.
Remember that even healthy, young athletes can be harmed by extreme heat, so every activity, indoors or outdoors, should be evaluated when extreme heat hits. There are some ways to stay safe during extreme heat events, such as drinking plenty of water, looking for shade or remaining in shade when outside, and avoiding cooking large meals that can add heat to your indoor environment.
Everyone knows the benefits of exercise: stronger muscles, more energy, weight management. But there is stronger evidence than ever before that movement can significantly improve your mental health. In fact, even if you were to exercise for the sake of your mind alone, it would be well worth doing.
If your primary aim is to improve your mood, the bar for what counts as exercise is far lower than it is for weight loss or fitness gains. You can see very large mental benefits with low-intensity exercise.
When any movement can bring benefits, the best activity is one you like to do — whether that's swimming, team sports or dancing. lf you are uncertain about exercising, or have had bad experiences in the past, you can sweeten the pill by combining it with socializing, time spent outdoors and music. Just moving for three minutes to your favorite song will make a difference.
Over time, the brain comes to associate exercise with that burst of happy-making chemicals, making it want to do it over and over again. It's important for the brain to learn that exercise is rewarding and make it a habit.
Is it possible to overdo it? The answer is yes. A minority will even develop clinical depression as a result of overtraining. But these bad effects are restricted to serious athletes. Swimming? 'Tai chi? Power lifting? Yes! It all works! "
A. Consistency is the key to mood lifting.
B. So the type of workout you do really matters.
C. A mood boost is often considered an added bonus.
D. You can seek out an activity that makes you feel good.
E. For the rest of us, any movement can only be beneficial.
F. What's more, moderate exercise can have huge mental benefits.
G. It's not like the longer or harder you exercise, the better you feel.
I'm standing in a class of wild 14-year-old girls as they throw paper and howl with laughter. They won't listen to me. I never wanted to1. I wanted to be a writer. But when I arrived in London, they were 2 of teachers.
My efforts at teaching were3. When the bell finally rang, I4to the staff room, red with anger. The other teachers weren't 5 . "That's 4B, the worst class in school."
But I couldn't give up. I 6 formal lessons. Instead, I brought topics for class discussion. One of the liveliest talks was about the arguments they had with their 7
They paid attention and were 8 to share about their family lives. Then I had them write about themselves. As time went on, their essays became a 9 between us. I 10their humor, toughness and eagerness, and I think they appreciated my interest in their lives.
The musical My Fair Lady was playing in the West End and I asked if they'd like to see the musical. They thought I was joking and did not take it 11 since no teacher had ever suggested taking them out. A few weeks later, 4B and I were 12 in theater. They loved the musical and the characters.
Near the end of the term, two most rebellious (叛逆的) girls with flowers were knocking on my door. I was 13 to know I had touched their hearts and made a difference to their lives, but they had also touched mine. I enjoyed teaching and getting along with14
When I returned to Australia several years later, I still 15 to be a writer. Teaching wasn't the end of my writing career; it was the beginning.

When a tornado(龙卷风) touched down in a small town nearby, many families were left completely ruined. Afterwards all the local newspapers carried many moving stories featuring some of the families who suffered the hardest.
One Sunday, a particular picture especially touched me. A young woman stood in front of an entirely shabby mobile home, a depressed expression on her face. A young boy, seven or eight years old, stood at her side, eyes downward. Clutching(抓紧) her skirt was a tiny girl who stared into the camera, eyes wide with confusion and fear.
The article that went with the picture gave the clothing sizes of each family member. With growing interest, I noticed that their sizes closely matched ours. This would be a good opportunity to teach my children to help those less fortunate than themselves. I stuck the picture of the young family on the wall in the living room, explaining their difficulty to my seven-year-old twins, Brad and Brett, and to three-year-old Meghan.
"These poor people now have nothing," I said. "We'll share what we have with them." I brought three large boxes down from the room upstairs and placed them on the living room floor. Meghan watched seriously, as the boys and I filled one of the boxes with canned foods and goods.
While I sorted through our clothes, I encouraged the boys to go through their toys and donate some of their less favourite things. Meghan watched quietly as the boys piled up old toys and games.
Meghan walked up with Lucy, her worn, much-loved rag doll hugged tightly to her chest. She came to the box that held the toys, pressed her round little face into Lucy's flat and painted face, gave her a final kiss and then laid her gently on the top of the other toys.
"Oh, honey," I said, "You don't have to give Lucy. You love her so much. "
Meghan nodded seriously, eyes filled with held-back tears, "Lucy makes me happy, Mommy. Maybe she'll make that little girl happy, too. "

The boys watched, open-mouthed, as their baby sister placed her favorite doll in the box.

Looking at my children for a long moment, I also removed my old jacket from the box of clothes.
