At just 14 years old, Heman Bekele became the Nicole of the 2023 3M Young Scientist Challenge, standing out among nine other finalists with his creative invention known as the Skin Cancer Treating Soap (肥皂). An recognition of his exceptional achievement, this ninth-grad teenager is set to receive a cash award of $25,000.
Bekele’s revolutionary concept, presented through a brief two-minute video, centers on the development of a soap that is not only affordable, priced at less than $10 per bar, but also has the potential to reactivate (重新激活) dendritic cells — the body’s natural defenders of the skin — to fight against skin cancer.
In Bekele’s own words, “Curing cancer, one bar of soap at a time.” is passion for biology and technology was the driving force behind this ingenious creation, and the 3M Young Scientist Challenge provided him with the perfect platform to showcase his visionary ideas.
Reflecting on his inspiration, Bekele shared that his childhood in Ethiopia played a significant role in shaping his creative thinking. Having witnessed people work tirelessly under the burning sun, he couldn’t help but wonder how many were aware of the risks associated with prolonged sun exposure.
“I wanted to make my idea not only scientifically exceptional but also accessible to a broad audience,” Bekele expressed during an interview with The Washington Post. To aid him in realizing his big plans, he received invaluable guidance from Deborah Isabelle, a product engineering specialist at 3M,who connected him with other scientists. Eventually, the path forward for Bekele’s creation includes obtaining FDA approval.
During his presentation at the 3M global headquarters in Saint Paul, Minnesota, Bekele passionately articulated his vision of turning the soap into a “symbol of hope, accessibility, and a world where skin cancer treatment is within reach for all”.
Over the coming five years, Bekele longs to perfect his invention and establish a non-profit organization dedicated to distributing his innovative creation to under-served communities, offering hope and a practical solution in the fight against skin cancer.

【推荐1】The traditional tent cities at festivals such as Glastonbury may never be the same again. In a victory of green business that is certain to appeal to environmentally-aware music-lovers, a design student is to receive financial support to produce eco-friendly tents made of cardboard that can be recycled after the bands and the crowds have gone home.
Major festivals such as Glastonbury throw away some 10,000 abandoned tents at the end of events each year. For his final year project at the University of the West of England, James Dunlop came up with a material that can be recycled. And to cope with the British summer, the cardboard has been made waterproof.
Taking inspiration from a Japanese architect, who has used cardboard to make big buildings including churches, Mr. Dunlop used cardboard material for his tents, which he called Myhabs.
The design won an award at the annual New Designers Exhibition after Mr. Dunlop graduated from his product design degree and he decided to try to turn it into a business.
To raise money for the idea, he toured the city's private companies which fund new business and found a supporter in the finance group Mint. He introduced his idea to four of Mint's directors and won their support. Mint has committed around £ 500,000 to Myhabs and taken a share of 30 percent in Mr. Dunlop's business. The first Myhabs should be tested at festivals this summer, before being marketed fully next year.
Mr. Dunlop said that the design, which accommodates two people, could have other uses, such as for disaster relief and housing for the London Olympics.
For music events, the cardboard houses will be ordered online and put up at the sites by the Myhabs team before the festivalgoers arrive and removed by the company afterwards. They can be personalized and the company will offer reductions on the expense if people agree to sell exterior advertising space.
The biggest festivals attract tens of thousands of participants, with Glastonbury having some 150,000 each year. Altogether there are around 100 annual music festivals where people camp in the UK. The events are becoming increasingly environmentally conscious.

【推荐3】For the past few years, several companies have tried self-cooling undershirts, wrist-worn cooling plates, and windowless cooling machines as extreme heat waves spread across the world. But so far, none seems quite as practical as the Coolify, a $150 wearable that hangs around your neck.
Torras, the company behind Coolify, says its product is different from those cheap neck fans, even if it looks similar on the surface. That’s largely because of its ceramic (陶瓷的) cooling plate that sits right behind your neck. By running the plate, the device creates a cooling sense. “Basically, a neck fan can sometimes just blow hot air around,” Torras spokesman Jackson Wightman says. “This is genuinely an air conditioner as a result of the cooling plate.”
The Coolify comes in smooth plastic and has circular speaker grilles (格栅) on either side of its horseshoe design, somewhat like a pair of headphones. Look through either grille, and you’ll see a fan that draws in air and pushes it out through the long pair of passages above.
The device runs on a built-in battery that charges via USB-C. Torras says the battery lasts between two hours and eight hours on a charge, depending on which of its three fan speeds (H/M/L) you select.
Spending $150 on this might seem expensive. But the real appeal of a device like Coolify---and of wearable air conditioners (A/C) in general---is that they can spare you from having to turn on the A/C just when one person is feeling hot. The Coolify fulfills that goal, so we could pay for it in the long run.

【推荐1】This is the SCIENCE IN THE NEWS, I'm Barbara Klein.
Animal experts say one of the world's most beautiful and rare kinds of big cat is close to disappearing from the wild. A study earlier this year found that about thirty Amur leopards (豹) still live free. The cats are also called Far Eastern leopards.
Recently, their number has been reduced by one, Some person shot a female Amur, then beat her to death. The animal's body was discovered last month in the Barsovy National Wildlife Refuge in eastern Russia.
An official of the World Wildlife Fund, Darron, said this was the third such killing in the area in the past fives years. Mr, Collins said the death of even one adult female is a huge loss for the endangered cat, He noted that the killing reduces the possibility for cubs (幼兽) or young.
It is not clear how many Amur leopards still live free. One population count was performed in February and March. Wildlife expert Dmitry Pikuuov led this study. It found evidence of seven to nine males. The study identified three to seven females without cubs, Four leopards were identified as females with cubs. In all, five or six cubs were recorded, Six to eight animals could not be identified.
Most of the land where the Amur leopard once lived was in China.New roads and climate change there threatened the animals. So did hunters who kill big cats for their body parts.
Mr. Pikuuov says adult Amurs need about five hundred square kilometers with good forests to survive. He said they also need a large and continuing supply of animals like deer for food. He believes the answer to saving the Amur leopard is for governments to provide protected spaces for wildlife.

【推荐2】A cancer diagnosis no longer means what it used to. Just a few decades ago, the survival rate beyond five years was less than 50%. Now, nearly 70% of those who get cancer survive that long. Why? Because, chemotherapy (化疗) and radiation (放疗) , once the only heavy hitters of cancer treatment, are being paired with or replaced by a slate of new drugs and treatments.
For example, the first medication for what was previously considered an “undruggable” lung cancer mutation was recently approved in the United States, Canada, Europe and the U. K.
And a brand-new precision chemotherapy drug delivered directly to breast cancer tumor cells is giving hope to patients.
An even bigger newsmaker has been the promise of a treatment called immunotherapy (免疫疗法) , as researchers around the world have discovered ways to harness the body’s own immune system to battle cancer cells.
Also driving hope is a focus on prevention. Decades of research and public education have led to greater awareness of how lifestyle changes can reduce our risk of developing cancer. According to an article from the journal Pharmaceutical Research , 90% to 95% of cancers can be attributed to environment and lifestyle, rather than to genetic factors.
Here are some of the advances scientists are making against cancer.
PREVENTION
Cervical cancer was once one of the most common women’s cancers. In recent decades, Pap test screening led to a decline. But a preventive tool in use for more than a decade— a vaccine against the human papilloma virus (HPV) , which is responsible for more than 95% of cervical cancer cases-has been a game changer. Here’s how:
Since 2006, when the vaccine was introduced in North America, HPV infections have dropped more than 80% among teen girls and young women in the United States.
A study published in 2021 found that in England, where the immunization program was introduced in 2008, cervical cancer has been almost completely eliminated in women born since 1995 (those who were vaccinated at ages 12 or 13) .
An 11-year Swedish study of 1. 7 million women published in 2020 indicated that women vaccinated before age 17 were 90% less likely to get cervical cancer.
In March 2022, Australia announced that it was on track to become the first country to eliminate the cancer.
The World Health Organization’s goal is for 90% of girls to be vaccinated globally by 2030, eventually eliminating cervical cancer entirely.

【推荐3】“The world’s loneliest elephant” Kaavan, has reached Cambodia—on a flight of over 4,000km from Pakistan—and will spend his days at the Cambodia Wildlife Sanctuary in the country’s northwest.
Animal experts began the task of airlifting Kaavan on November 29. His departure from Pakistan marks the end of a campaign led by local activists and American singer and actress Cher, who has been campaigning for the elephant’s freedom since 2016. She is the co-founder of the NGO Free The Wild, which has played an important role in Kaavan’s relocation. Earlier in October, a veterinarian(兽医) from Four Paws, Dr Amir Khalil, took the responsibility of moving Kaavan, whose rescue has been described as “the heaviest one” the organisation has undertaken. Cher tweeted to thank Pakistan’s prime minister for making the rescue possible.
A special crate(板条箱) was especially built for the elephant, who weighs more than five tons and is more than three metres high. Kaavan was also trained by an elephant expert for several weeks to make sure that he could enter the crate safely. On the journey, Kaavan was accompanied by wildlife veterinarians and over 200kg of food. Kaavan is also Pakistan’s last Asian elephant and with his departure, the zoo where he was housed for over three decades may close soon, because many animals have been reported missing or dead in recent years. The zoo has repeatedly made headlines for its increasingly awful conditions.
According to the animal welfare organisation Four Paws, Kaavan came to the Pakistan zoo 35 years ago and shared his room with Saheli. After his “only companion” Saheli died in 2012, Kaavan was reported to be listless and even started showing signs of mental illness.
Luckily, Kaavan has found his relocation. Cambodian deputy environment minister Neth Pheaktra said, “Our zoo is pleased to welcome Kaavan. No longer will he be the world’s loneliest elephant. We expect to breed Kaavan with local elephants. This is an effort to save the gene.”
