A small robot that can change its shape and produce heat shows potential in targeting cancer cells and preventing internal bleeding. It can also be used for delivering drugs directly to tumors ( 肿 瘤 ) or inaccessible areas within the human body. 

Researchers, led by Ren Hao Soon at the Max Planck Institute for Intelligent Systems in Stuttgart, Germany, developed a centimeter-sized robot inspired by pangolins (穿山甲). It is constructed with soft and magnetic (磁性的) materials, allowing the robot to change its shape. 

To enable movement, shape shifting, and heat generation, the researchers applied magnetic fields to the robot's metal parts. By adjusting the frequency of these fields, the robot was able to heat up and give out heat into its surroundings. The team observed that the robot's body temperature could be over 70℃.

In addition, the researchers used the robot's heat to deliver substances within a simulated (模拟的) stomach environment. They attached something simulating medicine capsules onto the robot, which dissolved upon heating, thereby releasing the goods. This technique holds promise for targeted drug delivery inside the body.

Soon, his team also tested the robot's ability to halt bleeding. They created wounds using a dead pig's stomach. By pumping blood through a small incision using a syringe, they simulated bleeding. Subsequently, the robot extended and covered the area, giving out heat to help stop bleeding.

According to Jake Abbott from the University of Utah, the robot could potentially be employed for targeted destruction of tumor cells, reducing the need for exposing large amounts of tissue to radiation or chemicals. By raising the robot's temperature to a level unsafe for normal cells and keeping it in place for a few minutes, cancer cells can be killed.

It's a sweet moment, as a chimp reaches up to kiss his mother's face. The touching photo was taken by the famous conservationist and activist Jane Goodall in 1993 in Gombe National Park in northwest Tanzania where she has studied chimpanzees for more than six decades.

The image is part of Vital Impacts consisting of a group of 100 photographers. The women-led non-profit was founded by award-winning photographer Ami Vitale and visual journalist Eileen Mignoni. They are selling fine arts images, most of which focus on wildlife and nature, with earnings benefiting conservation organizations including Jane Goodall Institute's Roots and Shoots program.

"Our purpose is to use photography to create awareness and understanding; to help us see that the survival of the planet is closely connected with our own survival. As photographers, we have a huge opportunity to inform and influence change, but pressing the shutter (快门) is just the start," Vitale said.

"For an image to have significance, it needs to reach people. To this end, we are working to get the photographs of Vital Impacts photographers and our students into high-profile media and exhibitions around the world. "

The organization gives special attention to photographers who are committed to the planet. Funds will be used to support global conservation and environmental initiatives and the group will offer two $20,000 environmental storytelling awards. 

Vital Impacts has raised more than $1.5 million from the sale of fine art prints since the organization was set up in late 2021. Some of its profits were donated to the organization Direct Relief, which shipped more than 1,400 tons of medical supplies worth $545 million to support 351 healthcare equipment in disaster zones. Other profits were able to provide fuel and vehicle assistance to support wildlife corridors (廊道), a monitoring program, and the restoration of the Snake River in the Pacific Northwest. 

Every Saturday night, all through that lazy spring, I used to take a rose to Miss Caroline Wellford. Every Saturday night, rain or shine, at exactly eight o'clock.

Miss Caroline was abandoned by her future husband Jeffrey Pinniman, who married Christine Marlowe, a younger and prettier girl. It almost became a scandal in our town. Miss Caroline could hear unkind things about her everywhere she went. For six months she had shut herself up in her house and seemed determined to turn herself into an odd old maid. She looked like a ghost that night when I delivered the first rose. "Hello, Jimmy," she said listlessly. When I handed her the box, she looked shocked — "For me?"

Again the next Saturday, at exactly the same time, I found myself delivering another rose to Miss Caroline. The third time she opened the door so quickly that I knew she must have been waiting. There was a little color in her cheeks and her hair no longer looked so straggly. 

The morning after my fourth trip to her house, Miss Caroline played the organ again in church. She held her head high with the rose pinned to her blouse. 

When I made my final trip to Miss Caroline's house, I said, as I handed her the box, "This is the last time I'll bring this, Miss Caroline. " She hesitated and invited me to come in and handed me a model of a sailing ship, exquisitely（精巧地）carved.

Fleeing back to the shop, I looked in the file where Mr. Olsen kept his untidy records, and I found what I was looking for. "Pinniman," it said, in Mr. Olsen's crabbed script.

The years went by, and one day I came again to Olsen's flower shop. My old boss and I talked a while. Out of curiosity, I asked, "D'you suppose that Mrs. Pinniman ever knew her husband was sending flowers to his old flame?" "Jeffrey Pinniman never even knew about it. " Mr. Olsen smiled, "It is a lady who said she wasn't going to sit around watching Miss Caroline make a martyr (长期受痛苦的人) of herself at her expense. "
