3 . Parkinson’s is a progressive brain disease which leads to shaky hands and slow movement, and there is no cure. Tai Chi, a traditional Chinese martial art that combines (结合) slow, gentle movements with deep breathing and relaxation, may be an effective means of reducing the suffering. Recently, the researchers say that those who practised the martial art twice a week had fewer complications (并发症) and better quality of life than those who didn’t. Experts say the findings back up previous studies on the benefits of exercise for those with Parkinson’s.
The study, from Shanghai Jiao Tong University School of Medicine, monitored the health of hundreds of Parkinson’s patients for up to five years. One group of 147 people practised regular Tai Chi while another group of 187 did not. The researchers found that the disease progressed more slowly in the Tai Chi group on measurements of symptoms (症状), movement and balance. This group also saw fewer falls, less back pain and dizziness, with memory and concentration problems also lower than in the other group. At the same time, sleep and quality of life continuously improved.
Prof. Alastair Noyce, professor in neurology and neuroepidemiology at Queen Mary University of London, called it “an important study”—the positive effects on aspects of motor (运动的) and non-motor functions are impressive — but said there were limitations in its design, and more tests were needed.
“We already recommend Tai Chi, as well as other forms of exercise, but understanding which forms of exercise are most beneficial is an important goal to improve the long-term management of patients,” he said.

4 . People tend to use trees for papermaking. But maybe electronics (电子) engineers are missing out on something here. “It turns out that two major building blocks of wood have a lot of electrical qualities,” says Magnus Berggren, a professor at Linköping University.
His team has been working to make parts for electronics from the forest. Right now, they’re focusing on two materials of trees. The first material is cellulose, which can make energy. Lignin, the second material, can store that energy, just as a battery does. The team has found when pressed, cellulose can produce electricity.
Some device must then store the electricity until it’s needed. Batteries can do this. But batteries aren’t very green. They have harmful materials. That’s where lignin comes in.
Batteries cause electrons to flow from one place to another, which can produce electricity. In a typical battery, one material must give electrons. The other must accept them. Lignin can do both. A weak acid (酸) encourages lignin to produce electrons. “With a metal wire (金属线) to guide those electrons, you’ll have electricity,” says Berggren.
Berggren’s team use this quality to create its new lignin-based battery. Typical batteries use a metal wire as a path to guide the flow of electrons into or out of the device. But since Berggren wants to make a battery of the forest, he looks for a natural way. Once again, he turns to cellulose.
This natural material can serve as a wire-like path for electrons. To make it work well, Berggren lines them with another chemical known as PEDOT, which isn’t from a tree. But when PEDOT is added to cellulose, they can conduct electricity like a wire. “With a weak acid, now you have a battery,” Berggren says. “And two of its three materials come from the forest.”
Berggren can imagine one day having mobile phone batteries made largely from forest products. Tree-based electronics might also be useful in lighting.

5 . Our two-year investigation into caged (关在笼中) tigers in America sent us through 32 US states—with some truly shocking experiences. But as the deadline neared, I still needed a powerful and hopeful image.
When we began our reporting in 2017—Sharon, writing; me taking photos; and our son, NickRuggia, filming—more tigers likely lived in cages in the US than remained in the wild. The number ranged from 5,000 to 10,000, but without strict government oversight, no one knew for sure.
Roadside zoos that allowed tourists to take pictures of young tigers were the main cause of what’s been called a US tiger crisis (危机). Caged cats often ended up in the illegal wildlife trade. Young tigers, parted from their mothers at birth, were fed poorly and touched by hundreds of people. When they grew too big and dangerous to pet at around 12 weeks, young tigers were put on show, or simply disappeared.
While we documented the unpleasant part of this industry, we also wanted to show the good life these impressive animals could have. With two weeks left before my deadline, I headed to the Wild Animal Sanctuary near Denver, where well-cared cats walked freely in their habitat.
There I met Clay, Daniel, and Enzo, three of 39 tigers rescued from an animal park in Oklahoma. These nearly grown cats raced beside our car, which I’d seen only in the wild. It was a hot July day and soon two of the cats jumped into a pool to cool off. The third rested beside them on the ground. I crossed the road to take a picture of them. Then quietly, I came up close, trying not to disturb (打扰) them. I had the shot.

6 . Leah Brown aged 36 fell several hundred feet from Oregon’s highest mountain right before the eyes of a group of volunteer rescue workers who rushed to her aid and helped save her life.
The woman was coming down a popular path (小路) on Mt. Hood, about 70 miles east of Portland, on Saturday morning, according to the local police. Mt. Hood is the highest in Oregon, standing at around11.240 feet.
The fall was seen by members of Portland Mountain Rescue (PMR), a volunteer organization focused on helping people in mountainous areas. The group called 911 and rushed to the woman, providing medical care. They helped keep the woman warm for seven hours as the police worked to get her off the mountain safely. Finally, the woman was evacuated (转移) to a parking lot at 9:30 pm and taken to a hospital.
The climber, Leah Brown, said she didn’t know what caused her fall. “I can only guess it was either an ice tool or a crampon (冰爪) that didn’t land and stick like it should have, so I became detached from the mountain,” Brown said. “The thing I’d like to most stress is my appreciation for the members of PMR who evacuated me and took good care of me the whole time,” Brown added. “They saved my life. ”
In a statement after the rescue, PMR warned of the dangerous winter conditions at the mountain. “The short days and lower temperatures mean that the snow tends to be very hard and icy, and the conditions tend to be much steeper. Climbing the mountain in icy conditions is much more difficult,” the group said.
