Scientists at Linkoping University in Sweden said that a "brain of gold" might just be what we need to fight nervous system diseases. The plan is to put gold electrodes (电极) into the affected part of the brain. They will act as "telephone operators" between nerve cells and electronic medical devices, enabling communication so that the nervous system can function normally.

Treatment plans that involve connecting medical devices to the brain already exist. However, the electrodes used are usually made of hard metals, while the brain is like a jelly that "shakes" at the body's slightest movement.

"As the body is constantly in motion, achieving close contact between something that is hard and something that is soft and breakable becomes a problem," explained Klas Tybrandt, one of the scientists.

This is why the Swedish scientists are using a new material called "gold nanowires" (金纳米线). As the name suggests, these are long, extremely thin gold threads — 1,000 times thinner than human hair. By putting them into rubber, the scientists have successfully created electrodes that are soft enough to connect comfortably with the human brain.

Gold can be made into structures as small as nanowires. According to Live Science, gold can be stretched, pressed or even rolled into all kinds of shapes without breaking. What's more, gold doesn't react with other chemicals in the human brain, making it a safe choice. Once placed in the brain, gold nanowires can last for at least three years, which is longer than many materials currently in use.

Aware of Aubrey's problem, her band director proposed her for Tech Engineering for Kids, a program which is run through a junior-level engineering course of the Tennessee Tech University. It involves students working in teams to design a form of custom assistive technology for children with special needs. Up to now, they have created toys and devices for children with sensory disorder.

Learning about Aubrey's story, a team of ten engineering students of the program decided to create 3D-printed prostheses (义肢) specifically designed for drumming. They would send a certain design to Aubrey, who would then provide feedback, like "I think this is good, but it's a little bit long. Could it be shortened?' or "It's a little bit hot on my arm. Could you potentially, like, make it a little bit more breathable?" The team created about six iterations of the prostheses until they were satisfied with the final product, which was not only hard-wearing but also flexible, allowing for drumstick attachments on both arms. This innovation not only improved sound quality but also provided the flexibility needed for advanced drumming techniques.

Aubrey was very grateful for this technical solution. "I was really excited that I was going to be able to use the new prostheses and try them out," she remarked. "They are becoming a very useful and resourceful tool to help me with my drumming." With her newfound drumming freedom, Aubrey sets her sights on mastering a full drum set. Meanwhile. Tech Engineering for Kids readies itself to extend its reach, bridging the gap between limitations and ambitions through technology.

Last week, a strong storm the small village of Greenfield. It felt the world was shaking, and many homes were destroyed. People were worried, but they tried to remain so they could think clearly and decide what to do next.

The of the storm could be seen everywhere. Trees were lying on the roads, buildings were damaged, and people needed help quickly. Despite everything, they worked hard to keep a attitude and encourage one another during the difficult time.

The teams arrived to help people who were trapped in their houses. Everyone made a great to solve the problems together. Food, water, and other supplies were to those in need.

In the end, most people the storm because everyone worked together and supported each other. This showed that life is hard, people can achieve a lot by working as a team.

The programme attracted an of almost twenty million.

Recently, a new exhibition building at the Sanxingdui Museum in Guanghan, Sichuan province, has become an immediate tourist hot spot. The exhibitions attract many visitors, (present) the unique culture of over 3,000 years ago.

For those who cannot make to Guanghan, an exciting exhibition based on digital technology, titled Hello Sanxingdui, provides them a different chance. It is running at the Longfu Art Museum in Beijing until Feb. 28. It offers an (education) and artistic time travel experience. The journey (begin) with a brief timeline of texts, photos and videos, showing how Sanxingdui was first discovered in the 1920s, many objects were found by farmers.

Tan Ping, one of the producers of Hello Sanxingdui, says it is of great importance to inform the public about archaeological (discovery) and developments in relevant research, while it relies on new ideas and techniques (bring) people new cultural experiences. He says exhibition like Hello Sanxingdui will help visitors know the life the creativity of the people in the Shu kingdom.
