The human body’s most remarkable and resilient parts are its bones, which are an awe-inspiring subject to explore. A fully developed human skeleton is composed of 206 bones and over 200 joints, accounting for around 20 percent of an adult’s body weight. Bones have various functions, including essential roles like protecting and supporting the body, producing blood cells and regulating hormones.
One of the most important components of bones is their mineral content. Bones are primarily composed of calcium, which provides their strength and durability. Apart from calcium, bones also contain other minerals such as phosphorus, which helps regulate calcium levels and assist in the formation of bone tissue.
From birth, our bones undergo constant regeneration throughout our entire lives. In fact, almost 100 percent of our skeleton is replaced within the first year of our lives, while as adults, our bones are rejuvenated by about 10 percent each year. This process is known as bone remodeling. It includes breaking down old or damaged bone tissue by cells known as osteoclasts, followed by the formation of new bone tissue by cells called osteoblasts. Bone remodeling maintains the structural integrity of the skeleton, as well as contributing to the body’s mineral balance.

However, bones can be vulnerable to damage. Factors such as age, poor nutrition and lack of exercise can disrupt the balance of bone remodeling, leading to bone loss and an increased risk of fractures. To ensure that our bones remain strong, we should adopt a balanced diet and consume foods containing vitamin D and calcium, like dairy products and green vegetables. Regular exercise and medical attention when required are also good ways to keep our bones healthy for years to come.

A request by the World Health Organization (WHO) for more information on a surge in respiratory illnesses and clusters of pneumonia in children in China has attracted global attention. Health authorities have not detected any unusual or novel pathogens, the WHO later said, and doctors and public health researchers say there is no reason for international alarm. Authorities in Taiwan, however, last week advised the elderly, very young and those with poor immunity to avoid travel to China. The following is what we know about the surge in illness in the world’s second most populous country so far, and why experts think there
Have you ever wondered about the odd name “eggplant” or heard of its bizarre nickname, the “mad apple”? The tales behind these names are just as unusual as the vegetable’s appearance. The name “eggplant” dates back to the 18th century. It wasn’t inspired by the familiar long, purple type we often see and enjoy in Taiwan. Instead, it was a unique variety, which was small, egg-shaped and white, that earned it its name. While the British were in India, this particular form caught their attention. It prompted them to adopt the term “eggplant.” Even though new eggplant varieties in
限水與限電是近年來辦公室有時需要面對的問題，當碰上這樣的狀況，該如何發出公告讓團隊隨之調整應對方式呢？我們一起來看看。 ★Part 2 continued from last Sunday（延續自上週日）: https://www.taipeitimes.com/News/lang Water Rationing Scheduled for Next Tuesday (20231024): We would like to bring to your attention that there will be water rationing in our office premises next Tuesday, from 0800 to 1900. This will affect our water supply throughout the day. Please take note and make necessary preparations.

IT部門本月正在配給印表機墨水。 Premise(s) 場所 附近的場所就用此字，戰爭片也常常用這個字來表示確保周圍場域安全，因為表示的是周圍的場域，所以通常會使用複數。 All employees must show their ID cards before entering the premises. 所有員工在進入場所之前都必須出示其身份證。 We are planning to expand our business premises next year. 我們計劃明年擴大我們的業務場所。 Preparation 準備 動詞是prepare，名詞則是preparation，通常搭配動詞片語為make/start preparations，因為需要準備的事物大抵上不會只有一項，故常用複數。 Preparations for
Have you ever taken off a sweater and felt a surprising shock? That’s static electricity, the buildup of an electric charge. It occurs when two items rub against each other, and electrons are transferred from one thing or person to another. If an object has an excess of electrons, it becomes negatively charged. On the other hand, when something has a lack of electrons, it naturally becomes positively charged. Opposite charges attract, so when a negatively charged object comes into contact with a positively charged one, the electrons will flow from the negative object to the positive one until the
