Being diagnosed with diabetes was once considered a death sentence. Once people learned they had the disease, they usually died within a few months or a few years if patients followed extreme diets. This dire situation changed after Dr. Frederick Banting and his assistant, Charles Best, discovered how to isolate insulin on July 27, 1921.
Insulin is produced in the organ called the pancreas. It is a necessary hormone required by our bodies to regulate the sugar levels in our blood. People with diabetes are unable to produce insulin or adequate amounts of insulin. Without insulin, nutrients cannot be correctly distributed to vital organs throughout the body. As a result, these organs slowly shut down until the body dies. Therefore, it is essential that diabetic people regularly receive insulin shots to survive.
At the turn of the 20th century, scientists first discovered that the pancreas was responsible for producing insulin. In tests, animals that had their pancreas removed showed common symptoms of diabetes. After this discovery, the question then became how to isolate insulin from the pancreas and how to administer it to patients with diabetes.

In 1921, Dr. Banting and Best figured out how to extract insulin from a dog’s pancreas. They later used the insulin to treat another dog with diabetes successfully. In 1922, a more refined form of insulin was isolated from the pancreases of cattle. This insulin was then administered as shots to people suffering from diabetes. The method pioneered by Dr. Banting and Best benefits millions of people with diabetes. Dr. Banting was therefore awarded a Nobel Prize at age 32, remaining the youngest winner in the field.
人們一度認為被診斷出糖尿病就是被判了死刑。一旦得知自己患有這個疾病，他們通常會在幾個月內死亡，如果病患遵循極嚴格的飲食法或許可多活幾年。這樣嚴峻的狀況在弗雷德里克．班廷醫師和他的助理查爾斯．貝斯特於一九二一年七月二十七日發現如何分離胰島素後改變了。
胰島素是由叫作胰臟的器官所製造，它是我們身體調節血液中血糖濃度的必要賀爾蒙。糖尿病患無法製造胰島素或無法製造足夠的胰島素。少了胰島素，養分就無法正確地被分送到身體的重要器官。因此，這些器官會慢慢地衰竭，直到身體死去。所以，糖尿病患者為了活下來，定期接受胰島素注射是必要的。
在二十世紀初，科學家首次發現胰臟負責製造胰島素。在實驗中，被移除胰臟的動物會出現糖尿病的常見症狀。在這項發現之後，問題變成如何從胰臟分離出胰島素，以及如何將其施用在糖尿病患身上。
在一九二一年，班廷醫師和貝斯特理解了如何從狗狗的胰臟萃取出胰島素，他們之後用該胰島素成功治療了另一隻患有糖尿病的狗狗。在一九二二年，更精煉的胰島素從牛隻的胰臟分離出來，這種胰島素之後以注射的方式施用在罹患糖尿病的人們身上。班廷醫師和貝斯特開創的方法造福了上百萬名糖尿病患。班廷醫師也因此在三十二歲時被授予諾貝爾獎，至今仍是該領域最年輕的得主。

An automated human washing machine was one of the highlights at the Osaka Kansai Expo, giving visitors a glimpse into the future of personal hygiene technology. As part of the event, 1,000 randomly selected visitors were given the chance to try out this cleansing system. The machine operates as a capsule-like chamber where warm water filled with microscopic bubbles gently washes away dirt. The 15-minute process also includes a drying phase, removing the need for users to dry themselves manually. Equipped with advanced sensors, the device monitors the user’s biological data, such as their pulse, to adjust water temperature and other settings
Britain’s National Gallery announced on Sept. 9 that it will use a whopping ￡375m (US$510m) in donations to open a new wing that, for the first time, will include modern art. Founded in 1824, the gallery has amassed a centuries-spanning collection of Western paintings by artists from Leonardo da Vinci to J.M.W Turner and Vincent van Gogh — but almost nothing created after the year 1900. The modern era has been left to other galleries, including London’s Tate Modern. That will change when the gallery opens a new wing to be constructed on land beside its Trafalgar Square site that is currently
Firefighters might face an increased risk of developing “glioma,” a type of brain cancer, due to certain chemicals encountered on the job. A recent study analyzed glioma cases and found clear connections between the genetic patterns of affected firefighters and their exposure to these harmful substances. The study found that firefighters exhibited significantly higher levels of specific mutational signatures in their glioma cells compared to individuals in other occupations. These signatures — unique patterns of genetic changes in DNA — help scientists trace the source of mutations. Earlier research has associated these mutations with certain chemicals found in fire
