A significant breakthrough has recently occurred in the race to produce clean energy. Scientists at a laboratory in the US were able to create a fusion reaction that produced more energy *than was required to make it. Experts around the world agree that this incredible development proves that fusion power can one day be a practical energy option.(*此處的than為準關係代名詞,等同於than the energy which/that。)
“Fusion power” is a type of nuclear energy source like “fission power,” which is currently a common source of energy across the globe. While fission power involves splitting a large atom to produce energy, fusion power creates energy by combining smaller atoms together. It makes energy the same way the Sun and stars do.
One important thing to note is that fusion power doesn’t create harmful long-term radioactive waste and is unlikely to cause dangerous power plant meltdowns like fission power. That’s why fusion power has been described as the “holy grail” of sustainable energy.

Despite this critical development, there are still many obstacles to get over before fusion power becomes a reality. For one thing, the energy produced in the above-mentioned experiment was just enough to boil a few water kettles. It is incredibly difficult to sustain a fusion reaction. Temperatures need to be higher than the Sun’s center, and the pressure should also be greater than the Earth’s atmosphere before atoms will merge, not to mention the costs of building and maintaining all the highly-technical equipment. Still, many in the scientific community are optimistic about what the future of fusion power holds.
最近,在製造乾淨能源的競賽中有一項重大突破出現了。美國一間實驗室的科學家得以製造出核融合反應,其產生的能量比要製造出該反應所需的能量還多。全世界的專家皆贊同,這令人難以置信的發展證明了核融合能源有朝一日會是能實際運用的能源選擇。
「核融合能源」跟「核分裂能源」一樣是一種核能源,核分裂能源是一種目前在全世界很常見的能量來源。核分裂能源需要分裂一個大原子來產生能源,核融合能源則是藉由結合較小的原子來產生能源。其製造能源的方式跟太陽和恆星一樣。
有一件值得注意的重要事情是,核融合能源不會產生有害的長期放射性廢棄物,也不太可能像核分裂能源一樣造成危險的核電廠熔毀。那就是為什麼核融合能源被形容為永續能源的「聖杯」。
儘管有了這項關鍵性的發展,在核融合能源成真以前,還是有許多障礙要克服。首先,在上述實驗中所產生的能源只夠用來煮幾壺水。要維持核融合反應極度困難。在原子融合之前,溫度須高於太陽中心的溫度,而壓力也應該要比地球大氣還大,更別提建造和維護所有高技術性設備的花費。然而,科學界很多人還是對於核融合能源未來的發展樂觀以待。

A Cameroon-flagged cargo vessel “Shunxin-39” was believed to have caused damage to an undersea cable of Taiwan telecoms operator Chunghwa Telecom on the morning of Jan. 3. It was suspected that the Chinese merchant ship, which was registered with the nationality of another country, deliberately cut off the cable by dragging the anchor over it. While the incident is still under investigation, China has a long history of using maritime tactics to sabotage Taiwan’s infrastructure. In February last year, two cables linking Taiwan to its outlying Matsu Islands were damaged within days of each other by a Chinese fishing
Scientists have made a groundbreaking discovery in the depths of the Pacific Ocean: oxygen production without the involvement of living organisms. Four kilometers below the surface where sunlight cannot reach, researchers have found metallic lumps generating what they term “dark oxygen.” This form of oxygen is produced through a process independent of photosynthesis. Unlike the traditional photosynthesis process, where organisms use sunlight, carbon dioxide, and water to create energy and oxygen, the newly discovered phenomenon operates in complete darkness. The accidental finding occurred during a study of metal-rich lumps in an abyssal plain between Hawaii and Mexico. These lumps, known as
Have you ever dreamed of using an entire city as your training ground, effortlessly moving across walls, buildings, stairs, and obstacles? This is not just a fantasy from the movies. In cities around the world, a group of enthusiasts practice this seemingly impossible sport — “parkour.” The origins of parkour can be traced back to 20th-century France. A military officer named Georges-Hebert witnessed the incredible physical abilities of local residents in Africa, which inspired him to create the Methode Naturelle, or natural method. This training method cleverly combined climbing, running, and swimming with artificial barriers to mimic nature. Later, David Belle

Normally, oxygen rates would decrease as marine organisms consume it, but the result was contrary to expectations. The unexpected outcome prompted the team to further investigate the phenomenon. Researchers found the lumps emitted an electric charge similar to that of a AA battery. This charge is believed to trigger a process that splits seawater into hydrogen and oxygen, accounting for the increase. Traditional perspectives propose that oxygen production began around three billion years ago through photosynthesis by ancient
