Just like fingerprints, your breathing patterns may serve as a definitive identifier. In a recent study, scientists have demonstrated an astonishing 96.8% accuracy in identifying individuals based on their respiratory patterns. This revelation could open up new possibilities in biometrics and personalized health monitoring.
The notion of using individual breathing patterns as a distinct biological signature has long been a topic of discussion within the respiratory science community, yet a practical method for measurement remained elusive. This changed with the invention of a tiny, wearable device capable of extended recording. Researchers deployed a lightweight tube designed to fit inside the participant’s nose to track nasal airflow over 24 hours. From an initial study involving 97 participants, the team found that just one hour of recording yielded a 43% identification accuracy, which soared to 96.8% over a 24-hour period. A follow-up study on 42 participants revealed that these unique respiratory characteristics remained stable and distinguishable for up to two years, highlighting their potential as a long-term biometric marker.
如同指紋一樣，你的呼吸模式或許可作為可靠的識別特徵。近期一項研究中，科學家證明了基於呼吸模式識別個人的準確率高達驚人的 96.8%。這項發現可能為生物特徵辨識和個人化健康監測開闢新的可能性。

將個人呼吸模式作為截然不同的生物特徵這一概念一直是呼吸科學界熱切討論的議題，但始終難有可行的測量方法。這種情況隨著一種能長時間記錄的小型穿戴裝置的發明而改變了。研究人員有效運用一種設計來放入受試者鼻腔內的輕型導管，追蹤二十四小時以來鼻腔的氣流。在有九十七名受試者參與的初步研究中，該研究團隊發現，僅記錄一小時就能達到 43% 的辨識準確率，而到了二十四小時，準確率則飆升至 96.8%。針對四十二名受試者的後續追蹤研究顯示，這些獨特的呼吸特徵在長達兩年來仍舊保持穩定且可被辨識，因而凸顯了其作為長期生物辨識標記的潛力。

For many people in Taiwan, childhood memories of rural life include pig pens standing beside family homes. Leftover rice, vegetable scraps and soup from daily meals were poured into buckets and fed to pigs. This practice of feeding pigs with household food waste was once a common way of life, both an economic choice and an expression of agricultural society’s deep respect for conserving resources. From a practical standpoint, pigs are omnivorous animals capable of efficiently digesting food scraps that humans can no longer eat. For rural households, food waste cost almost nothing, yet it could be converted into pork, a
Tango unfolds in a dimly lit room, where a haunting melody ushers two dancers into a close embrace. Here, music and movement merge into a silent yet passionate conversation, expressing longing, memory and shared purpose. What makes tango truly magical is the deep interaction and spontaneous improvisation between partners. Tango began in the late 19th century in Buenos Aires, Argentina’s bustling capital. Born in the poor working-class neighborhoods and busy port areas, this dance emerged from a melting pot of cultures. European immigrants, African slaves and local residents all contributed to its unique character. From these rich influences, tango
A: What show are you watching online? B: I’m watching “Fly Me to the Moon & Back” – an exhibition launched by the Taipei Music Center (TMC) to commemorate the late singer Tom Chang. A: Known for his sky-high notes, Chang is praised as one of the best singers in the 1990s. His death at the age of 31 was a major loss indeed. B: And I’m so glad that we went to the TMC’s 90s-themed concert last Friday. I finally saw the iconic “Godmother of Rock” WaWa perform live. A: This year-end show also featured singers Princess Ai, Bii, Wayne Huang, PoLin and
