Lack of sleep has a potentially harmful effect on gene expression, according to a study out on Aug. 6 that sheds light on the link between sleep deficits and a wide range of health conditions.
Lack of adequate shut-eye had already been linked to conditions from heart disease and cognitive impairment to obesity. But sleep researcher Derk-Jan Dijk and his fellow researchers have delved into the molecular mechanisms behind the phenomenon, looking at how missed sleep leads to health problems.
They found that a week of sleeping six hours or less a night affects the expression of some 711 genes, including those involved in inflammation, immunity, and stress responses.

Compared with test subjects who were allowed to sleep as long as 10 hours a night, those who lacked sleep had irregularities in their genes’ circadian rhythms.

八月六日公布的一份研究說明睡眠不足與多項疾病的關聯性，根據研究，睡眠短缺可能有害基因表現。
缺乏足夠的闔眼已被與多項疾病連結，從心臟病、認知障礙到過胖等。但睡眠研究人員狄克與研究員同僚更深入這種現象背後的分子機制，研究睡眠不足如何導致健康問題。
他們發現，一週內每天睡眠不超過七小時，影響約七百十一種基因表現，包括與發炎、免疫、壓力反應等有關的基因。
此外，相較於一晚得以睡長達十小時的受試者，缺乏睡眠者的基因生理時鐘紊亂。

A: Yoasobi is a J-pop duo formed by Ayase and Ikura in 2019, and it’s loved by young people. Haven’t you heard? B: Oops, I’m feeling a little old. A: It sings the theme songs of “Oshi No Ko” (“My Idol’s Children”) and other TV series, leading it to gain popularity among young people. A: 除了2NE1、Rain、魔力紅，日本熱門樂團Yoasobi本週末也將連唱兩場。 B: Yoasobi樂團？ A: 這是由Ayase、Ikura在2019年組成的雙人團體，近年來大受年輕人歡迎！你沒聽過嗎？ B: 天啊我覺得自己老了。 A: 他們唱了《我推的孩子》等人氣影視作品主題曲，所以大受年輕人喜愛。 （By Eddy Chang, Taipei Times／台北時報張聖恩）
Chinese startup DeepSeek’s launch of its latest AI models, which it says are on a par or better than industry-leading models in the US at a fraction of the cost, is threatening to upset the technology world order. The company has attracted attention in global AI circles after writing in a paper last month that the training of DeepSeek-V3 required less than US$6 million worth of computing power from Nvidia H800 chips. DeepSeek’s AI Assistant, powered by DeepSeek-V3, has overtaken rival ChatGPT to become the top-rated free application available on Apple’s App Store in the US. This has raised doubts about the reasoning
The crimson hue of theater seats is a long-standing tradition that has persisted through centuries and across continents. This seemingly universal choice is influenced by a fascinating combination of historical, visual, and practical factors. Inspired by the lavish aesthetics of Italian opera houses, where red has been a dominant color, movie theaters often adopt the red color __1__—a tradition that emerged in the late 19th and early 20th centuries. Associated with power, the color red was used in opera houses to __2__ an image of sophistication and grandeur. As opera spread across Europe, more and more opera houses adopted
