The larger your brain is, the more friends you have. This is what is being said by a team of researchers from the University of Oxford.
Keeping up friendships takes brain power, research found, and people with real friends — as opposed to pals on social network sites — have to employ more cognitive skills to understand what someone is thinking.
Researchers have found a link between the number of friends people have and the size of their orbital prefrontal cortex. Tests were conducted on 40 people, with scientists taking anatomical magnetic resonance (MR) images of their brains to measure the size of their prefrontal cortex, which is used for high-level thinking.

Participants were asked to make a list of people they had social — rather than professional — contact with over a seven-day period. They also took a test to determine how competent they were at “mentalizing,” which is the capacity to understand what another person is thinking — a crucial aspect in how people handle the social world.
Results — published in the journal Proceedings of the Royal Society B — showed a connection between people with a large friendship group and a larger prefrontal cortex.

你的腦越大,你就有越多朋友:牛津大學研究團隊是這麼說的。
研究發現,保持友誼耗費大腦的力量,而且擁有真正的朋友--而非社群網站上的夥伴-必須運用更多認知技巧來了解某人在想什麼。
研究人員發現朋友數與大腦前額葉皮質區的大小有關聯。科學家在四十人身上測試,以核磁共振攝影掃描他們的大腦,測量他們用來進行高層級思考的前額葉的尺寸。
參與者被要求列出他們在七天內有社交接觸而非工作接觸的人名,他們也參與測試,了解他們的「認知」能力有多強,所謂的認知能力就是了解其他人在想什麼的能力,這是人們應對社交世界的一個關鍵面向。
刊登在《皇家學會學報—生物學》的研究結果顯示,朋友群很大的人,前額葉也大。

The strongest earthquake to hit Taiwan in 25 years killed at least 16 people and damaged dozens of buildings, but the destruction was largely contained thanks to decades of preparedness work. Taiwan sits on the “Ring of Fire,” an arc of intense seismic activity along the Pacific Rim, and — much like neighboring Japan — has a long history of catastrophic quakes. How does April 3 compare with other recent quakes? The April 3 earthquake, which measured 7.4 on the moment magnitude scale, was felt across Taiwan. It was the most severe since a 7.6 magnitude quake in 1999 killed
A: Artificial intelligence technology has been causing controversy lately: a student was caught cheating with AI to win the grand prize in an art contest. B: That’s so absurd. Does this mean that AI paints better than humans? A: Maybe. Luckily, the student was later disqualified. B: And more absurdly, it’s becoming more and more popular to use AI technology to “resurrect” people. A: Yeah, some netizens even posted videos featuring the late singer CoCo Lee, who was “resurrected” by them with AI software. A: 人工智慧的爭議不斷,有學生違規使用AI參加美術展,甚至贏得首獎。 B: 真誇張,這是不是代表AI比人類還強大? A: 或許吧,幸好得獎資格被取消。 B: 還有更誇張的︰讓死者重現的「AI復活」技術越來越熱門。 A: 對啊,還有網友製作已故歌后李玟「復活」的影片呢! (By Eddy Chang, Taipei Times/台北時報張聖恩)
Around the time of the Dragon Boat Festival in June, the streets of Taiwan are filled with the delightful aroma of zongzi, a traditional snack made of sticky rice wrapped in leaves. The leaves are folded into a cone and then filled with sticky rice and other ingredients such as braised pork belly, peanuts and salted duck egg yolks. The filled leaves are then tightly tied with kitchen twine and ready for cooking. 每到六月端午時節,街頭巷尾就會飄出粽子的香氣。粽子是將糯米包進粽葉的傳統美食,先將粽葉折成圓錐狀塞入糯米,以及紅燒肉、花生、鹹鴨蛋黃等配料,用棉線綁緊後即可烹煮。 Dragon Boat Festival (n. phr.) 端午節 aroma
It’s another school day with the same ritual. You wake up to your smartphone’s alarm, scroll through messages during your commute, and listen to your favorite playlist with your wireless earbuds between classes. These devices, integrated smoothly into your daily routine, certainly make life more convenient. However, where do these devices end up after you replace them? In fact, the issue of electronic waste is a growing global concern. According to the United Nations, in 2019 alone, we generated an astonishing 53.6 million tons of e-waste—an average of 7.3kg per person. Projections hint at the figure soaring to 110
