每日英語跟讀 Ep.789: About Science - ’Earth sandwich’ made by two men 20,000km apart
Sierra and Naude have created an "Earth sandwich" - by placing bread on precise points, either side of the planet, at the same time.
塞拉與諾德創造了1個「地球三明治」，透過將麵包同時擺在地球兩側精確的點上。
Naude from New Zealand wanted to make one for years, but had struggled to find someone in Spain, on the other side of the globe.
紐西蘭的諾德想做地球三明治好幾年了，他花費許多心力尋找一個在地球另一端─西班牙的人。
Two months ago, he posted on the Spain section of the online message board Reddit. He got "a few replies" and found one person close to the precise location.
2個月前，他在線上留言版Reddit的西班牙區塊發文後，他收到一些回覆，並且找到一個距離該確切位置較近的人。
The men used longitude and latitude to make sure they were precisely opposite.
他們利用經緯度確保彼此在地球另一端的精準「對面」。
According to World Atlas, only around 15% of "territorial land" is antipodal to other land. Naude only had to travel a few hundred metres to find a suitable public spot on his side of the world. Mr Sierra had to travel 11 km .
根據世界地圖，只有約15％「國家屬地」的對面也是土地。在諾德這側，他只需要移動幾百公尺，就可以找到合適的公共場所。塞拉則必須移動11公里。

Human ’screenome’ may give insight into human health 人類「螢幕特質」可探究人類健康
To understand how people use digital media, researchers need to move beyond screen time and capture everything we do and see on our screens.
要了解人們如何使用數位媒體，研究者必須超越螢幕的使用時間，進一步截錄一切我們在螢幕上的所為與所見。
Digital media — in particular, social media — have powerful and invariable effects on human behaviour. Policies and advice must be informed by accurate assessments of media use. These should involve moment-by-moment capture of what people are doing and when, and machine analysis of the content on their screens and the order in which it appears.
數位媒體，尤其是社群媒體，對人類的行為具有威力強大且不會消失的影響。政策和報告必須根據精確的媒體使用評估。而這些評量應該包括時刻截錄人們在什麼時候做了哪些事情，機器分析螢幕顯示的內容與指示。
According to a 2019 systematic review and meta-analysis, over the past 12 years, 226 studies have examined how media use is related to psychological well-being.
根據一項2019年的系統性回顧與統合分析，過去逾12年來，已有226項研究驗證媒體使用與心理福祉有關聯性。
The meta-analysis found almost no systematic relationship between people’s levels of exposure to digital media and their well-being. But almost all of these 226 studies used responses to interviews or questionnaires about how long people had spent on social media.
統合分析發現，人們接觸數位媒體的程度，與他們的心理福祉之間，幾乎沒有一致的關聯性。但226項研究中，幾乎所有研究都使用訪談或問卷調查，讓人們回答曾花多少時間在社群媒體上。
