>Oscars' new diversity rules
Starting in 2024, the Academy of Motion Picture Arts and Sciences will only give the top Oscar to movies that are more diverse - either on screen or behind the scenes.
For movies to be eligible for the best-picture award, they'll have to adhere to two of four diversity categories, which cover everything from casting to marketing.
For example, to qualify in the "on-screen representation" category, movies must include a key cast member who's a minority, or focus the story on an underrepresented group.
The new standards come after years of criticism that the Academy Awards, Hollywood's highest honors, are too white and male.
In the 2020 ceremony, only one non-white actor was considered for an acting award, and the storylines of major films were mostly about men.
Cynthia Erivo, the only Black performer to receive a nomination for best actress, was recognized for playing a former slave.
辛西娅 • 埃里沃是唯一一位获得最佳女主角提名的黑人演员，饰演的角色是一个奴隶。
Other categories the Academy will consider when looking at diversity are whether the leadership and project teams are diverse, whether distribution or finance companies behind the film offer opportunities to underrepresented groups, and whether studios actively seek out non-white, female, LGBTQ+ or disabled audiences.
>Kite-makers see sales fly
While Italians sang songs from their balconies and windows to boost morale when they were stuck at home due to COVID-19 restrictions, Indians flew kites from their terraces and roof tops.
Ahsan Khan, a seller in Mumbai, says, "The period between April and August is usually the leanest [for kite sales], but this year, I have sold about 500,000 kites [during that time]."
He adds that neighboring Pakistan had also caught the kite-flying bug during its lockdown.
"I am even getting calls from Karachi and Lahore in Pakistan, from people offering to pay me double the usual amount."
Khan says that sales have been led by India's smaller cities and towns, as that is where more people have individual terraces or roof tops.
This is in contrast to the big cities, like Mumbai, where most people live in flats and have to share such outdoor areas.
These communal spaces were officially out of bounds during the lockdown.
>Full stop is 'intimidating'
Full stops intimidate young people when used in social media communication as they are interpreted as a sign of anger, according to linguistic experts.
Teenagers and those in their early 20s, classified as Generation Z, have grown up with smartphones, which they use to send short messages without full stops.
Linguistic experts are now investigating why teens interpret a correctly-punctuated text as a signal of irritation.
Linguist Dr Lauren Fonteyn of Leiden University in Holland, tweeted: "If you send a text message without a full stop, it's already obvious that you've concluded the message. So if you add that additional marker for completion, they will read something into it, and it tends to be a falling intonation or negative tone."
Unusually, texts ending in an exclamation point – such as "lmao!", "just a cheeky one!", "what body part even is that? I hope it's your arm!" – are deemed heartfelt or more profound.
>Study: the moon is rusting
The moon is turning red, and it's likely Earth's fault.
Our planet's atmosphere may be causing the moon to rust, new research finds.
Rust, also known as iron oxide, is a reddish compound that forms when iron is exposed to water and oxygen.
But not all celestial environments are optimal for rusting, especially our dry, atmosphere-free moon.
"It's very puzzling," the study's lead author, Shuai Li of the University of Hawaii, said in a statement. "The moon is a terrible environment for [rust] to form in."
Li was studying data from the JPL Moon Mineralogy Mapper when he realized that the poles of the moon had very different compositions from the rest of it.
He found that the moon's polar surfaces had iron-rich rocks with spectral signatures that matched that of hematite.
The mineral hematite, commonly found in Earth's surface, is a specific type of iron oxide, or rust, with the formula Fe2O3.
"At first, I totally didn't believe it. It shouldn't exist based on the conditions present on the moon," said co-author Abigail Fraeman, a planetary geoscientist at JPL. "But since we discovered water on the moon, people have been speculating that there could be a greater variety of minerals than we realize if that water had reacted with rocks."
The moon doesn't have an atmosphere of its own to provide sufficient amounts of oxygen, but it has trace amounts donated by Earth's atmosphere.
This terrestrial oxygen travels to the moon along an elongated extension of the planet's magnetic field called a "magnetotail."
Earth's magnetotail can reach all the way to the near side of the moon, where more of the hematite was found, according to the statement.
