1 . Plastic is everywhere, from the Arctic ice to vital organs in the human body. In fact, previous estimates suggest that the average person swallows a credit card-worth of microscopic plastic particles(颗粒) every week. But new research shows that this could actually be an understatement.

Microplastics are plastics smaller than 5 millimeters, found in industrial waste, beauty products, and formed during the degradation of larger plastic pieces. Over time, they break down into even smaller nanoplastics. These tiny particles can pass through our intestines and lungs into our bloodstreams, reaching vital organs like the heart and brain.

While the idea of eating plastic is unsettling in itself, the major concern here is that these plastic particles contain chemicals that can interrupt our body’s natural release of hormones, potentially increasing our risk of reproductive disorders and certain cancers. They can also carry toxins(毒素) on their surface like heavy metals.

In the past, researchers have shown bottled water can contain tens of thousands of identifiable plastic fragments in a single container. However, until recently, only the larger microplastics were detectable with available measuring tools, leaving the area of nanoplastics largely a mystery.

Using Raman microscopy (显微镜学), capable of detecting particles down to the size of a flu virus, the team measured an average of 240, 000 particles of plastic per liter of bottled water, 90 percent of which were nanoplastics, a revelation 10 to 100 times larger than previous estimates.

These plastics likely originate from the bottle material, filters used to “purify” the water, and the source water itself. “It is not totally unexpected to find so much of this stuff, ” the study’s lead author, Columbia graduate student Naixin Qian, said in a statement. His team hopes to expand their research into tap water and other water sources to better inform our exposure to these potentially dangerous particles. “The idea is that the smaller things get, the more of them I reveal, ” he added.

2 . Could you manage without the internet for four and a half years? That’s exactly what the actress Selena Gomez has done in a bid to improve her mental health.

She has spoken extensively about the relationship between her social media usage and mental well-being, recalling feeling like “an addict” as to becoming Instagram’s most followed user in 2016. “Indeed, I regret quitting from social media that late”, says she. “The unnecessary hate and comparisons went away once I put my phone down.”

However, the increasing digitization (数字化) means that everything from paying a bill to even making a phone call is at the mercy of the internet. Actively opting (选择) out of the internet becomes a matter of privilege. Ms Gomez’s multi-millionaire status has allowed her to take the “social” out of social media. The fact that she’s still the second most-followed woman on Instagram suggests it’s entirely possible to maintain a significant web profile to promote various projects by way of a dedicated team — without being exposed to the cruel comments.

It goes without saying that this is fundamentally different from how the rest of us without beauty deals and films to publicize use the likes of Instagram and Twitter, but even the concept of a digital detox (戒瘾) requires having a device and connectivity to choose to disconnect from.

The UK’s digital divide has worsened over the past two years, leaving poorer families without broadband connections in their homes. Digital exclusion (数字隔绝) is a major threat to wider societal equality in the UK.

Consequently, it’s worth bearing in mind that while deleting all social media accounts will undoubtedly make some feel infinitely better, many other people benefit from the strong sense of community that sharing platforms can develop. Greater resources and initiatives are needed to provide the underprivileged with the connectivity they desperately need to learn, work and live. It’s crucial that people feeling social media is harmful to their mental health are allowed to switch off and for those living in digital exclusion to be able to switch on primarily.

3 . Why do we talk the way we do? It might date back to when our ancestors left the jungle for the open plain. Between 5.3 million and 16 million years ago, Africa’s landscapes changed from thick, leafy forests to wide-open grasslands. This environmental change pushed our ancestors out of the trees and onto the ground. Along with all of the physical and behavioral changes this may have caused, researchers also believe it may have changed the way we speak.

“Open landscapes provide us with fewer objects to affect signal communication, meaning our voices can travel further compared with that in thick forests,” Charlotte Gannon, a researcher who studies language development, told Newsweek. “The move to these open spaces may have increased the effectiveness of our communication.”

By comparing the vocal calls of the orangutan (大猩猩) , Gannon and her team were able to establish how different calls could travel across different landscapes. In their study, the team played 487 calls from orangutans and measured their audibility (可听度) at set length over an overall distance of over 1,300 feet in the South African plain.

“Our results were surprising,” Gannon said, “The rule of sound spread suggests that lower-frequency (低频率) sounds (the grumphs) would have traveled further than higher-frequency sounds (the kiss squeaks). Our results actually found the opposite to this.” In these environmental settings, consonant (辅音)-like calls traveled a lot further than vowel (元音) -like calls. Actually, around 80 percent of consonant-based calls were audible at 1,300 feet, compared to only 20 percent of vowel-based calls.

Gannon said these results highlight the importance of studying living orangutan to learn about our species’ history. “We can view them as time machines that allow us to recreate key moments of our history so we can learn more about the development of our language,” Gannon said. “Despite their popularity in modern languages, consonants have often been forgotten when discussing speech development. Our research highlights not only their presence in ancient times but their importance to the development of language.”

5 . Two very different movies were released on July 21 this summer in the West, bringing record numbers of people into cinemas as the “Barbenheimer (芭比海默)” trend took over social media.

Barbie and Oppenheimer have been huge hits around the world, with Barbie alone making over 1 billion US dollars just 17 days after release. This makes it Wamer Bros studio’s fastest movie to reach $1 billion and the film’s director, Greta Gerwig, the first-ever solo female filmmaker with a billion-dollar film.

Barbie and Oppenheimer are an interesting pair because of how different they are from one another. Barbie is about a famous toy coming to life and facing issues of sexism and finding her own identity. Meanwhile, Oppenheimer is a serious male-driven historical film about J. Robert Oppenheimer’s Manhattan Project and the development of the atomic bomb. The release of these two huge, wildly different movies on the same day led to the creation of countless memes (表情包) under the Barbenheimer hashtag. Filmgoers have even gone to see both movies one right after the other, with some dressing up in pink for Barbie going on to see Oppenheimer as well.

Meanwhile, people have found some of the “Barbenheimer” memes disturbing. Atomic bombs killed many people and they think the memes made light of a very dark time in history. But the films have brought a healthy boost to cinema ticket sales around the world, helping an industry that has faced many challenges in recent years. The increasing popularity of streaming services and the COVID-19 pandemic have kept people out of cinemas. Now, the strikes from writers and actors over concerns of pay and about the use of artificial intelligence by film studios are also having an impact. Add to that a public tired of yearly big movies about superheroes and fast cars, as declining ticket sales suggest.

Described as a historic moment for the movie industry. “‘Barbenheimer’ will go down as one of the biggest and unexpected milestones in the history of cinema,” Paul Dergarabedian at Comscore told CNN.

2023 Gotham Award Nominee for Breakthrough Figure(Raven Jackson)

One of the most visually striking, profoundly moving American moviemaking debuts(首次亮相) in years, Raven Jackson’s All Dirt Roads Taste of Salt is an eye-catching immersion into a young woman’s inner world, filmed and edited with an extraordinary attention to the tiniest detail. This impressionistic journey skips ahead and back through decades to tell the story of Mack, whose upbringing in rural Mississippi is touched by grace, dotted with heartbreak, and always carried high in the sky by the surrounding natural beauty. As she ages, she loses loved ones and gains others, while making decisions that change the course of her life, and that of her beloved sister. Relying on sounds and images to tell her story, and employing minimal dialogue, Jackson has created something breathtakingly quiet and ultimately transporting a spiritual respect to the moments, feelings, and connections that make a life. An A24 release.

10 . Have you ever wondered what happens to your mobile phones and laptops after you throw them out to make way for a newer model? According to its latest Global E-Waste Monitor, India is the third top producer of e-waste in the world. E-waste in Indian landfill goes on to pollute soil and groundwater, affecting food supply systems and water sources.

Thankfully, the country has a new group of artists who are changing these thrown mechanical items-from mobile phones to old televisions- into large murals (壁画) and artworks to creatively show their concern for the waste problem.

Over the past quarter of a century, Mumbai’s Haribaabu Naatesan has transformed hundreds of tonnes of e-waste into art, integrating elements from nature and industry. “I get my waste material from friends, relatives and neighbours who know my interest in e-art and send me bags of thrown electronic appliances,” says Naatesan. Over his career, he has created huge murals for several companies. He has also showed his work at the India Art Fair, as well as several other national displays.

Another artist Vishwanath Davangere has also long worked with e-waste. He likes to take apart old laptops and reassemble (重新组装) them into birds, animals and plants. After retirement, he started pursuing this hobby more seriously and started selling his creations across the world. His most outstanding works include a robotic Egyptian statue with glowing red eyes and a Milky Way made from keyboard keys. He hopes to enable others to reconsider their own consumption habits and make more environmentally conscious choices.

“By giving e-waste a second chance, I aim to raise awareness about the environmental impact of electronic waste.” says Davangare, who today has a collection of more than 600 eco-art objects.
