Researchers have unveiled long “hidden” and finely detailed tattoo designs on the skin of ancient mummies from Peru, a study reports. Tattoos were a prevalent art form in pre-Hispanic South America, as attested by the discovery of mummified human remains in the region with preserved skin decoration that date back centuries, and even millennia.

While such body art works can provide insights into ancient cultures, tattoos are known to fade and bleed over time — a process compounded in mummies by the decay of the body. This often means that the original designs are difficult to make out.

In the latest study, published in the journal Proceedings of the National Academy of Sciences, a team of researchers used a technique known as laser-stimulated fluorescence (LSF) to examine tattoos on mummified individuals belonging to the pre-Hispanic Chancay culture of what is now coastal Peru.

The mummified remains that team of researchers examined were originally discovered in 1981 at the Cerro Colorado cemetery archaeological site in the Huaura Valley of Peru. The LSF technique revealed “exceptionally fine” and previously unknown details of the ancient tattoos.

The team managed to identify intricate geometric and zoomorphic (representing animal forms) designs that were “very surprising” because they demonstrate a higher degree of artistic complexity than any other existing Chancay artwork, including on pottery and the culture's renowned textiles. The art of tattooing was clearly important to the Chancay, as evidenced by the high proportion of tattooed individuals among known mummified remains from the ancient culture.

Text I: The speed of sound

Some music fans now know 15-second sped up snippets of songs better than the real thing. It’s thanks to an emerging trend on social media, particularly TikTok, of creators changing the tempo of popular songs by 25-30%, to accompany short viral videos of dances or other themes. This phenomenon presents a very modern challenge – how can singers create the next hit tune when the one people actually listen to might sound so different?

Sped-up listening emerged in the early 2000s as “Nightcore”, launched by a Norwegian DJ duo of the same name, who sped up a song’s pitch and speed. This is now commonplace on social media apps, where the speed of podcasts, voice notes, movies and more can be increased so that people can consume them in less time. But what people might not know is that unofficial sped-up or slowed down tunes are different to a professional remix because they are far shorter and can be easily made by anyone, including on TikTok, Instagram Reels and other apps.

In 2023, more than a third of Spotify listeners in the US sped up podcasts and nearly two-thirds played songs at a quicker tempo. The streaming service recently confirmed to the BBC that it was testing a new and more widespread feature that could potentially allow its customers to remix the tempo of songs and share them. In addition, some popstars are embracing this phenomenon. In November 2022, for example, fan-made sped-up versions of RAYE’s single “Escapism” helped the artist to achieve her first ever number one on the UK Official Singles Chart, nearly three months after its original release. Furthermore, Billie Eilish has also released official fast and slow versions of songs and Sabrina Carpenter’s hits “Please Please Please” and “Espresso” received similar treatment.

Dr Mary Beth Ray, an author focused on digital music culture, says short-form video platforms like TikTok “constrain our ways of listening into snippets, but those constraints also let you experience a track in a new way”. She also said that “short clips provide a quicker line to that dopamine rush social media wants us to feel – so there is an addictive element which we’re pushed towards.”

BBC Radio 1 DJ Maia Beth feels it's now getting hard for established labels and musicians to ignore this trend because it can sometimes feel like if they don't release the sped up version, then someone else will. Beth, who admits she can't imagine sitting and listening to a sped-up version of a song the whole way through, believes the trend shouldn't necessarily be a major distraction for musicians though. “Sped-up versions of tracks can help artists break through or go viral, although that initial success may not last,” she added.

TikTok says it has noticed an increase in the number of sped-up and slowed down versions of catalogue tracks taken off the platform, then become officially released. These official changed-tempo releases are now grouped together with the original song in the UK Official Singles Chart, along with remixes, acoustic and live versions, helping artists to climb the ranks.

That said, not everyone is happy with the trend. The popularity of speed-altered versions can make it harder to distinguish original from remix while altering an artist'sintended pacing, mood and tone. However, while some artists like them and others less so, it seems they are here to stay.

READ THE TEXT AND ANSWER THE QUESTION:

Chatbots could be used to steal data, says cybersecurity agency

The UK’s cybersecurity agency has warned that there is an increasing risk that chatbots could be manipulated by hackers.

The National Cyber Security Centre (NCSC) has said that individuals could manipulate the prompts of chatbots, which run on artificial intelligence by creating a language model and give answers to questions by users, through “prompt injection” attacks that would make them behave in an unintended manner.

The point of a chatbot is to mimic human-like conversations, which it has been trained to do through scraping large amounts of data. Commonly used in online banking or online shopping, chatbots are generally designed to handle simple requests.

Large language models, such as OpenAI’s ChatGPT and Google’s AI chatbot Bard, are trained using data that generates human-like responses to user prompts. Since chatbots are used to pass data to third-party applications and services, the NCSC has said that risks from malicious “prompt injection” will grow.

For instance, if a user inputs a statement or question that a language model is not familiar with, or if they find a combination of words to override the model’s original script or prompts, the user can cause the model to perform unintended actions.

Such inputs could cause a chatbot to generate offensive content or reveal confidential information in a system that accepts unchecked input.

According to the NCSC, prompt injection attacks can also cause real world consequences, if systems are not designed with security. The vulnerability of chatbots and the ease with which prompts can be manipulated could cause attacks, scams and data theft. The large language models are increasingly used to pass data to third-party applications and services, meaning the risks from malicious prompt injection will grow.

The NCSC said: “Prompt injection and data poisoning attacks can be extremely difficult to detect and mitigate. However, no model exists in isolation, so what we can do is design the whole system with security in mind.”

The NCSC said that cyber-attacks caused by artificial intelligence and machine learning that leaves systems vulnerable can be mitigated through designing for security and understanding the attack techniques that exploit “inherent vulnerabilities” in machine learning algorithm.

A doll to place your dreams on...

(1º§) "Someday I'm gonna be, exactly like you... till then... I'll make believe I'm you." So went the dulcet tones of Barbie's first ever TV advert in 1959. That year, what would come to be toy company Mattel's most significant and long-lasting creation, Barbie, arrived.

(2º§) She was the brainchild of Ruth Handler; the co-founder, along with her husband Eliot, of Mattel in 1945. According to one of two origin stories (the other involving an adult novelty doll called Bild Lilli, handed out at bachelor parties), Handler noticed her daughter Barbara playing with paper dolls and decided she wanted to give her a doll that was not a baby, but a woman she could aspire to. Barbie, named after her daughter, was born and she premiered at the annual Toy Fair in New York in March 1959. In the first year, 300,000 Barbie dolls were sold.

(3º§) She was 'petite' as the advert chimes, with all the latest clothes and accessories. Among these was, of course, a wedding dress. Her immediate MO was clearly as a stylish and sophisticated style maven, the kind of svelte, pretty woman young girls wanted to be − at least in 1959. Her first ever outfit − as exemplified in Gerwig's initial teaser trailer for the Barbie movie − was a black and white swimsuit, with white heels and white-rimmed sunglasses. Unsurprisingly, by 1961, she was 'going steady' with Ken (oddly named after the Handlers' son).

Courting controversy

(4º§) By the 1960s, Barbie was already attracting criticism for being a 'sex symbol'. To counteract this, the Handlers gave her a little sister, Skipper (originally a child and now sold as a teenager), and a best friend, Midge − who would go to have her own chequered history. Fashioned as a 'homelier' friend for Barbie (with red hair and freckles) Midge would disappear after 1967, returning in the 1980s along with a husband, kids and a 'Happy Family Line' of toys, which even included Pregnant Midge (with a detachable womb!). The line courted scandal from every angle − among which was outrage that Midge was pregnant without a wedding ring. Cannily, Gerwig has lined up Emerald Fennell to play Midge. Yes, Pregnant Midge.

(5º§) Though to many Barbie was too conventional − with her improbable proportions and origins as a doll who aspires to, essentially, marry Ken − to many she was too progressive. Indeed, as early as 1968, nine years after Barbie's invention, Mattel introduced their first Black doll, Christie, a friend of Barbie. Christie arrived at a fecund point in American politics, just as the Civil Rights Act of 1968 − enshrining the illegality of racial discrimination − was passed.

(6º§) It would not be until 1980, however, that Mattel would produce its first Black Barbie. She was designed by Kitty Black Perkins, who was then chief designer for Barbie. She bought her first Barbie doll aged 28, when interviewing for the position, when she was asked to create a whole new wardrobe for the doll. She was chief designer for more than 30 years and, in 1979, she was asked to design the first ever Black Barbie. When she arrived, she was wearing a red disco jumpsuit and came with the tagline: "She's Black! She's beautiful! She's dynamite!"

Text I The “literacy turn” in education: reexamining

what it means to be literate

In response to the phenomena of mass migration and the emergence of digital communications media that defined the last decade of the 20th century, the New London Group (NLG) called for a broader view of literacy and literacy teaching in its 1996 manifesto, A Pedagogy of Multiliteracies: Designing Social Futures. The group argued that literacy pedagogy in education must (1) reflect the increasing cultural and linguistic diversity of the contemporary globalized world, and (2) account for the new kinds of texts and textual engagement that have emerged in the wake of new information and multimedia technologies. In order to better capture the plurality of discourses, languages, and media, they proposed the term ‘multiliteracies’.

Within the NLG’s pedagogy of multiliteracies, language and other modes of communication are viewed as dynamic resources for meaning making that undergo constant changes in the dynamics of language use as learners attempt to achieve their own purposes. Within this broader view of literacy and literacy teaching, learners are no longer “users as decoders of language” but rather “designers of meaning.” Meaning is not viewed as something that resides in texts; rather, deriving meaning is considered an active and dynamic process in which learners combine and creatively apply both linguistic and other semiotic resources (e.g., visual, gesture, sound, etc.) with an awareness of “the sets of conventions connected with semiotic activity [...] in a given social space” (NLG, 1996, p. 74).

Grounded within the view that learning develops in social, cultural, and material contexts as a result of collaborative interactions, NLG argued that instantiating literacy-based teaching in classrooms calls on the complex integration and interaction of four pedagogical components that are neither hierarchical nor linear and can at times overlap: situated practice, overt instruction, critical framing, and transformed practice. […]

Although the NLG’s pedagogy of multiliteracies was conceived as a “statement of general principle” (1996, p. 89) for schools, the group’s call for educators to recognize the diversity and social situatedness of literacy has had a lasting impact on foreign language (FL) teaching and learning. The reception of the group’s work along with that of other scholars from critical pedagogy appeared at a time when the field was becoming less solidly anchored in theories of L2 acquisition and more interested in the social practice of FL education itself. In the section that follows, we describe the current state of FL literacy studies as it has developed in recent years, before finally turning to some very recent emerging trends that we are likely to see develop going forward.

INSTRUCTION: Read the following text to answer question.

The Key to Balanced Bilingualism

Bilingual education, especially in an immersion setting, is much more than just learning a second language: it’s a gateway to cultural and cognitive growth. As Vannina Boussouf – Assistant Head of School and Director of Primary at Lycée Français de New York (LFNY) – explains, several factors need to be considered to make sure this type of program succeeds, like the language environment of the country, the quality and amount of exposure to both languages, and the teaching expertise needed to guide students on their language journey.

One of the first things to think about in language immersion is the students’ language environment. In a country where the main language is different from the one taught in school, it’s important to make sure there’s enough exposure to the second language, and that it is high quality. This means more than just spending a lot of time speaking in the minority language (often the language of instruction in an immersion program); it also requires support to help students develop strong skills in both languages.

Language immersion relies on the idea that the more a child is exposed to a language, the better they will learn it. In this sense, combining varied interactions with stimulating learning environments is the key for students to truly grasp a second language.

One challenge teachers face is the “language insecurity” students can feel. When students are immersed in a classroom where the language spoken is different from what they use at home, they might feel uneasy. It is important to create a safe space where making mistakes is part of learning, and where students are encouraged. Thus, a positive learning environment helps not just with language learning but also with building thinking and cultural skills.

Besides, teachers need to be trained to spot when students feel insecure and respond with the rightstrategies, all while keeping the immersion experience engaging. This might include using visual aids, gestures, repetition, and interactive activities that help students participate, even if they’re still mastering the new language.

In reality, bilingual education through immersion is an ambitious goal, but when designed well, it offers great benefits to students. To make it work, it is necessary to consider the language environment, ensure high-quality exposure in both languages, and support students’ learning with care and expertise. Educators are responsible for creating spaces where both languages can thrive, while respecting the unique needs of each student. In addition, they can refine an approach where language immersion is balanced with support and excellence. In this bilingual journey, each student becomes an active participant in their own learning, opening doors to a multilingual, inclusive world.

Facebook deserted by millions of users in biggest markets

Facebook has lost millions of users per month in its biggest markets. In the last six months, Facebook has lost nearly 9m monthly visitors in the US and 2m in the UK. Studies suggest that its expansion in the US, UK and other major European countries has peaked. In the last month, the world's largest social network has lost 6m US visitors, a 4% fall, according to analysis firm Socialbakers. In the UK, 1.4m fewer users visited in March, a fali of 4.5%. Users are also turning off in Canada, Spain, France, Germany and Japan, where Facebook is extremely popular.

Alternative social networks have seen surges in popularity with younger people. Instagram, the photo-sharing site, got 30m new users in the 18 months before Facebook bought the business. Path, the mobile phone-based social network founded by former Facebook employee Dave Morin, which only allows its users to have 150 friends, is gaining 1m users a week.

Facebook is still growing fast in South America. Monthly visitors in Brazil were up to 6% in the last month to 70m, according to Socialbakers, whose Information is used by Facebook advertisers. India has seen a 4% rise to 64m - still only a fraction of the country's population, so there is room for more growth.

As Facebook itself has warned, the time spent on its pages from those sitting in front of personal computers is decreasing fast because people now prefer to use their smartphones and tablets. Although smartphone minutes have doubled in a year, to 69 a month, that growth may not compensate for dwindling desktop usage.

Facebook will tell investors about its performance for the quarter. Wall Street expects revenues of about $1.44bn, an increase from $1.06bn a year ago. Shareholders will want to know how fast the number of mobile Facebook users is growing, and whether advertising revenues are increasing at the same rate. Facebook founder Mark Zuckerberg has created a series of new initiatives designed to appeal to smartphone users. One initiative, Facebook Home, is software that can be downloaded onto Android phones to feed news and photos from friends - and advertising - directly to the owner's locked home screen.
