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's intended pacing, mood and tone. However, while some artists like them and others less so, it seems they are here to stay.

The Future of Global Economy and Society

Characters:

Emma: A professor of International Relations.

John: A journalist specializing in global economics.

Sophia: An environmental activist and policy advisor.

Emma: Good afternoon, everyone. Today, I'd like to delve into the intricacies of the global economy and its impact on society. As we navigate through these unprecedented times, what do you think are the key drivers reshaping our world?

John: From my perspective, the most significant factor is the acceleration of technological innovation. The digital economy is not just expanding; it's revolutionizing traditional sectors. Artificial Intelligence, blockchain technology, and the Internet of Things are all converging, creating a paradigm shift in how we understand and conduct business.

Sophia: I agree, John. However, I would argue that while technological advancement is transformative, it also presents ethical dilemmas. The digital divide is growing, and the disparity between those who have access to these technologies and those who don't is becoming a critical issue. Moreover, the implications for data privacy and surveillance are profound and cannot be overlooked.

Emma: That's an excellent point, Sophia. The ethical implications are vast. But moving beyond technology, how do you see geopolitical tensions influencing global economic stability?

John: Geopolitical tensions have always played a pivotal role. However, with the recent rise of protectionist policies and trade wars, we are witnessing a fragmentation of the global economic order. Countries are increasingly prioritizing national interests, which could lead to a significant realignment of global alliances and trade networks.

Sophia: And this realignment is not without consequences. We must consider the environmental impact as well. The current economic model, heavily reliant on fossil fuels, is unsustainable. We need a radical transition towards a green economy, and that requires international cooperation—something that's hard to achieve amid rising nationalism.

Emma: Absolutely. The concept of a green economy is gaining traction, but there's a lot of skepticism about its feasibility, especially in developing countries where economic growth is still heavily dependent on traditional industries. What are your thoughts on this?

John: It's indeed a delicate balancing act. Developing nations argue that stringent environmental regulations could stifle their economic growth and exacerbate poverty. On the other hand, the consequences of inaction could be catastrophic, not just for these countries, but globally. Perhaps the solution lies in creating financial incentives for sustainable development.

Sophia: That's where policy-making becomes crucial. We need to implement more robust frameworks for international cooperation that include financial support, technology transfer, and capacity building. The global north has a historical responsibility to assist the global south in this transition.

Emma: These are compelling insights. It's clear that the path forward is complex and requires a multifaceted approach. Balancing technological, economic, environmental, and ethical considerations is a formidable challenge. However, it's also an opportunity for us to redefine the future of global society.

John: I couldn't agree more, Emma. The question is not whether we will face these challenges, but how we will respond to them collectively.

Sophia: Exactly. It's not just about adapting to change but about proactively shaping it. We must engage in more dialogue, foster innovation, and, above all, uphold our shared values of equity, justice, and sustainability.

Emma: Well said, Sophia. I believe our discussion today has highlighted the interconnectedness of these issues and the importance of global solidarity. Thank you both for this enlightening conversation.

John and Sophia: Thank you, Emma.

Cancer therapies are getting a makeover

By Vanessa Chalmers, Health Features Editor

Cancer is no longer a death sentence when diagnosed, thanks to the ongoing emergence of treatments that can extend lives as well as better detection methods to find the disease earlier.Scientists have learned a lot about the immune response to cancer and are now harnessing it.When we hear the word vaccine, we typically think of it as preventing disease.But in this case, vaccines are being used as a treatment. Once injected they train the immune system to recognise and fight cancer cells. The body itself is recruited to kill the cancer, rather than relying on medicines.The process leaves healthy cells untouched, unlike chemotherapy, which kills healthy tissue and causes debilitating symptoms. NHS England's national cancer director, Dame Cally Palmer, said cancer vaccines being trialled could mark a huge step in treating the disease.There are also personalised vaccines which are designed specifically for an individuals cancer, based on their genetics.The challenges with personalised vaccines and other hugely advanced cancer therapies is they are very expensive to develop - and the question is whether the NHS will be able to afford such therapies when they come to fruition.
