Hei, tässä on Alice. Nyt on aika Unexpected Elements-kysymykseen. Kondomit voivat osallistua suuremman roolin yhteiskunnalliseen terveydenhuoltoon, jolla voidaan vahvistaa ulkoilmoituksia ja seksuaalisia infektioita. Yhteiskunnallisen terveydenhuoltojen mukaan kondomit ovat käyttäneet 117 miljoonia uusia HIV-infektioita vuonna 1990.

Researches have been experimenting with mixing latex with other materials to make condoms stronger, thinner and a bit more comfortable. So this week I want to know what material have scientists not added to latex condoms? A. Grass, B. Graphene or C. Gelatine. Again, what material have scientists not added to condoms? A. Grass, B. Graphene or C. Gelatine.

Tarkoita sitä, ja olen takaisin vastauksessa vastauksessa.

You're listening to Unexpected Elements from the BBC World Service, where disruptions to global supply chains caused by the blockade of the Strait of Hormuz has led to the world's biggest manufacturer of condoms saying they might need to raise prices. So far we've talked about latex mishaps and koala contraception, but we couldn't talk about condoms without talking about male contraceptive pills.

Good morning. Where's the male pill, John?

One of the unique things about sperm is they swim. Very clever chemists can develop inhibitors of those functions. And that's been tested to a degree in animal models, but not in humans to my knowledge. So you've got these three different approaches. You've got blocking the sperm from getting out. You've got blocking the sperm from being produced. And then you've got blocking the sperm from being able to swim anywhere once they are produced. Have you got a frontrunner?

Kyllä, se on todella kiva. Kuuntelit Fase 2b-klinikkojen kohdalla, ja kysyn, onko se seuraava, jonka olemme saaneet klinikkojen kohdalla ihmisten kanssa, ja mikä on pysähtynyt klinikkojen kohdalla aiemmin?

So, who would have thought that the blocking of the Straits of Hormuz would have led to a conversation about whatever happened to the male contraceptive? We've got here thanks to the rise in the price of condoms, which is an unexpected consequence of the oil needed to produce this latex-based product.

Still to come on the show. Birds do it. Bees do it. Eels? We're not so sure. Until now, we hear how Chinese scientists have finally managed to make eels breed in captivity. Stay with us.

This is Unexpected Elements from the BBC World Service, the show that looks for the science behind the headline. And this week we've been inspired by the rising price of condoms caused by the closure of the Strait of Hormuz. I'm Marni Chesterton in Cardiff in the UK and I'm here with... Leonie Gibé, who is going feral on the wild coast in South Africa. And... Sandy Ong in Singapore, much less exciting.

Yes, the opposite of feral. I think that's what Singapore is to me.

So each week we wade our way through a lot of papers and press releases, different stories, trying to bring you the best of the science behind the news. And sometimes we come across something that's slipped under the radar that deserves a little bit more attention. And so this is the place where we make space for it to shine in the spotlight. Sandy, what are you bringing to our show and tell section?

I was doing a bit of digging around and I came across a bit of research that I think you might find interesting. So it's from a team at China's Jimei University who announced earlier this month that they have found a new way to breed Japanese eels artificially. I should say to listeners who aren't regular that what happens here is I normally award bonus points if the under the radar story relates to the overall theme. Now I can see a breeding link straight away, but can you, Sandy, link this to condoms too in some way?

Kyllä minä voin. Marni, tämän viikon ajan voin voittaa kaikki sinun Sperrys-bonus-paikkoja. Jouluaikaisesti elokuvat olivat käyttäneet aiemmissa aikoissaan, erityisesti medievalin aikoissa. He olivat tunneet olevansa erittäin hyviä ja toimivat hyvällä rajoittamalla. Hyvä. Okei.

I guess you use what you've got. I'm also really excited to hear more. I love eels. I think we should take a moment to go into the seriously complex, bizarre life cycle for most eels. So when you think of long distance migrations within the animal kingdom, what usually comes to my mind are birds flying thousands of kilometers to their wintering grounds and back, salmon swimming upstream, wildebeest crossing vast plains in Africa and so on.

Mutta asia, jota minä en ajattele, ja toivon, että useimmat eilijät eivät ole, ovat kylmät. Mutta nämä kylmät ovat todennäköisiä kylmiä. He ovat tunnettu tekemään epäkirjoituksia toisista kylmiistä. Kun puhutaan japanilaisista kylmiistä, he olivat syntyneet Mariana-alueella Pacific Oceanin länsimaissa. Siitä jälkeen he kylmättivät maailmanlaajuisesti noin 3000 kilometriä.

jatkuvasti saavuttamaan rauhallisia rikkoja ja lakioita Etelä-Aasassa. Japanissa, Taiwanissa, Kiinassa ja Koreassa on se, mitä me puhutaan. He elävät siellä noin 15-20 vuotta, kun he ovat valmiita saavuttamaan rikkoja. Se on silloin, kun he aloittavat saavuttamaan rikkoja ulos maailmalle, johon he olivat syntyneet. Rikot vain saavat rikkoja melko rauhassa, eli vain muutama kuukausi, yleensä loppuun tai keskuudessa. Ne ovat yleensä liittyneet uudelleen maailmaan.

For instance, researchers only managed to pinpoint that Japanese eels spawned in the Mariana Ridge about 15 years ago. It was even more recently, in 2022, that researchers succeeded in using satellite tags to track European eels, which are a cousin of the Japanese eel.
