It would be quite a superpower to regrow entire body parts. CrowdScience listener Kelly started pondering this after a discussion with her friend on whether human tongues could regrow. Finding out that they couldn't, she asked us to investigate the extent of human regenerative abilities.
Presenter Alex Lathbridge travels to Vienna, a hotbed of research in this area. He meets an animal with much better powers of regeneration than humans - the axolotl. In Elly Tanaka’s lab he finds out how she studies their incredible abilities – and shows off his new axolotl tattoo.
Why can these sweet-looking salamanders regrow entire limbs while we can’t even regrow our tongues? Palaeontologist Nadia Fröbisch has looked into the evolutionary origins of regeneration, and it goes a lot further back than you might think.
And in fact, even humans are constantly regenerating, by renewing the building blocks of our bodies: cells. New cells grow and replace old ones all the time – although, in some parts of the body, we do keep hold of the same cells throughout our lives.
However, cell turnover isn’t the same as regrowing entire organs or limbs. But can we grow new body parts in the lab instead? We meet Sasha Mendjan, who creates heart organoids using our cells’ innate ability to self-organise. How far off are we from implanting organs, grown from a patient’s stem cells, back into the human body?

Kamala Harris defends shifting positions as Donald Trump proposes free IVF treatment. Holiday travel headaches. Banning phones in school. CBS News Correspondent Cami McCormick has today's World News Roundup.
In her first major interview as the presidential nominee Kamala Harris was forward-looking while also defending Biden's policies. Donald Trump has been speaking in more moderate terms about reproductive rights. A deadly food-borne bacteria linked to deli meat has killed at least nine people a hospitalized dozens more.
Following anti-tourism protests across popular Spanish cities and towns, we are looking for the world's most unwelcome visitor. Our panellists (and producers) are pitching their terrible tourists to see who really is the worst of them all. Some of our contenders include...
The wild boars who's unanticipated vacay to Rome has gone on for so long and caused so much carnage that researchers are putting them on birth control.
The microbes potentially hitching a ride to the moon via space probes and astronauts' poo
The multi-destination parasite who wreaks havoc as it interrails through snails (castrating them on the way), frogs (making them spout multiple limbs) and birds.
But there are some instances when tourists can be a good thing - and this is especially the case in the human body when we want to grow a baby. How is in that we are able to protect what should be an 'unwelcome visitor' from a hyperalert, hostile immune system? Our expert Edward Chuong explains.
Plus, we uncover the DNA origins of the world's most popular coffee bean, hear the freeloading activities of the male angular fish, and read out a selection of your wonderful emails.

Today, we dive into Kamala Harris's interview with Dana Bash, the buzz around Doug Emhoff being declared a modern-day sex symbol, the situation with astronauts stranded in space, and Keith Lee's recent food reviews during his visit to D.C. Tune in!
In 2015, the hip-hop group Wu-Tang Clan released an album that was unlike any other in the history of recorded music.
It simultaneously set the record for the highest amount of money ever spent on a work of music, and it was the worst-selling album in history in terms of unit sales.
The reason why it holds both of those distinctions is because only one copy of it was ever made.
Learn more about Once Upon A Time in Shaolin and the album which is unlike any other ever made, on this episode of Everything Everywhere Daily.

Kamala Harris and Tim Walz sit down with CNN's Dana Bash for their much-hyped first big interview—and they pass the test. Donald Trump tries again to tack to the left on reproductive rights, and his campaign leans into their fight with Arlington National Cemetery over politicking at gravesites. Then, Jon and Dan go through the latest batch of national and state polls, all showing an extremely tight race.
