Summary
A brain-computer interface allows a severely paralysed patient not only to move and use a robotic arm, but also to feel the sensations as the mechanical hand clasps objects . We hear from Jennifer Collinger at Pittsburgh University’s Rehab Neural Engineering Labs. And Nathan Copeland, who has been controlling the robotic arm with his thoughts via a series of brain implants.
Ralph Baric of the University of North Carolina tells us about the development of a multi-component vaccine that would be effective not just against the current coronavirus outbreak and its variants, but also future outbreaks from SARS-like coronaviruses that we don’t even know about yet.
Blood clots, thromboses, have been a problem for a small number of people following Covid vaccination Paul Knöbl, and a team of medics in Vienna have worked out the link between vaccination and clot development. They now have a method to treat such clots – so they should not be fatal.
And how did fungi and plants come to live together? Symbiotic relationships between the two are a key component of the evolution of life. Melanie Rich of the University of Toulouse has been looking at the present day genetic markers which allowed plants and fungi to help each other as they first colonised land millions of years ago.
Also...You are a star. Literally. You are a carbon-based life form and those atoms of carbon in the molecules that make up your cells were formed by a nuclear fusion reaction at the heart of long dead stars. That goes for the oxygen in your lungs too. And the red blood cells that carry that oxygen to your tissues? They contain haemoglobin, and nestled at the heart of each molecule is an element (iron) formed by a supernova - the fiery explosion at the death of a star. Your body is a walking, thinking museum of some of the most violent events in the universe.
This, as CrowdScience host Marnie Chesterton discovers, isn’t as special as it sounds. All of the stuff on the earth - the elements that make clouds and mountains and mobile phones – they all have an origin story. CrowdScience tells that story, starting with the big bang and ending with physicists, creating new elements in the lab. Find out the age of the elements and the distance they have travelled to make their current home on earth.

| 0:00.0 | In 2019, we began investigating the disappearance of Dr. Ruzha Ignatva. |
| 0:08.0 | I believe we are a very special network. |
| 0:10.0 | A scammer who stole billions from investors around the world. |
| 0:15.0 | She's on the FBI's 10 Most Wanted list. |
| 0:18.0 | And now, we have some unmissable updates. She has money and when you have |
| 0:23.0 | money you have power. Join me, Jamie Bartlett, as the hunt for the missing crypto queen continues. |
| 0:29.5 | Listen first on BBC Sounds. Thank you for downloading the Science Hour from the BBC World Service |
| 0:36.1 | with me, Roland Pease. |
| 0:38.2 | Well, later you can hear crowd science, the programme with hard answers to our listeners' difficult questions, |
| 0:44.9 | though sometimes those are more like poetry. |
| 0:48.5 | I like the idea that maybe my atoms are interstellar travellers, |
| 0:53.6 | and in a way, every part of me has |
| 0:57.6 | travelled across the universe. It makes the fact that I can't leave my flat a bit more bearable. |
| 1:04.1 | The intergalactic travels and infinite history of atoms squeezed into half an hour or so |
| 1:10.2 | of crowd science later in the podcast. |
| 1:12.9 | Before that, on science and action we've the treatment that should protect those very rare |
| 1:17.8 | individuals who have a bad reaction to the coronavirus vaccines. Also, news of a vaccine that |
| 1:24.2 | should avoid a future SARS-CoV-3 pandemic should such a virus ever emerge. |
| 1:30.3 | And the experiments that show how the very first land plants could have survived as they washed up onto a rocky shore from a primordial ocean. |
| 1:39.3 | The first connection between the plant and the fungi might not have been entirely beneficial for both of them. |
| 1:47.0 | It might have started as a predatory relationship where the fungus would try to eat the first land plants. |
| 1:54.0 | We start with a brain-computer interface that allows a severely paralyzed patient not only to move and use a robotic arm, |
