What exactly it means to be conscious has long been a question of profound debate amongst philosophers, and more recently, scientists. There are no easy answers, and it gets even trickier when you start asking whether animals are conscious: how can you find out about their subjective experience when they can’t tell you about it?

Never afraid to tackle the impossible, CrowdScience is looking for answers after listener Natalie got in touch. She has lived with her cat for years and has a strong sense that he has thoughts and feelings: he has his own personality, acts in complex ways, and even has ‘grumpy days’. But is this consciousness? Is there any way of scientifically testing for it? How different from our own inner world is that of a cat, an octopus, or a bumblebee? And if we can find any answers to these puzzling questions, how does that affect the way we treat animals - not just our pets, but all the animals we share our planet with?

We meet Natalie and her cat, and discover how scientists have explored the minds of pigs, cows and cuttlefish. Helping us ponder the elusive question of animal consciousness are philosopher Peter Godfrey-Smith, neuroscientist Anil Seth, animal welfare expert Donald Broom, ethicist Jessica Pierce, and comparative psychologist Alex Schnell.

Featuring David Seddon as the voice of Chicco the Cat.

Encore episode. Researchers discovered that this simple instrument could offer insights into the evolution of human speech. Short Wave reporter Emily Kwong talks with primatologist Adriano Lameira about a growing body of evidence that humans may not be the only great apes with voice control.

Read the paper he published last year.

A multi arm trial testing a range of drugs has shown that readily available steroids can be lifesaving for people severely ill with Covid-19. Max Parmar, head of the UK Medical Research Council’s clinical trials unit says the trial design, where many potential drugs can be tested against the same controls, is key to producing results quickly.

As it spreads around the world SARS-CoV-2 is mutating. But what does this mean? These mutations are part of a natural process and some researchers are finding they make no real difference to patient outcomes so far, but others are concerned the virus may become more dangerous. Neville Sanjana from New York University has been running lab tests on the mutant virus.

Measles mutated from an animal virus, developing the ability to jump from cattle to human around 2,500 years ago. Sebastien Calvignac-Spencer from Germany’s Robert Koch Institute tracked its origins using preserved lung samples from centuries old measles victims.

Covid -19 has become a magnet for conspiracy theorists. A common unfounded claim is that the virus was deliberately manufactured. During the boredom of lockdown such ideas have taken off online, with conspiracy videos receiving millions of views. We speak to scientists who have been targeted, and become the subject of this online misinformation.

Marine biologist Ayana Elizabeth Johnson wrote a Washington Post op-ed about the ways the fight around climate change and racial justice go hand in hand. Host Maddie Sofia talks with her about that and how Ayana says the fight against climate change could be stronger if people of color weren't being constantly exhausted by racism.

It's called asymptomatic spread. Recently a scientist with the World Health Organization created confusion when she seemed to suggest it was "very rare." It's not, as the WHO attempted to clarify.

NPR science reporter Pien Huang explains what scientists know about asymptomatic spread, and what might have caused the WHO's mixed messages.

Does getting the coronavirus once make you immune to it or could you get it again? Many are looking to antibody tests for answers. The logic is: if I have antibodies for the coronavirus, I must be immune.

Well, turns out ... it's complicated, as Katherine Wu writes for the Smithsonian Magazine. We invited her onto the show to explain.

A federal court recently ordered farmers to stop spraying one of the country's most widely used herbicides, dicamba. NPR's food and agriculture correspondent Dan Charles tells us the ruling has turned the world of Midwestern agriculture upside down. Then the Environmental Protection Agency came out with its own order.

Despite the Covid-19 pandemic efforts to counter massive swarms of locusts across East Africa have continued. In many places this has been very effective, killing up to 90% of locusts. However, the threat of repeated waves of locusts remains says Cyril Ferrand, who leads the UN Food and Agriculture Organisation's Resilience Team in East Africa.

Conversely West Africa is unaffected by locusts and with a block on imports local producers have seen demand grow for their produce, an unusual positive effect from the pandemic according to Sandrine Dury from the French agricultural research agency CIRAD.

We examine the potential for a second wave of coronavirus as many countries relax lockdown measures, businesses reopen and mass protests take to the streets. Epidemiologist Carl Bergstrom is interested in working out which of these movements is likely to have the most impact.

And from South Africa, how radio telescope engineers there have turned their hands to developing new ventilators appropriate for regional needs.

And we were bowled over by a question from one CrowdScience listener in Australia wants to know how likely it is that the atoms in his body have been used in someone else’s body? We all like to think we are unique; no one is quite like us. But is that really true?

Presenter Marnie Chesterton tackles Moshe’s question with help from every area of science. From geologists helping us work out how many atoms are on the Earth’s surface to biologists helping us work out how many atoms each body uses. Perhaps we are much less special than we think.

That's what they call themselves: long-haulers. They've been sick for months. Many have never had a positive test. Doctors cannot explain their illness any other way, and can only guess at why the virus appears to be with them for so long.

Ed Yong of The Atlantic explains what might be going on, and why their experience mirrors that of other sufferers with chronic illnesses who battle to be believed. We also spoke with Hannah Davis, a long-hauler from New York City.

Read Ed's story on long-haulers here.
