Apopo is a charity that trains African giant pouched rats for humanitarian purposes, with a view to combating some of the challenges faced by countries in the developing world. Originally, they trained these much shunned rodents to sniff out unexploded landmines left over from wars in countries like Mozambique. More recently, their keen sense of smell has also enabled trainers to develop them into excellent detectors of Tuberculosis carriers, so that patients can get diagnosed more quickly than before and receive treatment. Now, these Hero rats as they've been dubbed, are being prepared for a... Like this podcast? Please help us by supporting the Naked Scientists

Did you end up in your dream job? Or did you end up pursuing a career quite intensely for some reason that eludes you? Perhaps the media representation of your profession had a part to play. Shrikanth Narayanan and colleagues from the University of Southern California created a dataset to analyse 4000 professions in the subtitles of over 136,000 movies and TV shows and found that their representation may have influenced some of us to take up a career we loved watching on screen...

Now, I want you to cast your mind back to that first lockdown (if you can bear it) and to think about the ways you chose to fill all that new found free time. Perhaps, like the participants of a survey conducted by the Paris Brain Institute to learn more about the effects of the pandemic on creativity, you decided to sharpen your culinary skills, or spent more time pottering in the garden.

Dingoes are native Australian dogs, although how and when they got to Australia isn't known. They were certainly already there by the time the first western explorers visited the continent, but fossil dingo remains go back only a few thousand years. So what is the relationship between dogs and dingoes, and the wolves they're both related to?

If I asked you to give up one of your five senses, which one would you choose? Chances are, instead of giving up your ability to see or hear, your sense of smell would be in pole position for the chop.

The world has a huge problem with plastics. While they are a materials scientist's dream in terms of their properties, they are an environmentalist's worst nightmare, because they don't break down naturally and are very hard to recycle.

Researchers have been studying DNA as a method to store binary data. As data generation continues to increase in the information age, we need new methods to store it. DNA is extremely robust and can store data 100 times more densely compared to a computer hard drive. In order to capitalise on DNA as a data storage platform, modifications to the molecules that make up DNA are currently being studied. Like this podcast?

There's a growing body of evidence that birds can detect magnetic fields like the one around the Earth, possibly by "seeing" them. And this, researchers think, accounts for how migrating birds, like reed warblers, manage to find their way, seemingly unerringly, half way around the planet. But it's more subtle than just using the magnetic field like a compass. What Oxford University's Joe Wynn thinks is happening is that the birds are pre-programmed by their upbringing to fly in a certain direction, but they use the angle - or inclination - of the Earth's field, to work out how far north or...

Greenfield housing developments are residential communities built upon land which was not previously occupied by anything else. These modern homes are often very energy efficient, but a new report by Transport for New Homes has found that these developments are offsetting their positive contribution to reducing greenhouse gas emissions because of a lack of planning around sustainable modes of transport.

Tropical rainforests are deforested at an alarming rate to make way for cultivating crops and rearing livestock. But what happens when these forest areas are abandoned and left to recover in their natural way?

Changing the way the brain controls how we sleep, as a new study suggests, might be a way to cut the risk of Alzheimer's Disease. Alzheimer's is the commonest form of a group of conditions known as senile dementia. They occur when brain cells are lost, progressively robbing us of our mental faculties. In Alzheimer's Disease it's caused by a buildup of a toxic chemical called a-beta; also known as beta amyloid. This naturally accumulates during the day and gets flushed out during a restful night's sleep. But, by studying mice that have been genetically programmed to develop a form of... Like this podcast?

Understanding the human brain and how it completes complex tasks, like processing other people's speech as well as producing its own, is a complex task in and of itself. As it stands, neuroscience isn't able to tell us the underlying computations that lead to human language. New research from the US has taken an interesting approach to working this out: instead of just studying how real, human intelligence deals with language, these researchers have been looking at how artificial intelligence does it too.

Astronomers believe that nearly every galaxy has a supermassive black hole at its centre, this being true for our very own Milky Way. These objects exert such strong gravitational forces on the matter contained within them that it cannot escape the black hole's pull. Scientists using the LOFAR telescope in the Netherlands have been studying the impact that such black holes have on the Universe on a mind-bogglingly large scale.

During IVF or in-vitro fertilisation, sperm and eggs are mixed together in a dish to produce fertilised embryos, one or two of which are placed in the uterus where the hope is they will trigger a successful pregnancy. Previously, embryologists would pick out and use only what they judged to be the most promising looking embryos. But now new research from the reproductive genetics company, Igenomix, has found that a large proportion of embryos that were previously being overlooked can in fact lead to successful pregnancies.

2021 marks 100 years since insulin was first discovered. The World Health Organisation estimates that 422 million people around the world have diabetes, a disease where the body either can't produce enough insulin or doesn't respond properly to insulin. In the UK, 1 in 15 people are affected, and that's only set to rise as more and more of us are overweight or obese.

More than 50% of the world's population now lives in urban areas and, in recent years, many major cities have been hit with extreme weather events due to the effects of climate change, like the flooding that hit the London underground - and Queen guitarist Brian May's basement - in the summer of 2021. A key reason for this might be that the urban environments themselves are exacerbating the heating effect, as Verner Viisainen heard from Iain Campbell, from the organisation RMI and the lead author of a new United Nations guide on cooling down cities...

Cities have been found to be warming at faster rates than the rest of the planet due to the materials used such as concrete absorbing heat more readily than organic materials.
