Naked Scientists Special Editions, iTunesU ·

2018/05/17

Exercise is good for us, it's one of the best things you can do to keep your mind and body healthy for a long age. But perhaps not all exercise is equal. A new analysis out in the British Journal of Sports Medecine reports that exercise at work is associated with an increased risk of early death in men. So what's going on? Georgia Mills spoke to study author Pieter Coenen, of VU University in Amsterdam.

Knowing where Earth's freshwater is accumulating, or perhaps more critically, disappearing is of paramount importance. A new study in Nature has analysed changes in freshwater across the entire planet.

2018/05/03

Neurodegeneration is a process involved in several serious and debilitating diseases, for which there is often no cure. One of the first steps on the journey towards a treatment to stop neurons dying is understanding how and why they do so. Now, scientists from Cambridge University and the University of Toronto have announced a mechanism that explains how neurons die in two diseases, motor neurone disease and a type of dementia called fronto-temporal dementia. Georgia Mills spoke to Cambridge

2018/05/02

Are you struggling to know what to wear for the weather at the moment? One day in the UK it's freezing, the next rain, the next a veritable heat wave. Apart from playing havoc with BBQ plans, this extreme variation in weather is also affecting local wildlife. Georgia Mills went for a stroll along the river Cam with the RSPB's Richard Bradbury to find out more.

18.04.27 - Tackling cancer in Tasmanian Devils

Naked Scientists Special Editions, iTunesU ·

2018/04/26

Tasmanian devils are black, carnivorous, scavenger marsupials that live - perhaps unsurprisingly, on the island of Tasmania. In recent years an intriguing type of cancer has been decimating their numbers, pushing the animals to the brink of extinction. Known as "Devil Facial Tumour Disease" - or DFTD - the cancer is spread when an affected animal bites - and literally implants - some of the tumour from its own mouth into the face of another devil. The tumours avoid detection by the immune system by

18.04.23 - Why are some people tastier to mosquitoes?

Naked Scientists Special Editions, iTunesU ·

2018/04/22

Every year millions of people contract malaria, which is a blood parasite infection spread by mosquitoes. And part of the reason why the infection spreads so successfully, scientists now know, is because the parasite makes an infected human over-produce certain skin odours that are irresistible to a mosquito. Chris Smith spoke to Ailie Robinson, researcher at the London School of Hygiene and Tropical Medicine and the lead author on the new study that's uncovered how this happens

18.03.20 - A new model for motor neurone disease

Naked Scientists Special Editions, iTunesU ·

2018/03/20

Motor neurone disease (MND) is a degenerative disease affecting around 5,000 people in the UK. It attacks people's ability to move, speak and breath, and usually is fatal within two years. At the moment there is no cure, but scientists are trying to find out more about what causes MND and how we might one day treat it. This week, a paper out in Nature Neuroscience describes a new model for MND, which has revealed some unexpected clues about how the disease operates, and may even lead to a target for

When people take wildlife products over a border that is under the control of CITES. Some of it is illegal, and this is when Border Force step in, confiscating the items in question and when possible, returning them to the wild. But what do people bring through? Georgia Mills was shown the Dead Shed, by senior Border Force officer Grant Miller, a horrific stash of animal and plant products that had been confiscated at Heathrow Airport. This content may be upsetting to some people.

2018/02/26

Multiple Sclerosis, or MS, affects hundreds of thousands of people. It's a condition where the body's own immune system attacks a protective layer around nerve fibres called myelin. This prevents messages being conveyed quickly and faithfully through the brain producing symptoms that can include difficulty with vision, movement, speech, balance and sensation. In recent years scientists have begun to explore the use of stem cells to combat the progression of the disease. As author Stefano Pluchino,

18.02.07 - My whiskers! Faster stroke recovery in mice

Naked Scientists Special Editions, iTunesU ·

2018/02/07

Scientists in the US have uncovered a surprising potential treatment for strokes: short-term sensory deprivation. Strokes occur when the blood supply to the brain is interrupted; this destroys the affected nerve cells, and robs the victim of the function of the affected brain area. But it is possible to achieve some degree of recovery by encouraging other, adjacent healthy parts of the brain to rewire themselves and take over from the damaged area. Working with mice, Washington University

Naked Scientists Special Editions, iTunesU ·

2018/01/29

Up to a third of women experience debilitatingly heavy periods. This can cause significant disruption. It can also lead to depression; time off work; and, in severe cases, even lead to a low blood count or anaemia. Currently, heavy periods are treated hormonally or surgically, but these options have side effects and can affect fertility. So is there a better treatment? Edinburgh University's Jackie Maybin thinks so.

18.01.22 - Toothpaste ingredient fights malaria

Naked Scientists Special Editions, iTunesU ·

2018/01/22

Scientists have shown that a toothpaste ingredient could be used as an anti-malarial drug. Spread by mosquitoes, malaria is caused by Plasmodium parasites, and kills over half a million people every year, 70% of them children. In recent years the parasite has also become resistant to most of the existing anti-malarial compounds. This new discovery, by researchers at the University of Cambridge, was aided by Eve, an artificially-intelligent 'robot scientist'. Chris Smith was joined by Steve Oliver

2018/01/18

It's winter time again in the northern hemisphere and the influenza virus - the 'flu - is making its seasonal rounds. The virus infects millions of people every year, and vulnerable individuals with underlying health complaints including heart disease, kidney problems and diabetes, as well as pregnant women, the very young and the over 65s are at higher risk of developing a severe infection.

2018/01/10

Around one in ten people have to live with tinnitus, this is a persistent noise ringing in the head when there's nothing external causing it. The severity of tinnitus can range from irritating to completely life-changing, by making it nearly impossible to work or sleep, and there is no cure. But now, scientists have come up with a way to reduce the severity of symptoms, by stimulating parts of the brain responsible for causing the phantom sounds.

2017/12/21

The question of where life began is a difficult one to answer. While many scientists believe that life began on earth, others believe that life, or at least its building blocks, first formed in space. A recent study from the University of Sherbrooke, in Canada, has shown how complex organic molecules could form on icy comets - from nothing more than simple molecules and radiation. And it's possible that this could explain how complex molecules like amino acids - which are the building blocks of

In the run up to Christmas, shops are bursting at the seams with delicious treats, appealing platters and indulgent morsals, which can make sticking to a healthy diet rather unlikely. And food consumption has consequences for our "waist" in more ways than one! According to the Food and Agricultural Organisation of the UN, over a third of all the food made globally each year goes un-used, that's around 1.3 billion tonnes. But could adhering to a healthier diet in the food we do eat make a difference
