Fish Elevator Invented to Study Deep Sea Fish
We know more about the surface of mars than we do about the depths of our own ocean, but scientists from the California Academy of Science created an invention that allows researchers to bring never-before seen species from coral reefs in the deep sea to the ocean's surface. In the…
How are new robots helping with surgery?
Millions suffer from osteoarthritis, a condition that causes joints, especially knee and hip joints, to become stiff and painful. Luckily these joints can be replaced by an implant with usually good results. However, scientists are going one step further, bringing robots into the operating theatre to improve precision, and patient…
Active commutes may improve heart health
Any activity on your daily commute, like walking to the bus instead of just hopping in the car, might reduce your risk of cardiovascular disease, says a new study from the University of Cambridge, published in the journal Heart…
Kangaroo Care: the science of snuggles
We all love a good hug, whatever our age! Babies are no different. There's growing evidence that skin-to-skin contact is beneficial for babies, so Katie Haylor spoke with Laura Baird and Kelly Spike from Addenbrookes Hospital in Cambridge to find out what it's all about…
An update on Hawaii eruptions
Hawaii's Big Island has been experiencing a series of volcanic eruptions. What's causing them, and how is it likely to change in the future? To find out, Chris Smith talked to Jessica Johnson, a volcanologist at the University of East Anglia…
Could exercise at work be bad for you?
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…
Where is Earth's Freshwater Going?
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. To learn more Adam Murphy spoke with Matthew Rodell, from the NASA Goddard Space Flight Centre in Greenbelt, Maryland…
Understanding neurodegeneration mechanisms in disease
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…
Can birds cope with extreme spring weather?
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…
Tackling cancer in Tasmanian Devils
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…
Why are some people tastier to mosquitoes?
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…
Mice with Motorneurone Disease
Motorneurone Disease (MND), which is also known as ALS and Lou Gehrig's Disease, is caused by the death of the motor nerves that convey movement instructions from the nervous system to muscles. We don't understand why this happens, but up to 10% of cases appear to be genetic. Now Babraham…
Ivory, bear bile and tiger skins: Confiscated contraband
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…
Reprogramming skin cells to treat Multiple Sclerosis
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…
My whiskers! Faster stroke recovery in mice
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…
Is walking with friends better than walking alone?
Was exercising more one of your new year's resolutions? Has it ended up a broken promise at the bottom of your to-do list? Georgia Mills spoke to Catherine Meads from Anglia Ruskin University, who may be able to help.
New treatment for heavy periods
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…
Toothpaste ingredient fights malaria
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…
Find out about flu
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…
Tinnitus therapy trial success
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…
