Lyme disease vaccine found to be safe and effective in clinical trial

×A vaccine against Lyme disease has been shown to be safe and effective in a clinical trial and could be available by 2025.Tens of thousands of people in the US and Europe are diagnosed each year with Lyme disease, which is transmitted by tick bites and can cause lifelong health problems like joint and nerve pain if it isn’t treated early.French company Valneva has developed a vaccine that works by stopping Lyme-causing bacteria in ticks from passing into people’s bloodstreams when the ticks bite. It does this …Existing subscribers, please with your email address to link your account...

Mould from Chernobyl nuclear reactor tested as radiation shield on ISS

Mould from Chernobyl nuclear reactor tested as radiation shield on ISS

×A radiation-absorbing fungus found at the destroyed has been shown to absorb harmful cosmic rays on the International Space Station, and could potentially be used to protect future Mars colonies.Exposure to cosmic rays poses a major health risk to astronauts leaving Earth’s protective atmosphere. Shields can be made out of stainless steel and other materials, but they must be shipped from Earth, which is difficult and costly.Xavier Gomez and Graham Shunk came up with the idea of growing radiation shields on Mars out of living organisms while …Existing subscribers, please with your email...

There might not be as many microplastic fibres in oceans as we feared

There might not be as many microplastic fibres in oceans as we feared

×Most of the microfibres polluting our oceans – which have long been assumed to be plastic – are actually natural fibres like cotton and wool. But we don’t yet know whether these fibres pose the same health risks to marine organisms.Textile microfibres are major contributors to marine pollution because they are readily shed from clothes during general wear and tear and laundering, and or wash down drains. A single machine wash of polyester clothing, for example, releases .Previous have tended to count all microfibres as plastic, based on the assumption that natural fibres like cotton and...

Pocket-sized device tests DNA in blood samples for genetic conditions

Pocket-sized device tests DNA in blood samples for genetic conditions

×It is now possible to use a cheap, lightweight and smartphone-powered detector to identify DNA in blood, urine and other samples, on the spot.At the moment, testing to identify DNA is usually done in laboratories using expensive, specialised equipment. To make this process faster and cheaper, Ming Chen at the Army Medical University in China and his colleagues developed a portable DNA detector made of 3D-printed parts that attach to a standard smartphone.The device can detect DNA based on characteristic mutations or short genetic sequences. It costs less than $10 to make, weighs just 60...

Grey hairs sometimes regain their colour when we feel less stressed

Grey hairs sometimes regain their colour when we feel less stressed

×People’s grey hairs sometimes naturally regain their original colour, typically when individuals feel less stressed. The finding suggests it may be possible to develop drugs to reverse greying.Lab mice go grey when stressed and the same thing seems to occur in people. It has long been assumed that once hairs turn grey, they stay that way. But Martin Picard at Columbia University in New York and his colleagues discovered by chance that hair greying sometimes naturally reverses.Existing subscribers, please with your email address to link your account access.Paid annually by Credit...
