'Zombie spider' fungi among Kew archive specimens
"Zombie spiders" and Darwin's HMS Beagle collection are among the fungi being digitally archived by scientists at the Royal Botanic Gardens, Kew.Kew's Fungarium, an archive beneath the west London garden, is one of the world's biggest and most important collections of fungal diversity.It contains more than a million specimens collected over the past 175 years.Teams have been creating high resolution images, transcribing the data and uploading it onto Kew's portal, which grants researchers worldwide remote access to the collection.
Operations manager of the Fungarium digitisation, Shaheenara Chowdhury, said fungi "have been overlooked by the scientific community for so long, and yet they are amongst the most wonderful and mysterious organisms on the planet".The specimens are georeferenced and span decades, meaning experts can observe how a species' range has changed over time, helping to inform conservation plans.Kew scientists have also been tapping into the genetic information stored in the Fungarium's 50,000 type specimens.The project, which is a partnership with the National History Museum and is backed by government funding, aims to sequence about 7,000 of these fungi, making the data publicly available online in the coming years.The hope is that this will accelerate the discovery of new chemicals and medicines.Scientists estimate there are 2.5 million fungal species in the world but only 166,000 have been described.
Among the species digitised by the Kew team is Gibellula attenboroughii - or David Attenborough's "zombie fungus" - named after first being spotted on an episode of BBC's Winterwatch in 2021, having infected an orb-weaving cave spider.The parasitic fungus species belongs to a group that infects their invertebrate hosts and takes control before killing them as part of their spore-spreading mechanisms.Another was Cyttaria dawinii, a small globular parasitic fungus collected by Charles Darwin in the Tierra del Fuego archipelago in South America during the HMS Beagle voyage between 1831 and 1836.

One of NHS's biggest AI projects is halted after fears it used health data of 57 MILLION people without proper permissions
NHS England has paused a ground-breaking AI project designed to predict an individual's risk of health conditions after concerns were raised data from 57 million people was being used without the right permissions. Foresight, which uses Meta 's open-source AI model, Llama 2, was being tested by researchers at University College London and King's College London as part of a national pilot scheme exploring how AI could be used to tailor healthcare plans for patients based on their medical history. But the brakes were applied to the pioneering scheme after experts warned even anonymised records could contain enough information to identify individuals, The Observer reported. A joint IT committee between the British Medical Association (BMA) and the Royal College of General Practitioners (RCGP) also said it they had not been made aware that data collected for research into Covid was now being used to train the AI model. The bodies have also accused the research consortium, led by Health Data Research UK, of failing to consult an advisory body of doctors before feeding the health data of tens of millions of patients into Foresight. Both BMA and RGCP have asked NHS England to refer itself to the Information Commissioner over the matter. Professor Kamila Hawthorne, chair of RGCP, said the issue was one of 'fostering patient trust' that their data was not being used 'beyond what they've given permission for.' She said: 'As data controllers, GPs take the management of their patients' medical data very seriously, and we want to be sure data isn't being used beyond its scope, in this case to train an AI programme. 'We have raised our concerns with NHS England, through the Joint GP IT Committee, and the committee has called for a pause on data processing in this way while further investigation takes place, and for NHS England to refer itself to the Information Commissioner. 'Patients need to be able to trust their personal medical data is not being used beyond what they've given permission for, and that GPs and the NHS will protect their right to data privacy. 'If we can't foster this patient trust, then any advancements made in AI – which has potential to benefit patient care and alleviate GP workload – will be undermined. 'We hope to hear more from NHS England in due course, providing definitive and transparent answers to inform our next steps.' Katie Bramall, BMA England GP committee chair, said: 'For GPs, our focus is always on maintaining our patients' trust in how their confidential data is handled. 'We were not aware that GP data, collected for Covid-19 research, was being used to train an AI model, Foresight. 'As such, we are unclear as to whether the correct processes were followed to ensure that data was shared in line with patients' expectations and established governance processes. 'We have raised our concerns with NHS England through the joint GP IT committee and appreciate their verbal commitment to improve on these processes going forward. 'The committee has asked NHS England to refer itself to the Information Commissioner so the full circumstances can be understood, and to pause ongoing processing of data in this model, as a precaution, while the facts can be established.' 'Patients shouldn't have to worry that what they tell their GP will get fed to AI models without the full range of safeguards in place to dictate how that data is shared.' An NHS spokesperson confirmed that development of the Foresight model had been paused for the time being.

Not only does sleep recharge your batteries - it might also stop you going deaf in your old age
Catching up on your sleep at the weekend could do much more than just recharge your batteries - it might also stop you going deaf in your old age. A new study involving nearly 7,000 people found those in their 40s and 50s who stayed in bed for an extra hour or so at the weekend were 40 per cent less likely to suffer age-related hearing loss when they got older. One in three adults in the UK are deaf, have hearing loss or suffer with tinnitus – a ringing in the ears, according to the Royal National Institute For Deaf People (RNID). This rises to one in two in those aged 55 or over and by the time they reach their seventies, around 80 per cent of people will be struggling to hear properly. Age-related hearing loss is a major risk factor for dementia, loneliness and social isolation. Experts at Chungnam National University in South Korea studied the sleeping habits of 6,797 men and women aged over 40 and recorded how many were also showing signs of partial or complete deafness due to the ageing process. The results, in the journal Annals of Epidemiology, showed those enjoying regular weekend lie-ins were 42 per cent less likely to suffer mild hearing loss and 21 per cent less likely to have moderate loss. Those in their 40s and 50s seemed to benefit the most. But lie-ins did little to preserve the hearing of those over 65. Scientists said they think an extra hour or so of rest may preserve nerve connections in the brain that are vital for good hearing. Lack of proper sleep is known to cause inflammation which can damage the cochlea – the snail-shaped structure inside the ear that turns sounds into electrical signals for the brain. Previous studies have found snoozing at the weekend can also protect against heart disease and slash the risk of dementia by up to 70 per cent, especially in those who do not get enough sleep during the week. The researchers said: 'Our study suggests the association between weekend catch-up sleep and hearing loss may be more pronounced among middle-aged adults – those who are 40 to 64 – compared to adults aged 65 or older.'

Liver disease is on the rise in the UK due to soaring obesity levels, but a 10-minute stroll each day can help stop it in its tracks
Walking for just ten minutes a day can cut the risk of developing fatty liver disease, which affects up to one in three adults. The build-up of dangerous fat in the organ is usually triggered by an unhealthy diet and sedentary lifestyle. Rates of the disease – which can significantly increase the risk of liver cancer – have risen in the UK due to soaring obesity levels. In a new study, scientists from the University of Oxford followed more than 91,000 people to see if daily activity levels were related to their chances of fat accumulating in the liver. Volunteers wore a wrist device for seven days to measure the number of steps they took. The study, published in the journal Medicine and Science in Sports and Exercise, showed the more they walked, the less likely they were to develop the potentially fatal condition. For every 1,000 steps – or approximately 10 minutes of movement – the chances of getting fatty liver dropped by around 12 per cent, researchers found. Although it's common, non-alcoholic fatty liver disease can be hard to detect, as there are few external signs of it and no obvious symptoms during the early stages. A healthy liver should contain no fat at all and most people with the condition have no idea they are affected. While it's linked to obesity, some sufferers can be slim but with hidden fat deposits in and around the liver. Previous studies have found the disease can be stopped in its tracks by losing around 10 per cent of body weight.
