Opening our eyes to the science of sleep, in 1971
'Sleep is like love. If you have it, you take it for granted,' reports Wendy Cooper in the Observer Magazine on 24 January 1971. If you don't, it's rhythmic rocking or counting sheep for you, though not for Charles Dickens: he made sure his bed faced north, better to boost his creativity as he slumbered.
We spend a third of our lives sleeping, but some feel they still don't get enough, some (narcoleptics) fall asleep when they eat. Some sleepwalk or, in one case, sleepride their motorbike in the middle of the night.
Insomnia, one of the most common complaints to doctors, sees pharmaceutical companies researching 'new sleep-inducing drugs'. In special sleep laboratories throughout the world, the 'secrets of the strange phenomenon of sleep are being properly investigated for the first time,' enthuses Cooper. They are armed with a new wonder machine: the electro-encephalograph (EEG), which detects the minute electrical changes taking place in the brain, amplifying and recording them.
Researchers in the control room watch their sleeping volunteers, and the charts. The real excitement starts, says Cooper, when 'the eyes make rapid jerky coordinated movements… This indicates a special form of sleep known as rapid eye movement or REM sleep; the brainwaves at these times resemble waking brainwaves and the body parallels this with a storm of activity'. Irregular heart-rate, increased oxygen intake, reduced muscle tone, It's all preparation for action in the sleeper's 'personal world of dreams', dreams that are vivid, 'emotional, self-involved and often bizarre adventures'.
This association between REM sleep and active dreaming is 'perhaps the most exciting discovery so far made in sleep research' – for 'it makes possible the scientific study of dreams'. Eyes are already wide open at current findings, such as the fact that dreams don't happen in a flash: 'The time taken for a dream roughly matches the time that would be needed for the same actions in waking life.' Sounds exhausting.
REM sleep, it turns out, is the key to wellbeing – the brain gets 'offline' time to revise and classify information. Without it, there is a significant deterioration in judgment, speed and accuracy. Shift workers, take note.

Attacks by NHS trust's patients ‘do not surprise us', say Nottingham families
Emma Webber, mother of Barnaby Webber, said the failings of Nottinghamshire Healthcare NHS Trust 'continue to concern but sadly not surprise us' following the news that two men with paranoid schizophrenia, treated by the trust, stabbed members of the public in separate incidents weeks before the attacks. Josef Easom-Cooper and Junior Dietlin attacked six men in the county in 2023. Dr Susan Elcock, deputy chief executive and executive medical director at the trust, apologised 'for any aspect of our care which was not of the high standard our patients, their families and our communities deserve'. Another of the trust's patients, Valdo Calocane, went on to kill students Barnaby and Grace O'Malley-Kumar, both 19, and caretaker Ian Coates, 65, before attempting to kill three other people in the city in June 2023. A report into Calocane's care said he was not forced to have long-lasting anti-psychotic medication because he did not like needles. On behalf of the Nottingham families, Ms Webber told the PA news agency: 'Unless we expose those who are failing individually then nothing will ever change.' She said: 'The findings in the latest revelation about the Nottinghamshire mental health trust and its failings continue to concern but sadly not surprise us. 'As has been proven, it was a woefully inadequate, failing service. 'The statutory inquiry will provide our family with the opportunity to do the deeper dive and find out much more detail than any of the half-baked investigations that have taken place so far. 'What we find personally insulting is this continued 'unreserved apology and lessons will be learned' – they are not. They never have been. 'Unless we expose those who are failing individually then nothing will ever change. 'We completely stand united with anyone affected by any of these crimes, and in Barney, Grace and Ian's name, we will hold those to account who failed in any agency, and we will make sure that there is lasting change, not unreserved apologies and dusty reports on shelves.' In April 2023, Easom-Cooper stabbed a church-goer outside an Easter service and was sentenced to a hospital order in December of the same year. His mother, Shelly Easom, told the BBC he was sectioned in 2022 for three months and was discharged despite her telling the trust that he 'was not OK when he was released'. She told the broadcaster the attack could have been prevented if his condition had been taken more seriously. Dietlin stabbed five strangers in Nottingham and Mansfield nine weeks before the attack by Easom-Cooper and he also received a hospital order. Former police officer Keith Grafton, who was one of Dietlin's victims, told the BBC he was 'disappointed' his attacker had not received a prison sentence. The broadcaster said a report showed Dietlin had been involved with violent incidents with staff at Highbury Hospital in June 2022 and following his release, he took his medication 'very irregularly'. The BBC reported the day after his first attack on February 8 2023, he was visited by a staff member at the trust for a medication drop, but when community staff visited they found no signs of psychosis. Dietlin stabbed four more people between February 11 and 12. The trust said learning was identified in both cases – including capacity and risk assessment, liaison with police, medication drop-offs and follow-up and the role of families in working with patients who were harder to engage with. Dr Elcock said: 'Firstly, I apologise to those impacted by these incidents and for any aspect of our care which was not of the high standard our patients, their families and our communities deserve. 'Whilst we are unable to comment on individual cases due to patient confidentiality, I want to assure people that following any serious incident there is a robust review process which includes an initial management review to ensure any immediate learning and action takes place. 'This is then followed by a full investigation and a clear quality improvement plan detailing any learning and subsequent actions required. 'We have also implemented the new national patient safety incident response framework (PSIRF) which further strengthens this review and learning process. 'We know that it is really important for patients and families to be fully involved and I am confident our approach now ensures this happens, and that issues are addressed swiftly and transparently with patients involved in every aspect of their care. 'Above all, we remain fully committed to ensuring all our patients and their families receive the care they deserve, and our communities feel safe.'

Attacks by NHS trust's patients ‘do not surprise us', say Nottingham families
The mother of a student killed in the Nottingham attacks has said the victims' families stand united with anyone affected by stabbings carried out by those under the care of a 'woefully inadequate' mental health trust.

Time for more home grown tea cultivation?
ROWS of tea plants could become a more familiar sight on the hills of Wales and other parts of the UK in the future. Scientists at Aberystwyth University have been using machine-learning to analyse the chemical make-up of tea grown in non-traditional areas, including Powys in mid Wales and Dartmoor in south west England. They hope their findings will help emerging tea growers in the UK to develop breeding strategies, cultivation practices and processing methods which suit climate conditions in this part of the world. The research team are currently working with Dartmoor Estate Tea in Devon which is known for its unique microclimate and soil diversity. The study is focusing on six varieties of tea which have been selected by the estate for their adaptability to diverse environmental conditions and their potential for chemical diversity. Speaking on International Tea Day 2025, Dr Amanda J Lloyd, a senior researcher in food, diet and health at Aberystwyth University's Department of Life Sciences, said: 'This study is contributing to the growing field of metabolomics by providing a comprehensive chemical profile of tea grown in a non-traditional region. Our findings offer new insights into the adaptability of tea plants and their potential for cultivation in emerging regions, contributing to global food security and agricultural diversification. Further research will now need to be carried out and should include multi-seasonal sampling, comparisons with traditional tea-growing regions, and analysis of processed tea to provide a more comprehensive understanding of tea chemistry.' The study's findings have been shared in an academic paper published in Metabolites, an international, peer-reviewed open access journal. Dr Lloyd and her team have also been working with Buckhall Farm near Knighton in Powys which is pioneering tea cultivation in high-altitude Welsh conditions. The project was part of the first phase of the SBRI Agri-Food Technology Challenge, funded by the Welsh Government. The work builds on an innovative portfolio of research at Aberystwyth University focused on tea's health benefits, sustainable cultivation and consumer behaviour. Among other ongoing studies is the Better Brain project, which is funded by Innovate UK and which is currently recruiting for a trial investigating the effects of a supplement containing green tea extract, ginseng and omega-3s on cognitive function in middle-aged and older adults. The study is led by the Well-being and Health Assessment Research Unit (WARU) at the University, working with colleagues from the Department of Psychology and using advanced electroencephalogram (EEG) technology to assess cognition and wellbeing. Professor Nigel Holt from the Department of Psychology and the University's Associate Pro Vice-Chancellor, International, said: 'Tea is not only comforting but increasingly reveals itself to be a cognitive ally. Our research is helping us understand the deep biochemical relationships between tea's compounds and mental function. Better Brain is particularly exciting because it bridges nutrition, psychology and neurophysiology.'
