Sleep plays a central role in memory consolidation - the process by which newly acquired information is stabilized and integrated into long-term memory stores. Research from institutions including Harvard Medical School and the Max Planck Institute for Human Cognitive and Brain Sciences has shown that different stages of sleep contribute to different types of memory. Slow-wave sleep, or deep sleep, appears to be particularly important for declarative memory - the kind that stores facts and events.
If it continues to spread past the demarcation that we usually draw using a skin marker-we say Sharpie, but it's a skin marker-we say that this is spreading. Diagnosis: possible sepsis. Varshavski was not talking to the patient or to nursing staff. He was not even in a hospital. He was speaking into a camera in a two-bedroom apartment on the fifty-sixth floor of a building in Hell's Kitchen, in a makeshift studio where he records videos and his popular podcast.
Dutch law gave Oosterhoff the power to grant her request. In 2002, the Netherlands began allowing doctors to administer death to patients who make "voluntary and well considered" pleas to end "unbearable" suffering from any medical condition—provided there is no "prospect of improvement" and no "reasonable alternative" to dying. Eighteen-year-olds are adults and can request euthanasia even over family objections.
We were $16,000 out of pocket, with weekly blood work, invasive ultrasounds, sperm quality testing, genetic testing, eating well, exercising, daily cold plunging, expensive vitamins, excessive pregnancy testing and more tears than I would like to remember. We were at a loss, with an official diagnosis of unexplained infertility.
The failure to prescribe the medication correctly was a failure in basic care and this was compounded by the failure to recognise the hypocalcaemia and the mis-prescribing across multiple shifts and clinical disciplines. There were thus multiple missed opportunities to recognise the prescribing error and overdose and its effects in a timely fashion that may have improved the outcome for Sidra and prevented her death.
The weight loss jabs Ozempic, Mounjaro and Wegovy - a type of medicine containing semaglutide - are increasingly being seen as a medical wonder of the age. They bring great benefits to people with diabetes and obesity.
Brazilian far-right former President Jair Bolsonaro, imprisoned for plotting a coup after he lost the country's last election, is receiving treatment in an intensive care unit after being hospitalised with bronchopneumonia. The DF Star hospital in Brasilia said in a statement on Saturday that the 70-year-old was in a stable condition despite being diagnosed with worsening kidney function.
After graduating high school and being selected in the military draft, Steele served in France, Germany, Belgium and Czechoslovakia toward the conclusion of the second world war. His duties involved seeking out remnants of the Nazi army and helping survivors of German concentration camps return home. Steele subsequently earned a promotion to staff sergeant and was assigned to guard imprisoned defendants at the Nuremberg trials, including convicted war criminal Hermann Goring, the Nazis' second-in-command.
For those who are unable to take HRT for varying reasons, options have historically been limited, and we have heard clearly from patients how difficult that has been. The evidence shows fezolinetant can meaningfully reduce symptoms, and was found to be cost effective, offering value for the taxpayer. This decision will give much-needed relief to those for whom HRT is unsuitable.
Young, two-month-old lab mice housed with older, 18-month-old mice showed really impaired cognition. Researchers exposed young mice raised in a sterile, microbe-free environment to gut bacteria from old mice, causing the younger animals to perform worse on cognitive tests, as if they had prematurely aged, just like the cohoused mice.
EchoPrime, a video-based vision-language model, analyses echocardiogram footage and generates a written report of cardiac form and function. Its findings were published in Nature (volume 650, pages 970-977) in February 2026, under the title 'Comprehensive echocardiogram evaluation with view primed vision language AI.'
New research, published as a pre-print, suggests that semaglutide could be mass produced for $3 (about 2.35) for a monthly dose in its injectable form. Newer formulations, taken as a pill rather than an injection, could be made for about $16 a month.
Leading robotic urological surgeon Professor Prokar Dasgupta said it felt 'almost as if I was there' as he carried out a prostrate removal on Paul Buxton. The cancer patient, 62, said it had been a 'no-brainer' to take part and become 'part of medical history'. It is hoped that remote robotic surgery could spare future patients the 'vast expense and inconvenience' of travelling for treatment, and help deliver better healthcare to people in more remote locations.
Performing the procedure 1,500 miles away, from London's Harley Street district, was Prof Prokar Dasgupta, a professor of urology who heads The London Clinic's robotic centre of excellence. With the help of technology services provider Presidio, Dasgupta used a console in London to guide the Toumai Robotic System, made by Microport, through an intricate sequence of steps to successfully give Buxton a prostatectomy, a surgical removal of the prostate.
The pig organ filtered the man's blood for a few days while he waited for a human liver transplant. The man has since received a human liver and is recovering well, says Lin Wang, one of the surgeons who led the procedure in January at Xijing Hospital of the Air Force Medical University in Xi'an, China.
It was really hard at that time, I have never been in such a dark place before. I feel like the steroids made me feel alone. I have such a supportive family, but it put me in a pit and I didn't know how to get out of it. I had insomnia and I know that is an effect from the steroids, but I didn't realise how much I would be affected by it.
Expectant mothers lost an average of nearly five per cent of their grey matter, the tissue responsible for processing emotions, information, and empathy. This loss isn't a sign of decline as Lead researcher Professor Susana Carmona of the Gregorio Marañón Health Research Institute likened it to pruning a tree. 'Some branches are cut to make it grow more efficiently,' she explained.
