An investigation found that real video of medical professionals is being manipulated using AI. An investigation found that real video of medical professionals is being manipulated using AI. TikTok and other social media platforms are hosting AI-generated deepfake videos of doctors whose words have been manipulated to help sell supplements and spread health misinformation. The factchecking organisation Full Fact has uncovered hundreds of such videos featuring impersonated versions of doctors and influencers directing viewers to Wellness Nest, a US-based supplements firm. All the deepfakes involve real footage of a health expert taken from the internet.

Doctors from Scotland and the US have completed what is thought to be a world-first stroke procedure using a robot. Prof Iris Grunwald, of the University of Dundee, performed the remote thrombectomy - the removal of blood clots after a stroke - on a human cadaver that had been donated to medical science. The professor was at Ninewells Hospital in Dundee, while the body she was operating on while using the machine was across the city at the university. Hours later, Ricardo Hanel - a neurosurgeon in Florida - used the technology to carry out the first transatlantic surgery from his Jacksonville base on a human body in Dundee over 4,000 miles (6,400km) away. The team has called it a potential game changer if it becomes approved for use on patients.

A woman who was plunged into sudden menopause after surgery to remove both ovaries is spearheading efforts to change NHS policy. Kate Dyson, 44, from Hastings, East Sussex, underwent the surgery six months ago after having a subtotal hysterectomy in 2021 to remove her uterus - a procedure which leaves the cervix in place. The mum-of-three says she was completely unprepared for the impact of surgical menopause, which is triggered by both ovaries being removed. Honestly, it was like falling off a hormonal cliff edge, she told BBC Radio Sussex. Within hours of the surgery I was home the same day.

Randomized trials have traditionally been the gold standard for informed decision-making in medicine, as they allow for unbiased estimation of treatment effects under mild assumptions. However, there is often a significant discrepancy between the patients observed in clinical practice and those enrolled in randomized trials, limiting the generalizability of the trial results [12, 43]. To address this issue, the U.S. Food and Drug Administration advocates for using observational data, as it is usually more representative of the patient population in clinical practice [30, 39]. Yet, a major caveat to this recommendation is that several sources of bias, including hidden confounding, can compromise the causal conclusions drawn from observational data. In light of the inherent limitations of randomized and observational data, it has become a popular strategy to benchmark observational studies against existing randomized trials to assess their quality [4, 13]. The main idea behind this approach is first to emulate the procedures adopted in the randomized trial within the observational study; see e.g.

Amazon's Alexa voice assistant is already a fount of knowledge on health topics ranging from the symptoms of chicken pox to how to relive a migraine. Now Amazon has teamed up with independent website Menopause Matters to provide answers to some of the most commonly asked questions around menopause. Alexa users in the UK can ask questions including'What treatments are available for the menopause?', 'What is perimenopause?', and'What are the benefits or risks of Hormone Replacement Therapy for menopause?' The news comes amid warnings that women going through the menopause are often mis-diagnosed with depression, because GPs do not know all the symptoms.

Dr. Stephen Friend on how machine learning will disrupt medicine - but why we need decision making to remain with the patient. Next Now: The 21st century has ushered in a new age where all aspects of our lives are impacted by technology. How will humanity anticipate, mitigate, and manage the consequences of AI, robots, quantum computing and more? How do we ensure tech works for the good of all? Dr. Stephen Friend is a globally acclaimed serial entrepreneur and biomedical researcher.

"Is it OK to put a jade egg in my vagina?" A team of New Zealand researchers posed these questions and 47 others to digital assistants to determine how effectively Siri et al. could answer questions on sex. The informal study, which was not peer-reviewed, was published online Wednesday by the medical journal BMJ. Three researchers used laptops to type out questions to Google.co.nz, and then used iPhone 7 devices to ask the Google Assistant app and Siri the same questions. The responses were rated by quality, with expert sources like universities and hospitals ranked most highly.

What do we all have in common? Surprisingly, the answer is menopause. But scientists still haven't quite figured out why this phenomenon exists. After all, if the purpose of evolution is to make sure that we most effectively pass on our genes, then why would women stop reproducing after a certain age? A study published on Thursday in PLOS Computational Biology may offer some insight into the evolution of menopause in humans.

Gravitational waves were detected for the first time by LIGO, the Laser Interferometer Gravitational-Wave Observatory, it was announced in February. These are predicted by Einstein's theory of general relativity, which says that massive objects warp space-time around them. When these objects accelerate, they form gravitational waves, ripples in the fabric of space-time. Their presence was inferred in 1974, but none had been observed directly – until now. In May, Neanderthals were credited with building a series of mysterious large stalagmite structures in a French cave. Roughly 175,000 years old, they are made from 400 individual stalagmites snapped from the cave floor and laid in a circle.
