Medical microrobots that can travel inside your body are (still) on their way

MIT Technology Review

Okay, I know what you're probably thinking. We've been hearing about the use of tiny robots in medicine for years, maybe even decades. Where are my medical microbots already? They're coming, says Brad Nelson, who works in robotics at ETH Zürich. And they could be a game changer for a number of serious diseases.

10 functional health predictions for 2024, according to a doctor and a wellness expert

FOX News

Fox News Flash top headlines are here. Check out what's clicking on Heading into a new year, we all want to stay as healthy as possible -- and some doctors believe that identifying and eliminating the issues that cause disease are critical actions to take, as opposed to treating and reacting to symptoms afterward. Known as "functional medicine," this alternative form of health care has drawn mixed reviews over the years. Some claim it lacks scientific evidence and that the treatments aren't standardized.

How artificial intelligence is changing health care in treating stroke victims

FOX News

Neurosurgeon Dr. Paul Saphier on the warning signs to look for. I am a neurosurgeon who specializes in the treatment of acute strokes, brain bleeds, and tumors. Every second counts for my patients, and I am determined to help as many as I can. This Thanksgiving dinner, I left my family to operate on a patient with a life-threatening stroke. This is what you need to know about strokes and how artificial intelligence is helping surgeons like me save even more patients.

Drone delivers defibrillators for cardiac arrest faster than ambulance

New Scientist

Drones delivering defibrillators consistently outperform ambulances in the race to get life-saving treatment to people who have experienced heart failure, according to a landmark new trial in Sweden. Time is critical when it comes to reviving patients who have gone into cardiac arrest. Using a defibrillator to apply an electrical shock to a heart within 3 to 5 minutes of it stopping can lead to survival rates of up to 70 per cent. Yet fewer than 2 per cent of patients receive such treatment before emergency services arrive, with each minute of delay after the patient's heart has stopped reducing the probability of survival by 10 per cent. To see whether drones could cut the time taken to get defibrillators to collapsed patients, Andreas Claesson at the Karolinska Institute in Sweden and his colleagues launched a collaborative project with drone operator Everdrone and emergency services in western Sweden where drones and ambulances were dispatched to each suspected case of cardiac arrest. Across the 55 cases, drones were quicker than ambulances 67 per cent of the time, and by an average of 3 minutes and 14 seconds.

The best Apple Watch in 2023


Apple has just three smartwatches in its current lineup: the affordable Apple Watch SE, the advanced Apple Watch Ultra 2 and the flagship Apple Watch Series 9. All three offer fitness tracking, safety features, Siri support and iPhone integration, and all come in carbon-neutral configurations. But there are plenty of differences too, not the least of which is pricing: the Apple Watch SE starts at $250, whereas the Ultra 2 will run you a whopping $799. Internal sensors, displays and battery life vary from model to model, as well. In short, deciding the best Apple Watch for you might be trickier than you think.

How digital twins may enable personalised health treatment

The Guardian

Imagine having a digital twin that gets ill, and can be experimented on to identify the best possible treatment, without you having to go near a pill or a surgeon's knife. Scientists believe that within five to 10 years, "in silico" trials – in which hundreds of virtual organs are used to assess the safety and efficacy of drugs – could become routine, while patient-specific organ models could be used to personalise treatment and avoid medical complications. Digital twins are computational models of physical objects or processes, updated using data from their real-world counterparts. Within medicine, this means combining vast amounts of data about the workings of genes, proteins, cells and whole-body systems with patients' personal data to create virtual models of their organs – and eventually, potentially their entire body. "If you practise medicine today, a lot of it isn't very scientific," said Prof Peter Coveney, the director of the Centre for Computational Science at University College London and co-author of Virtual You.

New tech has spooky ability to detect future heart attack: study

FOX News

Fox News correspondent Gillian Turner has the latest on the president's focus amid calls for an impeachment inquiry on "Special Report." A new study found that artificial intelligence could be used to help detect risk signs and possibly even prevent sudden cardiac death. "When the data is fulsome and accurate and has a large enough sample size, AI will be able to identify patterns and correlations that humans might struggle to see, especially when they require two or more factors or have seemingly contrarian conclusions," Phil Siegel, the founder of the Center for Advanced Preparedness and Threat Response Simulation, told Fox News Digital. Siegel's comments come after the results of preliminary research by the American Health Association found that AI was able to identify people who were at more than a 90% risk of sudden death, according to a report on the study in Medical Xpress. WHAT IS ARTIFICIAL INTELLIGENCE (AI)?

Bad grammar is so maddening it activates the 'fight or flight' response within the human body, study finds

Daily Mail - Science & tech

For many, bad grammar can be maddening. Now experts have discovered it really does cause a physical reaction – and even affects our heart rate. Instances of bad grammar can include mixing up tenses within a sentence, confusing the singular and plural, using a double negative or misusing a comma. Examples of the pet peeve include'We don't need no education', 'I ate porridge for breakfast and drink milk' or'Anna and Mike is going skiing'. Researchers from the University of Birmingham recruited 41 British English-speaking adults who listened to 40 English speech samples, half of which contained grammatical errors.

Energy-efficient transistor could allow smartwatches to use AI

New Scientist

A reconfigurable transistor can run AI processes using 100 times less electricity than the standard transistors found in silicon-based chips. It could help spur development of a new generation of smartwatches or other wearable devices capable of using powerful AI technology – something that is impractical today because many AI algorithms would rapidly drain the batteries of wearables built with ordinary transistors. The new transistors are made of molybdenum disulphide and carbon nanotubes. They can be continuously reconfigured by electric fields to almost instantaneously handle multiple steps in AI-driven processes. In contrast, silicon-based transistors – which act as tiny on-or-off electronic switches – can only perform one step at a time.

Pixel Watch 2 review: Not leading the way, but no longer lagging


Being stressed is not usually a good thing. But when you're reviewing a high-profile smartwatch that touts stress-tracking as one of its most noteworthy new features, experiencing stress can be helpful. During the time I tested the Pixel Watch 2, I was going through a lot emotionally. I was maid of honor at our senior commerce editor's wedding, had a family funeral to think about and was getting updates on the results of my best friend's cancer diagnosis. Add to that the frenzy of Google's hardware launch event and a super tight deadline for this review, and my mental landscape became the perfect testing scenario for the Pixel Watch 2's body-response sensor. That's not the only new feature Google is bringing to its sophomore smartwatch.
