My wife and I have recently bought new smartwatches (me: Garmin Venu 2, her: Fitbit Versa 3) and the things they tell us really makes a difference to how we exercise. What’s reported here looks like next level even to the detailed stats we’ve got already.
The team identified a set of 147 proteins that could indicate a person’s VO2max, a marker of cardiorespiratory fitness, before the exercise program, and then a set of 102 proteins that could indicate the change in VO2max after it had been completed. Some of these proteins were also found to be linked to a higher risk of early death, highlighting a connection between cardiorespiratory fitness and long-term health.
“We identified proteins that emanate from bone, muscle, and blood vessels that are strongly related to cardiorespiratory fitness and had never been previously associated with exercise training responses,” says Gerszten.
Based in these revelations, the scientists developed what they call a protein score, which could be used to predict how much a person’s VO2max would change as a result of the exercise. Baseline levels of certain proteins were able to predict who would respond to the exercise with more reliability than established patient factors, according to the scientists, and also predicted which subjects would be unable to significantly improve their VO2max even after a sharp uptake in physical activity.
✨ The World’s Oldest Story? Astronomers Say Global Myths About ‘Seven Sisters’ Stars May Reach Back 100,000 Years — “Why are the Australian Aboriginal stories so similar to the Greek ones? Anthropologists used to think Europeans might have brought the Greek story to Australia, where it was adapted by Aboriginal people for their own purposes. But the Aboriginal stories seem to be much, much older than European contact. And there was little contact between most Australian Aboriginal cultures and the rest of the world for at least 50,000 years. So why do they share the same stories?”
🚶♂️ The joy of steps: 20 ways to give purpose to your daily walk — “We need to gallivant around outside in daylight so that our circadian rhythms can regulate sleep and alertness. (Yes, even when the sky is resolutely leaden, it is still technically daylight.) Walking warms you up, too; when you get back indoors, it will feel positively tropical.”
🔐 How Law Enforcement Gets Around Your Smartphone’s Encryption — “Cryptographers at Johns Hopkins University used publicly available documentation from Apple and Google as well as their own analysis to assess the robustness of Android and iOS encryption. They also studied more than a decade’s worth of reports about which of these mobile security features law enforcement and criminals have previously bypassed, or can currently, using special hacking tools.”
😲 The Ethics of Emotion in AI Systems (Research Summary) — “There will always be a gap between the emotions modelled and the experience of EAI systems. Addressing this gap also implies recognizing the implicit norms and values integrated into these systems in ways that cannot always be foreseen by the original designers. With EAI, it is not just a matter of deciding between the right emotional models and proxy variables, but what the responses collected signify in terms of human beings’ inner feelings, judgments, and future actions.”
