The 2025 Tech Power Players in the health tech sector
A new study will cover research ranging from improving sleep to warding off the effects of aging.
MacRae grew up in Scotland, coming to the Boston area in 1991 for a fellowship at Harvard.
The study data could be used to train artificial intelligence models. 'Having a data stream like this is actually incredibly valuable,' MacRae says, 'and would allow people to predict things that you might not have imagined otherwise.'

If You Buy 2 AirTags, Amazon Gives You 2 More for Free Just After Prime Day
Amazon is continuing the Prime Day excitement with an offer that's hard to resist: AirTag 4 Pack is still its all-time low price. Now, you can get four AirTags for just $64 which is a staggering discount from the usual $99. To give you some perspective, a single AirTag normally sells for $29, so with this deal, you're getting two and two more for free. Even better, this deal isn't limited to Prime members, anyone can take advantage of it. See at Amazon The AirTag has become a must-have accessory for keeping track of your most important belongings: With effortless one-tap setup, all AirTags instantly connect to your iPhone or iPad so the process is seamless and easy. Once activated, you can use the Find My app to locate your stuff, from your keys, wallet and backpack to your luggage when you're away traveling. One of AirTag's biggest advantages is the way it so smoothly fits into Apple's Find My network: If you misplace something that's nearby, you can employ Precision Finding which is powered by Ultra Wideband technology to get directions with the help of your AirTag directly to it. If your item is more distant, Apple's enormous network of hundreds of millions of Apple devices can help find it, all while keeping your information private. You can even make an AirTag lose in Lost Mode, and you'll get an automatic notification if it gets discovered by another device in the Find My network. It's easy and secure to share location and you can even share an AirTag with up to five people. The built-in speaker in each AirTag lets you play a sound to find your stuff right away or simply ask Siri for help. The AirTag is even IP67-certified so it's water and dust proof, and you don't have to worry if it gets wet or ends up in a dirty place. The battery is also replaceable and lasts over a year so you won't need to take care of it much, and replacing the battery won't be a hassle. With the price this low, it's smart to act fast before the promotion ends. See at Amazon

Harvard Found a Way to Make Rubber 10x Tougher and It Could Be Big for Cars
The latest car news, reviews, and features. Natural rubber is a wonder material. Few discoveries or innovations come close to its impact on manufacturing, and the car industry is just one of many that depend on it for critical components, such as gaskets, seals, and tires. There's just one problem: It cracks, and once that happens, it's not good for much. That's why researchers at the Harvard School of Engineering and Applied Sciences started tooling around with natural rubber here recently to see if they could make it more durable. And what do you know, they were able to make it 10 times tougher than before with a tweak to the vulcanization process. See, the science involved in vulcanized rubber production hasn't changed much since Charles Goodyear patented it in 1844. You start with natural rubber latex that comes from Hevea trees, and once it's harvested, it's coagulated, dried, mixed with additives, shaped, and heated. The high-intensity process forms short polymer chains within the material, as the Harvard SEAS writes, resulting in chemical bonds. The Harvard scientists had an idea: 'What if we're gentler with it?' Sounds crazy, I know, but that one tweak brought about a result that surprised even their bright minds. It was instantly four times better at resisting slow crack growth, even after repeated stretching. 'We imagined that the properties would be enhanced maybe twice or three times, but actually they were enhanced by one order of magnitude,' said Zheqi Chen, a former SEAS postdoctoral researcher and first co-author of the paper. Harvard School of Engineering and Applied Science The change in process, which was based on latex processing methods, preserved the long polymer chains rather than forming shorter ones. Long 'tanglemers' inside the material resemble spaghetti noodles rather than a tightly-bound grid. Stress is then able to be spread out across those tanglemers, greatly improving its resistance to cracking and snapping. Not only is it more resistant to cracks, but it becomes tougher under the conditions that would normally cause natural rubber to fail. It wouldn't be accurate to call the material 'self-healing,' but as the new rubber stretches and small cracks form, those spaghetti tanglemers allow more crystallization. That means the overall strength increases under those circumstances. This video demonstrates it well: This process isn't especially well-suited to automotive applications like tires, at least in its current form. Water evaporation is high, yielding a smaller volume of material than companies would want to wrap around a car's wheels. The Harvard SEAS writes that, for now, it's better suited for gloves and other thin applications. You can fill in the blank there, but if scientists can find a way to upscale the process so that it works for automotive seals, then it could be good news for people in sunny climates some 10 to 15 years later. All the people in Phoenix are hoping that the time comes sooner rather than later. Got a tip or question for the author? Contact them directly: caleb@

Want Better Sleep or More Energy? Time Your Showers Right
Morning or night? It's one of the most debated bathroom routines out there, but according to sleep researchers and wellness experts, the best time to shower might depend entirely on what you want to get out of it. If you're struggling to fall asleep or stay asleep, switching to a warm nighttime shower could make a surprising difference. Time reported that research from Shahab Haghayegh, a sleep expert at Harvard Medical School, shows that a warm shower taken one to two hours before bed helps align your body's temperature with its natural circadian rhythm. That drop in core body temperature signals to your brain that it's time to wind down, making it easier to fall asleep and stay asleep. 'The body clock doesn't change that easily,' Haghayegh says. 'But consistent nighttime showering can help shift your bedtime earlier and improve sleep quality.' There's also a creative bonus. Evening showers, when your mind is less focused and more relaxed, can trigger free association, giving way to breakthrough ideas or solutions. In short, it's the perfect environment for spontaneous thinking. Prefer morning showers? You're not wrong either. Cold morning showers, especially those paired with stimulating scents like rosemary or citrus, can kickstart alertness, improve your mood, and even enhance circulation. They also reinforce your body's natural temperature rise after waking, which helps shake off grogginess and get you into gear faster. For many, it's also a matter of practicality. Morning showers tame unruly bedhead, freshen you up post-sleep, and help you start the day with focus. Meanwhile, nighttime showers may be essential for those who sweat a lot, live in polluted areas, or want to keep their sheets clean. Ultimately, it's not about choosing the 'right' side. It's about aligning your routine with your goals. Whether you're looking to recharge or reset, your shower can be more than just a rinse. It can be a habit that supports better sleep, sharper focus, and a healthier Better Sleep or More Energy? Time Your Showers Right first appeared on Men's Journal on Jul 11, 2025
