Try This – 4 Shares For The Week

Today, I’m sharing some helpful, promising, and hopeful news. I hope you find these shares as fascinating as I did. 

1. Can this exercise strengthen your heart? 

2. This simple hack could help prevent Lyme disease 

3. Less pesticides with artificial intelligence?

4. The vitamin that might slow down coronary calcium 

Let’s dive in… 

1. Strength Training Improves Women’s Hearts

In a two-year randomized controlled trial, researchers assigned older women to a supervised whole-body resistance training program and tracked changes in their heart structure and function over time. The women who lifted weights experienced favorable "cardiac remodeling." Essentially, their hearts aged more slowly than those who didn't train.

Specifically, resistance training helped prevent increases in the thickness and mass of the heart's main pumping chamber, which commonly occurs with aging and can raise the risk of heart failure.

The women also showed improvements in diastolic function, which refers to the heart's ability to relax and fill with blood between beats; this is a key marker of cardiovascular health that often declines with age.

Beyond the heart, the women improved strength, physical function, and several markers of metabolic health.

What's particularly striking is that these are benefits we've traditionally associated with aerobic exercise. This study suggests that strength training may offer similar protection against age-related changes in the heart.

Another reason why all people, including women, should prioritize strength training.

2. Give an Owl Some Love—You Could Help Slow the Spread of Lyme

If Lyme disease is a concern where you live, tick checks are important. But there's another layer of prevention that gets a lot less attention: reducing the number of infected ticks around your home.

Here's a fun fact I learned from the Give a Shit About Nature newsletter: Most people think of deer as the biggest carriers of ticks. They should actually be worried about tiny white-footed mice. A single mouse can carry up to 50 ticks at once! And the more mice, the more ticks in your area. 

One strategy to prevent this is to make your yard more welcoming to the mouse's natural predators. Researchers at the Cary Institute have found that healthy predator populations (like Owls) help keep mouse numbers in check, which may ultimately reduce the number of infected ticks in the environment.

A yard that attracts owls may be a yard with fewer mice—and potentially fewer Lyme-carrying ticks.

One important caveat: Avoid rodent poisons. These toxins move up the food chain and can kill the very predators, including owls and other birds of prey, that help control mouse populations naturally.

3. Could AI Help with a Pesticide-Free Future?

I came across an incredible video on X.com this week that made me genuinely excited about the future of AI.

The video showed an autonomous robot driving through a strawberry field in the middle of the night. It wasn’t using pesticides or spraying chemicals; it was just using ultraviolet (UV) light.

As it moves through the rows, the robot uses UV light to kill certain pathogens and pests while the farmers sleep.

You might have seen in the news lately that strawberries are consistently one of the most heavily sprayed crops in agriculture. They're so susceptible to insects, mold, and disease that farmers often rely on repeated pesticide applications to protect yields.

Now imagine a future where robots can patrol fields overnight, targeting problems with precision instead of blanketing crops with chemicals.

Will this eliminate pesticides entirely? Probably not. Agriculture is complicated, and no single technology is a silver bullet. But it's a glimpse of what's possible when automation, robotics, and AI are applied to real-world problems.

AI conversations often focus on the scary stuff: job displacement, misinformation, privacy concerns, and energy use. Some of those concerns are valid. But it's easy to miss the other side of the story.

The same technologies that generate headlines may also help us grow food with fewer chemicals, reduce waste, improve efficiency, and create healthier agricultural systems.

When people talk about AI, I think we're often asking the wrong question. Instead of asking, "Is AI good or bad?" it may be more useful to ask, "What problems can it help us solve?"

4. New Study: Vitamin K Slows Coronary Calcium

A brand-new study landed this week, and it caught my eye for one simple reason: It’s the first time we have ever seen vitamin K actually move the needle on heart health in a real clinical trial. 

Researchers in the Netherlands gave 180 people with early heart disease either 360 micrograms of vitamin K2 (MK-7) daily or a placebo, then tracked the buildup of calcium in their arteries for two years.

The result? The placebo group's artery calcium climbed from 145 to 214. The vitamin K group went from 135 to 184. Less buildup, and the difference held up even after adjusting for other factors. That has never been shown before. 

But there are some limitations. The study only measured calcium on a scan. It never tracked actual heart attacks or strokes, and calcium in a plaque can sometimes be the body's way of stabilizing it. So slowing it down might be good, or it might not be. We don’t know yet.

My take? My functional medicine doctors have recommended vitamin K2 alongside vitamin D for years because the risk is low and the logic is sound; this is the first real evidence that it does something measurable. But anyone claiming it "reverses" heart disease might be speaking too soon.

If you want a full, nuanced view, vascular surgeon Dr. Lily Johnston did a great breakdown of the trial on YouTube.
