1. A new force of nature is reshaping the planet, study finds

   Human societies didn’t just adapt to the planet—they learned to reshape it. From early fire use to today’s global supply chains, our cultural and social innovations have unlocked extraordinary power to transform Earth and improve human life. But that progress has come with serious costs, including climate change, pollution, and mass extinction. Instead of framing this era—the Anthropocene—as pure crisis, Erle Ellis argues it’s also proof of something hopeful: when people work together, they can drive massive positive change.

2. Scientists develop dirt-powered fuel cell that could replace batteries

   Scientists have developed a fuel cell that uses microbes in soil to produce electricity. The device can power underground sensors for tasks like monitoring moisture or detecting touch, without needing batteries or solar panels. It works in both dry and wet conditions and even lasts longer than similar technologies. This could pave the way for sustainable, low-maintenance sensors in farming and environmental monitoring.

3. What caffeine does to ants could change pest control

   Caffeine doesn’t just perk up humans—it can sharpen ants’ minds too. Invasive Argentine ants given caffeinated sugar learned to find food much more efficiently, taking straighter paths and reducing travel time by up to 38%. They weren’t faster, just more focused, indicating improved learning. This unexpected effect could make pest control baits far more effective.

4. Artificial neurons successfully communicate with living brain cells

   Engineers at Northwestern University have taken a striking leap toward merging machines with the human brain by printing artificial neurons that can actually communicate with real ones. These flexible, low-cost devices generate lifelike electrical signals capable of activating living brain cells, a breakthrough demonstrated in mouse brain tissue.

5. Scientists say this type of olive oil could boost brain power

   Extra virgin olive oil might help protect your brain by working through your gut. A two-year study found that people who consumed it had better cognitive performance and more diverse gut bacteria than those using refined olive oil. Researchers even identified specific microbes linked to these benefits. The findings suggest that choosing high-quality olive oil could be a simple way to support brain health as you age.
