Why Soap Is Still Our Best Weapon Against Coronavirus

One of the most effective things you can do to protect yourself from catching a germ and becoming a statistic, whether it’s a global pandemic like COVID-19 or just every single other day of your life, is something that people have been trying to get you to do since you were like 2.

Fixing Daylight Saving Time Is THIS Easy

Daylight saving time is a perfect example of how a few people with the best of intentions can end up annoying millions of the rest of us for the better part of a century. And it’s time we take an honest look at how we got to this place where half the world comes unstuck in time twice a year, and ask if the supposed advantages for springing forward and falling back still hold up!

Sunlight Is Way Older Than You Think. Here’s Why…

If the sun instantly switched off like a light bulb–which can’t happen, by the way–then we wouldn’t know for almost 8 and a half minutes. Light travels at the fastest speed there is, but it still takes almost 500 seconds to get to Earth. But the most amazing thing about the sunlight we see is it’s actually SUPER old. How is that possible? Because of the physics and mathematics of random walks.

Why are Human Babies So Helpless?

Within an hour of a baby giraffe being born, it’s standing, walking, and nursing on its own. Human babies on the other hand? We’re born unable to move or eat on our own, we can’t communicate or fully sense our world, and we leak EVERYWHERE. If humans are so smart, why are our babies so… un-smart? You may think it’s all about head size, but the real science is more complex.

Can Supercrops Feed 10 BILLION People?

If you tried to sum up the last 150 years or so in one image, a chart of exponential growth would be a good place to start. You could apply it to life expectancy. Or compound interest. Or any number of things. But especially population growth. As we face a future population of 10 billion and a world impacted by climate change, how will we do a Green Revolution 2.0?

Can Trees Really Fight Climate Change?

For eons, nature has relied on photosynthesis as a big way to keep carbon dioxide levels from getting out of control. But as we have put more carbon into the air, we’ve also cut down many of the forests we need to suck that carbon up. So big tree-planting initiatives like #TeamTrees to the rescue, right? Actually, we need to think bigger. Here’s 3 ways trees can help us solve climate change.
