Welcome to Nerd News, where we cover the most important developments in science so you can sound incredibly intelligent the next time somebody asks what you did all weekend.
This week's headlines include a toilet designed for astronauts, dinosaurs getting hit with an absolutely brutal heat wave, and evidence that your Chihuahua might secretly be a tiny coyote.
So... let's get nerdy.
1. The iThrone: A Toilet for Earth and Space
Former NASA researcher Diana Yousef invented a waterless toilet called the iThrone after realizing something pretty interesting:
People who don't have access to plumbing face some of the same sanitation problems as astronauts.
Think about that the next time you complain because your bathroom is two steps farther away than you'd like.
The iThrone rapidly evaporates about 95% of the water in human waste, making what's left safer to handle in places without traditional sewage systems.
And this isn't just some science experiment sitting in a lab. The toilets are now serving roughly 20,000 households in places including Uganda, Panama and the United States.
Honestly, this is one of those inventions that makes you wonder why we haven't figured this out sooner.
Humanity has invented smartphones that can translate languages in real time.
We can land rockets upright.
We can send a picture of a sandwich to somebody halfway around the world.
And we're still basically saying, "Okay, everybody, line up and wait for the plumbing."
2. The Dinosaurs Didn't Just Have a Bad Day
We already knew the asteroid that wiped out the dinosaurs was having a pretty rough impact on the neighborhood.
New research suggests it may have been even worse than scientists previously thought.
Researchers say fine dust blasted into the atmosphere after the asteroid impact trapped heat from falling debris, exposing animals on land to roughly 17 times a lethal heat dose.
In other words, if you were a dinosaur standing outside that day, things went from:
"Hey, what's that in the sky?"
to:
"OH, THIS IS BAD."
Plants caught fire.
Temperatures soared.
And suddenly being the dinosaur who liked hanging out underground wasn't such a weird hobby.
Animals that could burrow or take shelter in water apparently had a much better shot at surviving.
So, basically, the prehistoric survival guide was:
Get underground. Get in the water. Don't look up.
Michigan readers may recognize the strategy.
Except instead of an asteroid, we're talking about winter.
3. Your Chihuahua Might Be Part Coyote
And finally, we have perhaps the most shocking scientific discovery of the week:
Chihuahuas may have coyote DNA.
A new genetic study found that these tiny dogs share portions of their DNA with coyotes.
Researchers at Stanford University discovered the connection while testing software designed to trace the ancestry of animal genomes.
Scientists don't know exactly when coyotes entered the Chihuahua family tree, but the evidence suggests it happened before European contact with the Americas.
And suddenly a lot of things make sense.
That Chihuahua that weighs eight pounds but thinks it can take on a German shepherd?
Coyote.
The one that barks at absolutely nothing?
Coyote.
The one that stares at you like it knows your darkest secrets?
Definitely coyote.
Meanwhile, the Chihuahua is probably sitting there thinking:
"Finally. They're starting to figure it out."
That's Your Nerd News
So what did we learn this week?
Astronauts need toilets.
Dinosaurs really, really needed sunscreen.
And Chihuahuas might be tiny coyotes with anger-management issues.
Science is amazing.
And honestly, if next week's Nerd News tells us that Michigan squirrels are secretly running an underground intelligence operation, we're not even going to be surprised.
Stay curious, stay nerdy—and if you see a Chihuahua in the woods...
Maybe don't make eye contact.
