It’s time for “Nerd News,” covering the most important news for your brain you may have missed. Here’s a quick rundown of this week in science . . .
1. One thing Apple Watches still can’t do is check blood pressure. But researchers in Texas just came up with something that can . . . an “electronic tattoo.” That’s what they call it, but it’s not really a tattoo. It’s made of ultra-thin graphene that sticks to your wrist and monitors blood pressure 24/7.
2. The world’s largest bacteria was discovered in the Caribbean, and you don’t even need a microscope to see it. Each one of them is about the size of an eyelash. They don’t think it’s all that dangerous for humans though.
3. A giant sunspot several times bigger than Earth is pointed straight at us right now. They’re hoping it doesn’t shoot a blast of radiation at us in the form of a solar flare. If it does, it could mess with satellites, GPS, and cause radio blackouts.
4. In other space news: The Mars Perseverance rover spotted a round rock balancing on top of a boulder . . . almost like someone, or some THING, put it there. NASA says it’s no big deal though, and actually pretty common.
5. And finally: A former astronaut named Tim Peake did an interview, and said the Space Station smells like farts. They apparently tend to linger inside the station. Plus, you can’t burp in space. So the gas in your body only has one way out.
