Male cats, just like male humans, have an X and Y chromosome. So any male cat with this mutation ends up orange. Female cats need the mutation on both of their X chromosomes to be fully orange, which is statistically less likely. So nearly all calico and tortoiseshell cats are female because this mutation is found on only one of their X chromosomes.

So no orange cats were harmed in the pursuit of this genetic mystery. Well, that's good. In fact, study author Greg Barsh says that the Stanford team partnered with cat lovers and community scientists to gather DNA samples from dozens of different orange cats.

Are their orange colors linked to their sex chromosomes too? So actually, no, their orange color arises from regular chromosomes known as autosomes.

Yes, Juana. I just bought a bike. I just started biking. I don't want to get hit by a car. So I was very interested in the study where like computer scientists created a system called proxy cycle. It's a sensor to monitor how close cars get to cyclists. The scientists deployed the sensor on 15 bikes over the span of two months in Seattle, Washington.

And that might seem like an obvious connection to make, but the lead researcher Joe Breda at the University of Washington has surveyed cyclists and found that people who were like new to city biking weren't all that good at like gauging how safe routes were. And that's where this answer could help. Like he just wants to encourage more people to bike.

And you know, Juana, we've gotten so used to like maps when we're driving, like people's devices telling companies like Google where traffic is, allowing them to reroute themselves. Imagine something like that for cyclists where all of this like crowdsourced data from the sensors can feed into a map that helps like find safer bike routes.

Like in a regular rapid heart rhythm? Yes. Right. AFib is common, affecting about 10 million U.S. adults. And now AFib isn't necessarily life-threatening, but it can be dangerous, especially for older people. And gum disease is also really common. It affects nearly half of U.S. adults.

To study the connection, his team infected mice with a bacteria associated with gum disease and found that these mice developed AFib more easily than those without the bacteria. They also saw that mouth bacteria migrated to the heart, like in mice and in humans.
