If you're contemplating ​getting a dog, recent scientific research provides a great reason why you should go for it. Owning a dog seems to be good for your health. According to a Swedish study published in Scientific Reports in 2017, dog owners have a reduced risk of death compared to non-owners.

The benefits seem to be most significant for people who live by themselves. In single-person households, dog ownership is associated with a 33 percent reduction in mortality risk and an 11 percent reduction in the risk of heart attacks compared to individuals who live alone and don’t have a dog.

Dog ownership doesn't just benefit singles, though. Among multi-person households, the researchers found that having a dog reduced the overall risk of death by 11 percent, and the risk of dying from cardiovascular disease by 15 percent, according to Fox8.

And though researchers found a benefit in dog ownership of all breeds, owners of hunting breeds such as ​retrievers, terriers, and scent hounds showed the lowest rates of cardiovascular disease.

One major caveat with these results is that the study couldn't provide direct evidence that getting a dog causes you to be healthier or prevents cardiovascular disease, just that people who own dogs tend to have lower mortality rates associated with cardiovascular disease. There may be an ancillary reason that dog owners, on the whole, have fewer fatal cardiovascular issues, such as that people who walk their dog every day often get more exercise than the general population. But it could also be that the type of people who get dogs also tend to be healthier for whatever reason.

But if you're on the fence about owning a dog, just know that getting one could be a life-extending decision.

And there are plenty of other benefits that come with owning a dog. Read more about them here.

A Prehistoric Great White Shark Nursery Has Been Discovered in Chile

Great white sharks (Carcharodon carcharias) may be one of the most formidable and frightening apex predators on the planet today, but life for them isn’t as easy as horror movies would suggest. Due to a slow growth rate and the fact that they produce few offspring, the species is listed as vulnerable to extinction.

There is a way these sharks ensure survival, and that is by creating nurseries—a designated place where great white shark babies (called pups) are protected from other predators. Now, researchers at the University of Vienna and colleagues have discovered these nurseries occurred in prehistoric times.

In a study published in the journal Scientific Reports, Jamie A. Villafaña from the university’s Institute of Palaeontology describes a fossilized nursery found in Coquimbo, Chile. Researchers were examining a collection of fossilized great white shark teeth between 5 and 2 million years old along the Pacific coast of Chile and Peru when they noticed a disproportionate number of young shark teeth in Coquimbo. There was also a total lack of sexually mature animals' teeth, which suggests the site was used primarily by pups and juveniles as a nursery.

Though modern great whites are known to guard their young in designated areas, the researchers say this is the first example of a paleo-nursery. Because the climate was much warmer when the paleo-nursery was in use, the researchers think these protective environments can deepen our understanding of how great white sharks can survive global warming trends.
