Watch Christmas Island’s Annual Crab Migration on Google Street View

Every year, the 45 million or so red crabs on the remote Australian territory of Christmas Island migrate en masse from their forest burrows down to the ocean to mate, and so the female crabs can release their eggs into the sea to hatch. The migration starts during the fall, and the number of crabs on the beach often peaks in December. This year, you don’t have to be on Christmas Island to witness the spectacular crustacean event, as New Atlas reports. You can see it on Google Street View.

Watching the sheer density of crabs scuttling across roads, boardwalks, and beaches is a rare visual treat. According to the Google blog, this year’s crabtacular finale is forecasted for December 16, and Parks Australia crab expert Alasdair Grigg will be there with the Street View Trekker to capture it. That is likely to be the day when crab populations on the beaches will be at their peak, giving you the best view of the action.

Google Street View is already a repository for a number of armchair travel experiences. You can digitally explore remote locations in Antarctica, recreations of ancient cities, and even the International Space Station. You can essentially see the whole world without ever logging off your computer.

Sadly, because Street View isn’t live, you won’t be able to see the migration as it happens. The image collection won’t be available until sometime in early 2018. But it’ll be worth the wait, we promise. For a sneak preview, watch Parks Australia’s video of the 2012 event here.

Treat Your Very Good Dog to An Adorable Hawaiian Shirt This Summer

This summer, treat your very good doggo to a very stylish Hawaiian polo shirt—because dogs are people, too.

The shirt, made by Expawlorer and available through Amazon, features a vibrant Hawaiian island scene that will surely highlight the sparkle of adventure in your dog’s eyes and remind you that they deserve an extra belly rub for staying on top of seasonal trends.

It’s made from a natural cotton that will help keep your dog cool beneath the heat of the blistering summer sun, and the Velcro fastener on the front of the shirt will ensure a stress-free dressing experience (for both of you).

Does your dog have an unparalleled penchant for making messes? Fret not: The shirt is machine washable and can be thrown in the dryer, too.

Prices start at $12, and you can purchase it in sizes small, medium, large, and extra large. According to the product description, it fits small and medium-sized dogs best; one reviewer notes that the extra large is snug on their 60-pound dog. If the petite sizing prompts you to wonder, “Would this fit my cat?,” the answer is yes. The small size is designed for pets with a 10-inch neck circumference, which would work for the average cat, though it may be a bit loose on smaller kitties. (“Would my cat let me put this on them?” is an entirely different question that only your cat can answer.)

The Hawaiian shirt is much more than a bold and festive fashion statement—its rich history dates back to the 1920s, and the look has been embraced by a variety of human celebrities, including Frank Sinatra and Elvis Presley.

However, if the “life of the party” connotation of the Hawaiian shirt doesn’t quite fit the personality of your pet, here are some other options.

Female Lab Rats Are the Victims of Gender Bias, Too

Sexism in the workplace isn’t limited to humans. Because neuroscientists presumed that hormonal fluctuations in female lab rats would affect their test results, they have mainly stuck to studying male lab rats. But they may not be getting the whole story, reports Bethany Brookshire at Science News.

Female lab rats do indeed have hormonal surges that affect their behavior—but so do males. Previous research has shown that females consume more cocaine when in heat (in other words, with higher estrogen levels) than at other times. But males with low or high testosterone performed poorly on memory tests.

It’s not just the hormones and their effects that differ between the sexes—it’s also the timeframe for hormonal surges. Behavioral neuroendocrinologist Irving Zucker, who detailed these differences in a 2017 study [PDF] in Biology of Sex Differences, tells Science News that females’ hormones vary more over a few days, while males’ vary more over the course of a single day.

There are also differences between the sexes that have nothing to do with hormones at all. In a 2015 study in eLife, Rebecca Shansky, a neuroscientist at Northeastern University, showed female and male rats a tone or light followed by a (harmless) shock to the feet. While all of the rats first learned to freeze after the signal, fearing the shock, some of the females responded to subsequent signals by racing around the cage—for no obvious hormonal reason. Shansky concluded that female rats may learn to process fear differently than males, suggesting that equality of the sexes among lab rats (at least in terms of studying them) can lead to more insightful results.

Plus, if male and female rats behave differently in a given situation, it’s possible that male and female humans would, too. (Perhaps unsurprisingly, human females have also frequently been excluded from clinical trials, including several important long-running studies on aging and other issues.)

And if you’re starting to feel like rats deserve more credit than you’ve previously given them, check out these other impressive rat facts.
