Watch a Spider Weave An Intricate Web in Less Than 5 Minutes

Spiders are arguably nature’s finest fiber artists. Inside those hairy bodies is a highly concentrated liquid that produces multiple types of silken threads made from different protein sequences. These silks are used to make webs, create egg sacs, build tiny protective shelters, catch prey, and even form tiny parachutes that allow some arachnids to sail through the sky.

When it comes to webs, spiders weave many different types: triangular webs, webs with a funnel at one end, bowl or dome-shaped webs, and webs resembling flat silken sheets, just to name a few. Some of the threads in these webs are stretchy—to absorb the impact of flying insects—whereas others keep a web strong, moist, and bacteria- or fungi-free.

If you loved E.B. White's 1952 children's novel Charlotte’s Web as a kid, you’re likely most familiar with the circular, wagon-wheel-like creations made by orb-weaver spiders like the book’s titular character. In the video below—filmed by BBC Earth and spotted by The Kid Should See This—you can watch an orb-weaver spider create an intricate web, thread by thread, in less than five minutes.

For the First Time Ever, a Mammal Has Been Declared Extinct Due to Climate Change

An Australian rat-like rodent called the Bramble Cay melomys is the first known mammal wiped out by manmade climate change, The Hill reports. The now-extinct animal (Melomys rubicola) lived on the tiny, uninhabited island of Bramble Cay in the Great Barrier Reef. Despite exhaustive efforts to track down the melomys over seven years, no signs of the rodent could be found, and in 2016, Queensland’s state government declared the animal extinct.

These fears were confirmed when news broke this week that the national government had quietly changed the rodent’s classification from endangered to extinct. Meanwhile, the status of a fruit bat called the spectacled flying-fox was changed from vulnerable to endangered after a recent heatwave in north Queensland, which dealt another blow to a population that had already been cut in half over the last decade.

As for the Bramble Cay melomys, its demise can be attributed to rising sea levels, storm surges, and other weather events that have worsened due to climate change. According to The Revelator, the tides destroyed about 97 percent of the island’s vegetation, which was the rodent’s only food source.

Leeanne Enoch, Queensland's Minister for Environment and the Great Barrier Reef, told The Sydney Morning Herald that the latest animal extinction is evidence “we are living the real effects of climate change right now.”

In a 2018 study commissioned by the World Wildlife Fund, researchers found that up to half of the 80,000 plant and animal species that reside in 35 of the world’s most diverse areas could become extinct by the turn of the century because of climate change.

For some species, it’s already too late. A Hawaiian bird called the poo-uli (or black-faced honeycreeper) was declared extinct last year, largely due to diseases carried by mosquitoes, which thrive in warmer climates. For other endangered species in the U.S.—like the black-footed ferret, red wolf, and rusty patched bumble bee—there might still be time to step in and protect them.

A Fort Hood Mule With 12 Years of Army Experience Is Looking for a Forever Home

Attention, animal lovers: A mule in Fort Hood, Texas with more than a decade of U.S. Army experience is up for adoption. Tina the Army mule has been a part of the Fort Hood military base's 1st Cavalry Division Horse Detachment for most of her life, and now KWTX reports that she needs a place to spend her retirement.

Foaled in 1999, the Fort Hood 1st Cavalry adopted Tina in 2006. Since then, she has assisted in parades, weapons demonstrations, cavalry charges, and color guards for the division. She has experience pulling an M1878 Escort wagon in a harness as well as standing by calmly for ceremonies.

She worked as a draft mule until 2018, and now that she's retiring, Fort Hood officials are looking to find her a forever home. Tina has no health problems or dietary restrictions and enjoys eating Coastal Bermuda hay and pasture grass. Her sister Dolly, who died of bone cancer in 2018, was the only mule she's ever been paired with. Though Tina can perform light solo work, her new owners should be cautious about pairing her with another mule.

If you're interested in making Tina a part of your family, Fort Hood would like to hear from you. You can contact the current owners by emailing your request along with any questions to 1CDHorseCavalryDetachment@gmail.com by March 7. Once your inquiry is received, you'll be sent an application packet with instructions on how to proceed.
