For some, watching slime can even provoke feelings of relaxation.Here are five things about snot that you probably didn’t know.1.

If you drove on the winding road up the Chilean Andes, you’d spot the white specks of distant telescopes peppering the hills.

Vents taller than a garage door let in air or shut out desert dust. Though the enclosure stands 22 stories tall, it houses no humans. Instead, when the building splits open each night, you’ll see seven o ...read more

Humanity’s early ancestors started dabbling with bipedalism — walking on two legs — as much as 6 to 7 million years ago. It took a while to find our evolutionary footing, but by 3 million years later, the fossil record shows that hominins were pretty well committed to being upstanding.Walking on two legs was literally a great step forward for us. Bipedal locomotion is far more energy-efficient than using both arms and legs to propel us forward, as many primates still do. Conserving energy ...read more
You don’t need to go on a safari to see wild creatures in their natural habitats. There are a number of scientific studies of wild creatures that depend on the eyes of observers just like you.Take part to be transported (virtually) to ecosystems around the world through images and videos (sometimes even livestreams!) where you can make observations that scientists need. Find sharks, iguanas, birds and more with the projects below!Cheers,The SciStarter TeamCredit: Project SIARCProject SIARC (Sh ...read more
