This is what it's like to be a paleontologist out in the field, from waking at dawn's first light, to digging in the rocks, to wrapping or jacketing finds, to gathering around the campfire, exhausted and covered with ...

It’s Okay to Be Smart – The Cycle: Carbon and Oxygen and You

From PBS Digital Studios and Joe Hanson of It's Okay to Be Smart, this is The Cycle: Carbon and Oxygen and You, a visualized explanation for what happens when we breathe. And here it is explained: via It's Oka...

Paralyzed Woman Controls Robotic Arm With Thoughts

When Cathy Hutchinson controlled a robotic arm using a small sensor planted in her brain, it was a remarkable breakthrough in neurobiology and computer science. The sensor would recognize patterns or signals from her ...

Watch a time lapse sunset through a solar telescope

Seeing the sun set can already be a breathtaking experience, but observing the sun with a solar telescope reveals incredible details — such as sunspots and solar filaments — that we could never safely see ...

Spiders Tune Their Webs Like A Guitar

Much more than just a net to catch prey, spider webs can transmit lots of information about what has been caught or what might be visiting. Oxford researchers have recently discovered that the strands of silk vibrate ...

Collecting the deep sea animals of Monterey Submarine Canyon
