If you've ever entertained those questions, you've engaged with some of the most pressing mysteries of physics. And you might want to turn to Instagram - yes, Instagram - for more information. It turns out that the social media network is packed with great science photos, and the granddaddy of all labs, CERN, also runs a behemoth of an Insta feed.

According to Innova Market Insights, a marketing research group of the food-and-beverage industry, just under 5 percent of dietary supplement launches target children. But supplement use among children is much higher.

If you live in California, you may have to answer that question in your lifetime. Los Angeles has a 31% chance within the next 30 years of experiencing a magnitude-7.5 earthquake, according to the U.S. Geological Survey

A cube of uranium. A Nazi plan to build a nuclear bomb. A search for the fate of the remaining pieces of an experiment that might have altered history.

NASA has uploaded hundreds of tracks and podcasts to the sound-sharing platform. The sounds are diverse, fascinating, frequently updated and free of charge.

In October 1900, an enamored Albert Einstein wrote a note to his bride-to-be, Mileva Maric. "I'm so lucky to have found you, a creature who is my equal," he gushed.

A cognitive psychologist, Van der Stigchel is interested in how human brains process visual information. His book is slender but packed with information about how the brain navigates a complex visual world.

As people age, the body changes in all sorts of predictable ways. Joints stiffen. Brains can slow. Wounds take longer to heal. And sleep patterns shift, too. Read here to know if this is healthy.

What do spider webs sound like? If you've never considered the question, don't stress: Scientists and musicians have. They've created an interactive, multimedia performance that lets you tour a spider-spun web that makes otherworldly music.

Google Mars lets you explore the Red Planet without the 140-million-mile journey.

Screening for Mental Health's online screening program gives a brief survey. It then tells you whether your answers are consistent with depression and provides materials to bring to your next doctor's visit and a list of resources.

Janet Jay not RoboCop or Darth Vader. But she shares a similarity with those characters: Her all-too-human body has been upgraded with a machine.

At Houston's Health Museum, visitors can get as close as possible to inhabiting another person's body by putting on skin suits molded from silicone, latex and other materials. "Bodysuits" are part of the museum's new exhibition "Body as a Work of Art: More Than Skin Deep," on view through Jan. 11.
