In the early 1960s, NASA rolled up to a US Navy facility in Pennsylvania with one goal in mind: stick its newly-minted astronauts into one of the most extreme centrifuges that has ever been built, and whirl them around really fast to...

From taking your files ransom to foiling uranium enrichment, here are five more computer viruses that you really want to avoid.

Children's toys can help teach kids about colors, shapes, and imagination. But it turns out they've also inspired scientists and engineers for centuries, leading to innovations in medical diagnostics and space travel. So,...

We've seen this done in movies right? Well, why don't spaceships have this technology?

Humans have been using microbes to separate minerals from mud since the middle of the last century, so we know biomining works on earth. But how will these tiny miners work in microgravity?

When first discovered in 2010, the Stuxnet computer worm posed a baffling puzzle. Beyond its sophistication loomed a more troubling mystery: its purpose. Ralph Langner and team helped crack the code that revealed this digital warhead's...

Did you know that centrifugal force isn't really a thing? I mean, it's a thing, it's just not real. In fact, physicists call it a "Fictitious Force." Mind blown yet? To explore this idea further, this week Shini sits down with us to...

Plot often trumps reality when portraying space in movies and, as a result, many films are full of inaccuracies. So how much fiction is actually written into some of our favorite movies? Movies mentioned (and potentially spoiled) in this...

What is metabolomics? Why, it's the study of metabolites of course! In the case of today's researcher, Vasudevan Karanghat, this means using instrumentation and analytical techniques to figure out the concentrations of various compounds...

Changes in acceleration pose an extreme risk for fighter pilots. Find out how they train to avoid blacking-out during flights. Physics - Forces - Learning Points. Fighter pilots undergo training to allow them to cope with G-force....

Orbiting 250 miles above Earth, astronauts aboard the International Space Station explore farther into our solar system and work on thousands of studies that will help us back here on Earth. Join ESA (European Space Agency) astronaut...

NASA’s Goddard Space Flight Center in Greenbelt, Maryland, is one of the few space organizations that can manage a mission from beginning to end: imagine it, build it, test it, launch it and reap the scientific...

A U.S. aerospace company is building a huge centrifuge to launch spacecraft into orbit. <br/>

The centrifugal compressor operates by changing the velocity of gas and converting energy to pressure. In this video we will be discussing the some of the physics in how it operates as well as the basic design, parts and functions.

To prepare for Servicing Mission 4, Hubble components must endure harsh tests at NASA's Goddard Space Flight Center. This feature explores test facilities at Goddard like: launch phase simulator centrifuge, the acoustic test chamber,...

View an interview with Mark C. Hersam of Northwestern University. Double-sided carbon nanotubes are highly prized for their use in solar cells and other applications, but until now creating a supply of just double-sided carbon nanotubes,...

In this video, I talk about the components found in the blood and their functions. We are going to talk about the Complete Blood Count (CBC) test that your doctor orders, red and white blood cells, platelets, and proteins like albumin,...

Centrifuges are machines that can separate mixtures by spinning them very fast! How does this work? This video shows how you can build your own bottle centrifuge to find out.
