Your heart beats more than 100,000 times a day. In just a minute, it pumps over five liters of blood throughout your body. But unlike skin and bones, the heart has a limited ability to repair itself. So if this organ is severely damaged, there’s often only one medical solution: replacing it. Dig into the […]
From Nature: Roboticists have designed all sorts of jumping robots over the years, and many of them have been inspired by biology. But, as diverse as the natural world is, evolution hasn’t cracked every option. Now a team of researchers has investigated the differences between biological and mechanical jumpers – and have managed to design […]
Something’s up with the data coming from Voyager 1. NASA says such an unexplained issue is not unexpected given the craft’s age and circumstances. Launched in 1977, Voyager entered the interstellar plasma in 2015. That made it the first man-made object to leave our solar system and no longer be significantly affected by the sun. […]

From SciShow: You might want a really sturdy umbrella to dig into this video, because we’re discussing 5 animals that have a tendency to rain down from the sky and the reasons we think this might be happening! [SciShow]
You know how you somehow end up getting smoke in your eyes wherever you stand around a bonfire? Well, it turns out that’s not a curse! It’s much more easily explained with physics. [SciShow]
Researchers say they have proof-of-concept of an approach that could dramatically speed up computer processing. As seems to be the case with 90 percent of technological advances these days, it involves graphene. The University of Rochester researchers were trying to find a faster way to use logic gates, the physical component in a processor that […]
A war has been going on for billions of years that breeds well armed monsters who struggle with other monsters for survival. Having no particular interest in us, most of them are relatively harmless, as our immune systems deal with their weapons handily. But there are exceptions. Naegleria fowleri is an amoeba that not only […]
The Bermuda Institute of Ocean Sciences presents “The Egg”, a video short from the 2011 BIOS Explorer program’s “Water Moves” series. Watch what happens when we crack open a raw egg 60 feet (20 meters) below the surface! [BIOSstation]
Have you ever heard ‘evolution’ dismissed as ‘just a theory’? Is a scientific theory no different to the theory that Elvis is still alive? Jim Al-Khalili puts the record straight. There’s an important difference between a scientific theory and the fanciful theories of an imaginative raconteur, and this quirk of semantics can lead to an […]
