Walrus Tricks - WARNING: May Cause You To Develop Terminal Cuteness Overload

------
I don't often cover biology, and this video COULD be scientific, with the obvious extensive background information involved.  For now, however, simply enjoy

Real Time Travel - Einstein Discovered Time Dilation

------
Einstein's Special Relativity included the discovery that physical speed slows time.  The first definitive experiment was done very simply.  There were two synced atomic clocks.  One was stationary.  The other was sent in a jet that flew around the world and back.  It turned out that yes, there was a time discrepancy after all.  THEN people really started to pay attention.

This video talks a bit about REAL time travel, the proven kind, which is actually called Time Dilation.

DARPA Puts Out Flames With Speakers

It almost seems like this news story was tailored just for me!

FIRE

AUDIO

Yes, I'll take it, thank you.

DARPA started the Instant Fire Suppression Program (IFS) in 2008.  Round 2, which we'll see in a second, uses audio; but the first method out of this program was a "flame-suppression system that used a handheld electrode to suppress small methane gas and liquid fuel fires."

The second phase, using acoustics, was developed in 2011.
This video below shows something new and quite amazing. The exact description of what's going on here is very hard to reword, so here is their explanation:

"First, the acoustic field increases the air velocity. As the velocity goes up, the flame boundary layer, where combustion occurs, thins, making it easier to disrupt the flame. Second, by disturbing the pool surface, the acoustic field leads to higher fuel vaporization, which widens the flame, but also drops the overall flame temperature. As the same amount of heat is spread over a larger area, combustion is disrupted."

The Protostar V1647 Orionis

There's brand new coverage out of NASA Astrophysics on x-rays and magnetic hijinx from a low mass star in its "toddler phase."  This star, V1647 Orionis, is in a beautiful and newly found nebula, M78.
