After his wife of 50 years died, he found a secret letter she had hidden from him for decades

The letter was sent in 1959 and she never let him see it.

Tony Trapani and his wife were married for 50 years despite the heartache of being unable to have children. "She wanted children,” Trapani told Fox 17. "She couldn't have any. She tried and tried." Even though they endured the pain of infertility, Tony's love for his wife never wavered and he cherished every moment they spent together.

After his wife passed away when Tony was 81 years old, he undertook the heartbreaking task of sorting out all of her belongings. That’s when he stumbled upon a carefully concealed letter in a filing cabinet hidden for over half a century.

The letter was addressed to Tony and dated March 1959, but this was the first time he had seen it. His wife must have opened it, read it and hid it from him. The letter came from Shirley Childress, a woman Tony had once been close with before his marriage. She reached out, reminiscing about their past and revealing a secret that would change Tony's world forever.

Scientists have finally figured out how whales are able to 'sing' underwater

The physical mechanism they use has been a mystery until now.

Whales are notoriously difficult to study because of their size and the environment they require, which is why the mechanism behind whale song has remained a mystery for so long. It's not like scientists can just pluck a whale out of the ocean and stick it in an x-ray machine while it's singing to see what's happening inside its body to create the sound. Scientists had theories, but no one really knew how baleen whales sing.

Now, thanks to researchers at the University of Denmark, that mystery has been solved.

Body language expert reveals hack that shows the 'true emotion' on someone's face

There's one thing they can't hide.

There are countless situations in life where we have to figure out how someone really feels, but they have a good poker face that keeps their feelings well-hidden. According to body language expert Terry Vaughan even the most deceptive people in the world have a tell: the left and right sides of their face don’t usually match.

So, which side do we believe? Vaughan says the left.

“The reason this is a powerful hack is because the left side of the face is more likely to reveal the ‘true emotion’ or the ‘dominant’ emotion if there’s a mix,” Vaughan says. The reason? “The right hemisphere of our brain does more heavy lifting in dealing with processing emotions. The left hemisphere…is a little more analytical or ‘strategic.’”

Two guys captured the speed of light on camera at 10 trillion frames per second

"The light is moving a million times faster than a bullet.”

Gavin Free and Daniel Gruchy aka the “Slow Mo guys,” have filmed all sorts of things in, you guessed it, slow motion—everything from popcorn makers to giant water balloons to even tattoo guns. Each of their videos feels a bit like “Mythbusters.” Just a couple of guys making science super fun.

One of the Slow Mo Guys’ most popular videos, with a total of 41 million views on Youtube to date, features thefastest thing known to man: light.
