Today, we all get 1 extra second - a leap second - which is added to our clocks to adjust for Earth's rotation. The time morsel will be added tonight at 23:59:59 - so make sure to enjoy that 61-second minute!

Believe it or not, there are a few cultures in the world where back pain hardly exists. One indigenous tribe in central India reported essentially none. And the discs in their backs showed little signs of degeneration as people aged.
An acupuncturist in Palo Alto, Calif., Esther Gokhale, thinks she has figured out why. She has traveled around the world studying cultures with low rates of back pain — how they stand, sit and walk. Now she's sharing their secrets with back pain sufferers across the U.S.
Gokhale took photos and videos of people who walked with water buckets on their heads, collected firewood or sat on the ground weaving, for hours.
"I have a picture in my book of these two women who spend seven to nine hours everyday, bent over, gathering water chestnuts," Gokhale says. "They're quite old. But the truth is they don't have a back pain."
She tried to figure out what all these different people had in common. The first thing that popped out was the shape of their spines. "They have this regal posture, and it's very compelling."
Could it be the ancients might have worked harder, died younger, but suffered less than we modern humans?

What color is Pluto? NASA's New Horizons spacecraft is closing in on it, and new images are revealing something completely different.
According to NASA, New Horizons' principal investigator, Alan Stern of the Southwest Research Institute, says scientists have known about Pluto's reddish hues for decades, but because images have never been taken from this close, they didn't know for sure. But thanks to the maps developed from New Horizons' data, recorded from roughly 7.8 million miles away between July 1 and July 3, researchers are now able to see the real detail of its coloring and texture.
As it turns out, the sneaky thing is red. Or, at least, reddish brown, similar to Mars. But while the coloring on Mars is from iron oxide, Pluto likely has a different agent. According to NASA, the reddish color is likely caused by hydrocarbon molecules that are formed when cosmic rays and solar ultraviolet light interact with methane in Pluto's atmosphere and on its surface."

6 oz can tomato paste
1/4 cup honey (or agave)
1/2 cup white vinegar
1/4 cup water
3/4 tsp salt
1/4 tsp onion powder
1/8 tsp garlic powder
Combine all the ingredients in a medium saucepan over medium heat; whisk until smooth.
When it comes to a boil, reduce heat to low and simmer for 20 minutes, stirring often.
Remove from heat and cover until cool. Chill and store refrigerated in a covered container.

"A team of scientists and engineers at The University of Texas at Austin has identified the first sensor of the Earth's magnetic field in an animal, finding in the brain of a tiny worm a big clue to a long-held mystery about how animals' internal compasses work.
Animals as diverse as migrating geese, sea turtles and wolves are known to navigate using the Earth's magnetic field. But until now, no one has pinpointed quite how they do it. The sensor, found in worms called C. elegans, is a microscopic structure at the end of a neuron that other animals probably share, given similarities in brain structure across species. The sensor looks like a nano-scale TV antenna, and the worms use it to navigate underground.
"Chances are that the same molecules will be used by cuter animals like butterflies and birds," said Jon Pierce-Shimomura, assistant professor of neuroscience in the College of Natural Sciences and member of the research team. "This gives us a first foothold in understanding magnetosensation in other animals."
The researchers discovered that hungry worms in gelatin-filled tubes tend to move down, a strategy they might use when searching for food.
When the researchers brought worms into the lab from other parts of the world, the worms didn't all move down. Depending on where they were from—Hawaii, England or Australia, for example—they moved at a precise angle to the magnetic field that would have corresponded to down if they had been back home. For instance, Australian worms moved upward in tubes. The magnetic field's orientation varies from spot to spot on Earth, and each worm's magnetic field sensor system is finely tuned to its local environment, allowing it to tell up from down.
The research is published today in the journal eLife."
