30,000 years ago, a ground squirrel burrowed out a spot for itself, about 10 inches in diameter at its widest, where it brought back seeds and other grassy and fruited plants to nibble on. The place where the squirrel chose to make its burrow is now known as Siberia, and the burrow is close to 100 feet below the surface and in a layer of permafrost.

 

The squirrel, of course, is long gone. But tiny roundworms, a type of nematode, that also made their home there have lasted those tens of thousands of years, frozen and immobile. Now, though, scientists in Russia have revived them, making these worms—all of them female worms—the first multicellular organisms to have survived being frozen in Arctic permafrost.

The limits of human existence might not be as limited as we have long thought.

 

 

A person’s risk of death slows and even plateaus above age 105, a new study reports, challenging previous research saying there’s a cutoff point past which the human life span cannot extend.

Longevity pioneers lucky enough to make it past the perilous 70s, 80s and 90s could potentially live well into their 110s, if fortune remains on their side, said senior author Kenneth Wachter, a professor of demography and statistics at the University of California, Berkeley.

Transformative pedagogies, encourage students to be an equal and active participant in their learning. They are not limited to being passive listeners or mere receivers of information, with instructions on how to process the same. Students are expected to consciously understand their learning, the thought processes intertwined with it, while questioning, exploring, and discovering new realms of learning.

"If you’re a six-foot human standing on a paddleboard, it’s just as well you don’t know that a 60-foot, 40-ton humpback whale with 16-foot flippers is surfacing directly beneath you. The only thing more unsettling would be if there were four 60-ft., 40-ton humpback whales with 16-foot flippers doing the same.

 

Just such a don’t-look-down moment played out off the coast of the Hawaiian island of Kauai in 2016. Ordinarily, it would have been the kind of experience that the paddleboarder—who came through unharmed—would have described to his friends with a helpless “You should’ve seen it.” As it happens though, his friends did see it, as did more than 200 million people so far on Facebook, YouTube and uncounted other websites around the world."
