☆ Earth’s core may have been leaking helium for millions of years

They wanted to investigate the rocks that may contain insights about the contents locked within Earth’s core and mantle, the mostly solid layer of Earth’s interior located beneath its surface. Helium inherited from the solar nebula likely became locked in Earth’s core as the planet formed, making the core a reservoir of noble gases. “So, the helium we measured in these rocks would have escaped the core perhaps 100 million years ago or possibly much earlier.”Helium leaking from Earth’s core doesn’t affect our planet or have any negative implications, he said. If so, have fluxes of these elements from the core over (Earth’s) history influenced planetary evolution? I am excited to investigate links between helium and other light elements,” Horton said.

☆ Earth's mysterious core appears to be leaking, leaving scientists baffled

This could suggest the Earth's core is "leaking" helium. The study suggests the Earth's core may be leaking the rare helium, upheaving the belief that the giant ball of molten iron at the center of our planet is sealed away. AdvertisementAdvertisementWhat puzzled scientists in this latest study is just how much ³He was in the Baffin Islands lava olivine rocks. An illustration of Earth's core. AdvertisementAdvertisement"One important question is, assuming helium is leaking out of the core, whether any other elements also escape from the core?

☆ A mysterious Arctic shark that can live for 500 years got lost and ended up swimming in the balmy waters of the Caribbean, scientists say

A shark was found in the Caribbean — thousands of miles away from its usual habitat in the Arctic. The Greenland shark, which has a lifespan of 250 – 500 years, surprised researchers in Belize. When they retrieved their scientific catch, they were astonished to find the ancient Greenland shark. Greenland sharks are primarily scavengers, eating everything (dead or alive), including fish, seals, polar bears, and whales.

☆ Cold weather testing: Airplanes endure punishing extremes

CNN —With extremely cold temperatures gripping much of the United States, travelers may be wondering how their planes are made safe for flying. Their mission was to see how their test plane, a long-range A350 XWB, withstood extreme cold. From cold to hotNew plane models undergo testing under extreme conditions before they're put into service. The cold-weather tests in Canada came only days after the MSN3 test plane completed high-altitude test in Bolivia. This kind of weather has made it an ideal spot to test aircraft.
