VIDEO A new study finds that earlier sea ice melt in the spring and later ice growth in the fall is hurting the feeding and breeding capabilities of polar bear populations all across the the Arctic. Polar bears are among the animals most affected declines in Arctic sea ice. The bears spend their winters and springs roaming and hunting on the ice. Polar bears have evolved mainly to eat seals, which provide the fats and nutrients they need in in the harsh Arctic environment. Bears can’t outswim ..>> view originalHow satellites are helping decode human-caused earthquakes
An international team of researchers recently determined that the 4.8 magnitude earthquake that shook Timpson, Texas in 2012, the largest earthquake ever measured in the state, was caused by fracking and the subsequent wastewater injection process.Using satellite data from the Japanese Advanced Land Observing Satellite (ALOS), the research team observed changes in the height of the ground above several fracking wastewater wells. The study, which was published Thursday in Science, may also hold ..>> view originalSalty Oceans Hiding Underneath Pluto's Heart, Research Suggests
Sep 25, 2016 04:00 AM EDT Pluto may no longer be considered as an actual planet but it has earned a place for itself in the Solar System. With interesting attributes, the icy world is still baffling scientists until today. The latest study suggests that salty oceans may be hiding underneath the frozen surface of Pluto. Pluto's icy "heart" was identified during a flyby to the dwarf planet, and is considered as one of the most important discoveries about the body located at the edge of the Sola..>> view originalRusty patched bumble bee recommended for endangered list - Winston

Causing much anxiety, China's first space lab Tiangong-1 will be falling back to Earth in the second half of 2017. Currently, the "Heavenly Palace" is orbiting at an altitude of 370 kilometers (230 miles). China's official confirmation about the falling space lab came from Wu Ping, deputy director of the manned space engineering office of China. She said the space lab has ended the six years data service in March and "comprehensively fulfilled its historical mission." The official sought to put..>> view original
