Rare Tree Frog Species Likely Extinct After Last Known Living Member Dies At Atlanta Botanical Garden
A rare species of tree frog may now be extinct following the death of its last known living member that lived in captivity. The frog called Toughie died in its enclosure at the Atlanta Botanical Garden. The male amphibian, which is believed to be about 12 years old, was found dead during a routine daily inspection conducted on Sept. 29. "It's a sad day here at the Garden as we mourn the loss of our beloved Rabbs' fringe-limbed tree frog, " the Atlanta Botanical Garden posted on its Facebook pag..>> view originalNew Source Of Greenhouse Gas: How Do Water Reservoirs Accelerate Global Warming?
Electricity generated by dams and reservoirs may not be so "clean" after all, a new report suggests. For decades, scientists have considered hydropower as a cheap but clean source of energy, renewable yearly by rainfall and snow. It is also an alternative to coal, nuclear and gas power plants. However, hydropower isn't all it's cracked up to be: researchers in Washington have discovered that hydroelectricity is actually an "underappreciated source" of greenhouse gases.

Federal authorities added the first bees to the endangered species list Friday, seeking a way to protect several vital pollinators who ensure the survival of many local plants and play an essential role in preserving the food chain.The listing includes seven types of yellow-faced bees native to Hawaii that help to pollinate some of the state’s endangered plants. While human development and interaction with the bees and their habitat has played a destructive role, other insects, including invasi..>> view originalYoshinori Ohsumi of Japan Wins Nobel Prize in Medicine

Credit Akiko Matsushita/Kyodo News, via Associated Press Yoshinori Ohsumi, a Japanese cell biologist, was awarded the Nobel Prize in Physiology or Medicine on Monday for his discoveries on how cells recycle their content, a process known as autophagy.Autophagy, derived from Greek, means “self-eating.”“This concept emerged during the 1960s, when researchers first observed that t..>> view originalWhat spiral 'arms' around a star tell us about planet formation
Spirals can be found throughout nature, from the smallest sea shells to the largest galaxies. As stars from from clouds of gas, the gravitational pull of a star will collapse the gases into a disk around it, often forming spirals in a manner similar to the galactic-scale disk of our own Milky Way.Scientists have observed these stellar spirals before. But the spiral around Elias 2-27 is a little different.Elias 2-27 is a young star, at least a million years old and about half the size of our own..>> view originalThe Tech Ice Hunters Use to Track the Arctic Melt
From about a thousand feet in the air, scientists from Germany’s Alfred Wegener Institute began to lower a torpedo-like device from the underbelly of their plane. The cylindrical instrument would hang from a 200-foot cable and let the team measure the thickness of the Arctic sea ice below. Ice is an important part of Earth’s climate system. As the planet warms and more ice melts away, scientists are scrambling to figure out how the shrinking ice might affect weather patterns world-wide.

Each November, monarch butterflies embark on an incredible cross-country migration that begins in the United States and Canada. Generations of these butterflies travel thousands of miles until they reach Mexico, where they overwinter until it’s time to begin their migration back home in March. The butterflies spend their time in concentrated areas of forest where they form colonies by clinging to the branches of trees, forming beautiful cascading clusters. Monarchs are a truly magnificent speci..>> view original
