NEW YORK — Neon green, vivid orange, striped and spotted — the frogs are back! An exhibit featuring live frogs from around the world is returning to the American Museum of Natural History here in New York.
The oldest ape and Old World monkey fossils have been unearthed in a riverbed in Tanzania, a new study reports.
Researchers found a tooth from the newfound species Nsungwepithecus gunnelli, the oldest member of the primate group that contains Old World monkeys (cercopithecoids). The team also found a jawbone from the newfound species Rukwapithecus fleaglei, an early member of the hominoids, the group containing the great apes (gorillas, chimpanzees, bonobos, orangutans and humans) and lesser apes (gibbons).
The world's glaciers lost 260 gigatons of water each year between 2003 and 2009, making these rivers of ice responsible for almost a third of sea-level rise in that time, new research finds.
The study, to appear tomorrow (May 17) in the journal Science, used multiple methods to pin down estimates of how much ice is lost from glaciers. The results suggest that on-the-ground measurements yield estimates that are too extreme, but some satellite methods don't go far enough.
In Alaska, where the winter runs colder, the sun shines longer and the mountains rise taller than any other state, the Land of the Midnight Sun can claim another superlative: The biggest and strangest maars ever found on Earth.
Maars are craters left behind after violent volcanic steam explosions, sparked when rising magma runs into groundwater, which then blows up like a bomb.
An overachieving sunspot on the surface of the sun unleashed its fourth major solar flare in two days late Tuesday (May 14), a solar storm that may deal Earth a glancing blow, space weather experts say.
The active sunspot AR1748 roared to life Tuesday night releasing an X-class solar flare — the strongest type the sun can experience — that peaked at 9:48 p.m. EDT (0148 May 15 GMT), according to NOAA's Space Weather Prediction Center in Boulder, Colo. The flare came after a relative lull in activity from sunspot AR1748, which fired off three monster X-class solar flares within a 24-hour period between Sunday and Monday.
A powerful new ultraviolet laser that fires into the night sky is helping scientists take their most detailed look yet at a distant star cluster.
A team of astronomers at the Southern Observatory for Astrophysical Research (SOAR) and the Cerro Tololo Inter-American Observatory (CTIO) in Cerro Pachon in Chile used an instrument called SOAR Adaptive Module, or simply SAM, to peer deep inside the crowded NGC 6496 cluster to understand how its stars evolved.
Collectors prize the copper mineral linarite for its intense blue color, but specimens with crystals large enough to truly show off this hue are rare.…Read More »
Linarite, which also contains lead, typically shows up in the form of microcrystals, "little sparkling blue things that coat other stuff," said Jim Walker, a director of the nature and science department at the auction house Heritage Auctions. "You don't really get any idea what the crystal form is, because their sizes are fractions of a millimeter."
Charles Darwin sparked more than one controversy over the natural progression of life. One such case involved the evolution of coral atolls, the ring-shaped…Read More »
coral reefs that surround submerged tropical islands.
Coral reefs are actually huge colonies of tiny animals that need sunlight to grow. After seeing a reef encircling Moorea, near Tahiti, Darwin came up with his theory that coral atolls grow as reefs stretch toward sunlight while ocean islands slowly sink beneath the sea surface. (Cooling ocean crust, combined with the weight of massive islands, causes the islands to sink.)
As weather warms up off the coast of France, blooms of plankton have once again begun to form, creating a beautiful, multicolored swirl visible from space.
NASA's Terra and Aqua satellites acquired these images of the colorful blooms on April 20 and May 4, according to the NASA Earth Observatory. On the later date, a noticeably larger bloom occurred, fueled by nutrient runoff from French rivers and warmer temperatures in the Bay of Biscay.
