Ancient Hawaiian Glaciers Reveal Clues to Global Climate Impacts

Boulders deposited by an ancient glacier that once covered
the summit of Mauna Kea on the island of Hawaii have provided more evidence of the extraordinary power and reach of global change, particularly the slowdown of a North Atlantic Ocean current system that could happen again and continues to be a concern to climate scientists.

Asian spiny frogs are named for the nubby
spines on their chests and arms, which they use to grasp females during mating in swift streams. Kunming Institute of Zoology and University of California, Berkeley, biologists have conducted a genetic analysis of 24 species of spiny frogs and correlated their diversification with the rise of the Himalayas and Tibet. The findings support a theory that India not only uplifted the mountains, but shoved Southeast Asia toward the Pacific.

There isn't a lot of research that links early childhood test scores to earnings as an adult. But new research reveals a surprising finding: Students who learn more in kindergarten earn more as adults. They are also more successful overall.
Harvard University economist John Friedman says he and a group of colleagues found that students who progress during their kindergarten year from attaining an average score on the Stanford Achievement Test to attaining a score in the 60th percentile ...

Oldest Earth Mantle Reservoir Discovered

Researchers have found a primitive Earth mantle reservoir on Baffin Island in the Canadian Arctic. Geologist Matthew Jackson and his colleagues from a multi-institution collaboration report the finding--the first discovery of what may be a primitive Earth mantle--this week in the journal Nature.
The Earth's mantle is a rocky, solid shell that is between the Earth's crust and the outer core, and makes up about 84 percent of the Earth's volume. The mantle is made up of many ...
