What saved the West Antarctic Ice Sheet 10,000 years ago will not save it...
The retreat of the West Antarctic ice masses after the last Ice Age was reversed surprisingly about 10,000 years ago, scientists found. The reason...
True origin of ancient turquoise
New research overturns more than a century of claims that the source of turquoise used and revered by ancient civilizations in Mexico, such as...
Ocean waves following sea ice loss trigger Antarctic ice shelf collapse
Storm-driven ocean swells have triggered the catastrophic disintegration of Antarctic ice shelves in recent decades, according to new research published in Nature today.
Plants open their pores and scientists strike gold
Plants containing the element gold are already widely known. The flowering perennial plant alfafa, for example, has been cultivated by scientists to contain pure...
Endocrine-disrupting pesticides impair frog reproduction
In a new study, researchers have investigated how the endocrine-disrupting substance linuron affects reproduction in the West African clawed frog, Xenopus tropicalis. The scientists...
Decades of satellite monitoring reveal Antarctic ice loss
