New group seeks to timeline the Anthropocene—when humans became the dominant force on Earth
Colorful life-form catalog will help discern if we are alone
While looking for life on planets beyond our own solar system, a group of international scientists has created a colorful catalog containing reflection signatures of Earth life forms that might be found on ...
Two lakes beneath the ice in Greenland, gone within weeks
Researchers who are building the highest-resolution map of the Greenland Ice Sheet to date have made a surprising discovery: two lakes of meltwater that pooled beneath the ice and rapidly drained away.
Meteorite material born in molten spray as embryo planets collided
Asteroids may be a byproduct of planet formation rather than planetary building blocks, according to a recent paper in Nature.
Two-faced fish clue that our ancestors 'weren't shark-like'
An investigation of a 415-million-year-old fish skull strongly suggests that the last common ancestor of all jawed vertebrates, including humans, was not very shark-like. It adds further weight to the growing ...
Bridgmanite: World's most abundant mineral finally named
Researchers offer 'proof' that oxygen is the only light element in the Earth's core
Researchers find carbon reactions with basalt can form carbonate minerals faster than thought
Evidence found for granite on Mars
Researchers now have stronger evidence of granite on Mars and a new theory for how the granite – an igneous rock common on Earth—could have formed there, according to a new study. The findings suggest ...
Scientists discover cosmic factory for making building blocks of life
Scientists have discovered a 'cosmic factory' for producing the building blocks of life, amino acids, in research published today in the journal Nature Geoscience.
Analysis of Sutter's Mill fragments reveals organic compounds not seen in other meteorites
Climate change occurring 10 times faster than at any time in past 65 million years
The planet is undergoing one of the largest changes in climate since the dinosaurs went extinct. But what might be even more troubling for humans, plants and animals is the speed of the change. Stanford climate ...
Natural affinities—unrecognized until now—may have set stage for life to ignite
The chemical components crucial to the start of life on Earth may have primed and protected each other in never-before-realized ways, according to new research led by University of Washington scientists.
A stepping-stone for oxygen on Earth: Researchers find evidence of an early manganese-oxidizing photosystem
(Phys.org) —For most terrestrial life on Earth, oxygen is necessary for survival. But the planet's atmosphere did not always contain this life-sustaining substance, and one of science's greatest mysteries ...
