Opportunity discovers clays favorable to martian biology and sets sail for motherlode of new clues
Now nearly a decade into her planned 3 month only expedition to Mars, NASA's longest living rover Opportunity, struck gold and has just discovered the strongest evidence to date for an environment favorable ...
Study suggests space dust carries water and organic compounds
Researchers from the University of Hawaii-Manoa (UHM) School of Ocean and Earth Science and Technology (SOEST), Lawrence Livermore National Laboratory, Lawrence Berkeley National Laboratory, and University ...
Fossilized conduits suggest water flowed beneath Martian Surface
(Phys.org)—Networks of narrow ridges found in impact craters on Mars appear to be the fossilized remnants of underground cracks through which water once flowed, according to a new analysis by researchers ...
Hormone-mimics in plastic water bottles -- just the tip of the iceberg?
In an analysis1 of commercially available mineral waters, the researchers found evidence of estrogenic compounds leaching out of the plastic packaging into the water. What's more, these chemicals are potent in vivo and result ...
Unprecedented rate and scale of ocean acidification found in the Arctic
Acidification of the Arctic Ocean is occurring faster than projected according to new findings published in the journal PLoS One. The increase in rate is being blamed on rapidly melting sea ice, a proces ...
Wet and mild: Researchers take the temperature of Mars's past
(PhysOrg.com) -- Researchers at the California Institute of Technology (Caltech) have directly determined the surface temperature of early Mars for the first time, providing evidence that's consistent with ...
'Cold' Mars Could Have Harbored Liquid Water
(PhysOrg.com) -- A new NASA study provides further evidence that Martian minerals dissolved in water could have kept that water from freezing, even on a cold, early Mars.
Exposed rocks point to water on ancient Mars
A new discovery of hydrothermally altered carbonate-bearing rocks on Mars points toward habitable environments deep in the martian crust, a Planetary Science Institute researcher said.
Early Mars may not have been hospitable after all: study
Instead of a warm, wet and possibly life-bearing planet as some scientists contend, early Mars may have been a hostile and volatile place with frequent volcanic outbursts, a study said Sunday.
High-speed cameras reveal the complex physics at work as air meets water and glass
When a bubble of air rising through water hits a sheet of glass, it doesn't simply stop—it squishes, rebounds, and rises again, before slowly moving to the barrier. This seemingly simple process actually ...
Out of thin Martian air
A wet Mars is just a memory, but where did the water go?
Surveying Earth's interior with atomic clocks
Ultraprecise portable atomic clocks are on the verge of a breakthrough. An international team lead by scientists from the University of Zurich shows that it may be possible to use the latest generation of ...
Researchers say atomic clocks now good enough to measure Earth's geoid
New evidence found for the oldest oxygen-breathing life on land
New University of Alberta research shows the first evidence that oxygen-breathing bacteria occupied and thrived on land 100 million years earlier than previously thought.
