Researchers say atomic clocks now good enough to measure Earth's geoid
Study of clays suggests watery Mars underground
(PhysOrg.com) -- A new NASA study suggests if life ever existed on Mars, the longest lasting habitats were most likely below the Red Planet's surface.
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.
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 ...
Study confirms water quality in glass and plastic bottles
Bottled water sold in Spain is practically free of constituents given off by plastic packaging or glass bottle lids. They are only detected in some cases, albeit in quantities much lower than limits found ...
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 ...
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 ...
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 ...
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 ...
Out of thin Martian air
A wet Mars is just a memory, but where did the water go?
Guyana suspends gold, diamond mining permits
The South American country of Guyana said it had suspended the granting of new permits to mine for gold and diamonds in rivers because of concerns over widespread pollution.
Patience pays off with methanol for uranium bioremediation
The legacy of nuclear weapons and nuclear energy development has left ground water and sediment at dozens of sites across the United States and many more around the world contaminated with uranium. The uranium is transported ...
Drilling study finds faults after earthquakes heal faster than previously thought
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.
