A radiating beauty on Mars
(Phys.org) —Exceptional structures deposited and shaped by water and winds adorn these interlocking craters and sculpt radiating patterns in the sands of Mars.
Research trio offer new explanation for breakup of Larsen B Ice Shelf
Team suggests complex relationship between phosphorus levels and nitrogen removal in lakes
In the land of 10,000 lakes, one lake has been the starting place for research with implications for big lakes around the world. According to a study published online this week in Science, University of Min ...
Cold, salty and promiscuous: Gene-shuffling microbes dominate Antarctica's Deep Lake
Sequestered in Antarctica's Vestfold Hills, Deep Lake became isolated from the ocean 3,500 years ago by the Antarctic continent rising, resulting in a saltwater ecosystem that remains liquid in extreme cold, ...
Small isolated populations pose a threat to new dolphin species
Victoria's iconic new dolphin species, the Burrunan dolphin, is at risk due to its small and isolated populations, according to the first study investigating the dolphin's population using DNA.
Life found in the sediments of an Antarctic subglacial lake for the first time
Evidence of diverse life forms dating back nearly a hundred thousand years has been found in subglacial lake sediments by a group of British scientists.
Study examines climate change effects on crop mix shift, transportation
(Phys.org) —Drought conditions in Texas and throughout the U.S. the past decade have not only caused crops to fail, but farmers have had to alter the mix of commodities planted to better adapt to a changing ...
In subglacial lake, surprising life goes on: Team identifies species in most inhospitable realm
Lake Vostok, buried under a glacier in Antarctica, is so dark, deep and cold that scientists had considered it a possible model for other planets, a place where nothing could live.
Researchers date oldest known petroglyphs in North America
A new high-tech analysis led by a University of Colorado Boulder researcher shows the oldest known petroglyphs in North America, which are cut into several boulders in western Nevada, date to at least 10,500 ...
Climate-cooling arctic lakes soak up greenhouse gases, study finds
New University of Alaska Fairbanks research indicates that arctic thermokarst lakes stabilize climate change by storing more greenhouse gases than they emit into the atmosphere.
Fish forced into the 'foraging arena' when lakes lose their trees
(Phys.org) —In attempts to predict what climate change will mean for life in lakes, scientists have mainly focused on two things: the temperature of the water and the amount of oxygen dissolved in it.
Competition breeds new fish species, study finds
Competition may play an important role during the evolution of new species, but empirical evidence for this is scarce, despite being implicit in Charles Darwin's work and support from theoretical studies.
US state home to new mega-warehouse for data
The new billion-dollar epicenter for fighting global cyberthreats sits just south of Salt Lake City, tucked away on a militia base at the foot of snow-capped mountains. The long, squat buildings are filled ...
Mapping the benefits of our ecosystems
We rely on our physical environment for many things – clean water, land for crops or pastures, storm water absorption, and recreation, among others. Yet it has been challenging to figure out how to sustain the many benefits ...
