Why some feces float and others sink
A team of researchers at the Mayo Clinic has solved the mystery of why some people find their bowel movements floating while others find theirs sinking to the bottom of the toilet bowl. In their paper published in the journal Scientific Reports, the.....»»
Glaciers rise, fall and melt with tides
Glaciers that extend off the edges of landmasses move much more than scientists anticipated, R. Gadi and colleagues have found. The boundary between the grounded part of a glacier and the point at which the glacier extends past the landmass to float.....»»
Study shows effects of vegetation composition, warming and nitrogen deposition on peatland carbon sink function
Peatlands, which contain about one-third of the global soil carbon stock, are important carbon sinks. Their net carbon uptake is equivalent to ~1% of human fossil fuel emissions or 3%–10% of the current net sink of natural terrestrial ecosystems. H.....»»

Honda is promoting its push toward carbon neutrality in 2050 with a Rose Parade float called 'Keep Dreaming.'.....»»
Even a single negative review can sink a good product, says study
Online retailers have every reason to be concerned about negative reviews, as they severely reduce the appeal of a product. An extensive study by Marton Varga of Bocconi's Department of Marketing and Paulo Albuquerque (INSEAD), recently published in.....»»
New wheat yield analysis method separates disease impact from natural senescence
The yield of wheat crops is influenced by sink strength (grain number and nutrient absorption capacity) and source capacity (photosynthetic tissue efficiency). While sink limitations are widely reported, source limitations due to diseases like septor.....»»
Study finds urban waterfowl are important seed dispersers for native and alien plants
Our park ponds typically hold good numbers of mallards, and urban grassy areas often hold concentrations of geese. In the UK, Canada Geese are an abundant and widespread alien species, well known for fouling parks with their feces......»»
Dung beetle iDNA as an additional tool for biodiversity assessment
Many dung beetles use mammalian feces as a food source and build and relocate dung balls to lay eggs and shelter their larvae. This behavior provides many ecosystem services including nutrient cycling, secondary seed dispersal, soil excavation, and p.....»»
Unique weather phenomenon may have helped Ukraine identify and sink Russian ship Moskva
A pair of radar experts at Swedish Defense Research working with a meteorologist from the Swedish Meteorological and Hydrological Institute has found evidence suggesting that the reason the Ukrainian military was able to spot and sink a distant Russi.....»»

Seagrass decline poses issues for carbon storage projects
Climate change is an ever-pressing concern, with innovative ways to remove excess carbon from the atmosphere a continued focus of scientists. One such carbon sequestration method turns to an unlikely sink—seagrass—a marine flowering plant (angios.....»»
Scientists map loss of groundwater storage around the world
Global water resources are stretched by climate change and human population growth, and farms and cities are increasingly turning to groundwater to fill their needs. Unfortunately, the pumping of groundwater can cause the ground surface above to sink.....»»
China"s "Great Green Wall" boosts carbon sink, study finds
Since 1978, China has been building a "Great Green Wall" of trees and shrubs across its arid and semi-arid regions to combat desertification and improve the environment. Known as the Three-North Afforestation Program (TNAP), it is the largest ecologi.....»»
Even with no brains, jellyfish can learn from their mistakes
In a changed environment, jellyfish change their response to potential collisions. Enlarge / No brain, but still some smarts. (credit: Bielecki, et. al.) They don't have a brain or spinal cord. They float around in a way.....»»
Scientists find the sounds beneath our feet are fingerprints of rock stability
If you could sink through the Earth's crust, you might hear, with a carefully tuned ear, a cacophany of booms and crackles along the way. The fissures, pores, and defects running through rocks are like strings that resonate when pressed and stressed......»»
US Customs officials seize giraffe feces from woman at Minnesota airport
Federal customs agents pooh-poohed the plans of an Iowa woman who wanted to make jewelry from giraffe feces she picked up on a trip to Kenya and brought back to the U.S. in her luggage......»»
New research finds that ancient carbon in rocks releases as much carbon dioxide as the world"s volcanoes
A new study led by the University of Oxford has overturned the view that natural rock weathering acts as a CO2 sink, indicating instead that this can also act as a large CO2 source, rivaling that of volcanoes. The results, published today in the jour.....»»
Gain-of-function allele of HPY1 coordinates source and sink to increase grain yield in rice
Rice is a primary staple crop for over half of the global population, and the continual enhancement of its yield holds significant significance in ensuring world food security. Therefore, achieving sustained increases in rice production has remained.....»»
From seafloor to space: New bacterial proteins shine light on climate and astrobiology
Gigatons of greenhouse gas are trapped under the seafloor, and that's a good thing. Around the coasts of the continents, where slopes sink down into the sea, tiny cages of ice trap methane gas, preventing it from escaping and bubbling up into the atm.....»»
Tuvalu will always be a state, even if underwater, says PM
Tuvalu could be one of the first nations to sink beneath the sea as a result of climate change, but that doesn't mean its statehood is up for discussion, the tiny Pacific archipelago's prime minister said Thursday......»»
