Time is a huge impediment when it comes to working together to halt the effects of climate change, new research suggests.
A study published today in the journal Nature Climate Change reveals that groups cooperate less for climate change mitigation when the rewards of cooperation lay in the future, especially if they stretch into future generations.
Boulder, Colo., USA – New article postings for Geology cover glacial erosion and glacial slip; the work of marine organisms in changing the face of Earth; collisional shortening in the Central Alps; changes in sediment transport in Taiwan after typhoon Morakot in 2009; a new type of iron formation, dubbed "fluvial iron formation"; kimberlites in South Africa; using fossil marine plankton records in 70-million-year-old sediments as indicators of sea ice formation and retreat; and Greenland Ice Sheet behavior.
WASHINGTON D.C. Oct. 18, 2013 -- Plasmas are a soup of charged particles in an electric field, and are normally found in stars and lightning bolts. With the use of high voltage equipment, very small plasmas can be used to manipulate fluid flows. In recent years, the development of devices known as plasma actuators has advanced the promise of controlling flows in new ways that increase lift, reduce drag and improve aerodynamic efficiencies -- advances that may lead to safer, more efficient and more quiet land and air vehicles in the near future.
WASHINGTON D.C. Oct. 18, 2013 -- As anyone who has ever consumed bacteria-contaminated food and experienced "food poisoning" can tell you, it's a miserable experience. Yet it's an all-too-common one, with foodborne illnesses making 1 in 6 Americans -- or 48 million people -- sick each year. Of these people sickened, 128,000 end up in the hospital, according to the Centers for Disease Control and Prevention, while 3,000 die.
COLUMBIA, Mo. – Meteorologists often use information about warm and cold fronts to determine whether a tornado will occur in a particular area. Now, a University of Missouri researcher has found that the temperature of the Pacific Ocean could help scientists predict the type and location of tornado activity in the U.S.
An international team of scientists has provided proof of a key feature of quantum physics – Heisenberg's error-disturbance relation - more than 80 years after it was first suggested.
One of the basic concepts in the world of quantum mechanics is that it is impossible to observe physical objects without affecting them in a significant way; there can be no measurement without disturbance.
In a human-dominated world that contains only little "historical" nature, the term ecosystem can no longer be a synonym for unspoilt nature. The term "novel ecosystems" was coined a few years ago to describe disturbed ecosystems, in which biodiversity has been significantly altered as the result of human intervention. "In our new conservation framework we argue that this strict distinction between historic and novel ecosystems should be reconsidered to aid conservation", pollination biologist Dr. Christopher Kaiser-Bunbury describes the approach, which is not without controversy.
Snow storms, ice and glaciers - these are the usual images we associate with the Antarctic. But at the same time it is also a region of fire: the Antarctic continent and surrounding waters are dotted with volcanoes - some of them still active and others extinct for quite some time. The Marie Byrd Seamounts in the Amundsen Sea are in the latter group. Their summit plateaus are today at depths of 2400-1600 meters. Because they are very difficult to reach with conventional research vessels, they have hardly been explored, even though the Marie Byrd Seamounts are fascinating formations.
MADISON – When it comes to economic growth and environmental impacts, it can seem like Newton's third law of motion is the rule — for every action, there is an equal and opposite reaction — and that in most cases, the economy prospers and the environment suffers.
Enhanced growth of Earth's leafy greens during the 20th century has significantly slowed the planet's transition to being red-hot, according to the first study to specify the extent to which plants have prevented climate change since pre-industrial times. Researchers based at Princeton University found that land ecosystems have kept the planet cooler by absorbing billions of tons of carbon, especially during the past 60 years.
For decades, it was thought that our skeleton and all its characteristic bony tissues originated in the predators, known as 'conodonts'. However new research, led by the University of Bristol and published today in Nature, shows that they were evolutionary copy-cats who evolved tooth-like structures and tissues independently of other vertebrates. The origin of our skeleton is to be found in the armour of our mud-slurping ancestors who evolved bony armour to protect themselves from such predators.
URBANA, Ill. – Haitian teens, especially those who live in the country's rural areas, are among the poorest persons in the Western Hemisphere, but they are rich in their family relationships and strongly rooted in their own culture, a University of Illinois study finds.
Animal populations can have a far more significant impact on carbon storage and exchange in regional ecosystems than is typically recognized by global carbon models, according to a new paper authored by researchers at the Yale School of Forestry & Environmental Studies (F&ES).
Alexandria, VA –The majority of bachelor's and doctoral graduates did not participate in an internship experience during their postsecondary career, whereas the majority of master's graduates did have at least one internship experience. Most of those bachelor's, master's and doctoral students that held an internship considered their internship experiences to be "very important". Of these master's candidates, 48% were employed within the geosciences at a company they had previously interned at the time.
An ambitious new study publishing October 15 in the open access journal PLOS Biology describes the full chain of events by which the ocean biogeochemical changes that are predicted to be triggered by manmade greenhouse gas emissions over the next 100 years may cascade through marine habitats and organisms, penetrating to the deep ocean and eventually influencing humans.
