AUSTIN, Texas — An international team of scientists that includes two University of Texas at Austin researchers has found that Ecuador’s Yasuní National Park, which sits on top of massive reserves of oil, is in the single most biodiverse region in the Western Hemisphere.
The announcement is part of a final push for the Yasuní-ITT Initiative at the United Nations General Assembly. The initiative proposes that Ecuador receive compensation for half of the revenues the nation would lose by protecting the estimated 846 million barrels of oil that lie beneath the forest. (more…)
*Plants and animals that live on Britain’s coasts could benefit from changes to the way coastal structures such as seawalls, breakwaters, rock armour and jetties are designed and built.*
*Research by the Universities of Exeter and Plymouth and Treweek Environmental Consultants, supported by the Environment Agency, has led to the development of recommendations for the design and construction of coastal defence structures.*
The team has produced guidance on how the ‘ecological enhancement’ of hard coastal structures can be embedded in the design and planning process, from conception through to construction.
Past research has found that hard structures are poor ecological substitutes for natural rocky shores, often supporting only a few dominant, opportunistic species such as green algae. The research team assessed the suitability of different materials, surface roughness, positioning and height for coastal habitats. They examined structures across the South West coast, including Ilfracombe in Devon and Newlyn in Cornwall, as well as looking further afield to work from Sydney Harbour in Australia and Seattle Harbour in the USA. They focused on organisms such as barnacles and limpets as these dominate many rocky shore environments and rapidly colonise hard surfaces placed in the sea, including harbour walls. Once these organisms have established themselves, other plants and animals typically follow, to the benefit of species such as salmon. (more…)
AUSTIN, Texas — Scientists from the U.S., U.K. and Australia have used ice-penetrating radar to create the first high-resolution topographic map of one of the last uncharted regions of Earth, the Aurora Subglacial Basin, an immense ice-buried lowland in East Antarctica larger than Texas.
The map reveals some of the largest fjords or ice cut channels on Earth, providing important insights into the history of ice in Antarctica. The data will also help computer modelers improve their simulations of the past and future Antarctic ice sheet and its potential impact on global sea level. (more…)
EAST LANSING, Mich. — For women, shopping is more than just buying stuff. For some it can be therapeutic, for others a time to socialize, or for some a challenge to find the right product at the right price.
Michigan State University’s Patricia Huddleston is co-author of a new book, “Consumer Behavior: Women and Shopping,” which looks at the reasons why women go shopping, as well as provides a history of how shopping has evolved over the years. (more…)
PASADENA, Calif. — A five-year survey of 200,000 galaxies, stretching back seven billion years in cosmic time, has led to one of the best independent confirmations that dark energy is driving our universe apart at accelerating speeds. The survey used data from NASA’s space-based Galaxy Evolution Explorer and the Anglo-Australian Telescope on Siding Spring Mountain in Australia.
The findings offer new support for the favored theory of how dark energy works — as a constant force, uniformly affecting the universe and propelling its runaway expansion. They contradict an alternate theory, where gravity, not dark energy, is the force pushing space apart. According to this alternate theory, with which the new survey results are not consistent, Albert Einstein’s concept of gravity is wrong, and gravity becomes repulsive instead of attractive when acting at great distances.

*Study shows daily malleability on a long-term question*
Social scientists are struggling with a perplexing earth-science question: as the power of evidence showing manmade global warming is rising, why do opinion polls suggest public belief in the findings is wavering? Part of the answer may be that some people are too easily swayed by the easiest, most irrational piece of evidence at hand: their own estimation of the day’s temperature.
In three separate studies, researchers affiliated with Columbia University’s Center for Research on Environmental Decisions (CRED) surveyed about 1,200 people in the United States and Australia, and found that those who thought the current day was warmer than usual were more likely to believe in and feel concern about global warming than those who thought the day was unusually cold. A new paper describing the studies appears in the current issue of the journal Psychological Science. (more…)

GAINESVILLE, Fla. — Red imported fire ant invasions around the globe in recent years can now be traced to the southern U.S., where the nuisance insect gained a foothold in the 1930s, new University of Floridaresearch has found.
Native to South America, the ant had been contained there and in the southeastern U.S. before turning up in faraway places in the last 20 years — including California, China, Taiwan, Australia and New Zealand. (more…)
