Latest species discovery: the littlest crayfish from down under
April 9, 2014 11:08 AM - Rob McCormack, The Australian Aquatic Biology Pty.
Hidden in one of Australia's most developed and fastest growing areas lives one of the world's smallest freshwater crayfish species. Robert B. McCormack the Team Leader for the Australian Crayfish Project described the new species belonging to the genus Gramastacus, after 8 years of research in the swamps and creeks of coastal New South Wales, Australia. The study was published in the open access journal ZooKeys.
At more than 23,000 feet, why don't bar-headed geese get hypoxic?
April 9, 2014 10:04 AM - ENN Staff
The bar-headed goose migratory path takes it over the Himalayan Mountains each year between China and Mongolia to their Indian breeding grounds. This flight path puts them at 23,917 feet above sea level. University of Exeter led study followed these birds to gain insight into their ability to survive these extreme altitudes in hopes that their findings might have future implications for low oxygen medical conditions in humans.
High Tech Trees!
April 8, 2014 01:20 PM - ENN Staff
Scientists at Oregon State University have found a way to convert tree cellulose into high-tech energy storage devices. Because cellulose is a key component of trees and the most abundant organic polymer on earth this discovery will have a profound impact in industry. Scientists were able to heat the tree cellulose in a furnace in the presence of ammonia to create the building block for supercapacitors for use in industrial electronic applications. Supercapacitors are extraordinarily, high-power energy devices for which production has been held back by cost and difficulty in producing high-quality carbon electrodes.
Shifting bird and reptile distributions
April 8, 2014 12:23 PM - Robin Blackstone, ENN
With climate change come several dramatic shifts in species distribution within the United States. The U.S. Geological Survey in concert with the University of New Mexico and Northern Arizona University have recently projected distribution losses for nearly half of the 5 examined reptile species including the locally famed chuckwalla. Breeding bird ranges, however exhibited broader expansions and contractions within their breeding habitats.
Desert absorption helps curtail CO2 levels
April 7, 2014 09:55 AM - Eric Sorensen, Washington State University News
Researchers led by a Washington State University biologist have found that arid areas, among the biggest ecosystems on the planet, take up an unexpectedly large amount of carbon as levels of carbon dioxide increase in the atmosphere. The findings give scientists a better handle on the earth's carbon budget — how much carbon remains in the atmosphere as CO2, contributing to global warming, and how much gets stored in the land or ocean in other carbon-containing forms.
Unearthing of large tusk in Arabian Desert suggests once greener pastures
April 4, 2014 09:49 AM - ENN Staff
Working in conjunction with the Saudi Commission for Tourism and Antiquities, researchers from the University of Oxford have discovered two pieces of a tusk that when combined measure six feet in length. The researchers believe it is from a Palaeoloxodon or a "straight tusked elephant". An elephant's carpal bone was recovered in a separate study done by a Swiss team in the Nefud Desert just five meters away. The sand layer dates back to approximately 325,000 years and the elephant is believed to be of the same age.
Crib mattresses expose infants to harmful emissions
April 2, 2014 03:30 PM - ENN Staff
University of Texas at Austin's Cockrell School of Engineering has found that crib mattresses expose sleeping infants to high levels of chemical emissions. Specifically, the team analyzed the foam padding from crib mattresses and found that the mattresses release significant amounts of volatile organic compounds (VOCs) which are potentially harmful chemicals found in many household items including cleaners and scented sprays.
American's energy usage jumps in 2013
April 2, 2014 01:08 PM - ENN Staff
Despite many individual efforts to decrease energy usage for 2013 increased by 2.3 Quadrillion thermal units over the previous year. These statistics have been monitored and presented by the Lawrence Livermore National Laboratory (LLNL) in the most recent energy flow charts measuring renewable, fossil and even nuclear energy.
Cost of agriculture related emissions outweigh benefits
March 29, 2014 08:03 AM - Editor, ENN
Revenues associated with ammonia pollution generated by agriculture equate to higher than expected health care costs according to Harvard researchers Fabien Paulot and Daniel Jacob. The NASA funded study used computer models that identified the harmful ammonia emissions created by the interaction of agriculturally generated ammonia in the atmosphere.
A sooner Spring and a later Autumn suggests the new normal
March 28, 2014 10:36 AM - University of Southampton newsroom
A study by the University of Southampton suggests that on average the end of Autumn is taking place later in the year and Spring is starting slightly earlier. A team of researchers examined satellite imagery covering the northern hemisphere over a 25-year period (1982 - 2006), and looked for any seasonal changes in vegetation by making a measure of its 'greenness'. They examined in detail, at daily intervals, the growth cycle of the vegetation — identifying physical changes such as leaf cover, color and growth.
