Green Solution In Fight Against Greenhouse Gases
2012-09-24 04:53:29

redOrbit Staff & Wire Reports - Your Universe Online Researchers are working on safer, more cost-effective carbon capture technology that could help overcome some of the obstacles currently facing projects designed to help reduce greenhouse gases and combat global climate changes, according to several recently published news reports. On Sunday, Reuters reporter Chris Wickham detailed a new material constructed from aluminum nitrate salt, inexpensive organic materials, and water...

Marine Microbes Engage In Unusual Symbiosis
2012-09-22 09:56:42

April Flowers for redOrbit.com - Your Universe Online A study published in this week's issue of Science shows how tiny, single-celled algae and a highly specialized bacteria have formed a partnership that helps keep the ocean fertilized.  This symbiotic pair takes nitrogen from the atmosphere and "fixes" it into a form that other organisms can use. The results of the study emerged from the investigation of a mysterious nitrogen-fixing microbe that has a very small genome. ...

Crops Possibly Protected From Stressors Due To New Discovery

Salk findings of a key genetic mechanism in plant hormone signaling may help save crops from stress and help address human hunger Scientists at the Salk Institute for Biological Studies have discovered a key genetic switch by which plants control their response to ethylene gas, a natural plant hormone best known for its ability to ripen fruit, but which, under stress conditions, can cause wilted leaves, premature aging and spoilage from over-ripening. The findings, published August 30 in...

Why Peppers Do Not Mature After Picking

Climacteric and non-climacteric fruits react differently to the plant hormone ethylene Tomato breeders scored a coup several years ago when they identified tomatoes with a genetic defect that made the fruits mature very slowly, even under the influence of the phytohormone ethylene. Traders and growers were delighted as it gave them more time to transport the crop, initially still green, from where it was harvested to where it would be sold. At the stores, the tomatoes could then be treated...

UCLA life scientists, working with colleagues in China, have discovered a new method to quickly assess plants' drought tolerance. The method works for many diverse species growing around the world. The research, published in the journal Methods in Ecology and Evolution, may revolutionize the ability to survey plant species for their ability to withstand drought, said senior author Lawren Sack, a UCLA professor of ecology and evolutionary biology. "This method can be applied rapidly and...

Light is not only the source of a plant's energy, but also an environmental signal that instructs the growth behavior of plants. As a result, a plant's sensitivity to light is of great interest to scientists and their research on this issue could help improve crop yields down the road. Similarly understanding a plant's temperature sensitivity could also help improve agriculture and feed more people. Two new papers from Carnegie's Zhiyong Wang laboratory identify key aspects of the hormonal...

University of Adelaide researchers have discovered that recent climate change is causing leaves of some Australian plants to narrow in size. The study, which is the first of its kind in the world, highlights that plant species are already responding to changes in climate. The results are published online today in the Royal Society journal Biology Letters. Researchers analysed leaves from herbarium specimens of Narrow-leaf Hopbush (Dodonaea viscosa subsp. angustissima) dating from the...

Boston College chemists use nanowires to power photosynthesis Harnessing the power of the sun has inspired scientists and engineers to look for ways to turn sunlight into clean energy to heat houses, fuel factories and power devices. While a majority of this research focuses on energy production, some researchers are looking at the potential uses of these novel solar technologies in other areas. Boston College Assistant Professor of Chemistry Dunwei Wang's work with silicon nanowires...

Ancient Human Predecessors Were Tree-Climbing Bark Eaters

[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online An international team of scientists has revealed that the ancestors of modern humans had an unusual diet -- one which may have contributed to their ultimate downfall, according to various reports published Wednesday. According to Thomas H. Maugh II of the Los Angeles Times, researchers led by the Max Planck Institute of Evolutionary Anthropology in Leipzig, Germany have discovered that Australopithecus...

UCLA life scientists have discovered new laws that determine the construction of leaf vein systems as leaves grow and evolve. These easy-to-apply mathematical rules can now be used to better predict the climates of the past using the fossil record. The research, published May 15 in the journal Nature Communications, has a range of fundamental implications for global ecology and allows researchers to estimate original leaf sizes from just a fragment of a leaf. This will improve scientists'...

Bittercress (Barbarea vulgaris), also commonly known as Herb Barbara, Rocketcress, Yellow Rocketcress, Winter Rocket, and Wound Rocket, is a European biennial herb. This plant displays a rosette of shiny, dark green leaves at the base and additional pinnately divided leaves on the stem. In the spring, yellow flowers originate in tightly packed terminal groups just above the foliage. Bittercress grows wildly as a weed in many parts of North America. The flowers can be in bloom May...

The Par Rubber Tree (Hevea brasiliensis), is a tree belonging to the family Euphorbiaceae. It is the most economically important member of the genus Hevea. It is of major economic importance because its sap-like extract (latex) can be collected and is the primary source of natural rubber. The Pará rubber tree initially grew only in the Amazon Rainforest. Now most rubber tree plantations are in southeast Asia and tropical Africa. Attempts to cultivate the tree in other areas in South...
