Key To Controlling Fruit Ripening Could Be In The Functions Of Chloroplasts
2012-11-01 14:51:47

University of Leicester Biologists may have unearthed the potential to manipulate the functions of chloroplasts, the parts of plant cells responsible for photosynthesis. Researchers in the University of Leicester's Department of Biology discovered that chloroplasts are affected by the ubiquitin proteasome system (UPS) — a process which causes the breakdown of unwanted proteins in cells, previously thought to only act on central parts of the cell. As a result, the researchers...

Oxygen's Rise And Fall In The Early Atmosphere And Ocean
2012-10-23 20:44:52

UC Riverside-led research team finds evidence for a dramatic rise in early oxygen about 2.3 billion years ago followed, more surprisingly, by an equally impressive fall Most researchers imagine the initial oxygenation of the ocean and atmosphere to have been something like a staircase, but with steps only going up. The first step, so the story goes, occurred around 2.4 billion years ago, and this, the so-called Great Oxidation Event, has obvious implications for the origins and evolution...

Recently, a mysterious seed fern, Lepidopteris baodensis sp. nov., dating to more than 251 million years ago (Ma), was discovered at the Baijiagou of Baode, Shanxi, China, from the Upper Permian Sunjiagou Formation. This discovery completely changed the understanding of the stratigraphic distribution of the genus Lepidopteris in China and promoted the taxonomic study of late Paleozoic plants. Since Schimper erected the genus Lepidopteris in 1869, its epidermal structure of subepidermal...

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. ...

Alpine Glaciers Important For Carbon Cycle 091812
2012-09-18 12:19:01

Alan McStravick for redOrbit.com - Your Universe Online On the surface, the term “carbon cycle” can seem cold and almost prosaic. It´s a term that many of us learned and came to understand in a third-grade science class, with the help of rudimentary illustrations of the sun shining down on the grass that the cow was about to devour for lunch and oversized arrows tracing the flow of energy for us. Like many things we learned in those early classes, it was diluted down to...

In a surprising finding, North Carolina State University researchers have shown that certain underground organisms thought to promote chemical interactions that make the soil a carbon sink actually play a more complex, dual role when atmospheric carbon levels rise. In a paper published in the Aug. 31 edition of Science, North Carolina State University researchers show that important and common soil microscopic organisms, arbuscular mycorrhizal fungi (AMF), play a role in sequestering...

Biomass Increase Found In West African Forests
2012-08-27 07:09:25

redOrbit Staff & Wire Reports - Your Universe Online Even in the midst of a four decade long drought, protected forests in West Africa have somehow experienced an increase in their carbon storage capacity in recent years, a team of researchers from Ghana and the UK have discovered. According to BBC News Environmental Reporter Mark Kinver, previous studies had suggested that a lack of precipitation in Ghana and the surrounding region resulted "in less carbon being stored as...
