They Call It 'Guppy Love'
2011-11-25 04:34:35

UCLA biologists solve an evolution mystery Guppies in the wild have evolved over at least half-a-million years – long enough for the males' coloration to have changed dramatically. Yet a characteristic orange patch on male guppies has remained remarkably stable, though it could have become redder or more yellow. Why has it stayed the same hue of orange over such a long period of time? Because that's the color female guppies prefer. "Sometimes populations have to evolve just to...

New grass family tree reveals C4 photosynthesis is an evolutionary 1-way street If you eat bread stuffing or grain-fed turkey this Thanksgiving, give thanks to the grasses – a family of plants that includes wheat, oats, corn and rice. Some grasses, such as corn and sugar cane, have evolved a unique way of harvesting energy from the sun that's more efficient in hot, arid conditions. A new grass family tree reveals how this mode of photosynthesis came to be. The results may one day...

Research at Iowa State University has led to discovery of a genetic method that can increase biomass in algae by 50 to 80 percent. The breakthrough comes from expressing certain genes in algae that increase the amount of photosynthesis in the plant, which leads to more biomass. Expressing genes means that the gene's function is turned on. "The key to this (increase in biomass) is combination of two genes that increases the photosynthetic carbon conversion into organic matter by 50...

Atmospheric carbon dioxide (CO2) is one of the most important greenhouse gases and the increase of its abundance in the atmosphere by fossil fuel burning is the main cause of future global warming. In past times, during the transition between an ice age and a warm period, atmospheric CO2 concentrations changed by some 100 parts per million (ppm) — from an ice age value of 180 ppm to about 280 ppm during warm periods. Scientists can reconstruct these changes in the atmospheric carbon...

U.S. scientists have developed a new, integrated, ten-year science plan to better understand the details of Earth's carbon cycle and people's role in it. Understanding the carbon cycle is central for mitigating climate change and developing a sustainable future. The plan builds on the first such plan, published in 1999, but identifies new research areas such as the role of humans as agents and managers of carbon cycling and climate change, the direct impact of greenhouse gases on ecosystems...

The carbon footprint of humans will be reduced by four awards for plant and microbial research issued under a new joint U.S./Japanese program Four joint United States and Japanese research teams have been awarded funding totaling about $12 million (about Yen 960 million) to develop new environmentally-friendly techniques to increase the production of renewable biofuel and reduce pesticide use. These environmentally-friendly techniques will be based on studies of metabolites--chemical...

Max Planck scientists discover photosynthesis helper protein in red algae Photosynthesis is one of the most important biological processes. However, it is less efficient in plants than it could be. Red algae, in contrast, use a slightly different mechanism and are thus more productive. Scientists from the Max Planck Institute of Biochemistry (MPIB) in Martinsried near Munich, Germany, have now identified a so far unknown helper protein for photosynthesis in red algae. “We could...

The discovery of a new gene is helping researchers at Michigan State University envision more-efficient molecular factories of the future. A team of researchers, led by Katherine Osteryoung, MSU plant biologist, announced the discovery of Clumped Chloroplasts — a new class of proteins — in the current issue of the Proceedings of the National Academy of Sciences. CLMP1 plays a key role in helping chloroplasts, which carry out the life-sustaining process of photosynthesis,...

“Albedo Effect” In Forests Can Cause Added Warming, Bonus Cooling
2011-10-20 06:10:28

Wildfire, insect outbreaks and hurricanes destroy huge amounts of forest every year and increase the amount of carbon dioxide entering the atmosphere, but scientists are now learning more about another force that can significantly affect their climate impact. Researchers conclude in a new study that the albedo effect, which controls the amount of energy reflected back into space, is important in the climatic significance of several types of major forest disturbances. In some cases...

RUB biologists publish new model for protein transport in plant cells How the light-harvesting complexes required for photosynthesis get to their site of action in the plant cell is reported by RUB biologists in the Journal of Biological Chemistry. The team led by Prof. Dr. Danja Schünemann (RUB working group on the molecular biology of plant organelles) has demonstrated for the first time that a membrane protein interacts with a single soluble protein to anchor the subunits...


Word of the Day
glogg
  • Scandinavian punch made of claret and aquavit with spices and raisins and orange peel and sugar.
This word comes from the Swedish 'glogg,' which is an alteration of 'glodgat,' mulled (wine).
