Plants grow bigger and more vigorously through changes in their internal clocks
Hybrid plants, like corn, grow bigger and better than their parents because many of their genes for photosynthesis and starch metabolism are more active during the day, report researchers from The University of Texas at Austin in a new study published in the journal Nature. view more (2008-11-24)
First national study to quantify GM hybrids across the UK
Pioneering research that quantifies cross-fertilisation between crops and their wild relatives will help to assess the risk of hybridisation associated with growing GM crops in the UK, according to a report published today in the journal Science. view more (2003-10-09)
Carnegie Mellon researchers urge development of low carbon electricity
Carnegie Mellon University's Constantine Samaras and Kyle Meisterling report that plug-in hybrid electric vehicles could help reduce greenhouse gas emissions that fuel global warming, but the benefits are highly dependent on how the electricity system changes in the coming decades. view more (2008-04-28)
When you've doubled your genes, what's 1 chromosome more or less?
An individual with Down syndrome and a male calico cat have one thing in common-each has an extra chromosome. For animals, most instances of an extra chromosome result in birth defects or even death, but plants are another matter entirely. view more (2009-09-15)
AgriLife Research breeder develops drought-tolerant corn
At the end of the day, drought tolerance in corn has to equate to good yields and good quality, not just good looks, said a Texas AgriLife Research scientist. view more (2008-08-26)
Hybrid bluegrasses analyzed for use in transition zone
The transition zone can be one of the most challenging places to maintain high-quality turfgrass; changeable growing conditions in these regions often prove too hot for some grasses and too cold for others. Finding turfgrass that thrives in these challenging environments can be perplexing for turf management professionals and homeowners alike. view more (2009-11-05)
UT researcher sheds new light on hybrid animals
What began more than 50 years ago as a way to improve fishing bait in California has led a University of Tennessee researcher to a significant finding about how animal species interact and that raises important questions about conservation. view more (2007-09-18)
Thriving Hybrid Salamanders Contradict Common Wisdom
A new UC Davis study not only has important findings for the future of California tiger salamanders, but also contradicts prevailing scientific thought about what happens when animal species interbreed. view more (2007-09-27)
Hybrid vehicle rebates produce scant environmental benefits, high cost
Despite major costs to taxpayers in the U.S. and Canada, government programs that offer rebates to hybrid vehicle buyers are failing to produce environmental benefits, a new UBC study says. view more (2009-08-04)
Historical Increase in Corn Yield -- It's in the Roots
One of the most significant developments in agricultural growth in modern times has been the continuous and substantial increase in corn yield over the past 80 years in the U.S. Corn Belt. view more (2009-03-17)
New public-private hybrid rice group aims to raise rice yields in the tropics
A new international research initiative, linking the private and public sectors for the first time and launched on November 9 at the 2007 Asian Seed Congress, aims to boost the research and development of hybrid rice for the tropics. view more (2007-11-12)
Do higher corn prices mean less adherence to ecological principles?
Expectations of higher corn prices are leading some farmers to neglect or ignore integrated pest management strategies, and their behavior could undermine the very technologies that sustain them, University of Illinois researchers report today at the American Chemical Society meeting in Boston. view more (2007-08-22)
Knockout broccoli fights cancer
EATING your greens could be even better for you than anyone thought. Macerated raw broccoli turns out to contain small amounts of a potent chemical that inhibits the oxidising enzymes that damage DNA and potentially cause cancer. When you chew broccoli, its cells rupture, releasing an enzyme that produces a class of chemicals called... view more... (2003-04-05)
Inconspicuous leaf beetles reveal environment's role in formation of new species
Unnoticed by the nearby residents of St. Johnsbury, Vermont, tiny leaf beetles that flit among the maple and willow trees in the area have just provided some of the clearest evidence yet that environmental factors play a major role in the formation of new species. view more (2009-11-02)
New evidence supports century-old theory of cancer spread
A Yale School of Medicine study in the December issue of Lancet Oncology challenges mainstream oncology researchers to consider tumor cell hybridization with white blood cells as a major reason that cancer metastasizes or spreads to other parts of the body. view more (2005-12-13)
Earlier plantings underlie yield gains in northern Corn Belt
U.S. farmers plant corn much earlier today than ever before and it seems to be paying off, at least in the north. Earlier plantings could account for up to half of the yield gains seen in some parts of the northern Corn Belt since the late 1970s, a new study has found. view more (2008-02-28)
Invasive species alter habitat to their benefit
When scientists study habitats that alien species have invaded, they usually find predictable patterns. The diversity of native species declines, and changes occur in natural processes such as nutrient cycling, wildfire frequency and the movement of water through the system. view more (2006-08-10)
Genome duplication responsible for more plant species than previously thought
Extra genomes appear, on average, to offer no benefit or disadvantage to plants, but still play a key role in the origin of new species, say scientists from Indiana University Bloomington and three other institutions in this week's Proceedings of the National Academy of Sciences. view more (2009-08-13)
X-Effect: Female Chromosome Confirmed a Prime Driver of Speciation
Researchers at the University of Rochester believe they have just confirmed a controversial theory of evolution. The X chromosome is a strikingly powerful force in the origin of new species. view more (2007-10-18)
UC Riverside researchers release new variety of asparagus
UC Riverside researchers have released a new variety of asparagus that offers a higher yield than previous varieties of the vegetable and boasts an excellent spear quality, marked by a high percentage of marketable spears. view more (2006-02-15)
