Digging in the dirt for life's biochemical foundations

...s of the Green Revolution to increase agricultural yields around the world has relied on the use of synthetic nitrogen fertilizers. The price of fertilizers is increasing, however, as are concerns about nitrogen runoff from large agricultural operations. Nitrogen also is a component of acid rain, which rema...

Techniques available to detect soil that inhibits destructive soybean pest

.... Infestation gradually causes progressively lower yields and the worst cases result in yellow and stunted soybean plants. Plants with severe, visible damage can occur in patches in highly infested fields. There are no pesticides that will eradicate soybean cyst nematode, which also preys on other legumes ...

Stolen gene allows insect virus to enter cells

...chemical insecticides. Studying baculoviruses also yields insights into general viral behavior. The current study examined how baculoviruses took the evolutionary leap needed to become the nasty bugs they are today. In the study, reported in the July 1 issue of the Journal of Virology, BTI researchers Gary...

Color perception is not in the eye of the beholder: It's in the brain

...is means that looking at the retina from a cadaver yields almost no information on the arrangement of their cones, and there is certainly no ability to test for color perception. Likewise, the amino acids that make up two of the three different-colored cones are so similar that there are no stains that can ...

Purdue researchers find key to rice blast fungus

...deadly of the pathogens that attack rice, reducing yields by as much as 75 percent in infected areas. Learning how the fungus tricks rice's natural defenses against pathogens to penetrate the plant is an important part of controlling the disease, said Jin-Rong Xu, a Purdue molecular biologist. Xu, Xinhua Z...

California computer scientists double volume of data in NIH biotech repository

...eHigh-throughput sequencing of an individual's DNA yields a map of genetic variation which can give clues to the genetic underpinning of human disease. The current technologies collect genotypes, or information from the individual's two chromosomes. Yet many scientists believe that drilling down to the va...

U-M scientists say fused genes trigger the development of prostate cancer

Scientists must offer solutions for conserving tropical forests in a rapidly changing world

...ilitate degraded lands and to improve agricultural yields and living standards. According to William F. Laurance, Wright's colleague at STRI and frequent spokesman for conservation efforts in Africa and the Amazon, "the commitment of tropical biologists must go a step further to include effective communica...

Breath of the dragon: ERS-2 and Envisat reveal impact of economic growth on China's air quality

...ared regions. Mathematical inversion of these data yields the amounts and distribution of trace gases, ozone and related chemicals, clouds and dust particles throughout the atmosphere. With a 960-km swath and alternate limb and nadir observations, SCIAMACHY covers the entire world every six days at the equa...

Double trouble: Cells with duplicate genomes can trigger tumors

Abnormal cell division that yields cells with an extra set of chromosomes can initiate the development of tumors in mice, researchers at Dana-Farber Cancer Institute have shown, validating a controversial theory about cancer causation put forth by a scientific visionary nearly 100 yea...

University of Arizona plant scientists to unravel maize genome

..." Deciphering billions of letters of genetic code yields vast amounts of data, which have to be stored, accessed and interpreted. BIO5's capabilities in bioinformatics help scientists manage and analyze complex data. The software used to generate the genetic map was developed by Carol Soderlund, who hold...

How E. coli bacterium generates simplicity from complexity

...e parts has shown that all this genetic complexity yields surprisingly few physiological functions. This is possibly a general principal in many, if not all, species." Palsson and his colleagues at UCSD, postdoctoral fellows Christian L. Barrett and Christopher D. Herring, and Ph.D. candidate Jennifer L. R...

Biologists discover new pathway into plant cells

...multiple toxins that attack wheat plants, reducing yields and ruining wheat used as seed. In the United States, it's a particular problem in the Great Plains and Midwest. Ciuffetti has spent much of her career studying these "host-selective" toxins. "Until now, we didn't really know exactly how the protein...

New maps reveal true extent of human footprint on Earth

...ding a look at related factors such as global crop yields and fertilizer use. Distilling that information in...SAGE, is similarly mapping the location, range and yields of over 150 individual crops reared around the planet. The exercise is already beginning to cast li...

Sustainable farm practices improve Third World food production

Crop yields on farms in developing countries that used sustainable agriculture rose nearly 80 percent in four years, according to a study scheduled for publication in the Feb. 15 issue of the American Chemical Society journal Environmental Science & Techno...

Amazonian terra preta can transform poor soil into fertile

...ches us how to restore degraded soils, triple crop yields and support a wide array of crops in regions with agriculturally poor soils, but also can lead to technologies to sequester carbon in soil and prevent critical changes in world climate," said Johannes Lehmann, assistant professor of biogeochemistry i...

Researchers release new variety of asparagus

... at the moment, some of which may have even better yields than DePaoli." Currently, UCR is cultivating the DePaoli variety in a field near campus. The first test of the new variety, which involves evaluation of yield, spear quality, and other traits, was started in 1990. A full harvest of DePaoli was ob...

Honeybee decision-making ability rivals any department committee

... rather than consensus or compromise, consistently yields excellent collective decisions," said Seeley. When a hive gets too crowded, its queen and half the hive will swarm to a nearby tree and quietly wait while several hundred scouts go house hunting. To explore the decision-making process, the research...

Molecule by molecule, new assay shows real-time gene activity

...h DNA, an organism's long-term genetic repository, yields its crop of proteins. These random, or stochastic, bursts of protein expression are described in detail in a separate paper Xie and colleagues present this week in Nature. "Although central to life processes, the expression of many important genes t...
