Scientists on the Norwich Research Park, working with colleagues in China, have developed new techniques that will aid the application of genomics to breeding the improved varieties of crop needed to ensure food security in the future. By dissecting the complicated genome of oilseed rape they have been able to produce maps of the genome that are needed for predictive breeding.

New York, NY—July 31, 2011—Samuel K. Sia, assistant professor of biomedical engineering at Columbia Engineering, has developed an innovative strategy for an integrated microfluidic-based diagnostic device—in effect, a lab-on-a-chip—that can perform complex laboratory assays, and do so with such simplicity that these tests can be carried out in the most remote regions of the world.
Researchers at the RIKEN Center for Genomic Medicine (CGM), together with colleagues at Kyoto University, Tsukuba University, Harvard University, and other medical institutions have identified three new loci associated with susceptibility to adult asthma in the Japanese population. The findings appear in Nature Genetics and derive from a genome-wide study of 4836 Japanese individuals.
How do cells know where to position themselves and where to accumulate in order to carry out their functions correctly within each organ? Researchers with the Colorectal Cancer Lab at IRB Barcelona have revealed the molecular mechanisms responsible for organizing the intestinal epithelium into distinct comportments, defined by frontiers or territories.
Seventy per cent of eight-month-old babies have a salt (sodium chloride) intake higher than the recommended UK maximum level, due to being fed salty and processed foods like yeast extract, gravy, baked beans and tinned spaghetti.
PHILADELPHIA — Even in trace quantities, the radioactive gas radon is very dangerous; it is second only to cigarette smoking as a cause of lung cancer deaths in the United States. The expense and precautions necessary to study it safely have limited research into its properties. Now, University of Pennsylvania chemists have for the first time measured how well radon binds to a molecule, paving the way for future research on it and other noble gasses.
New Rochelle, NY, July 29, 2011–Intravenous delivery of cold fluids to reduce body temperature quickly after a heart attack and improve neurologic outcomes may not be as effective in children as it is in adults, according to a study reported in Therapeutic Hypothermia and Temperature Management, a peer-reviewed journal published by Mary Ann Liebert, Inc. The article is available free online at www.liebertpub.com/ther
Los Angeles, CA (July 29th, 2011) – The city of Liverpool made a bold move in investing in exhibiting at the 2010 World Expo in its twin city of Shanghai, China. According to research in the journal Local Economy published by SAGE, the city is beginning to reap the benefits both of inward investment, and of a higher profile in, and strengthened relationships with China.
The first screening by U.S. Department of Agriculture (USDA) scientists of the American ancestors of soybeans for tolerance to ozone and other stresses had an eye-opening result: The world superstars of stress resistance hailed from a little village in far northern Sweden, called Fiskeby.
NEW YORK (July 28, 2011) -- The ability to tag proteins with a green fluorescent light to watch how they behave inside cells so revolutionized the understanding of protein biology that it earned the scientific teams who developed the technique Nobel Prizes in 2008. Now, researchers at Weill Cornell Medical College have developed a similar fluorescent tool that can track the mysterious workings of the various forms of cellular RNA.
Feeding mannan oligosaccharides (MOS) can fine-tune the immune system of pigs, suggests a new University of Illinois study.
"When it comes to keeping pigs healthy, there are some potentially powerful tools we can use in the diet besides antibiotics," said James Pettigrew, U of I professor of animal science. "We have a tendency to think that we can administer health through a needle, by giving pigs antibiotics, and even through systems like all-in/all-out pig flow. These are important, but there are also many health benefits we can realize through the diet."
California's native grasses, already under pressure from invasive exotic grasses, are likely to be pushed aside even more as the climate warms, according to a new analysis from the University of California, Berkeley.
In the study, which has been accepted for publication in the journal Global Change Biology and is now available online, UC Berkeley biologists catalogued the ranges of all 258 native grasses and 177 exotic grasses in the state and estimated how climate change – in particular, increased temperature and decreased rainfall – would change them.
PASADENA, Calif.—If one is good, two can sometimes be better. Researchers at the California Institute of Technology (Caltech) have certainly found this to be the case when it comes to a small HIV-fighting protein.
The protein, called cyanovirin-N (CV-N), is produced by a type of blue-green algae and has gained attention for its ability to ward off several diseases caused by viruses, including HIV and influenza. Now Caltech researchers have found that a relatively simple engineering technique can boost the protein's battling prowess.
The research efforts of University of Guam scientist Thomas Marler have put Guam's endangered native cycad, Cycas micronesica (fadang is the Chamorro name) on the cover of the June 2011 International Journal of Plant Sciences (IJPS). Published by the University of Chicago Press, IJPS is an important source for researchers looking for new and dynamic articles in the field of botany.
Some compounds found in grapes help to protect skin cells from the sun's ultraviolet radiation, according to a study by researchers from the University of Barcelona and the CSIC (Spanish National Research Council). The study supports the use of grapes or grape derivatives in sun protection products.
