Pesticides choke pathway for nature to produce nitrogen for crops

...0 that had found significant declines in both crop yield per unit of synthetic nitrogen fertilizer added and also a significant decline in overall symbiotic nitrogen fixation. The most common explanation for the observations is an overuse of agrichemicals applied to legume crops. That practice sets up "...

Mutating the entire genome

... cells, which means those cells are less likely to yield mice with the desired stretch of DNA disabled, Capecchi says. To quickly, cheaply mutate genes or none-gene DNA, Wu and Capecchi used short pieces of DNA known as loxP. Pieces of loxP act like signposts saying, “Cut the DNA between these two sign...

... tiny computer chip that do chemical reactions and yield molecules that bind to receptor sites. Kevin Moeller, Ph.D., Washington University professor of chemistry in Arts & Sciences, is doing this so that the electrodes on the chip can be used to monitor the biological behavior of up to 12,000 molecule...

Genetic roots of bipolar disorder revealed by first genome-wide study of illness

...few of these genes or the proteins they make could yield substantial benefits for patients. Lithium is still the primary treatment for bipolar disorder, but DGKH is a promising target for new treatments that might be more effective and better tolerated," McMahon said. The finding was enabled by recent ...

Beyond the DNA: Chemical signatures reveal genetic switches in the genome

... applicable and its unbiased approach is likely to yield new information on gene expression and how it is altered in disease. "The beauty of this approach is that it utilizes a chemical signature present on histones but not DNA. Existing methods to predict enhancers rely on the DNA sequence alone, but thes...
