UCSD scientists establish connection between life today and ancient changes in ocean chemistry
...their diverse expertise and found that trace-metal usage by present-day organisms probably derives from major changes in ocean chemistry occurring over geological time scales. Using protein structures for the first time in such a study, the research establishes one of the influences that geochemistry ha...... public health measures. Indiscriminate antibiotic usage results in real-time evolution of bacteria that resist treatment. Furthermore, the healthy carrier state provides a safe reservoir for these bacteria which allows them to evade short-term antibiotic treatment and vaccination, indicating that typhoid ...Factors affecting kernel yield in maize
...and barley) may lead to improvements in fertilizer usage and crop yield, thus mitigating the detrimental effects of the overuse of fertilizers on the environment. The roles of these two GS isoenzymes, products of the Gln1-3 and Gln1-4 genes, were investigated by examining the impact of knock-out mutation...New study to test statin-Parkinson's link
...se at that stage, statins will have been in common usage for more than a decade. Huang's new study will examine the statin link. A total of 16000 patients for whom 20 years of baseline fasting cholesterol measurements are available will be involved. Another large-scale trial investigating a cholesterol l......rease the crop yield by 39% while reducing the gas usage by 52%....Gene controlling circadian rhythms may be involved in onset of bipolar disorder
...on, there is a very high co-morbidity between drug usage and bipolar disorder, especially when patients are in the manic state." During the study, lithium was given to the mutant mice. Lithium, a mood-stabilizing medication, is most commonly used in humans to treat bipolar patients. Once treated with the...
