We study the evolution and function of mammalian and bacterial genomes using computers as our microscope.
Heat stress is a major inhibitor of production in livestock operations, causing severe economic loss. Environmental and management stressors erode efficiency and cost livestock production enterprises billions of dollars annually in lost potential profitability. For example, in the absence of heat abatement measures, total losses across all animal classes averaged $2.4 billion annually (St-Pierre et al., 2003). The objective of this study was to explore an alternative way to cool cows in times of heat stress.
This project develops a new methodology to ascertain the shadow value of net imports and exports. The methodology is readily implementable and contributes to an understanding of both the success and failure of dispute-settlement mechanisms currently adopted in multilateral trade agreements such as the World Trade Organization.
Recent assessment reports of the Intergovernmental Panel on Climate Change (IPCC) have stated that “warming of the climate system is unequivocal” and have documented widespread evidence of global warming and other major climatic changes, as well as their impacts. These impacts in rural areas -– on agriculture, farmers, rural households and rural communities -– can be expected to be increasingly substantial. This project reports the results of research to identify and prioritize stakeholder-driven, locally relevant response options to climate change affecting agriculture in the Middle East.
Western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) are tiny insects, but are considered one of the most-economically important pests of agricultural crops worldwide. They cause substantial losses not only through direct feeding, but also by transmitting viruses. Due to their small size and secluded behavior, chemical control is the most effective way to achieve control. However, intensive insecticide use combined with a short generation time, high fecundity and haplodiploid reproduction system promote the rapid development of resistance.
Algorithms have become critically important in structuring how we communicate, how we understand, how we buy, how we predict, and how we participate in public life. Evidence of this is everywhere: the democratic process, political campaigns, and the ongoing relations between citizens and government; the workings of the financial market and consumer sphere; our encounters with popular entertainment and public knowledge; our interactions with our social networks; education, academic research, and the production of knowledge.
The Cornell Small Grains Breeding and Genetics Project has released a new soft white winter wheat variety called Medina with exceptionally high grain yield, grain quality and disease resistance. This variety is moderately resistant to fusarium head blight and is more sprout resistant than older varieties, thus increasing the efficiency of production for the farmer and thereby resulting in higher profits.
Conversion of lands in the Northeast to perennial grass bioenergy crops is not merely a future possibility; it is already underway. These crops provide net energy returns that are greater than conventional row crops, as well as such ecosystem benefits as increased organic matter levels in soil, reduced erosion potential, and low fertilizer and pesticide requirements.
U.S. ethanol policies have contributed to changes in the levels and the volatilities of revenues and costs facing ethanol firms. The implications of these policies for optimal investment behavior are investigated through an extension of the real options framework that allows for the consideration of volatility in both revenue and cost components, as well as their correlation. The effects of policy on plant revenues dominate the effects of those policies on production costs.
Dietary vitamin E does not reflect what is deposited and retained by the body. Although this has been known for many years, there is currently no consensus on why this occurs. I am exploring a biological basis for this apparent discrimination. By reviewing the literature of
vitamin E metabolism, I propose to provide a rational explanation for this phenomenon. Our work in various cells and organisms provides insight into this question. My colleagues and I are proposing to assemble a literature review outlining an argument against supplementation
