Washington, June 18 : Electronic devices that will be more efficient and consume less energy than those present today may be just round the corner-all thanks to a breakthrough discovery by researchers at the Department of Energy''s Oak Ridge National Laboratory (ORNL).

Washington, June 18 : A new study has determined that as rapidly rising temperatures in Africa threaten to scorch local varieties of maize and other food staples, the food security of many Africans will depend on sharing genetic resources with other nations in the continent.

Researchers at Stanford University's Program on Food Security and the Environment and the Rome-based Global Crop Diversity Trust conducted the study.

They warn that long-standing neglect of African crop collections held in genebanks means that breeders today don't have access to all of the varieties of Africa's primary cereal crops like maize, millet and sorghum, which are likely to be most helpful in allowing farmers to adapt to climate change.

Dr. Dirk Dittmer of UNC's School of Medicine writes in a study paper published in the journal PLoS Pathogens in April that the Kaposi sarcoma associated herpesvirus (KSHV) is not only present in every tumor cell, but that the cells also transcribe microRNAs (miRNA) from the virus.
