The key to breeding disease-resistant honeybees could lie in a group of genes -- known for controlling hygienic behaviour -- that enable colonies to limit the spread of harmful mites and bacteria, according to genomics research conducted at York University. The researchers narrowed in on the 'clean' genes known to improve the colony's chance of survival. The finding was published today in the journal Genome Biology and Evolution.
A tiny insect, no bigger than the head of a pin, is threatening to topple the multibillion-dollar citrus industry in the US by infecting millions of acres of orchards with an incurable bacterium called citrus greening disease. The battle to save the citrus industry is pitting crop producers and a team of agriculture researchers -- including agricultural communications professor Taylor K. Ruth of the University of Illinois -- against a formidable brown bug, the Asian citrus psyllid, which spreads the disease.
Modern economies need courageous, entrepreneurial individuals to thrive yet the same qualities can bring greater risks according to a world-first study. QUT's Associate Professor Martin Obschonka joined forces with researchers from Germany's University of Mannheim and the University of Cambridge in the UK to study data on courage from more than 390,000 Americans. The project was a collaboration with Time Magazine which collected the data from an online Harry Potter-style sorting hat quiz publicized on its website.
Scientists aboard Schmidt Ocean Institute's research vessel Falkor surveyed deep-sea seamounts outside Isla del Coco UNESCO World Heritage site revealing coral communities with surprising diversity.
Theatre performances in zoos can be effective in increasing knowledge of important conservation messages, a study at the University of York has revealed.
Texas A&M graduate student aids in the discovery of flying squirrels fluorescing pink in UV light.
'Fungicides, often needed for crop protection, are routinely used during almond bloom, but in many cases growers were also adding insecticides to the mix. Our research shows that some combinations are deadly to the bees, and the simplest thing is to just take the insecticide out of the equation during almond bloom.'
Endangered and invasive species may be better managed in the future with new techniques outlined by a Texas A&M University scientist and others.
In efforts to curb our use of greenhouse gas-generating fossil fuels, plant-based biofuels are among the top contenders as alternative liquid energy sources for transportation. However, strategies to produce high yields of biomass for fuels are not a one-size-fits-all proposition, according to a study led by UC Santa Barbara professor of ecology David Tilman.
NIMS, the University of Tokyo and Hiroshima University jointly evaluated the economic efficiency of hydrogen production systems combining photovoltaic power generation and rechargeable batteries and estimated technology levels necessary for the systems to produce hydrogen at a globally competitive cost. The results obtained in this research may provide vital guidelines for pushing the intermittent renewable power generation systems as a main power source of the country.
