A novel bio-pesticide created using spider venom and a plant protein has been found to be safe for honeybees
New research led by Newcastle University UK has tested the insect-specific Hv1a/GNA fusion protein bio-pesticide--a combination of a natural toxin from the venom of an Australian funnel web spider
Publishing their findings today in the academic journal Proceedings of the Royal Society B the authors say the insect-specific compound has huge potential as an environmentally-benign'bee-safe'bio-pesticide and an alternative to the chemical neonicotinoid pesticides
Professor Angharad Gatehouse based in Newcastle University's School of Biology and one of the supervisors on the project explains:

The above story is provided based on materials by Marine Biological Laboratory. The original article was written by Diana Kenney.
The research was funded by the National Science Foundation's Division of Environmental Biology and the Yale Climate & Energy Institute.
The research which is funded by the National Science Foundation is published in BMC Plant Biology and includes along with Bais authors Carla Spence a doctoral student in the Department of Biological sciences Emily Alff who recently earned her master's degree in plant and soil sciences and Nicole Donofrio associate professor of plant and soil sciences all from UD;
and Sundaresan Venkatesan professor Cameron Johnson assistant scientist and graduate student Cassandra Ramos all from UC Davis. We truly are working to disarm a'cereal killer
For her work Spence the lead author recently received the Carson Best Paper Award for the best scientific paper published by a Ph d. student in biological sciences at UD.
In their study reported in BMC Plant Biology the researchers used gene sequencing techniques to identify 11 naturally occurring bacteria isolated from rice plants grown in the field in California.
So it's really cool to find a biological that can attenuate this thing. Bais who also has conducted multiple studies with beneficial microbes in the Bacillus family envisions a day
reducing emissions sequestering carbon through biological means on land and in the ocean storing carbon dioxide in a liquefied form in underground geological formations and wells increasing Earth's cloud cover and solar reflection.
Of the five options the group evaluated sequestering carbon through biological means --or converting atmospheric carbon into solid sources of carbon like plants--holds the most promise.
Improving soil management is another biological means of carbon sequestration that holds considerable promise because soils can trap plant materials that have converted already atmospheric carbon dioxide into a solid form as well as any carbon dioxide that the solids give off as they decompose.
The study also advocates a less familiar form of biological sequestration: the burial of biochar.
But not all biological sequestration would be so beneficial. The researchers evaluated the idea of adding iron to oceans

Norman Ellstrand a plant geneticist at the University of California Riverside is interested in many aspects regarding gene flow especially in applied plant biology
Selection mutation gene flow and genetic drift are the four mechanisms that lead to biological evolution or a change in allele frequencies in a population over time.
Interestingly Ellstrand points out that evolutionary biologists'view on the importance of gene flow has waxed
This review paper tells the story of gene flow's rise to respect among plant evolutionary biologists he concludes a fact that hasn't yet penetrated biology in general that is still mired in selection/adaptation-only thinking.
and scientists across the world will greatly aid in defining genotype/phenotype relationships as well as serve as an extensive resource improving our understanding of plant biology.

What we basically conclude is that neither of the existing theories about butterfly eyespots is correct said Jeffrey Oliver a postdoctoral scholar in the Department of Integrative Biology of the OSU College of Science.
And at all times they retained the biological capacity for positional awareness--the eyespots formed in the same place until a new mutation came along.
There would be a biological position in which they were supposed to form and that would be retained he said.

Sullivan and his colleagues used a new method to demonstrate that biological nitrogen fixation in tropical rain forests may be less than a quarter of previous estimates.
Nitrogen enters the environment either through a microbial process called biological nitrogen fixation or through human activity such as fertilization and fossil-fuel consumption.
He notes that human impacts on the nitrogen cycle typically are greatest where biological nitrogen fixation is low and human inputs of nitrogen are high-like in many parts of North america including Montana.
Past research has assumed that tropical rain forests have high levels of biological nitrogen fixation and that humans add relatively little nitrogen to tropical ecosystems.
