Fruit flies from different species can warn each other when parasitic wasps are near. But according to a new study led by Balint Z. Kacsoh of Geisel School of Medicine at Dartmouth, published July 19th in PLOS Genetics, they are more likely to get the message across if the fly species have previously cohabited and learned each other's dialects.
Nanoparticles with a wide range of applying, including medicine, damage cells of microalgae Heterosigma akashivo badly. This algae species is widely spread in the Russian Far East marine area. The acute toxic effect exhibited at concentrations of 100 mg/l of carbon nanotubes (CNTs) and silicon nanotubes (SiNTs) in the sea- or fresh water.
The research matched pollution data to monthly park visitation statistics at 33 heavily visited national parks and found that visitation responds most to ozone during months with poor air quality.
The research shows that a freshwater production strain of microalgae, Auxenochlorella protothecoides, is capable of directly degrading and utilizing non-food plant substrates, such as switchgrass, for improved cell growth and lipid productivity, useful for boosting the algae's potential value as a biofuel.
In a large international study involving almost 900,000 participants, researchers from the University of Copenhagen and COPSAC have found new risk genes for hay fever. It is the largest genetic study so far on this type of allergy, which affects millions of people around the world.
A switch from subsidizing fossil fuel to pricing CO2-emissions would not only help to meet global climate targets but also create additional domestic public revenues. These revenues could finance expenses towards sustainable development, improving health-care, education and infrastructure for energy, transportation or clean water. India could cover more than 90 percent of its needs to finance progress towards these sustainability goals. This could also be an attractive option for countries like Nigeria, Burundi and Senegal.
New research from scientists at Point Blue Conservation Science and The Nature Conservancy shows how financial incentive programs can create vital habitat for waterbirds, filling a critical need in drought years. Researchers used satellite images to evaluate two issues: 1) the impact of the 2013-2015 drought on waterbird habitat in the Central Valley; and, 2) the amount of habitat created by incentive programs.
A large-scale study published by researchers from Royal Holloway University of London has drawn together the findings of a decade of agrochemical research to confirm that pesticides used in crop protection have a significant negative impact on the learning and memory abilities of bees.
California has one of the world's most progressive cap-and-trade designed to reduce greenhouse gases. Yet in disadvantaged communities, emissions of those pollutants has actually gone up.
Epimeron, Inc., a world-class provider of gene discovery and biosynthetic pathway optimization, today announced the isolation and characterization of an enzyme from Ephedra sinica catalyzing an essential step in the formation of the important drugs ephedrine and pseudoephedrine. Deploying the gene encoding the newly discovered enzyme in microbes allows the production of ephedrine and pseudoephedrine by fermentation instead of using chemical processes. This breakthrough also enables the bioproduction of other pharmaceutically important related compounds.
