Adding to evidence that pesticide use may be abetting the decline of bumblebee, a new study reveals that daily consumption of even small doses of neonicotinoids reduces the survival of queen and male bees, which are critical to the viability of wild populations. The study also found that exposure to neonicotinoids alters the expression of many bee genes, suggesting that the chemicals may be having a greater impact on wild bee populations than previously thought.
Can humans drive economic growth, meet rising demand for food, energy and water, and make significant environmental progress? The short answer is 'yes,' but it comes with several big 'ifs.' New research shows that we can put the world on a path to sustainability if we make significant changes within the next 10 years.
The environmental costs of smartphones are often exacerbated by the relatively short lifespans of these globally ubiquitous devices. When it comes to extending the lifespan of these products, brand name might be more important than repairability, a Yale-led study finds.
The name itself, cryptocurrency, does not inspire trust. Clusters of bits, considered by many as money of a doubtful nature. Advanced statistical analysis for the Bitcoin market carried out at the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow, however, has not shown any significant differences between its basic statistical parameters and their equivalents for respected financial markets. All indications are that Bitcoin is a better currency than it might seem at first glance.
An increasing number of people no longer identify as either a 'man' or 'woman' but instead choose other gender options. New research by QUT, based on the results of the Australian Sex Survey, has looked at the biological and sociological factors associated with non-binary gender identity recognition -- and how it differs between the sexes.
Species-rich subtropical forests can take up twice as much carbon as monocultures. This has been reported by an international research team in Science. The study was carried out as part of a unique field experiment with forests grown specifically for this purpose in China. Data from plots with a total of over 150,000 trees were analyzed. The results speak in favor of using many different tree species during reforestation. Thus, both species conservation and climate protection can be promoted.
Cash-strapped environmental regulators have a powerful and cheap new weapon. Machine learning methods could more than double the number of violations detected, according to Stanford researchers.
Cattle ranching and conservation may seem an unusual pair in the American West, but new research reveals a clear link between the economic health of ranches and the ability to maintain habitat for an iconic wild bird that for years has been at the center of public land policy debate: the greater sage grouse.
When invasive species enter the picture, things are rarely black and white. A new paper has revealed that some plant invaders could help fight climate change by making it easier for ecosystems to store 'blue carbon' -- the carbon stored in coastal environments like salt marshes, mangroves and seagrasses. But other invaders, most notably animals, can do the exact opposite.
Alaska has a near-pristine marine ecosystem--it has fewer invasive species in its waters than almost any other state in the U.S. But that could be changing. With help from local volunteers, biologists at the Smithsonian Environmental Research Center (SERC) and Temple University have reported a new invasive species in the Ketchikan region, the invertebrate filter-feeder Bugula neritina, and documented the continuing spread of three other non-native species.
