University of Massachusetts Amherst food scientists have mapped and characterized microbial populations in a vegetable fermentation facility and report that its microbiome was distinct between production and fermentation areas and that the raw vegetables themselves -- cabbages destined for sauerkraut -- were the main source of fermentation-related microbes in production areas rather than handling or other environmental sources.
Indiana University researchers have identified cellular processes that appear to supercharge both the growth and shrinkage of the chemical 'caps' on chromosomes associated with aging, called telomeres.
New research for the first time reveals the three-dimensional structure of a membrane channel that's critical in controlling blood pressure. The findings, published today in the open-access journal eLife, represent the first time the human epithelial sodium channel has been shown so precisely since it was first isolated and described through expression cloning more than two decades ago.
A new study uses modern genetic sequencing tools to describe several distinct molecular signals produced by the optic gland after a female octopus reproduces. The research also details four separate phases of maternal behavior and links them to these signals, suggesting how the optic gland controls a mother octopus' demise.
A new technique to increase the efficiency of carbon dioxide (CO2) electrolysis that may lead to the production of new chemicals and fuels.
A joint effort between the University of Georgia and the University of Texas at Austin has discovered how ETEC works to cause disease. They are using this information in an effort to develop a preventive vaccine for travelers.
New research finds that 500 years of over-exploitation has halved mammal populations in South America's once majestic Atlantic Forest. A new analysis of mammal populations reveals the devastating effects of human disturbance since the area was first colonised in the 1500s. They found that apex predators and large carnivores, such as jaguars and pumas, as well as large-bodied herbivores, such as tapirs, were among the groups whose numbers had suffered the most.
More than 26,000 years ago, sea level was much lower than it is today partly because the ice sheets that jut out from the continent of Antarctica were enormous and covered by grounded ice -- ice that was fully attached to the seafloor. As the planet warmed, the ice sheets melted and contracted, and sea level began to rise. LSU Department of Geology & Geophysics Associate Professor Phil Bart and his students have discovered new information that illuminates how and when this global phenomenon occurred.
Massachusetts General Hospital researchers have found that extracellular RNA in urine may be a source of biomarkers for the two most common forms of muscular dystrophy, noninvasively providing information about whether therapeutic drugs are having the desired effects on a molecular level.
Princeton University researchers have proposed a US pipeline network that would capture, transport and store underground up to 30 million metric tons of carbon dioxide emissions each year -- an amount equal to removing 6.5 million cars from the road. The authors found that the network infrastructure would only be possible if tax credits passed by Congress in 2018 to encourage investment in carbon capture-and-storage technology are coupled with low-interest government financing.
