Published Nitrogen interventions as a key to better health and robust ecosystems
(via sciencedaily.com) Original source An international research team combined multidisciplinary methods to evaluate how nitrogen interventions could improve air quality and reduce nitrogen deposition. Their study found that interventions, such as improving fuel combustion conditions, increasing agricultural nitrogen use efficiency, and reducing food loss and waste, could significantly lower premature deaths attributed to air pollution, crop losses, and ecosystems risks.
Published Scientists discover phenomenon impacting Earth's radiation belts
(via sciencedaily.com) Original source Two scientists discovered a new type of 'whistler,' an electromagnetic wave that carries a substantial amount of lightning energy to the Earth's magnetosphere.
Published Decoding mysterious seismic signals
(via sciencedaily.com) Original source Geophysicists find link between seismic waves called PKP precursors and anomalies in Earth's mantle that are associated with hotspots associated with volcanism on the surface.
Published Scottish and Irish rocks confirmed as rare record of 'snowball Earth'
(via sciencedaily.com) Original source The study found that the Port Askaig Formation, composed of layers of rock up to 1.1 km thick, was likely laid down between 662 to 720 million years ago during the Sturtian glaciation -- the first of two global freezes thought to have triggered the development of complex, multicellular life.
Published It's a rave: Underground acoustics amplify soil health
(via sciencedaily.com) Original source Barely audible to human ears, healthy soils produce a cacophony of sounds in many forms -- a bit like an underground rave concert of bubble pops and clicks. Special recordings made by ecologists show this chaotic mixture of soundscapes can be a measure of the diversity of tiny living animals in the soil, which create sounds as they move and interact with their environment.
Published New research shows unprecedented atmospheric changes during May's geomagnetic superstorm
(via sciencedaily.com) Original source On May 11, a gorgeous aurora surprised stargazers across the southern United States. That same weekend, a tractor guided by GPS missed its mark. What do the visibility of the northern lights have in common with compromised farming equipment in the Midwest? A uniquely powerful geomagnetic storm, according to new research.
Published The banana apocalypse is near, but biologists might have found a key to their survival
(via sciencedaily.com) Original source The bananas in your supermarket and that you eat for breakfast are facing functional extinction due to the disease Fusarium wilt of banana (FWB) caused by a fungal pathogen called Fusarium oxysporum f.sp. cubense (Foc) tropical race 4 (TR4). However, thanks to recent research from an international team of scientists we now know that Foc TR4 did not evolve from the strain that wiped out commercial banana crops in the 1950s and that the virulence of this new strain seems to be caused by some accessory genes that are associated the production of nitric oxide. The research opens the door to treatments and strategies that can slow, if not control, the as-of-yet unchecked spread of Foc TR4.
Published Probiotics during pregnancy shown to help moms and babies
(via sciencedaily.com) Original source Giving probiotics to pregnant mice can enhance both the immune system and behavior of the mothers and their offspring.
Published Scientists discover superbug's rapid path to antibiotic resistance
(via sciencedaily.com) Original source Scientists have discovered how the hospital superbug C.diff rapidly evolves resistance to the frontline drug used for treatment in the UK.
Published Researchers help to control cancer-causing poison in corn
(via sciencedaily.com) Original source Researchers have demonstrated a promising sterilization technique that uses X-ray irradiation to reduce Aspergillus flavus viability in contaminated corn. This method achieves sterilization without degrading the harmful aflatoxin B1 (AFB1) produced by the fungus.
Published As human activities expand in Antarctica, scientists identify crucial conservation sites
(via sciencedaily.com) Original source Establishing Key Biodiversity Areas in the Southern Ocean will be vital for safeguarding the ecosystem from the impact of human activities, researchers say.
Published Surprise finding in study of environmental bacteria could advance search for better antibiotics
(via sciencedaily.com) Original source Researchers studying bacteria from freshwater lakes and soil say they have determined a protein's essential role in maintaining the germ's shape. Because the integrity of a bacterial cell's 'envelope' or enclosure is key to its survival, the finding could advance the search for new and better antibiotics.
Published Scientists map DNA of Lyme disease bacteria
(via sciencedaily.com) Original source Researchers have produced a genetic analysis of Lyme disease bacteria that may pave the way for improved diagnosis, treatment, and prevention of the tick-borne ailment.
Published Warming waters and nutrient overload: A dangerous combination threatening our rivers and lakes
(via sciencedaily.com) Original source New international research found that food webs are becoming less complex in warmer, nutrient-rich waters.
Published Candidate malaria vaccine provides lasting protection in NIH-sponsored trials
(via sciencedaily.com) Original source Recent trials of an experimental malaria vaccine in healthy Malian adults found that all three tested regimens were safe. One of the trials enrolled 300 healthy women ages 18 to 38 years who anticipated becoming pregnant soon after immunization. That trial began with drug treatment to remove malaria parasites, followed by three injections spaced over a month of either saline placebo or the investigational vaccine at one of two dosages.
Published Researchers unveil mysteries of ancient Earth
(via sciencedaily.com) Original source A team of researchers has made strides in understanding the formation of massif-type anorthosites, enigmatic rocks that only formed during the middle part of Earth's history. These plagioclase-rich igneous rock formations, which can cover areas as large as 42,000 square kilometers and host titanium ore deposits, have puzzled scientists for decades due to conflicting theories about their origins.
Published Diet is main risk factor for colon cancer in younger adults, new study suggests
(via sciencedaily.com) Original source A new study has identified diet-derived molecules called metabolites as main drivers of young-onset colorectal cancer risk, especially those associated with red and processed meat. The report, which analyzed metabolite and microbiome datasets, highlighted that one of the best ways a younger (less than 60 years) adult can prevent colorectal cancer is to discuss their diet with their doctor.
Published A taste for carbon dioxide
(via sciencedaily.com) Original source The remarkable affinity of the microbial enzyme iron nitrogenase for the greenhouse gas CO2 makes it promising for future biotechnologies.
Published Hydrometeorology and location affect hospitalizations for waterborne infectious diseases in the US
(via sciencedaily.com) Original source An analysis of 12 years of data collected from over 500 hospitals in 25 different states shows that weather, geographic location, and urban or rural location all appear to influence hospitalizations for waterborne infectious diseases.
Published Revealing the mysteries within microbial genomes
(via sciencedaily.com) Original source A new technique will make it much easier for researchers to discover the traits or activities encoded by genes of unknown function in microbes, a key step toward understanding the roles and impact of individual species within the planet's diverse microbiomes.
