Published Researchers uncover genetic factors for severe Lassa fever
(via sciencedaily.com) Original source Researchers report the results of the first ever genome-wide association study (GWAS) of a biosafety level 4 (BSL-4) virus. The team found two key human genetic factors that could help explain why some people develop severe Lassa fever, and a set of LARGE1 variants linked to a reduced chance of getting Lassa fever. The work could lay the foundation for better treatments for Lassa fever and other similar diseases. The scientists are already working on a similar genetics study of Ebola susceptibility.
Published Surprise discovery of tiny insect-killing worm
(via sciencedaily.com) Original source Scientists have discovered a tiny worm species that infects and kills insects. These worms, called nematodes, could control crop pests in warm, humid places where other beneficial nematodes are currently unable to thrive.
Published How fruit flies control the brain's 'steering wheel'
(via sciencedaily.com) Original source A newly discovered neural circuit mediates between navigational brain cells, acting as a sort of mental steering wheel.
Published 'Legacy' phosphorus delays water quality improvements in Gulf of Mexico
(via sciencedaily.com) Original source The same phosphorus that fertilizes the thriving agriculture of the Midwest is also responsible for a vast 'dead zone' in the Gulf of Mexico near the Mississippi Delta. Efforts to reduce the amount of phosphorus that enters the Mississippi River system are underway, but research suggests that remnants of the contaminant are left behind in riverbeds for years after introduction and pose an overlooked -- and lingering -- problem.
Published Ancient rocks improve understanding of tectonic activity between earthquakes
(via sciencedaily.com) Original source Rocks once buried deep in ancient subduction zones -- where tectonic plates collide -- could help scientists make better predictions of how these zones behave during the years between major earthquakes, according to a research team.
Published Friend or foe? Ancient partnership between moss and fungi
(via sciencedaily.com) Original source Researchers have shed new light on the ancient relationship between moss and fungi. They discovered that intricate moss-fungi interactions often depended on a third variable -- the presence of endobacteria within the fungi themselves.
Published Researchers discover new cell that remembers allergies
(via sciencedaily.com) Original source Researchers have made a groundbreaking discovery: a new cell that remembers allergies.
Published Replacing animal-based foods with alternative proteins would unlock land for carbon removal
(via sciencedaily.com) Original source Researchers report that replacing 50% of animal products with alternative proteins by 2050 could free up enough agricultural land to generate renewable energy equivalent in volume to today's coal-generated power while simultaneously removing substantial CO2 from the atmosphere.
Published New research uncovers biological drivers of heart disease risk
(via sciencedaily.com) Original source Over the past 15 years, researchers have identified hundreds of regions in the human genome associated with heart attack risk. However, researchers lack efficient ways to explore how these genetic variants are molecularly connected to cardiovascular disease, limiting efforts to develop therapeutics. To streamline analysis of hundreds of genetic variants associated with coronary artery disease (CAD), a team of researchers combined multiple sequencing and experimental techniques to map the relationship between known CAD variants and the biological pathways they impact.
Published Organic compound found in trees could prevent contact lens eye infections
(via sciencedaily.com) Original source Researchers say hydroquinine could be an effective naturally occurring disinfecting solution for contact lenses and help combat keratitis infections.
Published Clarity needed for businesses to achieve greenhouse gas mitigation
(via sciencedaily.com) Original source Despite efforts to mitigate the effects of climate change, companies are not set up for success, due to conflicting national and sectorial targets and differing availability of abatement options, a new study reveals.
Published New study sheds new light on forests' role in climate and water cycle
(via sciencedaily.com) Original source Forests, which cover a third of Earth's land surface, are pivotal in carbon storage and the water cycle, though the full scope of their impact remains to be fully understood. In a new study, researchers provide new insights into the complex role forests play in the climate system and water cycle.
Published Inexpensive, carbon-neutral biofuels are finally possible
(via sciencedaily.com) Original source When it comes to making fuel from plants, the first step has always been the hardest -- breaking down the plant matter. A new study finds that introducing a simple, renewable chemical to the pretreatment step can finally make next-generation biofuel production both cost-effective and carbon neutral.
Published New approach for fast and cost-effective pathogen detection
(via sciencedaily.com) Original source The ability to detect diseases at an early stage or even predict their onset would be of tremendous benefit to doctors and patients alike. A research team now develops intelligent, miniaturized biosensor devices and systems using nanomaterials to determine biomolecules and cells as well as biochemical reactions or processes as disease markers. The team's current publication describes the development of a portable, palm-sized test system that can simultaneously carry out up to thirty-two analyses of one sample.
Published Warmer water may help rivers keep antimicrobial resistance at bay
(via sciencedaily.com) Original source New study suggests that temperature can influence the microbial competition in rivers.
Published Bacteria in the mouth linked to pulmonary fibrosis survival
(via sciencedaily.com) Original source Bacteria in the mouth may play a role in survival from idiopathic pulmonary fibrosis (IPF), finds a new study.
Published How kelp forests persisted through the large 2014-2016 Pacific marine heatwave
(via sciencedaily.com) Original source New research reveals that denser, and more sheltered, kelp forests can withstand serious stressors amid warming ocean temperatures.
Published New approach to tackling bacterial infections identified
(via sciencedaily.com) Original source Researchers have identified a new approach to controlling bacterial infections. The team found a way to turn on a vital bacterial defense mechanism to fight and manage bacterial infections. The defense system, called cyclic oligonucleotide-based antiphage signaling system (CBASS), is a natural mechanism used by certain bacteria to protect themselves from viral attacks. Bacteria self-destruct as a means to prevent the spread of virus to other bacterial cells in the population.
Published Researchers discover key to molecular mystery of how plants respond to changing conditions
(via sciencedaily.com) Original source A team of researchers recently published a pioneering study that answers a central question in biology: how do organisms rally a wide range of cellular processes when they encounter a change -- either internally or in the external environment -- to thrive in good times or survive the bad times? The research, focused on plants, identifies the interactions between four compounds: pectin, receptor proteins FERONIA and LLG1 and the signal RALF peptide.
Published Complex tree canopies help forests recover from moderate-severity disturbances
(via sciencedaily.com) Original source Extreme events wipe out entire forests, dramatically eliminating complex ecosystems as well as local communities. Researchers have become quite familiar with such attention-grabbing events over the years. They know less, however, about the more common moderate-severity disturbances, such as relatively small fires, ice storms, and outbreaks of pests or pathogens.
