Published Compounds released by bleaching reefs promote bacteria, potentially stressing coral further
(via sciencedaily.com) Original source New research revealed that when coral bleaching occurs, corals release unique organic compounds into the surrounding water that not only promote bacterial growth overall, but select for opportunistic bacteria that may further stress reefs.
Published Researchers uncover a key link in legume plant-bacteria symbiosis
(via sciencedaily.com) Original source Researchers have unveiled a groundbreaking discovery shedding light on the intricate play between legume plants and nitrogen-fixing bacteria. Their study details the crucial role played by phosphorylation in driving the formation of symbiotic organs, known as nodules, on plant roots. The long-term goal is to enable symbiosis in root nodules in important crops such as barley, maize and rice to avoid the use of chemical fertilizers.
Published 3D ice printing can create artificial blood vessels in engineered tissue
(via sciencedaily.com) Original source A new 3D printing method uses ice to build a template for artificial blood vessels in engineered tissue. Researchers hope the vessels could eventually be used in artificial organ transplants or drug testing.
Published How ancient sea creatures can inform soft robotics
(via sciencedaily.com) Original source Fossils of a marine animal that lived 500 million years ago, combined with computer simulations, informed the design of a new soft robot.
Published Five dazzling new species of eyelash vipers discovered in Colombia and Ecuador
(via sciencedaily.com) Original source Scientists have discovered five dazzling new species of eyelash vipers in the jungles and cloud forests of Colombia and Ecuador.
Published Understanding chronic wasting disease in deer
(via sciencedaily.com) Original source A new collaborative study analyzed fecal samples to shed light on how the fatal disease impacts the gut microbiome in deer, providing a promising tool for disease surveillance.
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 Scientists develop artificial 'worm gut' to break down plastics
(via sciencedaily.com) Original source A team of scientists has developed an artificial 'worm gut' to break down plastics, offering hope for a nature-inspired method to tackle the global plastic pollution problem.
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 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 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 Dinosaurs' success helped by specialized stance and gait, study finds
(via sciencedaily.com) Original source Dinosaurs' range of locomotion made them incredibly adaptable, researchers have found.
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 Gut microbiome changes during pregnancy may influence immune system response
(via sciencedaily.com) Original source A new study identifies numerous pathways by which the gut microbiome may change the immune system.
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 Microfluidic environments alter microbe behaviors, opening potential for engineering social evolution
(via sciencedaily.com) Original source A research group explored how the social evolution of microbes can be manipulated by tuning the physical parameters of the environment in which they live.
Published Scientists develop new biocontainment method for industrial organisms
(via sciencedaily.com) Original source Researchers have developed a new biocontainment method for limiting the escape of genetically engineered organisms used in industrial processes.
