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 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 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 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.
Published Remarkable cellular architecture and phylogenetic position of the mysterious arm-swinging protist meteora sporadica
(via sciencedaily.com) Original source Researchers studied in detail the strange protist Meteora sporadica, which swings its two lateral arms back and forth. The results of the study indicated that M. sporadica has a complex cytoskeleton that is closely related to Hemimastigophora, a group of organisms considered to be one of the deepest branches of eukaryotes.
Published How plants obtain nitrogen by supplying iron to symbiotic bacteria
(via sciencedaily.com) Original source Researchers have discovered peptide factors that function in the shoot and root systems to transport iron into the root nodules colonized by nitrogen-fixing bacteria. Moreover, these peptide factors regulate nitrogen homeostasis by maintaining a balance between nitrogen and iron concentrations in plants without rhizobial symbiosis.
Published Two new freshwater fungi species in China enhance biodiversity knowledge
(via sciencedaily.com) Original source Researchers have discovered two new freshwater hyphomycete (mould) species, Acrogenospora alangii and Conioscypha yunnanensis, in southwestern China. The discovery marks the addition of these species to the Acrogenospora and Conioscypha genera, further enriching the diversity of freshwater fungi known in the region.
Published Flu virus variants resistant to new antiviral drug candidate lose pathogenicity
(via sciencedaily.com) Original source Influenza A viruses with induced resistance to a new candidate antiviral drug were found to be impaired in cell culture and weakened in animals, according to a new study.
Published How T cells combat tuberculosis
(via sciencedaily.com) Original source Scientists have uncovered important clues to how human T cells combat Mycobacterium tuberculosis, the bacterium that causes TB.
Published A rare recent case of retrovirus integration: An infectious gibbon ape leukaemia virus is colonizing a rodent's genome in New Guinea
(via sciencedaily.com) Original source Retroviruses are viruses that multiply by incorporating their genes into the genome of a host cell. If the infected cell is a germ cell, the retrovirus can then be passed on to the next generation as an 'endogenous' retrovirus (ERV) and spread as part of the host genome in that host species. In vertebrates, ERVs are ubiquitous and sometimes make up 10 per cent of the host genome. However, most retrovirus integrations are very old, already degraded and therefore inactive -- their initial impact on host health has been minimized by millions of years of evolution. A research team has now discovered a recent case of retrovirus colonization in a rodent from New Guinea, the white-bellied mosaic-tailed rat.
