Published Phage structure captured, to benefit biotech applications
(via sciencedaily.com) Original source Researchers have mapped out what a commonly-used form of phage looks like, which will help design better uses in future.
Published Heat-loving marine bacteria can help detoxify asbestos
(via sciencedaily.com) Original source Researchers have shown that extremophilic bacteria from high temperature marine environments can be used to reduce asbestos' toxicity.
Published Researcher uses mammal DNA to zoom into the human genome with unprecedented resolution
(via sciencedaily.com) Original source Scientists have precisely identified base pairs of the human genome that remained consistent over millions of years of mammalian evolution, and which play a crucial role in human disease. The team analyzed the genomes of 240 mammals, including humans and identified base pairs that were 'constrained' -- meaning they remained generally consistent -- across mammal species over the course of evolution. The most constrained base pairs in mammals were over seven times more likely to be causal for human disease and complex trait, and over 11 times more likely when researchers looked at the most constrained base pairs in primates alone.
Published A look inside stem cells helps create personalized regenerative medicine
(via sciencedaily.com) Original source Researchers have examined a specific type of stem cell with an intracellular toolkit to determine which cells are most likely to create effective cell therapies.
Published Ancestral mitoviruses discovered in mycorrhizal fungi
(via sciencedaily.com) Original source A new group of mitochondrial viruses confined to the arbuscular mycorrhizal fungi Glomeromycotina may represent an ancestral lineage of mitoviruses.
Published Scientists discover fire records embedded within sand dunes
(via sciencedaily.com) Original source A new study shows that sand dunes can serve as repositories of fire history and aid in expanding scientific understanding of fire regimes around the world.
Published A journey to the origins of multicellular life: Long-term experimental evolution in the lab
(via sciencedaily.com) Original source Over 3,000 generations of laboratory evolution, researchers watched as their model organism, 'snowflake yeast,' began to adapt as multicellular individuals. In new research, the team shows how snowflake yeast evolved to be physically stronger and more than 20,000 times larger than their ancestor. Their study is the first major report on the ongoing Multicellularity Long-Term Evolution Experiment (MuLTEE), which the team hopes to run for decades.
Published Crops evolved by swapping genetic modules between cells
(via sciencedaily.com) Original source Comparing individual cells across corn, sorghum, and millet reveals evolutionary differences among these important cereal crops, according to a new study. The findings bring researchers closer to pinpointing which genes control important agricultural traits such as drought tolerance, which will help scientists faced with a changing climate adapt crops to drier environments.
Published African rhinos share retroviruses not found in Asian rhinos or other related species
(via sciencedaily.com) Original source Rhinoceros belong to a mammalian order called odd-toed ungulates that also include horses and tapirs. They are found in Africa and Asia. Until recently, evidence suggested that throughout their evolutionary history, gamma-retroviruses such as Murine leukemia virus had not colonized their genomes, unlike most other mammalian orders. The colonization process is called retroviral endogenization and has resulted in most mammalian genomes being comprised of up to ten percent retroviral like sequences.
Published Basic 'toolkit' for organ development is illuminated by sea star
(via sciencedaily.com) Original source One of the basic and crucial embryonic processes to unfold in virtually every living organism is the formation of hollow, tubular structures that go on to form blood vessels or a digestive tract, and through branching and differentiation, complex organs including the heart and kidneys. This study illuminates fundamental design principles of tubulogenesis for all chordates, including mammals.
Published The bat's ability to convert energy into muscle power is affected by flight speed
(via sciencedaily.com) Original source Small bats are bad at converting energy into muscle power. Surprisingly, a new study led by Lund University in Sweden reveals that this ability increases the faster they fly.
Published Scientists create CRISPR-based drug candidate targeting the microbiome
(via sciencedaily.com) Original source A new drug candidate targeting E. coli in the gut is in phase 1 clinical trials. According to a new paper it may improve the well-being of blood cancer patients and reduce their mortality rate from E. coli infections.
Published 'Super-resolution' imaging technology
(via sciencedaily.com) Original source Researchers describe developing a super-resolution imaging platform technology to improve understanding of how nanoparticles interact within cells.
Published Scientists develop gene silencing DNA enzyme that can target a single molecule
(via sciencedaily.com) Original source Researchers have developed a DNA enzyme -- or DNAzyme -- that can distinguish between two RNA strands inside a cell and cut the disease-associated strand while leaving the healthy strand intact. This breakthrough 'gene silencing' technology could revolutionize the development of DNAzymes for treating cancer, infectious diseases and neurological disorders.
Published T cells can activate themselves to fight tumors
(via sciencedaily.com) Original source Scientists find an auto-signaling mechanism driving the T cell anti-tumor response; findings may inspire new cancer therapeutics and biomarkers.
Published New probe aids novel findings on cell functions
(via sciencedaily.com) Original source New research shows the use of a new cellular probe helped discover new findings about certain cellular processes.
Published An unprecedented view of gene regulation
(via sciencedaily.com) Original source Using a new technique, researchers have shown that they can map interactions between gene promoters and enhancers with 100 times higher resolution than has previously been possible.
Published Tiny microbes could brew big benefits for green biomanufacturing
(via sciencedaily.com) Original source Scientists find new route in bacteria to decarbonize industry. The discovery could reduce greenhouse gas emissions from the manufacturing of fuels, drugs, and chemicals. A research team has engineered bacteria to produce new-to-nature carbon products that could provide a powerful route to sustainable biochemicals.
Published Elucidating the mysteries of enzyme evolution at the macromolecular level
(via sciencedaily.com) Original source Researchers have made a major breakthrough earlier this year in the field of evolutionary conservation of molecular dynamics in enzymes. Their work points to potential applications in health, including the development of new drugs to treat serious diseases such as cancer or to counter antibiotic resistance.
Published Researchers close to unleashing rapeseed's protein power for human consumption
(via sciencedaily.com) Original source Half of plant proteins in the EU come from rapeseed plants. Until now, the plant has only been used for oil and animal feed, as it is both bitter and unsafe for human consumption. In a new study, researchers have gotten closer to removing the plant's bitter substances, and in doing so, are paving the way for a new protein source to support the green transition.
